Overpronation Of The Foot Discomfort

Overview

When standing, pronation occurs as the foot rolls inwards and the arch of the foot flattens. Pronation is a normal part of the gait cycle which helps to provide shock absorption at the foot. The opposite movement to pronation is supination. This is also a normal part of the gait cycle just after the heel strike however over-supination is also not good.Pronation

Causes

There are many causes of flat feet. Obesity, pregnancy or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Often people with flat feet do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.

Symptoms

Due to the laxity of the soft tissue structures of the foot, and the fact that the joints are not held together properly, the bones of the feet shift. When this occurs, the muscles that attach to these bones must also shift, or twist, in order to attach to these bones. The strongest and most important muscles that attach to our foot bones come from our lower leg. So, as these muscles course down the leg and across the ankle, they must twist to maintain their proper attachments in the foot. This twisting of these muscles will cause shin splints, Achilles Tendonitis, generalized tendonitis, fatigue, muscle aches and pains, cramps, ankle sprains, and loss of muscular efficiency (reducing walking and running speed and endurance). The problems we see in the feet, which are due to over-pronation include bunions, heel spurs, plantar fasciitis, fallen and painful arches, hammertoes, metatarsalgia (ball of foot pain), and calluses.

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.Foot Pronation

Non Surgical Treatment

Not all over pronation is treated. Although, when it appears to be a causitive factor that is contributing to pain,or development of structural deformities, there are various degrees of treatment.In some cases specific shoes may be all that is required. In other cases, paddings or strapping, are prescribed and where necessary orthotic therapy. A podiatric assesment would be advised to asses this.

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.
