What is the BioModulator® Plus?

The Tennant BioModulator® Plus stimulates the body at the cellular level through electrical impulses transmitted by electrodes in the device, restoring cellular metabolic activity in the area of treatment.

The Tennant BioModulator® PLUS is designed for deep stimulation for effective, long-lasting pain relief to help patients from all walks of life suffering from all types of conditions.

FDA-accepted, these devices have been proven to alleviate muscle, tendon, and ligament pain due to injury, arthritis, fibromyalgia, diabetic neuropathy, carpal tunnel, sports injuries, phantom limb pain and Parkinson’s disease, just to name a few. 

Backed by science.

Dr. Tennant has dedicated his life to using his Tennant Devices to help his patients get well, and he has the clinical studies to prove it.

"One of my primary missions is to research and share my findings and enable others to educate themselves and discover answers to their unique health-related questions through wellness.” – Dr. Jerry Tennant

How does the BioModulator® Plus work?

The BioModulator® PLUS unit settings include four proprietary modes developed by Dr. Tennant. These modes include Assess, Ten-8™, Infinity™ and Automatic. This is Dr. Tennant’s original device and has been used by thousands of professionals and personal applications for over 14 years.

Unlike a traditional TENS unit that emits square waves without any true focus of energy, the BioModulator® emits curved waves to a targeted area which resonate better with the body. Oftentimes it takes longer to get results with square waves.

The BioModulator® has the capability of delivering these curved frequencies to the cells by first measuring the tissue through reaction and figuring out exactly what it needs. That way when the proprietary frequency developed by Dr. Tennant is introduced to a cell, it is measured perfectly for efficient healing. If the current was off by even a millionth of an amp, it can be the difference between the cells utilizing it or not.

What are the benefits of BioModulator® Therapy?

Benefits of home therapy with the BioModulator® Plus include…
– Gentle
– Easy to use
– Drug-free and non-invasive therapy
– Positive effects may appear after the first session
– May be used together with a standard drug or surgical treatment (adjunctive therapy)
– Helps decrease use of large doses of drugs
– Can help several conditions at the same time

The Tennant BioModulator® Plus offers a non-invasive, drug-free alternative, integrative or adjunctive medical treatment. It is painless. Treatment is conducted by placing the device directly on the skin or by using accessory electrodes that are available for purchase.

What’s the difference between a TENS Unit (Transcutaneous Electrical Nerve Stimulator) & a Tennant BioModulator®?

The Transcutaneous Electrical Nerve Stimulator, more commonly referred to as a TENS unit is an electronic medical device that produces electrical signals used to stimulate nerves through unbroken skin. The TENS units are bombardment devices; meaning they are not capable of “knowing” or delivering the exact current that the cell(s) need. The BioModulator® has the capability of delivering current “frequency” to the cell(s) by first measuring the tissue through reaction. When current is introduced to a cell, if it is off even a millionth of an amp, can be the difference between the cells utilizing it or not.

What does the BioModulator® Therapy feel like? Is it safe?

As the device moves over the surface of the skin, the patient feels a tingling prickly sensation. Patients usually report that they experience an immediate reduction in pain and feel “energized” after a therapy session.

Additionally, the Tennant BioModulator® Plus has shown little to no side effects. Training will provide you with the opportunity to receive maximum benefits.

DO NOT use on a person with a pacemaker or other electronic implants. See Safety Precautions.

How do I use the Tennant BioModulator® Plus?

Treat your BioModulator® Plus like a mini-computer, do not drop it or expose it to water, and store it unplugged in a case when not in use. AA batteries are used to power the BioModulator® Plus and should be changed regularly to avoid corrosion. You can access the battery compartment on the back of the device by sliding off the plastic door.

Available Modes on the PLUS

The illuminated BLUE light indicates the active mode. Each time you press the MODE button, the illuminated blue light will move to the selected mode.

Assess Mode – “voltmeter”. Reads the voltage when placed on the skin. This is used to measure specific points on the body. Place the metal contact of the device on the skin to be measured. A single light will illuminate to indicate if voltage is normal, healing or low. Device must remain still. Once the light is visible, the device can be moved to assess another area.

Ten-8™ – A therapy mode specifically developed for relief of chronic, intractable pain and for muscle and bone. Device does not have to be stationary; it can glide over areas of concern. This mode does not read voltage. The sensation felt in Ten-8™ is consistent in intensity. The colored lights are indicating power level.

Infinity™ – A treatment mode designed for symptomatic relief of pain and for organs. Device does not have to be stationary; can glide over the area of concern. This mode does not read voltage. The sensation felt in Infinity™ starts out low then it increases. It goes from low to high in intensity. The colored lights are indicating power level.

Automatic – This is a two-phase mode: (1) Reads your voltage and then (2) Infinity™ therapy mode begins automatically and continues 1 minute. A series of beeps sound when therapy session ends. It will then take another reading, so you can see if there was any improvement. Either move and treat another location or remain stationary for the next treatment cycle. Use Automatic when you want to measure the voltage and immediately treat.

Power Settings

Adjusting the Power Levels – Press & hold the UP (+) button to Increase Power (push and hold down the button to control power). Press & hold the DOWN (-) button to decrease power (push or hold down the button to control power).

NOTE: Device indicates power level when in Ten-8™ or Infinity™ modes only. When in Assess or Automatic the device is indicating a voltage reading

When in Ten-8™ or Infinity™ the lights on the curve will illuminate as the power of the unit is increased. As the “+” button is pressed and held, the lights will start to flash, then go solid, and the next light in line will begin to flash as the power increases. The lights will continue to illuminate in order, from left to right. Once at maximum power, the last light on the curve will be solid orange (10 power).

Avoid Measuring Voltage When…

• The skin is hot and sweaty 

• The skin is very dry 

• You have not had at least 8oz. of water to drink in the last 30 min. 

If you take readings under these conditions, they will not be accurate 

• If the skin is too dry the reading will be lower 

• If the skin is sweaty the reading will be higher

How do I take care of my BioModulator® Plus?

– Don’t turn on if below freezing.
– Clean electrode only with a 70% isopropyl alcohol .
– Do not leave your device in a hot car in the summertime.
– Do not try to open your device; doing so will void your warranty.
– Electrode corrosion can occur If not cleaned regularly.
– Device can be damaged to the point of non-function if dropped on
– hard surface. (a protective carrying case is recommended)
– Device WILL be damaged beyond repair if dropped in water or liquids are spilled inside.
– The battery compartment slides off and on the device. Do not force the battery cover.
– Be careful when accessories are plugged into the port. Damage can occur inside the port if there is too much movement at the plug.
– Always unplug wires from the accessory port and store device in protective case.

What is Dr. Tennant's Daily Protocol?

NOTE: You must have a BioModulator® device to complete this protocol.

This daily protocol will help balance and prepare your body so it can properly receive and use the voltage provided by your BioModulator® device for healing. This is accomplished by waking up and “activating” your organ systems, resetting your polarity so electrons flow correctly, balancing your autonomic nervous system, and recharging your whole body.
