Revolutionary neurostimulation devices

The Tennant Biomodulators® are revolutionary, portable, neurostimulation devices designed to treat patients from all walks of life suffering from all types of conditions. The Tennant Biomodulator® devices, developed by Dr. Jerry Tennant, contain unique frequencies to produce microcurrent, electrical impulses that are transmitted by electrodes in the device through the skin to interface with the body’s internal peripheral nervous system for the purpose of therapeutic intervention.

Dr. Tennant’s priority frequencies are designed help patients improve circulation, increase nerve stimulation and promote faster injury recovery, as well as reduce pain naturally by increasing body voltage with gentle, non-invasive, integrative treatments. These treatments help a wide range of user groups and related conditions which include: sports injuries, combat recovery, medical procedures and syndromes, senior and family ailments, pain-free dental procedures and non-invasive face lift treatments. In addition, the Tennant Biomodulator® can safely reduce pain and inflammation in small and large animals.

Tennant Biomodulator® PLUS & PRO Therapy

A clinically proven method to reduce pain using electrical stimulus. A non-invasive therapy indicated for the symptomatic relief from, and management of, chronic intractable pain and post-surgical and post-trauma acute pain.

The Tennant Biomodulator® PLUS is an advanced unit designed for long-lasting pain relief. The Biomodulator PLUS unit settings include four proprietary modes developed by Dr. Tennant. These modes include Assess, Ten-8™, Infinity™ and Automatic.

The Tennant Biomodulator® PRO is a professional grade device specifically designed for when deeper therapy penetration is needed and is recommended for serious, chronic conditions. The device includes biofeedback technology and Dr. Jerry Tennant’s proprietary frequencies, as well as, user control options and more than 60 pre-set modes.

Both devices require a prescription for home use.

Biofeedback and Neuromodulation Technology

The Biomodulator uses Biofeedback and Neuromodulation technology designed to stimulate the body’s natural release of nitric oxide, endorphins and neuropeptides into the blood stream, and increases ATP 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 energy the body can heal itself. Nitric oxide causes vascular dilation and thereby increases blood circulation. This is critical to wound healing, reduction of edema and treatment of diabetic neuropathy.

Healthcare Professionals

Many different types of Healthcare Professionals are integrating with great success non-pharmaceutical, non-invasive Tennant Biomodulator® technology in their practice to treat different types of pain and chronic conditions.

Physicians (neurologists, orthopedic surgeons, internists, chiropractors, naturopaths, homeopaths, podiatrists)

  • Pain associated with neuropathy from diabetes, cancer, fibromyalgia and other chronic conditions
  • Pain connected to carpel tunnel syndrome, back pain and chronic or acute pain related to repetitive stress injuries
  • Pain associated with injuries, including pain after surgery, orthopedic-related injuries, scar tissue build up, phantom pain and “weekend warrior” strain

Nurse Practitioners

  • Assist physicians with treatment protocols specific to an injury or chronic pain condition
  • Instruct patients how to use the prescribed device at home

Dentists and Orthodontists

  • Dental pain connected with tooth extractions, orthodontics and dental procedures (used outside the mouth along jaw line)
  • Relaxation of the neck, head and shoulders connected with chronic pain of the mouth and jaw
  • Faster recovery from oral surgery

Physical, Occupational Therapists and Athletic Trainers

  • Use in conjunction with acupuncture to analyze and stimulate meridian energy flow
  • To improve the results of massage therapy

Biomodulator technology

How does it work?

Tennant Biomodulator® devices contain unique frequency sets created by Dr. Jerry Tennant to produce microcurrent electrical impulses, which are transmitted by electrodes in the device through the skin to interface with the body’s internal peripheral nervous system for the purpose of therapeutic intervention.

System feedback is the system’s (in this case, 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 body. The body’s response can be measured with respect to a signal sent out from the instrument to initiate the loop. When a signal is emitted and penetrates deep into the tissue, the impedance of the tissue (analogous to resistance in DC circuits but dynamic in nature) modulates the next waveform. The degree of modulation is based upon the changes of impedance of skin as signals are applied. This sets up a constantly changing interactive bio-loop possessing non-repeating signals. Eventually the change in impedance diminishes in significance until a plateau occurs.

Why does it work?

The body is continually influenced by external stimuli, which it reacts to in a way that maintains internal balance, or homeostasis. Because these stimuli are infinitely variable, no two stimuli are experienced in the same way. However, if pathological signals are experienced as repetitive, the body adapts to them and fails to recognize it has a problem. Blocking the brain’s ability to know that tissue is degenerating and painful is the normal mechanism-of-action of pain medications, TENS devices, implanted pain blockers and other commonly used pain therapies.

The Tennant Biomodulator® modifies the pathological signal so the brain becomes aware of it, inputting electrical impulses, to increase voltage, that are never the same and cannot be adapted to, forcing the body to respond by making new cells. Central nervous system involvement is reintroduced by neuropeptides that alter the regulatory pathway, breaking the repetitive pathological cycle and allowing cellular and organ recovery. The result is pain disappears because of healing, not because the brain doesn’t know the area no longer hurts.

Tennant Biomodulator® waveforms of tissue

(1) first being treated

In air, there is no conductivity between the electrodes. The output signal waveform appears as shown.

(2) midway through treatment

The device immediately detects when the electrodes are placed on reactive tissue as shown.

The passing of the pulsed sinusoidal waveforms causes the electrical properties of the tissue to change resulting in changes in the next applied signal. Hence biofeedback.

(3) when tissue impedance diminishes and treatment stops

In Assess mode, the device will ‘Ring’ when it detects the optimum characteristics.

Tennant Biomodulator® technology measures this signal 24 million times per second to recognize this condition.
