Overpronation results in incorrect loading of the foot.

In medicine, the term pronation describes the movement of an extremity. The word pronation comes from Latin and means something like "lean forward" or "turn forward". The opposite movement to pronation is supination.

There is pronation of the hand or forearm and pronation of the foot. Both are presented in the following text.

Pronation of the forearm

In the Pronation of the forearm play the spoke (radius) and the Cubit (Ulna) a role. In the pronation movement of the forearm the arm turns "inwards". With an outstretched arm with the palm facing up, the arm is rotated so that the Palm down shows and the Thumb towards the body. The hand and forearm are rotated during this movement. This comes from the Movement of the forearm muscles which arise or start at the ulna and radius. The joints involved are called Articulatio radioulnaris proximalis and Articulatio radioulnaris distalis. The following muscles are involved in the pronation of the forearm:

  • Pronator teres muscle
  • Pronator quadratus muscle
  • Brachioradialis muscle.

Pronation of the foot

In the Pronation of the foot will the outer side of the foot up moves and the middle foot side down. The heel is not moved. The foot so kinks inwards from. The muscles responsible are called:

  • Peroneus longus muscle
  • Peroneus brevis muscle
  • Extensor digitorum longus muscle.

The first two mentioned the Major muscles for this movement are. If the feet are incorrectly positioned, it can lead to Over- or underpronation come. This can lead to a Incorrect load on the foot which in turn is harmful to tendons and Muscles can be. Therefore, there are also different shoes for running for the different foot positions. The causes of foot deformity are mostly innate, by Obesity acquired or caused by excessive fatigue.

To yourself Supination and pronation better to remember there two donkey bridges:
"In the Supination lies the hand in the form of a bowl for Suppe and the Pernation lies in the hand as with Brocutting ".
