The extensor carpi radialis brevis may be involved as well as the supinator muscle, at least electrodiagnostically ( … He has "wrist drop" (inability to extend the wrist), lack of extension at the elbow, and although abduction can be initiated, it cannot be completed. In order to increase the stretch apply light pressure at the end of range of motion and hold for 2 seconds. Wrist abduction occurs through the actions of _____ muscles. Rotation of the thumb and little finger allows for opposition. Correlations between the two tests were low for wrist, knee, ankle, and hip extension; moderate for elbow flexion, neck flexion and hip abduction; and good for shoulder abduction. The flexor carpi radialis arises adjacent to the pronator teres (an elbow muscle), crosses the elbow and wrist, and attaches to the base of the second hand bone. Extension. Flexor Digitorum Profundis. (Refer to Animated Figure 8-3.) Active Isolated Stretching: wrist adduction and abduction. Flexor Pollicis Longus. Flexor carpi radialis: This wrist muscle originates on the medial epicondyle of the humerus and inserts on the base of the second and third metacarpals. It's innervated by the median nerve and flexes and abducts the hand at the wrist. Wrist extension. Biceps. Have patient flex elbow slightly then apply resistance just proximal to wrist in direction of elbow flexion. The hand’s complex anatomy consists of 27 bones, 27 joints, 34 muscles, over 100 ligaments and tendons, numerous blood vessels, nerves, and soft tissue. Abduction/Adduction. EXTENSION. The posterior region of the forearm hosts the various muscles which are responsible for extension of the hand. Lying medially to the brachioradialis muscle is the long and tapered extensor muscle named carpi radialis longus.

As the contralateral arm is extended and beginning wrist flexion, the arm along the body begins slight horizontal abduction and shoulder extension, which leads into full shoulder flexion and slight horizontal adduction as the arm comes back into contact with the water. Wrist flexors. Nerves and Blood Vessels. Common Issues: Overactive/Short Wrist Extensors: The wrist extensors can become overactive and short from overuse caused by activities involving repetitive wrist extension and wrist abduction. This action is minimal for extension but will often become much greater in flexion. The muscles allow a range of movements such as flexion, extension, abduction or radial deviation, and adduction or ulnar deviation. The ulna is not part of the Flexion, extension/hyperextension, adduction, abduction. Muscles of the forearm that act on the wrist and hand are referred to as extrinsic muscles, or external to the hand. The posterior muscles of the wrist are generally used for extension but in a few exceptions carry out an additional action. Bend or flex the elbow. Explain this observation in terms of the muscles' lines of application. Rotation of the thumb and little finger allows for opposition. Extensor muscles also help to supinate and abduct the wrist.
