As a result of his clinical experience, he developed clinical tests, such as the Gerber Lift Off test [4] for a subscapular insufficiency. He is author of >300 scientific articles that were cited over 15000 times (as per Feb. 2014).
The Gerber Lift-off test is the established clinical test for examination of the subscapularis. [3] The bear hug test (internal rotation while palm is held on opposite shoulder and elbow is held in a position of maximal anterior translation) for subscapularis muscle tears has high sensitivity.
Empty beer can test: a positive test indicates rotator cuff tear, specifically, supraspinatus muscle tear; Drop arm test: a positive test indicates a supraspinatus tear; External Rotation test: a positive test indicates an infraspinatus or teres minor tear; Lift-off test: a positive test indicates subscapularis pathology
Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.
Jobe's test is a physical exam test that is used to detect anterior shoulder instability. It is used to distinguish between anterior instability and primary shoulder impingement. This test should be performed after the Apprehension test. [3] This test was named for Christopher Jobe. [4]

The Gerber method is the primary testing method in Europe and much of the world. [2] The fairly similar Babcock test is used primarily in the United States, although the Gerber method also enjoys significant use in the U.S. as well. [3] The Gerber method was developed and patented by Dr. Niklaus Gerber of Switzerland in 1891. [4]
To perform the test, the examiner grasps the wrist with their thumb over the scaphoid tubercle (volar aspect of the palm) in order to prevent the scaphoid from moving into its more vertically oriented position in ulnar deviation. For the test, the wrist needs to be in slight extension. The patient's wrist is then moved from ulnar to radial ...
