Which socket adjustment would likely increase pressure on the lateral-distal area?

Increasing pressure on the lateral-distal area of a prosthetic socket is influenced by the alignment and position of the foot. When the foot is positioned in inversion, which means it tilts inward, it can shift the weight distribution and the center of pressure more towards the lateral side of the foot.

Inversion causes the foot to bring its lateral side closer to the ground while increasing the pressure exerted on the lateral-distal aspect of the socket. This positioning affects the way forces are transmitted through the socket during activities such as standing or walking, leading to increased lateral pressure.

In contrast, foot eversion would have the opposite effect, causing increased pressure on the medial side, while dorsiflexion and plantarflexion impact other areas of the socket rather than specifically increasing pressure on the lateral-distal section. Dorsiflexion tends to pull the socket away from the distal regions, and plantarflexion may shift weight toward the anterior or medial aspects. Therefore, the correct choice of foot inversion directly correlates with increasing pressure on the lateral-distal area of the prosthetic socket.
