This test is to check circulation. It looks pretty cool when it's normal. I just did it on a pt with carpal tunnel syndrome symptoms.

Google AI has a good comprehensive description of special tests for the shoulder. I always do Yergason's test incorrectly by having the pt pronate instead of supinate. Ugh. They should start prone and try to supinate against resistance.
Yergason's test is a physical examination maneuver used to assess for pathology of the long head of the biceps tendon and the transverse humeral ligament (THL) in the shoulder.
Procedure:
The patient sits with their elbow flexed at 90 degrees and their forearm pronated (palm facing down).
The examiner places one hand on the patient's forearm and the other hand on the upper part of the biceps tendon near the shoulder.
The patient is asked to supinate their forearm (turn their palm up) and externally rotate their shoulder against the examiner's resistance.
Positive Findings:
A positive Yergason's test is indicated by:
Pain in the bicipital groove (the area where the biceps tendon runs through the shoulder)
A clicking or popping sensation in the shoulder
A feeling of the biceps tendon slipping out of place
Interpretation:
A positive Yergason's test suggests that there may be an injury to the biceps tendon or the THL. This could include:
Bicipital tendinitis, SLAP (superior labrum anterior-posterior) tear, and Biceps tendon subluxation.
Additional Notes:
Yergason's test is not a definitive diagnostic test. Further imaging studies may be necessary to confirm the diagnosis.
The test should be performed carefully and with proper technique to avoid causing pain or injury.
It is important to consult with a healthcare professional for proper interpretation of the test results.

Yergason's Test
Yergason's test is a physical examination maneuver used to assess for pathology in the biceps tendon and transverse humeral ligament (THL) in the shoulder.
Purpose:
To detect biceps tendinitis or rupture
To identify a SLAP (superior labrum anterior-posterior) lesion
To assess the integrity of the THL
Procedure:
The patient sits or stands with their elbow flexed at 90 degrees and their forearm pronated.
The examiner places one hand on the patient's forearm, just above the wrist, to provide resistance.
The patient supinates their forearm (turns their palm up) while the examiner resists the movement.
The examiner palpates the biceps tendon in the bicipital groove.
Positive Findings:
Pain in the bicipital groove, A clicking or snapping sensation, and A bulge or prominence in the bicipital groove.
Interpretation:
A positive Yergason's test suggests that there may be pathology in the biceps tendon or THL. Further imaging studies, such as an ultrasound or MRI, may be necessary to confirm the diagnosis.
Limitations:
Yergason's test is not a definitive diagnostic test.
It may be false positive in patients with other shoulder conditions, such as rotator cuff tears.
It is not sensitive for detecting SLAP lesions.
Other Tests:
Speed's test, Anterior apprehension test, Hook test, and Supination-pronation test
