The patient-specific functional scale: validation of its use in persons with neck dysfunction

Process of change for people with knee osteoarthritis undergoing cognitive functional therapy: a replicated single-case experimental design study

PURPOSE

To examine the applicability and process of change of Cognitive Functional Therapy (CFT) in the management of pain and disability in people with knee osteoarthritis who were offered knee replacement surgery and had risk factors for poor response to surgery.

METHODS

Single-case experimental design with a mixed-methods, repeated measures approach was used to investigate the process of change through CFT in four participants. Qualitative interviews investigated beliefs, behaviours and coping responses, and self-reported measures assessed pain, disability, psychological factors, and function at 25 timepoints. Study registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12619001491156).

RESULTS

Qualitative data indicate that CFT promoted helpful changes in all participants, with two responses observed. One reflected a clear shift to a biopsychosocial conceptualisation of osteoarthritis, behavioural re-engagement and the view that a knee replacement was no longer necessary. The other response reflected a mixed conceptualisation with dissonant beliefs about osteoarthritis and its management. Psychological and social factors were identified as potential treatment barriers. Overall, quantitative measures supported the qualitative findings.

CONCLUSION

The process of change varies between and within individuals over time. Psychological and social barriers to treatment have implications for future intervention studies for the management of knee osteoarthritis.IMPLICATIONS FOR REHABILITATIONCognitive Functional Therapy is applicable in the management of knee osteoarthritis.Reconceptualisation of osteoarthritis reflected a helpful change.Psychological and social factors emerged as barriers to recovery.

Cross-cultural adaptation and psychometric properties of the Italian version of the Patient-Specific Functional Scale (PSFS) in subjects with shoulder pain

PURPOSE

To cross-culturally adapt the Patient-Specific Functional Scale (PSFS) into Italian and study its classic psychometric properties in subjects with shoulder pain (SP).

MATERIALS AND METHODS

The PSFS was translated into Italian and administered to 109 SP subjects. Acceptability (time to administer, floor and ceiling effects), reliability (internal consistency [Cronbach's alpha], test-retest reliability [Intraclass Correlation Coefficient (ICC)], and measurement error [Standard Error of Measurement (SEM), Minimal Detectable Change, (MDC)]), were assessed. Moreover, construct validity was investigated through a-priori hypothesis testing, comparing the PSFS with the Disability of the Shoulder, Arm and Hand (DASH) scale, 36-item Short Form Health Survey (SF-36) and Numeric Pain Rating scale (NPRS).

RESULTS

The PSFS was successfully adapted into Italian, and its acceptability was satisfied. Internal consistency was high (Cronbach's alpha = 0.925), and test-retest reliability was good (ICC = 0.866, 95% CI = 0.749-0.931). A SEM of 0.7 points and an MDC of 1.9 points were obtained. We observed moderate evidence for construct validity, with 4/6 correlations between other measures being respected.

CONCLUSION

This study provided reliability and validity of the PSFS in a sample of Italian SP subjects. Future studies should assess the responsiveness of using the PSFS as an outcome measure to capture clinical changes after treatment.

Changes in Multiple Aspects of Pain Outcomes After Rehabilitation: Analysis of Pain Data in a Randomized Controlled Trial Evaluating the Effects of Adding Sensorimotor Training to Manual Therapy and Exercise for Chronic Neck Pain

OBJECTIVES

To examine changes in pain outcomes to fully evaluate the effect of adding sensorimotor training to manual therapy and exercise in patients with chronic neck pain and sensorimotor deficits. Concordance was examined between pain distribution and pain intensity and patient-reported outcomes.

METHODS

Participants (n=152) were randomly allocated into 4 intervention groups: One group received local neck treatment (NT) comprising manual therapy and exercise and the other 3 groups received additional sensorimotor training (either joint position sense/oculomotor exercises, balance exercises or both). Treatment was delivered twice a week for 6 weeks. Pain and patient-reported outcomes were measured at baseline, posttreatment, and 3-, 6- and 12-month follow-ups.

RESULTS

There were greater changes in pain location, extent, and intensity at 6- and 12-month follow-ups in the sensorimotor training groups compared with the NT group ( P <0.05). A greater number of patients in the sensorimotor training groups gained ≥50% reduction in pain extent and intensity relative to the NT group at 6 and 12 months ( P <0.05). Clinical improvement in pain extent was concordant with pain intensity (adjusted kappa=056 to 0.66, %agreement=78.3 to 82.9, P <0.001) and disability (adjusted kappa=0.47 to 0.58, % agreement=73.7 to 79.0, P <0.01) at 3-, 6- and 12-month follow-ups, but not with function and well-being. The concordance tended to decline with time.

DISCUSSION

Multiple aspects of the pain experience improved in the longer term by adding sensorimotor training to NT for patients with neck pain and sensorimotor deficits. The concordance between pain and patient-reported outcomes was not always evident and varied over time, suggesting the need for multidimensional assessments of pain.

Reliability, Measurement Error, Responsiveness, and Minimal Important Change of the Patient-Specific Functional Scale 2.0 for Patients With Nonspecific Neck Pain

OBJECTIVE

The Patient-Specific Functional Scale (PSFS) is a patient-reported outcome measure used to assess functional limitations. Recently, the PSFS 2.0 was proposed; this instrument includes an inverse numeric rating scale and an additional list of activities that patients can choose. The aim of this study was to assess the test-retest reliability, measurement error, responsiveness, and minimal important change of the PSFS 2.0 when used by patients with nonspecific neck pain.

METHODS

Patients with nonspecific neck pain completed a numeric rating scale, the PSFS 2.0, and the Neck Disability Index at baseline and again after 12 weeks. The Global Perceived Effect (GPE) was also collected at 12 weeks and used as an anchor. Test-retest measurement was assessed by completion of a second PSFS 2.0 after 1 week. Measurement error was calculated using a Bland-Altman plot. The receiver operating characteristic method with the anchor (GPE) functions as the reference standard was used for calculating the minimal important change.

RESULTS

One hundred patients were included, with 5 lost at follow-up. No floor and ceiling effects were reported. In the test-retest analysis, the mean difference was 0.15 (4.70 at first test and 4.50 at second test). The ICC (mixed models) was 0.95, indicating high agreement (95% CI = 0.92-0.97). For measurement error, the upper and lower limits of agreement were 0.95 and -1.25 points, respectively, with a smallest detectable change of 1.10. The minimal important change was determined to be 2.67 points. The PSFS 2.0 showed satisfactory responsiveness, with an area under the curve of 0.82 (95% CI = 0.70-0.93). There were substantial to high correlations between the change scores of the PSFS 2.0 and the Neck Disability Index and GPE (0.60 and 0.52, respectively; P < .001).

CONCLUSION

The PSFS 2.0 is a reliable and responsive patient-reported outcome measure for use by patients with neck pain.

Improvements after dry needling for craniofacial pain in a patient with chronic rhinosinusitis: a case report

BACKGROUND

Typically treated medically, chronic rhinosinusitis (CRS) is a prevalent condition characterized by multiple craniofacial symptoms, some of which may respond favorably to dry needling intervention.

OBJECTIVE

To describe the outcomes of a patient presenting with craniofacial pain and symptoms consistent with a diagnosis of CRS who was treated with dry needling. Case Description: A 41-year-old male, self-referred to physical therapy with a diagnosis of CRS, with a 20-year history of signs and symptoms associated with CRS, including craniofacial pain and headaches. The patient had been treated with multiple medication regimens over this time, including antihistamines, anti-inflammatories, decongestants, leukotriene inhibitors, and antibiotics; all of which provided only short-term relief. On initial examination, the patient was tender to palpation in multiple muscles of the head, neck, and face. Intervention consisted of dry needling to these muscular tender points once or twice weekly over 2 months.

OUTCOMES

After 2 months of dry needling, the patient demonstrated clinically meaningful improvements in pain and quality of life, which included a decrease in both medication usage and the frequency of sinus infections.

CONCLUSION

Although CRS is generally managed medically, we observed areas of muscular tenderness in this case, which were effectively managed with dry needling. Rehabilitative providers may consider screening CRS patients for muscular impairments that may be modifiable with dry needling. Further research should be performed to determine whether dry needling has a role in the management of CRS.

Cross-Cultural Adaptation and Psychometric Validation of the Hindi Version of the Neck Disability Index in Patients With Chronic Neck Pain

STUDY DESIGN

Translation and psychometric testing.

OBJECTIVES

To cross-culturally adapt the Neck Disability Index (NDI) into the Hindi language, the local language of India, and to investigate the psychometric properties of the Neck Disability Index-Hindi (NDI-H) version in patients with neck pain.

SUMMARY OF BACKGROUND DATA

The NDI is the most used self-reported outcome measure for neck pain. The previous NDI-H version did not obtain advance permission from Mapi trust to translate this scale. As a result, this scale's availability is limited.

MATERIALS AND METHODS

Following established guidelines, the NDI was translated and culturally adapted into Hindi. A total of 120 chronic neck pain patients (20 for cognitive interviews and 100 for psychometric testing) participated in this study. The content validity, construct validity, internal consistency, test-retest reliability, and responsiveness of the NDI-H were all evaluated. The intraclass correlation coefficient was computed to determine test-retest reliability. Internal consistency was assessed using Cronbach α. The NDI's factor structure was investigated using principal component factor analysis. The Neck Pain and Disability Scale, Numeric Pain Rating Scale, and Anxiety and Depression scales were used to test criterion validity. The receiver operating characteristic curve analysis was used to determine the cut-off point and the area under the curve.

RESULTS

The NDI-H demonstrated good test-retest reliability (intraclass correlation coefficient = 0.92) and excellent internal consistency (Cronbach α = 0.90). The one-factor structure was revealed by the factor analysis. The NDI has a strong relationship with the Neck Pain and Disability Scale and Numeric Pain Rating Scale, as well as the Anxiety and Depression scales. The cut-point for detecting a change was 9.3.

CONCLUSIONS

The NDI was successfully translated into Hindi in this study. The NDI-H is a reliable and valid and responsive instrument that can be used to treat patients with chronic neck pain in clinical and research settings.

The effectiveness of cognitive behavioural therapy in chronic neck pain: A systematic review with meta-analysis

We evaluated the effects of Cognitive Behavioural Therapy (CBT) alone or with additional interventions on pain, disability, kinesiophobia, anxiety, stress, depression, quality of life, and catastrophizing of patients with chronic neck pain (CNP). Nineteen studies met the inclusion criteria, and fourteen studies were quantitatively analysed. Risk of bias was assessed using the PEDro scale and the certainty of evidence using the GRADE approach. Studies were pooled (where applicable) and subgroup analyses were performed for CNP, or whiplash associated disorders. Studies compared-directly or indirectly-CBT interventions to no treatment, conservative interventions such as exercise and/or physiotherapy, or multimodal interventions. We present effect estimates at 8-week, 12-week, 6-month, and 1-year follow-up. Low certainty evidence suggests a clinically significant pain reduction (short-term) favouring CBT with or without additional intervention compared to no intervention SMD = -0.73; 95%CI: -1.23 to -0.23). Very low and low certainty evidence suggest clinically significant improvements in kinesiophobia (very short-term SMD = -0.83; 95%CI: -1.28 to -0.39 and short-term SMD = -1.30, 95%CI: -1.60 to -0.99), depression SMD = -0.74, 95%CI: -1.35 to -0.14) and anxiety SMD = -0.76, 95%CI: -1.34 to -0.18) favouring a multimodal intervention with CBT (short-term) compared to other conservative interventions. Combining different types of CBT interventions resulted in potentially heterogeneous comparisons.

Protocol for a Parallel Group Randomized Clinical Trial Comparing a Culturally Adapted Cognitive Behavioral Telerehabilitation Intervention to Usual Physical Therapy for Latino Patients With Chronic Spine Pain

OBJECTIVE

Disparities exist in health care access, diagnosis, and treatment of chronic pain in Latino populations and other minority populations. Cognitive behavioral-based physical therapy (CBPT) interventions have been shown to be effective in predominantly non-Hispanic white populations with chronic spine pain. However, there is a need for culturally adapted CBPT interventions that focus on the conservative management of chronic spine pain. The primary purpose of the study described in this protocol is to test the efficacy of an adapted cognitive behavioral-based hybrid telerehabilitation intervention for Latino patients with chronic spine pain.

METHODS

A single-blind, 2-arm parallel group, superiority randomized clinical trial is planned to compare an adapted CBPT intervention to Usual Care physical therapy. Goal Oriented Activity for Latinos with chronic Spine pain (GOALS/Metas) is an 8-week hybrid telerehabilitation intervention that integrates guideline-based physical therapy and pain management interventions using cognitive behavioral approaches and has been adapted for Latino patients with chronic spine pain. Usual Care physical therapy will be administered based on institutional standards at the referring health center. Outcome measures will be evaluated preintervention and at 1-week, 3-months, and 6-months postintervention. The primary outcome is pain-related disability 1-week postintervention using the Brief Pain Inventory Pain Interference subscale. Secondary outcome measures include behavioral measures of functional activity, social participation, physical activity, and sleep. Determinants of treatment effect, including pain-related psychological measures, posture and movement, self-efficacy, treatment expectancy, and therapeutic alliance, will be included in the secondary moderation and mediation analyses.

IMPACT

This clinical trial will provide information on the extent to which an adapted CBPT hybrid telerehabilitation intervention is effective in reducing pain-related disability for Latino patients with chronic spine pain. This information will be useful for clinicians to integrate in their practice, given the growing population of Latino patients who experience disparities in health care management of chronic pain.

Feasibility of using remotely delivered Spring Forest Qigong to reduce neuropathic pain in adults with spinal cord injury: a pilot study

Introduction: Approximately 69% of 299,000 Americans with spinal cord injury (SCI) suffer debilitating chronic neuropathic pain, which is intractable to treatment. The aim of this study is to determine feasibility, as the primary objective, and estimates of efficacy of a remotely delivered Qigong intervention in adults with SCI-related neuropathic pain, as the secondary objective. Methods: We recruited adults with SCI-related neuropathic pain, with SCI ≥3 months, with complete or incomplete SCI, and highest neuropathic pain level of >3 on the Numeric Pain Rating Scale (NPRS), using nationwide volunteer sampling. Using a non-randomized controlled trial design, participants practiced Spring Forest Qigong's "Five Element Qigong Healing Movements" (online video) by combining movement to the best of their ability with kinesthetic imagery, at least 3x/week for 12 weeks. Adherence was automatically tracked through the Spring Forest Qigong website. Outcomes of neuropathic pain intensity (NPRS) were assessed weekly, and SCI-related symptoms were assessed at baseline, 6, and 12 weeks of Qigong practice and at 6-week and 1-year follow-ups. Results: We recruited 23 adults with chronic SCI (7/2021-2/2023). In total, 18 participants started the study and completed all study components, including the 6-week follow-up. Twelve participants completed the 1-year follow-up assessment. Feasibility was demonstrated through participants' willingness to participate, adherence, and acceptability of the study. Mean age of the 18 participants was 60 ± 12 years, and they were 15 ± 11 years post-SCI with the highest baseline neuropathic pain of 7.94 ± 2.33, which was reduced to 4.17 ± 3.07 after 12 weeks of Qigong practice (Cohen's d = 1.75). This pain relief remained at 6-week and 1-year follow-ups. Participants reported reduced spasm frequency (change score 1.17 ± 1.20, d = 0.98) and severity (0.72 ± 1.02, d = 0.71), reduced interference of neuropathic pain on mood (3.44 ± 2.53, d = 1.36), sleep (3.39 ± 2.40, d = 1.41), daily activities (3.17 ± 2.77, d = 1.14), greater ability to perform functional activities (6.68 ± 3.07, d = 2.18), and improved mood (2.33 ± 3.31, d = 0.70) after Qigong. Discussion: Remote Spring Forest Qigong's "Five Element Qigong Healing Movements" practice is feasible in adults with SCI-related neuropathic pain, with promising prolonged results of neuropathic pain relief and improvement in SCI-related symptoms after Qigong practice.

Using remotely delivered Spring Forest Qigong™ to reduce neuropathic pain in adults with spinal cord injury: protocol of a quasi-experimental feasibility clinical trial

BACKGROUND

About 69% of Americans living with spinal cord injury (SCI) suffer from long-term debilitating neuropathic pain, interfering with the quality of daily life. Neuropathic pain is refractory to many available treatments-some carrying a risk for opioid addiction-highlighting an urgent need for new treatments. In this study, we will test our hypothesis that Spring Forest Qigong™ will reduce SCI-related neuropathic pain by improving body awareness. We will determine whether remotely delivered Qigong is feasible and we will collect data on neuropathic pain, and other reported associations with pain such as spasms frequency and/or severity, functional performance, mood, and body awareness.

METHODS

In this quasi-experimental pilot clinical trial study, adults with SCI will practice Qigong at home with a 45-min video, at least 3 × /week for 12 weeks. The Qigong practice includes movements with guided breathing and is individualized based on functional abilities, i.e., the participants follow along with the Qigong movements to the level of their ability, with guided breathing, and perform kinesthetic imagery by focusing on the feeling in the whole body as if doing the whole-body Qigong movement while standing. The highest, average, and lowest neuropathic pain ratings perceived in the prior week will be recorded weekly until the 6-week follow-up. The other outcomes will be collected at 5 time points: at baseline, midway during the Qigong intervention (6 weeks), after the Qigong intervention (12 weeks), after a 6-week and 1-year follow-up. Rate parameters for the feasibility markers will be estimated based on the participants who achieved each benchmark.

DISCUSSION

The University of Minnesota (UMN)'s Institutional Review Board (IRB) approved the study (IRB #STUDY00011997). All participants will sign electronic informed consent on the secure UMN REDCap platform. The results will be presented at academic conferences and published in peer-reviewed publications.

Development and measurement properties of the PEM/PESE activity questionnaire (PAQ)

BACKGROUND

Existing instruments often are inappropriate to measure the effects of post-exertional malaise (PEM) and post-exertional symptom exacerbation (PESE) on activities of daily living (ADLs). A validated questionnaire to measure self-reported ability with ADLs would advance research and clinical practice in conditions like myalgic encephalomyelitis and Long Covid.

OBJECTIVE

Determine the measurement properties of the PEM/PESE Activity Questionnaire (PAQ).

METHODS

The PAQ is adapted from the Patient Specific Functional Scale. Respondents rated three self-selected ADLs on two 0-100 scales, including current performance compared to (1) a 'good day' and (2) before illness. Respondents provided a Burden of Functioning rating on a 0-100 scale, anchored at 0 being the activity took "No time, effort, and resources at all" and 10 being "All of my time, effort, and resources." Respondents took the PAQ twice, completing a demographic questionnaire after the first PAQ and before the second PAQ. Descriptive statistics and intraclass correlation coefficients were calculated for each scale to assess test-retest reliability. Minimum detectable change outside the 95% confidence interval (MDC95) was calculated. Ceiling and floor effects were determined when the MDC95 for average and function scores crossed 0 and 100, respectively.

RESULTS

n = 981 responses were recorded, including n = 675 complete surveys. Test-retest reliability was generally fair to excellent, depending on function and scale. MDC95 values generally indicated scale responsiveness. Ceiling and floor effects were noted infrequently for specific functions.

CONCLUSION

The PAQ is valid, reliable, and sensitive. Additional research may explore measurement properties involving functions that were infrequently selected in this sample.

Pain management with epidural catheter and epidural analgesia after spinal dorsal instrumentation of lumbar spine

Spinal dorsal instrumentation (SDI) is an established treatment for degenerative spinal diseases. Adequate and immediate postoperative pain control is important for patient recovery and may be compromised by uncertainty about its efficacy and concern about early postoperative surgical complications or adverse events. The aim of the current study was to compare the use of epidural analgesia (EA) with systemic analgesia (SA) as regards pain reduction and early postoperative complications after SDI. Pain management with epidural or systemic analgesia in patients undergoing SDI by posterior approach between January 2019 and July 2020 was evaluated by clinical functional testing, measuring total opioid amounts used, and evaluating numerical rating scale values 24 and 96 hours postoperatively. The following were also monitored: demographic data, number of affected segments, length of hospital stay, inflammatory markers (leukocytes and serum C-reactive protein), early postoperative surgical complication rates, and adverse events. In total 79 patients were included (33 in the EA and 46 in the SA group). The SA group had significantly lower numerical rating scale values at days 1 to 4 after surgery (P ≤ .001) and lower cumulative opioid use than the EA group (P < .001). We found no difference in infection parameters, length of hospital stay or surgery-related complication rates. Our data demonstrate that epidural anesthesia was inferior to an opioid-based SA regime in reducing postoperative pain in patients undergoing spinal surgery. There is no benefit to the use of epidural catheters.

Effectiveness of adding rehabilitation of cervical related sensorimotor control to manual therapy and exercise for neck pain: A randomized controlled trial

BACKGROUND

Local neck treatments and sensorimotor training can improve cervical proprioception and balance, but it remains unclear what treatments and treatment combination achieve the best outcomes.

OBJECTIVES

To investigate the most effective interventions to improve disturbances in joint position sense (JPS) and balance and their effects on neck pain, dizziness and related features in the short- and long-terms.

DESIGN

2x2 factorial, randomized controlled trial.

METHODS

Participants with neck pain (n = 152) were randomly allocated to one of four intervention groups: i) local neck treatment (NT), ii) NT + JPS/oculomotor exercises (JPS/OC), iii) NT + balance exercises, and iv) all treatments. Participants received 12 treatments over 6 weeks. Primary outcomes were postural sway and joint position error. Secondary outcomes included gait speed, dizziness, pain intensity and disability, cervical range of motion, functional ability, and quality of life. Outcome measures were taken at baseline, posttreatment and 3-, 6- and 12-month follow-ups.

RESULTS

All four interventions resulted in short- and long-term improvements in primary and secondary outcomes with medium to large effect sizes, but JPS and balance in neck torsion improved most with the addition of a combined program of JPS/OC + balance exercises to NT while balance in neck neutral improved most with the addition of balance exercises. Adding sensorimotor training was also more effective in maintaining levels of improvement in neck pain and disability at 6- and 12-months. Effect sizes of additional treatment benefits were medium to large.

CONCLUSIONS

Adding specific training of JPS/OC and balance to NT best addresses deficits in cervical proprioception and balance.

Proof of concept and feasibility of a blended physiotherapy intervention for persons with haemophilic arthropathy

BACKGROUND

Regular physiotherapy with a physiotherapist experienced in the field is not feasible for many patients with haemophilia. We, therefore, developed a blended physiotherapy intervention for persons with haemophilic arthropathy (HA) (e-Exercise HA), integrating face-to-face physiotherapy with a smartphone application.

AIM

The aim of the study was to determine proof of concept of e- Exercise HA and to evaluate feasibility.

METHODS

Proof of concept was evaluated by a single-case multiple baseline design. Physical activity (PA) was measured with an accelerometer during a baseline, intervention and post-intervention phase and analysed using visual inspection and a single case randomisation test. Changes in limitations in activities (Haemophilia Activities List [HAL]) and a General Perceived Effect (GPE) were evaluated between baseline (T0), post-intervention (T1) and 3 months post-intervention (T2) using Wilcoxson signed rank test. Feasibility was evaluated by the number of adverse events, attended sessions and open-ended questions.

RESULTS

Nine patients with HA (90% severe, median age 57.5 (quartiles 50.5-63.3) and median HJHS 32 (quartiles 22-36)) were included. PA increased in two patients. HAL increased mean 15 (SD 9) points (p = .001) at T1, and decrease to mean +8 points (SD 7) (p = .012) at T2 compared to T0. At T1 and T2 8/9 participants scored a GPE > 3. Median 5 (range 4-7) face-to-face sessions were attended and a median 8 out of 12 information modules were viewed. No intervention-related bleeds were reported.

CONCLUSION

A blended physiotherapy intervention is feasible for persons with HA and the first indication of the effectiveness of the intervention in decreasing limitations in activities was observed.

Follow-up care and adherence to self-management activities in rehabilitation for patients with rheumatic and musculoskeletal diseases: results from a multicentre cohort study

PURPOSE

Follow-up care (FU-care) and self-management are recognized as important to ensure prolonged effects of rehabilitation. Objectives of this study were to explore current FU-care and self-management after specialized rehabilitation for patients with rheumatic and musculoskeletal diseases.

MATERIALS AND METHODS

This multicentre cohort study included 523 patients who self-reported need and plans for FU-care and plans for self-management activities (SMAs) at rehabilitation discharge. The FU-care received and adherence to SMA were self-reported after 4-, 8-, and 12-months. Predictors for received FU-care and adherence to SMA were explored in multiple logistic regression models.

RESULTS

Plans for FU-care were significantly associated with received FU-care. Younger age, better coping skills, and performing regular social activities and hobbies were significant predictors for received FU-care. Throughout the follow-up year, 221 (51%) participants had adherence to their SMA plans. Older age, regular physical activity, more severe pain, and performing regular social activities and hobbies were significant predictors for adherence to SMA. Participants with SMA adherence more often reported planned FU-care, and more frequently received the FU-care they needed.

CONCLUSIONS

Planning FU-care should be integrated in specialized rehabilitation. Patients with poor coping skills and sedentary lifestyle may need more support over longer time to implement behavioral changes for healthy self-management.Implications for rehabilitationPlanning follow-up should be integrated in specialized rehabilitation as it supports self-management and receiving follow-up at home.Patients with sedentary lifestyle, poor coping skills, and depression may need more support over longer time to implement healthy self-management.Structure and routines in daily life enhance self-management.

Predictors of pain reduction following a program of manual therapies for patients with temporomandibular disorders: A prospective observational study

BACKGROUND

Clinical guidelines recommend conservative treatment for the management of temporomandibular disorders (TMD), and manual therapy (MT) is commonly applied to reduce pain and improve function.

OBJECTIVES

To identify predictors of pain reduction and functional improvement following a program of manual therapies (MTP) in patients with TMD and develop a first screening tool that could be used in clinical practice to facilitate decision-making.

DESIGN

A cohort of 102 adults with a diagnosis of TMD were treated with four weekly sessions within a MTP applied to craniomandibular structures. Candidate predictors were demographic variables, general health variables, psychosocial features, TMD characteristics and related clinical tests. A reduction of pain intensity by at least 30% after the MTP was considered a good outcome. Logistic regression was adopted to develop the predictive model and its performance was assessed considering the explained variance, calibration, and discrimination. Internal validation of the prediction models was further evaluated in 500 bootstrapped samples.

RESULTS

Patients experiencing pain intensity greater than 2/10 during mouth opening, positive expectations of outcome following a MTP, pain localized in the craniocervical region, and a low Central Sensitization Inventory score obtained a good outcome following the MTP. Predictive performance of the identified physical and psychological variables was characterized by high explained variance (R2 = 58%) and discrimination (AUC = 89%) after internal validation. A preliminary screening clinical tool was developed and presented as a nomogram.

CONCLUSIONS

The high discrimination of the prediction model revealed promising findings, although these need to be externally validated in future research.

Rehabilitation goals described by patients with rheumatic and musculoskeletal diseases: content and attainment during the first year after rehabilitation

PURPOSE

We explored the content and attainment of rehabilitation goals the first year after rehabilitation among patients with rheumatic and musculoskeletal diseases.

METHODS

Participants (n = 523) recorded goals in the Patient Specific Functional Scale at admission and reported goal attainment at admission, discharge, and 12 months after rehabilitation on an 11-point numeric rating scale. Goal content was linked to the ICF coding system and summarized as high, maintained, or no attainment. Changes in absolute scores were investigated using paired samples t-tests.

RESULTS

Goals had high attainment with a significant positive change (-1.83 [95% CI -2.0, -1.65], p > 0.001) during rehabilitation, whereas goals had no attainment with a significant negative change (0.36 [0.14, 0.57], p > 0.001) between discharge and 12 months after rehabilitation. Goals focusing on everyday routines, physical health, pain management, and social or work participation were highly attained during rehabilitation. Goals that were difficult to enhance or maintain after rehabilitation addressed everyday routines, physical health, and work participation.

CONCLUSION

The positive changes in goal attainment largely occurred during rehabilitation, but they appeared more difficult to maintain at home. Therefore, rehabilitation goals should be reflected in the follow-up care planned at discharge.Implications for rehabilitationThe contents of rehabilitation goals reflect the complexity and wide range of challenges patients with rheumatic and musculoskeletal diseases experience.Positive changes in goal attainment largely occur during rehabilitation and appear to be more difficult to enhance or maintain at home.Rehabilitation interventions and follow-up care should be tailored to support patients in maintaining their attained goals for healthy self-management.Rehabilitation goals should be reflected in the follow-up care planned at discharge.

Identifying Body Awareness-Related Brain Network Changes After Cognitive Multisensory Rehabilitation for Neuropathic Pain Relief in Adults With Spinal Cord Injury: Protocol of a Phase I Randomized Controlled Trial

Background

About 69% of the 299,000 Americans living with spinal cord injury (SCI) experience long-term debilitating neuropathic pain. New treatments are needed because current treatments do not provide enough pain relief. We have found that insular-opercular brain network alterations may contribute to neuropathic pain and that restoring this network could reduce neuropathic pain. Here, we outline a study protocol using a physical therapy approach, cognitive multisensory rehabilitation (CMR), which has been shown to restore OP1/OP4 connections in adults post stroke, to test our hypothesis that CMR can normalize pain perception through restoring OP1/OP4 connectivity in adults with SCI and relieve neuropathic pain.

Objectives

To compare baseline brain function via resting-state and task-based functional magnetic resonance imaging in adults with SCI versus uninjured controls, and to identify changes in brain function and behavioral pain outcomes after CMR in adults with SCI.

Methods

In this phase I randomized controlled trial, adults with SCI will be randomized into two groups: Group A will receive 6 weeks of CMR followed by 6 weeks of standard of care (no therapy) at home. Group B will start with 6 weeks of standard of care (no therapy) at home and then receive 6 weeks of CMR. Neuroimaging and behavioral measures are collected at baseline, after the first 6 weeks (A: post therapy, B: post waitlist), and after the second 6 weeks (A: post-therapy follow-up, B: post therapy), with follow-up of both groups up to 12 months.

Conclusion

The successful outcome of our study will be a critical next step toward implementing CMR in clinical care to improve health in adults with SCI.

From protection to non-protection: A mixed methods study investigating movement, posture and recovery from disabling low back pain

BACKGROUND

Movement and posture are commonly believed to relate to low back pain (LBP). Yet, we know little about how people make sense of the relationship between their LBP, movement and posture, particularly after recovery. We aimed to qualitatively explore this understanding, how it changes and how it relates to quantitative changes.

METHODS

A mixed method study in the context of an existing single-case design involving 12 people with disabling non-specific LBP. Interviews were conducted before and after a 12-week physiotherapy-led Cognitive Functional Therapy intervention, and qualitative findings from these were integrated with individualized, quantitative measures of movement, posture, psychological factors, pain and activity limitation.

RESULTS

Strong beliefs about movement and posture were identified during the baseline interviews. Lived experiences of tension and stiffness characterized the embodiment of 'nonconscious protection', while healthcare and societal messages prompted pain-related fear and 'conscious protection'. Through varied journeys, most participants reported improvements over time with less protective movement and postural strategies. For some, being less protective required focused attention ('conscious non-protection'), but most returned to automatic, normal and fearless patterns ('nonconscious non-protection'), forgetting about their LBP. One participant reported no meaningful shift, remaining protective. Greater spinal range, faster movement, more relaxed postures and less back muscle EMG accompanied positive changes in self-report factors.

CONCLUSION

The findings offer a framework for understanding how people make sense of movement and posture during the process of recovery from persistent, disabling non-specific LBP. This involved a re-conceptualisation of movement and posture, from threatening, to therapeutic.

SIGNIFICANCE

Findings from qualitative interviews before and after a Cognitive Functional Therapy intervention in 12 people with disabling low back pain highlighted an individualized recovery journey from conscious and nonconscious protection to conscious non-protection for some, and nonconscious non-protection for many. Pre and post-quantitative measures of movement, posture, psychological factors, pain and activity limitation integrated well with the qualitative findings. The findings suggest movement and posture may form part of a multidimensional pain schema.

Validation of the patients-specific functional scale in patients with haemophilia

INTRODUCTION

A complete functional assessment is essential to measure health status and treatment effects in patients with haemophilia. The Patient-Specific Functional Scale (PSFS) is a reliable, valid, simple and quick scale that measures physical function in patients with musculoskeletal disorders. However, the reliability and validity of the PSFS have not been evaluated in patients with haemophilia.

AIM

The aim of this study was to validate the Patient-Specific Functional Scale in patients with haemophilia.

METHODS

Twenty-eight patients with haemophilia participated in the study. They completed the PSFS and the Haemophilia Activity List (HAL) scales by telephone during an initial session, and then repeated the assessment in a follow-up session 1 week apart. Reliability was analysed by the internal correlation coefficient (ICC), the standard error of measurement (SEM) and the smallest detectable change (SDC). The concurrent validity of the PSFS was determined by correlating the initial score of the PSFS scale to the initial score of the HAL scale. Correlations were calculated by means of scatter plots and Pearson product-moment r correlation coefficient.

RESULTS

ICC and SEM values showed excellent reliability for the PSFS scale, with a SDC of 1. A significant moderate correlation was found between the results of the PSFS and the HAL (r = .57, P < .001).

CONCLUSION

The PSFS is a reliable and valid scale to measure the functionality of people with haemophilia.

Measurement Properties of the Patient-Specific Functional Scale and Its Current Uses: An Updated Systematic Review of 57 Studies Using COSMIN Guidelines

OBJECTIVE

To systematically review measurement properties, including acceptability, feasibility, and interpretability, and current uses of the Patient-Specific Functional Scale (PSFS).

DESIGN

Systematic review of a patient-reported outcome measure using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) guidelines.

LITERATURE SEARCH

We searched 11 databases from January 2010 to July 2020 for articles on measurement properties or use of PSFS.

STUDY SELECTION CRITERIA

Published primary articles without language restrictions.

DATA SYNTHESIS

Two independent reviewers screened all records, extracted data, and performed risk of bias assessments using COSMIN guidelines. We qualitatively synthesized findings for each measurement property in musculoskeletal and nonmusculoskeletal conditions, and 2 reviewers independently performed Grading of Recommendations Assessment, Development and Evaluation assessments. This study was preregistered with the Open Science Framework (https://doi.org/10.17605/OSF.IO/42UZT).

RESULTS

Of the 985 articles screened, we included 57 articles on measurement properties and 255 articles on the use of PSFS. The PSFS had sufficient test-retest reliability in musculoskeletal (22 studies, 845 participants, low-to-moderate certainty) and nonmusculoskeletal conditions (6 studies, 197 participants, very low certainty), insufficient construct validity as a measure of physical function (21 studies, 2 945 participants, low-to-moderate certainty), and sufficient responsiveness (32 studies, 13 770 participants, moderate-to-high certainty). The standard error of measurement ranged from 0.35 to 1.5. The PSFS was used in 87 unique health conditions, some without prior evidence of validity.

CONCLUSION

The PSFS is an easy-to-use, reliable, and responsive scale in numerous musculoskeletal conditions, but the construct validity of PSFS remains uncertain. Further study of the measurement properties of the PSFS in nonmusculoskeletal conditions is necessary before clinical use. J Orthop Sports Phys Ther 2022;52(5):262-275.

Pain self‐management intervention supports successful attainment of self‐selected rehabilitation goals—secondary analysis of a randomized controlled trial

Objectives

(i) Describe patients' self‐selected activity‐related rehabilitation goals, and (ii) compare attainment of these rehabilitation goals among people with persistent tension‐type neck pain receiving a group‐based pain and stress self‐management intervention (PASS) or individual physiotherapy (IPT).

Methods

Before intervention and random allocation to PASS or IPT, 156 people (PASS n = 77, IPT n = 79), listed three self‐selected activity‐related rehabilitation goals by use of the Patient Goal Priority Questionnaire (PGPQ). For each activity goal, participants rated limitations in activity performance, self‐efficacy and fear of activity performance, readiness to change to improve performance, and expectations of future activity performance. At follow‐ups (10 weeks, 20 weeks, 1 year and 2 years after inclusion), participants also responded to a question on changes made to improve activity performance. Mann–Whitney U test was used to evaluate between‐group differences.

Results

There were between‐group differences in favour of PASS in the attainment of self‐selected rehabilitation goals with regard to activity limitations and satisfaction with activity performance at all follow‐ups.

Conclusions

PASS was more successful than IPT for the attainment of self‐selected rehabilitation goals, improvements in activity limitations and satisfaction with activity performance as measured by PGPQ. The PASS programme emphasized the importance of applying active pain‐ and stress‐coping techniques in personal ‘risk situations’ for pain flare‐ups, which appear to support people with persistent tension‐type neck pain to make changes in their lives to improve activity performance.

Patient or Public Contribution

Patient engagement in rehabilitation by self‐selected goals was investigated, but patients were not involved in the design or conduct of the study.

Bridging troubled water ‐ exploring improvement and patients' experiences using patient‐reported outcome measures in physiotherapy: A mixed‐method study

Background and Aims

Increased use of patient‐reported outcomes in health care has been emphasized. Our aim was to use the Patient‐Specific Functional Scale (PSFS) to examine improvement in neck pain patients' activity limitations during physiotherapy treatment, with the purpose to explore the patients' experiences of using PSFS. The study illuminates whether and how PSFS can be useful in clinical physiotherapy.

Methods

Six patients participated. A mixed‐method study design was applied, triangulating ontological perspectives of realism and phenomenology, quantitative and qualitative methods. Single Subject Experimental Design with PSFS as outcome measure examined changes over time and phenomenological interviews examined its meaningfulness for patients. Patients defined their personal activity limitations due to neck pain and scored difficulties several times, during the physiotherapy treatment period, using PSFS. We used visual analyses of the quantitative data and thematic analyses of the qualitative data. Integration and combination of the results from the two designs are presented in the discussion.

Results

In the quantitative analyses, PSFS showed improvement in most activity limitations during treatment. The qualitative analyses revealed that using PSFS required the patient to engage in different bodily awareness processes and handle the dilemma of a possible double function of scoring chosen activities. The mixed findings revealed improved functionality and that the context and the interaction between patient and therapist have a significant influence on the assessment process.

Conclusions

To be able to improve the utilization of PSFS, communication between patients and physiotherapists is of vital importance. When using PSFS, physiotherapists should direct their attention to the importance of interaction as always present and vital in assessments.

The Patient-Rated Elbow Evaluation and the American Shoulder and Elbow Surgeons-Elbow form capture aspects of functioning that are important to patients with elbow injuries

STUDY DESIGN

This is a cross-sectional study.

INTRODUCTION

The Patient-Rated Elbow Evaluation (PREE) and the self-report section of the American Shoulder Elbow Surgeons-elbow form (pASES-e) are two important elbow-specific self-report measures used in routine clinical practice.

PURPOSE OF THE STUDY

To use the International Classification of Functioning Disability and Health (ICF) to link aspects of functioning that are reported using the Patient-Specific Functional Scale by a cohort of patients with elbow disorders and compare it to the content of the PREE and the pASES-e.

METHODS

One hundred patients with a variety of elbow disorders (mean age and SD 53.88 (14.51); M: F 48: 52) were recruited from the Roth-McFarlane Hand and Upper Limb Centre. They self-reported important aspects of functioning using the Patient-Specific Functional Scale. These concerns were linked to the ICF using formal linking procedures. These ICF categories were compared to the categories related to the PREE and the pASES-e. Linking was carried out by two independent raters, and agreement was calculated using percentage agreement.

RESULTS

A total of 423 self-reported functional activities were linked to 25 second-level ICF categories from the activity and participation domain. Commonly reported activities were D640 doing housework (52%); D540 dressing (47%); and D475 driving (35%). PREE had better coverage of the patient concerns (71%) than pASES-e (50%). D475-driving (35%) and D440-fine hand use (24%) were the 2 major categories that were not captured by the questionnaires. Agreement between the raters was 90.5%.

DISCUSSION

This study established that the PREE and the pASES-e were able to capture aspects of functioning important to patients and that align with the ICF, with this happening to a greater extent on the PREE than the pASES-e. Because all patients reported concerns from the activity and participation section ('d' categories) of the ICF, this validated that these PROMs measure this conceptual domain.

CONCLUSION

The PREE provided more comprehensive coverage of patients' functional concerns than the pASES-e.

Maintenance of physical activity level, functioning and health after non-pharmacological treatment of pelvic girdle pain with either transcutaneous electrical nerve stimulation or acupuncture: a randomised controlled trial

OBJECTIVE

To investigate if there are differences between acupuncture and transcutaneous electrical nerve stimulation (TENS) as treatment for pelvic girdle pain (PGP) in pregnancy in order to manage pain and thus maintain health and functioning in daily activities and physical activity (PA).

DESIGN

Randomised controlled trial.

SETTING AND PARTICIPANTS

Pregnant women (n=113) with clinically verified PGP in gestational weeks 12-28, recruited from maternity healthcare centres, randomised (1:1) into two groups.

EXCLUSION CRITERIA

any obstetrical complication, systemic disease or previous disorder that could contradict tests or treatment.

INTERVENTIONS

The intervention consisted of either 10 acupuncture sessions (two sessions per week) provided by a physiotherapist or daily home-based TENS during 5 weeks.

PRIMARY OUTCOME VARIABLES

Disability (Oswestry Disability Index), functioning (Patient Specific Functional Scale), work ability (Work Ability Index) and PA-level according to general recommendations.

SECONDARY OUTCOME VARIABLES

Functioning related to PGP (Pelvic Girdle Questionnaire), evening pain intensity (Numeric Rating Scale, NRS), concern about pain (NRS), health (EuroQoL 5-dimension), symptoms of depression/catastrophising (Edinburgh Postnatal Depression Scale/Coping Strategies Questionnaire).

RESULTS

No mean differences were detected between the groups. Both groups managed to preserve their functioning and PA level at follow-up. This may be due to significantly (p<0.05) reduced within groups evening pain intensity; acupuncture -0.96 (95% CI -1.91 to -0.01; p=0.049), TENS -1.29 (95% CI -2.13 to -0.44; p=0.003) and concern about pain; acupuncture -1.44 (95% CI -2.31 to -0.57; p=0.0012), TENS -1.99 (95% CI -2.81 to -1.17; p<0.0001). The acupuncture group showed an improvement in functioning at follow-up; 0.82 (95% CI 0.01 to 1.63; p=0.048) CONCLUSION: Treating PGP with acupuncture or TENS resulted in maintenance of functioning and physical activity and also less pain and concern about pain. Either intervention could be recommended as a non-pharmacological alternative for pain relief and may enable pregnant women to stay active.

A framework to make PROMs relevant to patients: qualitative study of communication preferences of PROMs

PURPOSE

Patient-reported outcome measures are tools for evaluating symptoms, magnitude of limitations, baseline health status, and outcomes from the patient's perspective. Healthcare professional organizations and payers increasingly recommend PROMs for clinical care, but there lacks guidance regarding effective communication of PROMs with orthopedic surgery patients. This qualitative study aimed to identify (1) patient attitudes toward the use and communication of PROMs, and (2) what patients feel are the most relevant or important aspects of PROM results to discuss with their physicians.

METHODS

Participants were recruited from a multispeciality orthopedic clinic. Three PROMs: the EuroQol-5 Dimension, the Patient-Specific Functional Scale, and the Patient-Reported Outcome Measurement Information System Physical Function Computer Adaptive Test were shown and a semi-structured interview was conducted to elicit PROMs attitudes and preferences. Interviews were transcribed and inductive-deductively coded. Coded excerpts were aggregated to (1) identify major themes and (2) analyze how themes interacted.

RESULT

Three themes emerged: (1) Beliefs toward the purpose of PROMs, (2) PROMs as a reflection of self, and (3) PROMs to facilitate communication and guide healthcare decisions. These themes informed a framework outlining the patient perspective on communicating PROMs during clinical care.

CONCLUSION

Patient attitudes toward the use and communication of PROMs start with the incorporation of patient beliefs, which can facilitate or act as a barrier to engagement. Patients should ideally believe that PROMs are an accurate reflection of personal health state before incorporation into care. Clinicians should endeavor to communicate the purpose of a chosen PROM in line with a patient's unique needs and what they feel is most relevant to their own care. Aspects of PROMs results which may be helpful to address include providing context for what scores mean and how they are calculated, and using scores as a way to weigh risks and benefits of treatment and tracking progress over time. Future research can focus on the effect of communication strategies on patient outcomes and engagement in care.

Clinical characteristics differ between patients with non-traumatic neck pain, patients with whiplash-associated disorders, and pain-free individuals

BackgroundEvidence is lacking to what extent patients with Whiplash-Associated Disorders (WAD), those with non-traumatic neck pain (NTNP), and pain-free individuals differ regarding type and severity of impairments, disability, and psychological factors.Objective To compare clinical characteristics between patients with WAD, with NTNP, and pain-free individuals in primary care physiotherapy. Additionally, differences between patient groups for both acute and chronic symptoms were assessed.MethodA cross-sectional study was conducted including 168 patients with WAD, 336 matched patients with NTNP, and 336 pain-free individuals. Differences and prevalence rates were calculated for pain intensity, pain distribution, cervical range of motion, neck flexor muscle endurance, self-reported disability, and psychological factors.Results Patients with WAD had higher pain intensity (median 6/10 vs. 5/10 p<.01), had a wider distribution of their neck pain (p=.02), more restricted cervical flexion-extension (-11.9°) and rotation (-12.4°), less muscle endurance (-5.5 seconds), and more disability (+14.0%), compared to patients with NTNP. More patients with WAD reported low back pain (+9.5%) and headache (+12.2%) as musculoskeletal comorbidities. Regarding anxiety, depression, and stress, most patients (>83%) scored in the normal range. No significant differences between the patient groups were observed (p>.16). Both patient groups scored significantly worse than pain-free individuals on all characteristics. Patients with WAD and NTNP experienced different types of activity limitations and participation restrictions.ConclusionWAD is a more severe condition than NTNP and should be considered a separate subgroup. A different approach in clinical practice and research is required for WAD and NTNP.

The Patient-Reported Outcome Measures Used with Low Back Pain and the Attitude of Primary Healthcare Practitioners in Saudi Arabia toward Them

Background and objectives: The use of appropriate outcome measures can help guide multidimensional low back pain (LBP) management, elucidate the efficacy/effectiveness of interventions, and inform clinicians when selected targets have been achieved and this can be used for educational or research purposes. Aim: This study aimed to explore and describe the use, attitudes, knowledge, and beliefs regarding patient-reported outcome measures used by healthcare practitioners practising in Saudi Arabia who are frequently involved in the healthcare of individuals with LBP. Materials and Methods: A cross-sectional design was undertaken using a web-based survey. An electronic invitation to participate was sent to primary care physicians and physical therapists practising in Saudi Arabia. The survey included three sections: demographic data, a list of the most commonly used patient-reported outcome measures with LBP patients, and statements regarding attitudes, knowledge, and beliefs about outcome measures. Results: A total of 156 practitioners participated: 45 primary care physicians and 111 physical therapists. The numeric pain rating and visual analogue scales were the outcome measures most frequently reported as being often used by both primary care physicians and physical therapists. The majority of participants reported often using 1-2 patient reported outcome measures (PROMs). While most participants indicated that they were confident at selecting the most appropriate PROM, fewer were familiar with the concept of the minimally important clinical difference. A lack of Arabic versions of PROMs was reported as a barrier to using them to assess pain. Conclusions: This study shows that, although primary care physicians and physical therapists in Saudi Arabia frequently use patient-reported outcome measures in their clinical management of patients with LBP, there is a noticeable gap in the knowledge and use of the multidimensional outcome measures for LBP management among the participants. This highlights a need for professional training on the use of standardised outcome measures related to LBP.

Reliability, validity and discriminability of patient reported outcomes for non-specific low back pain in a nationwide physical therapy registry: A retrospective observational cohort study

BACKGROUND

A national clinical registry was established in the Netherlands containing data directly sampled from electronic health record systems of physical therapists (PTs). This registry aims to evaluate the potential of patient reported outcome measures (PROMs) to develop quality indicators (QIs) in physical therapy care.

PURPOSE

To test to what extent the collected PROM data are reliable, valid and discriminatory between practices in measuring outcomes of patients with non-specific low back pain (NSLBP).

METHODS

In this retrospective cohort study 865 PT practices with 6,560 PTs voluntarily collected PROM data of patients with NSLBP, using the Quebec Back Pain Disability Scale (QBPDS), the Numeric Pain Rating Scale (NPRS) and the Patient Specific Functioning Scale (PSFS). Reliability was determined by analysing the completeness of the dataset, the comparability by using national reference data, and through checking selection bias in the included patients. Validity was tested using the known-groups contrast between patients with (sub)acute vs. chronic NSLBP. To determine discriminative ability of outcomes between PT practices, case-mix corrected hierarchical multilevel analyses were performed.

RESULTS

Reliability was sufficient by confirming fifteen of the sixteen hypotheses: 59% of all patients opted in for data analysis, 42% of these included patients showed repeated measurement, comparing with reference data and potential selection bias showed < 5% between group differences, while differences between (sub)acute and chronic NSLB-groups were significantly larger than 5% (less treatment sessions, lager differences in outcomes in (sub)acute NSLB patients). In addition, all nine adjusted hierarchical multilevel models confirm that the collected dataset on outcomes in PT care is able to discriminate between practices using PROM results of patients with NSLBP (ICC-scores range 0.11-0.21).

LIMITATIONS

Although we have shown the reliability, validity and discriminative ability of the dataset in the quest to develop QIs, we are aware that reducing missing values in patient records and the selective participation of PTs that belong to the innovators needs attention in the next stages of implementation to avoid bias in the results.

CONCLUSION

PROMs of patients with NSLBP collected in the national clinical registry of KNGF are reliable, valid and able to discriminate between primary care PT practices.

Exploring the Perth Hamstring Assessment Tool and Lower Extremity Functional Scale in a Proximal Hamstring Avulsion Cohort: A Cross-sectional Study

BACKGROUND

The goal of treatment for a proximal hamstring avulsion (PHA) is an objectively restored muscle and a subjectively satisfied, pain-free patient at follow-up. Different self-reported and performance-based outcome measures have been used to evaluate recovery, but their validity is poorly investigated.

PURPOSE

To investigate (1) the correlation between the commonly used self-reported outcome measurements, the Perth Hamstring Assessment Tool (PHAT) and the Lower Extremity Functional Scale (LEFS); (2) to what extent these scores can be explained by physical dysfunction as measured by performance-based tests; (3) whether performance-based tests can discriminate between the injured and uninjured extremity; and (4) which activity limitations are perceived by patients several years after the injury.

STUDY DESIGN

Cohort study (Diagnosis); Level of evidence, 3.

METHODS

We included a consecutive series of patients treated for or diagnosed with PHA in our department between 2007 and 2016 having at least 2 tendons avulsed from the ischial tuberosity. Participants attended 2 study visits, answered questionnaires (PHAT, LEFS, and Patient-Specific Functional Scale [PSFS]), and performed physical performance-based tests (single-leg hop tests, single-step down test, and isometric and isokinetic strength tests).

RESULTS

A total of 50 patients were included (26 men [52%], 24 women [48%]; mean age, 50.9 years [SD, 9.8 years]). The mean follow-up time was 5.5 years (SD, 2.7 years), and 74% had been surgically treated. The correlation between PHAT and LEFS was strong (r = 0.832) and statistically significant (P < .001). Seven of the performance-based tests exhibited a statistically significant but weak correlation with LEFS (0.340-0.488) and 3 of the tests to PHAT (-0.304 to 0.406). However, only peak torque could significantly discriminate between the extremities. The activity limitation most commonly mentioned in PSFS was running (16 patients [32%]).

CONCLUSION

Although PHAT and LEFS correlated strongly, the correlations between functional tests and the patient-reported outcome scores were weak, and most functional tests failed to discriminate between the injured and uninjured lower extremity in patients with PHA 5 years after injury. In general, patients alleged few activity limitations, but running difficulty was a common sequela after PHA.

Clinical and radiographic outcomes using third-generation bioactive glass as a bone graft substitute for multi-level anterior cervical discectomy and fusion-a retrospective case series study

Background

Bioactive glasses have unique bone forming properties that have been used as a bone graft substitute for anterior cervical discectomy and fusions (ACDFs). Bone graft substitutes are used for achieving fusion while simultaneously avoiding donor site morbidity of iliac crest autograft. In this study, our principal intention is to assess the clinical and radiographic outcomes in patients with multi-level cervical disc disease undergoing ACDF using a third-generation bioactive glass as a bone graft substitute.

Methods

A retrospective case series study was performed of patients who underwent primary multi-level instrumented fusions for degenerative cervical disc disease with bioactive glass bone graft substitute between May 2016 and December 2017 by a single fellowship-trained spine surgeon. All patients were treated with a porous PEEK interbody spacer and with a third-generation bioactive glass synthetic bone graft substitute. Patients were assessed pre-operatively, immediately following surgery, and at 3, 6, 12, and 24 months. Accepted standard outcome measures were applied to evaluate preoperative and postoperative metrics, including Visual Analog Scale neck pain and arm pain, and Neck Disability Index. Dynamic lateral radiographs were used to assess sagittal alignment, disc space height, arthrodesis status, osseous integration, and implant migration. Sagittal plane angulation was measured by Cobb's criteria.

Results

Thirty-nine patients underwent multi-level instrumented fusions: seventeen (43%) were two-level; 12 (31%) were three-level; 9 (23%) were four-level; and 1 (3%) was five-levels. All patients were followed for a minimum of 6 months for mean of 16.0 months (range, 6 to 36 months); none were lost to follow-up. Significant improvements from preoperative scores in Neck Disability Index scores as well as neck and arm visual analog scale pain scores were realized. All patients either maintained or improved their neurological status. Radiographically, all patients were fused by 6 months postoperatively and showed improvement in fusion segment lordosis (Pre-Post and Pre-Final P<0.001), C2-C7 lordosis angle (Pre-Post and Pre-Final P<0.001), T1 slope (Pre-Post P=0.01, Pre-Final P=0.07) and maintenance of disc height (Post-Final P=0.02). There were no adverse events, infections, or reoperations.

Conclusions

Third-generation bioactive glass synthetic graft is a viable alternative to allograft or autograft in the setting of multi-level instrumented fusions for achieving improved clinical and radiographic outcomes.

Trauma-focused cognitive behavioural therapy and exercise for chronic whiplash with comorbid posttraumatic stress disorder: a randomised controlled trial

ABSTRACT

Many people with chronic whiplash-associated disorders (WAD) have also symptoms of posttraumatic stress disorder (PTSD), but this is rarely considered in usual predominantly exercise-based interventions. We aimed to investigate the effectiveness of combined trauma-focused cognitive behavioural therapy (TF-CBT) and exercise compared with supportive therapy (ST) and exercise for people with chronic WAD and PTSD. A randomised controlled multicentre trial with concealed allocation, assessor blinding, and blinded analysis was conducted. One hundred three participants with chronic WAD (>3 months and <5 years, grade II) and PTSD were randomised to TF-CBT and exercise (n = 53) or ST and exercise (n = 50). Both interventions comprised 10 weeks of TF-CBT or ST, followed by 6 weeks of exercise. Outcomes were measured at baseline, 10, 16 weeks, 6, and 12 months after randomisation. Analysis was intention to treat using linear mixed models. There was no difference between the interventions on the primary outcome of neck pain-related disability at any time point. At 16 weeks, the treatment effect on the 0 to 100 Neck Disability Index was 0.59 (95% confidence interval [CI] 5.51 to -4.33), at 6 months 1.18 (95% CI 6.15 to -3.78), and at 12 months 1.85 (95% CI 6.81 to -3.11). In addition, there was no difference between the interventions for most secondary outcomes at any time. Exceptions were in favour of TF-CBT and exercise, where improvements in PTSD symptoms were found at 16 weeks. From 16 weeks onwards, both groups achieved a clinically important improvement in neck pain-related disability. However, both groups remained moderately disabled.

Translation, cross-cultural adaptation and validation of the Brazilian Portuguese version of the Victorian Institute of Sports Assessment for Gluteal Tendinopathy patient reported-outcome measure (VISA-G.BR)

BACKGROUND

Different outcome measures can be used to assess pain and disability in individuals with Greater Trochanteric Pain Syndrome (GTPS), including the Victorian Institute of Sports Assessment for Gluteal Tendinopathy (VISA-G), Oswestry Disability Index (ODI), Patient Specific Functional Scale (PSFS) and Global Perceived Effect (GPE).

OBJECTIVE

To translate, cross-culturally adapt and validate VISA-G to Brazilian Portuguese and to evaluate the measurement properties of the VISA-G.BR, ODI, GPE, and PSFS in individuals with GTPS.

DESIGN

This is a longitudinal clinimetric study.

METHODS

Sixty-eight individuals with GTPS participated in this study. The questionnaires VISA-G.BR, ODI, PSFS, and GPE were administered to participants at the initial assessment, 24-48 h and 30 days after the initial assessment. Internal consistency and construct validity for the VISA-G.BR were assessed. Reliability, agreement, ceiling and floor effect, and responsiveness were described for all instruments.

RESULTS

The Cronbach Alpha for internal consistency value for VISA-G.BR was 0.65. The construct validity analysis showed a strong correlation value between ODI and VISA-G.BR (r = -0.77). The agreement analysis performed for all questionnaires showed standard error of measurement values ranging from 0.64 (PSFS) to 4.2 (VISA-G.BR). GPE scale had a floor effect. The responsiveness analysis performed for all questionnaires showed low values of effect size ranging from -0.07 to 0.3.

CONCLUSION

The VISA-G.BR is a valid and reliable instrument to assess the disability of individuals with GTPS. The ODI and PSFS instruments can also be used in the evaluation of this population.

Cross-cultural adaptation and measurement properties of the Arabic version of the Patient-Specific Functional Scale in patients with lower extremity musculoskeletal disorders

PURPOSE

To cross-culturally adapt the Patient-Specific Functional Scale (PSFS) into Arabic language and to examine its measurement properties in patients with lower extremity musculoskeletal disorders.

MATERIALS AND METHODS

The original English version of the PSFS was cross-culturally adapted into modern standard Arabic language following Beaton's guidelines. Patients with lower extremity musculoskeletal disorders (N = 116) were recruited to examine the test-retest reliability, measurement error, floor and ceiling effects, and construct validity of the Arabic PSFS. Construct validity was tested by examining eight predefined correlational hypotheses.

RESULTS

Participants in the current study indicated that the Arabic PSFS was clear and understandable. The Arabic PSFS had very good test-retest reliability (ICC = 0.86) with no floor or ceiling issues. The standard error of measurement and the minimal detectable change of the Arabic PSFS were 0.64 and 1.49 points respectively indicating acceptable measurement error. The majority of the predefined construct validity hypotheses (75%) were supported by the results justifying the construct validity of the Arabic PSFS.

CONCLUSIONS

The Arabic PSFS is a comprehensible and easy to use measure. The Arabic PSFS has very good test-retest reliability, acceptable measurement error, and evidence supporting its construct validity as measure of activity limitation in patients with lower extremity musculoskeletal disorders.Implications for rehabilitationRehabilitation specialist can confidently interpret patient's score in the Arabic PSFS to represent the extent of activity limitation.Patients with unchanged clinical status will have similar scores in the Arabic PSFS with repeated administrations of the scale over time.The Arabic PSFS can be used in daily clinical practice and in research studies to measure activity limitation in Arabic-speakers with lower extremity musculoskeletal disorders.The Arabic PSFS enables rehabilitation specialist to quantify activity limitation in a way that is relevant to the culture and life style of Arabic-speakers.

Adherence to self-managed exercises for patients with persistent subacromial pain: the Ad-Shoulder feasibility study

BACKGROUND

Exercise is recommended for patients with subacromial pain. It has been suggested that good exercise adherence improves clinical outcomes. Despite this, little attention has been paid to the need for behavioural frameworks to enhance adherence to home exercise programmes for patients with subacromial pain.

METHODS

A feasibility study with pre-post design was used. Participants aged > 18 years, with subacromial pain, who had received conservative treatment during the past 6 months, were recruited. The Ad-Shoulder intervention consisted of 1-5 individual sessions provided over 3 months and was based on 5 self-management skills, which aimed to enhance the patients' self-efficacy and adherence to self-managed exercises. The primary objectives were assessed according to predefined progression criteria: (1) the recruitment rate (10 patients enrolled within 12 weeks), (2) follow-up rate (≥ 80% on all self-reported measures), (3) objective physical activity measures (≥ 80% of participants would contribute valid data at each time point), (4) adherence with the self-managed exercises (≥ 80% of the participants would adhere to ≥ 80% of the assigned home exercise programme), (5) fidelity of the delivery of the intervention (the therapists delivered the intervention according to the protocol) and (6) adverse events (< 30% would report adverse events (including mild)). The results were reported using descriptive statistics.

RESULTS

Eleven patients were recruited during 16 weeks. Ten patients completed the self-reported measures at baseline and week 12. Objective physical activity measures were successfully obtained for 100% (11/11) at baseline, 64% (7/11) at week six and 82% at week 12. Fifty-five percent (6/11) of the participants satisfactorily completed at least 80% of their home exercise programme. All sessions were delivered according to the protocol. None of the patients reported any adverse events.

CONCLUSIONS

Objective physical activity data measures at baseline and week 12, follow-up, the physiotherapists' fidelity to the intervention and adverse events met our pre-specified progression criteria. Recruitment and adherence to the self-managed exercise programme were both below the anticipated level. Further intervention development is necessary to understand whether adherence to the self-managed exercises could be enhanced and additional methods of recruitment would need to be considered, including additional recruitment sites, in any planning for a future main trial.

Randomised, cross-over trial on the effect of isotonic and isometric exercise on pain and strength in proximal hamstring tendinopathy: trial protocol

Background

Proximal hamstring tendinopathy (PHT) is a condition that occurs at all ages and levels of sporting participation. Presenting as localised lower buttock pain with tasks such as squatting and sitting, it can cause disability with sport, work and other activities of daily living. Recent research has investigated the effect of isometric exercise on pain and strength with a range of tendinopathies but there are no published studies on PHT. This protocol paper details a study investigating the effectiveness of isometric compared with isotonic exercise on pain and strength in people with PHT.

Methods/Design

The study is a prospective, cross-over randomised controlled trial (RCT). Twenty participants with PHT, recruited from the local community and sporting clubs will be recruited for the study. Participants will receive one session of isotonic hamstring strength exercises and one session of isometric hamstring exercise, with random allocation to the order of intervention.

Primary outcomes will be hamstring strength measured with a dynamometer and pain with a functional task, assessed immediately following and 45 min after intervention. A secondary outcome will be pain with sitting assessed 24 hours after intervention.

The effect of isotonic versus isometric exercise on hamstring pain and strength will be determined using a repeated measures linear mixed model. Further analyses will determine the proportion of patients with clinically important pain and strength improvements, using relative risks, χ² testing and number needed to treat.

Discussion

This RCT protocol will investigate the effect of isometric compared with isotonic exercise for PHT.

Does Neck Disability Index Correlate With 12-Month Satisfaction After Elective Surgery for Cervical Radiculopathy? Results From a National Spine Registry

BACKGROUND

Modern healthcare reforms focus on identifying and measuring the quality and value of care. Patient satisfaction is particularly important in the management of degenerative cervical radiculopathy (DCR) since it leads to significant neck pain and disability primarily affecting the patients' quality of life.

OBJECTIVE

To determine the association of baseline and 12-mo Neck Disability Index (NDI) with patient satisfaction after elective surgery for DCR.

METHODS

The Quality Outcomes Database cervical module was queried for patients who underwent elective surgery for DCR. A multivariable proportional odds regression model was fitted with 12-mo satisfaction as the outcome. The covariates for this model included patients' demographics, surgical characteristics, and baseline and 12-mo patient reported outcomes (PROs). Wald-statistics were calculated to determine the relative importance of each independent variable for 12-mo patient satisfaction.

RESULTS

The analysis included 2206 patients who underwent elective surgery for DCR. In multivariable analysis, after adjusting for baseline and surgery specific variables, the 12-mo NDI score showed the highest association with 12-mo satisfaction (Waldχ2-df = 99.17, 58.1% of total χ2). The level of satisfaction increases with decrease in 12-mo NDI score regardless of the baseline NDI score.

CONCLUSION

Our study identifies 12-mo NDI score as a very influential driver of 12-mo patient satisfaction after surgery for DCR. In addition, there are lesser contributions from other 12-mo PROs, baseline Numeric Rating Scale for arm pain and American Society of Anesthesiologists (ASA) grade. The baseline level of disability was found to be irrelevant to patients. They seemed to only value their current level of disability, compared to baseline, in rating satisfaction with surgical outcome.

Invariance Testing of the Disablement in the Physically Active Scale

CONTEXT

The increased emphasis on implementing evidence-based practice has reinforced the need to more accurately assess patient improvement. Psychometrically sound, patient-reported outcome measures are essential for evaluating patient care. A patient-reported outcome instrument that may be useful for clinicians is the Disablement in the Physically Active Scale (DPAS). Before adopting this scale, however, researchers must evaluate its psychometric properties, particularly across subpopulations.

OBJECTIVE

To evaluate the psychometric properties of the DPAS in a large sample using confirmatory factor analysis procedures and assess structural invariance of the scale across sex, age, injury status, and athletic status groups.

DESIGN

Observational study.

SETTING

Twenty-two clinical sites.

PATIENTS OR OTHER PARTICIPANTS

Of 1445 physically active individuals recruited from multiple athletic training clinical sites, data from 1276 were included in the analysis. Respondents were either healthy or experiencing an acute, subacute, or persistent musculoskeletal injury.

MAIN OUTCOME MEASURE(S)

A confirmatory factor analysis was performed on the full sample, and multigroup invariance testing was conducted to assess differences across sex, age, injury status, and athletic status. Given the poor model fit, alternate model generation was used to identify a more parsimonious factor structure.

RESULTS

The DPAS did not meet contemporary fit index recommendations or the criteria to demonstrate structural invariance. We identified an 8-item model that met the model fit recommendations using alternate model generation.

CONCLUSIONS

The 16-item DPAS did not meet the model fit recommendations and may not be the most parsimonious or reliable measure for assessing disablement and quality of life. Use of the 16-item DPAS across subpopulations of interest is not recommended. More examination involving a true cross-validation sample should be completed on the 8-item DPAS before this scale is adopted in research and practice.

Effect of Neural Mobilization on Nerve-Related Neck and Arm Pain: A Randomized Controlled Trial

Purpose: Neural mobilization (NM) is often used to treat nerve-related conditions, and its use is reasonable with nerve-related neck and arm pain (NNAP). The aims of this study were to establish the effect of NM on the pain, function, and quality of life (QOL) of patients with NNAP and to establish whether high catastrophizing and neuropathic pain influence treatment outcomes. Method: A randomized controlled trial compared a usual-care (UC; n = 26) group, who received cervical and thoracic mobilization, exercises, and advice, with an intervention (UCNM; n = 60) group, who received the same treatment but with the addition of NM. Soft tissue mobilization along the tract of the nerve was used as the NM technique. The primary outcomes were pain intensity (rated on the Numerical Pain Rating Scale), function (Patient-Specific Functional Scale), and QOL (EuroQol-5D) at 3 weeks, 6 weeks, 6 months, and 12 months. The secondary outcomes were the presence of neuropathic pain (using the Neuropathic Diagnostic Questionnaire) and catastrophizing (Pain Catastrophising Scale). Results: Both groups improved in terms of pain, function, and QOL over the 12-month period (p < 0.05). No between-groups differences were found at 12 months, but the UCNM group had significantly less pain at 6 months (p = 0.03). Patients who still presented with neuropathic pain (p < 0.001) and high pain catastrophizing (p = 0.02) at 6- and 12-mo follow-ups had more pain. Conclusions: Both groups had similar improvements in function and QOL at 12-month follow-up. The UCNM group had significantly less pain at 6-month follow-up and a lower mean pain rating at 12-month follow-up, although the difference between groups was not significant. Neuropathic pain is common among this population and, where it persisted, patients had more pain and functional limitations at 12-mo follow-up.

Cervical spine thrust and non-thrust mobilization for the management of recalcitrant C6 paresthesias associated with a cervical radiculopathy: a case report

BACKGROUND

The conservative management of cervical radiculopathy is supported by moderate evidence to include interventions such as manual therapy, traction, and therapeutic exercise. There is sparse evidence, however, to support specific manual therapy techniques, particularly thrust manipulation.

CASE DESCRIPTION

A 35-year-old male presented to physical therapy with a clinical diagnosis of cervical radiculopathy. He complained of neck and upper arm pain with 1st and 2nd digit paresthesias. He was initially managed with repeated movements that restored the cervical range of motion and centralized neck and upper arm pain. Non-thrust upslope joint mobilizations resulted in improved sensation detection in the hand, but the paresthesias did not completely resolve. Immediately following cervical spine upslope thrust manipulation, symptoms fully resolved. Outcomes: The patient fully returned to prior level of function. His DASH score reduced from 40/100 to 2/100, PSFS improved from 1.66/10 to 9.66/10, and he reported to be 'a great deal better' on the GROC.

DISCUSSION

This case demonstrates the safe and effective utilization of cervical spine thrust manipulation and non-thrust mobilization in the management of a patient with cervical radiculopathy with lingering paresthesias in the distal upper extremity.

Defining threshold values on the neck disability index corresponding to a patient acceptable symptom state in patients undergoing elective surgery for degenerative disorders of the cervical spine

BACKGROUND CONTEXT

The patient acceptable symptom state (PASS) has emerged as a novel tool for interpreting patient-reported outcomes. While the minimal clinically important difference values for various spine outcome instruments have been defined, little is known about the PASS thresholds for these measures.

PURPOSE

To define threshold values on the neck disability index (NDI) corresponding to a PASS in patients undergoing surgery for degenerative disorders of the cervical spine.

STUDY DESIGN

Retrospective review of prospectively collected registry data.

PATIENT SAMPLE

The sample includes 613 patients who underwent anterior cervical discectomy and fusion for degenerative spine conditions between 2005 and 2014.

OUTCOME MEASURES

The main outcome measure was the NDI. The PASS anchor question was adapted from the NASS questionnaire, "How would you rate the overall results of your treatment?" and the validation question was adapted from the AAOS cervical spine questionnaire, "Would you have the same treatment again if you had the same condition?"

METHODS

Patients were assessed preoperatively, 6 months and 2 years postoperatively using the NDI. Responses to the anchor question were dichotomized and used as the external criterion in receiver operating characteristics analysis to define thresholds on the NDI that corresponded to a PASS at 2 years postoperatively. Sensitivity analyses were carried out for various subgroups (age, gender, BMI, comorbidity status), baseline NDI (tertiles), time of follow-up (6 months and 2 years) and an alternate definition of PASS.

RESULTS

Of the 613 patients, 503 (82%) completed 2-year follow-up, of which, 81% reported their current state as acceptable. The areas under the curve (AUC) for the receiver operating characteristics were 0.75 to 0.89 for all analyses, indicating a good ability of the NDI to discriminate between attaining a satisfactory state or not. The PASS threshold was ≤15 points at 6 months (AUC 0.81, sensitivity 73%, specificity 79%) and ≤17 points at 2 years (AUC 0.80, sensitivity 86%, specificity 65%). Sensitivity analyses revealed that the 17-point threshold on the NDI was robust. PASS responders were approximately 12 times more likely to be satisfied (adjusted odds ratio 12.11, 95% confidence intervals 6.96-21.07) and 6 times more willing to undergo surgery again (adjusted odds ratio 6.12, 95% confidence intervals 3.47-10.80) compared to nonresponders.

CONCLUSIONS

Patients with a NDI of ≤17 consider their postoperative symptom state to be acceptable. This PASS threshold can be used alongside the minimal clinically important difference when defining treatment success in spine outcomes studies. At the individual level, this threshold provides clinically relevant benchmarks for surgeons when assessing a patient's postoperative recovery.

A comparison study between hybrid surgery and anterior cervical discectomy and fusion for the treatment of multilevel cervical spondylosis

AIMS

Whether to perform hybrid surgery (HS) in contrast to anterior cervical discectomy and fusion (ACDF) when treating patients with multilevel cervical disc degeneration remains a controversial subject. To resolve this we have undertaken a meta-analysis comparing the outcomes from HS with ACDF in this condition.

METHODS

Seven databases were searched for studies of HS and ACDF from inception of the study to 1 September 2019. Both random-effects and fixed-effects models were used to evaluate the overall effect of the C2-C7 range of motion (ROM), ROM of superior/inferior adjacent levels, adjacent segment degeneration (ASD), heterotopic ossification (HO), complications, neck disability index (NDI) score, visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, Odom's criteria, blood loss, and operating and hospitalization time. To obtain more credible results contour-enhanced funnel plots, Egger's and Begg's tests, meta-regression, and sensitivity analyses were performed.

RESULTS

In total, 17 studies involving 861 patients were included in the analysis. HS was found to be superior to ACDF in maintaining C2-C7 ROM and ROM of superior/inferior adjacent levels, but HS did not reduce the incidence of associated level ASD. Also, HS did not cause a higher rate of HO than ACDF. The frequency of complications was similar between the two techniques. HS failed to achieve more favourable outcomes than ACDF using the NDI, VAS, JOA, and Odom's scores. HS did not show any more advantages in operating or hospitalization time but did show reduction in blood loss.

CONCLUSION

Although HS maintained cervical kinetics, it failed to reduce the incidence of ASD. This finding differs from previous reports. Moreover, patients did not show more benefits from HS with respect to symptom improvement, prevention of complications, and clinical outcomes. Cite this article: Bone Joint J 2020;102-B(8):981-996.

Movement, posture and low back pain. How do they relate? A replicated single-case design in 12 people with persistent, disabling low back pain

BACKGROUND

Movement and posture are commonly believed to relate to non-specific low back pain (NSLBP). While people with NSLBP appear to move and posture themselves differently from those without NSLBP, changes in movement and posture infrequently relate to improvements in NSLBP when analysed at a group-level. Additionally, little is known about how movement or posture change when clinical outcome improves.

METHODS

Within-person relationships were investigated using a replicated, repeated measures, single-case design in 12 people with persistent, disabling NSLBP. Individually relevant movement and posture were captured using wearable sensors on up to 20 occasions over a 22-week period (5-week baseline, 12-week physiotherapy-led intervention, 5-week follow-up), while pain and activity limitation were collected concomitantly. A series of cross-correlation analyses estimated the presence, strength, and direction of relationships.

RESULTS

Many participants (n = 10/12) had strong (e.g. r = 0.91, p = <0.001) relationships between changes in movement or posture and changes in pain and activity limitation, while some showed no strong association. Where relationships were observed, clinical improvement predominantly (93% or 57/61 relationships) related to increased spinal movement range and velocity during forward bending and lifting, reduced lumbar muscle EMG activity at maximum voluntary flexion, and increased posterior-pelvic-tilt during sitting and standing.

CONCLUSION

Within-person changes to individually relevant movement and posture appear to often relate to clinical outcome, but not always. When changes were related, movement and posture appear to return towards being 'less protective', however causal directions remain unknown. Important activities, movements, and postural parameters varied across the participants, highlighting the potential importance of individualized management.

SIGNIFICANCE

Changes to individually relevant movement and posture appear to often relate to clinical outcome, but not always. Patient-specific activities, and movement or postural parameters that related to improved pain and activity limitation, varied across the 12 participants, highlighting the potential importance of individualised management. Where clinical improvements were related to changes in movement or posture, participants consistently returned towards being 'less protective' (increased range and speed of movement, increased posterior-pelvic-tilt during sitting and standing). Mechanisms and generalizability remain unclear.

Cross-cultural adaptation, reliability and validity of the Turkish version of Patient-Specific Functional Scale in patients with chronic neck pain

Background/aim

Current clinical guidelines recommend to use both clinical and self-reported measurements for evaluation of chronic neck pain. Among the self-reported outcomes, Neck disability index and patient-specific functional scale are the most widely used and recommended instruments. The purpose of our study was to determine the test-retest reliability and validity of patient-specific functional scale which was not validated in Turkish language previously.

Materials and methods

Translation and adaptation process had conducted according to the Beaton et al. Sociodemographic data, Turkish version of patient-specific functional scale and neck disability index were recorded at the initial assessment. Retest assessment was produced for reliability analyses and intraclass correlation coefficient (ICC3,2) was determined. The correlations between patient-specific functional scale and neck disability index and hypothesis testing were examined for the convergent and construct validity analysis.

Results

The final form was completed by 110 chronic neck pain patients (Male: 33; mean ages: 43.13 ± 13.75 years, Female: 77; mean ages: 44.45 ± 14.38). Test-retest reliability of patient-specific functional scale was found good level (ICC: 0.85). The relationship between patient-specific functional scale and neck disability index was found moderate level (P < 0.05, rho: –0.578). The median score of PSFS-T in the low disability group was significantly higher than the high disability group in the hypothesis testing of construct validity (P < 0.001).

Conclusion

The Turkish version of the patient-specific functional scale is a valid and reliable scale for evaluating functional status in patients with chronic neck pain.

The effects of integrating work-related factors and improving cooperation in musculoskeletal physical therapy practice: protocol for the 'WORK TO BE DONE' cluster randomised controlled trial

BACKGROUND

Musculoskeletal disorders (MSDs) are the primary cause of disability worldwide and a major societal burden. Recent qualitative research found that although a patient's work is considered important, physical therapists take work participation insufficiently into account as a determining factor in the treatment of patients with MSDs. Therefore, the aim of this study is to improve the effectiveness of physical therapy (in primary healthcare) with respect to the work participation of employees with MSDs by increasing the knowledge and skills of generalist physical therapists and by improving the collaboration between generalist physical therapists and physical therapists specialised in occupational health.

METHODS/DESIGN

This trial is a two-arm non-blinded cluster randomised controlled trial. Working patients with MSDs visiting a physical therapy practice are the target group. The control group will receive normal physical therapy treatment. The intervention group will receive treatment from a physical therapist with more knowledge about work-related factors and skills in terms of integrating work participation into the patients' care. Data are gathered at baseline (T0), at four months (T1) and eight months (T2) follow-up. Most outcomes will be assessed with validated patient-reported questionnaires. Primary outcomes are the limitations in specific work-related activities and pain during work. Secondary outcomes include limitations in general work-related activities, general pain, quality of life, presenteeism, sick leave (absenteeism), estimated risk for future work disability, work-related psychosocial risk factors, job performance, and work ability. Based on a sample size calculation we need to include 221 patients in each arm (442 in total). During data analysis, each outcome variable will be analysed independently at T1 and at T2 as a dependent variable using the study group as an independent variable. In addition to the quantitative evaluation, a process evaluation will be performed by interviewing physical therapists as well as patients.

DISCUSSION

The trial is expected to result in a more effective physical therapy process for working patients with MSDs. This will lead to a substantial reduction of costs: lower costs thanks to a more effective physical therapy process and lower costs due to less or shorter sick leave and decreased presenteeism.

Outcomes and value in elective cervical spine surgery: an introductory and practical narrative review

How we determine a successful clinical outcome and the value of a spine intervention are two major questions surrounding clinical spine research. Patient-reported outcomes (PROs), both LEGACY and Patient-Reported Outcomes Measurement Information System (PROMIS) measures, are becoming ubiquitous throughout the literature. Spine surgeons need a facile understanding of the financial landscape of their environment to influence change. In the current introductory, narrative review on outcomes and value in cervical spine surgery, we aim to: (I) define relevant outcome and cost terminology, (II) review recent cervical spine surgery literature, divided by specific pathology with a focus on LEGACY and PROMIS measures, and (III) discuss value and cost as they pertain to postoperative return to work and ambulatory surgery centers surgeries.

Patient-Reported Outcome Measures in Sports Medicine: A Concise Resource for Clinicians and Researchers

BACKGROUND

Despite the importance of assessing patient outcomes during patient care, current evidence suggests relatively limited use of patient-reported outcome measures (PROMs) by athletic trainers (ATs). Major barriers to PROM use include lack of knowledge, navigating the intricate process of assessing a wide variety of PROMs, and selecting the most appropriate PROM to use for care. A concise resource for ATs to consult when selecting and implementing PROMs may help facilitate the use of PROMs in athletic health care.

OBJECTIVE

To review the instrument essentials and clinical utility of PROMs used by ATs.

METHODS

We studied 11 lower extremity region-specific, 10 upper extremity region-specific, 6 generic, and 3 single-item PROMs based on the endorsement of at least 10% of ATs who use PROMs, as reported in a recent investigation of PROM use in athletic training. A literature search was conducted for each included PROM that focused on identifying and extracting components of the instrument essentials (ie, instrument development, reliability, validity, responsiveness and interpretability, and precision) and clinical utility (ie, acceptability, feasibility, and appropriateness). Through independent review and group consensus, we also classified each PROM question by International Classification of Functioning, Disability and Health domain and health-related quality-of-life dimensions.

KEY FINDINGS

The PROMs contained in this report generally possessed appropriate instrument essentials and clinical utility. Moreover, the PROMs generally emphasized body structure and function as well as the physical functioning of the patient. Athletic trainers aiming to assess patients via a whole-person approach may benefit from combining different PROMs for use in patient care to ensure broader attention to disablement health domains and health-related quality-of-life dimensions.

Cross-cultural adaptation, reliability, and validity of the Turkish version of the Neck OutcOme Score

Background/aim

This study aims to determine the validity and reliability of the Turkish version of the Neck OutcOme Score (NOOS).

Materials and methods

Two hundred eight patients suffering from nonspecific neck pain participated in the study. Test–retest reliability and internal consistency were assessed using intraclass correlation coefficients (2, 1) and Cronbach’s alpha, respectively. The dimensionality was investigated with the factor analysis. The construct validity was determined by testing whether the hypothesis of correlations between NOOS subscales, Short Form-36 subscales, and the Neck Disability Index were met using Spearman’s rank correlation coefficient. Ceiling/floor effects and measurement error were tested as well.

Results

The intraclass correlation coefficient results varied between 0.721 and 0.844. Cronbach’s alpha values of the subscale were found to be between 0.847 and 0.916 in the internal consistency analysis. The factor analysis showed that the questionnaire has five factors. Floor/ceiling effects were considered not to be present.

Conclusion

It was found that the Turkish version of the NOOS is valid and reliable.
