Elevating leg rests in a wheelchair are indicated for which condition?

• A. Improve trunk stability
• B. To reduce pressure sores
• C. Edema
• D. Increase speed

Answer: (C)

Elevating leg rests are used to help move excess fluid out of the legs by improving venous and lymphatic return. When the legs are elevated, gravity aids the drainage of interstitial fluid back toward the heart, which reduces swelling in dependent limbs. This is particularly helpful in conditions that cause leg edema, such as venous insufficiency or postoperative swelling. It’s not primarily about trunk stability, which depends on core support and seating alignment, nor is it a primary strategy for preventing pressure sores—that relies more on pressure relief and skin care, though reducing edema can be a beneficial adjunct. It also won’t directly increase propulsion speed, which is related to upper-body strength and technique.
