Over-Pronation

Overview

Pes planus is the medical term for flat feet. It comes from Latin, Pes = foot and Planus = plain, level ground. Very few people suffer from this condition, as a true flat foot is very rare. Less than 5% of the population has flat feet. The majority of the population, however, has fallen arches (an estimated 60-70% of the population) known in the medical profession as ?excess pronation? or over-pronation. Over-pronation means the foot and ankle tend to roll inwards and the arch collapses with weight-bearing. This is a quite a destructive position for the foot to function in and may cause a wide variety of foot, leg and lower back conditions.Foot Pronation

Causes

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.

Symptoms

When standing, your heels lean inward. When standing, one or both of your knee caps turn inward. Conditions such as a flat feet or bunions may occur. You develop knee pain when you are active or involved in athletics. The knee pain slowly goes away when you rest. You abnormally wear out the soles and heels of your shoes very quickly.

Diagnosis

The best way to discover whether you have a normal gait, or if you overpronate, is to visit a specialty run shop, an exercise physiologist, a podiatrist or a physical therapist who specializes in working with athletes. A professional can analyze your gait, by watching you either walk or run, preferably on a treadmill. Some facilities can videotape your gait, then analyze the movement of your feet in slow-motion. Another (and less costly) way is to look at the bottom of an older pair of run shoes. Check the wear pattern. A person with a normal gait will generally see wear evenly across the heel and front of the shoe. A person who overpronates will likely see more wear on the OUTside of the heel and more wear on the INside of the forefoot (at the ball). A person who supinates will see wear all along the outer edges of the shoe. You can also learn about your gait by looking at your arches. Look at the shape your wet feet leave on a piece of paper or a flat walking surface.Over-Pronation

Non Surgical Treatment

Pronation and supination are bio-mechanical problems, and are best treated and prevented with orthotic inserts. But before you run out to buy orthotics it makes sense to get the right advice on footwear, and the best advice I can give you, is to go and see a qualified podiatrist for a complete foot-strike and running gait analysis. They will be able to tell you if there are any concerns regarding the way your running gait is functioning. After your running gait has been analysed, have your podiatrist, or competent sports footwear sales person recommend a number of shoes that suit your requirements. Good quality footwear will go a long way in helping to prevent pronation and supination. And, if needed, invest in a pair of orthotic inserts to further prevent excessive pronation or supination.

Prevention

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 function.
