People with tetraplegia have weakness in their arms that can cause difficulties with wheelchair propulsion. Because of their poor muscular performance, maximizing their propulsion efficiency is important. We studied wheelchair propulsion at four different axle positions in people with chronic cervical 6 tetraplegia. The wheelchair axle position affects speed, acceleration, stroke frequency, and shoulder range of motion. We found that the up and forward axle position resulted in a more conducive position to stroke frequency than the other positions we analyzed.
