Reliability and validity of the visual analogue scale for disability in patients with chronic musculoskeletal pain

Cost-Effectiveness of "Tele-Square Step Exercise" for Falls Prevention in Fibromyalgia Patients: A Study Protocol

Background: Women with fibromyalgia (FM) have 2.5 falls per year compared to the 0.5 falls in people without FM. This fact poses a significant health expense. Square Stepping Exercise (SSE) is a balance training system that has been shown to be effective in preventing falls in the elderly. However, there are neither studies in people with FM nor studies that apply SSE through video-conferencing (Tele-SSE). The objectives of this project are 1) to investigate the applicability, safety, decrease in the number of falls, and incremental cost-effectiveness ratio of prevention of falls program through Tele-SSE in women with FM, and 2) to study the transfer of obtained results to the public and private socio-health economy of Extremadura. Methods/Design: A randomized controlled trial with experimental (Tele-SSE) and control (usual treatment) groups will be carried out. The application of Tele-SSE will be performed for 12 months (three times per week) and one additional follow-up month after the intervention. A focus group including agents to identify key points to transfer the findings to the public and private sectors in Extremadura. One-hundred and eighteen women with FM will be recruited and randomly distributed into the two groups: Experimental (Tele-SSE; n = 59) and control group (Usual care; n = 59). Primary outcome measures will be: 1) Applicability; 2) safety; 3) annual number of falls; and 4) incremental cost-effectiveness ratio. Secondary outcomes will be: 1) Balance; 2) fear of falling; 3) socio-demographic and clinical information; 4) body composition; 5) physical fitness; 6) physical activity and sedentary behavior; 7) quality of life-related to health, mental health, and positive health; 8) pain; 9) disability level; 10) cognitive aspects; and 11) depressive symptoms. Regarding the focus group, the acceptability of the Tele-SSE will be evaluated in social-sanitary agents and will include Tele-SSE in their services offer. A statistical analysis will be carried out by treatment intention and protocol. In addition, a cost-effectiveness analysis from the perspective of the health system will be performed. Discussion: This project aims to improve the efficiency and equity of physical therapy services based on tele-exercise in preventing falls in people with FM. Furthermore, orientations will be given in order to transfer the obtained findings into the social-sanitary system and market.

Non-specific chronic low back pain and physical activity: A comparison of postural control and hip muscle isometric strength: A cross-sectional study

Most research on sedentary lifestyle has focused on pain and disability, while neuromuscular outcomes (postural control and strength) have received less attention. The objective of the study was to determine whether low level of physical activity is negatively associated with measures of lower body muscular strength and postural control in individuals with and without non-specific chronic low back pain (NSCLBP).Twenty-four subjects with NSCLBP (28.8 ± 5.9 years) and 24 age, gender, and body mass index matched healthy controls participated in the study. Subjects were sub-classified into 4 subgroups based on their physical activity level: Non-active NSCLBP; Active NSCLBP; Non-active healthy control; and Active healthy control. Each subgroup consisted of 12 subjects. Peak force of hip muscles strength was assessed using a handheld dynamometer. Postural control was assessed using computerized posturography and the Y Balance Test.There was no significant group by physical activity interaction for strength and static and dynamic postural control, except for static control during left single leg stance with eyes closed (P = .029). However, there was a significant difference in strength and postural control by physical activity (P < .05). Postural control and peak force of hip muscles strength were significantly associated with physical activity (r ranged from 0.50 to 0.66, P < .001 and r ranged from 0.40 to 0.59, P < .05, respectively).Postural control and hip strength were independently related to physical activity behavior. A sedentary behavior may be an important risk factor for impaired postural control and hip muscles strength, and that physical fitness is vital to neuromuscular outcomes.

Association between extremely long working hours and musculoskeletal symptoms: A nationwide survey of medical residents in South Korea

OBJECTIVES

It has been reported that South Korea ranked as one of the longest-working nations among OECD countries. This study sought to examine the association between long working hours and musculoskeletal pain among Korean medical residents.

METHODS

We analyzed a cross-sectional survey of 1,077 medical residents in South Korea. Working hours per week were categorized as follows: <60, 60-79, 80-99, and ≥100. Musculoskeletal pains (ie, upper limb, lower limb, and low back pain) over the past 3 months were categorized into three groups: no pain, pain without interfering with work, and pain interfering with work. Multinomial logistic regression was used to examine the association between long working hours and musculoskeletal pains after adjusting for covariates.

RESULTS

We found that the average working hours of medical resident was 85.6 hours per week in South Korea. Compared to the medical residents working <60 hours, those working ≥100 hours per week were more likely to have upper limb pain (PR: 1.77, 95% CI: 1.37, 2.30) interfering with work or low back pain (PR: 2.15, 95% CI: 1.51, 3.06) interfering with work, whereas no statistically significant association was observed in the analysis of lower limb pain.

CONCLUSIONS

This study suggests that extremely long working hours are associated with upper limb and low back pain interfering with their work among Korean medical residents.

Psychological distress at hospital admission is related to symptoms severity and health status in malignant pleural effusion patients

OBJECTIVE

The incidence and associated healthcare costs of malignant pleural effusion (MPE) are expected to rise, but there is limited evidence about which factors affect patients' prognosis. So, the aim of this study was to determine whether psychological distress at hospital admission is associated with symptom severity and health status in patients with MPE.

METHODS

A longitudinal observational prospective cohort study was carried out in the Pulmonology Service of the Granada University Hospital Complex in Granada, Spain. Patients diagnosed with MPE were included and evaluated at hospital admission, at discharge and at one month after discharge. Outcome measures included symptom severity (i.e. dyspnoea, pain and cough) and health status (functionality and self-perceived health status).

RESULTS

Significant differences were found in symptoms and the health status, with worse results in the group with psychological distress at discharge. One month after discharge, MPE patients with psychological distress exhibited greater symptoms, including more cough and dyspnoea (p < .05). Moreover, these patients showed worse functionality (p < .05) and self-perceived health status (p < .05).

CONCLUSION

Psychological distress is an important factor to take into account in patients with MPE. The presence of psychological distress appears to increase the symptoms and is associated with worse health status after hospitalisation.

Motor Control Training Compared With Transcutaneous Electrical Nerve Stimulation in Patients With Disc Herniation With Associated Radiculopathy: A Randomized Controlled Trial

OBJECTIVE

The aim of the study was to compare the effectiveness of motor control training and transcutaneous electrical nerve stimulation in relieving pain, reducing functional disability, and improving transversus abdominis activation in patients with lumbar disc herniation with associated radiculopathy.

DESIGN

This is a randomized controlled trial.

METHODS

Forty patients diagnosed with lumbar disc herniation were randomly divided into two groups: motor control training group (n = 20) and transcutaneous electrical nerve stimulation group (n = 20).

INTERVENTIONS

The motor control training group and transcutaneous electrical nerve stimulation group attended 60 mini sessions twice a week for 8 wks, totaling to 16 sessions.

MAIN OUTCOME MEASURES

The main outcome measures are pain, functional disability, and transversus abdominis activation capacity.

RESULTS

Differences between both groups were observed after 8 wks, favoring the motor control training group. Motor control training was more effective than transcutaneous electrical nerve stimulation in relieving pain (mean difference = 3.3 points, 95% confidence interval = 2.12-4.48), reducing functional disability (mean difference = 8.4 points, 95% confidence interval = 5.44-11.36), improving the quality of pain (mean difference = 17 points, 95% confidence interval = 7.93-26.07), sensory quality of pain (mean difference = 10.3 points, 95% confidence interval = 5.55-15.05), and transversus abdominis activation (mean difference = 1.5 points, 95% confidence interval = 0.90-2.10).

CONCLUSIONS

The results suggest that motor control training is more effective than transcutaneous electrical nerve stimulation with respect to relieving pain, reducing functional disability, and improving transversus abdominis activation in patients with lumbar disc herniation.

The effectiveness of hydrodistension and physiotherapy following previously failed conservative management of frozen shoulder in a UK primary care centre

BACKGROUND

There is a lack of evidence on the clinical effectiveness of hydrodistension for frozen shoulder following failed conservative management.

METHODS

A total of 90 patients opted for hydrodistension following failed initial treatment which included physiotherapy and at least one corticosteroid injection. Shoulder pain and function were assessed at baseline, and 6, 12 and 24 weeks using the Shoulder Pain Disability Index (SPADI), The Upper Extremity Functional Index (UEFI) and a visual analogue scale (VAS) for pain. Active ranges of motion were assessed at baseline, post-24 hr and discharge.

RESULTS

We observed clinically important improvements in pain (VAS -5.5; 90% confidence interval [CI] -6.0 to -5.0; SPADI pain, -20; 90% CI-23 to -17) and function (UEFI 23; 90% CI 19 to 26; SPADI disability, -32; 90% CI -36 to -28) at 6 weeks. These improvements remained clearly substantial at 24 weeks. Active range of motion improved substantially post-24 hr (flexion 20, 90% CI 18 to 23; lateral rotation 14, 90% CI 12 to 16; abduction 22, 90% CI 19 to 25) and at discharge (flexion 37, 90% CI 33 to 41; lateral rotation 24, 90% CI 21 to 27; abduction 44, 90% CI 38 to 50).

DISCUSSION

This single-arm observational study suggests that hydrodistension is an effective treatment of frozen shoulder within a UK primary care setting when standard treatment has failed.

Combining transcutaneous electrical nerve stimulation with therapeutic exercise to reduce pain in an elderly population: a pilot study

PURPOSE

Chronic pain is a highly prevalent and debilitating condition, and there is a pressing need to find safe, effective and affordable treatments to tackle this public health issue. This pilot study aimed to assess whether therapeutic exercises supplemented by transcutaneous electrical nerve stimulation induces a greater hypoalgesic effect than therapeutic exercises supplemented by sham transcutaneous electrical nerve stimulation, in an elderly population suffering from chronic pain.

MATERIALS AND METHODS

Eighteen elderly participants suffering from chronic pain completed a therapeutic exercise program consisting of 45-min group sessions administered twice a week for 4 weeks. Half of the participants received real transcutaneous electrical nerve stimulation during the exercise sessions, while the others received sham transcutaneous electrical nerve stimulation. Participants completed pain questionnaires (McGill Pain Questionnaire, Brief Pain Inventory, Beck Depression Index) before and after the intervention, and recorded their pain levels on an 11-point numerical rating scale before and after each session (Clinical Trial.Gov ID: NCT02445677).

RESULTS AND CONCLUSION

Our results suggest that supplementing exercise sessions with transcutaneous electrical nerve stimulation does not improve the long-term outcomes of elderly patients suffering from chronic pain, but does induce short-term hypoalgesia during exercise sessions. Our study also offers valuable guidelines for the implementation of a future and adequately powered study looking at this research question.Implications for rehabilitationThe application of transcutaneous electrical nerve stimulation during exercises is well tolerated by elderly individuals suffering from chronic pain.Supplementing exercises with transcutaneous electrical nerve stimulation does not seem to improve general outcome in elderly suffering from chronic pain.Notwithstanding, the addition of transcutaneous electrical nerve stimulation tends to produce a marked hypoalgesic effect during the exercise sessions, an effect that could prompt indirect benefits for pain patients.

Is Dextrose Prolotherapy Superior To Corticosteroid Injection In Patients With Chronic Lateral Epicondylitis?: A Randomized Clinical Trial

Purpose

To compare the efficacy of dextrose prolotherapy versus steroid injection in the treatment of patients with chronic lateral epicondylitis.

Methods

Thirty subjects with chronic lateral epicondylitis were randomly assigned into two groups of hypertonic dextrose or methylprednisolone injection. Participants were assessed through Quick DASH and VAS scores, once before injection, and then after 1- and 3-months follow-up. Two patients were excluded due to not completing the follow-up timepoints.

Results

In both groups VAS scores revealed significant improvement during the first month follow-up [mean difference (MD) = 1.9±3.3, versus 1.5±1.9 for the prolotherapy and steroid groups, respectively]. This declining trajectory continued at the third month visit in the prolotherapy group and MD reached 4.4±2.9, while it did not change remarkably in the steroid group (MD=1.9±3.4). In fact, comparing VAS scores between the 1st- and 3rd-month time points did not reveal a significant improvement in the steroid group (p=0.6). Also, the Quick DASH index showed a similar pattern and improved remarkably in both groups during the first visit. However, only the efficacy in the prolotherapy group persisted after 3-month follow-up (MD = 9.5±21.6, p=0.044). One month after injections no preference between the two interventions was observed (p=0.74 for VAS and 0.14 for Quick DASH score). However, the 3rd-month follow-up revealed a meaningful superiority (p=0.03 for VAS and p=0.01 for Quick DASH score) favoring the prolotherapy method.

Conclusion

Both methods were proven to be effective in the short-term treatment of chronic lateral epicondylitis, but dextrose prolotherapy seems to be slightly more efficacious than steroid injection over a longer period.Clinical trial registration: Iranian Registry of Clinical Trials Database: IRCT20170311033000N3.

Gait Quality Assessment in Survivors from Severe Traumatic Brain Injury: An Instrumented Approach Based on Inertial Sensors

Despite existing evidence that gait disorders are a common consequence of severe traumatic brain injury (sTBI), the literature describing gait instability in sTBI survivors is scant. Thus, the present study aims at quantifying gait patterns in sTBI through wearable inertial sensors and investigating the association of sensor-based gait quality indices with the scores of commonly administered clinical scales. Twenty healthy adults (control group, CG) and 20 people who suffered from a sTBI were recruited. The Berg balance scale, community balance and mobility scale, and dynamic gait index (DGI) were administered to sTBI participants, who were further divided into two subgroups, severe and very severe, according to their score in the DGI. Participants performed the 10 m walk, the Figure-of-8 walk, and the Fukuda stepping tests, while wearing five inertial sensors. Significant differences were found among the three groups, discriminating not only between CG and sTBI, but also for walking ability levels. Several indices displayed a significant correlation with clinical scales scores, especially in the 10 m walking and Figure-of-8 walk tests. Results show that the use of wearable sensors allows the obtainment of quantitative information about a patient’s gait disorders and discrimination between different levels of walking abilities, supporting the rehabilitative staff in designing tailored therapeutic interventions.

Randomized clinical trial comparing buprenorphine/naloxone and methadone for the treatment of patients with failed back surgery syndrome and opioid addiction

Opioid analgesic consumption has led to an unprecedented epidemic of overdose death and opioid addiction in the US history. The treatment of chronic pain in patients with opioid addiction who receive prescriptions for opioid medications presents a clinical dilemma. Continuing opioid medication could result in hyperalgesia rendering opioids ineffective and results in iatrogenic therapeutic damage as evidenced by the worsening of addiction. Discontinuing opioid medications could result in severe pain and cravings that often leads the patient to the illicit market. This study compared methadone and buprenorphine/naloxone in patients with failed back surgery syndrome and opioid addiction. Nineteen participants were randomly assigned to methadone or buprenorphine/naloxone and were followed for 6 months. In an intent-to-treat analysis analgesia, craving, functioning, drug use, depression, and treatment retention were assessed monthly. It was planned to enroll 66 patients with failed back surgery syndrome and opioid addiction; however, enrollment was closed early due to suspected abuse of medications. Patients in both treatment conditions exhibited significantly improved 24-hour pain severity with up to 20% reduction of pain severity at the last follow-up (p < .05). However, patients receiving methadone reported significantly reduced current pain severity, whereas patients receiving buprenorphine/naloxone did not. Patients reported significantly improved functioning, fewer cravings, less opioid use, and depression (p < .05) across the treatment conditions. When given a choice between methadone and buprenorphine/naloxone, buprenorphine/naloxone is recommended due to its superior safety profile. Treatment with either needs to be monitored closely.

The influence of ergonomic breastfeeding training on some health parameters in infants and mothers: a randomized controlled trial

Background

Breastfeeding is considered as a protective factor against non-communicable diseases in infants and mothers. The first aim of this study was to assess the influence of ergonomic breastfeeding training on the infants’ growth. The second aim was to investigate the effectiveness of this training for improving musculoskeletal disorders in mothers.

Methods

In this randomized control trial, 104 participants who were referred to the health centers in Shiraz for breastfeeding care were randomly allocated into the intervention or comparison group using a size-four block sampling method. At birth, 2, 4, and 6 months later childbirth, Rapid Upper Limb Assessment was used to assess musculoskeletal disorders in participants, and the severity of their discomfort was measured with the Visual Analog Scale. During the 6 months of the study (March to September, 2017), the weight and height of the neonates were measured every 2 months.

Results

Significant differences were found between groups in the priority level for corrective action in mothers’ postures determined by Rapid Upper Limb Assessment at 2, 4 and 6 months after childbirth (p < 0.001). Based on the Visual Analog Scale results in mothers at 6 months after childbirth, fewer back pain was reported by the intervention group (p = 0.03). No significant difference were found in the infants^’ weights and heights in boys and girls at all growing stages between the two study groups (p > 0.05). However, the mean height for age of the girl infants at age of 6 months was higher among intervention groups compared to the controls (p = 0.01).

Conclusion

This study demonstrated that ergonomic breastfeeding training reduced the incidence of musculoskeletal disorders in mothers but seems not to have any significant and consistent impact on the infants’ growth.

The impact of exercise therapy and abdominal binding in the management of diastasis recti abdominis in the early post-partum period: a pilot randomized controlled trial

Purpose: To explore the feasibility of two physiotherapy interventions for the management of diastasis recti abdominis (DrA): abdominal binding and targeting trunk exercises.Methods: A pilot randomized controlled trial (RCT) design was used to compare the effectiveness of exercise therapy and/or abdominal binding to no intervention on thirty-two primiparous women who presented with DrA in the early post-partum period. Feasibility was determined based on study recruitment, compliance, and attrition rates as well as through computation of treatment effect sizes associated with each intervention compared to no intervention. Outcomes included inter-rectus distance measured using ultrasound, body image, pain, urogynecological symptoms, and function measured using questionnaires, and trunk flexion strength and endurance measured using clinical tests.Results: The recruitment rate was 3 participants/month. Intervention adherence rates were >50% and the attrition rate was 16%. After 6 months, positive effects (Cohen's d (d) = 0.2-0.5) on body image were observed in both the abdominal binding alone and combination therapy groups. A positive effect on trunk flexion strength (d = 0.7) was observed in the combination therapy group.Conclusion: The effect sizes suggest that physiotherapy interventions can positively impact body image and trunk flexion strength. While a clinical trial investigating these interventions is feasible, further preliminary investigation is recommended.

Older Adults With Hip Arthroplasty: An Individualized Transitional Care Program

BACKGROUND

Most older adults with hip fracture surgery experience functional decline (FD), causing devastating outcomes. However, few studies have examined the effects of nursing interventions to reduce FD for them.

PURPOSE

The aim of the study was to evaluate an individualized transitional care program (ITCP) to reduce FD for older adults with hip arthroplasty.

METHODS

The study was quasiexperimental, with a nonequivalent control group design. A total of 37 participants scheduled for hip arthroplasty were recruited-21 in the experimental and 16 in the control group.

FINDINGS

Two weeks following surgery (i.e., just prior to discharge), the ITCP group displayed less fear of falling than the usual care group. Moreover, the experimental group displayed objectively less FD with increased activities of daily living and Timed Up and Go scores, 6 weeks after hip arthroplasty.

CONCLUSIONS

This study provides evidence of the effectiveness of nurse-led rehabilitative practices to reduce FD in older adults with hip arthroplasty.

CLINICAL RELEVANCE

The ITCP promoted individual physical functioning for older adults with hip arthroplasty. This study results can aid healthy transitions of elderly patients with other various diseases.

Gait as predictor of physical function in axial spondyloarthritis: the prospective longitudinal FOLOMI (Function, Locomotion, Measurement, Inflammation) study protocol

Axial spondyloarthritis (axSpA) is a chronic inflammatory rheumatic disease affecting predominantly sacroiliac joints and axial skeleton. axSpA progression being irregular and hardly predictable, identifying functional decline is particularly important in patient with axSpA to allow delivery of timely and targeted interventions. Pain, reduced range of motion or altered posture can have adverse consequences on gait. Although gait has previously been used as a sensitive measure of physical outcomes in elderly and pathological populations, to the best of our knowledge, no study has used gait as a predictor of physical function in patients with axSpA. The objective of our study is hence to determine if gait parameters measured in patients with axSpA could predict the evaluation at 18 months of physical function as assessed by the Bath Ankylosing Spondylitis Functional Index (BASFI). This is a prospective and longitudinal study. Sixty patients with axSpA and 30 healthy age- and sex-matched controls will be included. Patients should be aged 18-65 years at time of their first evaluation, followed at Grenoble Alpes University Hospital for axSpA or ankylosing spondylitis, able to walk 180 m without technical help and with stable treatment for at least 12 months. Clinical characteristics, BASFI, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), clinical and laboratory measurements of gait will be assessed during four visits (at baseline and at months 6, 12, and 18). Similar assessments will be performed once for the healthy control group. A linear mixed model at 6, 12 and 18 months will be constructed to answer to the first objective, with the BASFI as dependent variable and gait parameters as explanatory variables. The data collection started in August 2018 and will be completed with the inclusion and follow-up of all the participants. We believe that the combination of clinical and laboratory measurements of gait in patients with axSpA could strengthen the capacity to monitor disease's evolution and to predict changes in patients' physical function. Results of the present study could ultimately allow delivering targeted, timely, personalized interventions and treatment in patients with axSpA.Trial registration: The study was approved by local ethic committee (CPP Ile De France 1, RCB: 2017-A03468-45, date of agreement: July 17th, last version: V4.0, 2018, March 5th, 2019) and is retrospectively registered in Clinical trials (NCT03761212).

Improving the response rate of patient-reported outcome measures in an Australian tertiary metropolitan hospital

Background: The benefits of collecting patient-reported outcome measures (PROMs) for clinical care are widely accepted; however, the collection and response rate remain a significant barrier.

Objective: The objective of this study was to assess predictors of successful PROM response rate in an orthopedic outpatient setting at a public tertiary hospital.

Method: A prospective cohort study was conducted at a metropolitan hospital assessing the response rate after a number of interventions in the collection of PROMs in the orthopedic outpatient setting. All patients were invited to complete a PROM relevant to their presenting condition. Eight cohorts were studied, all different in the process of collection, the timing of collection and the physical environment of collection. Analysis was completed in Stata v14.1 with collin commands used to assess collinearity. A multiple logistic regression model and a mixed effect logistic regression model were performed and compared. The significance level of p<0.05 was used.

Results: During the trial period 2,338 patients were seen. Response rates as high as 81% were seen, which was significantly improved compared with the earliest six cohorts (p<0.01). Being younger; being a new patient; having a longer wait time; having an English-speaking background and being a pre- or post-operative patient were all associated with an increased response rate of PROMs. Gender, the patient’s pathology and the type of PROM did not significantly affect the response rate.

Conclusions: The method employed to invite and inform patients of the PROM collection, and the environment in which it is undertaken, significantly alter the response rate in the completion of PROMs. Being younger, being a new patient, having a longer wait time, being English speaking, being a pre-op or post-op patient were all associated with an increase in response rate.

Reliability in Mandibular Movement Evaluation Using Photogrammetry in Patients With Temporomandibular Disorders

OBJECTIVE

The purpose of this study was to propose a quantitative evaluation for mandibular opening-closing movement asymmetries and to verify the intraexaminer and interexaminer reliability using photogrammetry in individuals with and without myogenic temporomandibular disorders.

METHODS

Forty-nine female participants between ages 18 and 40 were enrolled in this study. They were assigned to 2 different groups: a temporomandibular disorder group, (n = 25; 28.1 ± 3.6 years) and an asymptomatic group (n = 24; 25.6 ± 5.1 years). Data were collected through photogrammetry using Corel Draw X3 software (Corel Corp, Ottawa, Ontario, Canada) for angle measurements. Reliability analysis was done on the total sample, and the photographs were obtained by a singular examiner on 2 occasions (intraexaminer) 1 month apart and from measurement made by another examiner (interexaminer) on different days. The intraclass correlation coefficient (ICC) was applied with a significance level of 5%.

RESULTS

The photogrammetry had excellent intrarater and inter-rater reliability for the evaluation of opening and closing movements of the jaw (intrarater: opening ICC = 0.99; closing ICC = 0.98; inter-rater: opening ICC = 0.89 and closing ICC = 0.82). Photogrammetry also demonstrated excellent intra- and inter-rater reliability in the evaluation of head posture (intra-rater: head deviation ICC = 0.96; head position ICC = 0.75; inter-rater: head deviation ICC = 0.98; head position ICC = 0.98).

CONCLUSION

Under these experimental conditions, most angular values presented excellent intra- and interexaminer reliability.

High volume injection with and without corticosteroid in chronic midportion achilles tendinopathy

BACKGROUND

High volume injection (HVI) shows promising results in the treatment of chronic midportion Achilles tendinopathy (AT). HVI consists of a large volume of saline with a small amount of corticosteroid and local anesthetic.

OBJECTIVE

To determine the effect of corticosteroid in HVI in AT.

METHODS

A total of 28 men (18-59 years) with chronic (>3 months) AT were included in a double-blinded RCT and followed for 24 weeks. All performed eccentric training and randomized to either (a) HVI injection with corticosteroid or (b) HVI injection without corticosteroid. Outcomes included self-reported function (VISA-A score) and pain (VAS score) and ultrasound imaging (tendon thickness, Doppler flow).

RESULTS

VISA-A and VAS score improved in both groups at all time-points (P < 0.05). VISA-A improvement was significantly greater in HVI with corticosteroid (mean ± SEM; 6-weeks = 31 ± 3 points; 12-weeks = 32 ± 5 points) vs HVI without corticosteroid (6 weeks = 14 ± 3; 12-weeks = 17 ± 3) at 6 and 12 weeks (P < 0.05), but not at 24 weeks. Decrease in VAS scores was significantly greater in HVI with corticosteroid (6 weeks = 55 ± 3 mm; 12 weeks = 53 ± 5 mm) vs HVI without corticosteroid (6 weeks = 16 ± 3 mm; 12 weeks = 25 ± 5 mm) at 6 and 12 weeks (P < 0.05) but not at 24 weeks. Tendon thickness decreased significantly in both groups at all time-points (P < 0.05), but more in the HVI with corticosteroid vs HVI without corticosteroid at 6 and 12 weeks (P < 0.05) but not at 24 weeks.

CONCLUSION

High volume injection with or without corticosteroid in combination with eccentric training seems effective in AT. HVI with corticosteroid showed a better short-term improvement than HVI without corticosteroid indicating a short-term effect of corticosteroid in HVI treatment of AT.

Ultrasonic strain elastography for detecting abnormalities in the supraspinatus tendon: an intra- and inter-rater reliability study

OBJECTIVES

The reliability of ultrasonic strain elastography (SEL) used to detect abnormalities in the supraspinatus tendon is unclear. Thus, the aim of this study was to investigate the reliability of SEL in the supraspinatus tendon.

DESIGN

An intra-rater and inter-rater reliability study.

SETTING

A single-centre study conducted at the University of Southern Denmark.

PARTICIPANTS

Twenty participants with shoulder pain and MRI-verified supraspinatus tendinosis and 20 asymptomatic participants (no MRI).

PRIMARY AND SECONDARY OUTCOME MEASURES

Raw values (RAW) and ratios (deltoid muscle (DELT) and gel pad (GEL) as reference tissues) were calculated and mean values of measurements from three regions of the supraspinatus tendon were reported. Colour scale ratings and number of yellow/red lesions from the three areas were also included.

RESULTS

Intra-rater reliability showed intraclass correlation coefficients (ICCs) for RAW, DELT and GEL: 0.97 (minimal detectable change (MDC): 0.28 (6.36% of the mean)), 0.89 (MDC: 2.91 (20.37%)) and 0.73 (MDC: 1.61 (58.82%)), respectively. The ICCs for inter-rater reliability were 0.89 (MDC: 0.47 (10.53%)), 0.78 (MDC: 3.69 (25.51%)) and 0.70 (MDC: 1.75 (62.63%)), respectively.For colour scale ratings, intra-rater reliability (linear weighted kappa) ranged from 0.76 to 0.79, with the inter-rater reliability from 0.71 to 0.81. For the number of lesions, intra-rater reliability ranged from 0.40 to 0.82 and inter-rater reliability from 0.24 to 0.67.

CONCLUSIONS

Intra-rater and inter-rater reliability were excellent for raw values and for ratios with deltoid muscle as the reference tissue, and good for ratios with gel pad as the reference tissue. The reliability of colour scale ratings was substantial-to-almost perfect, and for the number of lesions fair-to-almost perfect.Although high reliability was found, validity and responsiveness of these elastographic methods needs further investigation.

ETHICS APPROVAL

The study protocol was approved by the Ethics Committee for the Region of South Denmark (S-20160115) and reported to the Danish Data Protection Agency (2014-41-3266).

Sarcopenia in patients with malignant pleural effusion: impact on symptoms, health status, and response to hospitalization

BACKGROUND

Malignant pleural effusion (MPE) refers to the presence of neoplastic cells in the pleural fluid and was previously associated with lung cancer, breast cancer, and lymphoma. Patients with MPE effusion have significant symptoms, diminishing their overall quality of life but little is known about the influence sarcopenia may have on their clinical presentation.

PURPOSE

To examine the prevalence of sarcopenia in patients with MPE and its relationship with symptoms, health status, and the response to hospitalization.

METHODS

Seventy-four patients with MPE underwent measurements of symptoms, health-related quality of life, and functional status upon admission, discharge, and 3 months after hospital discharge.

RESULTS

Patients with MPE and sarcopenia were symptomatic during hospitalization and at discharge. Additionally, health-related quality of life and functional status were worse in patients with MPE and sarcopenia. All measures of patients with MPE and sarcopenia were significantly poorer 3 months after hospital discharge.

CONCLUSIONS

Sarcopenia is a clinical characteristic with substantial negative effects in patients with MPE. Specific interventions may need to be provided, designed, and offered in the clinical setting.

Do Religious Coping and Attachment to God Affect Perceived Pain? Study of the Elderly with Chronic Back Pain in Iran

Religious Coping (RC) refers to the individual's ability to understand and cope with the stress in life. Attachment is a God relatively stable emotional bond that forms through continuous communication and requires interaction, pleasure and relaxation. Considering the increasing population of the elderly and the role of pain in their health status, the present study was conducted aimed to determine the relationship between RC and attachment to God with perceived pain in the elderly with chronic low back pain (CLBP) in Ilam in Iran. The present study is a descriptive cross-sectional one in the elderly group with chronic low back pain in 2018. A total of 300 elderly patients with chronic low back pain were enrolled using convenience sampling. The tools used included demographic characteristics form, religious coping questionnaire, attachment to God's questionnaire and perceived pain intensity questionnaire. The findings indicated that the mean (SD) of the total score of attachment to God variables was 65.71 (2.64), religious coping was 20.67 (2.59), chronic pain acceptance was 17.29 (6.66), and perceived pain was 5.81 (2.65). Also, there was a meaningful correlation between the intensity of the pain and the level of attachment to God and religious coping. Therefore, it is suggested that appropriate religious interventions for elderly patients with chronic pain should be undertaken to reduce their pain status in order to help improve their quality of life.

Effects of mirror therapy on muscle activity, muscle tone, pain, and function in patients with mutilating injuries: A randomized controlled trial

BACKGROUND

This study assessed the effectiveness of mirror therapy (MT) on muscle elasticity, pain, and function in patients with mutilating injuries.

METHODS

Thirty patients with impaired function due to mutilating injuries were assigned randomly to experimental or control group. The experimental group (n = 15) received MT (30 minutes a day, 3 days a week for 4 weeks) and conventional physical therapy after each MT session while the control group (n = 15) only received conventional physical therapy.

RESULTS

There were significant differences in pain and hand function within each group (pre-intervention vs post-intervention) and between groups (experimental vs control) (P < .05). However, there was no significant difference in muscle elasticity between groups (P > .05).

CONCLUSION

Although MT cannot result in significant changes in muscle elasticity in a clinical setting, it does have positive effects by reducing pain and improving hand function. Thus, MT can be effective for patients with impaired function due to mutilating injuries.

Bone marrow stimulation decreases retear rates after primary arthroscopic rotator cuff repair: a systematic review and meta-analysis

BACKGROUND

Despite the optimization of biomechanical and patient factors in the setting of rotator cuff repair (RCR), postoperative retear rates remain high in many series reported in the literature. Preclinical studies have suggested bone marrow stimulation (BMS) at the rotator cuff footprint may reduce the rate of retear after RCR. The objective of this meta-analysis was to analyze the clinical evidence investigating the effect of arthroscopic RCR, with and without BMS, on rotator cuff healing and functional outcomes.

METHODS

PubMed, MEDLINE, Embase, and the Cochrane Library were searched through December 2017. Two reviewers selected studies based on the inclusion criteria and assessed methodologic quality. Pooled analyses were performed for continuous and binomial variables where appropriate.

RESULTS

Four studies (365 patients), including 2 Level I randomized controlled trials and 2 Level III retrospective comparative cohort studies were included. There was no statistical difference in the Disabilities of the Arm, Shoulder and Hand score, University of California Los Angeles Shoulder Rating Scale score, or the Constant score between the BMS and conventional repair groups. The pooled retear rates were 18.4% (28 of 152) and 31.8% (56 of 176) for patients treated with and without BMS, respectively. The pooled analysis of rotator cuff retear rates from the 4 studies (328 patients) showed a statistically significant difference favoring BMS over conventional repair (odds ratio, 0.42; 95% confidence interval, 0.25-0.73; P = .002; I² = 0%).

CONCLUSION

BMS reduces the retear rate after RCR but shows no difference in functional outcomes compared with conventional repair. This study provides evidence for the use of BMS as a potential cost-effective biological approach toward improving rotator cuff healing.

Comparison of kinesio taping and occlusal splint in the management of myofascial pain in patients with sleep bruxism

OBJECTIVES

To evaluate the efficacy of Kinesio taping (KT) in patients with sleep bruxism (SB) and to determine whether KT may be an alternative for occlusal splint (OS) for the treatment of SB.

MATERIALS AND METHODS

Sixteen patients with SB were treated with KT (kinesio group) and 18 patients were treated with OS (splint group). Masseter and temporal muscle pressure pain thresholds (MPPT and TPPT), visual analogue scale (VAS) values and mouth opening measurements of patients were compared before treatment, and at the 1st and 5th weeks of treatment.

RESULTS

Both KT and OS treatments significantly reduced muscle pain, decreased VAS values, and increased mouth opening measurements. No statistically significant difference was found between the kinesio and splint groups in terms of MPPT, TPPT, VAS and mouth opening values before treatment and at the 1st and 5th weeks of treatment except for TPPT values at 1st week of treatment where the TPPT values of the kinesio group were significantly higher than the splint group (p< 0.05).

CONCLUSIONS

KT was identified as an easy-to-use treatment method for bruxism and was found to reduce muscle pain and increase mouth opening. KT is at least as effective as OS for the treatment of SB.

Translation, inter-rater reliability, agreement, and internal consistency of the Spanish version of the cumulated ambulation score in patients after hip fracture

Purpose: To translate the Cumulated Ambulation Score into Spanish, and to examine its inter-rater reliability, agreement and internal consistency.Materials and Methods: Two occupational therapists independently used the Spanish version of the Cumulated Ambulation Score (three activities scored from 0-2 points) to assess 60 consecutive patients with hip fracture within the first post-surgery week at a traumatology service of a public hospital. We used linear weighted kappa (κ) statistics to determine inter-rater reliability, percent agreement to assess measurement error, Cronbach's α coefficient to establish the internal consistency, and the McNemar-Bowker test to evaluate for systematic between-rater differences.Results: The κ was ≥ 0.83 for the three individual activities and the total score, the percent agreement was ≥ 0.87, and Cronbach's α was 0.89 with no observed systematic between-rater difference.Conclusions: This study provides evidence for almost perfect inter-rater reliability, excellent internal consistency, and high percent agreement of the Spanish version of the Cumulated Ambulation Score. Due to the strong psychometric properties, and its ease of use, we suggest it be used in Spanish speaking countries to assess early basic mobility status of patients with hip fracture until independence is reached.Implications for rehabilitationThe Spanish version of the Cumulated Ambulation Score is a reliable outcome measure to assess basic mobility of patients with hip fracture.We suggest the Spanish version of the Cumulated Ambulation Score be used in Spanish speaking settings to indicate small changes in basic mobility of patients with hip fracture until an independent level is reached.The Spanish version of the Cumulated Ambulation Score can be used with a high reliability by experienced and inexperienced occupational therapists, corresponding to the already established reliability when used by physicians and physiotherapists.

Hybrid Rehabilitation Therapies on Upper-Limb Function and Goal Attainment in Chronic Stroke

This study examined the treatment effects between unilateral hybrid therapy (UHT; unilateral robot-assisted therapy [RT] + modified constraint-induced movement therapy) and bilateral hybrid therapy (BHT; bilateral RT + bilateral arm training) compared with RT. Thirty patients with chronic stroke were randomized to UHT, BHT, or RT groups. Preliminary efficacy was assessed using the Fugl-Meyer Assessment (FMA), the Chedoke Arm and Hand Activity Inventory (CAHAI), and the goal attainment scaling (GAS). Possible adverse effects of abnormal muscle tone, pain, and fatigue were recorded. All groups showed large improvements in motor recovery and individual goals. Significant between-group differences were found on GAS favoring the hybrid groups but not on FMA and CAHAI. No adverse effects were reported. Hybrid therapies are safe and applicable interventions for chronic stroke and favorable for improving individual functional goals. Treatment effects on motor recovery and functional activity might be similar among the three groups.

Can Patients Forecast Their Postoperative Disability and Pain?

BACKGROUND

Forecasting is a construct in which experiences and beliefs inform a projection of future outcomes. Current efforts to predict postoperative patient-reported outcome measures such as risk-stratifying models, focus on studying patient, surgeon, or facility variables without considering the mindset of the patient. There is no evidence assessing the association of a patient's forecasted postoperative disability with realized postoperative disability. Patient-forecasted disability could potentially be used as a tool to predict postoperative disability.

QUESTIONS/PURPOSES

(1) Do patient-forecasted disability and pain correlate with patient-realized disability and pain after hand surgery? (2) What other factors are associated with patient ability to forecast disability and pain?

METHODS

We completed a prospective, longitudinal study to assess the association between forecasted and realized postoperative pain and disability as a predictive tool. One hundred eighteen patients of one hand/upper extremity surgeon were recruited from November 2016 to February 2018. Inclusion criteria for the study were patients undergoing hand or upper extremity surgery, older than 18 years of age, and English fluency and literacy. We enrolled 118 patients; 32 patients (27%) dropped out as a result of incomplete postoperative questionnaires. The total number of patients eligible was not tracked. Eighty-six patients completed the preoperative and postoperative questionnaires. Exclusion criteria included patients unable to give informed consent, children, patients with dementia, and nonEnglish speakers. Before surgery, patients completed a questionnaire that asked them to forecast their upper extremity disability (DASH [the shortened Disabilities of the Arm, Shoulder and Hand] [QuickDASH]) and pain VAS (pain from 0 to 10) for 2 weeks after their procedure. The questionnaire also queried the following psychologic factors as explanatory variables, in addition to other demographic and socioeconomic variables: the General Self Efficacy Scale, the Pain Catastrophizing Scale, and the Patient Health Questionnaire Depression Scale. At the 2-week followup appointment, patients completed the QuickDASH and pain VAS to assess their realized disability and pain scores. Bivariate analysis was used to test the association of forecasted and realized disability and pain reporting Pearson correlation coefficients. Unpaired t-tests were performed to test the association of demographic variables (for example, men vs women) and the association of forecasted and realized disability and pain levels. One-way analysis of variance was used for variables with multiple groups (for example, annual salary and ethnicity). All p values < 0.05 were considered statistically significant.

RESULTS

Forecasted postoperative disability was moderately correlated with realized postoperative disability (r = 0.59; p < 0.001). Forecasted pain was weakly correlated with realized postoperative pain (r = 0.28; p = 0.011). A total of 47% of patients (n = 40) were able to predict their disability score within the MCID of their realized disability score. Symptoms of depression also correlated with increased realized postoperative disability (r = 0.37; p < 0.001) and increased realized postoperative pain (r = 0.42; p < 0.001). Catastrophic thinking was correlated with increased realized postoperative pain (r = 0.31; p = 0.004). Patients with symptoms of depression realized greater pain postoperatively than what they forecasted preoperatively (r = -0.24; p = 0.028), but there was no association between symptoms of depression and patients' ability to forecast disability (r = 0.2; p = 0.058). Patient age was associated with a patient's ability to forecast disability (r = .27; p = 0.011). Catastrophic thinking, self-efficacy, and number of prior surgical procedures were not associated with a patient's ability to forecast their postoperative disability or pain.

CONCLUSIONS

Patients undergoing hand surgery can moderately forecast their postoperative disability. Surgeons can use forecasted disability to identify patients who may experience greater disability compared with benchmarks, for example, forecast and experience high QuickDASH scores after surgery, and inform preoperative discussions and interventions focused on expectation management, resilience, and mindset.

A comparison of 2 intravenous patient-controlled analgesia modes after spinal fusion surgery: Constant-rate background infusion versus variable-rate feedback infusion, a randomized controlled trial

BACKGROUND

Conventional intravenous patient-controlled analgesia (PCA), which usually involves constant-rate background infusion plus demand dosing, may cause adverse effects or insufficient analgesia. When variable-rate feedback infusion plus demand dosing mode is used, the infusion rate can be changed according to the patient's needs.

METHODS

In this prospective randomized double-blind study, 78 adults who were undergoing spinal fusion surgery were randomly allocated to either the constant-rate background infusion plus demand dosing group (group C) or the variable-rate feedback infusion plus demand dosing group (group V). The number of demands, volume delivered, numerical rating scale (NRS) score, adverse effects and the use of rescue analgesics were examined at 30 minutes after the operation in the post-anesthesia care unit, and at 6, 12, 24, and 48 hours.

RESULTS

The number of demands was significantly lower in group V than in group C at 12-24 hours (4.59 ± 4.31 vs 9.21 ± 6.79 times, P = .001) and over the total period. The volume delivered via PCA was significantly lower in group V than in group C at 12 to 24 hours (13.96 ± 13.45 vs 21.19 ± 8.66 mL, P = .006), 24 to 48 hours (13.39 ± 12.44 vs 33.6 ± 12.49 mL, P = .000), and over the total period. NRS scores, administration of rescue analgesics, and postoperative nausea and vomiting showed no between-group differences.

CONCLUSIONS

Variable-rate feedback infusion plus the demand dosing mode can control postoperative pain more efficiently, with lower dosages of analgesics, than constant-rate background infusion plus demand dosing in patients who undergo spinal fusion surgery.

A randomized controlled trial of Dilapan-S vs Foley balloon for preinduction cervical ripening (DILAFOL trial)

OBJECTIVE

The objective of the study was to test the hypothesis that Dilapan-S is not inferior to the Foley balloon for preinduction cervical ripening at term.

STUDY DESIGN

Pregnant women ≥37 weeks scheduled for induction with unfavorable cervix (≤3 cm dilated and ≤60% effaced) were randomly assigned to 12 hours of either Foley balloon inflated with 60 mL saline or Dilapan-S for cervical ripening. If the cervix remained unfavorable, then 1 more round of the assigned dilator was used. Management following ripening was left up to the clinical providers. The primary outcome was vaginal delivery. A satisfaction survey was also obtained after the preinduction period. Sample size was based on a noninferiority margin of 10%, 90% power, and an estimated frequency of vaginal delivery of 71% in Foley balloon and 76% in Dilapan-S.

RESULTS

From November 2016 through February 2018, 419 women were randomized (209 to Foley balloon; 210 to Dilapan-S). In the intent-to-treat analysis, vaginal delivery was more common in Dilapan-S vs Foley balloon (81.3% vs 76.1%), with an absolute difference with respect to the Foley balloon of 5.2% (95% confidence interval, -2.7% to 13.0%) indicating noninferiority for the prespecified margin. The difference was not large enough to show superiority. Noninferiority was confirmed in the per-protocol population (n = 204 in the Foley balloon, n = 188 in Dilapan-S), supporting the robustness of the results. Secondary outcomes were not different between groups, except for a longer time the device remained in place in Dilapan-S compared with the Foley balloon. Maternal and neonatal adverse events were not significantly different between groups. A priori interaction analyses showed no difference in the effect on vaginal delivery by cervical dilation at randomization, parity, or body mass index >30 kg/m². Patients with Dilapan-S were more satisfied than patients with the Foley balloon as far as sleep (P = .01), relaxing time (P = .001), and performance of desired daily activities (P = .001).

CONCLUSION

Dilapan-S is not inferior to the Foley balloon for preinduction cervical ripening at term. Advantages of Dilapan-S over Foley include Food and Drug Administration approval, safe profile, no protrusion from the introitus, no need to keep under tension, and better patient satisfaction.

Effects of therapeutic exercise on sea sand on pain, fatigue, and balance in patients with chronic ankle instability: a feasibility study

BACKGROUND

Chronic ankle instability (CAI) is a common disease following ankle sprain and appears balance and gait problems, pain, and fatigue. This study aimed to examine the effect of therapeutic exercise performed on sea sand on pain, fatigue, and balance ability in patients with CAI.

METHODS

This study was designed as a randomized controlled trial. Subjects with a Cumberland Ankle Instability Tool (CAIT) score of less than 27 were selected. 22 subjects were randomly assigned to the sea sand (SS) group (N.=11) or the self-management (SM) group (N.=11). The SS group performed the therapeutic exercise on sea sand and the SM group conducted the exercises on a firm surface at home 5 times over the course of a week. To measure static balance, center of pressure (COP) of one-leg standing on the force plate was assessed. Visual Analog Scale (VAS) was used to measure pain and fatigue.

RESULTS

The SS group showed statistically significant improvements in all static balance outcomes (COP-area, COP-average velocity, minor-axis, major-axis) after the intervention (P<0.05), while the SM group did not show a significant change in all static balance parameters (P>0.05). Also, the SS group showed statistically significant improvements in pain and fatigue (P<0.05). All outcomes except major axis showed statistically significant differences between SS group and SM group at change value (P<0.05).

CONCLUSIONS

Therapeutic exercise on sea sand effectively improved balance and decreased pain and fatigue. Thus, it can be considered a rehabilitation method for CAI patients.

Pain Behaviour Scale (PaBS): An Exploratory Study of Reliability and Construct Validity in a Chronic Low Back Pain Population

Objectives

To examine the interrater and intrarater reliability and construct validity of the Pain Behaviour Scale during standard physical performance tests in people with chronic low back pain and to confirm the test-retest reliability of the physical performance tests in this population. The Pain Behaviour Scale (PaBS) is an observational scale that was recently designed to uniquely measure both the presence and severity of observed pain behaviours.

Methods

Twenty-two participants with chronic low back pain were observed during performance of five physical performance tests by two raters. Pain behaviours were assessed using the Pain Behaviour Scale. The Visual Analogue Scale and Modified Oswestry Disability Index were used to measure pain and disability, respectively. Descriptive statistics were used to report demographic features of participants. Reliability was analyzed using ICCs. Rater agreement was analyzed using the weighted Cohen's kappa. Correlations between PaBS, self-reported measures, and physical performance tests were calculated using Pearson's product-moment correlations.

Results

The PaBS demonstrated excellent interrater (ICC₂,₁ = 1.0, 95% CI: 0.9 to 1.0) and intrarater (ICC_3,1= 0.9, 95% CI: 0.8 to 1.0) reliability. Component physical performance tests (i.e., time and distance) demonstrated good test-retest (0.6–1.0) reliability. Perfect agreement in the reporting of pain behaviours was found (95–100%). Correlations between pain behaviour severity and pain intensity (r = 0.6) and disability (r = 0.6) were moderate. Moderate correlations were found between pain behaviours and physical performance tests in sit to stand (r = 0.5), trunk flexion (r = 0.4), timed up and go (r = 0.4), and 50-foot walk (r = 0.4).

Conclusion

The Pain Behaviour Scale is a valid and reliable tool for measuring the presence and severity of pain behaviour, and the physical performance tests are reliable tests.

Contralateral segmental transcutaneous electrical nerve stimulation inhibits nociceptive flexion reflex in healthy participants

BACKGROUND

Transcutaneous electrical nerve stimulation (TENS) is a non-invasive treatment to relieve pain. Contralateral TENS (i.e. TENS administered to the contralateral side of a painful body part) is beneficial when TENS cannot be directly applied to pain site, such as in cases of trauma. Although TENS produces segmental analgesia in an ipsilateral limb, it has been unclear whether TENS produces higher analgesic effects in the contralateral segmental area. The aim of the present study was to investigate the analgesic effects of TENS in contralateral segmental or extra-segmental areas on physiological and subjective pain outcomes, using a nociceptive flexion reflex (NFR) method.

METHODS

We randomly allocated 60 healthy participants to three groups: contralateral segmental TENS (CS-TENS); contralateral extra-segmental TENS (CE-TENS); and contralateral placebo TENS (CP-TENS). CS-TENS was applied to right superficial sural nerve and CE-TENS was applied to the right superficial femoral nerve, each for 30 minutes. The magnitude of the NFR elicited by electrical stimulation of the left sural nerve was measured at baseline and at three subsequent 10-minute intervals. Subjective pain intensity was measured simultaneously with a visual analogue scale (VAS).

RESULTS

At 30 min, the NFR magnitude of CS-TENS group was significantly lower than that of the CP-TENS group (p = 0.021). There were no significant differences in VAS scores among the groups at any time point.

CONCLUSIONS

Our findings suggest that CS-TENS inhibited NFR. Although there was no significant between-group difference in subjective pain intensity, factors such as a placebo effect probably impacted it.

SIGNIFICANCE

Our findings provide support for the contralateral approach at stimulation sites when TENS cannot be directly administered to a pain site (e.g. due to disease or trauma).

Impact of local steroid application in a minimally invasive transforaminal lumbar interbody fusion: results of a prospective, randomized, single-blind trial

OBJECTIVELocal epidural steroid application may be associated with decreased pain and narcotic use in the immediate postoperative period following lumbar discectomy. However, local steroid delivery following lumbar fusion procedures has not been well characterized. This study aims to characterize the effect of local intraoperative depomedrol application on perioperative and postoperative outcomes following a single-level minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).METHODSA prospective, randomized, single-blinded study was performed. A priori power analysis determined that 86 patients were needed to detect a difference of 1 point in the visual analog scale (VAS) pain score between groups. Ninety-three patients were randomized into depomedrol (DEPO) and no depomedrol (NODEPO) cohorts. Prior to surgical closure, DEPO patients received 1 ml depomedrol (80 mg) applied directly to the surgical site by using a Gelfoam carrier. NODEPO patients received 1 ml saline on the same Gelfoam carrier. Perioperative outcomes including acute postoperative pain and narcotic use were assessed for the duration of inpatient stay. Patient-reported outcomes (PROs) questionnaires including VAS back and leg pain scores, and Oswestry Disability Index (ODI) were administered preoperatively and at 6-week, 12-week, and 6-month follow-up. Outcomes for DEPO and NODEPO cohorts were compared using linear regression controlled for sex.RESULTSOf the 93 patients, 45 (48.4%) were randomized to DEPO and 48 (51.6%) to NODEPO. A greater percentage of DEPO patients were female (53.3% vs 27.1%, p = 0.010). There were no other significant differences in patient baseline characteristics. Similarly, operating time, estimated blood loss, and length of inpatient stay did not differ between cohorts. Patients in the DEPO cohort consumed fewer hourly narcotics on postoperative day 0 (5.3 vs 6.3 oral morphine equivalents/hour, p = 0.034). However, no differences in acute postoperative pain or total narcotics consumption were observed between groups. Preoperative VAS leg scores were statistically different between cohorts (p = 0.027). However, preoperative ODI and VAS back scores did not differ between groups. Additionally, DEPO and NODEPO groups experienced similar improvements in PROs at all postoperative time points.CONCLUSIONSLocal depomedrol use did not lead to decreases in acute postoperative pain or narcotics consumption after MIS TLIF. Additionally, local depomedrol was not associated with postoperative improvements in PROs. The findings of this randomized trial suggest that surgical and clinical outcomes following MIS TLIF may not be impacted by intraoperative application of depomedrol.Clinical trial registration no.: NCT03308084 (clinicaltrials.gov).

Identification of Signs and Symptoms of Axillary Web Syndrome and Breast Seroma During a Course of Physical Therapy 7 Months After Lumpectomy: A Case Report

BACKGROUND AND PURPOSE

Axillary web syndrome (AWS) and seroma are common and function-limiting side effects following treatments for breast cancer. Studies of AWS and seroma are rare, and there are no guidelines for physical therapy in these cases.

CASE DESCRIPTION

After left breast lumpectomy due to invasive ductal carcinoma, a 65-year-old female patient underwent intraoperative radiation therapy and whole breast radiation. Seven months later, during treatment for breast swelling, AWS and breast seroma were identified by a physical therapist certified in lymphedema treatment. Treatment goals were to reduce breast swelling and pain and to improve shoulder movements. Interventions included manual lymph drainage, left arm stretching, and instruction about self-lymphatic-drainage and stretching exercise. Also, a compression bra was ordered, and continued daily activities and physical activity were recommended.

OUTCOMES

Improvement in shoulder movement, breast swelling, and pain.

DISCUSSION

Because evidence for treatment guidelines following treatments for breast cancer is lacking, close follow-up for treatment-related complications is recommended. Management should be chosen according to signs and symptoms. Realistic expectations can reduce patient frustration and improve coping strategies and compliance with self-treatment demands. Clinical studies to support these conclusions are required.

Comparing two dry needling interventions for plantar heel pain: a protocol for a randomized controlled trial

Background

Both manual therapy techniques and dry needling have shown to be effective treatment options for the treatment of plantar heel pain; however, in recent years, other techniques based on dry needling (DN), such as percutaneous needle electrolysis (PNE), have also emerged. Currently, PNE is being used in clinical practice to manage myofascial trigger points, despite the lack of studies comparing the effects of this technique over dry needling. Therefore, the aim of this randomized controlled study is to compare the effectiveness of DN versus PNE for improving the level of pain experienced by patients suffering from plantar heel pain provoked by myofascial trigger points.

Methods

A randomized controlled trial will be conducted with blinded participants and outcome assessors. A sample of 94 patients with a medical diagnosis of plantar heel pain will be recruited and divided into two treatment groups. Eligible participants will be randomly allocated to either (a) treatment group with DN and a self-stretching home program or (b) treatment group with PNE and a self-stretching home program. Each group will receive one treatment session per week over a period of 4 weeks. The primary outcome measure will be the pain subscale of the Foot Health Status Questionnaire. The secondary outcome measures will be a visual analogue scale for pain (average and highest level of pain experienced during the previous 48 h; level of pain immediately after the treatment session) and health-related quality of life (assessed using the EuroQoL-5 dimensions). Cost-effectiveness data will be extracted based on the EuroQoL-5 dimensions. Follow-up measurements will take place at baseline and at 4, 8, 12, 26, and 52 weeks.

Discussion

The justification for this trial is the need to improve current understanding regarding the effectiveness of treatments targeting the rehabilitation of plantar heel pain. This study will be the first randomized controlled trial to directly compare the effectiveness of DN and PNE combined with a specific stretching program for the treatment of plantar heel pain provoked by myofascial trigger points.

A comparative clinical and functional assessment of cortical button versus suture anchor in distal biceps brachii tendon repair

PURPOSE

The studies comparing the fixation methods being used for the ruptured distal biceps brachii tendon reinsertion show similar outcomes of cortical button and suture anchors usage, however, longer follow-up studies remain necessary. The goal of this study was to compare the clinical and functional three-year outcomes of the cortical button in contrast to the suture anchor fixation.

METHODS

A retrospective cohort study comprised of 28 males on average 3 years after surgical reinsertion of the distal biceps brachii tendon with the use of a cortical button (Group I, n = 11) or a suture anchor (Group II, n = 17). The outcomes assessed were range of elbow joint and forearm motion (ROM), arm circumferences, visual analogue scale (VAS), Mayo Elbow Performance Index (MEPI), Quick Disability of the Arm, Shoulder, and Hand (Quick DASH) and forearm flexor and supinator muscle torques measured under isometric and isokinetic conditions.

RESULTS

The comparison between the two studied groups revealed no statistically significant differences in ROM (p = 0.24-1.00), circumferences (p = 0.15-0.50), VAS (p = 0.71), MEPI (p = 0.23), Quick DASH (p = 0.61) or in the obtained muscle torque values (p = 0.07-1.00). However, differences in supination ROM between the surgical and non-surgical side were found in both groups (p = 0.01-0.02), and differences in pronation (p = 0.02) were found in Group II. The muscle torque values obtained in the surgical, dominant limb were lower than those in the nonsurgical, nondominant limb.

CONCLUSION

The comprehensive comparison of three-year outcomes of cortical button versus suture anchor fixations did not favour one fixation method over the other, and the results justify the clinical usage of both methods.

Spinal manipulation plus laser therapy versus laser therapy alone in the treatment of chronic non-specific low back pain: a randomized controlled study

BACKGROUND

Low back pain (LBP) is a common musculoskeletal disorder causing pain and disability in most of the countries. In recent years, new approaches such as Spinal manipulation and laser therapy have been considered as an alternative to conventional exercise and also found contradicting results in terms of its effectiveness.

AIM

A study to compare the combined effects of spinal manipulation, Laser and exercise versus Laser and exercise alone in chronic non-specific low back pain (cnLBP).

DESIGN

Randomized control study.

SETTING

Subjects with cnLBP were treated with spinal manipulation, Laser and exercise in outpatient department for four weeks.

POPULATION

Three hundred and thirty subjects who fulfilled the selection criteria were randomized (1:1:1 ratio) into SM-LT-CE (N.=110), LT-CE (N.=110) and control group (N.=110).

METHODS

The outcome measurements were Visual Analog Scale (VAS), Modified Modified Schober Test (MMST) Roland and Morris Disability Questionnaire (RMDQ), Physical Health Questionnaire-9 (PHQ-9) and Health Related Quality of Life-4 (HRQOL-4). Baseline and follow-up measurements were measured at 4 weeks, 6 and 12 months by a blinded investigator.

RESULTS

Three hundred and twenty-six subjects completed the intervention and 304 completed the 12-month follow-up. Demographic variables show homogeneity between the groups and ANOVA analyses showed significant improvement (P<0.001) in pain reduction (VAS), flexion range of motion (MMST), functional disability (RMDQ), depression status (PHQ-9), and quality of life (HRQOL-4) in SM-LT-CE group compared to the other two groups at one-year follow-up.

CONCLUSIONS

Spinal manipulation combined with laser therapy and conventional exercise is more effective than laser therapy and conventional exercise alone in chronic non-specific low back pain.

CLINICAL REHABILITATION IMPACT

Spinal manipulation is an adjuvant intervention and it can be applied in every day clinical practice.

Land- and pool-based intervention in female fibromyalgia patients: A randomized-controlled trial

OBJECTIVES

The aim of this study was to assess the effect of a standard physical rehabilitation intervention (SPRI) program, in pool-based (SPRI-P) and land-based (SPRI-L) environments, applied to female fibromyalgia (FM) patients with mild-to-moderate symptoms during a period of 20 weeks.

PATIENTS AND METHODS

Between September 2016 and September 2017, a total of 73 female FM patients (mean age 48.2±6.8 years; range, 30 to 59 years) who suffered from FM were included in this study on a voluntary basis. The SPRI program was applied to the patients for 20 weeks. The severity of FM was assessed using the Fibromyalgia Impact Questionnaire. The dependent variables including self- perceived pain, perceived fatigue, aerobic capacity, depressive symptoms, and the overall impact of FM were evaluated.

RESULTS

Self-perceived pain, perceived fatigue, overall impact of FM (p<0.05) and depressive symptoms (p<0.001) of the participants in the SPRI-P program decreased in the post-test values, compared to the pre-test values. Using the SPRI-L program, a significant improvement in the aerobic capacity (maximum consumption of relative oxygen and distance in meters), overall impact of FM (p<0.05), and depressive symptoms (p<0.01) was observed.

CONCLUSION

Our study results indicated that the SPRI-P program yielded improvements in patients with FM in self-perceived pain, perceived fatigue, depressive symptoms, and overall impact, as well as improving the aerobic capacity. In addition, in the SPRI-L program, the participants increased their capacities, self-perceived pain, and overall impact of FM.

A home-based tele-rehabilitation protocol for patients with hip fracture called @ctivehip

Home-based tele-rehabilitation programs are under development and may be a future option for some patients. The objectives of this non-randomized clinical trial are to design a home-based multidisciplinary tele-rehabilitation protocol for patients with hip fracture, and to compare this protocol versus the home-based usual outpatient rehabilitation protocol. Seventy patients treated for an acute hip fracture, aged 65 years or older, with a high pre-fracture functional level (Functional Independence Measure score >90), without severe cognitive impairment, absence of terminal disease, discharged to their own home or a relativés home postoperatively, allowed weight-bearing, and with signed informed consent, will be allocated into a tele-rehabilitation group (n = 35) or a control group (n = 35). The inclusion criterion for the intervention group will be to have a caregiver with the ability to access the Internet who is willing to perform exercises and activities with the patient at home. The intervention includes a program of physical exercise and occupational therapy (five weekly sessions during 12 weeks), and recommendations for patients and their caregivers, all delivered through a website. The patient's functional level (Functional Independence Measure), quality of life (Euro-Qol), physical performance (Timed Up and Go), caregiver burden (Zarit Interview), and other descriptive data will be assessed at hospital discharge, 4 weeks, and 12 weeks. This project will add to the knowledge concerning the feasibility of tele-rehabilitation as an option to promote recovery of the pre-fracture functional level for some patients with a hip fracture.

Translation, cross-cultural adaptation, and psychometric properties of the Hausa version of the Fear-Avoidance Beliefs Questionnaire in patients with low back pain

Background and aims

The Fear-Avoidance Beliefs Questionnaire (FABQ) is the most widely used self-reported measure of fear-avoidance beliefs about work and physical activity in low back pain (LBP). However, there is no Hausa version for use in patients with LBP. This study aimed to translate, cross-culturally adapt, and test the psychometric properties of the Hausa version of the FABQ in patients with LBP.

Methods

The Hausa form of FABQ was developed using a forward-backward translation procedure according to recommended guidelines. The pre-final version of the questionnaire was pre-tested on 10 patients with acute LBP and 10 patients with chronic LBP. Psychometric testing was performed in 70 patients with acute LBP and 130 patients with chronic LBP. Reliability was assessed using internal consistency (Cronbach α) and test-retest reliability through intraclass correlation coefficient (ICC). Construct validity was assessed by exploratory factor analysis and divergent validity (Spearman rank correlation coefficient). Responsiveness was also investigated on 40 patients with chronic LBP.

Results

The Hausa version of the FABQ was successfully translated and proved to be well-understood. The internal consistency was adequate for the questionnaire (0.773) and its physical activity (0.816) and work (0.606) subscales. Test-retest reliability was excellent with an ICC value of 0.928 for the questionnaire and values of 0.901 and 0.863 for the physical activity and work subscales, respectively. Exploratory factor analysis yielded a three-factor structure in both acute and chronic LBP samples explaining 66.4% and 58.6% of the total variance, respectively. The first factor represents fear-avoidance beliefs due to work, the second factor represents fear-avoidance beliefs due to physical activity whereas the third factor represents the fear that pain aggravates due to work. Divergent validity showed moderate to weak correlation between the questionnaire and pain intensity (r=0.502), disability (r=0.415), lumbopelvic motion (r=0.00). The physical activity and work subscales weakly correlated (r=0.280). The effect size and standardized response mean were moderate to small with the work subscale having the lowest effect size (0.34) and standardized response mean (0.34) values. The MDC of the questionnaire was 5.4 points. The questionnaire had no ceiling or floor effects.

Conclusions

The FABQ was successfully translated into Hausa and cross-culturally adapted with acceptable psychometric properties similar to those of existing versions. The results suggest that the Hausa FABQ can be used to evaluate fear-avoidance beliefs about LBP in Hausa-speaking population for both clinical and research purposes.

Development of a Modified Disability Questionnaire for Evaluating Disability Caused by Backache in India and Other Developing Countries

STUDY DESIGN

Prospective observational study.

PURPOSE

To evaluate the disability domains relevant to Indian patients with low backache and propose a modified disability questionnaire for such patients.

OVERVIEW OF LITERATURE

The Oswestry Disability Index (ODI) is a self-reported measurement tool that measures both pain and functional status and is used for evaluating disability caused by lower backache. Although ODI remains a good tool for disability assessment, from the Indian perspective questions related to weight lifting and sexual activity of ODI are questioned in some of the earlier studies. Activities of daily living in Indian patients vary substantially from those in other populations and include activities like bending forwards, sitting in floor and squatting which are not represented in the ODI.

METHODS

In this prospective observational study, a seven-step approach was used for the development of a questionnaire. Thirty patients were interviewed to identify the most challenging issue they faced while performing their daily activities (by free listing) and understand how important the questionnaire items were in terms of the standard ODI. Thus, a comprehensive disability questionnaire comprising 14 questions was developed and administered to 88 patients. Both qualitative (interviews) and quantitative methods (to establish the validity, reliability, and correlation with the Visual Analog Scale [VAS] and Rolland Morris disability questionnaire) were used to identify the 10 questions that best addressed the disability domains relevant to Indian patients.

RESULTS

According to free listing, four new questions pertaining to bending forward, sitting on the floor, walking on uneven surfaces, and work-related disabilities were included. In the second phase, wherein the questionnaire with 14 items was used, 56.8% patients did not answer the questions related to sexual activity, whereas 23.8% did not answer those related to walking on uneven surfaces. The modified questionnaire demonstrated good internal consistency (Cronbach's alpha=0.892) and correlation with the Rolland Morris questionnaire (Cronbach's alpha=0.850, p>0.05), as well as with the VAS score for disability (Cronbach's alpha=0.712, p>0.05) and pain (Cronbach's alpha=0.625, p>0.05).

CONCLUSIONS

A modified disability questionnaire that was designed by adding two questions related to bending forward and work status and removing questions related to sexual activity and weight lifting or traveling (depending on the occupation) can help evaluate disability caused by back pain in Indian population.

Effects of muscle energy technique on pain, range of motion and function in patients with post-surgical elbow stiffness: A randomized controlled trial

Background:

Elbow is a very functional joint. Elbow stiffness is a significant cause of disability hampering the function of the upper extremity as a whole. Muscle Energy Techniques (METs) are relatively pain-free techniques used in clinical practice for restricted range of motion (ROM).

Objective:

To study the effects of MET on pain, ROM and function given early in the rehabilitation in post-surgical elbow stiffness.

Methods:

An RCT was conducted on 30 patients post elbow fracture fixation. Group 1 was given MET immediately post removal of immobilization while Group 2 received MET 1 week later along with the rehabilitation protocol. Pain (Visual Analogue Scale), ROM (goniometry) and function (Disability of Arm, Shoulder and Hand questionnaire) were assessed pre and post 3 weeks.

Results:

Group 1 showed greater improvement than Group 2, mean flexion and extension change between groups being 11.7±2.8, 95%CI(5.9,17.4) and 8.5±2.0, 95%CI(4.4,12.7), respectively. VAS and DASH scores improved better in Group 1, mean change being 1.2±0.2, 95%CI(0.6,1.8) and 18.2±2.2, 95%CI(13.5,22.8) for VAS and DASH scores, respectively.

Conclusion:

MET can be used as an adjunct to the rehabilitation protocol to treat elbow stiffness and can be given safely in the early stages of post elbow fracture rehabilitation managed surgically with open reduction and rigid internal fixation.

Compensatory strategy between trunk-hip kinematics and reaction time following slip perturbation between subjects with and without chronic low back pain

Compensatory trunk and hip motions following slip perturbations may compromise the control of lumbopelvic movement. However, it is unclear how postural integration of the trunk and hips can be transferred to treadmill-induced slip perturbations in subjects with chronic low back pain (LBP). The purpose of this study was to investigate trunk reaction times and three-dimensional trunk-hip angle changes following a slip perturbation (duration: 0.12 sec, velocity: 1.37 m/sec, displacement: 8.22 cm) with a handheld task between subjects with and without chronic LBP. There were 23 subjects with LBP and 33 control subjects who participated in the study. The trunk reaction time was not significantly different between groups. However, the three-dimensional trunk-hip angle changes were significantly different following the perturbation. There were significant interactions between the body regions and three-dimensional angles between groups. There was a negative correlation between reaction time and trunk flexion in the LBP group. Overall, the LBP group demonstrated significantly reduced trunk flexion, which might be associated with reduced adaptability or a possible fear of avoidance strategy. Clinicians need to consider compensatory strategies to improve trunk flexibility following slip perturbations in subjects with chronic LBP. Mini abstract: Trunk reaction time and three-dimensional trunk-hip motions were compared between subjects with and without chronic low back pain (LBP). The control group demonstrated greater trunk flexion; however, the LBP group reduced trunk flexion to protect against further injuries following the novelty of the slip perturbation.

The effect of a short term conservative physiotherapy versus occlusive splinting on pain and range of motion in cases of myogenic temporomandibular joint dysfunction: a randomized controlled trial

[Purpose] This study compared the effects of a short-term conservative physiotherapy program versus those of occlusive splinting on pain and range of motion in cases of Temporomandibular Joint Dysfunction. [Participants and Methods] This study included 112 male and female participants with ages ranging from 15–27 years. Outcome measures were pain assessed by the visual analogue scale and Temporomandibular Joint Range of Motion measured with the Temporomandibular joint opening index. Patients were randomly assigned to one of two groups. Conservative physiotherapy was provided to one group 3 days weekly while the other group received standard occlusive splinting. Splinting was used daily for the total period of treatment. Any adjustments for splints were done by the treating dentist. Both groups were treated for a total period of 6 weeks. [Results] Between group statistical analysis revealed a significant reduction in pain intensity and Temporomandibular joint opening index in favor of the conservative physiotherapy group. [Conclusion] Over a treatment period of 6 consecutive weeks, conservative physiotherapy could be a better initial treatment than occlusive splint in relieving pain and improving range of motion in cases of myogenic temporomandibular dysfunction.
