Craniosacral therapy is a gentle technique that follows the philosophy explored by John Upledger that holds that the sacrum and coccyx both affect and are affected by motions in the Cranium. The bones in the skull far from being fused as i was taught as a child but instead are connected with sutures, fissures that act like a different kind of joint. My understanding is that the bone formations in the skull are there with an important function. The sutures are a special kind of joint that allows for gentle expansion and contraction of the skull and allows for a flexibility so that every contact with a hard surface doesn’t jostle the brain or lead to brain damage. The theory explores the concept that the sinuses in the skull and brain are part of a pressure sensitive system that regulates the flow of cerebral spinal fluid that bathes the brain and the spinal cord. There are normal patterns and normal rhythms that when off kilter are reflective of other dysfunction in the body and that those dysfunctions can be addressed by the methods he describes.
When I was young I was told that babies have lots of different bones in their heads so they can get out of the birth canal by easily collapsing and protecting the brain, and when you get old they fuse because hopefully you’ll be too smart to ever try to squeeze through a 3″ opening again. Early in life I noticed the phenomenon than when working on the head and holding my hands still it would feel kike movement started under my hands. This Therapy is not uniformly believed to be effective and several people scoff at the concept. I have found that for some people these techniques are immensely effective in changing long term stuck pain.
