What does Cozen's Test detect?

Cozen's Test is specifically designed to evaluate for lateral epicondylitis, commonly known as "tennis elbow." This condition is characterized by pain and tenderness around the outside of the elbow due to overuse of the forearm muscles and tendons, particularly the extensor group.

During Cozen's Test, the patient is asked to extend the wrist while the therapist applies resistance. A positive result, indicated by pain at the lateral epicondyle during this maneuver, suggests inflammation or injury to the common extensor tendon, which is involved in lateral epicondylitis.

Understanding this context highlights why the answer pointing to lateral epicondylitis is the most relevant and accurate regarding what Cozen's Test detects.
