Efficacy of Manipulative Treatment for Carpal Tunnel Syndrome

Study Overview
=================
Brief Summary
-----------------
Hypothesis: Manipulative treatment can relieve patients of discomfort and dysfunction and then be utilized as a cheap conservative management of CTS. Study design: Two-groups randomized single-blind interventional study.

Detailed Description
-----------------
Background: Carpal Tunnel Syndrome (CTS) is the most common compressive neuropathy in the upper limb. It considerably impairs patient's quality of life and generates important social consequences due to the lost of productivity and the cost of treatments. Both surgical and conservative treatment are utilized for CTS management. Manipulative treatment is a conservative, non-drug and cheap management option which can be proposed, but by now, treatment guidelines and reviews do not recommend it due to lack of evidence to assess his efficacy. Hypothesis: Manipulative treatment can relieve patients of discomfort and dysfunction and then be utilized as a cheap conservative management of CTS. Study design: Two-groups randomized single-blind interventional study. Methods: Sixty-six patients reporting CTS symptoms that are confirmed by clinical exam and nerve conduction studies will be included. Participants will be randomized in two arms, one receiving manipulative treatment and one receiving simulated manipulative treatment (1/week for 4 weeks). The main outcome measures will be the DASH questionnaire, the Boston Carpal Tunnel Syndrome Questionnaire, patient estimate on Visual Analog Scale for pain and the EuroQol-5D scale. All outcomes measures will be administrated to participants before the first manipulation, after the last session (4 weeks) and 12 weeks after the baseline measure.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Boston Carpal Tunnel Questionnaire | self-administered questionnaire for the assessment of severity of symptoms and functional status in patients who have carpal tunnel syndrome. It has two distinct scales : a symptom-severity scale (11 - Page 2 of 3 [DRAFT] - items) and a functional-status scale (8 items). It has been validated and demonstrated to show good responsiveness and reliability in evaluating outcome after carpal tunnel release. The Spanish version has been validated | Baseline, 4 weeks, 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in DASH Outcome Measure | 30-item, self-report questionnaire designed to measure physical function and symptoms in people with a musculoskeletal disorder of the upper limb. It showed a large degree of responsiveness after CTS treatment and the Spanish version has been validated | Baseline, 4 weeks, 12 weeks | 
| Change in Visual Analog Scale for pain | VAS has eleven points from 0 to 10, being 0 no pain at all, and 10 the worst pain could ever be imagined | Baseline, 4 weeks, 12 weeks | 
| Change in EuroQol-5D scale | Quality-of-life's measure instrument which consists of a combination of a 5 items questionnaire and a Visual analogue scale. Both validity and responsiveness have been demonstrated in patients with chronic pain, and it has been evaluated in patients with CTS symptoms. The Spanish version has been validated | Baseline, 4 weeks, 12 weeks | 
| Change in strength (Dynamometer) | Measuring pulp pinch strength with digits I and II | Baseline, 4 weeks, 12 weeks |
