Valgus bracing affords short-term treatment solution across walking and sit-to-stand activities.

Since activities of daily living do not exist in isolation this prospective study examined biomechanical function during level walking and sit-to-stand activities over two months of brace use by subjects with varying grades of knee osteoarthritis. Kinematic and kinetic data were collected using infrared cameras and force platforms; clinical scores compared perceived and measured functional effects. There was no significant change in pain for any grades of OA but activity levels were significantly higher at one month in the moderate OA grades and at two months for the low OA grades. Mechanical constraints and changes in movement strategies were consistent across tasks and OA grade. This study provides valuable data for further studies aimed at refining the use and optimization of valgus bracing efficacy.
