Abstract
Joint protection for hand osteoarthritis (OA) relies on theory but not empirical evidence. This study focuses on how hand positioning and nonskid materials influence forces, pain, and perceived effort during jar opening. New data challenge the belief that nonskid materials alone reduce hand forces.
