When aligning the prosthetic socket posterior to the foot, where will the forces in the socket increase?

When aligning the prosthetic socket posterior to the foot, the forces within the socket will primarily increase in the anterior-proximal region.

This is due to the biomechanics of prosthetic alignment, where the positioning of the socket influences the distribution of load and support during weight-bearing activities such as standing and walking. Aligning the socket posteriorly creates a lever effect that shifts the center of pressure forward. As weight is applied, this anterior shift increases the force that the socket exerts in the anterior-proximal area. This adjustment helps in stabilizing the residual limb within the socket and provides better control during ambulation.

The other options do not align with the correct mechanics of load distribution in this scenario. While the posterior-distal area may experience some pressure, it is not where the primary force increase occurs when the socket is aligned in this manner. The lateral and medial positions also do not correspond to the typical response in force distribution related to posterior alignment, as they are more influenced by side pressures during gait and stance stability rather than anterior force maximization.
