What is flexion and extension of the wrist?
What is flexion and extension of the wrist?
When your wrist flexion is normal, that means that the muscles, bones, and tendons that make up your wrist are working as they should. Flexion is the opposite of extension, which is moving your hand backward, so that your palm is facing up. Extension is also part of normal wrist range of motion.
What are the 4 ranges of motion of the wrist?
Movement at both the radiocarpal and midcarpal joints is necessary to achieve the full range of motion (ROM) of the wrist, which has been classified as a condyloid joint with 2 degrees of freedom. Motions present at the wrist include flexion, extension, abduction (radial deviation), and adduction (ulnar deviation).
What axis does wrist flexion and extension occur?
sagittal plane
The wrist complex (radiocarpal and midcarpal joints) permits flexion–extension in the sagittal plane around a medial–lateral axis and radial–ulnar deviation in the frontal plane around an anterior–posterior axis. Both joints contribute to these motions.
What are the wrist extensors?
The wrist extensors are a group of nine individual muscles on the back of the forearm that act on the wrist and fingers. Collectively, their primary function is wrist extension, though they also help carry out other movements of the wrist and fingers.
What is normal wrist flexion?
Results: Normal values for wrist ROM are 73 degrees of flexion, 71 degrees of extension, 19 degrees of radial deviation, 33 degrees of ulnar deviation, 140 degrees of supination, and 60 degrees of pronation.
Where does wrist flexion occur?
All the movements of the wrist joint are performed by the muscles of the forearm. Flexion is mainly produced by the flexor carpi ulnaris and flexor carpi radialis, with the support from the flexor digitorum superficialis.
What plane is flexion and extension?
Sagittal
Summary
| Plane | Description |
|---|---|
| Sagittal / Antero-posterior | Bisects the body from front to back, dividing it into left and right halves. Flexion and Extension movements usually occur in this plane. |
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).
What is the normal range of motion for the wrist?
The wrist joint was found to have three degrees of freedom (flexion-extension, radioulnar deviation, and rotation). The normal functional range of wrist motion is 5 degrees of flexion, 30 degrees of extension, 10 degrees of radial deviation, and 15 degrees of ulnar deviation.
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.
Wrist flexion is the action of bending your hand down at the wrist, so that your palm faces in toward your arm. It’s part of the normal range of motion of your wrist. When your wrist flexion is normal, that means that the muscles, bones, and tendons that make up your wrist are working as they should.
