Abstract
Purpose : The purpose of this study was to identify effects of virtual reality-based closed kinetic chain (CKC) exercise on lower extremity muscle activity in chronic stroke patients Methods : Subjects were assigned randomly either to VR+CKC exercise group (n=15) or the CKC exercise group (n=15). When the study began, both groups received conventional physical therapy five times per week. The VR+CKC exercise group received virtual reality programs and the CKC exercise group received close kinetic chain exercises. Each exercise program was performed for six weeks (5 times per weeks; 20 minutes per time). Participants were measured on lower extremity muscle activity using EMG. Results : There was a significant increase of muscle activity (%RVC) in vastus lateralis and vastus medialis. Conclusion : In this study, the virtual reality-based closed kinetic chain exercise program was an effective exercise for improving lower extremity muscle activity in chronic stroke patients.
