Study conducted to evaluate the effects of a carbon fiber wheelchair seatback on the propulsion performance of 21 people who were experienced in using manual wheelchairs. All of the participants had previously used either sling upholstery seatbacks or an aluminum seatback. The participants were monitored using the carbon fiber wheelchair seatback, while a number of parameters were measured, including: (1) steady-state power output, (2) fraction effective force, and (3) velocity. Secondary propulsion variables were also measured while the participants performed four tasks: (1) propelling a wheelchair on a stationary roller, (2) tile, (3) carpet, and (4) a ramp. All tests were conducted following a four-day acclimation period to the new carbon fiber seatback. The results indicated that carbon fiber seatbacks have implications to improve long-term propulsion performance.
