. Yamamoto New Scalp Acupuncture (YNSA) and TCM

SINCE 1960

The Yamamoto New Scalp Acupuncture (YNSA) was discovered in the 1960s and first presented to the world at the Ryodoraku Congress held in Osaka, Japan, in 1973. Throughout more than 40 years, Dr. Yamamoto has not stopped working to improve and complete the system.
In the early 70s, this method was made up of five Basic Points located on the forehead. It consisted of a single microsystem or somatotope, that is, correspondence of a body area point with a specific zone of the central nervous system, organ, muscle, etc. Since then, Dr. Yamamoto has discovered many more points as well as other somatotopes, and not only in the head but also in other body parts.

In traditional Japan, acupuncture was usually practiced by massage therapists, and therefore, it was not socially well-recognized. The Japanese medical community and society did not recognize the effectiveness of this technique until a few years ago, and there is no doubt this has acurred thanks to the tireless activity of Dr. Yamamoto.


In the 1960s, after studying and working abroad for 10 years, Dr. Yamamoto returned to Japan along with his wife Helene, a German nurse who has accompanied him throughout his career, and their two daughters. In addition to being a gynecologist and surgeon, Dr. Yamamoto is an also anesthetist, which was very useful to start treating patients in his hometown of Nichinan. There were a lot of people who suffered from osteoarticular pain after working for years in water-covered rice paddies.

Dr. Yamamoto began to practice in a humble wooden cabin, where he treated diseases related to areas as different as gynecology, internal medicine, obstetrics, surgery, and pain treatment through nerve blocks, which are basically anesthetic drug injections. Once, Dr. Yamamoto mistakenly administered only a saline injection to a peasant, and he accidentally neglected to add the anesthetic agent: novocaine. However, the next day, his patient returned to the consultation stating that the pain had gone and asking for another injection to make sure joint pain did not come back again. That same night, Dr. Yamamoto turned to the experience of a massage therapist, who provided him with an old book about acupuncture.

From that moment, Dr. Yamamoto decided to continue giving shots without anesthetics and started using acupuncture needles. This was the beginning of the Yamamoto New Scalp Acupuncture (YNSA), currently applied with great success worldwide by thousands of therapists, and thus helping hundreds of thousands patients.

The wooden cabin became too small, so Dr. Yamamoto decided to build a hospital with the invaluable help from his brother, who guaranteed a mortgage. More than 2,000 surgeries with acupuncture anesthesia were performed in these hospital facilities, such as appendectomies, deliveries, Cesarean births, hysterectomies, intestinal obstruction repairs and amputations. Subsequently, Dr. Yamamoto would also include hemiplegic patient treatment.



In the Yamamoto New Scalp Acupuncture (YNSA), there are several diagnostic, therapeutic and diagnostic-therapeutic areas (not only in the head), and the following stand out among them: neck, upper and lower limbs, pubis and abdomen (developed from oriental abdominal acupuncture and adapted to scalp acupuncture). Therefore, there is a correlation between brain, neck and abdomen points with the rest of the body and with each other.

An association between the so-called Y Points or YPSILON Points and the 12 cranial pairs is made through the diagnostic technique in neck and abdomen areas. All internal organs are located at the Y or Ypsilon Points. These points maintain a correspondence to the ZANG FU, which are meridians according to TCM and internal organs according to the Western approach. The system distinguishes between the YIN somatotope (on the anterior part of skull) and the YAN somatotope (on the posterior part of skull).

As a general rule, needle insertion is performed ipsilaterally in the case of pain treatment or musculoskeletal disorders, but contralaterally in the case of hemiplegia; although this pattern is subject to modification depending on diagnosis.
