Twenty wheelchair court-sport athletes (age: 32 ± 11 years old) performed one submaximal propulsion trial in their sports-specific wheelchair at 1.67 m/s for 3 min and two 10 s sprints on a dual-roller ergometer. The Performance Corrected Wheelchair User's Shoulder Pain Index (PC-WUSPI) assessed shoulder pain. During the acceleration phase of wheelchair sprinting, participants propelled with significantly longer push times, larger forces, and thorax flexion range of motion (ROM) than both the maximal velocity phase of sprinting and submaximal propulsion. Participants displayed significantly greater peak glenohScandinavian journal of medicine & science in sports1213-1223https://www.ebi.ac.uk/biostudies/studies/S-EPMC9545165biostudies-literatureAlterations in shoulder kinematics are associated with shoulder pain during wheelchair propulsion sprints.PMC9545165Mason BSGoosey-Tolfrey VLBriley SJVegter RJKfalseAlterations in shoulder kinematics are associated with shoulder pain during wheelchair propulsion sprints.The study purpose was to examine the biomechanical characteristics of sports wheelchair propulsion and determine biomechanical associations with shoulder pain in wheelchair athletes.
