Pathomechanical foot types usually refer to structural deformities that cause the foot to compensate upon weight-bearing. When the foot is non weight-bearing and off the ground, a structural deformity is not an issue. However, because we rely so heavily on the proper functioning of our feet in everyday life, we need to accommodate structural problems so that we can move forward in locomotion with comfort. The foot needs to adjust to varying terrain and accept the body’s weight from above. If there is a structural problem (meaning fixed in a specific position) the foot must compensate in order to move the body forward in locomotion. Below, we have outlined the five most common structural deformities.
Note: Compensated - refers to a change in the structural alignment or position of one part of the foot to neutralize the effect of a structural problem in another part of the foot. Uncompensated – refers to the structural position of the whole foot or one part of the foot in a non weight-bearing situation.
