Overview
n a normal functioning ankle and foot there should be 15- to 20-degrees of ankle dorsiflexion present (leg moving forward on top of the foot; or, same as the foot bending backward toward the leg) as well as 60- to 65-degrees of first toe extension (bending backward). Foot pronation (turning downward or inward) and supination (turning upward or outward) are normal and needed movements for proper function during the gait cycle. All feet must do this and do it well in order to minimize the forces that the body has to deal with during walking or running, and also to create the lever that is needed for propulsion.
Causes
Excess stress on the inner surface of the foot can cause injury and pain in the foot and ankle. Repeated rotational forces through the shin, knee, thigh and pelvis also place additional strain on the muscles, tendons and ligaments of the lower leg.
Symptoms
If ignored, overpronation can lead to complications such as hammer toes, corns and calluses, shin splints, hallux rigidus and many more foot and lower leg problems. Hammer toes appear when the toes are placed under too much pressure and the ligaments and muscles in the toes begin to reduce in size, leading to the curvature of the toes and making them look like little hammers. Overpronators can develop hammertoes if they don?t wear an appropriate pair of shoes. Corns and calluses also appear as a result of overpronation. They form in response to excess pressure, and overpronators may find that they have excessive hard skin on the balls of the feet and inside edge of the big toe. It is the body?s way of protecting against excessive forces and friction. They can be painful.
Diagnosis
To easily get an idea of whether a person overpronates, look at the position and condition of certain structures in the feet and ankles when he/she stands still. When performing weight-bearing activities like walking or running, muscles and other soft tissue structures work to control gravity's effect and ground reaction forces to the joints. If the muscles of the leg, pelvis, and feet are working correctly, then the joints in these areas such as the knees, hips, and ankles will experience less stress. However, if the muscles and other soft tissues are not working efficiently, then structural changes and clues in the feet are visible and indicate habitual overpronation.
Non Surgical Treatment
An overpronator is a person who overpronates, meaning that when walking or running their feet tend to roll inwards to an excessive degree. Overpronation involves excessive flattening of the arches of the feet, with the roll seeing the push off take place from the inside edge of the foot and the big toe. When this happens, the muscles and ligaments in the feet are placed under excessive strain, which can lead to pain and premature fatigue of the foot. Overpronation is most commonly experienced in people who have flat feet or fallen arches.
Surgical Treatment
Depending on the severity of your condition, your surgeon may recommend one or more treatment options. Ultimately, however, it's YOUR decision as to which makes the most sense to you. There are many resources available online and elsewhere for you to research the various options and make an informed decision.
