How does cranial manipulation work?
A. The body produces cerebrospinal fluid, which fluctuates 10 to 14 times a minute within the dura mater the covering of the brain and spinal cord. The billions of brain cells expand and contract, which electrically and biochemically and hemodynamically cause a perceived pulse the cranial rhythmic impulse. Because of the articular design of the 22 bones of the skull, motion is permitted. The articular design of the sacrum (at the base of the spine) between the ilea or hip bones permits motion down the spine. Because the membranes covering the brain and spinal cord have elastin tissue and are allowed to expand and relax, the cranial rhythmic impulse can be felt. The amount of movement can be measured in millimeters and can be felt in all parts of the body by a skilled cranial osteopath.
