During which test does the patient extend their wrist against resistance while pronating their forearm?

The test being described is Cozen's Test, which is specifically designed to evaluate for lateral epicondylitis, commonly known as tennis elbow. In this test, the patient extends their wrist against resistance while the forearm is in a pronated position. The clinician applies resistance to the wrist extension, which places stress on the extensor muscles of the forearm, particularly the extensor carpi radialis brevis. If there is pain in the lateral elbow region during the test, it suggests the presence of lateral epicondylitis.

This testing method is particularly effective because it directly engages the muscles that are often involved in this condition, allowing for a clear assessment of potential tendon inflammation or injury. The positioning of the forearm and the action of resisting wrist extension reliably reproduce the symptoms associated with this injury, making it a valuable diagnostic tool in clinical practice.
