The Navicular Drop Test is a physical exam used to evaluate the arch of the foot and diagnose conditions such as plantar fasciitis. During the test, the patient stands barefoot on a flat surface and the practitioner palpates (feels) the navicular bone, which is located on the top of the arch. The patient then drops their arch by pressing down with their forefoot and heel, and the practitioner measures the difference in height between the navicular bone before and after
