Purpose: To determine the presence of a lateral epicondylalgia.
Test Position: Standing.
Performing the Test: Palpate the lateral epicondyle while passively pronating the forearm, flexing the wrist and extending the elbow. A positive test is reproduction of lateral elbow pain.
Diagnostic Accuracy: Unknown.
Importance of Test: According to Neumann, the common proximal attachment site of the wrist extensors is on or near the lateral epicondyle of the humerus and dorsal border of the ulna. The distal attachments of the extensor carpi radialis longus and brevis are the 2nd and 3rd metacarpals respectively. These muscles are responsible for wrist extension and radial deviation. The extensor carpi ulnaris attaches to the 5th metacarpal and is responsible for wrist extension and ulnar deviation. With tendinopathy, any stretch or contraction of the tissues can potentially reproduce pain. The starting position of the test (elbow flexion, wrist extension, radial deviation, and pronation) places the muscles in a shortened position. The combined motions of elbow extension, wrist flexion, pronation, and palpation of the origin of the muscles reproduce the patient's symptoms, by placing a stretch on the tissues.
Note: these tests should only be used by properly trained health care practitioners
