What is the extension of the wrist?
Extension of the wrist refers to lifting the hand backwards from a neutral position by voluntarily contracting the muscles in the forearm increasing the angle from its corresponding position of flexion with a range of motion between sixty and seventy-five degrees.
What muscles extend and flex the wrist?
Extensor carpi radialis longus and brevis are inserted on the bases of the second and third metacarpals, extensor ulnaris on the base of the fifth metacarpal. When the wrist extensors act together, they extend the wrist. That’s an important part of the action we make when we go to grip something.
What is a wrist flexion exercise?
Wrist flexor stretch Extend your arm in front of you with your palm up. Bend your wrist, pointing your hand toward the floor. With your other hand, gently bend your wrist farther until you feel a mild to moderate stretch in your forearm. Hold for at least 15 to 30 seconds. Repeat 2 to 4 times.

- Keep your forearm in place and bend your wrist upward.
- Slowly lower the hand weight back down.
- Repeat 5 times, or as instructed.
Which 4 muscles extend the wrist?
Muscles that Extend the Wrist
- Extensor Carpi Radialis Longus.
- Extensor Carpi Radialis Brevis.
- Extensor Carpi Ulnaris.
What 5 muscles flex the wrist?
These muscles are: the flexor carpus radialis, flexor carpus ulnaris, and palmaris longus. The other three muscles, the flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus, start in the forearm and the tendons attach to phalanges (finger bones).
How can I improve my wrist flexion and extension?
Wrist flexion and extension
- Place your forearm on a table, with your hand and affected wrist extended beyond the table, palm down.

What muscles are used in wrist extension?
– Extensor Digitorum. – Extensor Carpi Radialis Longus. – Extensor Carpi Radialis Brevis. – Extensor Carpi Ulnaris. – Extensor Indicis. – Extensor Digiti Minimi. – Entensor Pollicis Longus. – Extensor Pollicis Brevis.
What muscles cause flexion of the wrist?
The two wrist flexors, acting together, produce flexion of the wrist. Acting separately, the ulnar and radial flexors contribute to ulnar abduction, and radial abduction respectively. Lying between these two main wrist flexors is a third small one, palmaris longus. It arises from the medial epicondyle, like the other two.
How do you stretch a wrist flexor?
Start with your right hand by your side with arm bent and elbow at 90 degrees
What is the normal wrist extension?
The average maximum range of wrist motion as determined by the wrist goniometer measurement was 60 degrees of extension to 78 degrees of flexion (a 138 degree arc of motion) and 21 degrees of radial deviation to 38 degrees of ulnar deviation (59 degree arc of motion).
