The purpose of this study was to investigate to effects of temporary visual feedback training using Fresnel prism glasses on balance in hemiplegic stroke patients without neglect. 19 hemiplegic stroke patients were randomly assigned to the experimental group (n=10) and the control group (n=9). Subjects of the control group performed balance and gait training, and subjects of the experimental group performed balance and gait training with a Fresnel prism glasses for 30 minutes each. All subjects performed motor-free visual perception test (MVPT) before intervention to measure visual perception. Functional reaching test (FRT) and gait parameters were performed before and after intervention. As a result, MVPT was no significant difference between the groups (p>0.05). FRT showed significant difference between the groups (p<0.05). In gait parameters, the swing time decreased and the single support time on the affected side increased. In summarizing the results of this study, the application of temporary Fresnel prism glasses had the effect to improve the balance ability in hemiplegic stroke patients without neglect. Therefore, Fresnel prism glasses could be favorably used as an intervention tool for improving balance in hemiplegic stroke patients without neglect.
