Craniosacral therapy is a very delicate manipulation and oppression of the skull, pelvis, diaphragm, thorax and the sacrum in order to relax the connective-tissue structures where tension in this area could cause many health problems. The creator of this method is Dr. William Garner Sutherland, who in the twentieth century is the first person to develop a consistent model of the system of joint tensions and rules of their transfer in the skull, the dura mater and the sacrum. Dr. Sutherland showed that there is still movement among the cranial bones even after the completion of its development and he also discovered the law of mutual tensions between the hard lining of the cranial cavity which surrounds the spinal cord and the sacrum with the backbone of the skull. His work allowed researchers such as Becker, Jealous, Kern, Milne, Sills and Upledger to demonstrate the systemic consequences of disturbances in the system and the capability to utilize this therapy as a treatment method of many diseases in all age groups.
