Background: The purpose of this study is to evaluate the efficacy of visual feedback training in enhancing balance and visual perception in people who have had a stroke.
Methods: Twenty-eight chronic stroke patients were randomly sampled and divided into two groups: visual feedback training group (n=15) and control group (n=13). For control group, 40-minute classical rehabilitation therapy was provided 5 times per week for 8 weeks. For experimental group, 40-minute visual feedback training twice per week and 40-minute classical rehabilitation therapy three times per week were provided for 8 weeks. Before and after the treatment, we performed Dynamic Balance Test (DBT), Static Balance Test (SBT), and Motor-Free Visual Perception Test-Vertical format (MVPT-V).
Results: In intra-group analysis, experimental group has shown significant improvement in DBT, SBT, and MVPT-V(p<.05). In inter-group analysis, experimental group has shown significantly better improvement than control group in distance of DBT, Y-speed of SBT, and MVPT-V(p<.05).
Conclusions: Visual feedback training may be helpful to improve not only dynamic and static balance, but also visual perception in stroke patients
