When Nakatani first developed his procedure of electronic evaluation
by measuring skin conductance at the points of the wrists and ankles,
he created one of the most significant acupuncture diagnostic methods
that have yet to be created in either contemporary or traditional
acupuncture. When one compares the findings of learned Asian
Masters of Acupuncture and Pulse Diagnosis, who will literally palpate
the 12 pulse positions for as long as 15-20 minutes per wrist, with
the findings of Ryodoraku (Nakatani's method of diagnosis), they
are most often identical or extremely close.
Ryodoraku is practiced by measuring the conductance of skin at the
Source points (points on acupuncture channels that show relative
energetic state of the whole chennel) with an instrument designed
specifically for this purpose.
In our clinic we use Rista EPD: instrument designed to combine Eastern Traditional
Meridian Diagnostic System with Western electro-measurements and computer assisted
analysis of the reading.
