Research supporting Osteopathy in the Cranial Field (OCF) had been well established in the scientific literature long before William Garner Sutherland’s first documentation of the Primary Respiratory Mechanism in the late 1920’s.1,2,3,4 Like Dr. Still, Dr. Sutherland based his concepts on systematic observation, private research, and the published science and philosophy of his time.

In 1914 Louisa Burns DO began her landmark osteopathic research.5 Since then, the osteopathic profession has continued to pursue disciplined research concerning osteopathic principles. 6,7 A significant body of research produced by independent scientists and other health care professions has also proven supportive of OCF.8

Today, research supportive of the cranial concept is flourishing. Recent technological advances and increased funding have enabled research scientists to further study the fundamental principles of OCF.

Research supporting OCF can be classified into three basic categories:

  1. Explaining the underlying physiology (how things work). Dr. Sutherland described five phenomena as the basic premise for OCF. Links are provided below to explore relevant research.
    1. The inherent motility of the brain and spinal cord.
    2. The fluctuation of cerebrospinal fluid.
    3. The mobility of intracranial and intraspinal membranes.
    4. The articular mobility of the cranial bones.
    5. The involuntary mobility of the sacrum between the ilia.
  2. Confirming the positive clinical effects of treatment.
  3. Verifying palpatory reliability

OCF has been substantiated by a sound body of scientific and clinical research. Further research is important for the continued understanding and confirmation of osteopathic principles and practice.
