ABSTRACT: The author presents the past, present, and possible future of the Electrodermal Screening System (EDSS), EDS Test (EDST), and EDS Device (EDSD), and relates them to procedures that preceded them: traditional acupuncture based on meridian theory and electro-acupuncture according to Voll. The author and others have produced a body of scientific data and literature that demonstrate efficacy of the EDSS and offers plausible mechanisms of action. Use of the EDSS and EDSD for diagnostic screening and their possible integration into a modern health care system are reported.


Safe and inexpensive diagnosis by skin level measurements may be superior to present imaging techniques which give limited information. An instrument is needed that can be expected to do this reliably and effectively (1), a role that is filled by the EDSD. Its acceptance will not come easily and requires adequate research evidence.

The EDST, is a testing process in which measurements are taken with the EDSD. Together they form the EDSS, a general term that stands for all the components. The device, the test procedure and the system are integrally related and cannot be separated. They must be understood together.

The EDSS is theoretically based upon bioenergy (chi) and traditional meridians which represent the paths of flow of this energy. The obvious way to prove that such energy exists is by using a device which measures it. This is what the EDSD can do. This article reviews the history, methodology and the current state of modern research in this field of investigation.
