What is a common prosthetic sock adjustment to manage residual limb settling?

• A. Add an additional one-ply sock to residual limb
• B. Remove all socks
• C. Switch to a different prosthetic type
• D. Increase socket depth

Answer: (A)

When a residual limb settles and loses volume, the socket becomes looser and pistoning can increase. The simplest and most common fix is to add an extra one-ply sock to the limb. This increases the fill between the limb and socket, restoring a snug, evenly distributed fit and better suspension without changing the prosthesis. Removing socks would worsen the looseness, and increasing socket depth or switching to a different prosthetic type are more drastic steps used when sock adjustments can’t maintain an proper fit.
