Abstract
INTRODUCTION The study was designed to investigate knee joint angular repositioning and postural control ability in conditions with vision and without vision. METHOD Twenty male persons(n=20) in twenties(without matters of orthopedic surgery) were volunteered to participate as subjects. RESULT Visual information(visual display on a screen) added accuracy of knee joint angular repositioning ability. The Postural sway increased significantly(p<.05) in conditions without vision. There was no significant relationship between knee joint angular repositioning and postural control ability. CONCLUSION The results confirmed that there was strong relationship between vision and knee angular repositioning ability, and balance performance.
