Shock absorption.
Abnormal shock is a major cause of chronic and overuse injuries to all aspects of the lower extremity. The two major causes of abnormal shock are (1) decreased fat pad under the calcaneus and (2) dysfunction of the subtalar joint pronation mechanism during contact. Enough literature now exists to indicate that podiatrists should provide prophylactic therapy for patients that exhibit abnormal shock during contact before symptomatology in the lower extremity or spine exhibits itself.
