What is CranioSacral Therapy?
CranioSacral Therapy (CST) is a gentle, hands-on approach that releases tensions deep in the body to relieve pain and dysfunction and improve whole-body health and performance. It was pioneered and developed by Osteopathic Physician John E. Upledger after years of clinical testing and research at Michigan State University, where he served as professor of biomechanics.
Using a soft touch which is generally no greater than 5 grams - about the weight of a nickel - practitioners release restrictions in the soft tissues that surround the central nervous system. CST is increasingly used as a preventive health measure for its ability to bolster resistance to disease, and it's effective for a wide range of medical problems associated with pain and dysfunction.
How does CranioSacral Therapy Work?
Few structures have as much influence over the body's ability to function properly as the brain and spinal cord that make up the central nervous system. And, the central nervous system is heavily influenced by the craniosacral system - the membranes and fluid that surround, protect and nourish the brain and spinal cord.
Every day your body endures stresses and strains that it must work to compensate for. Unfortunately, these changes often cause body tissues to tighten and distort the craniosacral system. These distortions can then cause tension to form around the brain and spinal cord, resulting in restrictions. This can create a barrier to the healthy performance of the central nervous system, and potentially every other system it interacts with.
Fortunately, such restrictions can be detected and corrected using simple methods of touch. With a light touch, the CST practitioner uses his or her hands to evaluate the craniosacral system by gently feeling various locations of the body to test for the ease of motion and rhythm of the cerebrospinal fluid pulsing around the brain and spinal cord. Soft-touch techniques are then used to release restrictions in any tissues influencing the craniosacral system.
By normalizing the environment around the brain and spinal cord and enhancing the body's ability to self-correct, CranioSacral Therapy is able to alleviate a wide variety of dysfunctions, from chronic pain and sports injuries to stroke and neurological impairment.
What can I expect from a CranioSacral Therapy session?
A typical CranioSacral Therapy session lasts from 45 minutes to an hour, and takes place in a quiet, private setting. As a client, you remain fully clothed as you relax on a comfortable, padded massage or treatment table. The practitioner will stand or sit positioned at various points of your head, torso or feet. At times, your practitioner may also support your limbs and spine while helping your body release accumulated tension.
What you experience during a CST session is highly individual. Some people say they feel deeply relaxed, while others describe feeling unwinding sensations as the body releases tension. 
What will I experience after a session?
Just as each individual experiences CST sessions differently, the results can be diverse as well. You may leave in such a relaxed state that you feel like sleeping for hours. Or you may leave full of boundless energy. You may feel a decrease in pain or an increase in function immediately after the session, or the effects may develop gradually over the next few days.
Since CST helps the body resume its natural healing processes, it's common for your improvements to continue weeks after the session. You may also experience a reorganization phase as your body releases previously held patterns and adapts to a new state of wellness.
Is there any condition for which CST shouldn't be used?
There are certain situations where application of CST would not be recommended. These include conditions where a variation and/or slight increase in intracranial pressure would cause instability. Acute aneurysm, cerebral hemorrhage or other preexisting severe bleeding disorders are examples of conditions that could be affected by small intracranial pressure changes.
How many CranioSacral Therapy sessions will I need?
Response to CST varies from individual to individual and condition to condition. Your response is uniquely your own and can't be compared to anyone else's - even those cases that may appear to be similar to your own. The number of sessions needed varies widely - from just one up to three or more a week over the course of several weeks.
