Mirror Therapy Efficacy in Upper Limb Rehabilitation Early After Stroke

This study evaluates the effects of mirror therapy on upper-limb motor impairment in stroke patients early after their cerebrovascular accident. In recent years mirror therapy has been used in stroke rehabilitation, both to ease motor (e.g., upper limb impairment) and cognitive (e.g., spatial neglect) recovery. To note, mirror therapy is a simple and inexpensive treatment that patients can practice independently and with no significant side effects. However, a recent review concluded that the currently evidence available is not enough to determine about the actual effectiveness of mirror therapy in stroke survivors. Moreover, at our knowledge, the majority of studies recruited chronic stroke patients while only a few trials recruited patients within few weeks after stroke. Therefore, further research is encouraged particularly early after stroke. In mirror therapy patients exercise their sound hand while it is reflected by a mirror placed at right angle to the patient's trunk. With this gambit, patients see two hands moving: their sound hand (i.e., the hand that is voluntarily moved) and the "avatar" of their impaired hand (i.e., the sound hand reflection in the mirror). In this assessor-blinded, randomized controlled trial half of participants receive mirror therapy .The other half receive sham therapy, in which the mirror is flipped so that the opaque surface face the sound arm. Mirror therapy and sham therapy are added to conventional rehabilitation. In the current work, we investigate the efficacy of mirror therapy on upper-limb recovery in early post-stroke patients.
