The Perrin Technique™ is based on Dr. Perrin’s theory that different stress factors whether physical, allergies, emotional or infections lead to an overstrain of the sympathetic nervous system. Further investigation has led to a probable cause of this nervous system overload being a build-up of toxins in the fluid around the brain and the spinal cord. Some of the poisons caused by infection or inflammation in the head or spine flow through channels from the brain into the lymph ducts of the head face and neck. The toxins are also meant to drain down the spinal cord and out into the lymph ducts lying along the spine. In a ME/CFS sufferer, there is a backflow of these normal drainage points which leads to further toxicity and dysfunction of the central nervous system. This leads to all the many symptoms we see in ME/CFS.
