Cranio-Sacral Therapy

One of most gentle treatment modalities around, cranio-sacral therapy effects movement of the skull bones and sacrum. This movement is unperceivable by the human eye. The skull (cranium) is made up of 21 closely-knit bones that allow for an expansion and contraction of the brain and fluids. (See Cr 1)

The pumping action within the brain circulates nourishing fluid throughout the brain as well as around the spinal cord. (See Cr 2, 3)

Although the cerebrospinal fluid doesn't circulate beyond the brain and spinal cord an energetic wave is transmitted into the limbs and there can be
felt as a rotational wave of movement. The amplitude of the cranial wave is reportedly 25 microns (half the thickness of a sheet of writing paper). In a healthy person there are 8-14 cycles per minute. When a person has a fever or consumes considerable caffeine, the frequency is increased. During meditation the cranial motion slows and can become synchronous with the breath. Enhancing one's breath will stimulate/regulate one's cranial wave.

The cranium and its membranes move in rhythm with the sacrum located at the end of the spine, hence the name "cranio-sacral". (See Cr 4)
