FREQUENCY SETS: the Tennant Biomodulator® PLUS includes advanced frequency sets that are unavailable in any other TENS or biofeedback type of device. Each mode is selected by pressing the mode-selector button. As you depress the MODE selector button, an LED illuminates beside each of these:

  • ASSESS: This setting is used to identify the best location for placement of the device on the skin. This mode works at localized areas of concern and "Bioterminals".
  • TEN-8: This pattern is very useful for focused areas of concern including muscle soreness.
  • TENNANT INFINITY™: This patent-pending frequency set delivers an infinite number of dynamically variable patterns to the body. No other device has this or any similar frequency set. Ideal for chronic pain and energy balancing.
  • TENNANT AUTO-INFINITY: Once the device is placed on the appropriate area, it begins an interactive bio-modulation protocol until the treatment cycle ends. Diodes allow the user to watch the process through the device's face plate graphical display. Both sound and visual output allows the operator to know the progress of the biofeedback process.

What is Interactive Feedback Electro-Stimulation Technology?

Tennant Biomodulator® PLUS  and PRO devices were developed as simple and easy-to-use, hand held devices for non-pharmaceutical pain relief.

These 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.

  • A precision medical instrument indicated in the use for symptomatic relief and management of chronic, intractable pain, and adjunctive treatment in the management of post-surgical and post-traumatic pain.
  • Treatment is gentle and easy
  • Non-invasive and drug free therapy
  • May be used as a complement to standard drug and therapy treatments provided by healthcare practitioners.
  • After treatment there are usually no physical limitations imposed. Normal activities may be resumed immediately.
  • May be used in combination with other treatments, subject to healthcare professional prescription and direction.
