Muscles and Meridians is a unique book that breaks new conceptual ground in the realm of human movement. Firmly based in an understanding of evolutionary and developmental biology, this volume introduces some of the keys that open the way to an understanding of the Contractile Field (CF) model - a novel concept which promotes a fresh approach to exercise and represents a valuable means of understanding and treating musculoskeletal disorders. The CF model represents a whole-organism approach to an appreciation of human movement. The fundamental biomechanical architecture of vertebrates imposes patterns of movement on our spine, patterns that offer the keys needed to begin a more robust understanding of human movement. The CF model suggests that sense organs are embedded in fields of contractility, and that the musculature of the viscera and the role of the kidneys need to be incorporated in this attempt to develop such a model. Fields of contractility are defined, borders between fields are identified, and field interaction considered. The model also suggests a new assessment methodology: the Archetypal Postures. Many musculoskeletal aches and pains, such as back pain, are non-attributable to a standard tissue-related diagnosis. Rather we need to focus on the interrelationship of many named tissues via the emergence of postures that are deeply embedded in our evolution and childhood development. Archetypal Postures are essential to the 'tune' of the musculoskeletal system.By showing a pattern of correlation, the CF model also sheds light on the Chinese map of the meridians suggesting a theory that unravels the complexity of the ancient map which the modern biosciences have been unable to comprehend or identify. Muscles and Meridians presents an approach to musculoskeletal anatomy which will be widely applicable to all professionals who have an interest in human movement: physiotherapists, osteopathic physicians, osteopaths, chiropractors, acupuncturists, exercise scientists, manual therapists, and personal trainers.
