Abstract

Purpose: The purpose of this study was to determine the effects of action observation training on lower limb muscle activity and dynamic balance in chronic stroke patients. Methods: This study evaluated 20 chronic stroke patients who were divided randomly into a control and an experimental group comprising 10 patients each. Both the experimental group and the control group performed the general exercise therapy provided by the hospital, but the experimental group also performed action observation training. Lower limb muscle activity was measured with a surface electromyograph, and dynamic balance was measured with the Timed Up and Go test and the 10-meter walk test. The paired t-test was used to compare the groups before and after the experiment. Furthermore, the independent t-test was used to assess differences in the degree of change between the two groups before and after the experiment. Results: The within-group comparisons for both the experimental group and the control group showed significant differences in muscle activity and dynamic balance (p<0.05). In a comparison between the groups, the differences in the muscle activity and dynamic balance of the experimental group appeared significant compared with those of the control group (p<0.05). Conclusion: The study results indicate that action observation training is effective in improving the muscle activity and dynamic balance of chronic stroke patients.
