Comparison between hand-rim and power-assisted hand-rim propulsion while propelling on a treadmill.
Power-assisted wheelchair propulsion is effective in reducing potential risk factors of shoulder overuse injuries: intensity of shoulder loading, shoulder angles during force generation, shoulder range of motion and intensity of muscle activation.
The prescription of a power-assisted wheelchair seems to be indicated for subjects developing overuse injuries due to hand-rim propulsion or subjects with difficulties driving a hand-rim wheelchair primarily due to lack of upper-extremity power.
