The purpose of this study was to evaluate the effectiveness of force application and the load on the glenohumeral joint during handrim wheelchair propulsion at two different seat heights. In a research laboratory able-bodied male subjects propelled a wheelchair fitted with a SmartWheel on a treadmill at 3 different speeds, while power output was kept constant at 25 W by a pulley system. There was no effect of seat height on the propulsion effectiveness and the glenohumeral joint load under the current experimental conditions.
