Pressure sores, or decubitus ulcers, are caused by prolonged sitting in one position, deteriorated wheelchair cushions, sitting on a hard surface, skin moisture due to sweating, improper fitting prosthetics and adaptive equipment, and falls. The most commons sites for sores are the ischium, greater trochanter (hip), sacrum, and heels.

It is important to continuously check for pressure sores because usually the person is unable to feel them develop. Pressure sores will gradually worsen unless properly treated due to reduced blood flow to the area.

Prevention is the best way to treat a pressure sore. It is important to use well padded wheelchair cushions; wear absorbent clothing; ensure proper nutrition and proper hygiene; have prosthetic equipment and adaptive equipment routinely checked for proper fit; and perform arm pushups. Arm pushups should be held for 10 - 20 seconds, and performed every 20 minutes throughout the day.
