Electro Physiological Feedback Xrroid

Electro Physiological Feedback Xrroid (EPFX) (/ˈzɪərɔɪd/),[1] also known as Quantum Xrroid Consciousness Interface (QXCI), is a so-called energy medicine device which claims to read the body’s reactivity to various frequencies and then send back other frequencies to make changes in the body.[1][2] It is manufactured and marketed by self-styled "Professor Bill Nelson," also known as Desiré Dubounet.[1] Nelson is currently operating in Hungary, a fugitive from the US following indictment on fraud charges connected to EPFX.[2]

Descriptions of the device in mainstream media note its high price tag ($20,000 US) and the improbable nature of the claims made for it.[3] It has reportedly been used to "treat" a variety of serious diseases including cancer. In one documented case, undiagnosed and untreated leukaemia resulted in the death of a patient.[4]

The website Quackwatch posted an analysis of the device by Stephen Barrett which concludes: "The Quantum Xrroid device is claimed to balance 'bio-energetic' forces that the scientific community does not recognize as real. It mainly reflects skin resistance (how easily low-voltage electric currents from the device pass through the skin), which is not related to the body's health."[5]

Imports to the US are now banned.[6]
