What does a positive Cozen's Test indicate?

A positive Cozen's Test specifically indicates the presence of tendinopathy, particularly lateral epicondylitis, commonly known as tennis elbow. This test is designed to assess the integrity and function of the wrist extensors, particularly the extensor carpi radialis brevis. When the examiner applies resistance while the patient extends their wrist, pain or discomfort at the lateral epicondyle suggests irritation or inflammation of the tendons in that region.

Understanding this test is crucial for evaluating conditions related to chronic overuse of the forearm muscles, which can lead to tendinopathy. By identifying these issues early through diagnostic tests like Cozen's, clinicians can effectively manage and treat conditions to prevent further complications or deterioration of function.
