European Cranio-Sacral Therapy was researched and proposed in 1968 by a Bulgarian research scientist, Boris Ivanov. Dr. Ivanov called this method Clinical Biomechanical Approach. While researching this area, he came to the conclusion that the spinal column is a complicated biomechanical system. On any level of spinal column, any biomechanical disturbances cause an immediate biomechanical realignment of the spinal column. For example, if in the cervical region of the spine any segment develops hypo-mobility (locked segment), the spinal segment located below it starts developing hyper-mobility. In turn, in the thoracic spine, some of the segments start developing hypo-mobility, while some develop hyper-mobility. Also, the biomechanical changes mentioned above will appear in the lumbar spine, and in the lumbo-sacral alignment. These kinds of biomechanical disturbances, produce pain and discomfort, as well as to the development of spinal pathologies such as herniation of disc, spondyloarthritis, degenerative disc disease, etc. Additionally, movement of cerebrospinal fluid is compromised significantly due to disturbances of normal physiological movements (anterior/posterior) in the sacral region of the spine. In Volume 4 of Boris Prilutsky’s Medical Massage DVD series, Boris offers a detailed discussion and hands-on demonstration on correcting the biomechanics of spine, performing scapula manipulation, cervical manual traction, lumbar spine traction, SI joint mobilization, and spinal segment mobilization. European Cranio-Sacral Therapy tremendously contributes to one’s general health, as well as to the prevention of not only spinal disorders, but can possibly prevent Alzheimer’s disease development (which is attributed to the acceleration of cerebrospinal fluid drainage).
