What is the term for a medial longitudinal arch that is lost only on weight bearing?

Question

Quizplus · Accepted Answer

A supple flatfoot is characterized by a medial longitudinal arch that collapses during weight-bearing but can be restored with non-weight-bearing. On the other hand, a rigid flatfoot is one that has a fixed collapsed arch even during non-weight-bearing. The windlass mechanism refers to the tightening of the plantar fascia during dorsiflexion to maintain the arch. Oversupinator is not related to the medial longitudinal arch of the foot.
