Wheelchair Propulsion

People with paraplegia and tetraplegia often rely upon manual wheelchairs propulsionas their primary means of independent mobility. It has been reported that wheelchair propulsion efficiency ranges between 5% to 18% (Cooper et al. 2001) and that wheelchairs are difficult for many individuals to use effectively. Between 25% and 80% of wheelchair users experience wrist, elbow and shoulder injuries (Cooper et al. 2001). Pushrim biomechanics has been linked to upper extremity injuries (Boninger et al. 1999). Newer technologies continue to improve upon wheelchair propulsion efficiency through frame features.
