Supination (or under-pronation) is the opposite of pronation and refers to the outward roll of the foot during normal motion. A natural amount of supination occurs during the push-off phase of the running gait as the heel lifts off the ground and the forefoot and toes are used to propel the body forward.
Is pronation more powerful than supination?
The insertion of the biceps on the radial tuberosity gives it plenty of power to rotate the radius, especially when the elbow is flexed. … Because of the great strength which biceps contributes, supination is a more powerful action than pronation.
What do the supinator and pronator muscles do?
The main muscles enabling pronation of the upper limb are pronator teres, pronator quadratus, and brachioradialis muscles. Supination is mainly facilitated by supinator and biceps brachii muscles. Injury to the upper limb can damage any of the nerves or muscles involved in pronation and supination.
What is an example of supination?
Supination is the movement in which a person turns their hand, wrist, and forearm upward. Turning your hand over to receive money is an example of supination.
What is supinator syndrome?
In supinator syndrome there is compression damage to one of the branches of the radial nerve in the elbow area. Patients suffer from pain in the posterior side of the forearm, which intensifies if pressure is applied to the outside of the elbow. In advanced stages, the muscles are impaired in function.
Can supination be corrected?

What causes pronation?
Wear and Tear. Strain, overuse, and wear on the muscles, ligaments, and plantar fascia (arch) of the foot can cause the foot to flatten too much–and roll inward excessively–as it strikes the ground, leading to overpronation.
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).
Is Overpronation really a problem?
Overpronation puts people at an increased risk of developing specific injuries. This is because it disrupts the body’s natural alignment and causes increased impact when the foot strikes the ground. Athletes with overpronation, particularly runners, see an increased likelihood of developing overuse injuries.
How do I know if I have Underpronation or Overpronation?
Look at the soles of your shoes and identify the areas where the wear is most pronounced. If the outer part of your sole is the most worn out, then you are a supinator, like about 10% of the population. If it is the inner part of your sole that is the most worn out, then you are a pronator, like 45% of the population.

What is Wartenberg’s syndrome?
Introduction. Wartenberg’s Syndrome is described as the entrapment of the superficial branch of the radial nerve with only sensory manifestations and no motor deficits. In this condition, the patient reports pain over the distal radial forearm associated with paresthesia over the dorsal radial hand.
How is Supinator syndrome treated?
First-line treatment is conservative management, including rest, work modification, NSAIDs for pain control, and physical therapy. Surgical intervention is rarely required, although nerve decompression may be necessary in some cases.
What is Saturday night palsy?
