Pressure ulcer development is a common complication in people with spinal cord injury (SCI). Although not the sole cause, prolonged seating pressure is known to be a contributing factor to ulceration. Seating technologies use principles of immersion (how far the buttocks sink below the interface) and envelopment (how well the interface conforms to the buttock) to reduce interface pressure by increasing contact area; however, these properties can be difficult to achieve due to individual differences in body type. Effective support surfaces must accommodate a wide range of pathophysiological and body weight changes caused by SCI. The purpose of this project was to design and develop a contoured cushion that was both cost-effective and could be conveniently (re)configured per individual. We fulfilled these design requirements by using the rapid prototyping technique.
