CranioSacral Therapy was developed by Osteopathic Physician, Dr. John E. Upledger and has its roots in Cranial Osteopathy. The basis of his techniques were formed while he was working as a professor of Biomechanics at Michigan State University. There, he was leading a team of anatomists, physiologists, biophysicists, and bioengineers to test the mechanical properties of the cerebrospinal fluid (CSF) and meninges along with their bony attachments. These tissues are collectively referred to as the CranioSacral System.
The CranioSacral System is responsible for protecting the health of the brain and spinal cord. The cerebrospinal fluid delivers nutrients, hormones, and neurotransmitters to the cells of the nervous system. It also contains chelating agents that bind to metabolic wastes and toxins, aiding in their removal.
The meninges are 3 layered connective tissue membrane system that surround the brain and spinal cord. They form a semi-closed hydraulic system that facilitates the circulation of the cerebrospinal fluid. They also help to resist physical forces such as those caused by a concussion, traumatic brain injury, whiplash, etc. that may cause harm to the delicate neural tissues. Recently, it has also been discovered that the meningeal system plays a role in regulating the passage of immune cells, toxins, pathogens, and debris from the brain to the cervical lymph nodes.
The techniques used in CranioSacral Therapy are very gentle. They work because they are precise. The right pressure, in the right place, at the right angle. The therapist feels for the source of the tensions, figures out which ones are primary and applies the appropriate amount of force in the appropriate direction.
In most cases additional therapies are incorporated into the session, including Visceral Manipulation, Neural Manipulation, Manual Lymphatic Drainage, Myofascial Release, NeuroMuscular Therapies, as well as, Passive and Active Stretching techniques.
