History Behind Electro-Dermal Screening

History Behind Electro-Dermal Screening. 

Electro Dermal screening has its earliest roots in what was called galvanic skin testing. The galvanic skin response, a method of measuring the electrical resistance of the skin, was discovered in the early 1900s. Galvanic skin testing detects sweat on the skin, and the more sweat there is, the better the production of electrical conduction. History Behind Electro Dermal Screening.

In the 1950s, a West German physician and acupuncturist named Reinhold Voll combined acupuncture theory with galvanic skin response technology. He tested the skin along various points with particular attention to the acupuncture meridians. This is how galvanic skin response testing became known as Electro Dermal screening  Changes in galvanic skin response are still sometimes used in mental health research studies or to detect hot flashes in menopausal women. For most purposes, this method has been replaced with more advanced types of testing.  Galvanic skin response changes are still used in lie detector tests, along with several other measures such as pulse, breathing, and blood pressure.

History Behind Electro Dermal Screening.

The Vega story began in the 1950's when Dr. Voll, a doctor of orthodox medicine, studied a Chinese technique called Electro-Acupuncture (EAV).  This technique required an experienced practitioner to make a minimum of 700 electrical readings on acupuncture points before any conclusions could be drawn. Needless to say this was a very time consuming process.

Dr. Helmut Schimmel, who was a very capable user of the EAV technique himself, developed a shorter and less time consuming method in the sixties, measuring over only 150 points.  He named this new technique Bio-Feedback Diagnosis (BFD).

Dr. Schimmel manufactured his equipment under the name VEGA (manufacturers of high quality electronic measuring equipment) and further developed it in the early seventies under the name VEGA Resonance Test (VRT). With this technique the practitioner only uses one Acupuncture point and introduces different Homeopathic substances (Test Ampoules) into the measurement circuit, then simply reads the value on the display.  The benefits of this method are enormous - less time is needed for the testing process, giving far greater sensitivity and simpler operation.
