Podiatric Biomechanics is the 'foot function' approach used in the treatment of lower limb musculoskeletal dysfunction. Biomechanics is concerned with understanding the movement and forces applied to the foot and lower extremities of the human body. Biomechanics practitioners are concerned with trying to modify those forces to spread some load and reduce some forces and pressures that may be applied to the foot at any given moment in order to improve a person's gait.
