Overpronation Of The Feet

Overview

The foot and ankle complex needs to pronate to make the muscles of the hips and legs work correctly. Many muscles that originate from the pelvis attach to both the upper and lower leg. For example, the gluteus maximus and tensor fascia latae (TFL) attach to the outside of the lower leg via the iliotibial band, while the abductors attach to the outside of the femur. When the foot pronates, the whole leg rotates inward toward the center line of the body. This inward rotation pulls the attachment of the glutes, TFL and abductors away from the origin of these muscles up on the pelvis which creates tension. Similarly, the muscles of the lower leg such as the peroneals, tibialis anterior and tibialis posterior originate on the lower leg and attach to the underside of the foot. When the foot flattens out, as it does in pronation, this pulls the insertion of these muscles away from their origin on the tibia. This action also creates tension in the muscles.Pronation

Causes

There has been some speculation as to whether arch height has an effect on pronation. After conducting a study at the Rose-Hulman Institute of Technology, Maggie Boozer suggests that people with higher arches tend to pronate to a greater degree. However, the generally accepted view by professionals is that the most pronation is present in those with lower arch heights. To complicate matters, one study done by Hylton Menz at the University of Western Sydney-Macarthur suggests that the methods for measuring arch height and determining whether someone is ?flat-footed? or ?high-arched? are unreliable. He says, ?For this reason, studies investigating the relationship between static arch height motion of the rearfoot have consistently found that such a classification system is a poor predictor of dynamic rearfoot function.

Symptoms

Over-Pronation may cause pain in the heel of the foot, the foot arch, under the ball of the foot, in the ankle, knee, hip or back. The symptoms may be localized to one particular area of the foot or may be experienced in any number of combinations. Standing for long periods of time, walking and running may become difficult due to the additional stress and/or discomfort accompanied with these activities. Upon Visual Inspection, when standing the heels of the foot lean inward and one or both of the knee caps may turn inward.

Diagnosis

When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation, or more commonly known as shin splints.Pronation

Non Surgical Treatment

Orthotics are medical devices used to provide support to correct a physical abnormality. They can provide arch support when needed to remedy over-pronation, and in this particular cases the orthoses used are usually convenient shoe inserts. These can be taken in and out of shoes, and will be carefully tailored by your podiatrist to the specifics of your foot. It can take some weeks before the effects of the inserts can become truly noticeable, and in many cases your podiatrist will want to review your orthotics within a few weeks to make fine adjustments based on how well they have worked to reduce your pain.

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.
