Craniosacral therapy (CST) is a form of bodywork or alternative therapy using gentle touch to manipulate the synarthrodial joints of the cranium. A practitioner of cranial-sacral therapy may also apply light touches to a patient's spine and pelvis. Practitioners believe that this manipulation regulates the flow of cerebrospinal fluid and aids in "primary respiration".[2] Craniosacral therapy was developed by John Upledger, D.O. in the 1970s, as an offshoot of osteopathy in the cranial field, or cranial osteopathy, which was developed in the 1930s by William Garner Sutherland.
