Electroacupuncture After Full (EAF) is a procedure in which the conductivity of the tissue is checked by means of a measuring device. With Electroacupuncture After Full, pathological processes in the body should be recorded early, at a time when no irreparable damage has occurred.

The Electroacupuncture After Full unites the concepts of acupuncture and electrotherapy. This diagnosis and therapy method was justified by the physician Reinhold Voll. He developed an electro-acupuncture device in 1971 as a result of his own illness.

On the one hand this device measures the resistance at certain points of the skin surface (partly points from the different acupuncture concepts, partly self-found points), on the other hand it is able to deliver weak electrical impulse currents.

The EAV device consists of a measuring part and a therapy part, which can supply the patient with weak electrical currents. During the examination, the patient holds a metal handle connected to the device, the so-called indifferent electrode. The examiner uses a point electrode to measure the skin resistance at the clearly defined EAV points.
