Comparing Wheelchair Cushions for Effectiveness of Pressure Relief: A Pilot Study

Abstract

The purpose of this study was to determine if there were differences in pressure relieving abilities among six commonly prescribed wheelchair cushions and whether differences were related to the participant's body mass. In addition, the participant's perception of cushion comfort was investigated. A convenience sample of 40 adult wheelchair users were recruited from a rehabilitation hospital. Participants sat on the following six cushions for 5 minute periods: Flexseat, Jay 2, Pindot, ROHO High, ROHO Low, and Stimulite. Pressure measurements were recorded with the Xsensor Pressure Mapping System, a new instrument available to therapists. It was discovered that ROHO High and ROHO Low cushions were more effective in relieving pressure than the other cushions. Cushion pressure relieving abilities were largely dependent on the individual's body mass. ROHO cushions were also perceived to be more comfortable than all other cushions tested regardless of body mass and pressure relief.
