Participants propelled their own wheelchairs on a dynamometer at 3 distinct speeds (self-selected, 0.7 m/s, 1.1 m/s) for 3 minutes at each speed. Data from 10 experienced adult MWU with spinal cord injury (5 with shoulder pain 5 without shoulder pain) were analyzed in this study. This investigation examined intra-individual kinematic spatial variability during semi-circular wheelchair propulsion as a function of shoulder pain in MWU.
However wheelchair propulsion metrics related to shoulder pain are not clearly understood.
