More Information

  • Contraindications:
    - Any electrode placement which applies current to the carotid (neck) region
    - Patients with implanted electronic devices (for example, a pacemaker) or metallic implants should not undergo TENS treatment without first consulting a physician
    - Any electrode placement which causes current to flow transcerebrally (through the head)
    - The use of unit whenever pain symptoms are undiagnosed and the etiology is unknown
  • What is TENS (Transcutaneous Electrical Nerve Stimulation) ?
    - TENS is a treatment whereby electrical impulses are applied to nerves through electrode pads placed on the skin
    - TENS is non-invasive and does not use pharmaceuticals
  • TENS uses a 2-pronged approach to pain relief:
    - First, sensory nerves are targeted, stimulating them to block pain signals and prevent their transmission to the brain
    - Second, TENS promotes the production of endorphins, ‚  eurochemicals occurring naturally in the brain which have analgesic properties


Pulse AmplitudeAdjustable, 80 mA peak maximum for positive pulse or -20 mA peak maximum for negative pulse into 500 ohm load each channel
Pulse rate(Adjustable) 2Hz to 120Hz
Pulse width(Adjustable) 40µ S to 260µ S
Modulation modePulse width is automatically varied in a cyclic pattern over an interval of nominally 5.0 seconds maximum. Pulse width decreases linearly
over a period of 1.5 seconds from the control setting value to a value which is decreased 45% maximum. The narrower pulse width will
continue for 2 seconds maximum, then increase linearly over a 1.5 second period to its original value. The cycle is then repeated.
Burst Mode:Bursts consist of 9 ±2 pulses at maximum pulse rate
Bursts occur twice every second
Wave formAsymmetrical Bi-Phasic
Maximum charge per pulse21 micro coulombs maximum. Positive pulse and negative pulse separate.
Battery9 volt battery (alkaline, or nickel-cadmium rechargeable).
Size23mm x 64mm x 91mm
Weight130grams (battery included)
