Résumé : |
Objective To assess the efficacy of an off-loading wheelchair seat cushion in removing pressure from high-risk ischial tuberosities and the coccyx/sacrum in wheelchair sitting. Design Repeated-measures design. Setting Private research laboratory. Participants Manual wheelchair users with chronic spinal cord injuries (N=10). Interventions Three configurations of an off-loading wheelchair seat cushion compared with a flotation style (10-cm air inflation) wheelchair seat cushion. Main Outcome Measures Outcome measures included peak pressure index (PPI), ischial tuberosity peak pressures, and the dispersion index or ratio of pressures under the ischial and sacral regions to the total of all pressures recorded. Results PPI and ischial tuberosities peak pressure ranged from a low of 39+18 and 68+46mmHg in the fully off-loaded cushion to a high of 97+30 and 106+34mmHg, respectively, for the flotation style cushion (2-way analysis of variance main effect across 4 conditions, P<.001 dispersion index ranged from a low of in the fully off-loaded cushion to high flotation style cushion. pairwise comparisons yielded significance all cushion-pair analyses after multiple corrections> Conclusions The force-removal approach of this orthotic off-loading cushion design effectively reduces a known extrinsic risk factor for pressure ulcersinterface pressurein the high-risk ischial tuberosity and sacral/coccygeal regions of the buttocks. |
