Review Question - QID 7640

A 21-year-old minor league pitcher reports decreasing velocity and ability to target his pitches over the last 2 months. He notes that his arm will start to feel heavy in the later innings and notes pain in the posterior aspect of his shoulder in the late cocking phase of his motion. He denies any specific event that initiated his symptoms. Examination reveals symmetric rotator cuff strength and no increased anterior or posterior translation of either shoulder. 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. The left shoulder has 95 degrees of external rotation and 60 degrees of internal rotation. He has pain with an O'Brien's maneuver and a negative apprehension sign. What is the next most appropriate step in management?
