Foot orthotic devices are often used to treat overuse injuries, over- or under- pronation of the foot, knee pain, and other foot disorders. Clinical documentation shows the effectiveness of foot orthoses but there is little understanding of the mechanisms behind these outcomes. Existing studies of foot orthoses focus on rearfoot biomechanics, yet these devices are aimed at changing whole-foot mechanics. Additional research on the mechanical effects of orthoses is often suggested.The main goal of this study was to evaluate the effects of different foot orthotic devices on foot mechanics. In order to assess the effects foot orthoses have on the midfoot, we placed reflective markers on the participant’s lower limbs and right foot and recorded the leg mechanics as the participant walked across a 75 ft walkway.We expected directional movement patterns based on the location and type of orthotic posting or lift. It is possible that a better understanding of the effects of orthotic devices can lead to more effective treatments for patients with foot disorders.
