What is a common problem associated with incorrect donning of a liner?

Pistoning of the limb is a common problem associated with incorrect donning of a liner because it often results from improper positioning or fit of the prosthetic components. When a liner is not donned correctly, it can create a gap between the residual limb and the prosthesis. This gap leads to a situation where the limb does not remain securely in place during movement, causing it to move up and down within the socket — a phenomenon known as pistoning. This movement can result in discomfort, skin irritation, and ineffective weight distribution, ultimately compromising the overall functionality and comfort of the prosthetic device.

In contrast, excessive perspiration is typically a result of other factors such as the materials used in the liner or the environment, rather than donning technique. Reduced limb length does not occur due to incorrect donning but rather through surgical decisions or changes in limb structure post-amputation. Poor circulation, while an important consideration for amputees, is usually related to vascular health or the tightness of the prosthesis rather than the specifics of how the liner is put on.
