Yergason’s test

This is a clinical exam used to evaluate for inflammation of the biceps tendon (called biceps tendonitis). To perform the test, the patient’s elbow is bent to 90 degrees with the thumb up. The examiner grasps the wrist, and resists the patient from trying to turn the palm up and bend the elbow further (at the same time). Pain with this maneuver indicates biceps tendonitis.
