Supination of the radioulnar joint can move from 0 degrees neutral to approximately 80-90 degrees where pronation of the radioulnar joint can move from 0 degrees neutral to approximately 70-90 degrees. [5] Supination (palms facing up) vs. pronation (palms facing down).
This movement is known as a pronation/supination test of the upper extremity. A simpler method using this same concept is to ask the patient to demonstrate the movement of trying a doorknob or screwing in a light bulb.
The forearm contains two bones: the radius and the ulna. These bones are attached to each other both at the proximal, or elbow, end and also at the distal, or wrist, end. Among other movements, the forearm is capable of pronation and supination, which is to say rotation about the long axis of the forearm.
The brachioradialis reflex (also known as supinator reflex) is observed during a neurological exam by striking the brachioradialis tendon (at its insertion at the base of the wrist into the radial styloid process (radial side of wrist around 4 inches (102 mm) proximal to base of thumb)) directly with a reflex hammer when the patient's arm is relaxing.
The most important joint connecting the wrist to the metacarpus, osteoarthritis of the TMC is a severely disabling condition; up to twenty times more common among elderly women than in average. [1] Pronation-supination of the first metacarpal is especially important for the action of opposition. [1]
The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. [1] [2] It is also capable of both pronation and supination, depending on the position of the forearm. [2]
Rotational wristlock by an Aikido instructor. A rotational wristlock (in budo referred to as kote hineri, and in Aikido referred to as a type of sankyō, 三教, "third teaching") [5] [6] is a very common type of wristlock, and involves forced supination or pronation of the wrist, and is typically applied by grabbing and twisting the hand.
Pronator teres syndrome is one cause of wrist pain. It is a type of neurogenic pain. It is a type of neurogenic pain. Patients with the pronator teres syndrome have numbness in median nerve distribution with repetitive pronation/supination of the forearm, not flexion and extension of the elbow
