What is a TENS Machine?

TENS  is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation although the term is often used with a more restrictive intent, namely to describe the kind of pulses produced by portable stimulators used to treat pain.The unit is usually connected to the skin using two or more electrodes. A typical battery-operated TENS unit is able to modulate pulse width, frequency and intensity. 


How does TENS (Transcutaneous Electrical Nerve Stimulation) work?

Electrode pads are placed precisely on or near the pain area. Pulses are sent from the TENS unit, through the pads to the skin. The pulses then travel along the nerve fibers, suppressing pain signals to the brain. TENS can also encourage the body to produce higher levels of Endorphins and Encephalins - the bodies natural pain killing chemicals.

What kind of painful conditions can TENS help?

Numerous painful conditions can be helped with TENS including:

  •  Back pain
  •  Sciatica
  •  Tension headaches and Migraines
  •  Whiplash
  •  Neck Pain
  •  Sports Injuries
  •  Arthritis
  •  Menstrual Pain (dysmenorrhea)
  •  Peripheral Nerve Injuries
  •  Shingles Pain
  •  Cancer Pain
  •  Trigeminal Neuralgia (TN)
  •  Phantom Limb Pain (PLP)
  •  Aching Joints
  •  Post-Operative Pain
  •  Muscle pain and related conditions


Are TENS units easy to use?

NueMedics TENS Units very easy. Step by step instructions are provided with every unit.


Is This Kind Of Treatment Safe?

Yes, TENS devices are tested and safe, and have no known side effects to be concerned about during or following usage. The idea of the electrical impulses entering your skin and muscle tissue might be alarming at first, but the treatment is not painful. In fact, most users of these devices compare the sensation that they experience to that of a vibration rather than any type of shock or electric energy. There are many different styles of TENS units and electrodes to choose from for your skin type and pain.


Can I share my TENS unit with others in the family?

Any of the  NueMedics TENS units can easily be shared with other family members. Please make sure that each person has their own set of Long Life Pads to prevent cross-contamination between individuals. To share the TENS unit, we recommend that each user have a separate electrode cord because the gel pads are connected.



Should I prepare the skin before using the electrodes?

The skin should be cleansed with soap & water or a damp cloth & dried before applying the electrodes to the area. This will also enhance the life of the electrode pads.



How long can I use the TENS EMS power muscle stimulator?

You can use it as often as you like. You can use it from 20 to 60 minutes each time, 2 to 3 times per day for better and faster improvement. There are NO chemicals or drugs or creams involved. It is very safe for long term use.


What are the differences between the modes?


All modes are pre-set and designed by healthcare professionals for specific body pains. For example, in the lower back mode, the electrical stimulation pattern was designed to treat the type of pain found in the larger muscles of the lower back.


Do I need to ask my doctor first about using this electrotherapy device?

This device is designed for your personal use and is not intended to replace any health professional care. 

When in doubt, we recommend that you consult with your doctor first.


Can I adjust the intensity?

Yes, you can adjust the intensity of A/B channels through the control units.


How long before I feel benefit from my TENS unit?

Pain relief should begin immediately. However some people need a little longer. It may also take time to find the best position for the electrodes.


How long does TENS pain relief last?

Some benefit for the entire day. Others need to repeat the treatment.


Where can I apply the adhesive electrode pads?

You can apply the adhesive electrode pads to anywhere on your body, except the heart and brain area, the front of the neck, or directly on an open or bleeding wound.


Should I buy a rechargeable device?

This is down to personal preference and available spend. A rechargeable machine is likely to command a greater initial investment but it’ll probably cost less to run over time.
