"Osteopathy is a total system of healthcare which professes and teaches the osteopathic philosophy: 1. The body is a unit. 2. It has its own self-protecting and regulating mechanisms. 3. Structure and function are reciprocally interrelated. Treatment considers the preceding three principles. Osteopathy also encompasses all recognized tools of diagnosis and healing including osteopathic palpatory and manipulative treatment methods."
William & Michael Kuchera, 1991
