Purpose[edit | edit source]
This test is used to detect posteroinferior instability of the Glenohumeral joint.
Technique[edit | edit source]
While stabilizing the patient’s scapula with one hand and holding the affected arm at 90° abduction and internal rotation, the examiner grasps the elbow and axially loads the humerus in a proximal direction.The arm is moved horizontally across the body. A positive result is indicated by a sudden clunk as the humeral head slides off the back of the glenoid. When the arm is returned to the original position, a second jerk may be observed, that of the humeral head returning to the glenoid.[1]
Evidence[edit | edit source]
A systematic review of the validity and accuracy of clinical tests used to detect labral pathology of the shoulder showed the +LR of the Jerk Test to be LR 34.71 and the -LR to be 0.27[3]
