Manual Therapy Versus Surgery for Carpal Tunnel Syndrome: 4-Year Follow-Up From a Randomized Controlled Trial.

OBJECTIVE: No study to our knowledge has investigated the effects longer than 1 year of manual therapy in carpal tunnel syndrome (CTS). The purpose of this study was to investigate the effects of manual therapy versus surgery at 4-year follow-up and to compare the post-study surgery rate in CTS. METHODS: This randomized controlled trial was conducted in a tertiary public hospital and included 120 women with CTS who were randomly allocated to manual therapy or surgery. The participants received 3 sessions of physical therapy, including desensitization maneuvers of the central nervous system or carpal tunnel release combined with a tendon/nerve gliding exercise program at home. Primary outcome was pain intensity (mean and the worst pain). Secondary outcomes included functional status, symptom severity, and self-perceived improvement measured using a global rating of change scale. Outcomes for this analysis were assessed at baseline, 1 year, and 4 years. The rate of surgical intervention received by each group was assessed throughout the study. RESULTS: At 4 years, 97 (81%) women completed the study. Between-group changes for all outcomes were not significantly different at 1 year (mean pain: mean difference [MD] = -0.3, 95% CI = -0.9 to 0.3; worst pain: MD = -1.2, 95% CI = -3.6 to 1.2; function: MD = -0.1, 95% CI = -0.4 to 0.2; symptom severity: MD = -0.1, 95% CI = -0.3 to 0.1) and 4 years (mean pain: MD = 0.1, 95% CI = -0.2 to 0.4; worst pain: MD = 0.2, 95% CI = -0.8 to 1.2; function: MD = 0.1, 95% CI = -0.1 to 0.3; symptom severity: MD = 0.2, 95% CI = -0.2 to 0.6). Self-perceived improvement was also similar in both groups. No between-group differences (15% physical therapy vs 13% surgery) in surgery rate were observed during the 4 years. CONCLUSIONS: In the long term, manual therapy, including desensitization maneuvers of the central nervous system, resulted in similar outcomes and similar surgery rates compared with surgery in women with CTS. Both interventions were combined with a tendon/nerve gliding exercise program at home. IMPACT: This is the first study to our knowledge to report clinical outcomes and surgical rates during a 4-year follow-up and will inform decisions regarding surgical versus conservative management of CTS. LAY SUMMARY: Women with CTS may receive similar benefit from a more conservative treatment-manual therapy-as they would from surgery.

Effective self-stretching of carpal ligament for the treatment of carpal tunnel syndrome: A double-blinded randomized controlled study.

INTRODUCTION: Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome worldwide. There are limited studies on the effectiveness of carpal ligament stretching on symptomatic and electrophysiologic outcomes. PURPOSE OF THE STUDY: The purpose of this study was to evaluate the effect of self-myofascial stretching of the carpal ligament on symptom outcomes and nerve conduction findings in persons with CTS. STUDY DESIGN: This is a prospective, double-blinded, randomized, placebo-controlled trial. METHODS: Eighty-three participants diagnosed with median mononeuropathy across the wrist by nerve conduction study were randomized 1:1 to sham treatment or self-carpal ligament stretching. Participants were instructed to perform the self-treatment four times a day for six weeks. Seventeen participants in the sham treatment group and 19 participants in the carpal ligament stretching group completed the study. Pre- and post-treatment outcome measures included subjective complaints, strength, nerve conduction findings, and functional scores. RESULTS: Groups were balanced on age, sex, hand dominance, symptom duration, length of treatment, presence of nocturnal symptoms, and compliance with treatment. Even though the ANOVA analyses were inconclusive about group differences, explorative post hoc analyses revealed significant improvements in numbness (P = .011, Cohen's d = .53), tingling (P = .007, Cohen's d = .60), pinch strength (P = .007, Cohen's d = -.58), and symptom severity scale (P = .007, Cohen's d = .69) for the treatment group only. CONCLUSIONS: The myofascial stretching of the carpal ligament showed statistically significant symptom improvement in persons with CTS. Larger comparative studies that include other modalities such as splinting should be performed to confirm the effectiveness of this treatment option.

Effects of diacutaneous fibrolysis in patients with mild to moderate symptomatic carpal tunnel syndrome: a randomized controlled trial.

OBJECTIVE:: To compare the effects of diacutaneous fibrolysis with sham in patients with mild to moderate carpal tunnel syndrome. DESIGN:: Double-blind (patient and evaluator) randomized controlled trial. SETTING:: Miguel Servet University Hospital, Zaragoza, Spain. SUBJECTS:: A total of 52 patients (72 wrists) with carpal tunnel syndrome, 41 women and 11 men, mean age was 46.9 (8.8) years. They were divided into two groups: diacutaneous fibrolysis group and sham group. INTERVENTIONS:: Real diacutaneous fibrolysis in diacutaneous fibrolysis group and sham diacutaneous fibrolysis in sham group. Both groups received five sessions in the forearm, wrist and hand. MAIN MEASURES:: Neurophysiological parameters assessed at baseline and at the end of the treatment. Intensity of nocturnal symptoms (visual analogue scale (VAS)) and upper limb functional capacity (Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire) at baseline, at the end of the treatment and one month after treatment. RESULTS:: Diacutaneous fibrolysis group (n = 30 wrists) improved in nerve conduction distal motor latency (mean difference: -0.26, 95% confidence interval (CI): -0.49/-0.26), sensory conduction velocity (mean difference: 6.52, 95% CI: 3.52/9.51), intensity of nocturnal symptoms (mean difference: -2.24, 95% CI: -4.08/-2.04) and upper limb functional capacity (mean difference: -19, 95% CI: -26.1/-11.9) compared to the sham group (n = 30 wrists) ( P < 0.02, P < 0.01, P < 0.01 and P < 0.01, respectively). At one-month follow-up, improvements in the nocturnal symptoms and upper limb functional capacity were maintained compared to the sham group ( P < 0.01). CONCLUSION:: Diacutaneous fibrolysis provides short-term and one-month follow-up, improvements in sensory conduction velocity, motor distal latency, symptoms and functional capacity in patients with mild to moderate carpal tunnel syndrome.

Neurodynamic Techniques Versus "Sham" Therapy in the Treatment of Carpal Tunnel Syndrome: A Randomized Placebo-Controlled Trial.

OBJECTIVE: To evaluate the efficacy of neurodynamic techniques used as the sole therapeutic component compared with sham therapy in the treatment of mild and moderate carpal tunnel syndromes (CTS). DESIGN: Single-blinded, randomized placebo-controlled trial. SETTING: Several medical clinics. PARTICIPANTS: Volunteer sample of patients (N=250) diagnosed with CTS (n=150). INTERVENTIONS: Neurodynamic techniques were used in the neurodynamic techniques group, and sham therapy was used in the sham therapy group. In the neurodynamic techniques group, neurodynamic sequences were used, and sliding and tension techniques were also used. In the sham therapy group, no neurodynamic sequences were used, and therapeutic procedures were performed in an intermediate position. Therapy was conducted twice weekly for a total of 20 therapy sessions. MAIN OUTCOME MEASURES: Symptom severity (symptom severity scale) and functional status (functional status scale) of the Boston Carpal Tunnel Questionnaire. RESULTS: A baseline assessment revealed no intergroup differences in all examined parameters (P>.05). After therapy, there was statistically significant intragroup improvement in nerve conduction study (sensory and motor conduction velocity and motor latency) only for the neurodynamic techniques group (P<.01). After therapy, intragroup statistically significant changes also occurred for the neurodynamic techniques group in pain assessment, 2-point discrimination sense, symptom severity scale, and functional status scale (in all cases P<.01). There were no group differences in assessment of grip and pinch strength (P>.05). CONCLUSIONS: The use of neurodynamic techniques has a better therapeutic effect than sham therapy in the treatment of mild and moderate forms of CTS.

Carpal Tunnel Syndrome: Effectiveness of Physical Therapy and Electrophysical Modalities. An Updated Systematic Review of Randomized Controlled Trials.

OBJECTIVE: To review scientific literature studying the effectiveness of physical therapy and electrophysical modalities for carpal tunnel syndrome (CTS). DATA SOURCES: The Cochrane Library, PubMed, Embase, CINAHL, and Physiotherapy Evidence Database. STUDY SELECTION: Two reviewers independently applied the inclusion criteria to select potential eligible studies. DATA EXTRACTION: Two reviewers independently extracted the data and assessed the methodologic quality using the Cochrane Risk of Bias Tool. DATA SYNTHESIS: A best-evidence synthesis was performed to summarize the results of the included studies (2 reviews and 22 randomized controlled trials [RCTs]). For physical therapy, moderate evidence was found for myofascial massage therapy versus ischemic compression on latent, or active, trigger points or low-level laser therapy in the short term. For several electrophysical modalities, moderate evidence was found in the short term (ultrasound vs placebo, ultrasound as single intervention vs other nonsurgical interventions, ultrasound vs corticosteroid injection plus a neutral wrist splint, local microwave hyperthermia vs placebo, iontophoresis vs phonophoresis, pulsed radiofrequency added to wrist splint, continuous vs pulsed vs placebo shortwave diathermy, and interferential current vs transcutaneous electrical nerve stimulation vs a night-only wrist splint). In the midterm, moderate evidence was found in favor of radial extracorporeal shockwave therapy (ESWT) added to a neutral wrist splint, in favor of ESWT versus ultrasound, or cryo-ultrasound, and in favor of ultrasound versus placebo. For all other interventions studied, only limited, conflicting, or no evidence was found. No RCTs investigating the long-term effects of physical therapy and electrophysical modalities were found. Because of heterogeneity in the treatment parameters used in the included RCTs, optimal treatment parameters could not be identified. CONCLUSIONS: Moderate evidence was found for several physical therapy and electrophysical modalities for CTS in the short term and midterm. Future studies should concentrate on long-term effects and which treatment parameters of physical therapy and electrophysical modalities are most effective for CTS.

Carpal Tunnel Syndrome: Physical Therapy or Surgery?

Carpal tunnel syndrome causes pain, numbness, and weakness in the wrist and hand. Nearly 50% of all work-related injuries are linked to carpal tunnel syndrome, and people with this injury are more likely to miss work because of it. Patients with carpal tunnel syndrome can be treated with physical therapy or surgery. Although surgery may be considered when the symptoms are severe, more than a third of patients do not return to work within 8 weeks after an operation. Based on the potential side effects and risks of surgery, patients often ask if they might try physical therapy first. An article in the March 2017 issue of JOSPT assesses the effectiveness of therapy and surgery to treat carpal tunnel syndrome. J Orthop Sports Phys Ther 2017;47(3):162. doi:10.2519/jospt.2017.0503.

The Effectiveness of Manual Therapy Versus Surgery on Self-reported Function, Cervical Range of Motion, and Pinch Grip Force in Carpal Tunnel Syndrome: A Randomized Clinical Trial.

Study Design Randomized parallel-group trial. Background Carpal tunnel syndrome (CTS) is a common pain condition that can be managed surgically or conservatively. Objective To compare the effectiveness of manual therapy versus surgery for improving self-reported function, cervical range of motion, and pinch-tip grip force in women with CTS. Methods In this randomized clinical trial, 100 women with CTS were randomly allocated to either a manual therapy (n = 50) or a surgery (n = 50) group. The primary outcome was self-rated hand function, assessed with the Boston Carpal Tunnel Questionnaire. Secondary outcomes included active cervical range of motion, pinch-tip grip force, and the symptom severity subscale of the Boston Carpal Tunnel Questionnaire. Patients were assessed at baseline and 1, 3, 6, and 12 months after the last treatment by an assessor unaware of group assignment. Analysis was by intention to treat, with mixed analyses of covariance adjusted for baseline scores. Results At 12 months, 94 women completed the follow-up. Analyses showed statistically significant differences in favor of manual therapy at 1 month for self-reported function (mean change, -0.8; 95% confidence interval [CI]: -1.1, -0.5) and pinch-tip grip force on the symptomatic side (thumb-index finger: mean change, 2.0; 95% CI: 1.1, 2.9 and thumb-little finger: mean change, 1.0; 95% CI: 0.5, 1.5). Improvements in self-reported function and pinch grip force were similar between the groups at 3, 6, and 12 months. Both groups reported improvements in symptom severity that were not significantly different at all follow-up periods. No significant changes were observed in pinch-tip grip force on the less symptomatic side and in cervical range of motion in either group. Conclusion Manual therapy and surgery had similar effectiveness for improving self-reported function, symptom severity, and pinch-tip grip force on the symptomatic hand in women with CTS. Neither manual therapy nor surgery resulted in changes in cervical range of motion. Level of Evidence Therapy, level 1b. Prospectively registered September 3, 2014 at www.clinicaltrials.gov (NCT02233660). J Orthop Sports Phys Ther 2017;47(3):151-161. Epub 3 Feb 2017. doi:10.2519/jospt.2017.7090.

The effectiveness of passive physical modalities for the management of soft tissue injuries and neuropathies of the wrist and hand: a systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration.

OBJECTIVE: The purpose of this systematic review was to determine the effectiveness of passive physical modalities compared to other interventions, placebo/sham interventions, or no intervention in improving self-rated recovery, functional recovery, clinical outcomes and/or administrative outcomes (eg, time of disability benefits) in adults and/or children with soft tissue injuries and neuropathies of the wrist and hand. METHODS: We systematically searched MEDLINE, EMBASE, PsycINFO, and the Cochrane Central Register of Controlled Trials, accessed through Ovid Technologies, Inc, and CINAHL Plus with Full Text, accessed through EBSCO host, from 1990 to 2015. Our search strategies combined controlled vocabulary relevant to each database (eg, MeSH for MEDLINE) and text words relevant to our research question and the inclusion criteria. Randomized controlled trials, cohort studies, and case-control studies were eligible. Random pairs of independent reviewers screened studies for relevance and critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with low risk of bias were synthesized following best evidence synthesis principles. RESULTS: We screened 6618 articles and critically appraised 11 studies. Of those, 7 had low risk of bias: 5 addressed carpal tunnel syndrome (CTS) and 2 addressed de Quervain disease. We found evidence that various types of night splints lead to similar outcomes for the management of CTS. The evidence suggests that a night wrist splint is less effective than surgery in the short term but not in the long term. Furthermore, a night wrist splint and needle electroacupuncture lead to similar outcomes immediately postintervention. Finally, low-level laser therapy and placebo low-level laser therapy lead to similar outcomes. The evidence suggests that kinesio tape or a thumb spica cast offers short-term benefit for the management of de Quervain disease. Our search did not identify any low risk of bias studies examining the effectiveness of passive physical modalities for the management of other soft tissue injuries or neuropathies of the wrist and hand. CONCLUSIONS: Different night orthoses provided similar outcomes for CTS. Night orthoses offer similar outcomes to electroacupuncture but are less effective than surgery in the short term. This review suggests that kinesio tape or a thumb spica cast may offer short-term benefit for the management of de Quervain disease.

Manual Physical Therapy Versus Surgery for Carpal Tunnel Syndrome: A Randomized Parallel-Group Trial.

UNLABELLED: This randomized clinical trial investigated the effectiveness of surgery compared with physical therapy consisting of manual therapies including desensitization maneuvers in carpal tunnel syndrome (CTS). The setting was a public hospital and 2 physical therapy practices in Madrid, Spain. One hundred twenty women with CTS were enrolled between February 2013 and January 2014, with 1-year follow-up completed in January 2015. Interventions consisted of 3 sessions of manual therapies including desensitization maneuvers of the central nervous system (physical therapy group, n = 60) or decompression/release of the carpal tunnel (surgical group, n = 60). The primary outcome was pain intensity (mean pain and the worst pain), and secondary outcomes included functional status and symptoms severity subscales of the Boston Carpal Tunnel Questionnaire and the self-perceived improvement. They were assessed at baseline and 1, 3, 6, and 12 months by a blinded assessor. Analysis was by intention to treat. At 12 months, 111 (92%) women completed the follow-up (55/60 physical therapy, 56/60 surgery). Adjusted analyses showed an advantage (all, P < .01) for physical therapy at 1 and 3 months in mean pain (Δ -2.0 [95% confidence interval (CI) -2.8 to -1.2]/-1.3 [95% CI -2.1 to -.6]), the worst pain (Δ -2.9 [-4.0 to -2.0]/-2.0 [-3.0 to -.9]), and function (Δ -.8 [-1.0 to -.6]/-.3 [-.5 to -.1]), respectively. Changes in pain and function were similar between the groups at 6 and 12 months. The 2 groups had similar improvements in the symptoms severity subscale of the Boston Carpal Tunnel Questionnaire at all follow-ups. In women with CTS, physical therapy may result in similar outcomes on pain and function to surgery. TRIAL REGISTRATION: http://www.clinicaltrials.gov, ClinicalTrials.gov, NCT01789645. PERSPECTIVE: This study found that surgery and physical manual therapies including desensitization maneuvers of the central nervous system were similarly effective at medium-term and long-term follow-ups for improving pain and function but that physical therapy led to better outcomes in the short term.

Massage therapy as an effective treatment for carpal tunnel syndrome.

Carpal tunnel syndrome is a common peripheral entrapment that causes neuralgia in the median nerve distribution of the hand. The primary aim of this study was to evaluate the efficacy of massage therapy as a treatment for carpal tunnel syndrome. Within this process, the locations of trigger-points that refer neuropathy to the hand were identified. The creation of massage pressure tables provides a means of treatment reproducibility. Twenty-one participants received 30 min of massage, twice a week, for six weeks. Carpal tunnel questionnaires, the Phalen, Tinel, and two-point discrimination tests provided outcome assessment. The results demonstrated significant (p < 0.001) change in symptom severity and functional status from two weeks. Based on this study, the combination of massage and trigger-point therapy is a viable treatment option for carpal tunnel syndrome and offers a new treatment approach.

Response of pain intensity to soft tissue mobilization and neurodynamic technique: a series of 18 patients with chronic carpal tunnel syndrome.

OBJECTIVE: The purpose of this prospective case series was to examine the combined effects of soft tissue mobilization and nerve slider neurodynamic technique on pain and pressure sensitivity in women with chronic carpal tunnel syndrome (CTS). METHODS: Eighteen women with a clinical and electromyographic diagnosis of CTS participated. Patients completed the numerical pain rating scale (NPRS) for current, worst, and lowest pain intensity and underwent pain pressure threshold (PPT) testing over the median, radial, and ulnar nerves; the C5-C6 zygapophyseal joint; the carpal tunnel; and the tibialis anterior muscle. Pain was assessed at baseline and 1-week follow-up, whereas PPT were assessed at baseline and immediately after and 1-week after intervention. Each received soft tissue mobilization and nerve slider neurodynamic technique directed at different anatomical sites of potential entrapment of the median nerve. RESULTS: A decrease in the mean current intensity and worst level of hand pain (P<.01) was found 1 week after the treatment session (mean changes, 2.2±1.1 points). A treatment effect for PPT levels over the C5-C6 zygapophyseal joint (P<.001) was found: PPT increased bilaterally 1 week after the intervention. No other significant changes in PPT levels were found (P>.195). CONCLUSIONS: The application of soft tissue mobilization and neurodynamic technique decreased the intensity of pain but did not change pressure pain sensitivity in this group of women with chronic CTS.

Randomized controlled trial comparing acupuncture with placebo acupuncture for the treatment of carpal tunnel syndrome.

OBJECTIVE: To investigate the efficacy of acupuncture for the treatment of mild to moderate carpal tunnel syndrome (CTS). DESIGN: Prospective, randomized, placebo-controlled, double-blinded study. SETTING: Single-center study. PARTICIPANTS: Forty-one acupuncture-naïve adult subjects with mild to moderate CTS enrolled in the study. Thirty-four subjects completed the study. METHODS: Clinical diagnosis of CTS was supported by electrodiagnostic findings. Subjects were randomly assigned to either (1) acupuncture (n = 21) or (2) placebo acupuncture (n = 20) with use of Streitberger placebo acupuncture needles. Both groups received weekly sessions of acupuncture for 6 weeks. Wrist braces were provided to both groups to wear at night, and compliance was monitored. MAIN OUTCOME MEASUREMENTS: The primary outcome measurement was subject-reported change in the Carpal Tunnel Self Assessment Questionnaire (CTSAQ) Symptom and Function scales immediately after and at 2 weeks and 3 months after the final treatment. The secondary outcomes included tip and key pinch strength and combined sensory index. RESULTS: Compared with pretreatment baseline values, subjects in the acupuncture group had 0.58 improvement (P = .03) on the CTSAQ Symptom scale score at 3 months after the last treatment, whereas 0.81 improvement (P = .001) was noted in the placebo acupuncture group. No statistically significant difference was found between the groups treated with acupuncture and placebo acupuncture with respect to improvement in CTS symptoms, function, tip/key pinch, or combined sensory index. CONCLUSIONS: To our knowledge, this study is the first randomized, placebo-controlled, double-blinded prospective study of traditional acupuncture for CTS. Both the treatment and placebo groups demonstrated improvements from baseline. Acupuncture was not shown to be superior to placebo acupuncture when used in conjunction with bracing for patients with mild to moderate CTS.

Immediate and long-term effects of selected physiotherapy methods in patients with carpal tunnel syndrome.

BACKGROUND: Carpal tunnel syndrome is a serious therapeutic problem and it considerably impairs the patients' quality of life. Despite many studies, the effectiveness of conservative treatment is still debatable. This study aimed to evaluate the immediate and long-term effects of conservative treatment involving ultrasound therapy combined with massage and kinesiotherapy for carpal tunnel syndrome. MATERIAL AND METHODS: A total of 61 patients with carpal tunnel syndrome were assessed with regard to such symptoms as pain, numbness, tingling sensation, morning stiffness, and self-care difficulties. We used provocation tests and investigated sensory impairments, autonomic disturbances, and Lüthy's sign. Conduction in the median nerve fibres was assessed during a nerve conduction study. We performed computer-aided measurement of the hand joint range of motion and global grip strength. The tests were conducted before and on completion of a rehabilitation programme. The hands were re-examined one year later. The treatment involved ultrasound therapy, massage, and kinesiotherapy. RESULTS: The treatment outcomes confirmed the effectiveness of the therapeutic programme. Significant improvements concerning the majority of the symptoms were observed between the first and second examination as well for the entire follow-up period. We observed significant improvement in the quality of sensation, the hand range of motion and muscle strength. CONCLUSIONS: Ultrasound therapy combined with massage and kinesiotherapy brings the expected, long-term effects in patients with carpal tunnel syndrome.

Quantification of the effects of transcutaneous electrical nerve stimulation with functional magnetic resonance imaging: a double-blind randomized placebo-controlled study.

OBJECTIVE: To evaluate the effects of transcutaneous electric nerve stimulation (TENS) by using functional magnetic resonance imaging (fMRI) in patients with carpal tunnel syndrome (CTS). DESIGN: Randomized controlled trial. SETTINGS: University medical center and an outpatient imaging center. PARTICIPANTS: Female patients with CTS (n=20) were randomized into 2 groups receiving either TENS (n=10) or sham TENS (n=10). In both groups, an initial baseline fMRI session was performed via stimulating digits 2, 5, and 3 in turn, 1 scan run for each. TENS versus sham TENS treatment was given, and a repeat imaging was performed starting 20 minutes after the treatment as follows: second finger on the 20th minute, fifth finger on the 25th minute (ulnar nerve innervated control finger), and third finger on the 30th min. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Differences in fMRI activation between the 2 groups were evaluated. RESULTS: Our results demonstrated that 20 to 25 minutes after TENS treatment-but not in the sham TENS group-a significant fMRI signal decrease for digit 2 (post-TENS vs baseline) was observed in the secondary somatosensory regions, ipsilateral primary motor cortex (M1), contralateral supplementary motor cortex (SMA), contralateral parahippocampal gyrus, contralateral lingual gyrus, and bilateral superior temporal gyrus. Measurements on the 25th to 30th minutes for digit 5 were similar between the groups, with presence of activities in areas other than generally activated regions because of painful stimuli. Thirty to 35 minutes after TENS treatment, a significant fMRI signal decrease for digit 3 was detected in the contralateral M1 and contralateral SMA only in the TENS group. CONCLUSIONS: Our findings showed that TENS treatment significantly decreased the pain-related cortical activations caused by stimulation of the median nerve-innervated fingers up to 35 minutes after treatment.

WITHDRAWN: Ergonomic and physiotherapeutic interventions for treating work-related complaints of the arm, neck or shoulder in adults.

BACKGROUND: Conservative interventions such as physiotherapy and ergonomic adjustments (such as keyboard adjustments or ergonomic advice) play a major role in the treatment of most work-related complaints of the arm, neck or shoulder (CANS). OBJECTIVES: This systematic review aims to determine whether conservative interventions have a significant impact on outcomes for work-related CANS in adults. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (March 2005) and Cochrane Rehabilitation and Related Therapies Field Specialised Register (March 2005), the Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2005), PubMed, EMBASE, CINAHL, AMED and reference lists of articles. The date of the last search was March 2005. No language restrictions were applied. SELECTION CRITERIA: We included randomised controlled trials studying conservative interventions (e.g. exercises, relaxation, physical applications, biofeedback, myofeedback and work-place adjustments) for adults suffering CANS. DATA COLLECTION AND ANALYSIS: Two authors independently selected trials from the search yield, assessed the methodological quality using the Delphi list, and extracted relevant data. We pooled data or, in the event of clinical heterogeneity or lack of data, we used a rating system to assess levels of evidence. MAIN RESULTS: For this update we included six additional studies; 21 trials in total. Seventeen trials included people with chronic non-specific neck or shoulder complaints, or non-specific upper extremity disorders. Over 25 interventions were evaluated; five main subgroups of interventions could be determined: exercises, manual therapy, massage, ergonomics, and energised splint. Overall, the quality of the studies was poor.In 14 studies a form of exercise was evaluated, and contrary to the previous review we now found limited evidence about the effectiveness of exercises when compared to massage and conflicting evidence when exercises are compared to no treatment. In this update there is limited evidence for adding breaks during computer work; massage as add-on treatment on manual therapy, manual therapy as add-on treatment on exercises; and some keyboard designs when compared to other keyboards or placebo in participants with carpal tunnel syndrome. AUTHORS' CONCLUSIONS: There is limited evidence for the effectiveness of keyboards with an alternative force-displacement of the keys or an alternative geometry, and limited evidence for the effectiveness of exercises compared to massage; breaks during computer work compared to no breaks; massage as an add-on treatment to manual therapy; and manual therapy as an add-on treatment to exercises.

Longitudinal excursion and strain in the median nerve during novel nerve gliding exercises for carpal tunnel syndrome.

Nerve and tendon gliding exercises are advocated in the conservative and postoperative management of carpal tunnel syndrome (CTS). However, traditionally advocated exercises elongate the nerve bedding substantially, which may induce a potentially deleterious strain in the median nerve with the risk of symptom exacerbation in some patients and reduced benefits from nerve gliding. This study aimed to evaluate various nerve gliding exercises, including novel techniques that aim to slide the nerve through the carpal tunnel while minimizing strain ("sliding techniques"). With these sliding techniques, it is assumed that an increase in nerve strain due to nerve bed elongation at one joint (e.g., wrist extension) is simultaneously counterbalanced by a decrease in nerve bed length at an adjacent joint (e.g., elbow flexion). Excursion and strain in the median nerve at the wrist were measured with a digital calliper and miniature strain gauge in six human cadavers during six mobilization techniques. The sliding technique resulted in an excursion of 12.4 mm, which was 30% larger than any other technique (p

AUTHORS' CONCLUSIONS: There is limited evidence for the effectiveness of keyboards with an alternative force-displacement of the keys or an alternative geometry, and limited evidence for the effectiveness of exercises compared to massage; breaks during computer work compared to no breaks; massage as an add-on treatment to manual therapy; and manual therapy as an add-on treatment to exercises.

Ergonomic and physiotherapeutic interventions for treating upper extremity work related disorders in adults.

BACKGROUND: Conservative interventions such as physiotherapy and ergonomic adjustments play a major part in the treatment of most work-related musculoskeletal disorders (WRMD). OBJECTIVES: The objective of this systematic review is to determine whether conservative interventions have a significant impact on short and long-term outcomes for upper extremity WRMD in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised register (January 2002) and Cochrane Rehabilitation and Related Therapies Field specialised register (January 2002), the Cochrane Controlled Trials Register (The Cochrane Library Issue 3, 2001), PubMed (1966 to November 2001), EMBASE (1988 to November 2001), and CINAHL (1982 to November 2001). We also searched the Physiotherapy Index (1988 to November 2001) and reference lists of articles. No language restrictions were applied. SELECTION CRITERIA: Only randomised controlled trials and concurrent controlled trials studying conservative interventions for adults suffering from upper extremity WRMD were included. Conservative interventions may include exercises, relaxation, physical applications, biofeedback, myofeedback and work place adjustments. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected the trials from the search yield and assessed the clinical relevance and methodological quality using the Delphi list. In the event of clinical heterogeneity or lack of data we used a rating system to assess levels of evidence. MAIN RESULTS: We included 15 trials involving 925 people. Twelve trials included people with chronic non-specific neck or shoulder complaints, or non-specific upper extremity disorders. Over 20 interventions were evaluated; seven main subgroups of interventions could be determined: exercises, manual therapy, massage, ergonomics, multidisciplinary treatment, energised splint and individual treatment versus group therapy. Overall, the quality of the studies appeared to be poor. In 10 studies a form of exercise was evaluated, and there is limited evidence about the effectiveness of exercises only when compared to no treatment. Concerning manual therapy (1 study), massage (4 studies), multidisciplinary treatment (1 study) and energised splint (1 study) no conclusions can be drawn. Limited evidence is found concerning the effectiveness of specific keyboards for patients with carpal tunnel syndrome. REVIEWER'S CONCLUSIONS: This review shows limited evidence for the effectiveness of keyboards with an alternative force-displacement of the keys or an alternative geometry, and limited evidence for the effectiveness of individual exercises. The benefit of expensive ergonomic interventions (such as new chairs, new desks etc) in the workplace is not clearly demonstrated.
