Cranial Osteopathy, also named osteopathy in cranial field (OCF), was explored by the American osteopathic physician William Garner Sutherland (1873-1954) in the 1940s, after years of studies with the founder of osteopathic medicine, Andrew Taylor Still (1828-1917).
Sutherland made a significant contribution when he proposed the existence of an inherent movement between the dura, sacrum, and cranial bones known as the primary respiratory mechanism (PRM).
The PRM includes:
Neuronal and spinal cord motility;
Fluctuation of the liquor/cerebrospinal fluid (circulates around the brain and spinal cord for neurological functions);
Tension membranes motion (spinal and cranial dura mater that cover and feed the central nervous system and these are the primary way of communication between the brain and column);
Skull bones motion;
Sacrum bone motion.
In fact, various bones of the skull fit together in a way that permits (small) motion that can be felt by cranial osteopaths.
Osteopaths can feel the cranial rhythmic impulse (CRI) with a gentle hands-on touch, to detect the area where the body tissue moves well or is “stuck”.
The treatment can also be focused on the “stuck spots” with small and gentle movements to restore optimal balance and function to the tissues.
In fact, as a philosophy of osteopathic medicine, Health can be reached when all fluid components, like the cerebrospinal fluid, are running harmoniously to nourish all the body’s structures.
The work of the osteopath is to help the normal body fluids, so health can continue.
