Abstract

Purpose
This study examined whether mirror therapy could improve the balance, gait, and motor function of patients with subacute stroke.
Methods
Thirty-three patients with subacute stroke were divided randomly into three groups: experimental group1, experimental group2, and the control group. The patients in experimental group1 performed a mirror therapy program on the unaffected side of the lower extremities, and the patients in experimental group2 performed mirror therapy on the affected side of the lower extremities. Both groups performed the exercise for 30 minutes per session, five times a week for four weeks. The control group did not receive mirror therapy. BBS, POMA, 10MWT, and the BRS were used to evaluate the balance, the quality of gait, gait speed, and the motor function before and after the intervention.
Results
The gait speed increased significantly in the experimental groups1 and 2 after the intervention. The control group showed no significant difference in the gait speed after the intervention. The change in gait speed before and after the intervention showed a significant difference among the groups. Experimental group1 showed a significant increase in the gait speed compared to that of the control group.
Conclusion
This study suggests that mirror therapy could be an effective intervention to improve the gait speed of patients with subacute stroke. On the other hand, there was no difference in the effectiveness of mirror therapy and therapeutic exercise on the balance, gait, and motor function.
