How Transcutaneous Electrical Nerve Stimulation works:

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drugfree method of controlling pain. TENS Units use tiny electrical impulses sent through the skin to nerves to modify your pain perception. In most people it is effective in reducing or eliminating the pain, allowing for a return to normal activity. In many people, the reduction or elimination of pain lasts longer than the actual period of stimulation (sometimes as much as three to four times longer). In others, pain is modified while stimulation actually occurs.Unit overrides the pain signal to the brain by sending a comfortable electronic impulse. When the TENS Unit overrides the pain signal, it "tricks" the brain into thinking their is NO PAIN. This produces Fast and Rapid Pain Relief, usually within a minute or two. You can control and customize the intensity, pulse rate, and pulse width to "experiment" and find the best setting for your pain relief.

  • Channels: Dual, isolated between channels
  • Wave Form: Modified square with zero net direct current (DC) component
  • Pulse Amplified: Constant current 0 to 80 mA each channel, adjustable (500 ohm)
  • Pulse Frequency: 2Hz to 50Hz adjustable
  • Modulation Mode: Pulse width is automatically varied in a cycle pattern over an interval of nominally 4.0 seconds
  • Burst Mode: 9 +/- pulses at maximum pulse rate twice every second
  • Maximum Charge: 20 micro coulombs per pulse
  • Power Source: 9v alkaline battery or similar rechargeable cell
  • Size: 23 x 64 x 91 mm
  • Weight: 130 grams (including battery)
