Plantar fasciitis. Mechanics and pathomechanics of treatment.

An excessive amount and/or a prolonged duration of pronation is the most common mechanical cause of structural strain resulting in plantar fasciitis. Temporary relief of pain can be achieved by customary antiinflammatory drugs or therapy; long-term relief is achieved by adequate remedy of the aggravating pronation factors. A semirigid, custom-molded orthosis reduces excessive plantar fascial strain by supporting the first metatarsal bone and by controlling calcaneal position when in conjunction with a firm posterior counter shoe. A clinical environment with physician and orthotist together allows ideal evaluation and treatment of patients.
