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

Effect of High-Intensity Laser Therapy on Carpal Tunnel Syndrome Patients: A Systematic Review and Meta-analysis

OBJECTIVE

To provide a strong foundation for the use of high-intensity laser therapy in carpel tunnel syndrome, we conducted a systematic review and meta-analysis to investigate the outcomes of short- and long-term follow-up studies.

DESIGN

This is a systematic review and meta-analysis.

RESULTS

Sample sizes of included studies ranged from 16 to 98 patients ( N = 308). Overall, a significant difference between the treatment and control groups were found across majority of the measures. Studies using a 4-wk follow-up period, however, only found significantly greater benefits for high-intensity laser therapy in visual analog scale compared with placebo ( P = 0.0191), transcutaneous electrical nerve stimulation ( P = 0.0026), and low-intensity laser therapy 20 J/cm 2 ( P < 0.0002), and exercise ( P < 0.0001). For improvement in visual analog scale score over a long treatment period, high-intensity laser therapy was also preferred over control group ( P < 0.0071). Insufficient evidence exists to determine effect of high-intensity laser therapy on nerve conduction examinations. The only statistically significant differences observed in examinations were in relation to sensory nerve action potential ( P = 0.0083) and sensory nerve conduction velocity ( P = 0.0468).

CONCLUSIONS

Moderate evidence exists regarding efficacy of high-intensity laser therapy compared with placebo, high-intensity laser therapy + wrist splint, and exercise in a short period of follow-up time but evidence on long-term follow-up is limited.

How Useful Is TikTok for Patients Searching for Carpal Tunnel Syndrome-Related Treatment Exercises?

Since orthopedic surgery has been slower to acknowledge the rise of social media for distributing medical information, this study aims to evaluate TikTok videos' quality and educational value in relation to carpal tunnel syndrome treatment exercises. TikTok was searched using the hashtags "#carpaltunnelexercises", "#carpaltunnelremedies", "#carpaltunnelrehab", and "#physicaltherapyforcarpaltunnel". The engagement indicators were documented and the video content quality was assessed using the DISCERN, CTEES, JAMA, and GQS grading scales. There were 101 videos included, which accumulated 20,985,730 views. The videos received 1,460,953 likes, 15,723 comments, 243,245 favorites, and 159,923 shares. Healthcare professionals were responsible for 72% of the video uploads, whereas general users contributed 28%. More healthcare professionals' videos were graded as "poor" (79%) compared to general users (21%). General users received slightly more video grades of "very poor" (52%) than healthcare professionals (48%). For the DISCERN grading, the videos by healthcare professionals were significantly better than those by general users in terms of reliability, achieving aims, and relevancy. They were also superior in the overall composition of the health information derived from the total DISCERN score. However, no significant differences were found between the two groups when using the CTEES, JAMA, and GQS grading scales. Overall, despite the emergence of TikTok as a medical information tool, the quality and educational value of the carpal tunnel syndrome exercise videos were poor.

Comparison of Effects of Ultrasound Therapy and Nerve-Gliding Techniques on Patients with Carpal Tunnel Syndrome: A Randomized Clinical Trial

Background

Carpal tunnel syndrome (CTS) is a common neuropathy caused by pressure on the median nerve in the wrist, affecting 1% to 5% of the population. Treatment options include pharmacologic management, rest, splints, local steroid injections, and physical therapy. Conservative treatments, such as ultrasound therapy and nerve-gliding exercises, can also be effective.

Objectives

This study aimed to compare the effects of ultrasound therapy and nerve-gliding exercises on reducing symptoms, improving hand function, and electrodiagnostic tests in patients with CTS.

Methods

This randomized clinical trial was conducted on patients with CTS at the specialized physical medicine and rehabilitation clinic at Birjand University of Medical Sciences. The study included 48 patients with CTS, divided into two groups. The ultrasound group received therapy at a frequency of 1 MHz and a current intensity of 1 watt/cm², with each session lasting 5 minutes. The nerve-gliding group underwent 10 sessions of treatment, three times a week. Pain intensity was evaluated using VAS criteria, symptom intensity using the BOSTON Questionnaire, and median nerve latency with EMG-NCS.

Results

The study included 48 patients with CTS, divided into two groups. Both groups showed improved severity of symptoms and function scores at the end of the study (P < 0.001). The ultrasound group significantly reduced the sensory and motor median nerve latency scores (P < 0.001 and P = 0.001, respectively), and the pain score diminished significantly in both groups (P < 0.001).

Conclusions

Ultrasound and neural-gliding techniques are effective in reducing patients' symptoms and pain intensity in the short term. Additionally, ultrasound can improve electrodiagnostic indicators.

Effects of Platelet-Rich Plasma Combined with Physical Therapy on IL-1β, TGF-β1, and MMP-3 in Patients with Knee Osteoarthritis

The occurrence of osteoarthritis in the knee joint is regulated by a complex network, and there is currently no specific therapeutic drug available. Functional exercises and treatments targeting inflammatory factors have shown the potential to alleviate knee osteoarthritis to some extent. Therefore, the aim of this study was to assess the intra-articular injection (IAI) of autologous platelet-rich plasma (PRP) combined with physical therapy (PT) in treating knee osteoarthritis. A total of 128 patients with knee osteoarthritis were included in the study, including 64 males and 64 females. A total of 128 patients were divided into sodium hyaluronate group (HA group), PRP group, PRP + PT group, and PT group, with 32 cases in each group. Visual analog scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Japanese Orthopaedic Association (JOA) were employed to evaluate the recovery of patients from pain and osteoarthritis. Color Doppler ultrasound imaging technology was utilized to assess joint effusion, synovial membrane thickness, and articular cartilage thickness in patients with knee osteoarthritis. Enzyme-linked immunosorbent assay (ELISA) was employed to detect the levels of interleukin-1β (IL-1β), transforming growth factor-β1 (TGF-β1), and matrix metallopeptidase 3 (MMP-3) in the synovial fluid. Compared to the HA group, the PT group, PRP group, and PRP combined with PT (PRP + PT) group all showed reduced VAS and WOMAC scores, increased JOA scores, decreased joint effusion, synovial membrane thickness, and articular cartilage thickness in the knee joint. Additionally, levels of IL-1β and MMP-3 in the synovial fluid decreased, while TGF-β1 levels increased (P < 0.05). Compared with the PT group, the VAS and WOMAC scores of the knee joint in the PRP group decreased, JOA scores increased, joint effusion, synovial thickness, and articular cartilage thickness decreased, but there was no statistically significant difference (P > 0.05), and the PRP + PT group showed decreased VAS and WOMAC scores, increased JOA scores, reduced joint effusion, synovial membrane thickness, and articular cartilage thickness in the knee joint. Moreover, levels of IL-1β and MMP-3 in the synovial fluid decreased, while TGF-β1 levels increased (P < 0.05). No severe adverse reactions were observed in any of the four groups, but the pain rate in the PRP + TP group was significantly lower than PT group, PRP group, and PRP + PT group (P < 0.05). The efficacy of intra-articular injection of PRP combined with exercise therapy in the treatment of knee osteoarthritis is superior to that of single interventions such as simple interventions of HA, PRP injection, and PT. Furthermore, intra-articular injection of PRP combined with exercise therapy demonstrates enhanced effectiveness in improving the inflammatory levels associated with knee osteoarthritis and facilitating the rehabilitation process.

The effectiveness of nerve mechanical interface treatment for entrapment neuropathies in the limbs: A systematic review with metanalysis

BACKGROUND

Neurodynamic approach employs neural mobilization and mechanical nerve interface techniques. While published studies investigated the efficacy of neural mobilization, it is currently unknown whether manual treatment of the nerve mechanical interface is effective in the treatment of people with entrapment neuropathies.

OBJECTIVES

Assess the effectiveness of mechanical interface treatment, including joint and soft tissue techniques, on pain and function in people with peripheral entrapment neuropathies.

DESIGN

Intervention systematic review with metanalysis.

METHODS

the databases MEDLINE, CINAHL, AMED, APA PsycINFO, SPORTDiscus, PubMed and ScienceDirect were searched from their inception to October 2022. Randomized controlled trials investigating mechanical interface treatment in isolation in patients with peripheral entrapment neuropathies were included. Two independent reviewers performed study selection, data extraction and risk of bias assessment using the Cochrane RoB 2.0 tool. Certainty of evidence for each outcome was judged using the GRADE framework.

RESULTS

11 studies were included in the review, all investigating carpal tunnel syndrome (CTS). Due to high heterogeneity of interventions and comparators, only five studies were pooled in a random-effects meta-analysis. There was evidence of mechanical interface techniques being more effective in reducing pain than sham (MD -2.47 [-3.94;-0.99]) and similarly effective as neural mobilization (MD -0.22 [-0.76; 0.33]) in CTS, albeit with low to very low certainty in the results.

CONCLUSION

mechanical interface techniques are effective for improving pain and function in people with CTS. However, the marked heterogeneity of included interventions and comparators prevents clinical recommendation of specific treatments.

Neuromodulation of the median nerve in carpal tunnel syndrome, a single-blind, randomized controlled study

Background

This study aimed to evaluate the efficacy of pulsed radiofrequency applied using transcutaneous electrodes in carpal tunnel syndrome (CTS).

Methods

After randomization, the patients received two cycles of noninvasive pulsed radiofrequency (NiPRF), once weekly, or splinting (the control group) for three months. Clinical evaluations were recorded at baseline and weeks 4 and 8. The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was used to determine the functional status and symptom severity.

Results

Sixty-two patients were followed up for three months. There was no difference between the groups in the BCTQ scores before and after treatment. The NiPRF group found a significant difference between the BCTQ measurements at all time intervals (paired sample t -test; P < 0.001). In the splint group, there was a significant difference only between the basal-1st month and basal-3rd month (paired samples t -test; P < 0.001). The main effect of the time variable was statistically significant (ANOVA; P < 0.001), but the group variable was not. There was no correlation between the BCTQ results measured at any time and the electroneuromyelogragphy findings in either group.

Conclusions

NiPRF effectively improves symptoms and functionality in patients with CTS for up to 3 months. Thus, NiPRF can be considered an easy, safe, and useful alternative treatment modality for CTS.

Local corticosteroid injection versus physical therapy for the treatment of carpal tunnel syndrome: A systematic review and meta-analysis of randomized controlled trials

The comparative effect of commonly used conservative treatments for carpal tunnel syndrome remained controversial. The purpose of this study was to compare the clinical effect of local corticosteroid injection and physical therapy for the treatment of carpal tunnel syndrome. A systematic literature search of PubMed, EMBASE, and Cochrane library was conducted to identify relevant randomized clinical trials published before 21st Mar 2023. Two independent reviewers assayed quality of included studies using the Cochrane collaboration risk of bias tool. Relevant data were extracted and pooled analyses were conducted. Outcome measurements included Boston Carpal Tunnel Syndrome Questionnaire, visual analogue scale and some electrophysiology tests, while the former two were set as the primary outcomes. Subgroup analysis and sensitive analysis were performed and publication bias was evaluated. Heterogeneity among the included studies was examined using the I2 statistic. After selection, 12 studies were identified eligibility for inclusion. Only one study was found to have a high risk of bias. Pooled data of primary outcomes did not show any differences between treatments, and subgroup analysis supported the results. However, patients treated with local corticosteroid injection showed better improvement in distal motor latency (p = 0.002) and compound muscle action potential (p = 0.04). Some studies failed to pass the sensitive analysis, indicating the related analysis might be not so stable. A slight publication bias was observed in subgroup analysis of function scales, among three publication bias test. In conclusion, compared to physical therapy, local corticosteroid injection might have better treatment effects on carpal tunnel syndrome.

Whole-Body Photobiomodulation Therapy for Fibromyalgia: A Feasibility Trial

Effective treatment for fibromyalgia (FM) is lacking and further treatment options are needed. Photobiomodulation therapy (PBMT) represents one potential treatment option. Whilst favourable findings have been reported using localised PBMT, no investigations have established the value of whole-body PBMT for the complete set of symptom domains in FM. A single-arm feasibility study was conducted in accordance with CONSORT (Consolidated Standards of Reporting Trials) guidelines. A non-probability sampling method was used to access individuals with FM. The primary outcome measure was identified as the Revised Fibromyalgia Impact Questionnaire (FIQR). Forty-nine participants were screened and twenty-one trial participants entered the trial. Nineteen participants completed the intervention (18 whole-body PBMT sessions over approximately six weeks). Descriptive statistics and qualitative analysis was undertaken to represent feasibility outcomes. Acceptability of the trial device and processes were established. Outcome measures towards efficacy data were guided by core and peripheral OMERACT (outcomes measures in rheumatological clinical trials) domains, utilising a combination of participant-reported and performance-based outcome measures. Data for the embedded qualitative component of the trial were captured by participant-reported experience measures and audio-recorded semi-structured interviews. Positive changes were observed for FM-specific quality of life, pain, tenderness, stiffness, fatigue, sleep disturbance, anxiety, depression and cognitive impairment. Patient global assessment revealed improvements at 6 weeks, with continued effect at 24 weeks. FM-specific quality of life at 24 weeks remained improved compared with baseline scores. The findings provided evidence to support a full-scale trial and showed promise regarding potential efficacy of this novel non-invasive treatment in an FM population.

The effectiveness of biophysical agents in the treatment of carpal tunnel syndrome- an umbrella review

BACKGROUND

Our objective was to summarize, synthesize, and integrate the evidence evaluating the effectiveness of biophysical agents compared to other conservative treatments, for the management of carpal tunnel syndrome (CTS).

METHODS

This was an overview of systematic reviews (SRs). We searched several online databases and obtained SRs relating to managing CTS using biophysical agents. Two independent researchers screened and appraised the quality of the SRs using the A MeaSurement Tool to Assess systematic Reviews-2 appraisal tool. We extracted information related to study characteristics as well as the effectiveness of biophysical agents for CTS, the effect sizes, and between-group significances. We categorized the information based on the type of biophysical agent. We also performed a citation mapping and calculated the corrected covered area index.

RESULTS

We found 17 SRs addressing 12 different biophysical agents. The quality of the SRs was mainly critically low (n = 16) or low (n = 1). The evidence was inconclusive for the effectiveness of Low-level Laser therapy and favorable for the short-term efficacy of non-thermal ultrasound in improving symptom severity, function, pain, global rating of improvement, satisfaction with treatment, and other electrophysiological measures compared to manual therapy or placebo. Evidence was inconclusive for Extracorporeal Shockwave therapy, and favorable for the short-term effectiveness of Shortwave and Microwave Diathermy on pain and hand function. The corrected covered area index was lower than 35% indicating a low overlap of the SRs.

CONCLUSIONS

The findings were based on low-quality primary studies, with an unclear or high risk of bias, small sample sizes, and short follow-ups. Therefore, no recommendations can be made for the long-term effectiveness of any biophysical agents. High-quality evidence is needed to support evidence-based recommendations on the use of biophysical agents in the management of CTS.

Carpal Tunnel Syndrome: Neuropathic Pain Associated or Not with a Nociplastic Condition

Carpal tunnel syndrome (CTS) has been traditionally classified as primarily a neuropathic condition with or without pain. Precision medicine refers to an evidence-based method of grouping patients based on their susceptibility to biology, prognosis of a particular disease, or in their response to a specific treatment, and tailoring specific treatments accordingly. In 2021, the International Association for the Study of Pain (IASP) proposed a grading system for classifying patients into nociceptive, neuropathic, or nociplastic phenotypes. This position paper presents data supporting the possibility of subgrouping individuals with specific CTS related-pain into nociceptive, neuropathic, nociplastic or mixed-type phenotypes. Carpal tunnel syndrome is a neuropathic condition but can also be comorbid with a nociplastic pain condition. The presence of extra-median symptoms and the development of facilitated pain processing seem to be signs suggesting that specific CTS cases can be classified as the nociplastic pain phenotype. The clinical responses of therapeutic approaches for the management of CTS are inconclusive. Accordingly, the ability to identify the predominant pain phenotype in patients with CTS could likely be problematic for producing efficient treatment outcomes. In fact, the presence of a nociplastic or mixed-type pain phenotype would explain the lack of clinical effect of treatment interventions targeting the carpal tunnel area selectively. We propose a clinical decision tree by using the 2021 IASP classification criteria for identifying the predominant pain phenotype in people with CTS-related pain, albeit CTS being a priori a neuropathic pain condition. The identification of a nociplastic-associated condition requires a more nuanced multimodal treatment approach to achieve better treatment outcomes.

A Pilot Study In to the Effects of Cervical Manual Therapy Plus Conventional Physical Therapy on Clinical Outcomes and Electrodiagnostic Findings in People With Carpal Tunnel Syndrome

Background

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy that has a significant impact on patients' quality of life. Current physical therapy treatment options show limited effects or low-quality evidence, especially in the long term. To date, there has been little research to look at the effects of treating the cervical spine on decreasing symptoms distally to the carpal tunnel. This study aimed to evaluate the effects of cervical manual therapy plus conventional physical therapy on patients with carpal tunnel syndrome.

Methods

This pilot pretest/posttest and six-month follow-up clinical study included 15 adult patients with CTS. For two weeks, each patient received 10 sessions of supervised intervention treatment. The efficacy of the therapies was assessed at baseline (T0), immediately after treatment (T1), and six months after treatment (T2). The visual analog scale (VAS), a symptom severity scale, the functional capacity scale of the Boston Carpal Tunnel Questionnaire (BCTQ), the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, median nerve motor distal latency (mMDL), and median sensory nerve conduction velocity (mSNCV) were outcome measures.

Results

There were significant improvements in all measures between the baseline values at T0 and those recorded immediately after the treatment at T1 or six months later at T2 (p<.05).

Conclusion

This pilot study indicates that cervical manual therapy plus conventional physical therapy applied for two weeks improves clinical outcomes and electrodiagnostic findings in people with CTS.

Use of Iontophoresis with Corticosteroid in Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis

BACKGROUND

Carpal tunnel syndrome is a neuropathy that affects the median nerve. The aim of this review is to synthesize the evidence and perform a meta-analysis on the effects of iontophoresis in people with carpal tunnel syndrome.

METHODS

The search was carried out using PubMed, Web of Science, Scopus, CINHAL Complete, Physiotherapy Evidence Database, and SciELO. The methodological quality was evaluated using PEDro. A standardized or mean difference meta-analysis (Hedge's g) using a random-effects model was calculated.

RESULTS

Seven randomized clinical trials using iontophoresis for electrophysiological, pain, and functional outcomes were included. The mean of PEDro was 7/10. No statistical differences were obtained for the median sensory nerve conduction velocity (SMD = -0.89; p = 0.27) or latency (SMD = -0.04; p = 0.81), motor nerve conduction velocity (SMD = -0.04; p = 0.88) or latency (SMD = -0.01; p = 0.78), pain intensity (MD = 0.34; p = 0.59), handgrip strength (MD = -0.97; p = 0.09), or pinch strength (SMD = -2.05; p = 0.06). Iontophoresis only seemed to be superior in sensory amplitude (SMD = 0.53; p = 0.01).

CONCLUSIONS

Iontophoresis did not obtain an enhanced improvement compared to other interventions, but no clear recommendations could be made due to the limited number of included studies and the heterogeneity found in the assessment and intervention protocols. Further research is needed to draw sound conclusions.

Clinical and electrophysiological efficacy of extracorporeal shock-wave therapy in carpal tunnel syndrome: a placebo-controlled, double-blind clinical trial

OBJECTIVE

The aim of this study was to evaluate the efficacy of radial extracorporeal shock wave therapy on pain, functionality, and electrophysiological measurements in carpal tunnel syndrome.

METHODS

Between June 2021 and January 2022, a total of 66 wrists in 45 participants with mild-to-moderate carpal tunnel syndrome were included in this double-blind, prospective, randomized, placebo-controlled study. Patients were randomized into two groups, namely, the radial extracorporeal shock wave therapy (group 1, n=33) and the sham radial extracorporeal shock wave therapy (group 2, n=33). Night splints and tendon nerve gliding exercises were given to all participants. The participants were evaluated at baseline and the first month after treatment. Participants were evaluated using a visual analog scale, the Boston Carpal Tunnel Questionnaire, Leeds Neuropathic Symptom and Symptom Assessment, and electrophysiological examinations.

RESULTS

A total of 37 participants (a total of 55 wrists, radial extracorporeal shock wave therapy n=27, and sham radial extracorporeal shock wave therapy n=28) completed the study. After the intervention, there was a significant decrease in visual analog scale values (p<0.001) and a significant increase in Boston Carpal Tunnel Questionnaire scores (p<0.001) and Leeds Neuropathic Symptom and Symptom Assessment scores (p<0.001). In electrophysiological measurements, there was a significant decrease in median nerve sensory (p=0.002) and motor (p=0.003) distal latency, and a significant increase in median nerve sensory conduction velocity (p=0.026) was found in the radial extracorporeal shock wave therapy group.

CONCLUSION

This study shows that radial extracorporeal shock wave therapy has positive effects on pain, functionality, and electrophysiological measurements for mild-to-moderate carpal tunnel syndrome 1 month after application.

Manual Therapy and Related Interventions for Carpal Tunnel Syndrome: A Systematic Review and Meta-Analysis

Objective: Systematic review and meta-analysis to assess the efficacy of Manual therapy and related interventions in the treatment of carpal tunnel syndrome (CTS) based on Boston carpal tunnel questionnaire. Design: Systematic review and meta-analysis. Subjects: Carpal tunnel syndrome. Interventions: Manual therapy and related interventions versus other therapies or manual therapy and related interventions plus other therapies versus other therapies. Outcomes measures: Boston carpal tunnel questionnaire. Results: A total of 6 studies were included, including 211 cases in the manual therapy group and 211 cases in the control group. The quality of the included articles was high, and the results of meta-analysis showed that manual therapy and related interventions were superior in terms of improving the Boston carpal tunnel questionnaire Symptom Severity score in patients with CTS (standardised mean difference [SMD] -1.13, 95% CI -1.40 to -0.87), were superior to control groups in terms of improving the Boston carpal tunnel questionnaire functional capacity scale in patients with CTS (SMD -1.01,95% CI -1.24 to -0.77). Conclusion: The results of this meta-analysis suggested that manual therapy and related interventions were better than control groups in treating CTS. Manual therapy and related interventions could relieve the symptoms of patients with CTS and promote the recovery of hand function. Manual therapy and related interventions should be considered clinically effective methods for treating CTS. Registration: The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO; No. CRD 42020201389). Contribution of the Article: Manual therapy and related interventions could relieve the symptoms of patients with CTS and promote the recovery of hand function. Manual therapy and related interventions should be considered clinically effective methods for treating CTS.

Use of Sonophoresis with Corticosteroids in Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis

Carpal tunnel syndrome is a neuropathic disease. It is one of the most frequent musculoskeletal pathologies affecting the upper limbs. One of most frequently used non-surgical treatments is corticosteorids. There are several alternatives for corticosteroids administration. One of them is phonophoresis, this being an effective and painless method of treatment. A systematic review and meta-analysis have been conducted over the use of phonophoresis with corticosteroids for the treatment of carpal tunnel syndrome compared to other non-surgical treatment methods. Keywords from Medical Subjects Headings (MeSH) were used in the following databases: Wos, Scopus, CINHAL, SciELO and PeDro. A total of 222 potentially relevant articles were retrieved. Eleven articles analysing the efficacy of phonophoresis with corticosteroids in reducing pain symptoms in individuals with carpal tunnel syndrome were included, 10 of which were used to conduct the meta-analysis. A conclusion could not be reached as to the application of phonophoresis with corticosteroids being better than other treatment methods, except for the perception of pain and an improved motor and sensory nerve conduction in cases of mild to moderate carpal tunnel syndrome.

Whole-body photobiomodulation therapy for chronic pain: a protocol for a feasibility trial

INTRODUCTION

Chronic pain conditions are a leading cause of disease and disability. They are associated with symptoms such as fatigue, sleep and mood disturbances. Minimal evidence is available to support effective treatments and alternatives treatment approaches are called for. Photobiomodulation therapy has been highlighted as one promising option. A whole-body therapy device (NovoTHOR) has recently been developed with a number of potential advantages for people with chronic pain. Research is needed to consider the feasibility of this device.

METHODS AND ANALYSIS

A single-centre single-armed (no placebo group) feasibility study with an embedded qualitative component will be conducted. The intervention will comprise 18 treatments over 6 weeks, with 6-month follow-up, in the whole-body photobiomodulation device. A non-probability sample of 20 adult participants with a clinician diagnosis of chronic axial pain, polyarthralgia, myofascial pain or widespread pain will be recruited (self-referral and clinician referral). Outcome measures will focus on acceptability of trial processes with a view to guiding a definitive randomised controlled trial. Analyses will use descriptive statistics for quantitative aspects. The qualitative element will be assessed by means of a participant-reported experience questionnaire postintervention and semistructured audio-recorded interviews at three stages; preintervention, midintervention and postintervention. The latter will be transcribed verbatim and a reflexive thematic analysis will be used to identify emerging themes. Exploratory outcomes (participant-reported and performance-based measures) will be analysed according to data distribution.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Leicester Central Research and Ethics Committee. Findings will be disseminated via local chronic pain groups, public register update, submission for presentation at scientific meetings and open-access peer-reviewed journals, and via academic social networks.

Effectiveness of therapeutic ultrasound for the treatment of carpal tunnel syndrome (the USTINCTS trial): study protocol for a three-arm, prospective, multicentre, randomised controlled trial

INTRODUCTION

There has no consensus on optimal management of carpal tunnel syndrome (CTS), the most common compression neuropathy. Conservative therapy is generally accepted as first-line intervention. Therapeutic ultrasound has been widely reported to be treatment beneficial in nerve regeneration and conduction, and further accelerate compression recovery. The purpose of this study is to investigate the effectiveness of therapeutic ultrasound for CTS treatment.

METHODS AND ANALYSIS

This study protocol entails a three-arm, prospective, multicentre, randomised controlled trial. 162 eligible adult participants diagnosed with mild to moderate CTS by using criteria developed from a consensus survey by the UK Primary Care Rheumatology Society will be assigned to either (1) therapeutic ultrasound, (2) night splint or (3) therapeutic ultrasound +night splint (combined) group. Primary outcome will be difference in Symptom Severity Scale of Boston Carpal Tunnel Questionnaire (BCTQ-SSS) at 6-week between night splint and therapeutic ultrasound +night splint groups. Secondary outcomes include Functional Status Scale of BCTQ, sleep questionnaire for interrupted sleep, EuroQol-5D for general health, Hospital Anxiety and Depression Scale for mental status, Work Limitations Questionnaire-25 for functional limitations at work, Global Rating of Change for treatment success and recurrence rate, physical examination, electrophysiological and ultrasound parameters. Intention-to-treat analyses will be used.

ETHICS AND DISSEMINATION

Ethics committees of all clinical centres have approved this study. The leading centre is Shanghai Sixth People's Hospital, whose approval number is 2021-152. New versions with appropriate amendments will be submitted to the committee for further approval. Final results will be published in peer-reviewed journals and presented at local, national and international conferences.

Clinical Value Analysis of High-Frequency Ultrasound Combined with Carpal Dorsiflexion Electrophysiological Detection in the Diagnosis of Early Carpal Tunnel Syndrome

Objective

To investigate the clinical value of ultrasound combined with electrophysiological examination in the diagnosis of early carpal tunnel syndrome, we aimed to provide a new EMG (electromyography) method for detecting early carpal tunnel syndrome by exploring the wrist back stretch position and electrophysiological examination.

Methods

For the 82-lateral wrist (case group) of 62 patients with clinical symptoms or confirmed carpal tunnel syndrome and 40 normal healthy patients, neuroelectrophysiological measurements were performed using a Keypoint6.0 EMG evoked potentiometer, measuring each group twice: conventional position (before compression) and dorsal wrist extension position. The measures for each measurement included DSL, DML, and CAMP. Measure sensory conduction first and then measure motor conduction. The measurements were analyzed in a comprehensive comparative analysis. Combined ultrasound examination, the positive rate of combined ultrasound examination and electrophysiological examination was compared, respectively.

Results

In the carpal tunnel syndrome (CTS) group, the anterior and posterior median nerve DSL was (4.27 ± 0.73) ms and (4.82 ± 0.65) ms, and SNAP was (13.32 ± 13.68) UV and (12.19 ± 11.04) UV; the median nerve (wrist-bunions) DML was (5.29 ± 1.26) ms and (5.54 ± 1.29) ms, and CMAP was (6.44 ± 2.40) mV and (6.21 ± 2.46) mV. Mid-median DSL and DM in the CTS group L were significantly longer than before compression; median nerve SNAP and CMAP were significantly reduced compared with before compression.

Conclusion

Electrophysiological testing at the dorsal carpal extension position has high diagnostic value in the diagnosis of mild carpal tunnel syndrome. It helps to improve the diagnostic rate of early carpal tunnel syndrome, while providing a more accurate and effective EMG detection of early carpal tunnel syndrome, and combination examination of neuroelectrophysiology and ultrasound can improve the diagnosis rate of compression peripheral nerve diseases and clarify the site, nature, and scope of compression lesions, which is worthy of clinical application.

Radiographs and Corticosteroid Injections at a New Patient Visit for Care of Carpal Tunnel Syndrome and Ulnar Neuropathy at the Elbow

Introduction  The benefit of radiographs or steroid injection for idiopathic carpal tunnel syndrome (CTS) or ulnar neuropathy at the elbow (UNE) is open to debate. We assessed: (1) Radiographs ordered and injections performed at a new patient visit for patients presenting with either idiopathic CTS or UNE; (2) The estimated payment reduction if we omit these interventions; and (3) Patient age, sex, geographic region, and work status associated with radiographs or injections at a new patient visit for patients presenting with either idiopathic CTS or UNE. Materials and Methods  Using a large database of commercial insurance claims, we identified patients with a new visit for either CTS ( N = 9,522), UNE ( N = 2,507), or both ( N = 962; 8.7%). We identified injections and radiographs, and estimated total payments for these interventions. We created three multivariable logistic regression models for each diagnosis to identify factors associated with the interventions. Results  Nearly one third of patients had radiographs at a new patient visit (30% and 32% for idiopathic CTS and UNE, respectively). Nearly 10% of patients with CTS and 2.6% with UNE received an injection. Both radiographs and injections representing annual minimum payments of over $345,000 and $294,000, respectively. Among people with CTS, radiographs were independently more common in the South and less common in the West. Injection for CTS was associated with younger age; North, Central, and South regions; and retired employment status. For people with UNE, radiographs were independently associated with younger age; South or West region; and retired or working employment status. Injection for UNE was associated with retired employment status. Conclusion  The prevalence of radiographs and injections suggests opportunities for savings, which might benefit clinicians with bundled or capitated payments and patients with large copayments or deductibles. The observed variation may reflect debate about whether these interventions are worthwhile. Level of Evidence  Diagnostic; Retrospective Database Level III study.

Ultrasound improves motor distal latency on patients with carpal tunnel syndrome: systematic review and meta-analysis

INTRODUCTION

Is the application of ultrasound effective on pain, the severity of the symptoms, physical function, strength, and neurophysiological parameters of the median nerve conduction in patients with carpal tunnel syndrome?

EVIDENCE ACQUISITION

A systematic review and meta-analysis of randomized controlled trials was performed by using a structured search strategy in Scopus, CINAHL, Web of Science and PEDro databases. All the primary studies included samples with carpal tunnel syndrome treated by: ultrasound versus no treatment, therapeutic ultrasound versus sham ultrasound, ultrasound and usual care versus usual care, or ultrasound and other intervention versus the same intervention. The outcomes measures registered were pain, severity of symptoms, function, strength, and neurophysiological parameters (motor distal latency and sensory distal latency) of the median nerve. Methodological quality was evaluated by PEdro Scale.

EVIDENCE SYNTHESIS

Ten clinical trials met the inclusion criteria for the systematic review. Eight trials were meta-analyzed, which included a total of 2069 patients with carpal tunnel syndrome. The methodological quality of the included studies ranged among limited (5 trials), moderate (3 trials), and high (2 trials). In one of the electrophysiological parameters (motor distal latency), a significant difference between groups after the use of ultrasound was observed (MD=-0.10; fixed 95% CI=-0.20, -0.01; P=0.04). No significant differences between groups were observed at post-treatment for pain (P=0.29), severity of symptoms (P=0.99), function (P=0.54), strength (P=0.27) and for the rest of the electrophysiological parameters evaluated (P>0.05).

CONCLUSIONS

The use of ultrasound on patients with carpal tunnel syndrome seems to improve motor distal latency. This finding implies a partial improvement at the neurophysiological level, representing a reduction in the grade of clinical severity. Additional clinical trials with a high methodological quality are needed to investigate the doses at which ultrasound are most effective.

Physical therapy versus radial extracorporeal shock wave therapy in the treatment of carpal tunnel syndrome: A randomized-controlled study

Objectives: This study aims to compare the efficacy of physical therapy (PT) and radial extracorporeal shock wave therapy (rESWT) in the treatment of carpal tunnel syndrome (CTS).

Patients and methods: Between May 2020 and July 2020, a total of 125 wrists of 95 patients (22 males, 73 females; mean age: 54.3±11.3 years; range, 19 to 69 years) with mild-to-moderate CTS were allocated into three groups and evaluated. The control group (Group 1, n=42) was treated with splinting and an exercise program. Group 2 (n=42) was treated with a total of three sessions of rESWT, splinting and an exercise program. Group 3 (n=41) was treated with a total of 15 sessions of PT modalities, splinting, and an exercise program. Each patient was evaluated before, three weeks and 12 weeks after treatment using a Visual Analog Scale (VAS), the Boston Carpal Tunnel Questionnaire (BCTQ), the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale, and electrodiagnostic testing.

Results: The reduction in VAS, BCTQ, LANSS, and improvement in sensory nerve conduction velocity were significantly greater at three and 12 weeks of follow-up in Groups 2 and 3, compared to Group 1 (p<0.001). A greater improvement was observed in all clinical parameters in Group 2, compared to Group 3 (p<0.001).

Conclusion: This is the first study to compare the treatment outcomes of PT and rESWT in the treatment of CTS. The results of this study show that both PT and rESWT are effective in the treatment of CTS; however, rESWT yields superior treatment effects compared to conventional PT. The practicalities of administering rESWT and its efficacy in the treatment of CTS may make it the treatment of choice.

Diagnostic modalities and physical therapy in patients with Carpal tunnel syndrome

Carpal tunnel syndrome (CTS) represents one of the most common compressive peripheral neuropathies on the upper extremities, and is characterized by compression of the medial nerve on its way through the carpal tunnel area. The first changes experienced by patients with CTS are sensory and occur mainly at night, and if they are not recognized and treated in time, they progress and become continuously present. Prolonged compression of the medial nerve in the region of the carpal tunnel can lead to permanent damage to this nerve, which can result in the patient losing the ability to distinguish between hot and cold, as well as atrophy of the thenar muscles and difficulty in palmar abduction of the thumb. The diagnosis of CTS is generally made based on the patient's symptoms, clinical history and anamnesis, as well as electrodiagnostic tests. In addition to these methods, provocative tests, nuclear magnetic resonance (NMR) and ultrasound examinations are used in the evaluation of CTS. In patients with CTS, a large number of treatment methods, both surgical and non-surgical, are used in clinical practice. Myofascial massage, ultrasound, interference currents, continuous short-wave diathermy, extracorporeal shock wave therapy (ESWT) have been shown to be beneficial in reducing pain and symptoms or improving function in patients with CTS in the short and medium term. It was also pointed out that there are no firm conclusions about optimal doses and therapeutic parameters. A better understanding of the etiology and pathophysiological mechanisms of CTS, as well as the effects of certain therapeutic modalities in the treatment of this condition, will contribute to further understanding of the origin and progression of CTS, as well as the possibilities of prevention and treatment of these patients in order to improve the quality of their life and the functionality of the affected limb.

Quality analysis of prior systematic reviews of carpal tunnel syndrome: an overview of the literature

BACKGROUND

Carpal tunnel syndrome (CTS) is a common condition greatly affects patients' quality of life and ability to work. Systematic reviews provide useful information for treatment and health decisions.

OBJECTIVE

This study aimed to assess the methodological quality of previously published systematic reviews on the treatment of CTS.

DESIGN AND SETTING

Overview of systematic reviews conducted at the Brazilian public higher education institution, São Paulo, Brazil.

METHODS

We searched the MEDLINE and Cochrane Library database for systematic reviews investigating the treatment of CTS in adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and measurement tool to assess systematic reviews (AMSTAR) were applied by two independent examiners.

RESULTS

Fifty-five studies were included. Considering the stratification within the AMSTAR measurement tool, we found that more than 76% of the analyzed studies were "low" or "very low". PRISMA scores were higher when meta-analysis was present (15.61 versus 10.40; P = 0.008), while AMSTAR scores were higher when studies performed meta-analysis (8.43 versus 5.59; P = 0.009) or when they included randomized controlled trials (7.95 versus 6.06; P = 0.043). The intra-observer correlation demonstrated perfect agreement (> 0.8), a Spearman's correlation coefficient of 0.829, and an ICC of0.857. The inter-observer correlation indicated that AMSTAR was more reliable than PRISMA.

CONCLUSION

Overall, systematic reviews of the treatment of CTS are of poor quality. Reviews with better-quality conducted meta-analysis and included randomized controlled trials. AMSTAR is a better tool than PRISMA because it has a better performance and should be recommended in future studies.

The long-term effect of neurodynamics vs exercise therapy on pain and function in people with carpal tunnel syndrome: A randomized parallel-group clinical trial

INTRODUCTION

Carpal tunnel syndrome (CTS) is a common disorder that limits function and quality of life. Little evidence is available on the long-term effect of neurodynamics and exercise therapy.

PURPOSE OF THE STUDY

This study aimed to examine the long-term effect of neurodynamic techniques vs exercise therapy in managing patients with CTS.

STUDY DESIGN

Parallel group randomized clinical trial.

METHODS

Of 57 patients screened, 51 were randomly assigned to either receiving four sessions of neurodynamics and exercise or home exercise therapy alone as a control. Blinded assessment was performed before treatment allocation, at treatment completion, and 6 months posttreatment. Outcome measures included Symptom Severity Scale (SSS), Functional Status Scale (FSS), Shortened version of the Disabilities of the Arm, Shoulder, and Hand (DASH), Numerical Pain Rating Scale, grip strength and range of motion.

RESULTS

Data from 41 individuals (52 hands) were analyzed. The neurodynamics group demonstrated significant improvement in all outcome measures at 1 and 6 months (P < .05). Mean difference in SSS was 1.4 (95% CI= 0.9-1.4) at 1 month and 1.6 (95% CI = 0.9-2.2) at 6 months. Mean difference in FSS was 0.9 (95% CI = 0.4-1.4) at 1 month and 1.4 (95% CI = 0.7-2.0) at 6 months. Significant between-group differences were found in pain score at 1 month (-1.93) and in FSS (-0.5) and Shortened version of DASH (-12.6) at 6 months (P < .05). No patient needed surgery 1 year after treatment.

CONCLUSIONS

Although both treatments led to positive outcomes, neurodynamics therapy was superior in improving function and strength and in decreasing pain.

Short-term Effects of Neurodynamic Techniques for Treating Carpal Tunnel Syndrome: A Systematic Review With Meta-analysis

OBJECTIVES

We aimed (1) to estimate the short-term effect (postintervention period) of neurodynamic techniques on pain, symptom severity, functional status, electrophysiological status, grip strength, and pinch strength in people with carpal tunnel syndrome (CTS); and (2) to estimate the effect of neurodynamic techniques compared to other physical therapy modalities and surgical interventions.

DESIGN

Intervention systematic review with meta-analysis.

LITERATURE SEARCH

We searched the MEDLINE, Cochrane Database of Systematic Reviews, Web of Science, Physiotherapy Evidence Database, and Scopus databases from their inception to September 2020.

STUDY SELECTION CRITERIA

We included randomized controlled trials reporting the effect of neurodynamic techniques on pain, symptom severity, function, distal motor latency, grip strength, and pinch strength in people with CTS.

DATA SYNTHESIS

Using the DerSimonian-Laird method, we estimated pooled standardized mean differences (SMDs) and 95% confidence intervals (CIs). We used the Grading of Recommendations Assessment, Development and Evaluation approach to judge the certainty of the evidence of each pairwise comparison.

RESULTS

There were 22 trials included (n = 1203 people with CTS; mean age, 26.0 to 57.9 years; mean symptom duration, 4.1 to 62.8 months). There was very low-certainty evidence of neurodynamic techniques improving pain (SMD, -0.54; 95% CI: -0.95, -0.13) and function (SMD, -0.35; 95% CI: -0.61, -0.09). There was no significant effect on symptom severity (very low certainty), distal motor latency (very low certainty), and grip and pinch strength (low certainty).

CONCLUSION

Neurodynamic techniques were effective for improving pain and function in people with CTS, albeit with very low-certainty evidence. J Orthop Sports Phys Ther 2021;51(12):566-580. Epub 16 Nov 2021.doi:10.2519/jospt.2021.10533.

Does TENS Reduce the Intensity of Acute and Chronic Pain? A Comprehensive Appraisal of the Characteristics and Outcomes of 169 Reviews and 49 Meta-Analyses

Background and Objectives: Uncertainty about the clinical efficacy of transcutaneous electric nerve stimulation (TENS) to alleviate pain spans half a century. There has been no attempt to synthesise the entire body of systematic review evidence. The aim of this comprehensive review was to critically appraise the characteristics and outcomes of systematic reviews evaluating the clinical efficacy of TENS for any type of acute and chronic pain in adults. Materials and Methods: We searched electronic databases for full reports of systematic reviews of studies, overviews of systematic reviews, and hybrid reviews that evaluated the efficacy of TENS for any type of clinical pain in adults. We screened reports against eligibility criteria and extracted data related to the characteristics and outcomes of the review, including effect size estimates. We conducted a descriptive analysis of extracted data. Results: We included 169 reviews consisting of eight overviews, seven hybrid reviews and 154 systematic reviews with 49 meta-analyses. A tally of authors' conclusions found a tendency toward benefits from TENS in 69/169 reviews, no benefits in 13/169 reviews, and inconclusive evidence in 87/169 reviews. Only three meta-analyses pooled sufficient data to have confidence in the effect size estimate (i.e., pooled analysis of >500 events). Lower pain intensity was found during TENS compared with control for chronic musculoskeletal pain and labour pain, and lower analgesic consumption was found post-surgery during TENS. The appraisal revealed repeated shortcomings in RCTs that have hindered confident judgements about efficacy, resulting in stagnation of evidence. Conclusions: Our appraisal reveals examples of meta-analyses with 'sufficient data' demonstrating benefit. There were no examples of meta-analyses with 'sufficient data' demonstrating no benefit. Therefore, we recommend that TENS should be considered as a treatment option. The considerable quantity of reviews with 'insufficient data' and meaningless findings have clouded the issue of efficacy. We offer solutions to these issues going forward.

Practice patterns in the conservative treatment of carpal tunnel syndrome: Survey results from members of the American Society of Hand Therapy

STUDY DESIGN

A cross-sectional descriptive design was used.

INTRODUCTION

Carpal tunnel syndrome (CTS) is a complex combination of symptoms resulting from compression of the median nerve within the carpal tunnel. A study that compares the conservative interventions identified in the literature with the actual conservative interventions being implemented by therapists for the treatment of CTS is not presently available.

PURPOSE OF THE STUDY

The purpose of this study was to examine conservative interventions for CTS as reported by certified hand therapists (CHTs) within various clinical settings. The study also aimed to identify the decision-making process for the selection of CTS interventions.

METHOD

CHT members of the American Society of Hand Therapists were surveyed electronically to obtain quantitative data.

RESULTS

Patient education, nocturnal orthosis, and ergonomic modifications ranked among the top conservative interventions utilized for CTS, whereas treatments such as magnet therapy, C-TRAC, and heating lamps ranked among the least utilized interventions. When selecting interventions, clinical expertise, research evidence, and patient preferences were all highly valued considerations for CHT.

DISCUSSION

Our study offers a unique summary of CHT practice patterns for CTS interventions and the associated decision-making processes. It compares findings with existing literature on this topic, offering researchers and clinicians a glimpse of the CTS practice trends.

CONCLUSION

This study may serve to prioritize future research studies based on the prevalence of intervention usage among the experts. It also serves as a guide to those seeking to understand the most common interventions utilized for conservative CTS treatment.

Resolving Long-Standing Uncertainty about the Clinical Efficacy of Transcutaneous Electrical Nerve Stimulation (TENS) to Relieve Pain: A Comprehensive Review of Factors Influencing Outcome

Pain is managed using a biopsychosocial approach and pharmacological and non-pharmacological treatments. Transcutaneous electrical nerve stimulation (TENS) is a technique whereby pulsed electrical currents are administered through the intact surface of the skin with the intention of alleviating pain, akin to 'electrically rubbing pain away'. Despite over 50 years of published research, uncertainty about the clinical efficacy of TENS remains. The purpose of this comprehensive review is to critically appraise clinical research on TENS to inform future strategies to resolve the 'efficacy-impasse'. The principles and practices of TENS are described to provide context for readers unfamiliar with TENS treatment. The findings of systematic reviews evaluating TENS are described from a historical perspective to provide context for a critical evaluation of factors influencing the outcomes of randomized controlled trials (RCTs); including sample populations, outcome measures, TENS techniques, and comparator interventions. Three possibilities are offered to resolve the impasse. Firstly, to conduct large multi-centered RCTs using an enriched enrolment with randomized withdrawal design, that incorporates a 'run-in phase' to screen for potential TENS responders and to optimise TENS treatment according to individual need. Secondly, to meta-analyze published RCT data, irrespective of type of pain, to determine whether TENS reduces the intensity of pain during stimulation, and to include a detailed assessment of levels of certainty and precision. Thirdly, to concede that it may be impossible to determine efficacy due to insurmountable methodological, logistical and financial challenges. The consequences to clinicians, policy makers and funders of this third scenario are discussed. I argue that patients will continue to use TENS irrespective of the views of clinicians, policy makers, funders or guideline panel recommendations, because TENS is readily available without prescription; TENS generates a pleasant sensory experience that is similar to easing pain using warming and cooling techniques; and technological developments such as smart wearable TENS devices will improve usability in the future. Thus, research is needed on how best to integrate TENS into existing pain management strategies by analyzing data of TENS usage by expert-patients in real-world settings.

Effectiveness of electrophysical modalities in the sensorimotor rehabilitation of radial, ulnar, and median neuropathies: A meta-analysis

INTRODUCTION

People with ulnar, radial or median nerve injuries can present significant impairment of their sensory and motor functions. The prescribed treatment for these conditions often includes electrophysical therapies, whose effectiveness in improving symptoms and function is a source of debate. Therefore, this systematic review aims to provide an integrative overview of the efficacy of these modalities in sensorimotor rehabilitation compared to placebo, manual therapy, or between them.

METHODS

We conducted a systematic review according to PRISMA guidelines. We perform a literature review in the following databases: Biomed Central, Ebscohost, Lilacs, Ovid, PEDro, Sage, Scopus, Science Direct, Semantic Scholar, Taylor & Francis, and Web of Science, for the period 1980-2020. We include studies that discussed the sensorimotor rehabilitation of people with non-degenerative ulnar, radial, or median nerve injury. We assessed the quality of the included studies using the Risk of Bias Tool described in the Cochrane Handbook of Systematic Reviews of Interventions and the risk of bias across studies with the GRADE approach described in the GRADE Handbook.

RESULTS

Thirty-eight studies were included in the systematic review and 34 in the meta-analysis. The overall quality of evidence was rated as low or very low according to GRADE criteria. Low-level laser therapy and ultrasound showed favourable results in improving symptom severity and functional status compared to manual therapy. In addition, the low level laser showed improvements in pinch strength compared to placebo and pain (VAS) compared to manual therapy. Splints showed superior results to electrophysical modalities. The clinical significance of the results was assessed by effect size estimation and comparison with the minimum clinically important difference (MCID).

CONCLUSIONS

We found favourable results in pain relief, improvement of symptoms, functional status, and neurophysiological parameters for some electrophysical modalities, mainly when applied with a splint. Our results coincide with those obtained in some meta-analyses. However, none of these can be considered clinically significant.

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

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

The Utilization of Joint Mobilization As Part of a Comprehensive Program to Manage Carpal Tunnel Syndrome: A Systematic Review

OBJECTIVE

The purpose of this review is to identify the role of joint mobilization for individuals with Carpal tunnel syndrome (CTS).

METHODS

A systematic search of 5 electronic databases (PubMed, CINAHL, Scopus, Cochrane Central Register of Controlled Trials, and SPORTDiscus) was performed to identify eligible full-text randomized clinical trials related to the clinical question. Joint mobilization had to be included in one arm of the randomized clinical trials to be included. Two reviewers independently participated in each step of the screening process. A blinded third reviewer assisted in cases of discrepancy. The PEDro scale was used to assess quality.

RESULTS

Ten articles were included after screening 2068 titles. In each article where joint mobilization was used, positive effects in pain, function, or additional outcomes were noted. In most cases, the intervention group integrating joint mobilization performed better than the comparison group not receiving joint techniques.

CONCLUSION

In the articles reviewed, joint mobilization was associated with positive clinical effects for persons with CTS. No studies used joint mobilization in isolation; therefore, results must be interpreted cautiously. This review indicates that joint mobilization might be a useful adjunctive intervention in the management of CTS.

Non-Surgical Management and Post-Surgical Rehabilitation of Carpal Tunnel Syndrome: An Algorithmic Approach and Practical Guideline

: One of the most common forms of entrapment neuropathy is Carpal Tunnel Syndrome (CTS). There are various treatment options for CTS. However, there are no clear and structured guidelines. This review classified the existing treatments and developed an algorithm to help physicians to choose the best option for their patients. Treatment options were summarized in three sections: non-surgical management of CTS, post-operative management of CTS, and practical open carpal tunnel release post-op protocol. The physicians can prescribe multiple treatment options to CTS patients. Corticosteroid in oral or injectable form has strong evidence in pain control and functional improvement in the short term. Shockwave therapy and nocturnal wrist splints display moderate therapeutic effects. Post carpal tunnel release rehabilitation can be started a few days after the operation.

A randomized comparative trial of corticosteroid phonophoresis, local corticosteroid injection, and low-level laser in the treatment of carpal tunnel syndrome

Background and aims

Carpal tunnel syndrome is the most prevalent peripheral neuropathy and has a considerable burden on health services. We tried to compare the therapeutic effects of local corticosteroid injection, low-level laser, and corticosteroid phonophoresis in the treatment of carpal tunnel syndrome.

Subjects and methods

We performed a randomized clinical trial with three parallel groups. The study was carried out at a University Hospital. In total, 42 participants including 31(73.8%) women were randomly allocated to the treatment groups with equal sizes. We assessed pain, symptom severity and functional status with Boston Carpal Tunnel Questionnaire, and performed median nerve conduction velocity studies. Evaluations were done before the interventions and in the fourth week of study. For the group corticosteroid, under the guidance of sonography, methylprednisolone with lidocaine was injected into the carpal tunnel. For laser therapy, we administered 10 sessions, each lasting 10 seconds. We used topical hydrocortisone acetate gel 10% as the anti-inflammatory agent with phonophoresis, 3 times per week for 10 sessions.

Results

Within-group analyses with paired t-test showed that local corticosteroid, laser, and phonophoresis are all effective treatments. Between-group analyses with ANOVA indicated that there were significant differences among the groups after four weeks in terms of pain (p = 0.004), in favor of corticosteroid; and in sensory delay (p = 0.001), in favor of laser. For the Boston Carpal Tunnel Questionnaire and median nerve motor latency, the results were not significant. There was no important side-effect after four weeks of follow-up.

Conclusion

The three treatments are comparable and beneficial for carpal tunnel syndrome.

The usage of multidisciplinary physical therapies at the Rio de Janeiro 2016 Olympic Summer Games: an observational study

BACKGROUND

This observational research study analyses the uptake of physical therapies treatments in the Polyclinic during the Rio 2016 Olympic Games.

OBJECTIVE

To describe the usage of physical therapies services - physical therapy, osteopath, chiropractic, and sports massage - by athletes and non-athletes and across different sports.

METHODS

The multidisciplinary team of physical therapies recorded treatment modalities, information on provider discipline and reason for attendance, in an Electronic Medical Record system throughout the 32 days of operation of the Olympic Polyclinic. Cold-therapy total immersion ice baths (TIIB) were provided as part of the services, but were reported and analysed separately.

RESULTS

There were 4993 encounters (4038 athletes, 955 non-athlete encounters). 1395 athletes (12.4% of all athletes) and 393 non-athletes sought treatment. For all four provider disciplines, in addition to TIIB, the primary reason for athlete attendance was for recovery (52% of all encounters), followed by injury treatment (30%), and maintenance (16%). Athletes reported "injury" as the main reason for physical therapy (92% of all encounters, 2.8 encounters per athlete), chiropractic (94%, 1.9) and osteopathy (91%, 1.8) visits. Almost all TIIB visits were used for recovery (98% of all TIIB encounters; 2.1 encounters per athlete). Athletes from handball (37% of all handball athletes), followed by judo (22%), and athletics (21%), presented the largest user groups.

CONCLUSION

This Olympic Polyclinic study evaluates the physical therapies' activity, and athlete's reason for use of the multidisciplinary physical therapies team, including total immersion ice bath provision. These results emphasise the importance of a multidisciplinary approach.

Physical and Occupational Therapy Use and Cost After Common Hand Procedures

PURPOSE

The use of routine physical therapy (PT) and occupational therapy (OT) after certain hand procedures, such as carpal tunnel release, remains controversial. The objective of this study was to evaluate baseline use, the change in use, variation in prescribing patterns by region, and costs for PT/OT after common hand procedures.

METHODS

Outpatient administrative claims data from patients who underwent procedures for carpal tunnel syndrome, trigger finger, carpometacarpal arthritis, de Quervain tenosynovitis, wrist ganglion cyst, and distal radius fracture were abstracted from the Truven Health MarketScan database from 2007 to 2015. The incidence of therapy and total reimbursement of therapy per patient were collected for each procedure over a 90-day postoperative observational period. Trends in use of therapy over time were described with average compound annual growth rates (CAGRs), a way of quantifying average growth over a specified observation period. Variations in the incidence of PT/OT use across 4 census regions were assessed.

RESULTS

The incidence of 90-day utilization of PT and OT after hand procedures was 14.0% and increased for all procedures during the observation period with an average CAGR of 8.3%. Cost per therapy visit was relatively stable when adjusted for inflation, with an average CAGR of 0.63%. Patients in the northeast had a significantly higher incidence of PT/OT use than those in the south and west for all procedures except carpometacarpal arthritis.

CONCLUSIONS

Use of PT and OT has increased over time after common hand procedures. Geographical variation in the utilization rate of these services is substantial. Limiting unwarranted variation of care is a health policy strategy for increasing value of care.

Incidence of referred carpal tunnel syndrome and carpal tunnel release surgery in the general population: Increase over time and regional variations

PURPOSE

To investigate the change in incidence of referred carpal tunnel syndrome (CTS) and carpal tunnel release (CTR) surgery over time and regional variations.

METHODS

From the nationwide patient registry, we identified all adult individuals who had received first-time CTS diagnosis (International Classification of Diseases, 10th Revision code G560) at secondary or tertiary level and first-time CTR surgery during the period of 9 years.

RESULTS

From 2001 through 2009, the incidence (per 100,000 person-years) of CTS diagnosed at secondary or tertiary level increased from 216 to 243 in women and from 95 to 119 in men and of CTR from 117 to 168 in women and from 52 to 78 in men. The mean annual increase in first-time CTR (95% confidence interval) was 5.1% (4.7-5.4) in women and 6.2% (5.6-6.7) in men. The age-standardized 3-year (2007-2009) incidence varied significantly across Sweden's 21 counties; compared to the county with the lowest incidence of CTR, the incidence rates in the other counties were higher by 6-152% (mean 60%) in women and by 20-182% (mean 85%) in men. The proportion of CTS-diagnosed individuals treated with surgery varied across counties from 53% to 81% in women and from 51% to 77% in men.

CONCLUSION

The incidence of referred CTS and of CTR surgery increased over time in both sexes, with large regional variations found in the incidence rates and in the proportion of individuals treated with surgery.

Treatment of carpal tunnel syndrome with wrist splinting: study protocol for a randomized placebo-controlled trial

Background

Carpal tunnel syndrome (CTS) is a common cause of pain, weakness, sensory loss, and activity limitations. Currently, the most common initial treatment is use of a rigid splint immobilizing the wrist, usually during night-time, for several weeks. Evidence regarding the efficacy and effect durability of wrist splinting is weak. The treatment is associated with costs and may cause discomfort and limit daily and work activities. No placebo-controlled trials have been performed.

Methods

This is a randomized controlled trial designed to assess the efficacy of a rigid wrist splint compared with soft wrist bandage (placebo) in patients with primary idiopathic CTS. The trial will be conducted at an orthopedic department. Patients, 25 to 65 years old, who seek primary health-care with symptoms of CTS will be screened, and potentially eligible patients will be referred to the study center. Patients who fulfill the trial’s eligibility criteria will be invited to participate. A total of 112 patients who provide informed consent will be randomly assigned to treatment with either a rigid wrist splint or a soft bandage to be used initially for 6 weeks at night and, if possible, during the day. The splints and bandages will be fitted with a temperature-monitoring device to measure the total time during which they have actually been worn. The trial participants will complete a questionnaire that includes the 6-item CTS symptoms scale (CTS-6); the 11-item disabilities of the arm, shoulder, and hand (QuickDASH) scale; and the EuroQol 5-dimension (EQ-5D) health status and quality-of-life measure at baseline and at 6, 12, 24, and 52 weeks after treatment start. The participants will undergo physical examination and nerve conduction testing at baseline and at 52 weeks. The trial’s primary outcomes are the change in the CTS-6 score from baseline to 12 weeks and the rate of carpal tunnel release surgery at 52 weeks.

Discussion

This is the first placebo-controlled randomized trial with electronic monitoring of actual splint use and will provide evidence regarding the efficacy of wrist splinting in patients with CTS.

Ultrasound therapy adds no benefit to splinting in carpal tunnel syndrome

INTRODUCTION

Therapeutic ultrasound has been suggested as a treatment for carpal tunnel syndrome (CTS), but existing trial evidence is of poor quality and inconclusive.

METHODS

We conducted a randomized, controlled trial of therapeutic ultrasound in mild to moderate CTS. Forty patients were treated with wrist splints plus either real or sham therapeutic ultrasound and followed for 1 year posttreatment. The primary outcome was change in symptom severity scale score. Secondary outcomes were functional status scale score, nerve conduction studies, and ultrasound imaging of the median nerve.

RESULTS

Both groups showed significant clinical and neurophysiological improvement at 6 and 12 months compared with baseline. There were no significant differences between groups at any time. In a multivariate analysis, the only independently significant predictors of the primary outcome were pretreatment symptom severity and additional treatments during follow-up.

DISCUSSION

We found no clinically significant benefit from ultrasound treatment for CTS.
