Purpose : We aimed to determine whether improvements in balance, gait, and motor function were different when the same exercise was performed, with and without mirror therapy, by patients with subacute stroke using the affected and unaffected lower limbs.
Methods : Eight patients with subacute stroke were randomly divided into experimental groups 1, 2 and the control group. A mirror therapy program was performed with group 1 using the unaffected lower limb and group 2 the affected lower limb. The exercise lasted 30 min per session, five times weekly, for 4 weeks. The control group did not perform the exercises. BT-4, BBS, POMA, 10MWT, and BRS were used to evaluate balance, gait, and motor function before and after the intervention.
Results : Post-intervention analysis showed that all three groups had higher BBS scores. After training, the postural sway in groups 1 and 2 decreased in the post eye opened and closed positions; that of the control group increased. The scores of two subjects in group 1 increased by 4 and 5 points in POMA, resulting in significant changes compared to those in the other groups. No group showed significant results in 10MWT. BRS improved in all subjects in group 1 from BRS 2 to 1 and in only one subject in group 2 there was no change in the control group.
Conclusion : Static and dynamic balance and significant results are noted in POMA, BBS, but not gait velocity. Therefore, mirror therapy seems to show a positive change in subacute patients, but the research results are not clear and the difference between groups is unknown due to the small number of subjects. The effects of mirror therapy and exercise therapy should be compared using more subjects in future.
