What action does the patient perform during Cozen's Test?

Cozen's Test is specifically used to assess for lateral epicondylitis, commonly known as tennis elbow. During this test, the patient is asked to perform wrist extension against resistance. This action places tension on the extensor muscles of the forearm as well as the extensor tendons that attach to the lateral epicondyle of the humerus.

When the patient extends their wrist while the examiner provides resistance, any pain experienced in the area of the lateral epicondyle suggests a positive test result, indicating a potential injury to the extensor tendons. This is crucial for diagnosing conditions related to overuse of the wrist extensors, which is characteristic of lateral epicondylitis.
