What is Supinator syndrome?

What is Supinator syndrome?

Radial Tunnel Syndrome specifically refers to compression of the posterior interosseous nerve at the lateral intermuscular septum of arm, while Supinator Syndrome refers to compression of the posterior interosseous nerve at the arcade of Frohse, although these terms are used interchangeably.

Which muscle will Supinate the forearm?

In human anatomy, the supinator is a broad muscle in the posterior compartment of the forearm, curved around the upper third of the radius. Its function is to supinate the forearm….

Supinator muscle
Nerve Deep branch of the radial nerve
Actions Supinates forearm
Antagonist Pronator teres, pronator quadratus

Can the forearm Supinate?

Pronation and supination are a pair of unique movements possible only in the forearms and hands, allowing the human body to flip the palm either face up or face down.

How do I get rid of tendonitis in my forearm?

The best treatment is resting the sore area as much as possible and avoiding the activity that caused the injury. Rest will calm the inflammation and help relieve the pain. Icing can also be effective. Apply ice packs for 10 to 15 minutes every few hours to reduce inflammation and pain.

What muscles cause pronation of the forearm?

A tough membrane of connective tissue, called the interosseous membrane, keeps the forearm bones bonded during pronation and supination. The main muscles enabling pronation of the upper limb are pronator teres, pronator quadratus, and brachioradialis muscles.

What happens during supination of the forearm?

Forearm supination is rotation of the radius so the palm faces posteriorly (back to the anatomical position). It occurs primarily at the proximal radioulnar joint by rotation of the radial head against the radial notch of the proximal ulna, held in by the annular ligament. It is the opposite of forearm pronation.

How can I improve my forearm supination?

These activities can help develop your elbow and forearm stability:

  1. Flipping cards, cans and buttons (without setting them on the edge of a table)
  2. Playing with a Slinky®
  3. Placing stickers in your palm.
  4. Walking like a penguin.
  5. Scooping and pouring water.
  6. Doing high fives with your palm up.

Why does my Supinator muscle hurt?

The most common cause of supinator muscle pain and injury is overuse due to repetitive activities involving forearm pronation and supination (repeatedly turning the palm up and down) or constant contraction of the muscle in supination (palm up).

How do I strengthen my supinator muscles?

Supination with a dumbbell

  1. Sit in a chair holding a 2-pound dumbbell vertically in your hand with your elbow resting on your knee.
  2. Let the weight of the dumbbell help rotate the arm outward, turning the palm up.
  3. Rotate the hand back the other direction until your palm is facing downward.
  4. Repeat 20 times on each side.
