PURPOSE: The aim of this study was to determine the effects of proprioception exercise to decrease pain and increase the ability to balance by implementing visual feedback during early rehabilitation after total knee arthroplasty. SUBJECTS AND METHODS: In this study, 24 patients who receive a total knee arthroplasty were randomly and equally assigned to a visual feedback training group (VFT group) and a visual disuse group (control group). They performed visual feedback training using the My Fitness Trainer (MFT, Austria) for 20 minutes, three times per week for eight weeks. The patients' balance ability and pain was measured before and after the exercises. Pain was measured by the visual analogue scale (VAS). To assess balance ability, the anteroposterior and mediolateral directions on unstable ground was measured by using the MFT measurement system. RESULTS: The VFT group showed a significant decrease in VAS and an increase in balance ability within the group, as well as a significant increase in balance ability between groups when compared with the control group. CONCLUSION: Visual feedback training during the rehabilitation of patients who received a total knee arthroplasty will be useful in reducing pain and improving balance.
