Abstract
Purpose: The purpose of this study was to investigate the effects of a weight-shifting dual-task intervention with visual feedback on balance in chronic stroke patients.
Methods: The study included 21 community-dwelling chronic stroke patients divided into an experimental group (n = 11) and a control group (n = 10). The experimental group performed a dual task that combined weight shifting with visual feedback and a cognitive task, which involved reading given words while shifting weight. The control group underwent only weight-shifting training with visual feedback without the cognitive task. The intervention was delivered twice a week for 4 weeks, with each session lasting 30 minutes. Balance was assessed using the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and a measure of weight imbalance. An independent t-test and a paired t-test were conducted for group comparisons, with the significance level set at p = .05.
Results: Both the experimental and control groups showed statistically significant improvements in BBS, TUG, and weight imbalance following the intervention (p < 0.05). The comparison of intervention-related changes between groups revealed significant differences in BBS and TUG scores (p < 0.05), but there was no statistically significant difference in weight imbalance between the groups.
Conclusion: The findings suggest that weight-shifting dual-task training with visual feedback may be a highly beneficial intervention for improving balance in community-dwelling stroke patients.
