that's a key, but I'd minimize talk of so-called "cranial osteopathy", as that just points to a strong psychosomatic component with a bad connotation
I addressed that quite thoroughly in these
two posts.
Cranial osteopathy is an advanced tecnique of osteopathic manual medicine practiced by feeling the cranial rhythm - a scientifically confirmed and objectively measurable "pulse" emanating from the spinal cord and reverberating throughout all tissues that is separate from any other rhythmic mechanism of the body.
The concept of cranial osteopathy is easily understood with the illustration of an arm that has been badly injured and doctors feel for a pulse in the wrist to see if there is major structural interference with blood flow to the hand. The cranial rhythm is more subtle than a pulse, but the exact same concept is used to detect structural problems: if there is a part of the body lacking this undulating rhythm, then they know there is structural interference between point A and point B and may then go out in search of it. This makes cranial osteopathy far more advanced in diagnostics than other methods of structural assessment which rely solely on a preconceived understanding of where everything ought to go and what is within so-called "normal paramaters".
