The Truth Related To Over-Pronation Of The Foot
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.
Causes
Pronation can occur as an overuse syndrome in active runners, where a great deal of stress is placed on ligaments and tendons that support the medial column. Obesity is another predictor for pronation and deterioration of the medial ligaments and posterior tibial tendon due to excessive stress on these tissues. Acute Trauma can also lead to over-pronation when ligaments are torn or tendon is ruptured. Once again this can lead to a collapse of the medial column. Arthritic conditions involving the knee joint when the joint is in varus (inner collapse) posture, this places the center of gravity over the ankle joint rather than the foot causing undue pressure on the inner ankle.
Symptoms
Symptoms can manifest in many different ways. Here is a list of some of the common conditions associated with over-pronation in children. Achilles Pain. Ankle pain. Arch Pain. Low back pain. Heel Pain. Knee Pain (Runner's knee and Chondromalecia of the patella) Osgood Schlatter Disease (pain below the knee) Shin Splints (pain in the front of the lower leg) Over-pronation does not necessarily mean your child has "flat feet." Even though children's arches may be relatively high when they lie down or sit, over-pronation may not be seen until your child is standing. A certain amount of pronation is normal. During normal walking or running ("gait cycle"), the heel strikes the ground and the foot rolls inward to absorb shock and adapt to the surface. This gait cycle is even more important if the running surface is uneven.
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.
Non Surgical Treatment
If you overpronate, you should talk with a foot and ankle specialist, especially if symptoms have not developed yet. Questions you may want to ask your doctor include what are the best running shoes on the market? Where can I find those shoes? If over-the-counter orthotics don?t work, how long should I wait before contacting you for custom-made orthotics? On my next visit, what type of diagnostic testing should I expect? If I limit the amount of time I spend running, will my overpronation symptoms disappear? What additional treatment options can we try?
Prevention
Wear supportive shoes. If we're talking runners you're going to fall in the camp of needing 'motion control' shoes or shoes built for 'moderate' or 'severe' pronators. There are many good brands of shoes out there. Don't just wear these running, the more often the better. Make slow changes. Sudden changes in your training will aggravate your feet more than typical. Make sure you slowly increase your running/walking distance, speed and even how often you go per week. Strengthen your feet. As part of your running/walking warm up or just as part of a nightly routine try a few simple exercises to strengthen your feet, start with just ten of each and slowly add more sets and intensity. Stand facing a mirror and practice raising your arch higher off the ground without lifting your toes. Sit with a towel under your feet, scrunch your toes and try to pull the towel in under your feet. Sitting again with feet on the ground lift your heels as high as you can, then raise and lower on to toe tips.
