What is the recommended maximum amount of sitting per hour for patients with limb loss?

• A. 20 minutes
• B. 30 minutes
• C. 45 minutes
• D. 40 minutes

Answer: (D)

Limiting how long you sit is important for people with limb loss because extended static sitting can lead to residual limb swelling, stiffness, and compromised circulation, all of which can affect comfort and prosthetic fit. The recommended maximum is 40 minutes of sitting per hour, with a break to stand up or move around for a few minutes. This helps keep blood flowing, reduces swelling, and supports better shaping of the residual limb so a prosthesis fits more comfortably. Sitting longer than 40 minutes increases pressure on the residual limb and surrounding tissues, raising the risk of edema and skin issues. Shorter blocks like 20 or 30 minutes would require more frequent interruptions, while 45 minutes would exceed the advised limit. The key idea is to intersperse sitting with movement to protect the limb and overall circulation.
