Foot Mechanics and Structural Symmetry

Foot biomechanics add an interesting dimension to structural symmetry and leg length. People experience leg length changes not because it is a “normal” condition as many are lead to believe. Leg length changes may be caused by hip dysplasia or fractures of the femur when the growth plate is open. But most commonly, leg length change occurs when lifting improperly in conjunction with poor posture creating extreme stress on the S-I joint and the myofascial system. This can be the same area that contributes to sciatica. Foot mechanics that cause a flat foot, “pes planus” or a high arch “pes cavus” can have problematic influence on the knee and hip. A foot that is flat can produce stress on the knee that causes muscle tension. Since a large majority of the muscles that cross the knee originates in the hip, the effect of a flat foot will be magnified at the knee and hip. The orthotics that we issue are custom made to address your unique foot condition. They are a personally customized orthotic impression to enable support and control in four areas; the heel, arch, great toe and toe box. In this manner the foot can become a positive component in supporting the lower limb and contribute to the optimal function of the lower limb, knee, hip and lower back.
