THE EFFECTS OF AN OVER-THE-COUNTER ORTHOTIC ON LOWER EXTREMITY KINEMATICS IN RECREATIONAL RUNNERS

Abstract

Abnormal foot mechanics during the stance phase of running may affect the kinematics of the lower extremities and predispose an individual to injuries of the foot, ankle, and knee. Custom made foot orthotics are often prescribed to correct abnormal mechanics during running by restoring dynamic stability to the closed chain of the lower extremity. However, custom made orthotics are expensive and must be made by a specially trained professional. An alternative to custom made orthotics are several brands of over-the-counter orthotics. However, there has been no research done to examine the efficacy of using an over-the-counter orthotic to correct abnormal gait mechanics. The purpose of this study was to examine the effects of an over-the counter orthotic on ankle and knee joint kinematics during running in individuals identified as excessive pronators.
