Mike Reinold, DPT, ATC, SCS, CSCS, head athletic trainer for the Boston Red Sox, has a great blog on orthopedic and sports rehabilitation. In addition to keeping his readers informed of the literature and promoting discussion on current concepts, he has an “Essential Reading List” for the best books in athletic training, physical therapy, and strength and conditioning. He recently added Assessment and Treatment of Muscle Imbalances to his list. You can read Mike’s recommendation here. He has some other great books there, including one he wrote with Kevin Wilk and Dr. James Andrews, The Athlete’s Shoulder, which is a bible for anyone working with throwing athletes.
