I was recently asked, "What's the most important book you've read in your career?" The answer was really simple: "Diagnosis and Treatment of Movement Impairment Syndromes," by Shirley Sahrmann. Early in my career - especially in light of my own shoulder pain history - Sahrmann's work was an amazing contrast to the medical model of care that focused entirely on treating symptoms (medical diagnoses) instead of investigating root causes (movement diagnoses). Sahrmann proposes countless functional tests and corrective exercise interventions aimed at treating the causes of the problems rather than the compensations that emerge after dysfunction has emerged. This book has profoundly impacted the way that some of the industry’s greatest minds train their clients and athletes and themselves. To be blunt, Shirley Sahrmann has likely forgotten more than most physical therapists will ever know. Full disclosure: it reads like stereo instructions, and you may only cover 2-3 pages at a time. However, when you finish the book, you could restart it immediately and learn something new each time you work through. The reason is simple: the movement impairment syndromes model is something that "clicks" with each new client/athlete/patient you encounter. Not every "shoulder impingement" is the same; you appreciate why they're all unique. If you’re serious about your own education, and have the best interests of your clients and athletes in mind, you owe it to yourself to pick up a copy of this classic. amzn.to/47xBIGj
