title: Activity positioning and ischial tuberosity pressure: a pilot study.
abstract: Ipsilateral ischial tuberosity pressure of 12 subjects seated in wheelchairs was measured during reach to an activity positioned on both an upright and a flat plane. Ischial tuberosity pressure during cross-body, forward, and lateral reach was measured with a static pressure measurement device. Differences between flat-plane readings and upright-plane readings were analyzed with a t test; no significant difference was obtained. A repeated-measures analysis of variance revealed significant differences in ischial tuberosity pressure between cross-body, forward, and lateral reach in the flat plane activity. However, no significant difference was found between cross-body, forward, and lateral reach in the upright-plane activity. Results of this study support the theory that forward and lateral positioning of activity can supplement standard techniques for relieving pressure.
