The Rule of the Artery program evolved directly from Osteopaths who were having palpatory experiences with their patients that they could not explain under the existing osteopathic models or paradigms.  This stimulated an exploration of Dr. Still’s writings and an investigation of the circulatory system and how this related to clinical practice.  The journey began with the principle “The Rule of the Artery is Supreme” and developed into an exploration of the heart, its’ function and relationship with the rest of the body.
