What Is Cranial Osteopathy?

Even though Im no longer taking the cranial elective, I still feel its important for my learning that I have a greater understanding of what cranial osteopathy is. Hence after some research this is what I have found out.

Cranial Osteopathy - The five fundamental principles of the cranio sacral mechanism
The cranial concept is a system of therapy that is being used widely throughout the world and I will try to explain the fundamental principles that apply to it. The cranial concept was first developed by an osteopath called William Garner Sutherland in the early 20th century and he was the first to coin the phrase cranial-osteopathy. Since Sutherland, there have been practitioners like Upledger who have further developed the theory and other branches have developed such as cranio-sacral therapy (craniosacral). The system of cranial osteopathy and cranio-sacral therapy is becoming more and more popular in Israel and in Jerusalem specifically patients are beginning to benefit from it due to greater awareness.

Whether an osteopath uses cranial osteopathy, structural osteopathy, classical, visceral or functional osteopathy, the same principles of diagnosis are used which are based on a system that applies anatomy and physiology in order to prevent disease. The osteopath considers the whole body as a unit all of whose parts need to be properly nourished by its internal fluid environment in order to function, heal itself and thus combat disease.

When the osteopath considers the body as a whole, inevitably this includes the cranium and all of it components; it's bone, cartilage, membranes and internal environment that is nourished by blood-vessels and nerves.

5 fundamental principles exist in cranial osteopathy:

1) That an inherent mobility exists within the brain and spinal cord.
The neural tube develops in the embryo with 2 anterior sections that invaginate and curl up like a ram's horn to form the cerebral cortex. Since it is believed that there is inherent motility within the brain, the pulsating motility responds by curling and uncurling in the way it was developed.

2) Fluctuation of the cerebro-spinal fluid.
There are a number of theories as to how the CSF fluctuates and what the basis of its movement is. For the osteopath however, the important factor is that changes in pressure can be palpated along the route of the CSF and any existing restrictions may alter the CSF fluctuation and have consequences on the body.

3) Motility of intracranial and spinal membranes.
The spinal membranes that form the structures of the intracranial membranes are the falx cerebri and the 2 tentorium cerebelli. These sickle-shaped structures arise from a common origin at the straight sinus known as "The Sutherland fulcrum". The insertions of these membranes are along various points around the cranium. The falx cerebri originates at the internal occipital protuberance, travels upward and forward and eventually insert into the crista galli of the ethmoid bone. The 2 tentoria cerebelli pass along the transverse ridges and the two converge on the body of the sphenoid and insert onto the anterior clinoid process. Together, these membranes constitute the reciprocal tension membranes linking the cranium to the sacrum, functioning as a unit around a common fulcum - the Sutherland fulcrum.

4) Mobility of the bones of the skull.
Whilst the skull may appear to be a solid structure in fact it has zigzag edges which grow together to form movable sutures. These joints evolve from smooth-edged plates of membrane in the newborn and eventually evolve into articulations with slight movement according to the contours of the two surfaces.

5) The involuntary mobility of the sacrum between the ilia.
Not to be confused with movement of nutation and counter-nutation of the sacrum between the ilia, the cranial-osteopathic concept considers the sacrum having an involuntary, respiratory mobility. We have already mentioned the mobility of the intracranial and spinal membranes and it is the lower attachment of these membranes to the sacrum that results in the direction and containment of the sacrum's movement. The movement is a physical extension of the primary respiratory mechanism and allows the sacrum to flex an extend at the level of the second sacral vertebra.

It is with the comprehension of these five fundamental concepts that the cranial osteopath starts to understand the craniosacral mechanism. With a knowledge of the anatomy of the cranium, the physiology of the respiratory mechanism and the cranio-sacral rhythm the osteopath embarks upon a path of therapeutics that are applicable to all kinds of ailments experienced by patients.
