CranioSacral Therapy was discovered by the American Osteopathic Physician 

During his time as professor for biomechanics at Michigan State University he teamed up with a group of scientists (anatomists, physiologists, biophysicists and bioengineers) to establish the science behind the concept that he later named "CranioSacral Therapy".

William G. Sutherland, DO, was the instigator of this research. In the 1920s he challenged the widely spread assumption that the cranial bones fuse after birth. He found that this was not the case. This was the basis for what is now known as "Cranial Osteopathy", where the focus is on the "sutures" or articulations between the cranial bones. 
Dr. John E. Upledger put emphasis on the answer to the question, "why do the cranial bones need to move and what moves them?" The results of his research with the cerebrospinal fluid being the main driver behind the Craniosacral Rhythm, have now been revised after ongoing research over the past decades.

Currently a team of researchers, led by Dr. Thomas Rosenkilde Rasmussen, Upledger Institute International's Director of Research, has formulated                                                                as the most likely explanation how the Craniosacral Rhythm is produced and regulated.
CranioSacral Therapy focuses on alleviating restrictions, enabling the Central Nervous System to function at a higher level and assisting the body to self-correct and heal.
