Electrodermal testing is a bogus procedure where measurements of skin conductance with a biofeedback device are entered into a computer to diagnose nonexistent health problems and “energy imbalances” and to recommend treatments for them, often involving the sale of homeopathic remedies and other useless products. It falls under the general category of EAV (Electro Acupuncture of Voll). The history and variants of EAV are explained in an article on Quackwatch.
I’ve written about electrodermal testing before. I’ve explained how it amounts to fooling patients with a computerized Magic 8 Ball and I’ve discussed the legal and regulatory issues.
Now Stephen Barrett (founder of Quackwatch and Vice-President of the Institute for Science in Medicine) has written an article in FACT (Focus on Alternative and Complementary Therapies) entitled “Bogus electrodermal testing devices: where are the regulators?” He points out that existing regulations are sufficient to ban these devices, but that regulators have failed to take appropriate action.
AllergiCare Relief Centers are a chain of franchises started by a man called David Tucker who is not listed as having an MD or any other title. They offer diagnosis of allergies by biofeedback and treatment of allergies by laser acupuncture. They admit that the method is not backed by any science, and they claim that what they are doing is not medical treatment.
Responsible journalism might have investigated this as quackery or practicing medicine without a license. Instead, irresponsible journalism has helped promote these centers and has given them invaluable free advertising.
From one news story:
Tucker said the device works based on biofeedback. The allergy sufferer wears a sensing clip on his finger for testing, and the computer simulates the bio-frequency for 10,000 known allergens. As the body responds to those stimuli, the computer lists which substances are irritants. “This digitized allergen actually matches the harmonic frequency of the actual allergen, making the body believe it is in contact with the real substance,” Tucker said. “The body will react if it is allergic to the particular substance.” ….Once the allergens are identified, a laser stimulates biomeridian points on the body — the same points used in acupuncture and acupressure. Tucker said the idea is to strengthen organs to act properly the next time they encounter the allergen — that is, to treat them as harmless…So far, there is no science to prove the devices work, but Tucker claims a 70 percent positive response rate.
