OBJECTIVES: To investigate the acceptability and potential efficacy of two
commercial video games for improving upper extremity function after stroke in
order to inform future sample size and study design.
DESIGN: A controlled
clinical trial design using sequential allocation into groups. SETTING: A
clinical occupational therapy department. SUBJECTS: Twenty-four first-stroke
patients. INTERVENTIONS: Patients were assigned to one of three groups:
conventional group, Wii group, and XaviX group. In addition to regular one-hour
conventional rehabilitation, each group received an additional half-hour of upper
extremity exercises via conventional devices, Wii games, or XaviX games, for
eight weeks. MAIN MEASURES: The Fugl-Meyer Assessment of motor function, Box and
Block Test of Manual Dexterity, Functional Independence Measure, and upper
extremity range of motion were used at baseline and postintervention. Also, a
questionnaire was used to assess motivation and enjoyment. RESULTS: The effect
size of differences in change scores between the Wii and conventional groups
ranged from 0.71 (SD 0.59) to 0.28 (SD 0.58), on the Fugl-Meyer Assessment of
motor function (d = 0.74) was larger than that between the XaviX and conventional
groups, ranged from 0.44 (SD 0.49) to 0.28 (SD 0.58) (d = 0.30). Patient
enjoyment was significantly greater in the video game groups (Wii mean 4.25, SD
0.89; XaviX mean 4.38, SD 0.52) than in the conventional group (mean 2.25, SD
0.89, F = 18.55, p < 0.001), but motivation was not significantly different
across groups. CONCLUSION: Patients were positive to using video games in
rehabilitation. A sample size of 72 patients (24 per group) would be appropriate for a full study.
