Objectives: To investigate the relationship between inter- face pressure and gender, body mass index (BMI), and seating positions, and to evaluate the implications for clinical practice. Design: Group design. Setting: Pressure mapping laboratory. Participants: Sixty-three student volunteers (44 women, 19 men; mean age, 22.25.1y). Interventions: Seated-interface pressure was measured us- ing the Force Sensing Array pressure mapping system. Seating positions used included recline (10°, 20°, 30°), foot support, and foot elevation. Main Outcome Measures: Interface pressure in the form of both average pressure (mean of the pressure sensor values) and maximum pressure (highest individual sensor value). Results: Both average and maximum pressures were inde- pendent of gender, while average pressure had a significant positive correlation with BMI (r.381, .01 level). Recline of the chair by 30° significantly reduced average pressure (P.001), whereas recline by 10° or 20° had no significant effect. Recline by 10°, 20°, and 30° did not significantly alter maximum pressure. Elevation of the feet on a footstool reduced average pressure to a level approaching statistical significance, while supporting participants' feet versus leaving them unsup- ported significantly increased average pressure at a 0°, 10°, 20°, and 30° recline (P.01) and maximum pressure at 0°, 10° (P.01), and 30° (P.05). Conclusions: Elevating clients' feet and reclining their chair by 30° reduced interface pressure and the associated risk of pressure ulcer development. Additional research is required, however, to replicate this study with participants at increased risk of pressure ulcer development. |
