Purpose: This study is to identify the effect of Ankle Joint Taping applied to patients with chronic hemiplegia on their gait velocity and joint angles. Methods: We randomly extracted a clinical sample from 30 patients with hemiplegia resulting from stroke and classified them into two groups of a control group including 15 patients offered a regular therapeutic exercise and a test group including 15 patients offered taping. We also conducted the comparative analysis and pretest of the affected ankle joint angles by the normal characteristics of all subjects, Time to up and go test (TUG), 3D movement analyzer before the intervention. We applied taping to a test group for eight hours a day, five days a week during two weeks and conducted the comparative analysis of the gait velocity and the affected ankle joint angles by a comparison between and within two groups of before and after the intervention by conducting a posttest after the intervention. The result is as followings. Results: It indicated that there was a significantly decreased time with the increased gait velocity that a test according to a result of comparing the gait velocity within two groups (p<0.05). It indicated that there was a significantly increased angle in a comparison within two groups of test that inversion angle of a control group according to a result of comparing the ankle joint angles by 3D movement analyzer within groups (p<0.05). Conclusion: We found that TUG will help patients walk independently because it met a test group`s need in the change of the gait velocity between two groups by recording less than 14 seconds which is the standard of using assistive aids and also found that ankle joint taping will help the joints prevent their function change considering that a control group showed an increased inversion angle in the change of the ankle joint within two groups.
