Electro acupuncture refers to the therapy in which acu points are stimulated by electrodes carrying minute electrical currents, the principles of treatment being the same as that of classical acupuncture. Whereas this therapy was already in vogue in many parts of the world, pioneering research in electro acupuncture was carried out by Dr. Reinhold Voll, an allopathic physician of Germany, around the mid twentieth century. This research was so extensive and its results so promising that it evolved into a therapy of its own and came to be known as ‘Electro Acupuncture According to Voll’ (EAV) after the name of its inventor.
