Overview
Pronation is a turning outward of the foot at the ankle, which allows the foot to flatten. The pronation helps to absorb some of the compressive shock forces, torque conversion, adjustment to uneven ground contours, and maintenance of balance. It is necessary to have a certain amount of pronation to disseminate the energy of the foot-strike. If there is too little or too much pronation injuries may occur. When a foot and ankle pronates to a great degree, we call it over-pronation. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is over-pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
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
People with overpronation may suffer from pain in the knees, hips, and low back. Overpronation itself does not necessarily cause any other symptoms but is a contributing factor of many foot conditions such as Plantar Facsiitis, Heel Spur Syndrome, Posterior Tibialis Tendon Rupture or Tendonitis, Hallux Valgus, Bunion Deformities, Metatarsalgia, Hallux Limitus or Hallux Rigidus, Hammer Toes, and Morton?s Neuroma.
Diagnosis
If you have flat feet or low arches, chances are you overpronate. Although not always the case, the lower your arches the greater the overpronate. Stand on a hard surface (in front of a mirror if you need to) and look at your feet, flat feet or low arches are easy to spot. If your feet look flatter than a pancake, have a look at your ankles and see if they seem collapsed or straight. If they are, you're overpronating.
Non Surgical Treatment
Supportive orthotics in the shoe is a method commonly implemented to treat many common running injuries associated with pronation. An advantage of orthotics is that they often allow the sufferer to continue to participate in athletic activity and avoid other treatment options that could be potentially costly and time consuming. Seventy-five percent of injured runners are successfully treated with the prescription of orthoses. Orthotics are the most effective treatment for symptoms that develop from unusual biomechanics within the body such as overpronation, resulting in either great improvement or complete healing of the injury in about half the cases.
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.
