Purpose : The purpose of this study was to find out the effect of closed kinetic chain exercise with functional electrical stimulation(FES) of the gluteus medius on gait in stroke. Methods : 30 hemiplegic patients voluntarily participated in this study. Subjects were divided into experimental group(n=15) and control group(n=15). Experimental group was given closed kinetic chain exercise with FES of the gluteus medius and control group was given only closed kinetic chain exercise for 4 weeks. All subjects were measured 10m-walking speed, cadence, functional walking category(FAC) and modified motor assessment scale(MMAS) before and after intervention. Results : In experimental group, gait velocity, cadence, FAC and MMAS showed significant difference between pre and post test(p<.05). In control group, gait velocity, cadence and FAC showed significant difference between pre and post test(p<.05). Before intervention, gait velocity, cadence, FAC and MMAS were not significant difference between experimental group and control group(p>.05), but after intervention, gait velocity, FAC and MMAS were significant difference(p<.05). Conclusion : This study show that closed kinetic chain exercise with functional electrical stimulation(FES) of the gluteus medius is beneficial intervention for increase the wlking ability in stroke.
