Effects of Mirror Therapy on Pain and Function on Bilateral Carpal Tunnel Syndrom

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to evaluate pain and function after mirror therapy as well as level of catastrophism in bilateral carpal tunnel syndrome patients

Detailed Description
-----------------
The sample calculation was performed based on the previous pilot study, in which 10 subjects were included. Through this study, a statistically significant effect on the variables analyzed was demonstrated. Therefore, it was determined to duplicate the initial sample to confirm the effect previously studied, assuming losses of 20%. Thus, the value of n for the clinical trial is 20 subjects.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Mirror therapy group<br>Mirror therapy group: exercises looking at the reflection in the mirror of the hand moving | Other: Mirror therapy<br>* The treatment proposed for the mirror group consisted of 8 weeks of treatment, performing a series of exercises 2 times a day / 4 times a week. The first 4 weeks the treatment was done in the hospital next to the physiotherapist for 2-3 days a week, and the next 4 weeks the patient performed the exercises following the same guidelines at home.<br>* Other names: Mirror box therapy;|
| Placebo Comparator: Placebo group<br>Placebo group: exercises performed with the mirror turned to avoid the reflection of the hand and looking at the hand that did not remain hidden. | Other: Placebo group<br>* The treatment was the same than proposed in inference group but with a mirror covered to avoid the reflexion on the hand and looking at the hand that did not remain hidden.<br>|
