Abstract
Objective: To compare the efficacy of a virtual reality commercial gaming device, Nintendo wii (NW) with conventional therapy and customary care in facilitating upper limb recovery after stroke.
Design: Randomized, controlled, single-blinded study. Setting: Tertiary rehabilitation center.
Participants: 105 subjects admitted to in inpatient rehabilitation program within 6 weeks of stroke onset.
Interventions: Subjects were randomly assigned to one of three groups of upper limb exercises: (1) NW gaming; (2) conventional therapy; (3) control. NW gaming and conventional therapy were provided fourtimes a week for 3 weeks.
Main outcome measure(s): The main outcome measure was Fugl-Meyer assessment (FMA) of upper limb function. Secondary outcome measures included Action Research Arm Test, Functional Independence Measure, and Stroke Impact Scale. These measures were assessed at baseline, completion of intervention (week 3) and at 4 weeks and 8 weeks after completion of intervention. The primary outcome measure was the change in FMA scores at completion of intervention.
Results: The mean age was 57.5±9.8 years, and subjects were enrolled at a mean of 13.7±8.9 days after stroke. The mean baseline FMA score was 16.4±14.2. There was no difference in FMA scores between all 3 groups at the end of intervention, and at 4 and 8 weeks after completion of intervention. Similar findings were also noted for the secondary outcome measures.
Conclusion(s): Twelve sessions of augmented upper limb exercises via NW gaming or conventional therapy over a 3-week period was not effective in enhancing upper limb motor recovery compared to control.
