The Yergason’s Test is used to test for biceps tendon pathologies, such as bicipital tendonitis and an unstable superior labral anterior-posterior (SLAP) lesion.
A common variation of the test is described when the patient moves the shoulder in external rotation while simultaneously moving the forearm to the supine position also against resistance. It is a complex movement and the patient is fortified to perform it without resistance first to obtain an effective reply when resistance is added.
Palpate the biceps tendon as it passes finished the bicipital groove to identify any injuries, abnormal lumps, or abnormal movement (i.e., biceps tendon) in the affected area.
This is a difficult test to do for an accurate diagnosis. False-positive results may be the result of a rotator cuff tear, while pain in the higher glenohumeral region is a feeble predictor of a SLAP tear.
Performing the yergason’s test
The examiner stands next to the patient on the test side. The patient’s elbow is flexed to 90 degrees and rests in a prone position. The patient is instructed to supinate the forearm and externally rotate the shoulder while the examiner applies a pronation force, resisting the supination. While performing the test, the examiner palpates the biceps tendon in the bicipital groove. The test is considered positive if you have localized pain in the bicipital groove or a snapping biceps tendon outside the bicipital groove.
Sensitivity: 74; Specificity: 58; +LR: 1.76; -LR: .45
Importance of the yergason’s test
According to our clinical experiences, many patients with subacromial impingement syndrome often have a subsequent worsening of the biceps tendency. It is important to test the irritability of the biceps tendon when evaluating a shoulder. Both the speed test and the Yergagon test attempt to discriminate between pathologies of the bicipital tendon.
The patient’s elbow is flexed and the forearm is prone. The examiner holds your arm by the wrist. The patient actively supines against resistance.
A localized pain in the area of the bicipital groove suggests pathology in the long head of the biceps in its sheath.
To assess the stability of the biceps tendon in the bicipital groove by the transverse ligament of the humerus or biceps tendonitis.
The positive finding is pain and the sensation of the biceps coming out of the groove.
