Book excerpt: An essential resource for bodyworkers, physical therapists, and sports medicine practitioners--a vital guide to understanding the anatomy, form, and mechanics of the human foot. Understanding the Human Foot is a full-color, up-to-date overview of the structure and function of the foot, written for physical therapists and movement practitioners looking to deepen their understanding of holistic anatomy. Readers will gain perspective on the impacts of foot shape; the interdependence of form and function; and the cellular processes that determine how our tissue is designed. Most importantly, author James Earls demonstrates how the foot relates to and interacts with the rest of the body during movement, laying the groundwork for a comprehensive holistic approach to assessing, troubleshooting, and addressing functional and structural foot issues. Starting with big-picture questions--what is a foot, and what is it used for? How does it work, both on its own and as part of a whole?--before zeroing in on the 26 bones, 33 joints, and many muscles that make up the foot, Earls teaches anatomy the way he wishes he'd been taught 30 years ago: with a holistic emphasis on interrelated systems, real-life applications, and approachable, easy-to-understand language. He shares: Full-color illustrations for easy reference and comprehensive understanding An overview of the bones, ligaments, and extrinsic and intrinsic muscles of the foot How your gait impacts the rest of the body--and can cause problems as high up as the neck and shoulders How to assess structural problems of the foot Corrective exercises A footwear guide to choosing the best shoe for your foot type
