Pronation

Pronation is the rotation of the forearm so that the palm is turned posteriorly. When pronating, the bones of the forearm (radius and ulna) cross.

Pronation occurs when the forearm rotates around its longitudinal axis from a supinated position (with the palm facing up) to a pronated position (with the palm facing down). This is a natural movement that we make in everyday life, such as turning a doorknob or turning the palm down when walking.

The opposite movement of pronation is supination - turning the forearm so that the palm faces up. Supination and pronation allow us to perform twisting movements of the hand and hold objects in the hand.

Thus, pronation plays an important role in the functioning of the upper limb, providing its mobility and participating in grasping and manipulating objects.

Pronation is the rotation of the forearm so that the palm is turned posteriorly. In this case, the bones of the forearm (radius and ulna) intersect.

Pronation is the opposite of supination. When supinated, the palm rotates forward.

Pronation is possible due to the proximal and distal radioulnar joints. In the proximal joint, the radius rotates relative to the humerus, and in the distal joint, the ulna rotates relative to the radius. These two rotations in total ensure pronation of the forearm.

Pronation and supination are important for performing many activities with the hands and fingers. For example, when pronating, it is convenient to hold a mug or turn a key in a lock.

Pronation is the rotation of the forearm so that the palm faces backward. With this action, the bones of the forearm - the radius and ulna - cross each other. This can be useful for athletes who play sports such as basketball, volleyball or tennis.

Supination is the opposite action when the palm of the hand is turned forward. This movement is also used in sports, such as golf or baseball.

Both of these techniques are important for proper forearm muscle function and improved arm strength and flexibility. However, if you do not play sports, then pronation and supination can be useful for everyday life. For example, if you write or draw, proper hand positioning will help prevent pain in your wrist and fingers.

Overall, pronation and supination are important hand techniques and can help improve your fitness and efficiency in everyday life.
