Prospective Study of Structural and Biomechanical Factors associated with the Development of Plantar Fasciitis in Female Runners

In a retrospective study of runners with a history of plantar fasciitis, we reported that these runners exhibited significantly greater peak eversion compared to the controls (Davis et al, 2003). A trend towards greater eversion velocity was also noted. Plantar fasciitis is also often associated with limitations in ankle dorsiflexion range of motion. It is believed that this limitation may lead to a compensatory excessive pronation. This excessive pronation, noted at both the rearfoot and midfoot, leads to increased strain of the plantar fascia.
