Abstract:

Study measured and compared shoulder joint forces and moments during manual wheelchair propulsion at a slow and a moderate speed. A motion analysis system captured movements of the upper limbs and the SmartWheel system simultaneously recorded pushrim kinetics as 27 individuals propelled their wheelchairs at 2 constant speeds: 0.9m/s (2 mi/h) and 1.8 m/s (4 mi/h). Analysis revealed that all shoulder parameters were stable and consistent between strokes and speeds. The shoulder exhibited a greater range of motion and forces and moments at the shoulder were greater during the faster speed trial. Peak posterior forces occurred near the end of the propulsion phase, and at the same time, the shoulder was maximally flexed and minimally abducted.
