Kim’s Test | Posteroinferior Labral Tear | Shoulder Instability Assessment

According to a study done by the inventor of the test themselves in the year 2005,  Kim’s test has a sensitivity of 80% and a specificity of 94% in the diagnosis of posteroinferior labral tears. However, more studies will have to investigate the accuracy of this test with stricter study designs. For this reason, Kim’s test has a moderate clinical value in our opinion.

To execute the test, the patient is in sitting position, and the examiner positions himself behind. The examiner stabilizes the scapula with one hand and holds the patient’s affected arm at 90° abduction and internal rotation. Then the examiner applies a longitudinal force through the humerus at the elbow and moves the arm into horizontal adduction.

This test is positive if the patient experiences a sudden onset of posterior shoulder pain and a click in the shoulder. A painful response is also a predictor of failure for conservative treatment.
