Objective To identify the pressure relieving effect of adding a pelvic well pad, a firm pad that is cut in the ischial area, to a wheelchair cushion on the ischium. Methods Medical records of 77 individuals with SCI, who underwent interface pressure mapping of the buttockthigh area, were retrospectively reviewed. The pelvic well pad is a 2.5-cm thick firm pad and has a cut in the ischial area. Expecting additional pressure relief, it can be inserted under a wheelchair cushion. Subjects underwent interface pressure mapping in the subject’s wheelchair utilizing the subject’s pre-existing pressure relieving cushion and subsequently on a combination of a pelvic well pad and the cushion. The average pressure, peak pressure, and contact area of the buttock-thigh were evaluated. Results Adding a pelvic well pad, under the pressure relieving cushion, resulted in a decrease in the average and peak pressures and increase in the contact area of the buttock-thigh area when compared with applying only pressure relieving cushions (p<0.05). The mean of the average pressure decreased from 46.10±10.26 to 44.09±9.92 mmHg and peak pressure decreased from 155.03±48.02 to 131.42±45.86 mmHg when adding a pelvic well pad. The mean of the contact area increased from 1,136.44±262.46 to 1,216.99±255.29 cm2. Conclusion When a pelvic well pad was applied, in addition to a pre-existing pressure relieving cushion, the average and peak pressures of the buttock-thigh area decreased and the contact area increased. These results suggest that adding a pelvic well pad to wheelchair cushion may be effective in preventing a pressure ulcer of the buttock area.
