Hand therapist management of the lateral epicondylosis: a survey of expert opinion and practice patterns

Scar massage as an intervention for post-surgical scars: A practice survey of Australian hand therapists

Introduction

Scar massage is a commonly used treatment in hand therapy. The current empirical evidence that supports it is disparate and of variable quality, with no established effective dosage and method proposed. This study aimed to identify the current practice among Australian hand therapists using massage as an intervention for scarring following surgery to the hand and upper limb.

Methods

A purposely designed self-report online survey was emailed to current members of the Australian Hand Therapy Association (n = 958). Data collected included demographics, intervention techniques, conditions treated and protocols, scar assessment and knowledge and training about scar massage as a clinical intervention.

Results

A total of 116 completed questionnaires were received (a response rate of 12.1%). All respondents used scar massage as part of their clinical practice with 98% to improve soft tissue glide (n = 114), 92% for hypersensitivity (n = 107), and 84% to increase hand function (n = 97). Only 18% (n = 21) of respondents used standardised outcome measures, and most therapists had learned scar massage from a colleague (81%).

Conclusions

Commonalities in how respondents implemented scar massage were found. Participants reported relying primarily on clinical experience to inform their practice. Whilst scar massage was widely used, few respondents had received formal skills training or completed outcome measures regularly to formally evaluate its clinical efficacy or impact. Replication of this study with a larger international sample of participants is warranted to determine if these findings reflect general practice.

Lateral Elbow Pain and Muscle Function Impairments

Although often described as a self-limiting condition and likely to resolve on its own, high recurrence rates and extended sick leave frame a need for effective non-surgical treatment for people with lateral elbow tendinopathy. The interrelationship of histological and structural changes to the tendon, the associated impairments in motor control, and potential changes in pain processing may all drive symptoms. This clinical practice guideline covers the epidemiology, functional anatomy and pathophysiology, risk factors, clinical course, prognosis, differential diagnosis, tests and measures, and interventions for managing lateral elbow tendinopathy in the physical therapy clinic.

Greek physiotherapists' contemporary knowledge and practice for lateral elbow tendinopathy: An online survey

OBJECTIVES

To investigate physiotherapists' current knowledge and practice in the management of patients with lateral elbow tendinopathy, to explore associations between the participants' education and management preferences and to identify potential evidence-to-practice gaps by making comparisons with recent research recommendations.

DESIGN

An on-line cross-sectional survey.

SUBJECTS

Registered physiotherapists working in Greece with previous experience in the management of lateral elbow tendinopathy.

RESULTS

Three hundred and seventy eight responses met the inclusion criteria. Most responders (70.4%-91.5%) use pain provocation tests for the diagnosis of the condition, while a limited proportion uses patient rated outcome measures (6.9%-13%). Supervised exercise is the mainstay of rehabilitation (92.6%), followed by adjunctive research recommended treatment techniques such as manual therapy (72%) and advice (59.5%). Up to 83.6% of participants use adjunctive treatment techniques that are not recommended or without research recommendation (such as electrophysical agents, ice etc.). Physiotherapists with post-graduate education in musculoskeletal physiotherapy are almost three times more likely to choose only research recommended treatment approaches. There is a lack of consensus in an optimal exercise programme (type, volume, duration etc.) in patients with lateral elbow tendinopathy.

CONCLUSION

Despite research recommendations a limited use of patient rated outcome measures in lateral elbow tendinopathy is recorded. Supervised exercise is the first line treatment option for most physiotherapists, although the optimal application is still unclear. A large proportion of physiotherapists apply adjunctive treatment techniques that are either ineffective or poorly researched suggesting a substantial evidence-to-practice gap. Better access to knowledge, organisational and peer-support can potentially help to bridge this gap.

Role of strengthening during nonoperative treatment of lateral epicondyle tendinopathy

INTRODUCTION

Lateral epicondyle tendinopathy (LET) is the most common cause of lateral elbow pain. The literature on rehabilitation of the condition encompasses a plethora of interventions with most current evidence indicating that stretches and some form of strengthening are vital components. However, patient outcomes are infrequently reported further than 12 weeks from the start of therapy and it is unclear which components of a home exercise program are necessary to alleviate symptoms up to one year from the initiation of a therapy program.

PURPOSE OF THE STUDY

The purpose of the study is to determine if a therapy program with 4 to 6 visits spaced out over 12 weeks focusing on self-management and strengthening is more effective in reducing pain and improving function long term than the same program without strengthening, for individuals with LET.

STUDY DESIGN

This is a randomized controlled trial.

METHODS

Ninety-four patients were randomly allocated into two groups: both groups received the interventions of education in pertinent pathoanatomy, stretching, pain management through rest and icing, and activity modification. Group 1 (n = 38) was also provided with a strengthening component to the home exercise program, whereas group 2 did not (n = 21). Our primary outcome measure was pain at rest and pain with activity; our secondary measure was the level of functional impairment as measured by the quick disabilities of arm shoulder and hand. Outcome measurements were assessed at baseline, 6, 12, 24, and 52 weeks after initiation of therapy.

RESULTS

Both groups demonstrated statistically significant improvement with a moderate to large effect size in pain and function scores when compared with previous time point at 6, 12, and 24 weeks. Pain continued to decrease for both groups from 24 weeks to 52 weeks, but interestingly, there was a significant increase with moderate effect size in the quick disabilities of arm shoulder and hand score at 52 weeks when compared with week 24. No statistically significant difference was found between the two groups at any time point up to 52 weeks from the start of therapy.

CONCLUSIONS

This study demonstrates that a therapy program consisting of a low number of visits spaced out over 12 weeks based on education, stretches, activity modification, and pain management techniques is effective at reducing pain and increasing function in patients with LET. The addition of strengthening to this program did not improve outcomes. The therapy approach used in this study is consistent with the International Classification of Function guidelines and focuses on engaging patients in self-management of the condition through patient education and self-empowerment.

Evaluation of short-term and residual effects of Kinesio taping in chronic lateral epicondylitis: A randomized, double-blinded, controlled trial

BACKGROUND

Lateral epicondylitis is degenerative tendinosis of the extensor carpi radialis brevis muscle and is the most common work/sports-related chronic musculoskeletal problem affecting the elbow.

PURPOSE

This study aimed to evaluate the short term and residual effectiveness of the Kinesio taping method on pain, grip force, quality of life, and functionality.

STUDY DESIGN

Randomized, double-blinded, controlled study.

METHODS

Subjects were 50 patients diagnosed with chronic unilateral lateral epicondylitis with a symptom duration of at least 12 weeks. During the first four weeks, the study group received a true inhibitor Kinesio taping while the control group received sham taping. In both groups, progressive stretching and strengthening exercises were given as a home program for six weeks. The primary outcome measure was the Numerical Rating Scale (NRS) for self-report of pain intensity; secondary outcome measures were Cyriax resistive muscle test evaluation, maximal grip strength, Patient- Rated Tennis Elbow Evaluation (PRTEE), and Short Form-36 (SF-36). After the treatment, patients were evaluated by the first assessor who was blinded to taping types.

RESULTS

There was a significant decrease in NRS scores overtime during the first four weeks in both groups (P < .001,) and effect sizes were large. There was no significant difference in Cyriax muscle resistance test maximal grip strength between groups (P > .05). However, there was a significant improvement in muscle strength of elbow extension and pronation in the study group detected in the intragroup analysis. Intragroup comparisons also showed a significant improvement in all subunits of the PRTEE and SF-36 except energy/vitality, social functioning, and pain in both groups (P < .05) with moderate to high effect sizes. PRTEE pain scores were significantly decreased in the study group compared to the placebo group (P < .05, d = 0.48).

CONCLUSION

The effects of Kinesio taping on muscle strength, quality of life, and function in chronic lateral epicondylitis are not superior to placebo. However, NRS scores showed that in the two weeks after Kinesio taping treatment, pain reduction persisted as a residual effect which may improve the exercise adherence and functionality.

Effectiveness of eccentric strengthening in the treatment of lateral elbow tendinopathy: A systematic review with meta-analysis

STUDY DESIGN

Meta-analysis.

INTRODUCTION

Lateral elbow tendinopathy is a common condition with an annual incidence of up to 3% of the population. Eccentric strengthening has shown promise as a method to treat lateral elbow tendinopathy, but is unclear if it is superior to other forms of treatment.

PURPOSE OF THE STUDY

The purpose of this study was to investigate the effectiveness of eccentric strengthening compared with other forms of strengthening and pain-relieving modalities on pain, strength, and function in people with lateral elbow tendinopathy.

METHODS

Five electronic databases were searched. Reference lists of selected articles were hand-searched. Outcomes were defined a priori. Meta-analyses were performed using a random effects model with standardized mean differences, test of heterogeneity, and sensitivity analyses.

RESULTS

Eight articles were included in this review. When comparing eccentric strengthening to other forms of strengthening and pain-relieving modalities, there were significant large effect size of 1.12 (CI: 0.31-1.93) and 1.22 (CI: 0.25-2.18) in reducing pain and improving function in the short-term, respectively. In long-term, results were inconclusive on all outcomes.

DISCUSSION

A treatment program using eccentric strengthening of adequate intensity and duration seemed to be most effective for treating lateral elbow tendinopathy.

CONCLUSIONS

The state of science of best care for lateral elbow tendinopathy is still in its infancy. Large, high-quality randomized controlled trials with clearly defined strengthening regime are needed to determine optimal dosage to maximize treatment effects. Recommendations were provided based on careful synthesis of findings from this review and current evidence in literature.

The impact of a hand therapy workplace-based educational approach on the management of lateral elbow tendinopathy: A randomized controlled study

BACKGROUND

Lateral elbow tendinopathy (LET) is one of the most prevalent work-related musculoskeletal conditions. Management strategies for LET rarely consider patients' work environments and have limited focus on education regarding occupational risk factors. Workplace-based rehabilitation has shown benefits in the return to work processes for injured workers with other health conditions, but no studies have investigated the impact of a workplace-based educational approach in the management of LET.

PURPOSES

First, to identify the impact of an additional workplace-based educational intervention to standard hand therapy care on the outcomes of pain, grip strength, and function. Second, to identify the effectiveness of standard hand therapy on the same clinical outcomes.

STUDY DESIGN

A randomized controlled trial.

METHODS

Forty-nine participants were randomized to the control group (n = 25) or intervention group (n == 24). The control group received standard hand therapy for 12 weeks. The intervention group received standard hand therapy for the first 12 weeks plus an additional workplace-based educational intervention, "Working Hands-ED," delivered by a hand therapist. Pain levels for provocative tests, grip strength, and function were measured using a Numeric Rating Scale, Jamar Dynamometer, and the Patient-Rated Tennis Elbow Evaluation questionnaire at baseline, weeks 6 and 12. The Patient-Specific Functional Scale was also used for the intervention group.

RESULTS

There were no statistical differences between both groups for all clinical outcomes by 12 weeks (P> .05). Pain levels for all provocative tests and Patient-Rated Tennis Elbow Evaluation scores statistically improved within both groups (P < .05), however with small effect sizes observed. The Patient-Specific Functional Scale scores statistically improved for the intervention group by 12 weeks (P < .05).

CONCLUSION

The addition of a hand therapy workplace-based intervention did not result in superior clinical outcomes for pain, grip strength, and function. The study identified that a multimodal self-management approach used by hand therapists improved their patients' pain and function regardless of whether the education was given in the clinic or the workplace.

Lateral epicondylosis: A literature review to link pathology and tendon function to tissue-level treatment and ergonomic interventions

BACKGROUND

Common treatments for lateral epicondylosis (LE) focus on tissue healing. Ergonomic advice is suggested broadly, but recommendations based on biomechanical motion parameters associated with functional activities are rarely made. This review analyzes the role of body functions and activities in LE and integrates the findings to suggest motion parameters applicable to education and interventions relevant to activities and life roles for patients.

PURPOSE

This study examines LE pathology, tendon and muscle biomechanics, and population exposure outlining potentially hazardous activities and integrates those to provide motion parameters for ergonomic interventions to treat or prevent LE. A disease model is discussed to align treatment approaches to the stage of LE tendinopathy.

STUDY DESIGN

Integrative review METHODS: We conducted in-depth searches using PubMed, Medline, and government websites. All levels of evidence were included, and the framework for behavioral research from the National Institutes of Health was used to synthesize ergonomic research.

RESULTS

The review broadened the diagnosis of LE from a tendon ailment to one affecting the enthesis of the capitellum. It reinforced the continuum of severity to encompass degeneration as well as regeneration. Systematic reviews confirmed the availability of evidence for tissue-based treatments, but evidence of well-defined harm reducing occupational interventions was scattered amongst evidence levels. Integration of biomechanical studies and population information gave insight into types of potentially hazardous activities and provided a theoretical basis for limiting hazardous exposures to wrist extensor tendons by reducing force, compression, and shearing during functional activities.

CONCLUSIONS

These findings may broaden the first treatment approach from a passive, watchful waiting into an active exploration and reduction of at-risk activities and motions. Including the findings into education modules may provide patients with the knowledge to lastingly reduce potentially hazardous motions during their daily activities, and researchers to define parameters of ergonomic interventions.

Do hand therapists have a role in workplace-based education to manage tennis elbow? Beliefs about effective treatments among Australian hand therapists and medical practitioners

BACKGROUND

Lateral elbow tendinopathy (LET), commonly known as tennis elbow, is a prevalent work-related upper extremity musculoskeletal disorder. Medical practitioners and hand therapists manage LET with commonly available clinic-based treatments, despite no sound evidence to suggest long-term relief and functional restoration for workers with LET. Workplace-based rehabilitation is effective for injured workers with other health conditions, but no studies have investigated this rehabilitation approach in the management of LET.

OBJECTIVES

(i) Identify, compare, and contrast Australian hand therapists' and medical practitioners' perceptions about the effectiveness of common treatments for LET, and (ii) obtain their views towards a hand therapist delivered workplace-based education approach.

METHODS

In this cross-sectional study, 38 medical practitioners from Western Australia and 104 hand therapists around Australia completed online surveys. Independent t-tests were used to identify between-group differences in responses.

RESULTS

Despite some between-group differences regarding the perceived effectiveness of common LET treatments, both groups believed education about LET pathology, activity modification, postures, and workplace recommendations were most effective. Most medical practitioners (81%) and hand therapists (71%) believed workplace-based education delivered by a hand therapist would be beneficial for patients with acute and chronic LET.

CONCLUSION

Australian hand therapists and medical practitioners believed educational approaches were the most important component in the management of LET, and supported workplace-based educational interventions provided by hand therapists in the management of LET.

Carpal Tunnel Syndrome: A National Survey to Monitor Knowledge and Operating Methods

The aim of this article was to investigate the knowledge, management, and clinical practice of Italian physiotherapists concerning patients with carpal tunnel syndrome (CTS). A national cross-sectional survey consisted of 24 questions was administered from December 2019 until February 2020. A Chi-squared independence test was run to study any difference between subgroups of the sample and responses to the questionnaire. Five hundred and eight respondents completed the survey. Most respondents (n = 225/508; 44.3%) are under 29 years old, female (n = 256/508; 50.4%) and have been working as physiotherapists for less than 5 years (n = 213/508; 41.9%). Most of respondents correctly knows about the cause (n = 455/508, 89.6%), main signs and symptoms of CTS (n = 415/508, 81.70%) and administer education, manual therapy, myofascial techniques and therapeutic exercises (n = 457/508, 89.88%). Three hundred and sixty-four (71.68%) respondents were aware of the influence of psychosocial factors on the patient’s outcomes. The survey showed greater adherence to evidences by physiotherapists holding a master’s degree. The results are mostly comparable with other surveys structured all over the world on the same topic. Italian physiotherapists management of the CTS was not always in line with current evidence. Interventions such as education, manual therapy, therapeutic exercise, nerve and tendon glide techniques are widely used, while the orthotic is only offered by half of the sample.

The short-term effectiveness of low-level laser, phonophoresis, and iontophoresis in patients with lateral epicondylosis

STUDY DESIGN

Randomized parallel group trial.

INTRODUCTION

Various treatment options for lateral epicondylosis have been reported in the literature.

PURPOSE OF STUDY

We aimed to compare the effectiveness of low-level laser therapy (LLLT), phonophoresis, and iontophoresis in terms of pain, function, and grip strength.

METHODS

This study that comprised 37 patients with lateral epicondylosis was planned as a prospective randomized parallel group trial. Twelve participants were randomized to the LLLT group, 12 to the phonophoresis group, and 13 to the iontophoresis group. The Visual Analog Scale (VAS), pressure algometer, the Patient-Rated Tennis Elbow Evaluation, and grip strength dynamometer were used to measure outcomes. The measurements were performed at baseline and at the end of 15 sessions.

RESULTS

Investigation of the pain scores revealed that all VAS scores were improved in both the laser and iontophoresis groups (VAS at rest: P = .015, effect size (ES) = 1.49 and P = .016, ES = 0.58, respectively; VAS during activity: P = .008, ES = 1.05 and P = .008, ES = 1.16, respectively; VAS at night: P = .013, ES = 1.01 and P = .016, ES = 0.72, respectively). Only advance in function and grip strength was associated with the iontophoresis group (Patient-Rated Tennis Elbow Evaluation P = .006, ES = 0.78; grip strength with elbow extension P = .011, ES = 1.03; with elbow flexion P = .003, ES = 0.52).

DISCUSSION

The most effective approach could not be highlighted among the existing studies in the literature as they were applied in combination with other therapies.

CONCLUSION

In our study, we observed that LLLT provides a benefit only for pain, whereas iontophoresis is beneficial for both pain and function. If the effect size is evaluated, LLLT is more influential than iontophoresis for decreasing pain. However, when we compared phonophoresis and iontophoresis in terms of effectiveness, we found that iontophoresis has better effects for pain, function, and grip strength.

Pragmatic Combinations of Acupuncture Points for Lateral Epicondylalgia are Unreliable in the Physiotherapy Setting

This study describes the reliability of pragmatic combinations of acupuncture points for lateral epicondylalgia (LE) as prescribed by physiotherapists who were experts in acupuncture. Raters (n = 14; 33-59 years) independently prescribed acupuncture points for 30 simulated human patients with LE who were surveyed via a printed questionnaire. The frequency and cooccurrence of acupuncture points prescribed for patients with lateral epicondylitis were assessed. Absolute agreement and Light's kappa (κ_Light) with 95% confidence interval (CI) were used to quantify the interrater agreement. Raters prescribed 103 unique acupuncture points in different combinations with a median (min-max) of 5 (0-11) acupuncture points. The most prescribed acupuncture point was LI-11 (297 of 420; 71%), and the most common cooccurring acupuncture points were LI-11 and LI-4 (160 of 420; 38%). The absolute agreement for prescribing the acupuncture points ranged from 70% (point GB-20) to 0% (points LI-10, SP-6, LI-11, GB-34, LI-12, and LI-4). Point LR-3 showed the highest interrater reliability for prescribing the acupuncture points [κ_Light = 0.112, 95% CI = (0.055-0.194)], whereas point LI-4 showed the lowest reliability [κ_Light = -0.003, 95% CI = (-0.024 to 0.024)]. These findings suggest that pragmatic prescriptions of acupuncture points for LE are unreliable among physiotherapists who are experts in acupuncture. Explicit, high-level evidence-based rules for prescribing and teaching combinations of acupuncture points for LE are warranted.

Effect of wrist and finger flexion in relation to strain on the tendon origin of the extensor carpi radialis brevis: A cadaveric study simulating stretching exercises

BACKGROUND

Stretching exercises based on wrist flexion-ulnar deviation with elbow extension, forearm pronation, and additional index or middle finger flexion have been used to stretch the wrist extensors for lateral epicondylitis. The purpose of this study was to quantify the strain on the tendon origin of the extensor carpi radialis brevis in cadaver specimens during these stretching exercises.

METHODS

We used 8 fresh frozen/thawed cadaveric upper extremities. The strain on the extensor carpi radialis brevis tendon origin was measured by the addition of 4 types of traction (no traction, wrist flexion-ulnar deviation, and index or middle finger flexion in combination with wrist flexion-ulnar deviation) in 7 sequential elbow flexion angles during forearm pronation. Two types of varus stress load to the elbow (none, gravity on the forearm) were also applied.

FINDINGS

A significant increase in strain was obtained by wrist traction with 0°, 15° and 30° of elbow flexion (P<0.05). The strain was also significantly increased by adding finger traction (P<0.05) and varus stress load (P<0.05). A maximum strain value of 5.30 (SD 1.73) % was obtained when traction on the middle finger in combination with traction of the wrist was added at 15° elbow flexion with varus stress load.

INTERPRETATION

The present study provides data about the amount of strain on the extensor carpi radialis brevis tendon during stretching exercises of the wrist and finger extensors. The results of this study could be applied to stretching exercises for patients with lateral epicondylitis.

Multimodal approach to rehabilitation of the patients with lateral epicondylosis: a case series

Purpose

The objective of this study was to evaluate the effectiveness of mobilization with movement and kinesiotherapy in the treatment of patients with lateral epicondylosis.

Methods

This cases series included eight volunteers who had chronic lateral epicondylosis. The patients were treated with stretching, massage deep transverse at the lateral epicondyle and mobilization with movement associated with eccentric exercise. The mobilization with movement that consisted of a force of lateral glide of the proximal forearm. We performed twelve sessions, twice a week for 45 min/session. All patients underwent an evaluation with a visual analog scale and functional assessment through questionnaires patient-rated tennis elbow evaluation (PRTEE) and disabilities of the arm, shoulder and hand (DASH), before and after the treatment. Data were analyzed by student’s t test (p < 0.05).

Results

The results showed statistical differences in pain symptoms before and after treatment, in the analysis and functional assessment through both questionnaires comparing the pre and post treatment.

Conclusion

The data obtained in this study demonstrates improvement of the function and pain status of the sample investigated.

The immediate effects of soft tissue mobilization versus therapeutic ultrasound for patients with neck and arm pain with evidence of neural mechanosensitivity: a randomized clinical trial

STUDY DESIGN

Randomized clinical trial.

OBJECTIVES

To investigate the immediate effects of soft tissue mobilization (STM) versus therapeutic ultrasound (US) in patients with neck and arm pain who demonstrate neural mechanical sensitivity.

BACKGROUND

While experts have suggested that individuals with neck and arm pain associated with neural tissue mechanical sensitivity may benefit from STM, there has been little research to investigate this hypothesis.

METHODS

Twenty-three patients with neck and arm pain and a positive upper limb neurodynamic test (ULNT) were randomly assigned to receive STM or therapeutic US during a single session. Outcome measures were collected immediately before and after treatment, and at 2-4 day follow-up. Primary outcomes were the Global Rating of Change (GROC), range of motion (ROM) during the ULNT, and pain rating during the ULNT. Secondary measures included the Neck Disability Index (NDI), Patient-Specific Functional Scale (PSFS), Numeric Pain Rating Scale (NPRS), and active range of shoulder abduction motion combined with the wrist neutral or wrist extension.

RESULTS

A greater proportion of patients in the STM group reported a significant improvement on the GROC immediately after treatment (P = 0·003, STM = 75%, US = 9%), and at 2-4 day follow-up (P = 0·027, STM = 58%, US = 9%). Patients who received STM demonstrated greater improvements in ROM during ULNT (P = 0·026), PSFS (P = 0·007), and shoulder active ROM combined with wrist extension (P = 0·028). Improvements in Numeric Pain Rating Scale and pain during the ULNT were observed only in the STM group. There was no difference between groups for the NDI or shoulder abduction ROM with wrist neutral.

CONCLUSION

Patients with neck and arm pain demonstrated greater improvements in ULNT ROM, GROC, and PSFS, and pain following STM than after receiving therapeutic US.

LEVEL OF EVIDENCE

Therapy, level 1b.

Cross-cultural adaptation and psychometric testing of the Arabic version of the Patient-Rated Wrist Hand Evaluation (PRWHE-A) in Saudi Arabia

PURPOSES

The purposes of this study was to 1) perform a cross-cultural Arabic translation for the Patient-Rated Wrist and Hand Evaluation (PRWHE-A) using standardized guidelines and, 2) to test the psychometrics properties of the translated measure.

METHODS

A total of 48 patients with variety of hand disabilities, a mean age of 47 ± 16 years were recruited and assessed two times. The intraclass correlation coefficient (ICC) was used for assessing test-retest reliability of the PRWHE-A and its subscales while Cronbach's alpha (CA) was used for assessing the internal consistency. Construct validity was assessed by examining the strength of the correlation between the PRWHE-A and the Arabic version of the Disability of the Arm, Shoulder and Hand (DASH-A).

RESULTS

The PRWHE-A demonstrated excellent test-retest reliability (ICC= 0.97) and internal consistency (CA= 0.96). The DASH-A demonstrated moderately to low correlation (r= 0.64) with the PRWHE-A.

CONCLUSIONS

The results of this study indicated that PRWHE-A is a reliable and valid assessment tool and can be used in patients with different wrist/hand disabilities whose primary language is Arabic.

Efficacy of low-level laser therapy associated to orthoses for patients with carpal tunnel syndrome: A randomized single-blinded controlled trial

OBJECTIVE

Compare the efficacy of orthoses and patient education with and without the addition to Low-Level Laser Therapy (LLLT - 660 nm, 30 mW, a continuous regime and bean area of 0.06 cm2). The laser irradiation was delivered with the fluency of 10J/cm2 in patients with mild and moderate Carpal Tunnel Syndrome (CTS).

METHODS

48 patients were randomized and 30 finished the protocol (a sample loss of 37.5%), 90% female and 10% males. Randomization was applied to allocate the patients in each one of the groups, with association or not to LLLT (group orthoses or LLLT and orthoses). All of them were submitted to ergonomic home orientations. The short-term symptoms and function outcome were assessed through: Boston Carpal Tunnel Questionnaire (BCTQ) - Severity of Symptoms (SS) Functional Score (FS). Pain (VAS), Semmes-Weinstein monofilaments, 2PD and pinch strength was used for characterization of the sample. Most of the participants were women, over 4th decade enrolled on heavy hand duties occupations, right-handed, 66.7% affected on dominant hand, without alterations in sensory median nerve thresholds or pinch strength.

RESULTS

Both groups showed a reduction of total BCTQ score and its subdomains after six weeks, with significant difference (p< 0.05), comparing to baseline. No significant difference was found between groups. A Minimal clinical change was observed after the intervention in 92.3% of participants for BCTQ subdomain severity of symptoms at individual comparison for LLLT and orthoses group and 76.5% for the orthoses group, demonstrating clinical relevance. Effect size Cohen's index was moderate for the severity of symptoms.

CONCLUSION

LLLT in association to orthoses and ergonomic orientation seems to be effective in short-term symptoms relieve for patients with mild and moderate CTS.

The influence of different non-articular proximal forearm orthoses (brace) widths in the wrist extensors muscle activity, range of motion and grip strength in healthy volunteers

PURPOSE

The purpose this study was perform a biomechanical evaluation to compare the influence of commercial models of different non-articular proximal forearm orthoses widths (2.5 cm, 5.5 cm, 7.5 cm and 12.0 cm) in the extensor muscle activation, range of motion and grip strength in healthy subjects.

METHODS

Was analyzed data from extensor carpi radialis, extensor carpi ulnares and extensor digitorum comunis using surface electromyography, simultaneous with a wrist electrogoniometer MiotecTM and a hydraulic dynamometer JamarTM. The sequence of tests with all the commercial orthoses models was randomized. Statistics analyses were performed by linear model with mixed effects.

RESULTS

According to our findings the non-articular proximal forearm orthoses (2.5 cm - narrowest) positioned close to lateral epicondyle provided lesser muscle activation on extensor carpi radialis brevis/longus and extensor digitorum comunis, decreased wrist extension and grip strength during submaximal grip task (p< 0.01).

CONCLUSIONS

A narrow non-articular proximal forearm orthosis positioned close to the lateral epicondyle might decrease the extensor muscle activation and therefore could reduce mechanical stress on its insertion, based on this sample. Clinical studies must be conducted to confirm these findings.

Evidence-Based Approach to Treating Lateral Epicondylitis Using the Occupational Adaptation Model

The occupational therapy Centennial Vision reinforces the importance of informing consumers about the benefit of occupational therapy and continuing to advocate for the unique client-centered role of occupational therapy. Occupational therapy practitioners working in hand therapy have traditionally found it difficult to combine the biomechanical foundations of hand therapy with the fundamental client-centered tenets of occupational therapy. Embracing our historical roots will become more important as health care evolves and third-party payers continue to scrutinize the need for the profession of occupational therapy. This article outlines a client-centered approach for hand therapists for the treatment of lateral epicondylitis using the Occupational Adaptation Model.

Effect of simultaneous stretching of the wrist and finger extensors for lateral epicondylitis: a gross anatomical study of the tendinous origins of the extensor carpi radialis brevis and extensor digitorum communis

BACKGROUND

Pulling the wrist into flexion with the elbow in extension and forearm in pronation has been used as the stretching technique of wrist extensors for lateral epicondylitis. Simultaneous stretching of the fingers in addition to the wrist flexion has also been applied. However, the mechanism of this simultaneous stretching has not been clarified. This study is designed to clarify the mechanism underlying this simultaneous stretching technique based on the anatomical features of the origins of the extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC).

METHODS

Thirty-nine arms from formalin-embalmed Japanese human specimens were dissected. The features of the origins of the ECRB and EDC were macroscopically observed, and the locations of each origin on the lateral epicondyle were measured.

RESULTS

The ECRB had a long and wide, purely tendinous origin which originated from the anterior slope of the lateral epicondyle. The tendinous origin of the index finger of the EDC (EDC-IF) arose from the posterior aspect of the ECRB tendinous origin, with a coexisting muscular portion observed at the level of the proximal forearm. The middle finger of the EDC (EDC-MF) had a short tendinous origin with an associated muscular portion and originated proximo-laterally to the origin of the ECRB on the lateral epicondyle. In addition, the muscular origin of the EDC-MF arose on the superficial and posterior aspect of the ECRB tendinous origin. In contrast, the ring and little fingers of the EDC originated from the tendinous septum of the extensor digiti minimi and extensor carpi ulnaris, and had no connection with the ECRB tendinous origin.

CONCLUSIONS

On the basis of our anatomical findings, simultaneous stretching of the wrist extensors by wrist, index and middle fingers flexion could provide stretching force to both the tendinous origins of the ECRB and EDC through the EDC-IF and EDC-MF.

Knowledge of and willingness to recommend kinesiotape for upper limb overuse injuries: A comparison of therapists', GPs' and surgeons' perspectives

Background/Aims:

Upper limb overuse injuries, such as tennis elbow, may be challenging in terms of both diagnosis and management, and there is no consensus on a gold standard intervention. Despite limited evidence in the literature to support the efficacy of kinesiotaping, this new treatment modality has gained popularity among athletes and the general public and is commonly used to treat these conditions. Clinicians are therefore relying on lower levels of evidence and/or expert opinion when deciding whether to use this treatment and it is likely that there are varying perspectives on its potential clinical benefits. The purpose of this study was to compare the opinions of hand therapists, general practitioners (GPs) and hand surgeons on the use of kinesiotape for upper limb overuse injuries.

Methods:

This cross-sectional study used a self-report survey to gather data from respondents (n=157). Survey questions aimed to identify practice patterns and gain an understanding of clinicians' reasons for either recommending or not recommending this modality.

Results:

Hand therapists rated their understanding of the use of kinesiotape (Mean±SD = 6.51±1.89) significantly higher than levels reported by GPs (Mean±SD = 3.04± 2.50) and surgeons (Mean±SD = 4.16± 2.52). Hand therapists reported a moderate level of success with the use of kinesiotape (Mean±SD = 6.30±1.59), which was significantly higher than that reported by surgeons (Mean±SD = 4.84±1.21); however, there was no notable difference between hand therapists and GPs (Mean±SD = 5.27± 2.10). Of the three groups, GPs were most likely (69.5%) to indicate that they would not use or recommend kinesiotape, compared with 31% of hand therapists and 38.7% of hand surgeons.

Conclusions:

Hand therapists are more likely to rate kinesiotaping as successful and recommend its clinical use, indicating that they place greater emphasis on their own clinical experience than research evidence. It is inferred that GPs and surgeons have a higher level of scepticism for interventions without supporting evidence, such as kinesiotaping. More evidence from randomised controlled trials is required to inform practitioners on the potential benefits of this intervention.

Influence of volar and dorsal static orthoses in different wrist positions on muscle activation and grip strength in healthy subjects

Introduction

Orthoses are indicated for injuries of the wrist, although there is weak evidence for its influence on extensor muscle activation patterns. The purpose of this study was to compare two designs of volar and dorsal wrist orthoses in several positions, from flexion to extension, by surface electromyography wrist extensor muscle activation and grip strength in healthy subjects.

Methods

We analysed extensor carpi radialis brevis and longus, extensor carpi ulnaris and extensor digitorum comunis muscle activity by surface electromyography. The volunteers performed maximum and submaximum (50%) isometric grips, which were evaluated with a Jamar™ dynamometer using volar and dorsal orthoses with several positions of the wrist (0°, 15° and 30°), both in flexion and extension ( p < 0.05).

Results

Our results showed a significant decrease in extensor muscle activation at 15° and 30° of wrist extension in both volar and dorsal orthoses at 100% and 50% of maximum task. A decrease was also found at rest at 15° of wrist flexion volar orthoses. Decreased grip strength was found at 15° and 30° of wrist flexion in both volar and dorsal orthoses.

Conclusions

Based on the results of this sample, we would suggest, as orthotic prescriptions, 15° or 30° wrist extension orthoses as a supporting therapeutic modality for performance in new studies with lateral epicondylitis in association with low-intensity grip activity; or 15° of wrist flexion volar orthoses for rest, depending on the chronicity of the disease and individual assessment. Future studies with symptomatic patients are needed to confirm these findings.

Development and Initial Validation of the Satisfaction and Recovery Index (SRI) for Measurement of Recovery from Musculoskeletal Trauma

Background:

There is a need for a generic patient-reported outcome (PRO) that is patient-centric and offers sound properties for measuring the process and state of recovery from musculoskeletal trauma. This study describes the construction and initial validation of a new tool for this purpose.

Methods:

A prototype tool was constructed through input of academic and clinical experts and patient representatives. After evaluation of individual items, a 9-item Satisfaction and Recovery Index (SRI) was subject to psychometric evaluation drawn from classical test theory. Subjects were recruited through online and clinical populations, from those reporting pain or disability from musculoskeletal trauma. The full sample (N = 129) completed the prototype tool and a corresponding region-specific disability measure. A subsample (N = 46) also completed the Short-Form 12 version 2 (SF12vs). Of that, a second subsample (N = 29) repeated all measures 3 months later.

Results:

A single factor ‘health-related satisfaction’ was extracted that explained 71.1% of scale variance, Cronbach’s alpha = 0.95. A priori hypotheses for cross-sectional correlations with region-specific disability measures and the generic Short-form 12 component scores were supported. The SRI tool was equally responsive to change, and able to discriminate between recovered/non-recovered subjects, at a level similar to that of the region-specific measures and generally better than the SF-12 subscales.

Conclusion:

The new SRI tool, as a measure of health-related satisfaction, shows promise in this initial evaluation of its properties. It is generic, patient-centered, and shows overall measurement properties similar to that of region-specific measures while allowing the potential benefit of comparison between clinical conditions. Despite early promising results, additional properties need to be explored before the tool can be endorsed for routine clinical use.

Is eccentric exercise an effective treatment for lateral epicondylitis? A systematic review

OBJECTIVE

To establish the effectiveness of eccentric exercise as a treatment intervention for lateral epicondylitis.

DATA SOURCES

ProQuest, Medline via EBSCO, AMED, Scopus, Web of Science, CINAHL.

REVIEW METHODS

A systematic review was undertaken to identify randomized and controlled clinical trials incorporating eccentric exercise as a treatment for patients diagnosed with lateral epicondylitis. Studies were included if: they incorporated eccentric exercise, either in isolation or as part of a multimodal treatment protocol; they assessed at least one functional or disability outcome measure; and the patients had undergone diagnostic testing. The methodological quality of each study was assessed using the Modified Cochrane Musculoskeletal Injuries Group score sheet.

RESULTS

Twelve studies met the inclusion criteria. Three were deemed 'high' quality, seven were 'medium' quality, and two were 'low' quality. Eight of the studies were randomized trials investigating a total of 334 subjects. Following treatment, all groups inclusive of eccentric exercise reported decreased pain and improved function and grip strength from baseline. Seven studies reported improvements in pain, function, and/or grip strength for therapy treatments inclusive of eccentric exercise when compared with those excluding eccentric exercise. Only one low-quality study investigated the isolated effects of eccentric exercise for treating lateral epicondylitis and found no significant improvements in pain when compared with other treatments.

CONCLUSION

The majority of consistent findings support the inclusion of eccentric exercise as part of a multimodal therapy programme for improved outcomes in patients with lateral epicondylitis.

A potential classification model for individuals with tennis elbow

The complexities associated with the anatomy, biomechanics, and pathophysiology of lateral epicondylalgia have resulted in numerous treatment options for this common overuse syndrome. Choosing an appropriate treatment option from such an array can be challenging. To assist therapists with this challenge, these authors created a classification model that categorizes patients by using information from common signs and symptoms. Such categorization can assist therapists in identifying appropriate treatment options

Effectiveness of different methods of resistance exercises in lateral epicondylosis--a systematic review

STUDY DESIGN

Systematic Review.

INTRODUCTION

Lateral epicondylosis (LE) is relatively common with an annual incidence in the general population of 1% to 3%. Systematic reviews have identified exercise is effective, but have not established specific exercise parameters.

PURPOSE

The purpose of this systematic review was to synthesize the quality and content of clinical research addressing type and dosage of resistance exercises in lateral epicondylosis.

METHODS

Computerized bibliographic databases (1990-2010) were searched using relevant keywords; bibliographies of included papers were hand searched. Of 594 screened abstracts, 11 articles (12 studies) met inclusion criteria. Articles were randomly allocated to pairs of reviewers who independently verified data extraction and appraised the full text, using a structured critical appraisal tool with 24 items. Data extraction was limited by a lack of consistent reporting of elements of exercise dosage.

RESULTS

The mean quality rating of the studies was 72%, with 2 papers exceeding 75% quality. Of the 12 studies, 9 addressed the effects of isotonic (eccentric/concentric) exercises, 2 studied the effect of isometric and one studied isokinetic exercises. The exercise programs ranged over a period of 4 to 52 weeks. Exercises were prescribed 1 to 6 times per day, with an average duration of 15 minutes per session, and average of 15 repetitions (range: 3 to 50), with 1 to 4 sets per session.

CONCLUSION

All the studies reported that resistance exercise resulted in substantial improvement in pain and grip strength; eccentric exercise was most studied. Strengthening using resistance exercises is effective in reducing pain and improving function for lateral epicondylosis but optimal dosing is not defined.
