BACKGROUND: The exergaming training involves motor as well as cognitive stimulation. Although exergame studies have been reported to have benefits in motor function, the effects of exergames on improving cognitive function remain inconclusive. Moreover, no study has been reported in stroke patients.
AIM: The objective of this study was to compare the cognitive effects of 2 weight-shifting controlled exergaming systems and conventional weight- shifting training in patients with chronic stroke.
DESIGN: This was a single-blind randomized controlled trial.
SETTING: All participants were recruited from a rehabilitation department of a tertiary hospital.
POPULATION: Patients (N.=37) with chronic hemiplegic stroke.
METHODS: Patients were randomly allocated to one of the Wii Fit, Tetrax biofeedback, or conventional weight-shifting training groups. All interventions were administered 30 minutes per session, twice a week for 12 weeks. We used total score and the 9 domain scores of Cognitive Abilities Screening Instrument Chinese version (CASI C-2.0), and Berg Balance Scale (BBS) as the outcome measures. The outcome measures were assessed before and after training, and at 3 months follow-up.
RESULTS: There were no significant differences among the 3 groups in the percentage of change in CASI total score and BBS, either post intervention or at the 3-month follow-up. At assessing the percentage of change in each domain of CASI, we found significant differences among the 3 groups in the abstraction/judgment domain after intervention (Wii Fit 16.25 [9.77, 37.50]% vs. Tetrax 0.00 [-10.00, 0.00]% vs. weight-shift 11.00 [0.00, 14.38]%, P=0.01], and at the 3-month follow-up (Wii Fit 20.00 [10.83, 31.25]% vs. Tetrax -10.00 [-11.11, 10.00]% vs. weight-shifting 0.00 [-2.27, 11.46]%, P=0.01). The differences came from the differences between Wii Fit and Tetrax mainly. There were significant differences among the 3 groups in language domain after intervention (Wii Fit 0.00 [0.00, 5.54]% vs. Tetrax 0.00 [-3.00, 0.00]% vs. weight-shift 0.00 [0.00, 0.00]%, P=0.045), but not at the 3-month follow-up (P=0.13). There was no correlation between the percentage of change in BBS and CASI total score postintervention ( r=-0.15 P=0.38).
CONCLUSIONS: Wii Fit games training might be beneficial in some cognitive functions, such as abstraction/judgment, language in patients with chronic stroke. Wii Fit games, the commercial entertainment exergames, had superior effect in abstract/judgment and language domains as compared to the rehabilitation exergame (Tetrax balance system). Hence, Wii Fit games might be considered as a tool in post-stroke cognitive rehabilitation programs.
