What is the O Brien’s test for?
The O’Brien test, or active compression test, is a simple procedure to assess the cause of shoulder pain. If you experience pain or clicking during the test, you may have a torn labrum or an abnormality in your acromioclavicular (AC) joint. O’Brien’s active compression test was primarily developed for assessment of Acromioclavicular joint pathology following a patient’s demonstration of what reproduced their shoulder pain. O’Brien noted in a series of patients it was also excellent for detecting labral pathology.The O’Brien test can help diagnose a problem in your AC joint, such as separation in your joint or cartilage wear and tear. Your labrum is a bumper-shaped piece of cartilage that lines the rim of the socket bone of your shoulder (glenoid).
