What symptom indicates a positive result for the Cozen's Test?

The Cozen's Test is specifically designed to assess for lateral epicondylitis, commonly known as tennis elbow. A positive result for this test is indicated by experiencing pain in the lateral epicondyle when resistance is applied during wrist extension with the forearm in a pronated position.

When a patient exhibits pain in the lateral epicondyle during the Cozen's Test, it suggests that the common extensor tendon, particularly the extensor carpi radialis brevis, is likely inflamed or degenerating, which is characteristic of lateral epicondylitis. This pain is typically a result of repetitive stress or overuse of the extensor muscles of the forearm.

Other options may reflect various conditions or symptoms unrelated to the purpose of the Cozen's Test, thereby not fitting the significance of a positive test result. Weakness in wrist extension, for example, may suggest more generalized weakness or a different pathology affecting the muscles innervated by the radial nerve but does not specifically confirm lateral epicondylitis. Pain in the medial epicondyle is more indicative of medial epicondylitis or golfer's elbow, while tingling in the forearm could suggest nerve involvement or irritation, which is separate from the focus of this particular test.
