I am a huge fan of Mark Comerford. He seems to have a great understanding of how to assess unstable movements throughout the body and provide motor control exercises to help improve those movements. I have begun reading his book, “Kinetic Control: The Management of Uncontrolled Movement” and I love it. It’s like an updated and easier to read Sahrmann. I have a feeling this book will change how I practice almost immediately (I saw a little bit today after reading just the flexion test portion of the lumbar chapter). If you like Sahrmann, you will love this book. I highly recommend it.
