Dysfunction of circulating endothelial progenitor cells in major depressive disorder

OBJECTIVES

Despite mounting evidence demonstrates circulating endothelial progenitor cells (cEPCs) quantitative changes in depression, no study has investigated cEPC functions in major depressive disorder (MDD). We investigated the role of cEPC adhesive and apoptotic functions in MDD.

METHODS

We recruited 68 patients with MDD and 56 healthy controls (HCs). The depression symptoms, anxiety, psychosomatic symptoms, subjective cognitive dysfunction, quality of life, and functional disability were evaluated using the Hamilton Depression Rating Scale and Montgomery-Åsberg Depression Rating Scale, Hamilton Anxiety Rating Scale, Depression and Somatic Symptoms Scale (DSSS), Perceived Deficits Questionnaire-Depression, 12-Item Short Form Health Survey (SF-12), and Sheehan Disability Scale (SDS), respectively. Working memory and executive function were assessed using a 2-back task and Wisconsin Card Sorting Test (WCST). Inflammatory marker (soluble interleukin-6 receptor, C-reactive protein, and tumor necrosis factor-α receptor-1), cEPC adhesive, and apoptotic levels were measured using in vitro assays.

RESULTS

The MDD patients showed significantly lower cEPC adhesive levels than the HCs, and this difference in adhesive function remained statistically significant even after adjusting for inflammatory marker levels. The cEPC adhesion levels were in inverse correlations with commission and omission errors in 2-back task, the percent perseverative response and percent perseverative errors in WCST, and the DSSS and SDS scores, but in positive correlations with SF-12 physical and mental component scores. cEPC apoptotic levels did not differ significantly between the groups.

CONCLUSION

The findings indicate that cEPC adhesive function is diminished in MDD and impacts various aspects of cognitive and psychosocial functions associated with the disorder.

Pre-morbid sleep disturbance and its association with stroke severity: results from the international INTERSTROKE study

BACKGROUND AND PURPOSE

Whilst sleep disturbances are associated with stroke, their association with stroke severity is less certain. In the INTERSTROKE study, the association of pre-morbid sleep disturbance with stroke severity and functional outcome following stroke was evaluated.

METHODS

INTERSTROKE is an international case-control study of first acute stroke. This analysis included cases who completed a standardized questionnaire concerning nine symptoms of sleep disturbance (sleep onset latency, duration, quality, nocturnal awakening, napping duration, whether a nap was planned, snoring, snorting and breathing cessation) in the month prior to stroke (n = 2361). Two indices were derived representing sleep disturbance (range 0-9) and obstructive sleep apnoea (range 0-3) symptoms. Logistic regression was used to estimate the magnitude of association between symptoms and stroke severity defined by the modified Rankin Score.

RESULTS

The mean age of participants was 62.9 years, and 42% were female. On multivariable analysis, there was a graded association between increasing number of sleep disturbance symptoms and initially severe stroke (2-3, odds ratio [OR] 1.44, 95% confidence interval [CI] 1.07-1.94; 4-5, OR 1.66, 95% CI 1.23-2.25; >5, OR 2.58, 95% CI 1.83-3.66). Having >5 sleep disturbance symptoms was associated with significantly increased odds of functional deterioration at 1 month (OR 1.54, 95% CI 1.01-2.34). A higher obstructive sleep apnoea score was also associated with significantly increased odds of initially severe stroke (2-3, OR 1.48; 95% CI 1.20-1.83) but not functional deterioration at 1 month (OR 1.19, 95% CI 0.93-1.52).

CONCLUSIONS

Sleep disturbance symptoms were common and associated with an increased odds of severe stroke and functional deterioration. Interventions to modify sleep disturbance may help prevent disabling stroke/improve functional outcomes and should be the subject of future research.

Presence of Self-Reported Sleep Alterations After Stroke and Their Relationship With Disability: A Longitudinal Study

BACKGROUND

Sleep disorders have a prevalence of 30% to 70% in post-stroke individuals. The presence of sleep disorders and poor sleep quality after stroke can affect important functions and lead to worse outcomes. However, most studies are restricted to the acute post-stroke stage only.

OBJECTIVE

To investigate the frequency of self-reported sleep alterations in a sample of chronic stroke individuals and to identify which self-reported sleep alterations were associated with disability.

METHODS

Prospective exploratory study. Self-reported sleep alterations were measured by the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and STOP-Bang Questionnaire. The dependent variable was measured 3 years after the first contact by the Modified Rankin Scale (mRS). Step-wise multiple linear regression analysis was employed to identify which sleep alterations were associated with disability.

RESULTS

Sixty-five individuals with stroke participated. About 67.7% of participants had poor sleep quality, 52.4% reported insomnia symptoms, 33.9% reported excessive daytime sleepiness, and 80.0% were classified as intermediate or high risk for obstructive sleep apnea. Only risk for obstructive sleep apnea was significantly associated with disability and explained 5% of the variance in the mRS scores.

CONCLUSION

Self-reported sleep alterations had a considerable frequency in a sample of chronic stroke individuals. The risk of obstructive sleep apnea was associated with disability in the chronic stage of stroke. Sleep alterations must be considered and evaluated in the rehabilitation process even after a long period since the stroke onset.

Performance-related Pain and Disability among Music Students Versus Professional Musicians: a Multicenter Study using a Validated Tool

OBJECTIVE

To evaluate prevalence of performance-related pain among musicians and compare pain characteristics, associated disability and approach to pain management, between music students and professional musicians.

METHODS

A multicenter cross-sectional study was performed in a multi-stage stratified cluster random sample of 585 musicians, stratified by music students (294, among which 234 were at pre-university level and 60 at university level) and professional musicians (291). The main outcome was performance-related pain, measured by Performance-related Pain among Musicians Questionnaire (PPAM). Secondary outcomes were: pain management approach, physical activity levels, fatigue, distress, and health-related quality of life.

RESULTS

The lifetime prevalence of performance-related pain was 55.0% (n = 322), being significantly higher among professionals (57.5% versus 42.5%, p < 0.001). Pain intensity scores were significantly higher in professional musicians (p < 0,05), but pain interference in performance was higher among music students, who also reported significantly higher levels of fatigue (p = 0.008) and distress (p < 0.001), and lower quality of life (p < 0.001). Regardless of the high levels of pain intensity and interference, fatigue, anxiety and depression, and low levels of quality of life, 33% musicians who developed pain had never looked for healthcare (this proportion is significantly higher for music students, 57%, p < 0.001).

CONCLUSIONS

We present the first multicenter study on performance-related pain among musicians with different backgrounds, using a validated tool, and distinguishing music students from professional musicians. Performance-related pain is a highly prevalent and disabling condition among musicians, however, its proper evaluation and management are still often underappreciated, contributing to significant impairments and reduced quality of life.

Clinical Outcomes of Arthroscopic Surgery in Patients with Gluteal Muscle Contracture: Single-Institution Results from a High-Volume Cohort

BACKGROUND The aim of this study was to assess clinical outcomes of arthroscopic surgery for gluteal muscle contracture (GMC) with at least 2 years of follow-up in a large sample. MATERIAL AND METHODS A total of 665 patients who underwent arthroscopic release procedure at our institution between March 2014 and December 2018 and met the inclusion criteria were included in this study. All the patients were operated on by the same surgeon and the surgeon released the contracture band from anterior to posterior starting from the anterior edge of the ITB, the contracture band of the gluteus maximus, and vastus medialis tensor. After exclusion, 544 patients (218 males and 326 females) were finally included. Clinical outcomes at 2 years of postoperative follow-up were evaluated by a combination of several methods, including a new criterion we proposed for postoperative assessment, which included the cross-leg test, difficulty in squatting with legs together, and abnormal gait, the visual analogue scale (VAS), the modified Harris hip score (mHHS), and the satisfaction of patients. RESULTS The average follow-up time was 48.2±14.9 months. Based on the new criteria, 513 (94.3%) patients were evaluated as good, 25 (4.6%) as fair, and 6 (1.1%) as poor. The mHHS increased from 72.1±6.0 (range, 56.0-81.3) to 97.3±2.2 (range, 92.3-100.0) (P<0.001). The VAS decreased from 3.3±1.1 (range, 0-5) to 0.062±0.13 (range, 0-1) (P<0.001). For subjective satisfaction, 526 (96.7%) patients were satisfied, 14 (2.6%) patients were neutral, and 4 (0.7%) patients were dissatisfied. CONCLUSIONS In a large sample, favorable and durable clinical outcomes were observed after the arthroscopic procedure. Clinical symptoms and mHHS showed significant improvement with a minimum 2-year follow-up.

The relationship between lower extremity muscle tightness and pain and disability in individuals with non-specific chronic low back pain

BACKGROUND

Low back pain is a common health issue, and such pains are often associated with muscle tightness. Understanding the link between lower back pain and tight lower extremity muscles is essential for effective pain management and enhanced quality of life.

OBJECTIVE

The objective of this study was to investigate the relationship between lower extremity muscle tightness and pain and disability in individuals with non-specific low back pain (NSLBP).

METHODS

A total of 52 individuals with NSLBP were enrolled in this cross-sectional study. Lower extremity muscle tightness was assessed using various clinical tests, including the Active Knee Extension Test, Active Straight Leg Raise, Ober Test, and Modified Thomas Test. Pain intensity and disability were evaluated using the Visual Analog Scale and the Oswestry Disability Index, respectively. Statistical analyses were conducted to assess the correlation between muscle tightness, pain, and disability.

RESULTS

The study found weak to moderate negative correlations between lower extremity muscle tightness and both pain intensity and disability in individuals with NSLBP (r: -0.287 to -0.526, p <  0.05). Dominant and non-dominant extremities exhibited differences in muscle flexibility, with the dominant extremity showing greater flexibility (p <  0.05).

CONCLUSIONS

In individuals with NSLBP, lower extremity muscle tightness is closely related to pain severity and disability. These findings suggest that lower extremity muscle tightness plays a significant role in the severity of low back pain and disabilities. Additionally, the observed flexibility difference between dominant and non-dominant extremities warrants further investigation for more personalized treatment approaches.

Reliability and Acceptability to Caregivers of Telehealth Administration of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) for Brazilian Youth with Down Syndrome

Purpose

To estimate test-retest reliability of the two versions of the PEDI-CAT administered via telehealth to caregivers of Brazilian young people with DS, to compare scores on the two versions, and to determine caregiver acceptance of telehealth administration of the assessment.

Method

A methodological study approved by the research ethics committee. Data collection was performed online, with a mean duration of 45.0 minutes for the content-balanced version of the PEDI-CAT and 17.5 minutes for the speedy version.

Results

In total, 28 caregivers of individuals with DS up to age 21 years participated (mean = 5.9 years; SD = 4.9 years). Intra-class correlation coefficients for the four domains of the PEDI-CAT content-balanced version and four domains of the PEDI-CAT speedy version ranged from 0.77 to 0.97. There was a statistical difference between the versions in the scores of the social-cognitive domain (p < 0.05). A mean of 105 items (SD = 21) was administered in the content-balanced version and a mean of 51 items (SD = 8) in the speedy version. All the caregivers found the method of administration of the PEDI-CAT acceptable.

Conclusions

This study demonstrated that either version of the Brazilian version of the PEDI-CAT can be used by telehealth in clinical practice to assess children, adolescents, and young adults with DS.

Factors associated with delayed diagnosis of leprosy in an endemic area in Northeastern Brazil: a cross-sectional study

This study aimed to investigate the factors related to the individual and the health system that contribute to delayed diagnosis of leprosy in an endemic area in the Northeastern Brazil. This is a cross-sectional study of 120 individuals with leprosy. Demographic and clinical data and information on the factors related to the individual and the health system that contribute to delayed diagnosis of leprosy were obtained. Delayed diagnosis in months was estimated for each participant by interviews. A multivariate Poisson's regression analysis was performed between the outcome and the independent variables. The median delay in the diagnosis of leprosy was 10.5 (4.0-24.0) months. Approximately 12.6% of participants had grade 2 disability (G2D) at the time of diagnosis. In the multivariate Poisson regression analysis, males, older age, low schooling level, residing in urban areas, multibacellar or tuberculoid leprosy, not seeking healthcare immediately after symptom onset, suspected leprosy, excessive referrals, and the need for three or more consultations to confirm the diagnosis were associated with longer diagnostic delay. This study found a significant delay in the diagnosis of leprosy in Arapiraca, Northeastern Brazil, which may explain the continuously high rate of G2D among new cases. Factors related to the individual and the health system were associated with longer diagnostic delay. Interventions to raise awareness of the disease among the general population and strengthen primary health care are urgently needed.

Measurement properties of the Dutch versions of QuickDASH and PRWHE in patients with complaints of hand, wrist, forearm and elbow

BACKGROUND

The shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Patient Rated Wrist/Hand Evaluation (PRWHE) are commonly used questionnaires to assess patient-reported hand function. Information about the measurement properties of the Dutch versions is scarce.

OBJECTIVE

To gain insight into the measurement properties of the Dutch language versions of the QuickDASH and the PRWHE in patients with (non)specific complaints of the hand, wrist, forearm and elbow.

METHODS

Internal consistency, construct validity, test-retest reliability, responsiveness, and floor and ceiling effects were assessed according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations.

RESULTS

Questionnaires were filled out by 132 patients. Internal consistency of QuickDASH (Cronbach's α= 0.92) and PRWHE (Cronbach's α= 0.97) was high. Predefined hypotheses for construct validity were not confirmed for 75% for both QuickDASH and PRWHE (accordance with 62% of predefined hypotheses for both questionnaires). Test-retest reliability of QuickDASH (ICC = 0.90) and PRWHE (ICC = 0.87) was good. Both QuickDASH (AUC = 0.84) and PRWHE (AUC = 0.80) showed good responsiveness. No floor or ceiling effects were present.

CONCLUSIONS

Measurement properties of the Dutch language versions of the QuickDASH and the PRWHE, applied to patients with (non)specific complaints of the hand, wrist, forearm and elbow, were very similar. Test-retest reliability and responsiveness were good for both QuickDASH and PRWHE. Construct validity could not be demonstrated sufficiently.

Analysis of Hand Function, Upper Limb Disability, and Its Relationship with Peripheral Vascular Alterations in Raynaud's Phenomenon

This study aimed to compare vascular involvement, hand functionality, and upper limb disability between Raynaud's phenomenon participants and controls. Also, we analyzed the relationships between vascular impairment, mobility, and strength with disability in this Raynaud population. We conducted a case-control study with fifty-seven participants. We registered sociodemographic and clinical data; vascular variables (temperature, cold test, blood flow, and oxygen saturation); functional variables (pinch strength, range of motion), and disability (Shortened Disabilities of the Arm, Shoulder and Hand Questionnaire) (Q-DASH). Raynaud participants present more disability in all Q-DASH subscales, lower hands' temperature pre and post cold test, decreased blood flow on radial artery, decreased ranges of motions at passive extension of index finger, and active flexion and extension of thumb than the healthy controls. The multivariate regression analysis showed that extension of the index finger, lateral pinch strength, and oxygen saturation were significantly associated with disability in RP, almost the 55% of the total variance on the upper limb, 27% at sports/arts, and 42% at work. Our findings suggest that RP has a disabling effect on the upper extremities and a practice of activities in people who suffer it. Also, disability in Raynaud seems to be more related with hand mobility and strength impairment than vascular injury.

Use of the Oswestry Disability Index in ankylosing spondylitis

OBJECTIVE

The Oswestry Disability Index is considered the gold standard in the evaluation of disability in patients with chronic mechanical back pain. The aim of this study was to assess the applicability of Oswestry Disability Index in patients with ankylosing spondylitis and its relationship with disease assessment parameters for ankylosing spondylitis.

METHODS

A total of 100 patients diagnosed with ankylosing spondylitis were included in the study group. The control group consisted of 50 individuals with nonspecific low back pain. The Oswestry Disability Index and Bath Ankylosing Spondylitis Disease Activity Index were applied to both groups. In addition, the Visual Analog Scale, the Ankylosing Spondylitis Disease Activity Score C-Reactive Protein, the Ankylosing Spondylitis Disease Activity Score-the Erythrocyte Sedimentation Rate, the Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index, and the Ankylosing Spondylitis Quality of Life scales were applied in the study group. the Erythrocyte Sedimentation Rate, C-Reactive Protein levels, and HLA-B27 analysis were noted as laboratory markers in ankylosing spondylitis patients.

RESULTS

The scores of Oswestry Disability Index had a significant correlation with scores of Bath Ankylosing Spondylitis Disease Activity Index in ankylosing spondylitis patients (r=0.543) and in the control group (r=0.401). There was a significant correlation between the scores of Oswestry Disability Index and the Bath Ankylosing Spondylitis Functional Index (r=0.544), Bath Ankylosing Spondylitis Metrology Index (r=0.317), the Ankylosing Spondylitis Quality of Life (r=0.723), the Ankylosing Spondylitis Disease Activity Score-the Erythrocyte Sedimentation Rate (r=0.501), the Ankylosing Spondylitis Disease Activity Score C-Reactive Protein (r=0.530), Visual Analog Scale-Rest (r=0.476), and Visual Analog Scale-Activity (r=0.441) values in patients with ankylosing spondylitis.

CONCLUSION

Evaluation of Oswestry Disability Index in conjunction with Bath Ankylosing Spondylitis Disease Activity Index may warn the physician to interpret high Bath Ankylosing Spondylitis Disease Activity Index scores in the context of mechanical pain. Therefore, the use of Oswestry Disability Index in patients with ankylosing spondylitis will be beneficial.

The Upper Extremity Functional Scale for Prosthesis Users (UEFS-P): subscales for one and two-handed tasks

PURPOSE

To develop a self-report measure of activity performance for upper limb prosthesis users that quantifies outcomes by level of amputation and prosthesis type.

MATERIALS AND METHODS

Telephone survey of 423 adults with major upper limb amputation (ULA) who used a prosthesis. Item generation, cognitive, and pilot testing were followed by field testing. Items were categorized as one- or two-handed. Factor and Rasch analyses evaluated unidimensionality, monotonicity, item fit, differential item functioning (DIF), and reliability. Test-retest reliability was evaluated with intraclass correlation coefficients (ICCs). Known group validity was assessed with ANOVAs.

RESULTS

Respondents with unilateral ULA utilized prosthesis for 24% of unilateral and 38% of bilateral tasks. Those with bilateral ULA utilized prostheses for 64% of unilateral and 46% of bilateral tasks. Factor analyses identified a One-handed Task factor (CFI = 0.963, TLI = 0.950, and RMSEA = 0.064) and a Two-Handed Task factor (CFI = 0.958, TLI = 0.953, and RMSEA = 0.053). Response categories were collapsed to address monotonicity. After DIF adjustment, person reliability was 0.49 and 0.82 for One-handed and Two-handed Task scales, respectively, and ICCs were 0.88 and 0.91. Both scales differed by amputation level (p < 0.001).

CONCLUSIONS

The Upper Extremity Functional Scale for Prosthesis Users (UEFS-P) measure of upper limb function of prosthesis users has promising psychometric properties.Implications for rehabilitationMeasurement of upper limb function in persons with amputation is challenging, given currently available measures which do not explicitly grade activity performance with a prosthesis.The Upper Extremity Functional Scale for Prosthesis Users (UEFS-P) builds upon the original Orthotics and Prosthetics User Survey (OPUS) UEFS Scale with modified instructions, a revised item set, response categories and scoring algorithm.The UEFS-P consists of two unidimensional scales, the One-handed Tasks scale and the Two-handed Tasks scale.The UEFS-P scales have clear advantages over existing self-report measures of upper limb function that ask about difficulty with performing functional activities without accounting for prosthesis use, and do not differentiate persons who use and do not use a prosthesis.

Reliability of telemedicine evaluation for EDSS functional systems in multiple sclerosis

Introduction: There was an increase in telemedicine during the COVID-19 pandemic to follow patients with multiple sclerosis (MS). However, there is scarce data if online evaluations can cover important information assessed during in-clinic appointments, especially the Expanded Disability Status Score (EDSS). This study aims to develop a remote evaluation tool for EDSS functional systems and compare the performance with face-to-face evaluations. Methods: This was a single-center study that included all MS patients followed up at outpatient clinics of Hospital São Lucas Pontifícia Universidade Católica do Rio Grande do Sul, between April and August 2022. Initially, patients were routinely in-clinic evaluated by one trained neurologist for EDSS. After, patients were evaluated remotely without any information about the in-clinic EDSS results. We used a standardized interview with an interactive video platform to evaluate EDSS functional systems by telemedicine. Results: Forty-nine participants completed the two steps. Intra-class coefficient was 0.97 (95% CI: 0.95-0.98), concordance for EDSS below 4.0 was 0.87 (95% CI: 0.77-0.93) and ≥4.0 was 0.97 (95% CI: 0.89-0.99). There was perfect agreement in the final EDSS in 71.4% of the online and in-clinic evaluations. In the multivariate analysis, the visual (beta = 0.453; p = 0.003) and pyramidal (beta = 0.403; p = 0.009) systems contributed significantly to the difference in the final EDSS. Conclusion: The telemedicine tool created in this study can detect changes in functional systems with reliable results compared to in-clinic EDSS assessment. Telemedicine evaluations may reduce the number of in-clinic visits and the disease burden for patients with MS.

Stroke severity to determine musculoskeletal symptoms in family caregivers

OBJECTIVE

the objective of this study is to examine the relationship between the musculoskeletal problems experienced by the family members who care for stroke patients, physical health and disability levels.

METHOD

the subjects included in the study were patients and family caregivers admitted to the Kanuni Sultan Suleyman Training and Research Hospital Physical Medicine and Rehabilitation outpatient clinic with a stroke diagnosis between May 30 th, 2019, and May 30 th, 2021. The caregivers were assessed using the Extended Nordic Musculoskeletal Questionnaire. Validated scales were employed to evaluate stroke patients' physical health and disability level.

RESULTS

a total of 104 stroke patients and 104 caregivers who met our inclusion criteria took part in this study. Low back complaints in the last month were associated with the patients' Functional Ambulation Score (FAS), Functional Independence Measure (FIM), Stroke Impact Scale (SIS) and Brunnstrom scores. Neck pain was the second musculoskeletal complaint, but was not statistically associated with patient-related factors. Upper limb problems were associated with FAS, FIM, SIS, Brunnstrom and the Modified Ashworth Scale scores.

CONCLUSION

according to our findings, the low back is the body area most affected by musculoskeletal complaints in family caregivers of stroke patients, closely related to the patients' functional capacity and disability levels.

CLINICAL TRIALS NUMBER

NCT04901637 (1) Stroke survivors highly depend on informal caregivers for daily living. (2) Family caregivers are at an increased risk of experiencing musculoskeletal problems. (3) The caregivers' musculoskeletal symptoms are related to the level of the patient disability. (4) Preventive medicine should become a part of nursing education for family caregivers.

The International Classification of Functioning, Disability and Health Core Set for deafblindness. Part I: a systematic review of outcome measures

INTRODUCTION

The International Classification of Functioning, Disability, and Health (ICF), developed by the World Health Organization, is a classification framework that focuses on the health and functioning of people with disabilities. As part of an ICF Core Set development, four studies need to be conducted, one of which is a systematic review. This study presents part 1 of the systematic review that aims to describe the outcome measures identified in the literature related to functioning in individuals with deafblindness.

EVIDENCE ACQUISITION

The research team screened articles from eight scientific databases, three journals, and Google Scholar (March 2011 to September 2022). Articles were included if they studied individuals with deafblindness aged 18 and older. Studies that examined genetics or laboratory experiments involving animals were excluded. Data were extracted into a logbook with key descriptors such as study location and design, age of study population, and instruments/outcome measures used, which were further categorized into one of the following types: 1) standardized; 2) patient-reported measures, standardized (PT-S); 3) patient-reported measures, not standardized (PT-not S); 4) health professional, reported measures, standardized (HP-S); 5) Technical measures; 6) other measures (parent-reported standardized and laboratory measures).

EVIDENCE SYNTHESIS

The review included 147 studies, of which most were conducted in Europe (47.6%) and North America (27.9%). Of the 314 identified outcome measures, 57 were Standardized, 59 were Patient Reported-Standardized (PT-S), 178 were patient reported non-standardized (PT-Not S) variables, 11 were health professional reported, standardized, five were technical, and four were classified as other measures.

CONCLUSIONS

Most instruments measured functioning in daily activities and the mental health of individuals with deafblindness. Three deafblind-specific instruments were identified in this study, highlighting the need for more deafblind-specific instruments to be developed and utilized in research.

Multiple sclerosis functional tests and their comparability with self-administered values: A pilot study

Introduction

Neurological impairment in multiple sclerosis is highly variable among patients and over time it is difficult to quantify. The Multiple Sclerosis Outcome Assessment Consortium established sensitive, cost-effective, clinically significant, and reproducible measures of different functional systems to measure outcomes in clinical trials. However, their use in clinical care routines is not widespread due to time and training constraints.

Objective

To evaluate the self-administration feasibility of the timed 25-foot walking, symbol-digit-modality, and 9-peg hole tests in healthy individuals.

Materials and methods

We performed a descriptive pilot study. Healthy individuals between 18 and 80 years of age were included. The Timed 25-Foot Walking Test (T25- FWT), the Symbol Digit Modality Test (SDMT), and the Nine-Hole Peg Test (9-HPT) (using the dominant and non-dominant hand) were administered by a trained physician, who also instructed the subjects about test self-administration. The correlation and agreement, between the guided and self-administered tests were assessed with Pearson and Spearman coefficients and the Bland-Altman method.

Results

Thirty-eight healthy volunteers were included. The median age was 36 (range: 23-55) years old, and 55.26% were female. The correlation coefficient between guided and selfadministered tests was 0.37 for the T25-FWT (p=0.01), 0.54 for the SDMT (p<0.001), and 0.64 and 0.65 for the 9-HPT, in the dominant and non-dominant hands, respectively (p<0,001). Both forms of administration were concordant for the T25-FWT (95%CI: -1,49 to 1,43), the 9-HPT with dominant hand (95%CI: -5,23 to 4,09), the 9-HPT with non-dominant hand (95%CI: -7,75 to 7,14) and the SDMT (95% CI: -20,94 to 24,10).

Conclusions

We provide a proof of concept related to the feasibility of the selfadministration of the T25-FWT, the 9-HPT, and the SDMT, as a tool to improve monitoring in routine clinical practice.

Designing an evidence-based working method for medical work disability prognosis evaluation-an intervention mapping approach

Purpose

Performing evidence-based work disability prognosis evaluation (WDPE) of clients on sick leave is a difficult task for physicians. The aim was to develop a working method to support physicians in performing evidence-based WDPE and to improve WDPE quality.

Materials and methods

Intervention Mapping (IM) supplemented with elements of the Behavior Change Wheel (BCW) guided project planning for developing the working method. This approach allowed combination with other frameworks and, e.g., behavior change theories. WDPE quality challenges were analyzed on various ecological levels, e.g., the individual (i.e., the physician), interpersonal (i.e., the client) and organizational level, culminating into a multilevel logic model of the problem. Determinants that contributed to this problem, e.g., lack of physicians' knowledge on performing evidence-based WDPE, were identified. Performance objectives were formulated that could contribute to a desired change in WDPE quality. From the performance objectives and determinants (e.g., knowledge), change objectives were derived. In order to achieve these change objectives, suitable intervention functions (e.g., education) and policy categories (e.g., service provision) were identified, allowing the formulation of intervention components. Behavior change techniques (e.g., feedback on outcomes of a behavior) were selected to serve the intervention functions to deliver the desired change. This led to the conceptualization of an intervention plan.

Results

The intervention "Prognosable" is presented. It consists of a stepwise working method (SWM) for evidence-based WDPE. The SWM offers an overview of important aspects (e.g., medical condition, clients' confidence in return-to-work) to consider in individual clients' WDPE. The SWM helps physicians to identify crucial functional limitations, find and appraise evidence-based information, weigh all relevant prognostic aspects and it supports physicians to conclude with an evidence-based WDPE, tailored to the individual client. The intervention "Prognosable" was designed, which also includes an educational program and a supportive software tool to enable implementation of the SWM.

Conclusion

IM combined with BCW elements guided the development of a SWM for evidence-based WDPE. The SWM will be delivered through an educational program for physicians supported by a digital tool. The SWM, educational program and digital tool are ready to be implemented and evaluated in practice as the intervention "Prognosable."

Factors affecting association between pain severity and physical activity among people with low back pain

The aim was to identify factors, which may affect the relationship between physical activity and pain severity among patients with low back pain (LBP). It was a cross-sectional survey-based study among 1332 consecutive patients with LBP. Linear regression models were employed. Patients were 47.6 years old and 64% were women. For the entire sample, pain severity and the intensity of physical activity were negatively associated. Higher physical activity was associated with younger age, higher educational level, normal weight and optimal perceived general health. Sex, smoking, marital status and occupation did not demonstrate significant interactions on the association. The severity of disability showed paradoxical effect on the relationship between pain and physical activity - severe disability was associated with increase in physical activity.

Upper-Limb Disability and the Severity of Lymphedema Reduce the Quality of Life of Patients with Breast Cancer-Related Lymphedema

Breast cancer-related lymphedema (BCRL) is characterized by arm swelling, pain, and discomfort, reducing the quality of life (QoL) of affected individuals. BRCL is caused via the blockage or disruption of the lymphatic vessels following cancer treatments, leading to an accumulation of fluid in the affected arm. While current BCRL rehabilitation treatments seek to reduce arm swelling, our study aimed to examine the impact of both the magnitude of lymphedema (ΔVolume) and arm disability on three dimensions of QoL: social, physical, and psychological. Using the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and the Upper Limb Lymphedema 27 questionnaire (ULL) in a group of 30 patients, we found that the magnitude of lymphedema (ΔVolume) was associated with the social dimension of QoL (r = 0.37, p = 0.041), but not with other dimensions. On the other hand, arm disability was associated with all evaluated dimensions of QoL (social, physical, and psychological: p < 0.001, p = 0.019, and p = 0.050 (borderline), respectively). These findings suggest that BCRL rehabilitation strategies should not only aim to reduce the magnitude of lymphedema but should also seek to improve or preserve arm functionality to enhance the QoL of BCRL patients.

Reliability and validity of the Spanish adaptation of the Functional Independence Measure + Functional Assessment Measure

BACKGROUND

The Functional Independence Measure + Functional Assessment Measure (FIM+FAM) Scale is one of the most widely used instruments to measure functional independence post-stroke, and features many cultural adaptations to various languages.

AIM

The aim of this study was to determine the psychometric properties of a Spanish cross-cultural adaptation of the FIM+FAM for use in the stroke population.

DESIGN

Observational study.

SETTING

Outpatient long-term service of a neurorehabilitation unit.

POPULATION

One hundred and twenty-two individuals with stroke.

METHODS

The functional independence of the participants was assessed with the adapted version of the FIM+FAM. Additionally, the functional, motor and cognitive condition of the participants was assessed with a battery of standardized clinical instruments. Finally, a group of 31 participants out of the total were evaluated a second time with the FIM+FAM by a different evaluator than the one who performed the first evaluation. Internal consistency, inter-rater reliability and convergent validity with other clinical instruments of the adapted version of the FIM+FAM were determined.

RESULTS

The internal consistency of the adapted version of the FIM+FAM was excellent, as evidenced by Cronbach's α values that exceeded 0.973. The inter-rater reliability was likewise excellent, with correlations above 0.990 in all domains and subscales. Additionally, the convergent validity of the scale adaptation with clinical instruments was variable, with values ranging from 0.264 to 0.983, but consistent with the construct assessed in the different instruments examined.

CONCLUSIONS

The internal consistency, inter-rater reliability and convergent validity of the Spanish-adapted version of the FIM+FAM Scale showed excellent reliability and validity of the adaptation, which supports its use to assess functional independence after stroke.

CLINICAL REHABILITATION IMPACT

Availability of a valid adaptation for the evaluation of functional independence after stroke in Spanish population.

Cross-cultural adaptation and validation of the Spanish version of the Oswestry disability index for Mexican population

PURPOSE

This study aimed to adapt a Spanish translation of the Oswestry Disability Index (ODI) into a cross-cultural version for the Mexican population. The objectives were to verify the validity and reliability of the adapted ODI and to compare pain perception between patients with and without obesity.

MATERIAL AND METHODS

We included 102 patients with low back pain from two neurosurgery departments in Mexico. The ODI questionnaire was translated and culturally adapted. Validity and construct were evaluated using exploratory factor analysis, and the external convergent validity was assessed by correlating ODI scores with pain intensity, age, and obesity. Test-retest reliability was calculated using the intraclass correlation coefficient, and confirmatory analysis was employed to validate the factorial structure.

RESULTS

Patients with obesity were older and had higher pain scores than patients without obesity. The exploratory analysis of the ODI in Mexican Spanish showed good reliability (Cronbach's alpha of 0.923) and validity (factorial loading range, 0.681 - 0.818). The confirmatory analysis showed almost null or very low discrepancy between the proposed model and the real data.

CONCLUSIONS

A Spanish translation of ODI was cross-culturally adapted for the Mexican population. The Mexican version of the ODI showed good reliability and validity in Mexican culture.

Women with patellofemoral pain show changes in trunk and lower limb sagittal movements during single-leg squat and step-down tasks

BACKGROUND

Changes in the trunk and lower limbs' sagittal movements may cause patellofemoral pain (PFP) because they influence the forces acting on this joint.

OBJECTIVES

To compare trunk and lower limb sagittal kinematics between women with and without PFP during functional tests and to verify whether sagittal trunk kinematics are correlated with those of the knees and ankles.

METHODS

A total of 30 women with PFP and 30 asymptomatic women performed single-leg squat (SLS) and step-down (SD) tests and were filmed by a camera in the sagittal plane. The trunk inclination angle, forward knee displacement, and ankle angle were calculated.

RESULTS

The PFP group exhibited less trunk flexion (SLS, p = .006; SD, p = .016) and greater forward knee displacement (SLS, p = .001; SD, p = .004) than the asymptomatic group; there was no significant difference in ankle angle (SLS, p = .074; SD, p = .278). Correlation analysis revealed that decreased trunk flexion was associated with increased forward knee displacement (SLS, r = -0.439, p = .000; SD, r = -0.365, p = .004) and ankle dorsiflexion (SLS, r = -0.339, p = .008; SD, r = -0.356, p = .005).

CONCLUSION

Women with PFP present kinematic alterations of the trunk and knee in the sagittal plane during unipodal activities. Furthermore, the trunk and lower limb sagittal movements were interdependent.

Disability evaluation in patients with Guillain-Barre syndrome and SARS-CoV-2 infection

Objective

Several cases of Guillain-Barre syndrome (GBS) associated with SARS-CoV-2 infection have been described. This study illustrated the demographic, clinical, and neurophysiological characteristics of patients with GBS and COVID-19, as well as associated factors with disability at discharge.

Materials and methods

A retrospective analytical observational study was conducted. It included patients diagnosed with GBS admitted in a national reference center in Peru between 2019 and 2021. Epidemiological, clinical, neurophysiological, and cerebrospinal fluid data were analyzed. A multivariate analysis, using the generalized linear model, was performed, considering the presence of disability at discharge as the dependent variable.

Results

Eight-one subjects diagnosed with GBS were included. The mean age was 46.8 years (SD: 15.2), with a predominance of males (61.73%). The most frequent clinical presentation was the classic sensory-motor form in 74 cases (91.36%) with AIDP (82.35%) as the most frequent neurophysiological pattern in the group with COVID-19, while AMAN pattern predominated (59.26%) in those without COVID-19 (p = <0.000). The disability prevalence ratio at discharge between subjects with COVID-19 and those without COVID-19 was 1.89 (CI 1.06-3.34), p = 0.030, adjusted for age, sex, and neurophysiological subtype.

Conclusion

The neurophysiologic subtype AIDP, and a higher disability were associated with the presence of COVID-19.

Prevalence of acute low back pain with risk of long-term disability and its correlates among medical students: A cross-sectional study

BACKGROUND

Low back pain (LBP) is responsible for the highest number of years lived with disability globally. There is a paucity of data regarding the same among medical students. So, this study was planned to estimate the prevalence of acute LBP having a high propensity to develop into chronic one as well as to determine associated correlates among medical students.

MATERIALS AND METHODS

This cross-sectional study was conducted among 300 medical students at a tertiary hospital using an Acute Low Back Pain Screening Questionnaire (ALBPSQ) to identify individuals with LBP and having a high risk of developing a long-term disability. ALBPSQ is a 21-question-based biopsychosocial screening instrument for identifying patients at risk of chronicity. ALBPSQ scores have been found to be significantly associated with pain and functional disability. Descriptive statistics, bivariate analysis, and multiple binary logistic regression have been performed through SPSS-22 software.

RESULTS

The prevalence of LBP having the propensity to develop into a long-term disability was found to be 14.3% (95% CI: 10.6-18.8). In bivariate analysis, higher age, no exercise, higher screen time, mental stress, studying in bed, abnormal posture, alcohol intake, tobacco use, positive family history, greater screen time per day, and more time spent in a sitting posture are significant with LBP. Stress ((adjusted odds ratio) AOR: 4.37, 95% CI: 1.79-10.68)), abnormally bent standing posture (AOR: 3.6, 95% CI: 1.3-10.6), and positive family of LBP (AOR: 3.6, 95% CI: 1.3-10.1) were found to be independent predictors of LBP among medical students.

CONCLUSION

Among medical students, every 15 out of 100 have a low back problem with chances of long-term disability. These students require early intervention to avoid long-term disability. Abnormal stooping posture, psychological stress, and positive family history of low pain might independently lead to LBP.

Fear-Avoidance Beliefs Are Associated with Pain Intensity and Shoulder Disability in Adults with Chronic Shoulder Pain: A Cross-Sectional Study

Shoulder pain is one of the most common musculoskeletal conditions, and for people over 40 years old, it represents the musculoskeletal pain with the greatest impact on quality of life. Psychological factors, such as fear-avoidance beliefs, are associated with musculoskeletal pain, and several studies suggest that they can influence various treatment outcomes. Our objective was to explore the cross-sectional association between fear-avoidance beliefs and shoulder pain intensity and disability in subjects with chronic shoulder pain. A cross-sectional study was conducted, and 208 participants with chronic unilateral subacromial shoulder pain were recruited. The shoulder pain and disability index assessed pain intensity and disability. The Spanish fear-avoidance components scale assessed the presence of fear-avoidance beliefs. The association between fear-avoidance beliefs and pain intensity and disability was analyzed by means of multiple linear regression models and proportional odds models, reporting odds ratios and 95% confidence intervals. Shoulder and pain disability scores were significantly associated with fear-avoidance beliefs (p < 0.0001, adjusted R-square 0.93, multiple linear regression). There was no evidence of an association between sex and age in this study. The regression coefficient for shoulder pain intensity and disability score was 0.67446. The proportional odds model showed an odds ratio of 1.39 (1.29-1.50) for shoulder pain intensity and disability total score. This study suggests that greater levels of fear-avoidance beliefs are associated with greater levels of shoulder pain and disability in adults with chronic shoulder pain.

Episodic Disability Questionnaire (EDQ) measurement properties among adults living with HIV in Canada, Ireland, United Kingdom, and United States

Background

The Episodic Disability Questionnaire (EDQ) is a generic 35-item patient-reported outcome measure of presence, severity and episodic nature of disability. We assessed the measurement properties of the Episodic Disability Questionnaire (EDQ) with adults living with HIV.

Methods

We conducted a measurement study with adults living with HIV in eight clinical settings in Canada, Ireland, United Kingdom, and United States. We electronically administered the EDQ followed by three reference measures (World Health Organization Disability Assessment Schedule; Patient Health Questionnaire; Social Support Scale) and a demographic questionnaire. We administered the EDQ only 1 week later. We assessed the internal consistency reliability (Cronbach's alpha; >0.7 acceptable), and test-retest reliability (Intra Class Correlation Coefficient; >0.7 acceptable). We estimated required change in EDQ domain scores to be 95% certain that a change was not due to measurement error (Minimum Detectable Change (MDC95%)). We evaluated construct validity by assessing 36 primary hypotheses of relationships between EDQ scores and scores on the reference measures (> 75% hypotheses confirmed indicated validity).

Results

359 participants completed the questionnaires at time point 1, of which 321 (89%) completed the EDQ approximately 1 week later. Cronbach's alpha for internal consistency ranged from 0.84 (social domain) to 0.91 (day domain) for the EDQ severity scale, and 0.72 (uncertainty domain) to 0.88 (day domain) for the EDQ presence scale, and 0.87 (physical, cognitive, mental-emotional domains) to 0.89 (uncertainty domain) for the EDQ episodic scale. ICCs for test-retest reliability ranged from 0.79 (physical domain) to 0.88 (day domain) for the EDQ severity scale and from 0.71 (uncertainty domain) to 0.85 (day domain) for the EDQ presence scale. Highest precision was demonstrated in the severity scale for each domain (MDC95% range: 19-25 out of 100), followed by the presence (MDC95% range: 37-54) and episodic scales (MDC95% range:44-76). Twenty-nine of 36 (81%) construct validity hypotheses were confirmed.

Conclusions

The EDQ possesses internal consistency reliability, construct validity, and test-retest reliability, with limited precision when administered electronically with adults living with HIV across in clinical settings in four countries. Given the measurement properties, the EDQ can be used for group level comparisons for research and program evaluation in adults living with HIV.

Factors affecting hand cosmesis and the aesthetic impact of surgery on congenital hand differences in Finland

We assessed the appearance and cosmetic impact of surgery in congenitally different hands in Finland. A questionnaire was sent to 1165 respondents (786 female) with a mean age of 33 years (range 3-84). Participants were shown nine image pairs and seven pairs of pre- and postoperative images twice in a random order and asked to choose the more cosmetically pleasing one. We found that the appearance and number of fingers had an important aesthetic role, with higher number and more normal appearing digits consistently scoring higher than its counterpart (range 59-99%). Postoperative appearances were perceived as better than preoperative ones in syndactyly (98%), thumb duplication (92%), cleft hand (93%) and radial dysplasia (99%). Toe transfer and pollicization had little impact on cosmesis. This study demonstrated that surgery could improve cosmesis in congenitally different hands and overall, most respondents prefer an appearance that is as close as possible to normality. Level of evidence: IV.

Development of a candidate item bank for measuring mobility of lower limb orthosis users

BACKGROUND

Orthoses are often prescribed to improve mobility of people with chronic health conditions that affect lower limb function. Patient-reported survey instruments can be used to measure aspects of mobility that cannot be easily assessed in clinical or research settings. A population-specific item bank could be designed to measure aspects of mobility that are most important to lower limb orthosis users and used to evaluate the effects of orthoses.

OBJECTIVE

To develop items for a new survey instrument to measure mobility of lower limb orthosis users.

DESIGN

Survey items were developed using a qualitative item review process.

SETTING

Focus groups were held by video conferencing. Cognitive interviews were conducted by telephone.

PARTICIPANTS

Focus group and cognitive interview participants were adults with at least 6 months of experience using a lower limb orthosis that extended from the foot to a level above the ankle.

METHODS

Research methods included focus groups with lower limb orthosis users, an item generation and reduction process that involved a stakeholder advisory panel, and cognitive interviews with target respondents.

RESULTS

A total of 1180 extant items were identified in a literature review. Focus group participants (n = 29) provided feedback that informed the suitability of a construct definition and conceptual model. An advisory panel contributed to the selection of 118 candidate items for measuring orthotic mobility. Feedback from cognitive interview participants (n = 30) informed removal or revision of problematic items, resulting in a candidate bank of 100 mobility items.

CONCLUSIONS

The rigorous qualitative methods applied here resulted in a large set of candidate items that spanned a range of situations relevant to moving with a lower limb orthosis. Next steps include administration of the candidate items to a large sample of lower limb orthosis users and calibration of the item bank.

Pain and Motor Function in Myotonic Dystrophy Type 1: A Cross-Sectional Study

Pain is an underestimated finding in myotonic dystrophy type 1 (DM1). We provide a characterization of pain in terms of functional implications through a multidimensional assessment in patients with DM1, focusing on gender differences. We assessed pain through the Brief Pain Inventory (BPI) and its indexes (the Severity Index (SI) and the Interference Index (II)), balance/gait (the Tinetti Performance-Oriented Mobility Assessment (POMA)), functional abilities (the Functional Independence Measure (FIM)), and fatigue (the Fatigue Severity Scale (FSS)). We divided our sample into a mild (<4) and a moderate-severe group (≥4) based on BPI indexes. A between-group analysis was performed. We recruited 23 males and 22 females with DM1. A statistically significant difference was found for the FSS and the BPI-SI ≥ 4, and for all outcomes in the BPI-II ≥ 4 (p ≤ 0.003). In the female group, all outcomes except for the FIM were statistically significantly worse (p ≤ 0.004). Dividing our sample into four groups based on gender and the BPI, a statistically significant difference was found for FSS between the two groups with BPI-II ≥ 4 (with worsen score in the female one) (p < 0.002). Pain in DM1 patients is highly reported and gender related, with increased fatigue and poor balance/gait in the female group.

Concurrent validity of machine learning-classified functional upper extremity use from accelerometry in chronic stroke

Objective: This study aims to investigate the validity of machine learning-derived amount of real-world functional upper extremity (UE) use in individuals with stroke. We hypothesized that machine learning classification of wrist-worn accelerometry will be as accurate as frame-by-frame video labeling (ground truth). A second objective was to validate the machine learning classification against measures of impairment, function, dexterity, and self-reported UE use. Design: Cross-sectional and convenience sampling. Setting: Outpatient rehabilitation. Participants: Individuals (>18 years) with neuroimaging-confirmed ischemic or hemorrhagic stroke >6-months prior (n = 31) with persistent impairment of the hemiparetic arm and upper extremity Fugl-Meyer (UEFM) score = 12-57. Methods: Participants wore an accelerometer on each arm and were video recorded while completing an "activity script" comprising activities and instrumental activities of daily living in a simulated apartment in outpatient rehabilitation. The video was annotated to determine the ground-truth amount of functional UE use. Main outcome measures: The amount of real-world UE use was estimated using a random forest classifier trained on the accelerometry data. UE motor function was measured with the Action Research Arm Test (ARAT), UEFM, and nine-hole peg test (9HPT). The amount of real-world UE use was measured using the Motor Activity Log (MAL). Results: The machine learning estimated use ratio was significantly correlated with the use ratio derived from video annotation, ARAT, UEFM, 9HPT, and to a lesser extent, MAL. Bland-Altman plots showed excellent agreement between use ratios calculated from video-annotated and machine-learning classification. Factor analysis showed that machine learning use ratios capture the same construct as ARAT, UEFM, 9HPT, and MAL and explain 83% of the variance in UE motor performance. Conclusion: Our machine learning approach provides a valid measure of functional UE use. The accuracy, validity, and small footprint of this machine learning approach makes it feasible for measurement of UE recovery in stroke rehabilitation trials.

Gait and Sit-To-Stand Motor Compensation Strategies in Children and Adolescents With Duchenne Muscular Dystrophy

Duchenne Muscular Dystrophy (DMD), the most common form of muscular dystrophies, is characterized by progressive and generalized muscle weakness. The weakness of the trunk and other muscle groups leads these patients to perform motor compensation strategies to maintain their lower limb functionality for gait quality and for tasks such as getting up from a sitting position. In this cross-sectional observational study, we described and quantified trunk, gait, and sit-to-stand motor compensation strategies in different stages of this disease. Thirty-one ambulatory 5-18-year-old children and adolescents with a diagnosis of DMD, underwent cognitive assessment with the Mental Mini-Examination (MMSE) and motor assessment with the Vignos scale, Segmental Assessment of Trunk Control (SATCo-BR), Timed Up and Go test (TUG Test), and 10-m walk test. We found strong correlations between trunk and gait compensations, and identified motor compensation strategies characteristic of certain DMD classifications. Also, these lower limb and trunk compensations related to disease staging (Vignos) such that compensations were fewer for patients at relatively better disease staging.

Evaluation of functionality and socioeconomic status of patients with chronic pain

OBJECTIVE

This study aimed to evaluate the influence of chronic pain on functionality and its consequences on work and patient income.

METHODS

A total of 103 patients from the Multidisciplinary Pain Center of the Clinics Hospital of Universidade Federal de Minas Gerais were interviewed between January 2020 and June 2021, applying questionnaires on mobile devices. Socioeconomic data, multidimensional characterization of pain, and instruments for assessing pain functionality and intensity were analyzed. Pain intensity was categorized as mild, moderate, or intense for comparative analysis. Ordinal logistic regression was used to identify risk factors and variables that jointly influence the outcome of pain intensity.

RESULTS

The patients had a median age of 55 years, were predominantly female, married or in a stable relationship, white race, and completed high school. The median family income was R$2,200. Most patients were retired due to disability and pain-related causes. Functionality analysis showed severe disability directly associated with pain intensity. The financial impacts observed were correlated with the pain intensity of the patients. Age was a risk factor for pain intensity, while sex, family income, and duration of pain served as protective factors.

CONCLUSION

Chronic pain was associated with severe disability, decreased productivity, and exit from the labor market, with a negative impact on financial condition. Age, sex, family income, and duration of pain were directly associated with pain intensity.

Cervical Radiculopathy Impact Scale: Translation, cross-cultural adaptation, reliability and validity of the Turkish version

Objectives

The aim of this study was to translate and cross-culturally adapt the English version of the Cervical Radiculopathy Impact Scale (CRIS) and to investigate the validity and reliability of the Turkish version of the CRIS.

Patients and methods

Between October 2021 and February 2022, a total of 105 patients (48 males, 57 females; mean age: 45.4±11.8 years; range, 36.5 to 55.5 years) who were diagnosed with cervical radiculopathy due to disc herniation were included. Disability and quality of life were evaluated with the Neck Disability Index (NDI), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Short Form-12 (SF-12). Pain severity was evaluated using the Numerical Rating Scale (NRS) in three subscales (neck pain, pain radiating to the arm, and numbness in the finger, hand, or arm). The internal consistency for CRIS was assessed using the Cronbach alpha and test-retest reliability by intraclass correlation coefficients (ICCs). Explanatory factor analyses were performed for construct validity. To examine the content validity, the correlations among the three subgroup scores of CRIS and the other scale scores were analyzed.

Results

The internal consistency of CRIS was found to be high (α=0.937). A high reliability was obtained for test-retest reliability for the three subscales of CRIS (Symptoms, Energy and postures, Actions and activities) (ICC: 0.950, 0.941, 0.962, respectively; p<0.001). All three subscale scores of CRIS were correlated with the NDI, QuickDASH, SF-12 (physical and mental) and NRS scores (r=0.358-0.713, p<0.001). Factor analysis showed that the scale had five factors.

Conclusion

The CRIS is a valid and reliable instrument for Turkish patients with cervical radiculopathy due to disc herniation.

Tracking the impact of multiple sclerosis on employment status: the development of a questionnaire

BACKGROUND

Multiple sclerosis (MS) has a negative effect on employment status.

OBJECTIVE

To present the preliminary results of a special questionnaire designed to collect employment information on patients with MS.

METHODS

The questionnaire on the impact of MS on employment status was completed by 63 patients. Fatigue, cognition, and depression were also evaluated, and 33 healthy participants were recruited as a control group.

RESULTS

Regarding the patients' employment status, we found rates of 31.7% of full-time employment, 28.6% of part-time employment, 7.9% of unemployment due to MS, 4.8% of housewives, 1.6% retirement due to age, 15.9% of retirement due to disability, 7.9% of medical leave due to MS, and 1.6% of medical leave for other reasons. The rate of unemployment among the patients was significantly higher compared with that of the control group. Out of 38 working patients, 31% had been absent from work for the previous 3 months due to MS, and 50% had to make changes in their work to remain employed. Out of the 19 unemployed patients, 78% said that walking difficulties were the cause of unemployment, while 52% thought cognitive impairment was the cause.

CONCLUSIONS

The questionnaire provides a record of the employment status of patients with MS and describes the impact on work from their point of view.

POWERbreathe® Inspiratory Muscle Training in Amyotrophic Lateral Sclerosis

Inspiratory muscle training may benefit respiratory function, cardiocirculatory parameters, quality of life and functionality in neuromuscular diseases. This pilot study aimed to demonstrate the POWERbreathe® inspiratory muscle training effects on maximum inspiratory pressure (PImax), heart rate (HR) and HR variability, as well as the quality of life impairment and functionality in patients with Amyotrophic Lateral Sclerosis (ALS). A pilot single-blinded, non-randomized controlled clinical trial was carried out. A total of 20T ALS patients were enrolled and divided into experimental (n = 10) and control (n = 10) groups. The experimental group received POWERbreathe® inspiratory muscle training in conjunction with usual care, and the control group received only usual care for 8 weeks. PImax (measured by POWERbreathe® KH1), HR and HR variability (evaluated by Polar H7), quality of life impairment [measured by the Amyotrophic Lateral Sclerosis Assessment Questionnaire—40 items (ALSAQ-40)] and functionality [assessed by the ALS Functional Rating Scale Revised (ALSFRS-R)] were collected at baseline and after 8 weeks of intervention. We detected statistically significant differences (p < 0.05) with an effect size ranging from medium to large (Cohen’s d = 0.72−1.37); relative to the control group, the experimental group had an increased PImax (mean difference = 10.80 cm H2O; 95% CI = 3.42−18.17) and ALSFRS-R score (mean difference = 5.30 points; 95% CI = −0.03−10.63) and reduced HR (mean difference = −8.80 beats-per-minute; 95% CI = −20.27−2.67) and R-R interval (mean difference = 78.30 ms; 95% CI = 2.89−153.70). POWERbreathe® inspiratory muscle training, in addition to usual care, may improve inspiratory strength and heart rate in patients with ALS. These results encourage larger and longer trials investigating potential clinically relevant benefits of inspiratory muscle training to these patients over the disease course.

Development of the Web-Based Spanish Version of the Barthel Index in Patients with Multiple Sclerosis

BACKGROUND

The aims of this study were to develop a web-based Spanish form of the Barthel index (BI), to evaluate its psychometric properties and stability over time (test-retest), and to determine minimal detectable change (MDC) in patients with multiple sclerosis (MS).

METHODS

Participants answered the BI on two forms (web-based and face-to-face interview), 7-10 days apart. The internal consistency was evaluated using Cronbach's alpha, and intraclass correlation (ICC) and kappa (κ) coefficients were used to investigate the agreement between both forms.

RESULTS

143 participants were included. The Spanish web-based form of the BI showed excellent agreement between both forms for each item (κ = 0.86 (0.79 to 0.92), and for total score (κ = 0.87 (0.81 to 0.93); ICC = 0.99 (0.98 to 0.99). The internal consistency was good-excellent (Cronbach's alpha = 0.89 (0.86-0.91)). The stability over time was adequate, the agreement of each item was κ = 0.63 (0.52-0.74)), and for total score (ICC = 0.97), determining a MDC₉₅ of 12.09 points.

CONCLUSIONS

The Spanish web-based form of the BI is a valid and reliable tool to assess functionality and can be applied in both formats in patients with MS. A total score difference of more than 12 points was found to indicate a deterioration or improvement in the patient's functionality.

Multiple Sclerosis Progressive Courses: A Clinical Cohort Long-Term Disability Progression Study

OBJECTIVES

Improving the understanding of multiple sclerosis (MS) mechanism and disability progression over time is essential to assess the value of healthcare interventions. Poor or no data on disability progression are available for progressive courses. This study aims to fill this gap.

METHODS

An observational cohort study of patients with primary MS (PPMS) and secondary progressive MS (SPMS) was conducted on 2 Italian MS centers disease registries over an observational time of 34 years. Annual transition probabilities among Expanded Disability Status Scale (EDSS) states were estimated using continuous Markov models. A sensitivity analysis was performed in relation to clinical characteristic associated to disability progression.

RESULTS

The study cohort included 758 patients (274 PPMS and 434 SPMS) with a median follow-up of 8.2 years. Annual transition probability matrices of SPMS and PPMS reported different annual probabilities to move within EDSS levels. Excluding EDSS associated to relapse events or patient with relapses, the annual probability of staying stable in an EDSS level increased in both disease courses even not significantly.

CONCLUSIONS

This study provides estimates of annual disability progression as EDSS changes for PPMS and SPMS. These estimates could be a useful tool for healthcare decision makers and clinicians to properly assess impact of clinical interventions.

A picture is worth a thousand words: A proposal to incorporate video into the evaluation of adults with intellectual or developmental disability living outside the home

Adults with intellectual or developmental disability (IDD) comprise 1-2% of the population worldwide. IDD is a significant risk factor for premature morbidity or mortality. This is likely due in part to preventable health conditions, which are modifiable with the intervention of direct care providers in areas including nutrition, promotion of an active lifestyle and effective identification of health or functional deterioration. Adults with IDD are also at increased risk for neglect or mistreatment, a finding that has been documented across multiple countries and in a variety of care settings. Contributing factors include resource availability, lack of person-centered care, management culture and care worker training. Practical and economical interventions may address the known disparities and challenges facing the large community of adults with IDD. To promote person-centered care, improve record-keeping/documentation, and aid in protecting the health and safety of this vulnerable population, we propose incorporation of a video into the evaluation of adults with IDD living outside the home.

Neurologic Outcomes of Survivors of COVID-19-Associated Acute Respiratory Distress Syndrome Requiring Intubation

OBJECTIVES

To describe 3-6-month neurologic outcomes of survivors of COVID-19-associated acute respiratory distress syndrome, invasively ventilated in the ICU.

DESIGN

A bicentric prospective study during the two first waves of the pandemic (March to May and September to December, 2020).

SETTING

Two academic hospital ICUs, Paris, France.

PATIENTS

Adult COVID-19-associated acute respiratory distress syndrome survivors, invasively ventilated in the ICU, were eligible for a neurologic consultation between 3 and 6 months post ICU discharge.

INTERVENTIONS

Follow-up by face-to-face neurologic consultation.

MEASURES AND MAIN RESULTS

The primary endpoint was favorable functional outcome defined by a modified Rankin scale score less than 2, indicating survival with no significant disability. Secondary endpoints included mild cognitive impairment (Montreal Cognitive Assessment score < 26), ICU-acquired weakness (Medical Research Council score < 48), anxiety and depression (Hospital Anxiety and Depression score > 7), and posttraumatic stress disorder (posttraumatic stress disorder checklist for Diagnostic and Statistical Manual of Mental Disorders 5 score > 30). Of 54 eligible survivors, four non-French-speaking patients were excluded, eight patients were lost-to-follow-up, and one died during follow-up. Forty-one patients were included. Time between ICU discharge and neurologic consultation was 3.8 months (3.6-5.9 mo). A favorable functional outcome was observed in 16 patients (39%) and mild cognitive impairment in 17 of 33 patients tested (52%). ICU-acquired weakness, depression or anxiety, and posttraumatic stress disorder were reported in six of 37 cases (16%), eight of 31 cases (26%), and two of 27 cases (7%), respectively. Twenty-nine patients (74%) required rehabilitation (motor, cognitive, or psychologic). ICU and hospital lengths of stay, tracheostomy, and corticosteroids were negatively associated with favorable outcome. By contrast, use of alpha-2 agonists during ICU stay was associated with favorable outcome.

CONCLUSIONS

COVID-19-associated acute respiratory distress syndrome requiring intubation led to slight-to-severe functional disability in about 60% of survivors 4 months after ICU discharge. Cognitive impairment, muscle weakness, and psychologic symptoms were frequent. A large multicenter study is warranted to allow identification of modifiable factors for improving long-term outcome.

Socioeconomic participation of persons with hemophilia: Results from the sixth hemophilia in the Netherlands study

Background and objectives

Treatment availability and comprehensive care have resulted in improved clinical outcomes for persons with hemophilia. Recent data on socioeconomic participation in the Netherlands are lacking. This study assessed participation in education, in the labor market, and social participation for persons with hemophilia compared with the general male population.

Methods

Dutch adults and children (5–75 years) of all hemophilia severities (n = 1009) participated in a questionnaire study that included sociodemographic, occupational, and educational variables. Clinical characteristics were extracted from electronic medical records. General population data were extracted from Statistics Netherlands. Social participation was assessed with the PROMIS Ability to Participate in Social Roles and Activities short form, with a minimal important difference set at 1.0.

Results

Data from 906 adults and children were analyzed. Participation in education of 20 to 24 year olds was 68% (general male population: 53%). Educational attainment was higher compared with Dutch males, especially for severe hemophilia. Absenteeism from school was more common than in the general population. The employment‐to‐population ratio and occupational disability were worse for severe hemophilia than in the general population (64.3% vs. 73.2% and 14.7% vs. 4.8%, respectively), but similar for nonsevere hemophilia. Unemployment was 5.4% (general male population: 3.4%). Absenteeism from work was less common (38% vs. 45.2%). Mean PROMIS score was similar to or higher than in the general population (54.2; SD 8.9 vs. 50; SD 10).

Conclusion

Socioeconomic participation of persons with nonsevere hemophilia was similar to the general male population. Some participation outcomes for persons with severe hemophilia were reduced.

Roland-Morris disability questionnaire is bidimensional and has 16 items when applied to community-dwelling older adults with low back pain

PURPOSE

To explore the evidence of the internal structure validity of the Roland-Morris Disability Questionnaire in older adults with low back pain.

METHODS

This was a cross-sectional study of psychometric testing involving 528 older adults with low back pain. Internal structure validity was explored by exploratory factor analysis and semi-confirmatory factor analysis. Reliability was verified using Kuder-Richardson Formula 20, Cronbach's alpha, and McDonald's omega. Replicability was observed by the generalized H index.

RESULTS

Roland-Morris Disability Questionnaire displayed two factors that assess "functional capacity" and "mobility". Eight items were excluded for presenting cross-loading (2 and 10), inadequate loading factors and communalities (18, 24, 13, and 12), or did not relate to the latent construct (15 and 22). Semi-confirmatory factor analysis indicated that the questionnaire had a good fitness model [X² = 153.698 (p = 0.00001); RMSEA = 0.037; RMSR = 0.06; WRMR = 0.04; NNFI = 0.987; GFI = 0.979; AGFI = 0.971]. Reliability was acceptable (KR-20 = 0.79; Cronbach's alpha = 0.86; McDonald's Omega = 0.85), but replicability was poor in both factors (G-H factor 1 = 0.816-0.655; G-H factor 2 = 0.889-0.775).

CONCLUSIONS

The most appropriate version of the Roland-Morris Disability Questionnaire to apply to older adults with low back pain has 16 items and assesses functional capacity and mobility. IMPLICATIONS FOR REHABILITATIONThe RMDQ-16 is the most appropriate version of the RMDQ to use in older adults with LBP;The RMDQ-16 is bidimensional and assesses "functional capacity" and "mobility";The poor replicability of the RMDQ-16 indicates that it will probably not be stable across studies, but it can be useful in a clinical setting.

Chest wall volumes, diaphragmatic mobility, and functional capacity in patients with mucopolysaccharidoses

PURPOSE

We investigated respiratory muscle strength, diaphragm mobility, lung function, functional capacity, quality of life, body composition, breathing pattern, and chest wall (V_T,CW) and compartmental volumes of Mucopolysaccharidosis (MPS) patients and compared these variables with matched healthy individuals.

METHODS

A cross-sectional study with data analyzed separately according to age group. A total of 68 individuals (34 MPS and 34 matched-healthy subjects) were included. Six-minute walking test assessed functional capacity and ultrasound assessed diaphragm mobility during quiet spontaneous breathing (QB). Optoelectronic plethysmography assessed V_T,CW and breathing pattern during QB in two different positions: seated and supine (45° trunk inclination).

RESULTS

Body composition, lung function, respiratory muscle strength, and functional capacity were reduced in MPS (all p < 0.01). Diaphragm mobility was only reduced in adolescents (p = 0.01) and correlated with body composition and breathing pattern. Upper chest wall compartmental volumes were significantly lower in MPS, while abdominal volume only differed significantly in adolescents. Percentage contribution (%) of upper ribcage compartments to tidal volume was reduced in MPS children, whereas %AB was significantly increased compared with healthy subjects.

CONCLUSION

Lung function, respiratory muscle strength, functional capacity, diaphragm mobility, and quality of life are reduced in MPS compared with matched healthy subjects. V_T,CW was mainly reduced due to pulmonary and abdominal ribcage impairment. Implications for RehabilitationReduction in respiratory muscle strength, functional capacity, diaphragm excursion and low lung volumes were found in individuals with Mucopolysaccharidoses (MPS).Chest wall volumes and the upper chest wall compartmental volumes during quiet spontaneous breathing are reduced in MPS.Assessment and monitoring of the respiratory system for individuals with MPS should be performed periodically through standardized assessments to enable identification of changes and early intervention by rehabilitation protocols.This study may provide the necessary basis for carrying out respiratoty rehabilitation protocols that can improving chest wall mechanics with breathing exercise in this group.

Evaluation of lung function and clinical features of interlaminar cervical epidural steroid injections: a randomized controlled trial

OBJECTIVE

Interlaminar cervical epidural steroid injections (ICESIs) are commonly used to treat axial neck pain and cervical radicular pain. However, local anesthetics can spread to and block the phrenic nerve and upper segments of the thoracic spinal cord where the sympathetic innervation of the lungs emerges. Therefore, changes in lung function may occur following ICESIs.

METHODS

The primary outcome measure was the pulmonary function test (PFT) result 30 minutes before and after ICESI with ropivacaine (0.1875% or 0.25%). The secondary outcome measure was the comparison of the pain scores and functional disability between the two concentrations of ropivacaine 4 weeks after the ICESIs.

RESULTS

Fifty patients were randomly assigned to either the R1 (0.1875% ropivacaine) or R2 (0.25% ropivacaine) group. No significant difference was observed between the pre-ICESI and 30-minute post-ICESI PFT results within each group, and no difference was observed between the two groups. After 4 weeks of treatment, both groups showed a significant decrease in pain scores and functional disability; however, no significant differences were observed between the two groups.

CONCLUSIONS

This study showed no significant change in lung function after ICESIs in either group and no local anesthetic concentration-based difference in the clinical efficacy of the ICESIs.

Endovascular Treatment and Thrombolysis for Acute Ischemic Stroke in Patients With Premorbid Disability or Dementia: A Scientific Statement From the American Heart Association/American Stroke Association

Patients with premorbid disability or dementia have generally been excluded from randomized controlled trials of reperfusion therapies such as thrombolysis and endovascular therapy for acute ischemic stroke. Consequently, stroke physicians face treatment dilemmas in caring for such patients. In this scientific statement, we review the literature on acute ischemic stroke in patients with premorbid disability or dementia and propose principles to guide clinicians, clinician-scientists, and policymakers on the use of acute stroke therapies in these populations. Recent clinical-epidemiological studies have demonstrated challenges in our concept and measurement of premorbid disability or dementia while highlighting the significant proportion of the general stroke population that falls under this umbrella, risking exclusion from therapies. Such studies have also helped clarify the adverse long-term clinical and health economic consequences with each increment of additional poststroke disability in these patients, underscoring the importance of finding strategies to mitigate such additional disability. Several observational studies, both case series and registry-based studies, have helped demonstrate the comparable safety of endovascular therapy in patients with premorbid disability or dementia and in those without, complementing similar data on thrombolysis. These data also suggest that such patients have a substantial potential to retain their prestroke level of disability when treated, despite their generally worse prognosis overall, although this remains to be validated in higher-quality registries and clinical trials. By pairing pragmatic and transparent decision-making in clinical practice with an active pursuit of high-quality research, we can work toward a more inclusive paradigm of patient-centered care for this often-neglected patient population.

Are Work Demand, Support and Control Associated with Work Ability and Disability during Back Pain Treatment? A Prospective Explorative Study

Background: Low back pain is a multifactorial disease with consequences for work ability and social participation. Improved integration of the work domain in health care management is needed. The aim of this study was to explore the relation between working conditions with outcome of low back pain treatment. Methods: Observational study of 41 patients attending physiotherapy for low back pain. Work demands, support and control were registered at baseline and work ability and disability also at baseline, with follow up after three and nine months. We used mixed-effects models to estimate the longitudinal associations between working conditions and outcome. Results: Higher work demands were related to reduced work ability (−1.1 points, 95% CI: −2.1 to −0.1) and slightly increased disability (5.6 points, 95% CI: 0.5 to 10.7). Lack of social support from colleagues was associated with reduced work ability (−2.7 points, 95% CI: −0.2 to 1.5) and disability (14.0 points, 95% CI: 4.9 to 23.1). Conclusions: This explorative study found associations between work demands and support, and work ability and disability outcome. Screening for psychosocial working conditions may influence the work ability and disability treatment outcome. The results need replication in larger samples and may indicate that patients seeking primary care management for low back pain should be screened for work demands, support and control.

Functioning profiles of individuals with Mucopolysaccharidosis according to the International Classification of Functioning

BACKGROUND

The classification of health problems of persons with Mucopolysaccharidosis (MPS) based on the International Classification of Functioning, Disability and Health (ICF) may contribute to better understanding the disease impacts. The ICF is a useful tool to describe disabilities and functioning, especially in diseases with multisystemic involvement.

AIM

To identify and classify the health needs of persons with non-neuronopathic MPS according to the ICF.

DESIGN

A cross-sectional study.

SETTING

Department of Physical Therapy (Federal University, Brazil).

POPULATION

Persons with non-neuronopathic MPS.

METHODS

Semi-structured interviews covering all components of the ICF were conducted to know the patients' perspectives of their health problems (patient-reported outcomes). The speeches were transcribed verbatim and analyzed by researchers to identifying meaningful concepts. Then, the concept units were linked to ICF components and the magnitude of the problem to ICF qualifiers. Data are shown by descriptive statistics and separated into two groups: children and adolescents, and adults.

RESULTS

A total of 60 different ICF categories were used to classify participants' functioning. A total of 28 and 51 categories was necessary to classify the health problems of children and adults, respectively. Additionally, 16 categories related to contextual factors were used, of which eight and 12 were identified as facilitators by children, adolescents, and adults, respectively. The main problems were related to supportive functioning of arms or legs (b7603), pain in the body part (b2801), respiratory functions (b440), and voice functions (b310). Limitations in the activity and participation component were related to walking (d450), fine hand use (d440), washing oneself (d510), and dressing (d540). Recreation and leisure (d920) was restricted to approximately half of the studied population.

CONCLUSIONS

People with MPS face impairments of body structures and functions, activity limitations and restrictions to participation. Environmental factors may be act as facilitators of these problems.

CLINICAL REHABILITATION IMPACT

The ICF is a useful tool to classify the health problems of people with non-neuropathic MPS. The planning of rehabilitation programs needs to covers all components of functioning to provide a biopsychosocial model of care. The ICF categories may direct health professionals to more effective targets.

Systematic Review of the Socioeconomic Consequences in Patients With Multiple Sclerosis With Different Levels of Disability and Cognitive Function

Multiple sclerosis (MS) is a challenging and disabling condition, predominantly affecting individuals in early adulthood. MS affects the physical, cognitive, and mental health of persons suffering from the disease as well as having a great impact on their financial status and quality of life. However, there is a lack of systematic approach toward assessing the socioeconomic consequences of MS. Our objective was to systematically review analytical observational studies investigating the socioeconomic consequences in persons with MS with different levels of physical disability and cognitive function. We conducted a systematic review on socioeconomic consequences of MS with a focus on employment-, income-, work ability-, and relationship-related outcomes in persons with MS with special focus on disability and cognition. Additionally, the educational characteristics were examined. From 4,957 studies identified, 214 were assessed for eligibility and a total of 19 studies were included in this qualitative assessment; 21 different outcomes were identified. All identified studies reported higher unemployment, higher early retirement, and higher risk of unemployment in relation to higher physical disability. Also, cognitive function was found to be a predictor of employment (unemployment). The studies pointed out significant correlations between greater disability and lower earnings and higher income from benefits. A study found the same correlation in relation to cognitive function. The studies reported higher work disability in relation to higher physical disability and lower cognitive function. In conclusion, this systematic review summarizes the pronounced differences in various socioeconomic outcomes between patients with MS with regards to their physical disability and cognitive function. In addition, we identified a lack of studies with longitudinal design in this field that can provide more robust estimates with covariate adjustments, such as disease modifying treatments.

The use of the Washington Group on Disability Statistics questionnaires to identify hearing disability: a systematic review

PURPOSE

To investigate the use of instruments from the Washington Group on Disability Statistics (WG) to obtain data on hearing disability (HD).

RESEARCH STRATEGIES

We conducted searches in the PubMed, Scopus, Science Direct, Web of Science, Lilacs databases and the grey literature. The software "The State of the Art through Systematic Review" and "Mendeley" were used to assist in the bibliographic reference organization, selection, and storage.

SELECTION CRITERIA

we followed the guidelines proposed by the "Preferred Reporting Items for Systematic Reviews and Meta-Analysis" and we selected studies that met the following inclusion criteria: written in English or Portuguese, within the period of 2001 to 2017 and have used the WG hearing disability question.

DATA ANALYSIS

The variables analyzed into the studies were: WG module, country and year of data collection, sample size and composition, objective of the study, publication journal, HD estimate of prevalence and accuracy measures.

RESULTS

Sixty-five studies are included in the review, conducted with data from 30 countries. The WG Short Set of question was the most often used. Hearing disability prevalence ranged from 0.2 to 2.3% and only three studies estimated the accuracy of the instrument to identify HD.

CONCLUSION

The hearing disability question of WG has been used worldwide and mainly in developing countries. The short variation in the estimated prevalence measurements within studies seems favorable to the WG's goal of generate estimates that allow international comparison. However, the shortage of validity studies indicates the need for further investigations with this purpose.

Association between clinical evaluation and self perception of deglutition with motor disability scale in patients with multiple sclerosis

PURPOSE

To investigate the association between the clinical evaluation and self-perception of deglutition with the motor disability scale in patients with Multiple Sclerosis.

METHODS

It is a cross-sectional, prospective study that was conducted with individuals with Multiple Sclerosis treated by the Neuroimmunology outpatient clinic of a hospital in southern Brazil. We reviewed the electronic medical records of patients to extract the score from the last Expanded Disability Status Scale. After the analysis of the inclusion criteria, and in clinical consultation, two protocols were applied: one of self-perception for the risk of dysphagia, through the Brazilian equivalence instrument of the Eating Assessment Tool; and the clinical evaluation of swallowing, with food, through the scale Gugging Swallowing Screen. The data were analyzed through tables, descriptive statistics and the tests: Fisher's Exact Association Test and Chi-square Test to assess the association between the results of the applied scales. We considered a maximum significance level of 5% (p <0.05).

RESULTS

It was possible to observe that there was a significant association between the scores of the Gugging Swallowing Screen scales with the Expanded Disability Status Scale of the patients. In addition, there was also a relation between the results of both protocols with the Expanded Disability Status Scale.

CONCLUSION

The patients with Multiple Sclerosis in this study presented oropharyngeal dysphagia, what was confirmed by the association between the clinical evaluation of swallowing and the results of the instrument of self-perception of swallowing and the motor disability scale.

Changes in the International Classification of Functioning, Disability, and Health Components "Activity/Participation" as Predicted Through Patient-Reported Outcomes Along With Comprehensive Back Pain Rehabilitation

OBJECTIVES

The World Health Organization (WHO) recommended the International Classification of Functioning, Disability and Health (ICF) but its use in clinical practice is sparse. This study investigated the limitations and restrictions in the most relevant brief ICF core set categories for chronic low back pain (cLBP) as automatically predicted from routinely measured outcomes using a novel, validated mapping algorithm.

MATERIALS AND METHODS

Of 2718 cLBP patients recruited, data from 1541 (64% females) were available from before and at the end of 6 months comprehensive outpatient rehabilitation. Assessments included the Roland Morris Disability Questionnaire (RMDQ) and Pain Disability Index (PDI) questionnaires, the percentage of patients with predicted limitations and restrictions in important activity and participation ICF categories, bodily functional measurements, pain intensity, and anxiety/depression (EQ-5D).

RESULTS

At baseline, both the RMDQ and the PDI measures were within the third of the lowest disability scores whilst 80% of the patients had limitations with "maintaining a body position" and 30% with "walking" ICF categories. Intervention-associated gains in the maximum isometric lumbar extension and flexion strength and the lumbar range of motion were significant overall, but improvements in patients' ICF limitations/restrictions varied. Anxiety/depression, lumbar range of motion, and extension strength all had a significant impact on the majority of the ICF categories, whereas flexion strength had none.

DISCUSSION

The rate of patients with predicted limitations/restrictions in activity/participation ICF core categories for cLBP partly mirrored disability levels and the impact of the body function scores on these limitations/restrictions in ICF categories was varied. Thus, assessing problems in the ICF activity/participation core categories is of relevance to clinical practice for both treatment goal setting and intervention planning. This may be achieved by computer-generated mapping without additional time burden.
