Recently I completed the first level of Craniosacral Therapy training and I am now able to offer this work, either integrated into a massage treatment, or as a treatment unto itself. If you want an entire session of craniosacral therapy, you would simply wear comfortable clothing and be on the table, rather than being treated using sheets and draping.
The following description is from The Upledger Institute International:
CranioSacral Therapy (CST) was pioneered and developed by osteopathic physician John E. Upledger following extensive scientific studies from 1975 to 1983 at Michigan State University, where he served as a clinical researcher and Professor of Biomechanics.
CST is a gentle, hands-on method of evaluating and enhancing the functioning of a physiological body system called the craniosacral system - comprised of the membranes and cerebrospinal fluid that surround and protect the brain and spinal cord.
Using a soft touch generally no greater than 5 grams, or about the weight of a nickel, practitioners release restrictions in the craniosacral system to improve the functioning of the central nervous system.
By complementing the body's natural healing processes, CST is increasingly used as a preventive health measure for its ability to bolster resistance to disease, and is effective for a wide range of medical problems associated with pain and dysfunction, including:
Chronic Neck and Back Pain
Central Nervous System Disorders
Concussions and Traumatic Brain Injuries
Alzheimer's Disease and Dementia
Spinal Cord Injuries
Stress and Tension-Related Problems
Fibromyalgia and other Connective-Tissue Disorders
Temporomandibular Joint Syndrome (TMJ)
Neurovascular or Immune Disorders
Post-Traumatic Stress Disorder
And here is a good article about craniosacral therapy from the Cranial Therapy Centre.
