Cozen’s Test is an elbow examination procedure that is used to identify lateral epicondylitis or “tennis elbow.” This test is also called resisted wrist extension test or resistive tennis elbow test.


Patient should be awake and cooperative to perform the Cozen’s Test.

  1. Patient should be seated while the test is being done.
  2. Examiner tells the patient to fully flex his elbow with the forearm pronated and the wrist extended. This is similar to a “waiter position.”
  3. The examiner puts pressure over the direction of the elbow extension and wrist flexion as he uses his other hand to stabilize the patient’s elbow.
  4. The examiner watches for signs of pain or discomfort or for any sign of weakness while the procedure is done.

Patient assumes the “waiter position” as the examiner applies pressure over the elbow and the wrist.


Positive Cozen’s Test

A positive Cozen’s Test is when there is pain or weakness. This sign could indicate the presence of lateral epicondylitis.

Clinical Notes

Patients have different ways to describe pain but in Cozen’s Test, pain is said to be sharp and shooting. Pain may also be elicited by palpation of the radial nerve and the common extensor tendon.
