Thanks for the suggestion!For the meat and potatoes of how things go awry, Shirley Sahrmann does an excellent job of cataloging dysfunction in detail. Keep your eyes out for cheap, used copies of her two volumes on Amazon.
Though if you want a supremely clear explanation of the musculoskeletal system, there is no equal to Dr. Adalbert Kapandji's three volumes. Recent copies of his books are overpriced, but you can get them from your library for free.
That's actually the textbook for our class. It's a good book for sure and cleared up some things after reading it. I was hoping to find something on YT like there is for Gross Anatomy but no luck yet.https://www.google.com/search?q=kinesiolgy+of+the+musculoskelatl+system&ie=utf-8&oe=utf-8#q=kinesiology+of+the+musculoskeletal+system
Classic text that is used in most PT programs. Goes into a decent amount of detail on biomechanics and calculations without detracting too much from the clinical relevance. Has been very helpful for me so far during the basic sciences portion of our curriculum.
