This study compared the short-term pressure-relieving ability of the three most commonly prescribed wheelchair cushions (Roho, Jay, Pindot) for a person with SCI. The number of pressure sensors registering at the buttock-cushion interface during wheelchair sitting was measured by the Xsensor Pressure Mapping System after 5 min of sitting. An alternating treatments research design, with an initial baseline and a final treatment phase ending with the most effective cushion for relieving pressure, was used for the clinical evaluation. Measurements were compared using visual inspection and a Wilcoxon signed ranks test. The number of pressure sensors that registered potential harmful levels of pressure at the buttock-cushion interface for the Roho cushion was significantly less than those of the Jay and Pindot cushions.
