A positive Cozen's test indicates the presence of lateral elbow pain. This test is commonly used to assess for tennis elbow, also known as lateral epicondylitis or epicondylalgia.
Understanding the Cozen's Test
The Cozen's test involves evaluating the isometric resistance of the wrist extensor muscles. The patient extends their elbow fully, pronates their forearm, and extends their wrist. The examiner then provides resistance against the wrist extension. A positive result is identified by pain experienced on the lateral aspect (outside) of the elbow joint.
Several sources confirm this interpretation:
- Physiopedia states that a positive Cozen's test is indicated by pain elicited on the lateral epicondyle.
- Physiotutors confirms that it's a common orthopedic test for tennis elbow.
- Multiple research articles and medical websites consistently report that pain over the lateral elbow indicates a positive test result. These references often note the test's use in diagnosing lateral epicondylitis.
Important Note: While the Cozen's test is a commonly used assessment, it's crucial to remember that it's not a definitive diagnostic tool on its own. A positive test suggests the possibility of lateral epicondylitis, but further evaluation may be necessary for accurate diagnosis. The test's diagnostic accuracy is debated, with some studies showing false positives.
Examples of Positive Test Results:
- The patient reports sharp pain on the outer side of their elbow when resistance is applied.
- The patient experiences a significant increase in pre-existing lateral elbow pain during the test.
