Overview
Normal, healthy feet pronate! Normal pronation does not need to be ?corrected?. However, some people OVER-pronate. Those people need a shoe that supports their over-pronating foot to help guide the foot and avoid injury. So, what does pronation mean exactly? Well, ?pronate? is the word used to describe the natural motion of the foot after it strikes the ground. When a person with a normally pronating foot runs, the outside part of the heel strikes the ground. As the individual shifts the body weight forward, the foot rolls inward (pronates) and the entire foot comes into contact with the ground. This allows the foot to properly support the body and absorb the impact forces. Motion continues forward and the peron pushes off (called ?toe off?) evenly from the front of the foot. Someone who OVER-pronates strikes the ground with the heel in the same way, but the foot rolls too far inward (overpronation). This causes foot and ankle strain, as it does not allow the foot and ankle to properly support the body nor to properly absorb the impact forces. As motion continues forward, they will toe-off more from the ball of her foot. Runners who overpronate are susceptible to foot, ankle and knee problems if they don't wear a shoe that properly supports the motion of their feet.
Causes
There is a relationship between biomechanics and injury that is specific to each body part. Overall though, poor mechanics will either increase the landing forces acting on the body or increase the work to be done by the muscles. Both increase the stress, which, depending on the individual and the amount of running can become excessive and cause injury.
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
You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
Non Surgical Treatment
Wear shoes with straight or semicurved lasts. Motion-control or stability shoes with firm, multidensity midsoles and external control features that limit pronation are best. Over-the-counter orthotics or arch supports can help, too. You know you are making improvements when the wear pattern on your shoes becomes more normal. Overpronation causes extra stress and tightness to the muscles, so do a little extra stretching.
Surgical Treatment
The MBA implant is small titanium device that is inserted surgically into a small opening between the bones in the hind-mid foot: the talus (ankle bone) and the calcaneus (heel bone). The implant was developed to help restore the arch by acting as a mechanical block that prevents the foot from rolling-in (pronation). In the medical literature, the success rate for relief of pain is about 65-70%. Unfortunately, about 40% of people require surgical removal of the implant due to pain.
