What is EAV/CEDS? How Does it Work?

Author: Robert Eanes

Every EAV (electro-acupuncture according to Voll) instrument is an OHM meter, i.e. It measures one thing – electrical impedance.
Back in the late 1940’s, Dr. Reinholt Voll, MD began an investigation of the effects of electricity on the human physiology. In his studies, Dr. Voll used a technique known as Impedance or OHM metering. In simple terms, some materials are very electrically conductive, for example metals like steel and copper – electricity flows very easily through metals and therefore there is no substantial resistance on the electricity flowing through the metal. Other materials are not conductive, for example wood or rubber, and since these materials are not conductive, their resistance to electrical current is very high. An OHM meter measures electrical resistance (impedance), and it is also capable of measuring conductance since the inverse of resistance (1/resistivity approximately), is conductance.

Dr. Voll found that if he tested the electrical conductance on any general area of the human body, there was a fairly high level of electrical resistance. This is a curious point since we know that the body has a large volume of electrically conductive fluids within it. But, the skin is very resistant, by its nature to electrical current. Dr. Voll also found that at certain specific locations on the anatomy, the electrical flow is much more conductive, and these points generally correspond to the Eastern Medical Acupuncture points. Therefore, you can use an impedance or OHM meter to test the acupuncture points. This is somewhat simplistic, but it does describe the basic process of EAV.

Author: Robert Eanes Computerized EAV (Electro-acupuncture according to Voll) Systems improve testing efficiency and efficacy. Early generation EAV meters used an analogue needle meter, similar to the speedometer in an automobile. The next progression in EAV technology involved the interfacing of the meter with a computer and custom software. Computers are very useful at displaying information, saving and… Read More »

Author: Robert Eanes At this point, it is obviously better to evaluate different devices based on other criteria as, for example the following factors … Ease of use: Is the software easy to use? Is it user friendly, and does it offer the features, tools and capabilities you need to handle testing now and in the future when… Read More »
