A manual osteopathic therapist embraces the unity of structure and function of the human body through the four principles of osteopathy. 1. The human body is a unit; it works as a single entity. 2. The human body has self-governing means. 3. Structure and function are mutually interrelated. 4. The human body has the capability to protect, repair, and regenerate itself to preserve its function. A manual osteopathic therapist will restore the dysfunctions of the body’s movement patterns through gentle, whole-body manipulations of the four systems of the body: skeletal, cranial-sacral, fascial, and visceral.
