The domain of Nuad Boran includes all ‘sensip’ which need to be irrigated by moving liquid elements. Once a good circulation of ‘sen’ has been reestablished, Thaïs trust the body’s capacity for self-regulation, just as they trust plants to grow as soon as they are well irrigated. Land has been cultivated during centuries by repeatedly plowing back and forth furrows. This is the root concept Thaïs apply when working on ‘sen’: one follows the tendon-muscular lines all the way up and down. Muscular fibers are ploughed along the myofascial lines that are instinctively identified because the practitioners have seen their elders doing so, because palpation makes it easy to locate these lines and because the
physical condition of the treated patients improves spectacularly.
 

The most similar approach to the work on Thaï lines is that of Chinese medicine. In addition to the twelve main lines used in acupuncture, there are associated tendon-muscular lines (jing-luo) which run through the whole body following networks which are very similar to ‘sensip’. In Chinese medicine however, these paths are not meant for
acupuncture, but for mobilization and muscular pressure preceded by search for the causes.

The Thaï viewpoint depends on tangible effects. Anticipating the felt affect and a sort of « muscular empathy » are both part of an ancestral instinct accumulated from one generation to another which give Thaï bodywork its own characteristics.

Nuad Boran works on tendon lines which are similar to Chinese muscular lines while adding the specific Thaï style:
rhythms originating in Theraveda Buddhism - diffuse implicit kindness (Mitta) in treating affects and clever integration of gravitational effects to attain greater results with less effort.

Dr Pennapa Subsharoen, President of the Institute of Alternative and Traditional Medicine in Thaïland has inspired much experimental research on the efficacy of NB. She is also a member of the consultative Committee for evaluation of traditional medicines at the World Health Organization. Ms. Susharoen, member of a family of traditional Thaï doctors and a medical doctor herself, graduated from the University of Songla to become a doctor in Public Medicine with a thesis on the traditional Thaï health system. In defining sensip work, she writes: (It is) « To feel the muscles the length of the disturbed lines and healing by applying pressures of varying intensity which brings back harmony ».
