Background

Foot pronation during the early stance phase of gait allows the foot to accommodate to the irregularities of the ground surface and to attenuate ground reaction forces. Pronation involves multiple joint movements at the rearfoot and midfoot, and may influence more proximal segments leading to internal rotation of the lower limb and hip.1

Excessive foot pronation may promote non-physiological stresses on bone and musculo-tendinous structures of the lower limb and subsequent injury.2 Several overuse injuries have been attributed to excessive foot pronation. Injuries might occur at the foot level, such as plantar fasciitis, as well as at …
