What is TENS?

Other than using this unit for Electro Erotic Stimulation, Tens AA TENS Units are typically used to control chronic and acute pain including Rheumatoid and Osteo-arthritis, Back pain, Menstrual Pain, Labour Pain, Peripheral Nerve Injuries, Shingles, Headache and Migraine, Cancer Pain, Trigeminal Neuralgia, Phantom Limb Pain, Sports Injuries, Sciatica, Aching Joints, Post Operative Pain, Muscular Pain, Whiplash and Neck Injury and many other conditions. It is simple and easy to use. Four Electrode Pads are placed near or around the areas in pain. Because this TENS AA unit is Dual Channel, you can use 2 or all 4 Electrode Pads at the same time. You control the pulse width, pulse rate, and intensity and in just 20 minutes per day you will experience dramatic pain relief. So, not only do you get a toy, but it will also function to relieve other body aches too!!

Dual Channel TENS Unit Directions:

  • Place Electrodes on or around where you are experiencing pain
  • Change the batteries when needed
  • Vary the controls and settings (both the frequency and voltage)
  • Set the proper duration and intensity of the stimulation (which depends on the location and type of pain)
  • Follow instruction manual

Low Frequency: The lower frequencies, 2-5 Hz, are believed to cause the body to react. The reaction creates natural painkillers, or endorphins. The endorphins block the pain naturally and while popular, this isn't the usual method of using TENS.

High Frequency: For more intense pain, higher frequencies, 90-130 Hz, work to actually interrupt those pain signals being sent to the brain. This is the most common use for the machine and while you start slow, it's not uncommon to need to up the frequency to find the best block.


  • Long term effects of chronic electrical stimulation are unknown.
  • Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the carotid sinus reflex.
  • Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong to close the airway or cause difficulty in breathing.
  • Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias.
  • Stimulation should not be applied transcerebrally.
  • Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions.
  • Stimulation should not be applied over, or in proximity to, cancerous lesions.
