A craniosacral therapy session involves the therapist placing their hands on the patient, which allows them to “tune into the craniosacral rhythm”. The practitioner gently works with the spine and the skull and its cranial sutures, diaphragms and fascia. In this way, the restrictions of nerve passages are said to be eased, the movement of cerebrospinal fluid through the spinal cord is said to be optimized and misaligned bones are said to be restored to their proper position. Craniosacral therapists use the therapy to treat mental stress, neck and back pain, migraines, TMJ syndrome and for chronic pain conditions such as fibromyalgia.
