About

Objective: To comparing the effects of unilateral and bilateral mirror therapy on upper extremity function of stroke at acute stage. We hypothesize there are different effects between unilateral and bilateral mirror therapy on stroke patients at acute stage. Method: Patients with unilateral stroke and the onset within one month will be recruited and then randomly allocated to one of the three groups (including unilateral mirror therapy, bilateral mirror therapy, and conventional occupational therapy). Patient will receive 20 consecutive sessions of intervention (5 time per week, totally 4 weeks) and assessments before and after the intervention within one week. In each intervention session, patients will receive 30 minutes unilateral or bilateral mirror therapy depending on their allocated groups and then 30 conventional occupational therapy. The patients recruited in the conventional occupational therapy group will receive 60 minute conventional therapy. The outcome measures at pre- and post-treatment will including the Fugl-Meyer Assessment for upper extremity (FMA-UE), the Modified Ashworth Scale (MAS), the Jamar Hydraulic Hand Dynamometer, the Chedoke Arm and Hand Activity Inventory (CAHAI), the Revised Nottingham Sensory Assessment (rNSA), and Functional Independence Measurement (FIM).
