We've done the electropunctural diagnosis by Y.Nacatani of 40 patients with vegetative dystony and 55 healthy people. The research was done in 24 points (one point on each channel, left and right). We investigated the electroconduction of acupunctural channels as a reflection of their function. The patients with vegetative dystony had the specific diagram of the electroconduction. The healthy people had the "normal" diagram. The electropunctural diagnosis according to Y.Nacatani helps to early reveal this pathology, especially within the screening investigation.
