108 patients suffering from osteoarthritis of the knee were randomized to receive one of two non-weight bearing exercise programs. One program trained proprioceptive tasks, while the other focused on quadriceps strength. The purpose of this study was to examine the effects of these training modalities on WOMAC-pain and function scores, as well as assess the walking speed. The results indicated that both training interventions produced improvements in WOMAC-pain and -function scores from the baseline measures, while proprioceptive training provided improvements in walking speed on select surfaces.
