A comparison of interface pressure readings to wheelchair cushions and positioning: a pilot study.

Full Abstract

Occupational therapists are often involved in assessing the seating needs of clients who have quadriplegia. One component of this process involves determining the appropriate use of wheelchair cushions and pressure relieving techniques in the prevention of pressure sores. The purpose of this study was to assess the effect of tilt and recline positioning and various wheelchair cushions on interface pressures at the ischial tuberosities and the sacrum of two subjects with C5 quadriplegia. In addition, interface pressures under bony prominences were assessed in the personal driving position (when the subject enters), neutral, 35 degree tilt, 45 degree tilt, and maximum recline (150 degrees). The results of this study indicate that for the two subjects evaluated, higher average interface pressures at the ischial tuberosities were obtained when using one of the three cushions under scrutiny. Furthermore, the general trend observed with both subjects is a reduction of pressure readings at the ischial tuberosities with tilt and recline positioning (especially with 45 degree tilt and 150 degree recline). The findings of this study are in keeping with previous studies which identified that individual and ongoing assessment is essential in providing the best cushion and pressure relief techniques for individuals.
