Purpose The purpose of this study was to evaluate the effects of Group Action Observation Training for patients on chronic stroke patient's balance and gait. Subjects 16 patients with chronic stroke were divided into collective training group and individual training group, enforced action observation and physical training. Methods The training program was for 4 weeks, 5 days a week, 30 minutes per session, and the session consisted of observation for 15 minutes and physical training for 15 minutes. BT4 and BBS were inspected for measuring the balancing ability, and in order to measuring the walking function 10MWT, F8WT, and DGI were inspected. All measurements and tests were implemented before and after the training. Results The results of this study, in case of the measurement with using BT4, the collective training group's posterior stability limit has significantly increased(p<.05). However, comparison of the variation according before and after training within groups was not significant between groups.(p<.05). In case of BBS, both groups had improved significantly before and after, however, there were no significant difference between the groups(p<.05). After training,

there was significant improvement within the groups with DGI score, time and the number of steps inside the evaluation items of 10MWT and F8WT. There was no significant difference in the comparison of the variation between groups(p<.05). Conclusion In order to increase opportunity to access effective treatment to more patients, various studies should be conducted related to the method of group action observation training.
