"We often get called in when
regular medicine can't do
anything. That's when being
an organ mechanic is
a beautiful thing."

Electrodermal Screening

Our commitment to provide the highest level of care to our patients combines the most innovative technology and time-tested therapies which allows us to work towards optimal health and achieve successful results.

Electrodermal Screening (EDS)

Electrodermal Screening is a superior and highly innovative computerized instrumentation that measures the energetic aspects of the body using the acupuncture points. It is a non-invasive energetic evaluation using a galvanometer that measures the skin resistance and electrical potential on an acupuncture point.

Electrodermal Screening

The body is an electrical system with all 50 trillion plus cells governed largely by electrical differences occurring between individual cells and our external environment.

Modern Biophysics has shown that cells resonate at certain frequencies and have radio-like transmitting and receiving properties that allow cells to inter-communicate and control biological and chemical systems in the body.

As healthy harmonic cells resonate at a very different frequency to that of unhealthy cells, the doctors at CCVM use a specialized non-invasive form of electrical resonance testing known as electrodermal testing in order to identify possible cellular imbalances or stressors that may be affecting the body’s electrical system.

These stressors may include:

  • Addictions: to food, alcohol, chemicals, nicotine, emotion
  • Allergies/sensitivities: to healthy food, fats, sugars, alcohol, chemicals, heavy metals (mercury etc), environmental inhaled substances (pollens, grass, petrol etc.)
  • Asthma, Hay Fever, skin problems
  • Hormonal imbalances: Resulting in possible weight problems, menstrual and menopausal issues
  • Psycho-immunology: Illness and stressed conditions where the primary cause lies in some past emotional, mental or physical trauma that the person has never fully recovered from


Electrodermal testing has been used successfully in Europe since 1953, originating with the German Electro-Acupuncture technique as developed by Dr. Reinhold Voll (a German physician, acupuncturist and engineer). Dr. Voll established a clear connection between electro-acupuncture points and internal organs, functions and processes.

The procedure involves measuring potential differences (voltage) between a tip electrode held against an acupuncture point and a large surface electrode (hand electrode) held by the patient. The resultant resistance is then measured. The EAV test technique is founded on the theory of acupuncture. EAV has shown that acupuncture points bear a direct relationship to a specific anatomical structure or physiological function of the body. The doctors at CCVM will use the classical EAV testing with new computer technology.
