Tilt-in-space on a power wheelchair is primarily used to provide pressure relief by redistributing pressure away from which area?

• A. From the ischial tuberosities to the posterior trunk
• B. From the heels to the toes
• C. From the thighs to the knees
• D. From the shoulders to the chest

Answer: (A)

Tilt-in-space is used to relieve pressure by shifting weight off the sit bones and redistributing contact toward the back of the chair. In a seated position, the ischial tuberosities bear most of the load, and prolonged pressure there can lead to tissue damage. By tilting the seat, the user’s weight moves toward the posterior trunk and backrest, increasing contact area and reducing pressure on the ischial tuberosities. The other areas listed aren’t the primary load in a seated wheelchair, and tilting in this way doesn’t target those regions in the same protective way.
