Reliability of cushion construction for a low-cost pressure-reducing wheelchair cushion for less-resourced settings.

In less-resourced settings, 80% of people with spinal cord injuries die from pressure ulcer complications within two years. Appropriately constructed wheelchair cushions are effective in reducing incidence and severity of pressure ulcers. The Tuball is an inexpensive wheelchair cushion designed for users in less-resourced settings, which can be reproduced by local clinicians using locally sourced materials.
