A Typical Session

The revolutionary INDIGO Biofeedback Device was created over a period of many years of research and development to combine holistic medicine with advanced quantum technology. INDIGO makes it possible to query the body for its most acute and chronic needs or stressors, convey this information to the client, and then attempt to balance or correct the stressors with focused energetic training.

The main premises of quantum biofeedback are that the body is electrical in nature, that it is innately intelligent, that it has the ability to heal itself if the right conditions or stimuli are provided, and that as the client becomes more aware of that which has been unknown to them, they can make changes to improve their wellness.


Classical biofeedback was developed in the late 1960s by pioneering researchers such as Hans Selye, incorporating techniques developed as early as the 1920s to reduce stress. It is a modality for stress reduction through greater awareness and control of the body and its functions. The main object has always been to teach the body how to return to a state of homeostasis or balance. Classical modalities include finger temperature regulation, GSR (galvanic skin response or measuring skin's electrical resistance), EMG (electromyography or muscle relaxation), and EEG (electroencephalography or brain wave pattern training).


An initial session with the INDIGO or EPFX/SCIO takes approximately 2 hours, which allows for the completion of the intake form as well as the Suppression and Obstruction to Cure or “SOC” panel, which identifies lifestyle issues and medical history and helps cue the biofeedback device to any particular risks for the client. It is an overall value calculated by the device to reflect the client's impediment to healing. The lower the score, the fewer impediments to healing. Once the SOC panel is completed, the client is connected to the selected device with a head harness and limb straps. The device is then calibrated and the test scan proceeds for about four minutes, measuring the resonance or response of the body to over 10,000 items (including minerals, vitamins, toxins, allergens, viruses, pathogens, organ functions, etc.).


When the test is complete, the practitioner reviews the highest risk items and begins to attempt correction of priority conditions. This process usually begins with the balancing of minerals, vitamins, and organs to better enable the body to begin healing. The more specialized therapies can then be utilized as appropriate and a strategy for future sessions can be developed in consultation with the client. 


Follow-up sessions are approximately one and a half hours and involve a review of the "SOC" panel to determine if there have been any lifestyle or symptom changes to report. Once this is accomplished, the session proceeds as before, continuing training according to the client's needs and the wellness plan established after the first session.


Petra Nicoll, LLC  is a fully mobile service, which means that in addition to operating from my Lake Oswego home, Petra can come to you and conduct each session in the comfort of your own home within the Greater Portland areas. Distance sessions can also be arranged.


The INDIGO and EPFX/SCIO devices are used worldwide by Doctors, Kinesiologists, Dentists, Veterinarians, Naturopaths, Chiropractors, Homoeopaths, Acupuncturists, Nutritionists, Psychologists, Hypnotherapists, Biofeedback Technicians, Massage Therapists, and many other professional practitioners. In addition, many people from all walks of life own and use Quantum Biofeedback Systems, depending on their own personal or professional needs.

Quantum Biofeedback has taken the concept of this feedback loop and added three new components: artificial intelligence, use of electrical frequency to measure and provide training and a completely holistic selection of modalities to deliver that training.


The INDIGO operates at biological speeds, broadcasting over 11,000 frequencies to the body, each associated with a different item (mineral, vitamin, toxin, organ, emotion, etc.), recording its reaction to each, and identifying both acute and chronic potential imbalances. Clients can then be provided information about the results and frequency training signals can be activated to attempt a balancing or harmonizing for items of concern. The INDIGO does not replace the care of your doctor or licensed healthcare providers. However, by reducing stress, which often causes or contributes to illness, it may help the body to begin healing itself naturally.


Reduce the stress, take the load off the body, assist it to better repair itself and give your body a voice. That is what Quantum Biofeedback is all about. 

Quantum Biofeedback equipment includes a laptop, the INDIGO, head harness, and limb straps.
