What is EPR Biofeedback? 

EPR (Electro-Physiological Reactivity) Biofeedback Devices measure reactivity and provides feedback which can be very educational to the client.  The results provide insight into an individual's overall stress profile. Typically biofeedback devices use EEG, EMG, ECG, EKG, HRV, TVEP and GSR.  Many of the devices you will find on this website use a combination of measurements and have special "feedback" functions which make our EPR Biofeedback Devices unique.

EPR Biofeedback retrains your body and mind to a better "reactivity" in a finely tuned way and reeducates muscles for stress reduction. Stress can come from many sources such as toxicity, trauma, pathogens, mental factors, perverse energy, allergies, heredity, habits, and deficiency syndrome. As acute and chronic forms of stress continue, the burden on the body/mind complex continues. Excess stress is a leading precursor to many diseases and conditions.

The Challenge of Purchasing Previously Owned Equipment

There are many used biofeedback devices being sold on the internet and by word of mouth.  If a biofeedback device is being sold, you must ask a few questions such as…Why are they selling it? Is something wrong with it? How do I know if it works correctly since it was in possession of someone who may not have used it properly or may not have taken proper care of it? How do I learn how to use it? Who will I call when I need technical support? These biofeedback devices are registered as Class II medical devices in the United States, so am I following the proper procedures for purchasing a medical device that has been registered with the FDA? Is the device a legitimate device and not a clone copy of the real thing?  Yes, these are all valid questions to ask when considering the purchase of previously owned medical equipment.

We have developed a system of testing and verification so that you can feel comfortable about your purchase of a previously owned biofeedback system. These are expensive devices that perform very important functions...they don’t ship out from our facility unless they are found to meet or exceed the manufacturer's original specifications for each device. All of our previously owned biofeedback devices go through the proper transfer of ownership procedures as set forth by the manufacturer of the device. We back this up with our own 1-year warranty on each device we sell.  The warranty covers manufacturing defects and failures that are covered under the original manufacturer's warranty when the device was new.


We offer an online biofeedback training course and detailed training manuals from the leading training academy in our industry. The online training certificates will expire 1 year from the date of purchase. We suggest that you begin your training within the first week after you purchase the system.

Payment Options

There are several payment options including the use of Credit Cards, PayPal, Bank Wire, Certified Check or Money Order. We also have financing options available.  We will ship your system in approximately 4-6 weeks from the time your payment processing has been completed, be sure to check each listing in our product store for complete details for each EPR Biofeedback Device System.
