The Japanese doctor Toshikatsu Yamamoto first described the human skull as a microsystem in 1973. YNSA is a quick and easy-to-learn, yet highly effective method for treating acute and chronic pain conditions. Another area of focus is neurological disorders; the use of YNSA has repeatedly proven effective, especially in the treatment of apoplexy. The list of indications extends from functional disorders to the mobilization of musculoskeletal blockages, as well as the treatment of birth defects and developmental disorders in children.

YNSA relies on a special neck and abdominal surface diagnosis also developed by Yamamoto, which serves to monitor and verify the therapeutic effect. Yamamoto has continuously developed and refined his system over more than 40 years. Numerous scientific studies confirm the effectiveness of this specific form of skull acupuncture. This second edition has been thoroughly revised, updated, and expanded. In this book, the reader will find the only authentic introduction to YNSA, precisely described, richly illustrated, and accompanied by impressive case studies from the author's practice.
