Overpronation is a term that gets thrown around a lot by psuedo-experts and there is so much written online about it, that it can get very confusing to determine what is legitimate and what is not. Pronation is a normal motion of the foot that occurs when the ankle rolls inwards and the arch collapses. This is normal. Its not something evil. Overpronation is assumed to be when there is too much of it. There certainly is debate as to just how much is too much, as some people have large amounts and have no problems, other have small amounts and do have problems. It all comes down to individual differences and how much force is needed to stop the foot moving. The greater the force, regardless of the amounts of pronation, the more likely it is to be a problem. Some still like to debate if it is a problem or not. Some studies have shown that its not a problem and other studies have shown it is. If the data from all these studies are pooled, then the conclusion was that, yes, overpronation is a problem that was statistically significant, but it was only a small risk factor for problems. An associated finding of overpronation during a gait analysis is an abductory twist.
There may be several possible causes of over pronation. The condition may begin as early as birth. However, there are several more common explanations for the condition. First, wear and tear on the muscles throughout the foot, either from aging or repetitive strain, causes the muscles to weaken, thereby causing the foot to turn excessively inward. Also, standing or walking on high heels for an extended period of time also places strain and pressure on the foot which can weaken the tissue. Lastly, shoes play a very common factor in the development of over pronation. Shoes that fail to provide adequate support through the arch commonly lead to over pronation.
If you overpronate, your symptoms may include discomfort in the arch and sole of foot. Your foot may appear to turn outward at the ankle. Your shoes wear down faster on the medial (inner) side of your shoes. Pain in ankle, shins, knees, or hips, especially when walking or running.Unfortunately, overpronation can lead to additional problems with your feet, ankles, and knees. Runners in particular find that overpronation can lead to shin splints, tarsal tunnel syndrome, plantar fasciitis, compartment syndrome, achilles tendonitis, bunions (hallux valgus) patello femoral pain syndrome, heel spurs, metatarsalgia. You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat feet can also be traumatic in nature and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
Do the wet foot test. Get your feet wet and walk along a paved surface or sand and look at the footprints you leave. If you have neutral feet you will see a print of the heel with a thin strip connecting to your forefoot, but if you're overpronating your foot print will look a bit like a giant blob with toes.
Non Surgical Treatment
Side Step with Opposite Reach. This exercise is designed to load the "bungee cord system" of the gluteal muscle and its opposite, latissimus dorsi muscle to keep the foot from overpronating. Because the opposite arm swings across the front leg when walking, this exercise creates tension in the muscles all the way from the front foot, across the back of the hips and back, to the fingers of the opposite hand. Movement Directions. Stand with left foot on top of the dome of the BT. (Note: For added balance, the right foot can tap on the ground, if needed). Reach right leg out to the side of the BT, and tap the ground while squatting down on the left side and reaching right arm across the left knee. Push down with left big toe while squatting. This activates the arch of the left foot and strengthens all the stabilizing muscles on the left side of the lower body. Return to starting position. Perform 8 to 10 repetitions on each leg.
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
