Pronation is the term used to describe a natural movement of the foot when walking. When the gait is normal, the heel strikes the ground first. As weight is transferred forward, the arch of the foot
flattens and the foot rolls slightly inwards. Body weight is then placed on the ball of the foot and toes, and the foot straightens and turns outwards as the toes push off. Overpronation occurs when
the foot rolls inward too far. This causes all the muscles and tendons of the lower leg to twist excessively. Regular overpronation is believed to contribute to the development of many knee, lower
leg and foot injuries such as heel spurs, plantar fasciitis, tendinitis and bunions. It is thought that as much as 60% of the population may overpronate.
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.
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.
Look at the wear on your shoes and especially running trainers; if you overpronate it's likely the inside of your shoe will be worn down (or seem crushed if they're soft shoes) from the extra
Non Surgical Treatment
Personal orthotics can be prescribed via your healthcare professional. If finances or insurance are issues, similar and often better options can be purchased online for overpronation. The right
walking shoes are also essential. Most shoes cater to neutral foot gaits, unless they specifically state otherwise. That won?t help you if your foot rolls inward. In order to correct the issue, you
need shoes with stability or motion control abilities, low heels, deep heel cups, and good arch support.
Many of the prevention methods for overpronation-orthotics, for example-can be used interchangeably with treatment methods. If the overpronation is severe, you should seek medical attention from a
podiatrist who can cast you for custom-made orthotics. Custom-made orthotics are more expensive, but they last longer and provide support, stability, and balance for the entire foot. You can also
talk with a shoe specialist about running shoes that offer extra medial support and firm heel counters. Proper shoes can improve symptoms quickly and prevent them from recurring. Surgery can
sometimes help cure and prevent this problem if you suffer from inherited or acquired pes planus deformity. Surgery typically involves stabilizing the bones to improve the foot?s support and
