The Treatment And Cause Of Overpronation

Overview

Overpronation still continues to be misused and misunderstood. For example, there was a study that got a lot of recent mileage in the mainstream media and the blogosphere that claimed to show that foot pronation was not associated with injury risk. It was intriguing following comments on the study in mainstream media and in social media, especially the parroting of the press release without any critical appraisal. The study actually eliminated the ?overpronators? that were probably at high risk from the study then found that ?overpronation? was not a risk factor. What is more intriguing was that there was another study from around the same time that found the exact opposite. Clearly, the data on ?overpronation? and risk for injury in runners is mixed, so we need to rely on the more formal systematic reviews and meta-analyses of all the data. The most recent one of those concluded that ?overpronation? is just a small risk factor for running injury risk, but it is still statistically significant.Over-Pronation

Causes

Over-pronation may happen because the tissue that attaches to your foot bones is loose. You may be born with this problem or it may result from injuries or overuse, like from too much running.

Symptoms

Common conditions seen with overpronation include heel pain or plantar fasciitis, achilles tendonopathy, hallus valgus and or bunions, patellofemoral pain syndrome, Iliotibial band pain syndrome, low back pain, shin splints, stress fractures in the foot or lower leg.

Diagnosis

To easily get an idea of whether a person overpronates, look at the position and condition of certain structures in the feet and ankles when he/she stands still. When performing weight-bearing activities like walking or running, muscles and other soft tissue structures work to control gravity's effect and ground reaction forces to the joints. If the muscles of the leg, pelvis, and feet are working correctly, then the joints in these areas such as the knees, hips, and ankles will experience less stress. However, if the muscles and other soft tissues are not working efficiently, then structural changes and clues in the feet are visible and indicate habitual overpronation.Foot Pronation

Non Surgical Treatment

Anti-Pronation Insoles provide a unique foot support system that aligns the lower body. The major cause of foot and leg pain is over pronation (rolling over of the feet) which causes excessive pressure on the muscles, ligaments and bones of the lower body. Running insoles treat the underlying cause of over pronation and prevent future occurrences of the associated foot or leg condition. A project conducted at the NIKE Sport Research Laboratory studied the effects of orthotics on rear foot movement in running. Nine well-trained runners who wore orthotics were chosen as subjects. The results of the study indicated that orthotics reduced rear foot movement by roughly one degree or approximately nine percent of the amount found in runners not using orthotics. The average reduction of the maximum velocity of pronation was fifteen percent. Thus this study indicates that orthotics and insoles control over pronation which will treat and prevent many sporting injuries.

Surgical Treatment

Subtalar Arthroereisis. Primary benefit is that yje surgery is minimally invasive and fully reversible. the primary risk is a high chance of device displacement, generally not tolerated in adults.

An implant is pushed into the foot to block the excessive motion of the ankle bone. Generally only used in pediatric patients and in combination with other procedures, such as tendon lengthening. Reported removal rates vary from 38% - 100%, depending on manufacturer.
