Effects of Suspension on the Vibrations Experienced During Wheelchair Propulsion

Publication Date: 2007

Study examined the effect of front caster and rear wheel suspension on seat forces and head accelerations experienced by four manual wheelchair users during overground wheelchair propulsion. Tests were conducted with 1 rigid frame wheelchair (Quickie GPV) and 3 rear wheel suspension frame wheelchairs (Colours Boing, Invacare A4, and Quickie XTR), each instrumented to collect force components acting on the rider through the seat and backrest. Each subject propelled the instrumented chair through a test course at self-selected speeds. Time and frequency domain analysis was performed to examine the forces and accelerations experienced by the riders. Results were inconclusive; however, lesson learned from the tests will be applied to future research to generate more meaningful data. This paper was presented at the 2007 Annual Conference of the Rehabilitation Engineering & Assistive Technology Society of North America.
