A study1 by Efstathios Chronopoulos for diagnostic value of physical tests for isolated chronic acromioclavicular lesions, he compared the three tests (acromioclavicular resisted extension test, active compression test and Cross Body Adduction Test) that is used in evaluation of acromioclavicular joint.

The accuracy of Cross Body Adduction Test was as following:

The study concludes that these tests have utility in evaluating patients with acromioclavicular joint pathologic lesions, and a combination of these physical tests is more helpful than isolated tests.
