Background : The purpose of this study was to compare the effects of functional electrical stimulation(FES) on weight distribution and synchronization of the lower extremity of patients with post-stroke. Methods : They were randomly divided into two groups, 8 people in the experimental group and 7 people in the control group. A total of 15 subjects volunteered to participate in this study. experimental groups were treatment FES training on parallel bars and control groups were FES training on chair. They was performed for 15 minute, three times in a week, for the 6 weeks. Result : The experimental group The weight distribution A, B, C, D and synchronization AB, CD, AD, BC indicating changes in statistical significance(p<.05). However, the control group only showed significantly increased weight distribution A, C(p<.05). In a variation, experimental and control groups showed significantly increased weight distribution A, B, C and synchronization AD. Conclusion : These findings suggest that the FES training on parallel bars are effective in improving the weight distribution and synchronization of lower extremity of patients with post-stroke. Further study will be continued in this method of therapeutic exercise and additional physical therapy program.
