What does Cozen's Test primarily assess?

Cozen's Test is a clinical assessment specifically designed to evaluate the presence of lateral epicondylitis, also known as tennis elbow, which is a condition often characterized by tendinopathy of the extensor muscles of the forearm. During the test, the clinician resists active wrist extension with the elbow in extension, which places stress on the extensor tendons. If the patient experiences pain in the lateral elbow during this maneuver, it indicates a potential issue with the tendons at the origin of those muscles, confirming the presence of tendinopathy.

This targeted assessment effectively helps clinicians differentiate between various elbow pathologies and is a fundamental part of evaluating patients who present with elbow pain.
