Re: Volume 22, Issue 3 Dear TAC: This is a reply to the charge [made in a letter to "The Forum" (V. 22, 1.4)] from the uninformed doctor concerning testing procedures known as; EAV, Electro-Dermal Screening, GEA, Meridian Therapy, PEP, etc. The accusation has been made that it is "quack" medicine, not listed with the FDA, and information concerning it degrades professional magazines. Some of the instruments are listed with the FDA as Screening Devices. The need to list appears to be integral- ly linked to the "claim" as to what these instruments are interpreted as revealing about the person being tested. A great deal has been discovered, and legitimate diagnostic and therapeutic devices based on these sound discoveries have emerged. In the early 1950's, Reinhold Voll, a German medical doctor and scientist, developed an electronic testing device for finding acupuncture points electrically. He was successful in finding acupuncture points and demonstrating that these points, had a different resistance to a tiny electrical current passed through the body, than did the adjacent tissues. Many other researchers have also verified that electrical conductance at the acupuncture points is significantly greater than the surrounding tissue. Voll, then, began research to identify correlations between disease states and changes in the electrical resistance of the various acupuncture points. He thought that, if he could identify electrical changes in certain peripheral nerval data access points associated with disease, then he might be able to identify those diseases more easily, or earlier. Voll was successful in identifying many acupuncture points related to specific conditions and published a great deal of information about using acupuncture points diagnostically. He found, for example, that patients with lung cancer had abnormal readings on the acupuncture points referred to as lung points. These changes in peripheral nerval data access points resistance related to lung cancer have been verified by researchers from UCLA and USC. John Milovich, A.P., N.D., L.M.T. *
