Wheelchair_cushion
Wheelchair cushions are cushions specifically designed to provide comfort and protection against injury for wheelchair users. They also aid in properly positioning the user in the correct posture.
Wheelchair users are at great risk for pressure sores.[1] A number of factors are included in the formation of these ulcers including:
- Insufficient vascularization in areas of high pressure, typically under bony prominences.[2]
- The collection of sweat on the skin due to inadequate air flow.[3]
- The presence of local areas of elevated temperature.[4]
- Shear stresses on the skin.[5]
A number of studies point to interface pressure between the body and the seating surface as the primary contributor to the formation of pressure sores.[1] In response, manufacturers have developed a number of wheelchair seat cushion alternatives. Over 200 models of wheelchair cushions were on the market[where?] as of 2001.[6][needs update]
