Plantar fasciitis is a common overuse injury found in runners. The plantar fascia, which is responsible for maintaining the integrity of the longitudinal arch, becomes irritated, inflamed or torn by repetitive stresses placed upon it. Commonly cited predisposers of plantar fasciitis are excessive pronation, a flat or cavus foot, tight Achilles tendon, type of training shoes worn, and errors in the training routine. Once the plantar fascia becomes irritated a myriad of conservative measures may be used, including everything from rest, ice and elevation to steroid injections and, if all else fails, surgery. In most cases conservative treatment of one kind or another will alleviate the symptoms of plantar fasciitis. However, it is essential to determine and correct the cause of the problem in order for the runner to resume normal activity levels. Controlling anatomical/biomechanical inefficiencies of the feet, stretching and strengthening exercises for the lower extremity, proper training shoes, and reasonable training routines will alleviate the symptoms of plantar fasciitis in a large percentage of sufferers. To prevent this injury, runners should be aware of the potential overuse injury and take precautionary measures, e.g. seek a biomechanical/anatomical evaluation from a qualified practitioner. The practitioner can then offer suggestions as to the specific steps the runner should follow to prevent the injury condition.
