Abstract
Manual wheelchairs are widely used by people with different physical disabilities. However, handrim propelled wheelchair locomotion is inefficient and biomechanically unfavorable, as evidenced by several studies in the literature. In this context, this study investigates circular hand trajectories within the physiological workspace of the upper extremity that are biomechanically more favorable for propulsion. We used an OpenSim musculoskeletal model of the upper extremity and a mechanical work-based performance criterion. So far, suitable locations of 0.1 m radius circumferences have been determined.
