The Most Epic EPR (Electro-Physiological-Reactivity) Biofeedback Device Ever Made

The EPX™ Device is the Latest Emanation of Bill Nelson’s / Desire Dubounet’s Original Invention


Work With Super Fast EPR Data Processing

EPR stands for "Electro Physiological Reactivity". Gain double-blind biofeedback stress reactivity testing to over 12,000 signatures of items from our world, while looking at overall body-electric parameters, all averaged out to show important profiles based on the individuality of every client or patient.

Together, these features will forever change the way you work

A Completely Different Way Of Looking At Wellness

Looking beyond molecular health parameters means embracing the intelligence of the "Body Electric". How does the innate intelligence of the Body Electric communicate? Through stress reactivity to precise electrical information. Both eu-stress (positive) and distress (negative) reactions can pave the way for understanding priorities that may be overlooked when working with strictly diagnostic approaches. Because stress reactivity is subjective, the uniqueness of every person unfolds in a way that is client or patient centered, opening up a more holistic and human connection that is deeply meaningful for both the operator and subject.

All embracing to see the invisible

One of the basics of QX World’s OMNIS software, is the use and linking of multiple known perspectives in holistic knowledge. These abstract views, grouping content windows that logically belong together, can then be used as one element, and as such be addressed during your energetic training. Perspectives can either be generated by the software or created by the user, depending on the user’s knowledge and/or on the objective of the training.


QX World’s OMNIS is the result of more than ten years of intensive R&D and many years of strong commitment to the health care industry. This solid expertise has developed into a highly reliable software that brings maximum uptime to your energetic visualization and therapy.

More powerful & efficiency

The powerful QX World OMNIS software will boost your operational efficiency and will save you many hours of precious time. Thanks to the system’s advanced capabilities and linking between different knowledge models, you no longer need to go dive deeply inside each holistic healthcare knowledge to generate and master all the information yourself. 

Long term support

QX World’s Software Care program assures that via 6-monthly version updates for the OMNIS software and with it the complete database system is kept secure, and new feature improvements are added to answer your evolving therapy needs.

Integrated modules

Biofeedback Interface Graphics (BIG)
Do you want to see how your device works in real time? Our Biofeedback Interface Graphics module is here exactly for that! Follow the reaction of your patient, the output of the device, the harness connection and valuable information taken simultaneously from the OMNIS, all at the same time. Using some of the methods of more traditional Biofeedback, the BIG can also help your patient gain balance, train themselves, master their reactions and be more in contact with their inner self and capabilities, all working together to activate the body’s ability to heal itself.
Walking the pathway to health becomes so much easier when clients can actually ‘see’ what needs fixing! Project visual enhancement with high quality videos during the OMNIS session! With the Body Viewer, you are literally able to offer your patients a 3D experience, using the combined effects of visualization and very specific guided imagery designed to aid the main session as light frequential treatment. A whole library of audio video material is at your fingertips, all amplified with a mix of vibrational, auditory and visual stimuli that will actively involve the client in the recovery process. The powers of guided imagery and positive reinforcement have tremendous effects on general wellbeing, or on a focused specific problem we want to address. The Body Viewer is in constant information exchange with the main OMNIS, auto focusing its subconscious choices using the results you obtain continuously during your session. You can make your own selections or run an automated flow of therapies that gets the most current information from the OMNIS!
Degen Scan
A Piggyback program that detects subtle energies and allows for the possibility to work on an existing condition, if known, to apply light entrainment. From user friendly design, multiple therapy threads, to scans focused on emotional versus physical causes, the Degen Scan has it all! Degen Scan is built on the same principle as Quantic Biofeedback, helping the therapist find the causes of dis-ease, work on eliminating the stress factors, and building the path back to health from there on.
Proprietary Dictionary
Contrary to what its name states, this OMNIS module is anything but your typical library function. Focused on health case, this is a sort of dictionary that translates a condition into multiple ways of natural medicine designed to address it and reduce the stress factors associated with it. Click on an item in the list and you are rewarded with a range of natural therapy and advice, from Chinese Oriental Acupuncture, Electroacupuncture, Behavioral Medicine to the more conservatory Medical Definition and Symptom Check. As it runs together with OMNIS and all the other modules, you then have the option to work on multiple issues at the same time and give your patient the best possible care.
Home Use
Intricate part of OMNIS, the Home Use module is “home” to your automated therapy base, quick and easy to use, one of the most favorite modules amongst our therapists. You can personalize a session on the spot, choosing from more than 25 therapy options, with individual timings and an overall progress view. Ideal for returning clients that want to work on specific items, an impromptu client drop by, or even a self-focused session. Outstanding results while being time efficient!
Complement your OMNIS Software with an additional program that uses the superpowers of Iridology. Working in perfect harmony with your OMNIS, you can simultaneously run the two programs together and use the Iridology to provide light piggyback treatment for an exhaustive range of stress factors. From acupuncture points to specific eye related complaints, the Iridology focuses on stress factors in the following area: Facial, Eye, Gyums, Dental, Quadrant Repair, Eye Hand Coordination, Sacred Geometry, General Anatomy and many more. As easy to use as you can imagine! Choose your point of therapy, double click and let your QUEX device carry out the ideal balancing protocols with the optimal intensity and strength.
Smart Report
The Smart Report is everything you ever needed for engaging with your patients and building up your practice! Session information is now simple, visual and captivating!
Smart Report PRO
Did you ever imagine a simple report function can turn out to be your must trusted advisor? Simple for you to use, yet exhaustive and complicated AI algorithms are working in the background to make sure you have the most comprehensive picture of your patient’s session summary. So much more than just bulks of data hard to sort through and interpret, our Smart Report shows you the most accurate results, analyzes trends of improvement, allows for incredible personalization and learns about your patients the more you use it. You will be able to go back in time and search for any item of interest, get an average of improvement of any area of interest in time, see how risks, matrix items, emotions etc. behave in time, see what areas you worked with most and how rectification improves and changes. And if that is not enough, it will also pinpoint issues you might have forgotten, drawing your attention to an item or category that appears in the highest risk areas, to make sure you are not missing any important health aspect related to your patient. Couple your therapist intuition, knowledge and experience with our AI, and you have a perfect match!
