This book provides the solid foundation of knowledge therapists need to safely and accurately treat musculoskeletal disorders of the spine. It presents a comprehensive view of applied functional anatomy and biomechanics of the whole spine, examining normal and abnormal function of the spine, the response of tissues to injury, and the effects of age-related changes. Thoroughly referenced and extensively illustrated with over 200 original, high-quality diagrams, it serves as an excellent resource for clinical decision making. The 2nd edition explores several areas in greater depth - including the sacroiliac joint, thoracic biomechanics, muscles - and reviews recent papers and the scientific evidence of functional anatomy.
