Yergason's Test | Rationale & Interpretation

Yorgason's test is used to detect superior labral tears, SLAP tears, and bicipital tendonitis. The test involves positioning the patient with the elbow flexed and forearm pronated, followed by resisted forearm supination. A positive result is indicated by either protrusion of the bicipital tendon or reproduction of familiar shoulder pain. The test has a sensitivity of 43% and specificity of 79%, and is often used in conjunction with Speed's test for better diagnostic accuracy.

What is the primary purpose of Yorgason's test?

• To measure muscle strength in the forearm

• To identify superior labral tears and bicipital tendonitis

• To assess the range of motion in the shoulder

• To detect fractures in the arm

In Yorgason's test, how should the patient's forearm be positioned initially?

• Supinated

• Pronated

• Neutral

• Extended

During Yorgason's test, what is the role of the physical therapist?

• To apply a supination force

• To check for shoulder dislocation

• To maintain the forearm in a pronated position

• To measure the angle of elbow flexion

What indicates a positive Yorgason's test?

• Increased range of motion in the shoulder

• Decreased muscle strength in the forearm

• Protrusion of the bicipital tendon or familiar shoulder pain

• Swelling in the elbow region

How does the specificity of Yorgason's test compare to Speed's test?

• Specificity is not a factor in these tests

• Both have the same specificity

• Speed's test has higher specificity

• Yorgason's test has higher specificity
