P&P #16. Abnormal Foot Pronation or Supination May Be Misidentified as the Primary Causes of Lower Extremity Running Injuries.
Many authorities label overpronation or oversupination etc as the major causes of many running injuries to the leg. However, running and all forms of gait, for that matter, involve the action of several interacting joints, so that it is impossible during dynamic gait to have pure pronation of the foot.
Depending on the runner's particular style, the action rather may be described as inversion or eversion (where these terms are NOT synonyms for pronation or supination!). Even this may be a serious oversimplification, since the athlete may also exhibit varus or valgus, plus other idiosyncrasies of joint action of the hips, toes and other joints.
Do you consider it useful and informative to label leg injuries as a simple result of overpronation or oversupination?
