Tennant BioModulator

PEMF or Pulsed Electromagnetic Fields have been widely accepted for many years.  The literature shows they are useful for everything from pain to stimulation of stem cells.  A PubMed search for PEMF shows 464 publications about this subject wheseas a Google search for PEMF gives 493,000 results!


Micro current is current in millionths of an ampere. An ampere is a measure of the movement of electrons past a point. Microamperage current is the same kind of current your body produces on its own within each cell. This is current in millionths of an amp. It is very small; there is not enough current to stimulate sensory nerves so the current flow cannot be felt. You can tell it is running by watching the conductance meter on the machine. FDA has approved all microcurrent devices for sale in the category of TENS devices. TENS devices are for pain control only and deliver milliamperage current. ALL TENS devices carry the same warnings precautions and contraindications. Microcurrent devices deliver micro amperage current not milliamperage current but the warnings for the device are same because all microcurrent devices are approved in the category of TENS devices. http://www.frequencyspecific.com/faq.php


For example, the Tennant BioModulator® is a microcurrent device that has been accepted by the FDA as a Class II TENS device.  It is a Frequency Selective Microcurrent PEMF device with an imploding waveform.

FDA Statement

The Tennant Biomodulator®¹ and certain accessory electrodes are FDA listed by its distributor or manufacturer in these categories:

  • 21 CFR 882.5890 – Neurology transcutaneous electrical nerve stimulator for pain relief 

  • 21 CFR 882.5050 – Neurology biofeedback device 

Indications for use:

  • Symptomatic relief and management of chronic, intractable pain

  • Adjunctive treatment in the management of post-traumatic surgical and post-traumatic pain

  • Relaxation training and muscle relaxation

Any uses beyond those published by the FDA above cannot be discussed on this standard-of-care website.  For a better understanding of the role of voltage in health and disease, it is recommended that you read Healing is Voltage:  The Handbook and Healing is Voltage:  Cancer's On/Off Switches.

Tennant Biomodulator® - Microcurrent therapy that works!


Empowering everyone to reduce pain and improve health!

Are you in constant pain, low back, neck, hips, legs, feet, arms or hands? Do you suffer from headaches, insomnia or digestive issues? Would you like to reduce your pain and sleep medications and improve your health? Then read on because the Tennnant Biomodulaotor may be a solution to help you to take control of your pain and health!

Introduction of Tennant Biomodulator®


In 2005, Dr. Tennant introduced the Tennant Biomodulator® as a cost effective biofeedback microcurrent device with a new set of proprietary frequency combinations unlike any available before. The Biomodulator® has four advanced frequency combinations that are automatically set, simple to apply and not available in any other device - visit About us/Technology. The easy to use treatment modes allow the user or practitioner to operate the device more efficiently resulting in more effective therapy with improved outcomes.

Dr. Tennant is recognized as one of the top 25 Doctors in the USA. Dr. Mercola (NY Times bestselling author) recognizes this and features Dr. Tennant in his article How Body Voltage Dictates Health and Disease. To read this article and watch this interview with Dr. Tennant CLICK HERE


Microcurrent therapy gently whispers at the body to solicit a healing response. The device sends out a series of AC microcurrent (uA) signals through the skin and measures the response (cybernetic loop). Each signal is only sent out when a change in response to the previous signal is recorded in the electrical properties of the skin. Visible responses include reddening of the skin, numbness, stickiness (the device will have the feeling of being magnetically dragged), a change in the numerical readout and an increase in the electronic clattering of the device.


The Tennant Biomodulator® PLUS utilizes lightning fast processors and easy to read voltages with an assessment method which employs a series of LED lights.  The easy to read voltage graphic helps the user monitor the process and progress during the therapeutic session. Being similar in size and shape to a computer mouse makes it easily to self- treat any part of the body. It is portable, ergonomic, and economically priced. The Tennant Biomodulator® PRO 2.1 incorporates an LCD readout screen for accurate measurements has additional modes for the healthcare provider.

Microcurrent Technology

Tennant Biomodulator® Technology

What is Reactions Feedback Electro-Stimulation Technology?


This genre of alternating current (AC) cybernetic reactions technology was originally developed by Russian scientists and doctors to treat cosmonauts that were in space for long periods. Russian therapy SCENAR® Self Controlled Energo Neuro Adaptive Regulator was developed as an alternative means for promoting the body's own healing process. These TENS devices had been widely used in Russian hospitals since the early 1980's. Tennant Biomodulator® devices were further developed by Dr. Tennant as simple and easy-to-use hand held devices for non-pharmaceutical pain relief.

How the Tennant Biomodulator® technology works


The Biomodulator® uses Reactions and Neuromodulation technology designed to stimulate the body's natural release of  endorphins and neuropeptides into the blood stream, and increases ATP (voltage) in the cells. The Biomodulator works by giving the cells the energy they are lacking. When the cells are restored to their optimal level of voltage the body can heal itself. This is critical to wound healing, reduction of edema and treatment of diabetic neuropathy.


The devices produce very minute microcurrent electrical impulses, which are transmitted by electrodes, onboard the device, through the skin to interface with the body's internal peripheral nervous system for the purpose of a natural therapeutic intervention. The devices are controlled by a high performance microchip into which proprietary algorithms are embedded.

Biofeedback is the body's response to the stimulus, and the technology's ability to detect, measure, analyze and respond to the body. With each response, the electrical properties of the tissue change. The device detects the change and responds, resulting in the very next signal being modified. This is possible because of the development of modern high-speed microprocessors, which are able to establish a cybernetic loop between electronic instrument and living tissue. Dr. Tennent calls this Frequency Selective Microcurrent.
