Effects of virtual balance training and conservative rehabilitation on balance in chronic stroke patients

Abstract

Objective: This study aimed to test the comparative efficacy of virtual balance training (VBT) and conservative rehabilitation (CR) relative to CR alone on balance in chronic stroke patients. Methods: Thirty patients with chronic stroke (>6-months post-stroke) were allocated into 2 groups (n=15) as Group CR and Group VBT. CR was performed for 60 min, 4 times a week, for 8 weeks in both groups. VBT was applied for 20 min, 4 times a week, for 8 weeks along with the CR, in Group VBT. Brunnstrom motor recovery (BMR) stage, spasticity degrees, Functional Ambulation Scale (FAS), Short Form-36 (SF-36) scale, Berg Balance Scale (BBS) in both groups were assessed before and after treatment. Mann-Whitney U, Wilcoxon signed rank tests were used to evaluate BBS data (p<0.05). Results: Although, no significant difference was observed between groups in terms of BBS scores, BMR stages, FAS scores, SF-36 scale scores, and spasticity degrees before and after treatment; significant improvements were observed in BBS scores, BMR stages, and FAS scores after treatment in both groups (p<0.05). Comparing the SF-36 subscale scores before and after treatment, significant differences were noted in emotional role limitation scores for Group VBT (p=0.03) and in pain scores for Group CR (p=0.01). Conclusion: VBT along with the CR in chronic stroke patients was not superior to the CR alone, in terms of improving balance, motor recovery, ambulation level, and quality of life.
