Effect of velocity on shoulder muscle recruitment patterns during wheelchair propulsion in nondisabled individuals: Pilot study

Liping Qi, PhD, et al.

Veterans with spinal cord injury or amputation often rely on manual wheelchairs for independent mobility over several decades. As a result, the joints and soft tissues of the upper limb (hand, arm, and shoulder) are repeatedly loaded as the manual wheelchair user goes about activities of everyday life. We used electromyography and kinematics to determine the influence of propulsion speed on the recruitment of shoulder muscles and fast and slow motor units during wheelchair propulsion. The results suggest that different muscle activation strategies occurred for different propulsion speeds.
