The word biofeedback was coined decades ago to describe laboratory procedures being used to train experimental research subjects to alter brain activity, blood pressure, heart rate, and other bodily functions that normally are not controlled voluntarily. This early research demonstrated that biofeedback can help in the treatment of many diseases and painful conditions. Some believe that biofeedback will one day make it possible to do away with drug treatments that often cause uncomfortable side effects in clients with high blood pressure and serious conditions.

Clinical biofeedback techniques that grew out of the early laboratory procedures are now widely used to treat an ever-growing list of conditions: migraine and other headaches, digestive system disorders, high and low blood pressure, cardiac arrhythmias, circulatory issues, epilepsy, paralysis/movement disorders, and many other maladies.

Specialists who provide a variety of forms of Biofeedback range from psychologists, medical doctors, dentists, chiropractors, internists, nurses, physical therapists, naturopaths, and veterinarians to energy medicine practitioners, Certified Biofeedback Specialists (CBS), and many others.

The Quantum Biofeedback Technology, now entering the third decade of its development journey, and leading the field of Bio-Energetic and Bio-Response measurement, is the accepted standard for the application of Quantum Biofeedback.
The Indigo System, is the latest and most state of the art technology, taking a multitude of different stress reduction programs, methods, and techniques, and merges them into a more simple - best overall - well rounded approach. Quantum Biofeedback, works through sixteen different electrical factors of the body, calculates combinations of impedance, amperage, voltage, capacitance, inductance, and resistance for Electro-Physiological Reactivity (The Xrroid Process). The body is indeed electric; therefore reactivity in the body can be measured electrically.

E-P Reactivity results are based upon the ability to establish a "Tri-Vector" connection for an energetic "3-Dimensional" view of the client's current reactions to over 10,000 different items. All accomplished completely independent of user influence to help avoid bias or error. The picture painted by the reactions may help to create a better understanding of the individual factors pertinent to lifestyle and wellness. Once established, the Quantum Biofeedback auto-focus program, designed to monitor a client's reactions, helps optimize the quality and quantity of the stress reduction results.

The techniques and methods of Quantum Biofeedback stress reduction include addressing areas those most typically affected by the stressors of "every-day living". Some examples of these methods and areas are the "tri-vector", "auto-meridian", "auto-frequency", "auto-color", "auto-spinal", "chakra", and brain wave pattern relaxation.
