As always, seek professional advice before using any of the methods listed.
Shiatsu (Kanji: 指圧; Hiragana: しあつ) is a form of Japanese bodywork based on the theoretical framework of Traditional Chinese Medicine.
It is the most widely known form of Accupressure, and has been used in Japan for more than 1,000 years, to treat pain and illness and for general health maintenance, by using a series of techniques, practitioners apply rhythmic finger pressure at specific points on the body in order to stimulate chi, or the vital energy.
In the Japanese language, shiatsu means "finger pressure". Shiatsu techniques include massages with fingers, thumbs, and palms; assisted stretching; and joint manipulation and mobilization.
To examine a patient, a shiatsu practitioner uses palpation and, sometimes, pulse diagnosis.
Shiatsu derives from a Japanese massage modality called anma. The Japanese may have adapted anma from tui na, a Chinese bodywork system that arrived in Japan during the Nara period (710–793 CE). Tokujiro Namikoshi (1905–2000) founded a shiatsu college in the 1940s, and is often credited with inventing modern shiatsu. Shiatsu in Japan is regulated by the Ministry of Health, Labour and Welfare.
There is no official evidence that shiatsu is an effective medical treatment, therefore, as always, please make up your own mind.
