What is pronation and supination of the forearm?
Supination and pronation are terms used to describe the up or down orientation of your hand, arm, or foot. When your palm or forearm faces up, it’s supinated. When your palm or forearm faces down, it’s pronated. Supination means that when you walk, your weight tends to be more on the outside of your foot.
Are the motions of the supination pronation?
Pronation and supination are movements that occur at the proximal radioulnar joint. The wheel like rotation of the head of the radius enables supination (palm facing upwards), and pronation (palm facing downwards).
What is supination range of motion?
The mean ROM in extension was 71.6 ± 18.6 degrees in neutral, 68.3 ± 8.4 degrees in supination, and 74.2 ± 11.1 degrees in pronation. ROM for flexion was 101.4 ± 23.7 degrees in neutral, 106.8 ± 17.8 degrees in supination, and 104.1 ± 16.9 degrees in pronation.
What movement is pronation?
Pronation describes a rotational movement of the forearm that results in the palm facing posteriorly (when in the anatomic position). Supination describes the motion of turning the palm anteriorly (Fig. 1.14).
What axis is pronation supination?
Pronation-supination, the rotation of the forearm around its longitudinal axis, is an important motion because it allows the hand to be oriented, allowing one to take food and carry it to the mouth, perform personal hygiene, and live autonomously.
What is flexion and abduction?
Abduction is the movement away from the midline of the body. Adduction is the movement toward the middle line of the body. Extension is the straightening of limbs (increase in angle) at a joint. Flexion is bending the limbs (reduction of angle) at a joint.
What is a good example of flexion?
Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. Extension is the opposite of flexion in that the angle between the bones of a joint increases.
