Do the bones of the cranium actually move? And if so, how much?
One of the foundations of Craniosacral Therapy is the movement of the bones of the cranium in response to the tide-like movements and potency of the cerebrospinal fluid. In particular the junction between the base of the sphenoid and occiput (variously called the SBS, SBJ or SOJ) has historically been considered a key fulcrum point for movement of the whole cranium and beyond.
In this presentation, Andrew Cook, long time Craniosacral therapist and teacher, asks the questions:
How can we reconcile the standard cranial textbooks with modern advances in anatomy, physiology and MRI/CT/Ultrasound imaging?
Does the production of cerebrospinal fluid drive cranial motion?
How much does the SOJ actually move?

Of interest to all manual therapists, but particularly cranial osteopaths and craniosacral therapists, this presentation will shed a light on what we are feeling under our hands, whether that is working with adults or babies.
