ABSTRACT

PURPOSE: This study examined the effects of the squat exercise combined with whole-body vibration (WBV) on proprioception in chronic stroke patients with knee hyperextension. METHODS: A randomized controlled trial was conducted with 25 chronic stroke patients assigned to either the experimental group (n = 11), performing squat exercises with WBV, or the control group (n = 14), performing only squat exercises. Both groups exercised five times per week for six weeks. Proprioception was assessed using the joint position sense test. Statistical analyses included the Friedman test for within-group comparisons, the Mann-Whitney U test for between-group differences, and the Wilcoxon signed-rank test for post-hoc analysis. Two-way ANOVA was used to assess the interaction effects of time and group. RESULTS: Both groups showed significant improvements in proprioception over the 6 weeks (p < .05). A greater improvement was observed between 0 and 6 weeks in the experimental group compared to the control group (p < .05). The Mann-Whitney U test confirmed a significant differece in proprioception enhancement, favoring the experimental group. CONCLUSION: The squat exercise combined with WBV effectively enhances proprioception in chronic stroke patients with knee hyperextension. This intervention demonstrates superior benefits compared to squat exercises alone and may serve as a valuable rehabilitation strategy for improving proprioceptive function.
