Purpose

The Yergason's Test is used to test for biceps tendon pathology, such as bicipital tendonitis.

Technique

The patient should be seated or standing, with the humerus in neutral position and the elbow in 90 degrees of flexion. The patient is asked to externally rotate and supinate their arm against the manual resistance of the therapist.[1]  Yergason's Test is considered positive if pain is reproduced in the bicipital groove during the test.
