Plantar fasciitis is a repetitive microtrauma overload injury of the attachment of the plantar fascia at the inferior aspect of the calcaneus. The diagnosis of plantar fasciitis is common among athletes in many sports, primarily those sports that involve running. Common treatments for plantar fasciitis, including ice, stretching, ultrasound, and shoe inserts are helpful in reducing the symptoms. However, recurrence of the problem is common. By understanding the potential biomechanical causes of this disorder it may be possible to correct the anatomical and biomechanical variables that cause plantar fasciitis and reduce the rate of recurrence as well as speed the rehabilitation process. It may also be possible to identify predisposing maladaptations that can be corrected, therefore, preventing the initial occurrence of plantar fasciitis.
