Technique

A - With the patient in a sitting position with the arm 90 degrees of abduction, the examiner holds the elbow and lateral aspect of the proximal arm, and a strong axial loading force is applied.

B - while the arm is elevated 45 degrees diagonally upward, downward and backward force is applied to the proximal arm. A sudden onset of posterior shoulder pain indicates a positive test result, regardless of accompanying posterior clunk of the humeral head.

Evidence

The sensitivity of the Kim test was 80%, specificity was 94%. The interexaminer reliability between 2 examiners was 0.91.

The accuracy of the jerk test in detecting a posteroinferior labral lesion was the following: sensitivity, 73%; specificity, 98%. 

The Kim test was more sensitive in detecting a predominantly inferior labral lesion, whereas the jerk test was more sensitive in detecting a predominantly posterior labral lesion. The sensitivity in detecting a posteroinferior labral lesion increased to 97% when the 2 tests were combined.
