A gentle form of manipulation, craniosacral therapy is a hands-on healing technique typically practiced by physical therapists, massage therapists, and chiropractors. Craniosacral therapists manipulate the craniosacral system, which includes the soft tissue and bones of the head (cranium), the spine down to its tail end (the sacral area), and the pelvis. They also work with the membranes that surround these bones and the cerebrospinal fluid that bathes the brain and spinal cord. Although the therapist uses a touch so light that many patients don’t even notice it, most people report feeling profoundly relaxed after a treatment.
