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

Condition or disease Intervention/treatment Phase
Carpal Tunnel Syndrome Other: Mirror therapy Other: Placebo group Not Applicable

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.

Primary Purpose: Treatment
Official Title: Effects of Mirror Therapy on Pain and Function on Bilateral Carpal Tunnel Syndrom (MTSTC)
Actual Study Start Date : October 2015
Actual Primary Completion Date : January 2017
Actual Study Completion Date : February 2017

Arm Intervention/treatment
Experimental: Mirror therapy group
Mirror therapy group: exercises looking at the reflection in the mirror of the hand moving
Other: Mirror therapy
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.
Other Names:
  • Mirror visual feedback
  • Mirror box therapy

Placebo Comparator: Placebo group
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
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.

Primary Outcome Measures :
  1. To evaluate changes on pain [ Time Frame: Changes in 8 weeks ]
    Evaluation on pain through McGill Pain Questionnaire This questionnaire is self-administered.

Secondary Outcome Measures :
  1. To evaluate changes on the function of the upper limb. [ Time Frame: Changes in 8 weeks ]
    Evaluation on function through disabilities of the arm, shoulder and hand questionnaire (DASH)

Other Outcome Measures:
  1. To evaluate catastrophism associated with pain. [ Time Frame: Day 0 of the study ]
    Evaluation through Pain Catastrophizing Scale This questionnaire is self-administered
