Comparison of a targeted and general massage protocol on strength, function, and symptoms associated with carpal tunnel syndrome: a randomized pilot study

Effect of three traditional conservative treatment techniques on patients with mild-to-moderate carpal tunnel syndrome: A systematic review and meta-analysis

BACKGROUND

Carpal tunnel syndrome (CTS) is a common peripheral nerve entrapment syndrome that can be treated in a variety of ways, including manual therapy, massage, and acupuncture.

PURPOSE

Traditional conservative treatment techniques have been widespread used for treatment of patients with mild-to-moderate carpal tunnel syndrome (CTS), such as manual therapy, massage, and acupuncture. However, there appears to be no consensus about the benefits of traditional conservative treatment techniques for patients with CTS. This systematic review and meta-analysis were aimed to analyze the effectiveness of three traditional conservative treatment techniques (manual therapy, massage, and acupuncture) on the patients with mild-to-moderate CTS.

STUDY DESIGN

Intervention systematic review with meta-analysis.

METHODS

Randomized controlled clinical trails were searched from the inception of PubMed, Web of Science and CNKI up to May 22, 2024. Mean differences (MD) or standardized mean differences (SMD) were used as effect sizes by us and 95% confidence intervals (CI) were used to analyze these studies. Analyses were performed using RevMan 5.3 software. Funnel plots and Egger's test were used to assess publication bias.

RESULTS

A total of 14 articles with 1110 patients with mild-to-moderate CTS satisfied the inclusion criteria in this systematic review and meta-analysis. The meta-analysis found that the three traditional conservative treatment techniques can significantly reduce the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) [MD = -1.55, 95% CI (-2.15, -0.95), p < 0.00001], Symptom Severity Scale (SSS) [MD = -0.90, 95% CI (-1.28, -0.51), p < 0.00001], Functional Status Scale (FSS) [MD = -0.85, 95% CI (-1.17, -0.54), p < 0.00001] and pain [SMD = -2.03, 95% CI (-2.75, -1.30), p < 0.00001] scores, and improve sensory nerve conduction velocity (SNCV) [MD = 5.37, 95% CI (2.43, 8.32), P = 0.0004] compared with the control group.

CONCLUSIONS

This study demonstrated that three traditional conservative treatment techniques can effectively improve the severity of symptoms, functional status, pain levels, and sensory nerve conduction velocity on patients with mild-to-moderate CTS.

Integrated manual therapies: IASP taskforce viewpoint

Introduction

Manual therapy refers to a range of hands-on interventions used by various clinical professionals, such as osteopaths, osteopathic physicians, chiropractors, massage therapists, physiotherapists, and physical therapists, to treat patients experiencing pain.

Objectives

To present existing evidence of mechanisms and clinical effectiveness of manual therapy in pain.

Methods

This Clinical Update focuses on the 2023 International Association for the Study of Pain Global Year for Integrative Pain Care. Current models of manual therapy and examples of integrative manual therapy are discussed.

Results

The evolution of concepts in recent years are presented and current gaps in knowledge to guide future research highlighted. Mechanisms of manual therapy are discussed, including specific and contextual effects. Findings from research on animal and humans in manual therapy are presented including on inflammatory markers, fibrosis, and behaviours. There is low to moderate levels of evidence that the effect sizes for manual therapy range from small to large for pain and function in tension headache, cervicogenic headache, fibromyalgia, low back pain, neck pain, knee pain, and hip pain.

Conclusion

Manual therapies appear to be effective for a variety of conditions with minimal safety concerns. There are opportunities for manual therapies to integrate new evidence in its educational, clinical, and research models. Manual therapies are also well-suited to fostering a person-centred approach to care, requiring the clinician to relinquish some of their power to the person consulting. Integrated manual therapies have recently demonstrated a fascinating evolution illustrating their adaptability and capacity to address contemporary societal challenges.

Diacutaneous Fibrolysis Intervention in Patients with Mild to Moderate Carpal Tunnel Syndrome May Avoid Severe Cases in Elderly: A Randomized Controlled Trial

BACKGROUND

Carpal Tunnel Syndrome (CTS) mainly affects adults of working age. The prevalence of severe cases is higher in elderly patients (>65 years old). Clinical guidelines recommend conservative treatment as the best option in the initial stages of CTS to avoid severe cases. Diacutaneous Fibrolysis (DF) has demonstrated to improve nerve conduction studies and mechanosensitivity. The main purpose was to quantify changes in the cross-sectional area (CSA) of the median nerve, transversal carpal ligament (TCL) thickness, numbness intensity, and the subjective assessment of clinical change after DF treatment in patients with CTS.

METHODS

a double-blind, randomized, placebo-controlled trial was designed. A number of 44 patients (60 wrists) with CTS were randomized to the DF group or the sham group. CSA and TCL thickness variables were registered by ultrasound. Clinical variables were assessed by the visual analogue scale and GROC scale. SPSS version 24.0 for MAC was used for statistical analysis. The group by time interaction between groups was analyzed using two-way repeated measures analysis of variance.

RESULTS

The DF group reduced CSA with a mean of 0.45 mm² (IC 95% 0.05 to 0.86) and TCL thickness with a mean reduction of 0.4 mm (IC 95% 0.6 to 2.1) compared to the sham group (p < 0.01, p < 0,03, respectively). Additionally, the DF group decreased the numbness intensity with a mean reduction of 3.47 (IC 95% 2.50 to 4.44, p < 0.01) and showed a statistically significant improvement on the GROC scale (p < 0.01).

CONCLUSIONS

DF treatment may significantly reduce CSA and TCL thickness, numbness intensity, and improved clinical perspective. DF applied in patients with mild to moderate CTS may prevent the progression of the disease as they age.

[Physiotherapy and sports therapeutic interventions for treatment of carpal tunnel syndrome : A systematic review]

BACKGROUND

The treatment of carpal tunnel syndrome (CTS) usually involves surgical decompression of the nerve or splinting and additional medication. Physiotherapy and sports therapy could be non-invasive and alternative treatment approaches with a simultaneous low risk of side effects.

OBJECTIVE

The review systematically summarizes the current studies on the effectiveness of physiotherapy and sports therapeutic interventions for treatment of CTS and focuses on the reduction of symptoms and, as a secondary outcome, improvement of hand function.

MATERIAL AND METHODS

The systematic review includes randomized controlled trials reporting on physiotherapy or sports therapy interventions published prior to February 2021 in the electronic databases PubMed, CINAHL and Web of Science. Following the guidelines of preferred reporting items for systematic reviews and meta-analyses (PRISMA) and the Cochrane Collaboration, a systematic search of the literature, data extraction and evaluation of the risk of bias using the Cochrane risk of bias tool were conducted by two independent researchers.

RESULTS

Out of 461 identified studies 26 were included in the qualitative analysis. The risk of bias in the individual studies was graded as moderate to low. Potential bias might arise due to inadequate blinding of patients and study personnel in some cases as well as due to selective reporting of study results and procedures. Manual therapy proved to be faster and equally effective in reducing pain and improving function in the long term compared to surgery. Mobilization techniques, massage techniques, kinesiotaping and yoga as therapeutic interventions also showed positive effects on symptoms.

CONCLUSION

For the management of mild to moderate CTS, physiotherapy and sports therapeutic interventions are characterized primarily by success after as little as 2 weeks of treatment as well as comparable success to surgery and 3 months of postoperative treatment. In addition, patients are not exposed to surgical risks. The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) with the number 42017073839.

Therapeutic role of yoga in neuropsychological disorders

Yoga is considered a widely-used approach for health conservation and can be adopted as a treatment modality for a plethora of medical conditions, including neurological and psychological disorders. Hence, we reviewed relevant articles entailing various neurological and psychological disorders and gathered data on how yoga exerts positive impacts on patients with a diverse range of disorders, including its modulatory effects on brain bioelectrical activities, neurotransmitters, and synaptic plasticity. The role of yoga practice as an element of the treatment of several neuropsychological diseases was evaluated based on these findings.

Key indicators of repetitive overuse-induced neuromuscular inflammation and fibrosis are prevented by manual therapy in a rat model

BACKGROUND

We examined the effectiveness of a manual therapy consisting of forearm skin rolling, muscle mobilization, and upper extremity traction as a preventive treatment for rats performing an intensive lever-pulling task. We hypothesized that this treatment would reduce task-induced neuromuscular and tendon inflammation, fibrosis, and sensorimotor declines.

METHODS

Sprague-Dawley rats performed a reaching and lever pulling task for a food reward, 2 h/day, 3 days/week, for 12 weeks, while simultaneously receiving the manual therapy treatment 3 times per week for 12 weeks to either the task-involved upper extremities (TASK-Tx), or the lower extremities as an active control group (TASK-Ac). Results were compared to similarly treated control rats (C-Tx and C-Ac).

RESULTS

Median nerves and forearm flexor muscles and tendons of TASK-Ac rats showed higher numbers of inflammatory CD68+ and fibrogenic CD206+ macrophages, particularly in epineurium, endomysium and epitendons than TASK-Tx rats. CD68+ and CD206+ macrophages numbers in TASK-Tx rats were comparable to the non-task control groups. TASK-Ac rats had more extraneural fibrosis in median nerves, pro-collagen type I levels and immunoexpression in flexor digitorum muscles, and fibrogenic changes in flexor digitorum epitendons, than TASK-Tx rats (which showed comparable responses as control groups). TASK-Ac rats showed cold temperature, lower reflexive grip strength, and task avoidance, responses not seen in TASK-Tx rats (which showed comparable responses as the control groups).

CONCLUSIONS

Manual therapy of forelimbs involved in performing the reaching and grasping task prevented the development of inflammatory and fibrogenic changes in forearm nerves, muscle, and tendons, and sensorimotor declines.

Manual therapy prevents onset of nociceptor activity, sensorimotor dysfunction, and neural fibrosis induced by a volitional repetitive task

Painful and disabling musculoskeletal disorders remain prevalent. In rats trained to perform repetitive tasks leading to signs and dysfunction similar to those in humans, we tested whether manual therapy would prevent the development of the pathologies and symptoms. We collected behavioral, electrophysiological, and histological data from control rats, rats that trained for 5 weeks before performing a high-repetition high-force (HRHF) task for 3 weeks untreated, and trained rats that performed the task for 3 weeks while being treated 3x/week using modeled manual therapy (MMT) to the forearm (HRHF + MMT). The MMT included bilateral mobilization, skin rolling, and long axis stretching of the entire upper limb. High-repetition high-force rats showed decreased performance of the operant HRHF task and increased discomfort-related behaviors, starting after training. HRHF + MMT rats showed improved task performance and decreased discomfort-related behaviors compared with untreated HRHF rats. Subsets of rats were assayed for presence or absence of ongoing activity in C neurons and slow Aδ neurons in their median nerves. Neurons from HRHF rats had a heightened proportion of ongoing activity and altered conduction velocities compared with control and MMT-treated rats. Median nerve branches in HRHF rats contained increased numbers of CD68 macrophages and degraded myelin basic protein, and showed increased extraneural collagen deposition, compared with the other groups. We conclude that the performance of the task for 3 weeks leads to increased ongoing activity in nociceptors, in parallel with behavioral and histological signs of neuritis and nerve injury, and that these pathophysiologies are largely prevented by MMT.

Immediate improvements of supination range of motion and strength following pronator teres muscle friction massage: a clinical trial comparing people with and without supination limited motion

OBJECTIVES

To investigate the effects of friction massage techniques on the pronator teres muscle on supination range of motion (ROM) and supinator strength in individuals with and without limited supination ROM.

METHODS

In total, 26 subjects (13 with limited supination ROM and 13 healthy subjects) volunteered to participate in this study. We used a customized wrist cuff. Supination ROM and supinator strength were measured with a 9-axis inertial motion sensor and load cell. The friction massage protocol was executed with the pronator teres muscle in a relaxed position. Then supination ROM and supinator strength were measured again.

RESULTS

There was no significant interaction effect on supination ROM, which was significantly greater in the limited supination and control groups. A post hoc t-test revealed that the limited supination group achieved a significantly increased post-test supination ROM (51.7 ± 7.8°) compared to the pre-test value (43.6 ± 5.2°). In addition, the control group achieved a significant increase in post-test supination ROM (67.7 ± 10.0°) compared to the pre-test value (61.4 ± 7.7°). There was no significant interaction effect on supinator strength. Supinator strength was significantly greater in the limited supination and control groups. A post hoc t-test revealed a significant difference in supinator strength between the pre- and post-test values in the limited supination group.

DISCUSSION

Friction massage helps restore a limited ROM of the forearm supination motion and immediately increases supinator muscle strength. This technique can be used as an intervention method to improve muscle strength in patients with limited supination ROM.

Model structure for protocol adherence utilizing a manualized therapeutic massage intervention

Background The Protocol Training and Assessment Model (Model) was developed through collaboration between Emory University School of Medicine and Atlanta School of Massage to minimize intra- and inter-therapist variability for two research massage therapist (rMT) applied intervention arms in the Massage for Cancer-Related Fatigue (MCRF) early-phase study. The Model was followed to maintain and assess protocol integrity for the study's manualized Swedish massage therapy (SMT) and light touch (LT) interventions. Methods The Model includes initial rMT training, quarterly retraining sessions, accessible resources (scripts, treatment guides, weekly research personnel meetings), and ongoing monitoring. Model efficacy was assessed by monitoring data collected at retraining sessions, through audio recording review, and through subject and rMT reporting. Results Model application resulted in a high level of intervention consistency throughout the study. Protocol-related session comment rate by subjects was 2.7%. Few study participants reported intra-rMT or inter-rMT treatment delivery differences. Observation during retraining sessions indicated massage therapists continued to adhere to protocols. Importantly rMTs increased their participation beyond core duties, suggesting additional ways to standardize subject treatment experience. Conclusions Through systematic application of the Protocol Training and Assessment Model, continuous and collaborative quality improvement discussions between scientists and research massage therapists resulted in reliable, standardized SMT and LT interventions for the MCRF early-phase study. Future research can apply the Model to support and assess consistent rMT-delivered intervention applications.

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.

A structured literature synthesis of wrist outcome measures: An evidence-based approach to determine use among common wrist diagnoses

STUDY DESIGN

Structured literature synthesis.

INTRODUCTION

Hand therapists and researchers have numerous options when selecting outcome measures for patients with wrist pathologies. An evidence-based approach to determining which measures are used most often can inform choices.

PURPOSE OF THE STUDY

To describe how frequently outcome measures are used in recent randomized controlled trials of patients with wrist diagnoses. Identifying assessment design and related International Classification of Functioning, Disability and Health (ICF) domains provides additional consideration for selection.

METHODS

Systematic PubMed and Cumulative Index to Nursing and Allied Health Literature searches for the time frame between January 2005 and March 2015 captured measures used in randomized controlled trials researching wrist-specific fractures, ligament injuries, nerve injuries, arthritis/arthroplasty, or stress injuries/wrist pain.

RESULTS

Three most frequent measures used within each diagnostic category are detailed with assessment design described and ICF domain identified. Across diagnoses, grip/pinch strength and Disabilities of Arm, Shoulder and Hand were the most frequently used physical and patient-reported outcome measures, respectively. The Jebsen-Taylor Hand Function Test was the most frequently used performance measure.

DISCUSSION AND CONCLUSIONS

Consideration of the evidence, ICF domains, wrist diagnoses, and assessment design can help hand therapists select the measure most appropriate for use.

Effectiveness of manual therapy versus surgery in pain processing due to carpal tunnel syndrome: A randomized clinical trial

BACKGROUND

People with carpal tunnel syndrome (CTS) exhibit widespread pressure pain and thermal pain hypersensitivity as a manifestation of central sensitization. The aim of our study was to compare the effectiveness of manual therapy versus surgery for improving pain and nociceptive gain processing in people with CTS.

METHODS

The trial was conducted at a local regional Hospital in Madrid, Spain from August 2014 to February 2015. In this randomized parallel-group, blinded, clinical trial, 100 women with CTS were randomly allocated to either manual therapy (n = 50), who received three sessions (once/week) of manual therapies including desensitization manoeuvres of the central nervous system, or surgical intervention (n = 50) group. Outcomes including pressure pain thresholds (PPT), thermal pain thresholds (HPT or CPT), and pain intensity which were assessed at baseline, and 3, 6, 9 and 12 months after the intervention by an assessor unaware of group assignment. Analysis was by intention to treat with mixed ANCOVAs adjusted for baseline scores.

RESULTS

At 12 months, 95 women completed the follow-up. Patients receiving manual therapy exhibited higher increases in PPT over the carpal tunnel at 3, 6 and 9 months (all, p < 0.01) and higher decrease of pain intensity at 3 month follow-up (p < 0.001) than those receiving surgery. No significant differences were observed between groups for the remaining outcomes.

CONCLUSIONS

Manual therapy and surgery have similar effects on decreasing widespread pressure pain sensitivity and pain intensity in women with CTS. Neither manual therapy nor surgery resulted in changes in thermal pain sensitivity.

SIGNIFICANCE

The current study found that manual therapy and surgery exhibited similar effects on decreasing widespread pressure pain sensitivity and pain intensity in women with carpal tunnel syndrome at medium- and long-term follow-ups investigating changes in nociceptive gain processing after treatment in carpal tunnel syndrome.

The Immediate Effects of Manual Massage of Forearm on Power-Grip Strength and Endurance in Healthy Young Men

OBJECTIVE

The purpose of this study was to examine the immediate effects of a single massage session on hand grip strength and endurance after isometric exercise in healthy young men under controlled conditions.

METHODS

A total of 44 healthy young men from a university population participated in the study. They were randomized to receive either massage or passive movement intervention. Hand grip endurance and hand grip strength in both groups were recorded using a Jamar hand grip dynamometer and a digital chronometer before and after the intervention. Statistical analysis was performed using the Wilcoxon, Mann-Whitney, and paired t test as well as independent t test.

RESULTS

Pre-and postmean hand grip endurance times for the massage group were 38.4 ± 12 and 46.5 ± 13 seconds (P < .001), and hand grip strength values were 43 ± 5.6 and 45.7 ± 5.3 kg (P = .077). Pre-and postmean hand grip endurance times for the passive movement group were 33 ± 12.3 and 31.9 ± 10.7 seconds (P = .513), and hand grip strength values were 42.8 ± 6 and 42.9 ± 5.6 kg (P = .854).

CONCLUSION

Immediately after 1 session of massage to the forearm and hand, the grip endurance improved in a group of healthy young men. However, passive movement of the upper limb for 1 session did not enhance grip performance.

Prediction of Outcome in Women With Carpal Tunnel Syndrome Who Receive Manual Physical Therapy Interventions: A Validation Study

Study Design Secondary analysis of a randomized trial. Background A clinical prediction rule to identify patients with carpal tunnel syndrome (CTS) most likely to respond to manual physical therapy has been published but requires further testing to determine its validity. Objective To assess the validity of a clinical prediction rule proposed for the management of patients with CTS in a different group of patients with a variety of treating clinicians. Methods A preplanned secondary analysis of a randomized controlled trial investigating the efficacy of manual physical therapies, including desensitization maneuvers of the central nervous system, in 120 women suffering from CTS was performed. Patients were randomized to receive 3 sessions of manual physical therapy (n = 60) or surgical release/decompression of the carpal tunnel (n = 60). Self-perceived improvement with a global rating of change was recorded at 6- and 12-month follow-ups. Pain intensity (mean pain and worst pain on a 0-to-10 numeric pain-rating scale) and scores on the Boston Carpal Tunnel Questionnaire (functional status and symptom severity subscales) were assessed at baseline and at 1, 3, 6, and 12 months. A baseline assessment of status on the clinical prediction rule was performed (positive status on the clinical prediction rule was defined as meeting at least 2 of the following criteria: pressure pain threshold of less than 137 kPa over the affected C5-6 joint; heat pain threshold of less than 39.6°C over the affected carpal tunnel; and general health score [Medical Outcomes Study 36-Item Short-Form Health Survey] of greater than 66 points). Linear mixed models with repeated measures were used to examine the validity of the rule. Results Participants with a positive status on the rule who received manual physical therapy did not experience greater improvements compared to those with a negative status on the rule for mean pain (P = .65), worst pain (P = .86), function (P = .99), or symptom severity (P = .85). Further, the clinical prediction rule performed no better than chance in identifying the individuals with CTS most likely to respond to manual physical therapy or surgery (mean pain, P = .87; worst pain, P = .91; function, P = .60; severity, P = .66). No differences in self-perceived improvement were observed at either 6 (P = .68) or 12 (P = .36) months, according to the rule. Conclusion The results of this study did not support the validity of the previously developed clinical prediction rule for manual physical therapy in women with CTS. Level of Evidence Prognosis, level 1b. J Orthop Sports Phys Ther 2016;46(6):443-451. Epub 23 Mar 2016. doi:10.2519/jospt.2016.6348.

Manual therapy as an effective treatment for fibrosis in a rat model of upper extremity overuse injury

Key clinical features of carpal tunnel syndrome and other types of cumulative trauma disorders of the hand and wrist include pain and functional disabilities. Mechanistic details remain under investigation but may involve tissue inflammation and/or fibrosis. We examined the effectiveness of modeled manual therapy (MMT) as a treatment for sensorimotor behavior declines and increased fibrogenic processes occurring in forearm tissues of rats performing a high repetition high force (HRHF) reaching and grasping task for 12 weeks. Young adult, female rats were examined: food restricted control rats (FRC, n=12); rats that were trained for 6 weeks before performing the HRHF task for 12 weeks with no treatment (HRHF-CON, n=11); and HRHF task rats received modeled manual therapy (HRHF-MMT, n=5) for 5 days/week for the duration of the 12-week of task. Rats receiving the MMT expressed fewer discomfort-related behaviors, and performed progressively better in the HRHF task. Grip strength, while decreased after training, improved following MMT. Fibrotic nerve and connective tissue changes (increased collagen and TGF-β1 deposition) present in 12-week HRHF-CON rats were significantly decreased in 12-week HRHF-MMT rats. These observations support the investigation of manual therapy as a preventative for repetitive motion disorders.

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

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.

The effectiveness of therapeutic massage in carpal tunnel syndrome

Background: The carpal tunnel syndrome is a neuralgia of the median nerve of the hand caused by permanent pressure which results in sensation and motion disturbances in the area. Principal symptoms include pain in the hand and wrist, numbness and tingling of the fingers, sensation dysfunctions, and finally, the limitation of mobility and manual flexibility of the hand. The discomfort leads to a significant decrease in the patient’s quality of life. In case of carpal tunnel syndrome surgical and non-surgical treatments with selected elements of physiotherapy are applied. Aim of the study: The aim of this study was to present and evaluate possible methods of treatment such as massage therapy and lymphatic drainage as the form of post-surgery treat-ment in carpal tunnel syndrome.Material and methods: The young woman with the carpal tunnel syndrome after the surgical treatment received 50-minute lymphatic drainage (three sessions) and 30-minute therapeutic massage (four sessions). The procedures were performed every two days.Results: After the application of both kinds of massage in appropriate sequence, the following changes have been notified. The swelling in the area of the hand was reduced and the patient reported definite decrease of pain.Conclusions: The massage might be one of the forms of therapy used after surgical treatment in carpal tunnel syndrome, especially when the symptoms occur. It is also often effective with other components of physiotherapy as non-surgical treatment.

Massage therapy research review

Moderate pressure massage has contributed to many positive effects including increased weight gain in preterm infants, reduced pain in different syndromes including fibromyalgia and rheumatoid arthritis, enhanced attentiveness, reduced depression and enhanced immune function (increased natural killer cells and natural killer cell activity).Surprisingly, these recent studies have not been reviewed, highlighting the need for the current review. When moderate and light pressure massage have been compared in laboratory studies, moderate pressure massage reduced depression, anxiety and heart rate, and it altered EEG patterns, as in a relaxation response. Moderate pressure massage has also led to increased vagal activity and decreased cortisol levels. Functional magnetic resonance imaging data have suggested that moderate pressure massage was represented in several brain regions including the amygdala, the hypothalamus and the anterior cingulate cortex, all areas involved in stress and emotion regulation. Further research is needed to identify underlying neurophysiological and biochemical mechanisms associated with moderate pressure massage.

A mechatronic system for quantitative application and assessment of massage-like actions in small animals

Massage therapy has a long history and has been widely believed effective in restoring tissue function, relieving pain and stress, and promoting overall well-being. However, the application of massage-like actions and the efficacy of massage are largely based on anecdotal experiences that are difficult to define and measure. This leads to a somewhat limited evidence-based interface of massage therapy with modern medicine. In this study, we introduce a mechatronic device that delivers highly reproducible massage-like mechanical loads to the hind limbs of small animals (rats and rabbits), where various massage-like actions are quantified by the loading parameters (magnitude, frequency and duration) of the compressive and transverse forces on the subject tissues. The effect of massage is measured by the difference in passive viscoelastic properties of the subject tissues before and after mechanical loading, both obtained by the same device. Results show that this device is useful in identifying the loading parameters that are most conducive to a change in tissue mechanical properties, and can determine the range of loading parameters that result in sustained changes in tissue mechanical properties and function. This device presents the first step in our effort for quantifying the application of massage-like actions used clinically and measurement of their efficacy that can readily be combined with various quantitative measures (e.g., active mechanical properties and physiological assays) for determining the therapeutic and mechanistic effects of massage therapies.

Analysis of scientific truth status in controlled rehabilitation trials

RATIONALE, AIMS AND OBJECTIVES

Systematic reviews, meta-analyses and clinical guidelines (reviews) are intended to inform clinical practice, and in this sense can be thought of as scientific truthmakers. High-quality controlled trials should align to this truth, and method quality markers should predict truth status. We sought to determine in what way controlled trial quality relates to scientific truth, and to determine predictive utility of trial quality and bibliographic markers.

METHOD

A sample of reviews in rehabilitation medicine was examined. Two scientific truth dimensions were established based on review outcomes. Quality and bibliographic markers were extracted from associated trials for use in a regression analysis of their predictive utility for trial truth status. Probability analysis was undertaken to examine judgments of future trial truth status.

RESULTS

Of the 93 trials included in contemporaneous reviews, overall, n = 45 (48%) were true. Randomization was found more in true trials than false trials in one truth dimension (P = 0.03). Intention-to-treat analysis was close to significant in one truth dimension (P = 0.058), being more commonly used in false trials. There were no other significant differences in quality or bibliographic variables between true and false trials. Regression analysis revealed no significant predictors of trial truth status. Probability analysis reported that the reasonable chance of future trials being true was between 2 and 5%, based on a uniform prior.

CONCLUSIONS

The findings are at odds with what is considered gold-standard research methods, but in line with previous reports. Further work should focus on scientific dynamics within healthcare research and evidence-based practice constructs.

Manipulative and multimodal therapy for upper extremity and temporomandibular disorders: a systematic review

OBJECTIVE

The purpose of this study was to complete a systematic review of manual and manipulative therapy (MMT) for common upper extremity pain and disorders including the temporomandibular joint (TMJ).

METHODS

A literature search was conducted using the Cumulative Index of Nursing Allied Health Literature, PubMed, Manual, Alternative, and Natural Therapy Index System (MANTIS), Physiotherapy Evidence Database (PEDro), Index to Chiropractic Literature, Google Scholar, and hand search inclusive of literature from January 1983 to March 5, 2012. Search limits included the English language and human studies along with MeSH terms such as manipulation, chiropractic, osteopathic, orthopedic, and physical therapies. Inclusion criteria required an extremity peripheral diagnosis (for upper extremity problems including the elbow, wrist, hand, finger and the (upper quadrant) temporomandibular joint) and MMT with or without multimodal therapy. Studies were assessed using the PEDro scale in conjunction with modified guidelines and systems. After synthesis and considered judgment scoring was complete, evidence grades of "A, B, C and I" were applied.

RESULTS

Out of 764 citations reviewed, 129 studies were deemed possibly to probably useful and/or relevant to develop expert consensus. Out of 81 randomized controlled or clinical trials, 35 were included. Five controlled or clinical trials were located and 4 were included. Fifty case series, reports and/or single-group pre-test post-test prospective case series were located with 32 included. There is Fair (B) level of evidence for MMT to specific joints and the full kinetic chain combined generally with exercise and/or multimodal therapy for lateral epicondylopathy, carpal tunnel syndrome, and temporomandibular joint disorders, in the short term.

CONCLUSION

The information from this study will help guide practitioners in the use of MMT, soft tissue technique, exercise, and/or multimodal therapy for the treatment of a variety of upper extremity complaints in the context of the hierarchy of published and available evidence.

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.

Exercise and mobilisation interventions for carpal tunnel syndrome

BACKGROUND

Non-surgical treatment, including exercises and mobilisation, has been offered to people experiencing mild to moderate symptoms arising from carpal tunnel syndrome (CTS). However, the effectiveness and duration of benefit from exercises and mobilisation for this condition remain unknown.

OBJECTIVES

To review the efficacy and safety of exercise and mobilisation interventions compared with no treatment, a placebo or another non-surgical intervention in people with CTS.

SEARCH METHODS

We searched the Cochrane Neuromuscular Disease Group Specialised Register (10 January 2012), CENTRAL (2011, Issue 4), MEDLINE (January 1966 to December 2011), EMBASE (January 1980 to January 2012), CINAHL Plus (January 1937 to January 2012), and AMED (January 1985 to January 2012).

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials comparing exercise or mobilisation interventions with no treatment, placebo or another non-surgical intervention in people with CTS.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed searches and selected trials for inclusion, extracted data and assessed risk of bias of the included studies. We calculated risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CIs) for primary and secondary outcomes of the review. We collected data on adverse events from included studies.

MAIN RESULTS

Sixteen studies randomising 741 participants with CTS were included in the review. Two compared a mobilisation regimen to a no treatment control, three compared one mobilisation intervention (for example carpal bone mobilisation) to another (for example soft tissue mobilisation), nine compared nerve mobilisation delivered as part of a multi-component intervention to another non-surgical intervention (for example splint or therapeutic ultrasound), and three compared a mobilisation intervention other than nerve mobilisation (for example yoga or chiropractic treatment) to another non-surgical intervention. The risk of bias of the included studies was low in some studies and unclear or high in other studies, with only three explicitly reporting that the allocation sequence was concealed, and four reporting blinding of participants. The studies were heterogeneous in terms of the interventions delivered, outcomes measured and timing of outcome assessment, therefore, we were unable to pool results across studies. Only four studies reported the primary outcome of interest, short-term overall improvement (any measure in which patients indicate the intensity of their complaints compared to baseline, for example, global rating of improvement, satisfaction with treatment, within three months post-treatment). However, of these, only three fully reported outcome data sufficient for inclusion in the review. One very low quality trial with 14 participants found that all participants receiving either neurodynamic mobilisation or carpal bone mobilisation and none in the no treatment group reported overall improvement (RR 15.00, 95% CI 1.02 to 220.92), though the precision of this effect estimate is very low. One low quality trial with 22 participants found that the chance of being 'satisfied' or 'very satisfied' with treatment was 24% higher for participants receiving instrument-assisted soft tissue mobilisation compared to standard soft tissue mobilisation (RR 1.24, 95% CI 0.89 to 1.75), though participants were not blinded and it was unclear if the allocation sequence was concealed. Another very low-quality trial with 26 participants found that more CTS-affected wrists receiving nerve gliding exercises plus splint plus activity modification had no pathologic finding on median and ulnar nerve distal sensory latency assessment at the end of treatment than wrists receiving splint plus activity modification alone (RR 1.26, 95% CI 0.69 to 2.30). However, a unit of analysis error occurred in this trial, as the correlation between wrists in participants with bilateral CTS was not accounted for. Only two studies measured adverse effects, so more data are required before any firm conclusions on the safety of exercise and mobilisation interventions can be made. In general, the results of secondary outcomes of the review (short- and long-term improvement in CTS symptoms, functional ability, health-related quality of life, neurophysiologic parameters, and the need for surgery) for most comparisons had 95% CIs which incorporated effects in either direction.

AUTHORS' CONCLUSIONS

There is limited and very low quality evidence of benefit for all of a diverse collection of exercise and mobilisation interventions for CTS. People with CTS who indicate a preference for exercise or mobilisation interventions should be informed of the limited evidence of effectiveness and safety of this intervention by their treatment provider. Until more high quality randomised controlled trials assessing the effectiveness and safety of various exercise and mobilisation interventions compared to other non-surgical interventions are undertaken, the decision to provide this type of non-surgical intervention to people with CTS should be based on the clinician's expertise in being able to deliver these treatments and patient's preferences.

Reliability and efficacy of the new massage technique on the treatment in the patients with carpal tunnel syndrome

We aimed to bring a more understandable and applicable technique to the literature instead of “massage therapy” in CTS. We compared our new technique with the splint wear, of which the efficacy in CTS has been proven with many studies. Eighty-four patients between 31 and 65 years of age were included in the study. The patients were divided into two equal groups. In the first group, splint and “Madenci” hand massage technique were applied, and in the second group only splint was applied. A splint was provided for all patients with tendon and nerve gliding exercises, and also when needed analgesic drugs were given. When the pretreatment and posttreatment parameters were compared via repetitive measurement analysis, it was found that PGA and MDPGA were significantly decreased in both groups (P = 0.001), whereas grip strength was significantly increased (P = 0.001). While no statistically significant difference was found between the groups regarding pretreatment values (P > 0.05), the posttreatment PGA, MDPGA, and grip strength scores were significantly improved in Group I compared to Group II (P < 0.05). To the best our knowledge, the present study is the first and largest study in the literature conducted on the massage technique that will contribute to the treatment of CTS. As this new massage technique is easy for self-application, cheap, and practical, every patient with CTS can apply the massage to him/herself easily.

Integrating the international classification of functioning, disability, and health model into massage therapy research, education, and practice

Without an increase in clearly defined and clinically significant outcomes research in massage therapy (MT), the practice is in jeopardy of remaining on the fringes of accepted and utilized therapeutic care. This reality will slow the integration of MT into routine preventive, rehabilitative, curative, and supportive care. The International Classification of Functioning, Disability, and Health (ICF) developed by the World Health Organization is a comprehensive model of functioning and disability that provides a universal taxonomy of human functioning that is recognized globally. Integration of the ICF model into MT research, education, and practice would provide a foundation for a common language, particularly in regard to examining outcomes of MT.Here, we review the dynamic and respected ICF model as it applies to massage research, outcomes dissemination, education, and practice, with these specific objectives:To describe the specific domains of the ICF modelTo apply the described ICF domains to current massage practice and researchTo discuss how integration of the ICF model enhances communication and translation among those within and to those outside the MT fieldThe ICF model is ideal for application to MT interests because it works outside the typical focus on pathology or a specific organ system. Instead, the ICF focuses on impairment or limitations in functioning associated with health conditions. The ICF also highlights and incorporates the complex interactions of environment and personal factors and the impact that those factors exert on the domains of body structure, activity, and participation. This interaction has unique implications for MT practitioners, researchers, and clients/patients. Furthermore, the ICF model provides a framework for classifying outcomes, which is a critical aspect of clinical research.

Central sensitization does not identify patients with carpal tunnel syndrome who are likely to achieve short-term success with physical therapy

The aim of the current study was to identify whether hyperexcitability of the central nervous system is a prognostic factor for individuals with carpal tunnel syndrome (CTS) likely to experience rapid and clinical self-reported improvement following a physical therapy program including soft tissue mobilization and nerve slider neurodynamic interventions. Women presenting with clinical and electrophysiological findings of CTS were involved in a prospective single-arm trial. Participants underwent a standardized examination and then a physical therapy session. The physical therapy sessions included both soft tissue mobilization directed at the anatomical sites of potential median nerve entrapment and a passive nerve slider neurodynamic technique targeted to the median nerve. Pressure pain thresholds (PPT) over the median, radial and ulnar nerves, C5-C6 zygapophyseal joint, carpal tunnel and tibialis anterior muscle were assessed bilaterally. Additionally, thermal detection and pain thresholds were measured over the carpal tunnel and thenar eminence bilaterally to evaluate central nervous system excitability. Subjects were classified as responders (having achieved a successful outcome) or non-responders based on self-perceived recovery. Variables were entered into a stepwise logistic regression model to determine the most accurate variables for determining prognosis. Data from 72 women were included in the analysis, of which 35 experienced a successful outcome (48.6%). Three variables including PPT over the C5-C6 joint affected side <137 kPa, HPT carpal tunnel affected side <39.6º and general health >66 points were identified. If 2 out of 3 variables were present (LR + 14.8), the likelihood of success increased from 48.6 to 93.3%. We identified 3 factors that may be associated with a rapid clinical response to both soft tissue mobilization and nerve slider neurodynamic techniques targeted to the median nerve in women presenting with CTS. Our results support that widespread central sensitization may not be present in women with CTS who are likely to achieve a successful outcome with physical therapy. Future studies are now necessary to validate these findings.

Biomechanics of the transverse carpal arch under carpal bone loading

BACKGROUND

Carpal tunnel release and conservative interventions are widely used in clinical therapies of carpal tunnel syndrome. The efficacy of these treatment and interventions mainly lies in the exploitation of the mechanical properties of carpal tunnel. This study investigated the structural mechanics of the transverse carpal arch using cadaveric hands.

METHODS

Paired force was applied to the insertion sites of the transverse carpal ligament at both the distal (hamate-trapezium) and proximal (pisiform-scaphoid) levels of the carpal tunnel. The two pairs of forces were simultaneously applied in an inward or outward direction when the transverse carpal ligament was intact and transected. Transverse carpal arch and carpal tunnel compliance in response to the forces were analyzed. Three-way repeated measures ANOVA were used to examine the effect of the transverse carpal ligament status (intact/transected), the level of the carpal tunnel (distal/proximal) and the force application direction (inward/outward) on the biomechanics of the transverse carpal arch.

FINDINGS

Transverse carpal ligament plays a stabilizing role in resisting outward deformation of the carpal tunnel. The carpal tunnel at the proximal level is more flexible than the carpal tunnel at the distal level. The carpal tunnel is more compliant under the inward force application than under the outward force application.

INTERPRETATION

The understanding of carpal tunnel mechanics potentially helps to improve the existing strategies and to develop alternatives for the treatment of carpal tunnel syndrome.

Carpal tunnel syndrome. Part I: effectiveness of nonsurgical treatments--a systematic review

OBJECTIVE

To review literature systematically concerning effectiveness of nonsurgical interventions for treating carpal tunnel syndrome (CTS).

DATA SOURCES

The Cochrane Library, PubMed, EMBASE, CINAHL, and PEDro were searched for relevant systematic reviews and randomized controlled trials (RCTs).

STUDY SELECTION

Two reviewers independently applied the inclusion criteria to select potential studies.

DATA EXTRACTION

Two reviewers independently extracted the data and assessed the methodologic quality.

DATA SYNTHESIS

A best-evidence synthesis was performed to summarize the results of the included studies. Two reviews and 20 RCTs were included. Strong and moderate evidence was found for the effectiveness of oral steroids, steroid injections, ultrasound, electromagnetic field therapy, nocturnal splinting, and the use of ergonomic keyboards compared with a standard keyboard, and traditional cupping versus heat pads in the short term. Also, moderate evidence was found for ultrasound in the midterm. With the exception of oral and steroid injections, no long-term results were reported for any of these treatments. No evidence was found for the effectiveness of oral steroids in long term. Moreover, although higher doses of steroid injections seem to be more effective in the midterm, the benefits of steroids injections were not maintained in the long term. For all other nonsurgical interventions studied, only limited or no evidence was found.

CONCLUSIONS

The reviewed evidence supports that a number of nonsurgical interventions benefit CTS in the short term, but there is sparse evidence on the midterm and long-term effectiveness of these interventions. Therefore, future studies should concentrate not only on short-term but also on midterm and long-term results.

A randomized sham-controlled trial of a neurodynamic technique in the treatment of carpal tunnel syndrome

STUDY DESIGN

Randomized, controlled trial.

OBJECTIVES

To assess the believability of a novel sham intervention for a neurodynamic technique (NDT) in participants with signs and symptoms of carpal tunnel syndrome (CTS). Additionally, we wished to assess a potential mechanism of NDT (hypoalgesia) and to compare outcomes related to clinical pain and upper extremity disability between NDT and a sham intervention.

BACKGROUND

Preliminary evidence suggests that NDT is effective in the treatment of CTS. A sham-controlled study is lacking from the literature and could provide insight to the efficacy of NDT, as well as the corresponding mechanisms.

METHODS

Participants with signs and symptoms consistent with CTS provided baseline measures of expectation, clinical pain intensity, upper extremity disability, and experimental pain sensitivity. Participants were then randomly assigned to receive either a NDT known to anatomically stress the median nerve or a sham technique intended to minimize stress to the median nerve. Following brief exposure to the assigned technique, expectation was reassessed to observe for group-dependent changes. Participants received the assigned intervention over 3 weeks. Additionally, all participants received a prefabricated wrist splint for their involved hands, with instructions to sleep in the splint and to wear it during painful activities when awake. Following 3 weeks of the assigned intervention and splint wear, baseline measures were reassessed and participants were asked which intervention they believed they had received.

RESULTS

Forty females agreed to participate. Expectations for pain relief and perceived group assignment were similar between the groups. Within-session decreases in clinical pain intensity and pressure pain sensitivity were observed independent of group assignment. Reduction of temporal summation was observed only in participants receiving NDT. Significant improvements in clinical pain intensity and upper extremity disability were observed at 3 weeks, independent of group assignment.

CONCLUSION

The sham intervention was successful in blinding the participants. Immediate changes in pain sensitivity and intensity and 3-week changes in clinical pain intensity and upper extremity disability associated with NDT were equivalent to a sham intervention to which the participants were adequately blinded. Conversely, reduction of temporal summation was only observed in participants receiving the NDT, suggesting the potential of a favorable neurophysiological effect.
