EDS – Electrodermal Screening


Koru has been providing mobile EDS services to patients of the Waterdown Clinic since 2002. Electrodermal screening is performed in our office by an experienced technician. The testing procedure is painless, quick and accurate.

Results of this testing will be reviewed with patients at their  next regularly scheduled appointment. In addition to food and environmental sensitivities, the results provide detailed information and complex patterns of information about the patient’s body and energy, which is integrated into the their overall treatment plan.

If you are not currently a patient of the Waterdown Clinic, you will be required to have your initial consultation prior to scheduling your EDS testing.

 

What is involved in Electrodermal Screening?

During EDS, a blunt, non-invasive electric probe is placed on the patient’s hands or feet at specific points. These points correspond to acupuncture points which are the beginning or end of energy meridians.

Energy transfers its signal through an acupuncture meridian to the nervous system. Minute electrical discharges from the acupuncture points are measured and indicate the condition of the body’s organs and systems.

What are the advantages of EDS over other types of testing?

EDS is painless, non-invasive, and accurate. Electrodermal screening allows up to 500 foods to be tested painlessly, quickly at a rate of about 200 per hour. EDS measures both histamine and non-histamine responses to substances which many tests are not able to do. Non-histamine responses are particularly important in food sensitivities, since many reactions are non-histamine related, such as bloating, fatigue and headaches.

How does the EDS equipment work?

Koru uses the Biomeridian BEST system. The system measures electrical resistance and polarization at acupuncture points and meridians. The basis of this technology was invented in the 1950′s by the German medical doctor Reinhold Voll. The equipment consists of a modern computer program, a sensitive Ohm meter and a signal generator.

There are two cables coming out of the signal generator; one is positive, and the other one is negative. The positive lead is attached to a stylus with an electrode tip. The technician holds the stylus by the insulated handle and presses the tip against one of the patient’s acupuncture points. The patient holds a hand electrode in their free hand. During the measurement, the patient and the EDS form a closed circuit, allowing energy and information to flow from the EDS to the probe, through the patient to the hand electrode, and back to the EDS unit.

The EDS reading is a measurement of how much energy makes it through the circuit. The lower the resistance is the higher the reading will be. EDS uses a scale of 0 to 100 with 45-55 being considered “normal” or “balanced”.

How can EDS data be used?

EDS data can help naturopaths detect and treat:

Are EDS results accurate?

Research published in the Journal of Naturopathic Medicine concluded that “electrical conductance data reviewed correspond with histological reports. In clinical practice, EDS instruments are useful as diagnostic supplements to blood test, radiographic imaging, and case histories. The integration of reliable and valid bioelectric medical instruments into the clinical setting augment the ability to rapidly evaluate tissues…Bioelectric medicine offers clinicians new quantitative methods for evaluating subtle electromagnetic changes in humans.”

Although relatively new to Canada, EDS is accepted and widely used in many other countries including Germany, France and England. Today’s testing equipment is the end product of a thirty year evolution of Dr. Reinhold Voll’s work that utilizes a modern computer program, a sensitive ohm meter and a signal generator.

How is EDS used for food and environmental sensitivity testing?

Dr. Roy Curtain was able to ‘map out’ the electromagnetic frequency of many foods, inhalants and other substances in our environment. This ‘electrical signature’ is stored in the signal generator and is output during testing in a binary code form. The frequency of the substance is output and a skin response to that signal is measured with the probe at the ‘allergy’ point along one of the meridians.
