Electrodermal screening itself is relatively safe, although people with implanted pacemakers should avoid electrical current. Let the practitioner know if you have a pacemaker.

Electrodermal 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 more sweat produces better electrical conduction. In the 1950s, a West German physician …

Electro-dermal screening is a galvanized skin response that measures the electrical resistance on the skin’s surface. The purpose is to detect energy imbalances along invisible lines of the body described by acupuncturists as meridians. The testing device sends a tiny electrical current, too small to be detected by the patient, through a probe. The patient may …
