Since initial publication in 2001, the reach and application of the ideas in this book have far outstripped this author’s expectations. We and our staff have been invited to present these ideas and their application on every continent save Antarctica to a wide variety of professionals, including orthopedists, physiatrists, physiotherapists, chiropractors, osteopaths, psychologists, athletic and personal trainers, performance coaches, yoga teachers, martial artists, massage therapists, dancers, and somatic educators of all stripes. The book is now available in 12 languages. A simple Google® search of Anatomy Trains now yields nearly 6,000,000 hits, as therapists and educators find useful applications far beyond our original conception. This third edition includes many small updates and corrections that arose out of our continuing teaching and practice, as well as preliminary evidence from fascial dissections. We have been able to include some recent discoveries made in the fascial and myofascial world since the second edition (much of it summarized in Fascia, the Tensional Network of the Human Body, 2012, Schleip R, Findley T, Chaitow L, Huijing P; Edinburgh: Churchill Livingstone), as well as to fill in areas where our initial ignorance of the wider world has been rectified. This edition benefits from updated artwork by Graeme Chambers, Debbie Maizels and Philip Wilson. New client assessment photos have been produced by Michael Frenchman/Videograf and Pedro Guimaraes/Pamedia Design. The book is designed to allow rapid comprehension of the relevant concepts for a casual reader, or a detailed analysis for the curious.
