Review Question - QID 7746

A 19-year-old college pitcher reports posterior shoulder discomfort that started recently with pitching. He is able to throw with normal velocity and control, but his pain in the early acceleration phase of throwing is getting worse. Examination reveals symmetric rotator cuff strength and no increased anterior or posterior translation of either shoulder. He has some discomfort with his shoulder in abduction and external rotation. Supine range of motion of the right shoulder in 90 degrees of abduction reveals external rotation to 100 degrees and internal rotation to 25 degrees. His left shoulder has 95 degrees of external rotation and 45 degrees of internal rotation. He is not playing the next 2 weeks and requests some exercises that he can do on his own. Which of the following exercises will most likely improve his shoulder symptoms?
