The effects of visual feedback balance training on the pain and physical function of patients with chronic degenerative knee arthritis

[Purpose] This study aimed to investigate the effects of visual feedback balance training on the pain and dysfunction of patients with chronic degenerative knee arthritis. [Participants and Methods] Twenty-six patients with chronic degenerative knee arthritis participated in this study; the control group (n=13) performed muscle strength training and the experimental group (n=13) performed visual feedback balance training. General physical therapy was applied to both groups three times a week for eight weeks. The visual analog scale was used to measure the patient’s pain scale, and the K-WOMAC (Korean Western Ontario and McMaster Universities Osteoarthritis Index) was used as a tool to evaluate their physical function. [Results] In the intra-group comparisons, significant decreases in the visual analog scale and the K-WOMAC were observed for the control group and the experimental group. No significant difference was found in the inter-group comparisons after treatment. [Conclusion] Visual feedback balance training is considered to be an effective intervention method for improving pain and dysfunction in patients with chronic degenerative knee arthritis.
