What is Snap Test?
The snap test tests examine for subluxation (partial dislocation) of the long head of the biceps or biceps brachii tendon.
The procedure of performing the Snap Test ShoulderÂ
- The examiner first palpates the bicipital groove with the middle and index finger of one (left) hand.
- Now with the other (right) hand, the examiner abducts the arm 80 to 90 degrees and then flexes the elbow at 90 degrees.
- After that, the examiner grasps the wrist of the patient’s arm, and then the examiner passively rotates it at the shoulder, first in one direction (internal rotation) and then in the other direction (external rotation).
Test Results of the Snap TestÂ
Subluxation (partial dislocation) of the long head of the biceps or biceps brachii tendon out of the bicipital groove will be detectable as a palpable snap in the left hand. And this will indicate a positive snap test.
