The mechanism of the human foot is very complex. During running, walking, jumping, this section of the limb undergoes a tremendous load every minute. Upon contact with the support, it goes through three motor phases: it is retracted or driven, it is bent or unbent, it turns outward or inward. Therefore, it is not surprising that under such loads, almost eighty percent of people have problems associated with this part of the leg.
The condition of the foot is affected by enough factors. Among them are physical activity, general health, profession, and sometimes shoes. The depreciation mechanism, the ability of this limb to become as flat as possible during exertion, was defined by the term “foot pronation”.
How to determine its degree, find out why the injury occurred? This, of course, can only be done by a doctor. However, today many people are trying to independently understand the causes of their ailments, so this article will be useful to them.
Pronation of the foot is its rotational movement inward. It helps to reduce the load from the shock, which is accompanied by contact of the limb with the support, as well as to disperse it over the entire surface.
When there is excessive pronation, the feet of a person are sore or often injured. Most often, this is observed among runners, as well as those who are in a lot of movement. Typically, in such people, shin injuries are provoked, knees and areas around the tibia hurt .
The cause of these problems is a flat contact with the support, as a result of which the arch of the foot moves inward and the toes outward. As a result, excess pressure is created on the tibia and, as a result, the effectiveness of the functioning of muscles that are stretched decreases.
The other extreme - supination or insufficient pronation of the foot - on the contrary, reduces shock absorption in contact with the supporting surface, since in this case a person relies only on its outer part.
Neither excessive pronation of the foot, nor supination are undesirable. In both cases, biomechanical failures create an excessive load in a certain part of this department. And as a result, pathologies begin to develop. For example, bone deformation or the appearance of a tissue protective layer, etc., can be observed. Pronation of the foot can also have hereditary roots.
Of course, such a violation of the motor function does not pose a threat to life. Perhaps that is why orthopedists do not sound the alarm when pronation of the foot has excessive or insufficient indicators, especially since this ailment does not require long-term medical treatment.
Most often, the doctor recommends that the patient wear special shoes that correct foot movements, as well as use insoles-arch supports. This prevents the further development of the disorder, and also indicators return to normal, as a result of which the pain decreases. Of particular importance is a special physiotherapy exercise. During it, the structures are strengthened and the pronation of the foot is normalized.
