Abstract

|
|
Purpose: This study aimed to determine the effects of sensory feedback training of the ankle with visuoperceptual stimulation on static balance and gait functions in patients with chronic post-stroke hemiparesis.
Methods: This study included 16 patients with chronic post-stroke hemiparesis. The subjects were randomly assigned toeither the experimental group (EG) or the control group (CG), with 8 subjects in each group. All the subjects received a routine physical therapy. The EG subjects received a 30-min sensory feedback training for the foot and ankle with visuoperceptual stimulation by using Tetrax Portable Multiple System. This training was conducted 3 times a week for 4 weeks. The scores of balance ability, timed up and go (TUG), and dynamic gait index (DGI) were assessed before and after the intervention.
Results: In the EG, the scores of static balance, TUG, and DGI obtained afterthe intervention significantly differed from those obtained before the intervention (p<0.05). Further, in the EG, a significant difference was noted in the rate of change of all the variables when compared with those of the CG (p<0.05). However, in the CG, post-intervention score were only significantly different for DGI.
Conclusion: Our findings indicate that the sensory feedback training with visuoperceptual stimulation improves balance and gait functions of patients with chronic post-stroke hemiparesis. Further studies are needed to generalize the results of this study.
