This article aims to improve the knowledge and practice and also depicting the importance of standing balance in osteoarthritis patients. Clinical and scientific evidence of the therapeutic modalities is concerned with the postural balance depicting values on how to deal with pain.

The purpose of this study was to examine the relationship between standing balance increased through muscle-strengthening exercises and pain in knee osteoarthritis patients.

Thirty knee osteoarthritis patients were equally divided into a strengthening exercise group and an unstable exercise group. Before and after the six-week experiment, the visual analogue scale was measured, and bilateral one-leg standing tests were performed.

In both the strengthening exercise group and unstable exercise group, the bilateral one-leg standing time significantly increased after the six-week experiment. Regarding the visual analogue scale, a pain measurement scale, the strengthening exercise group had significantly decreased pain. The unstable exercise group also had decreased pain, but the decrease was not statistically significant.

In knee osteoarthritis patients, exercises using an unstable base of support and knee-extensor strengthening exercises with gradually increased loads had a positive effect on improving balance ability and decreasing pain.
