This Week - T : TENS (TE Nerve Stimulation)

Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current.

A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes.

You attach the pads directly to your skin. When the machine is switched on, small electrical impulses are delivered to the affected area of your body, which you feel as a tingling sensation.

The electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles. They may also stimulate the production of endorphins, which are the body's natural painkillers.

What TENS is used for

TENS may be able to help reduce pain and muscle spasms caused by a wide range of conditions including:

Does TENS work?

There isn't enough good-quality scientific evidence to say for sure whether TENS is a reliable method of pain relief. More research is needed and clinical trials for TENS are ongoing.

Healthcare professionals have reported that it seems to help some people, although how well it works depends on the individual and the condition being treated.

TENS isn't a cure for pain and often only provides short-term relief while the TENS machine is being used.

However, the treatment is generally very safe and you may feel it's worth trying instead of, or in addition to, the usual medical treatments.

Trying TENS

If you're thinking about trying TENS, it's a good idea to speak to your GP about a referral to a physiotherapist or pain clinic.

A physiotherapist or pain specialist may be able to loan you a TENS machine for a short period if they think it could help.

You can choose to buy your own TENS machine without getting medical advice, but it's generally better to have a proper assessment first, so you can find out whether a TENS machine is appropriate for you and be taught how to use it properly.

To get the most benefit from TENS, it's important that the settings are adjusted correctly for you and your individual condition.

If you find TENS effective, you can buy a TENS machine from a pharmacy. They range in price from about £10 to £200. More expensive machines aren't necessarily any better than lower-priced ones, so it's best to do some research before you buy.

How to use TENS

The information below is a general guide on how to use a TENS machine. You should always follow the manufacturer's specific instructions.

TENS machines are small and lightweight, so you can use them while you're working or on the move. You can put it in your pocket, clip it to your belt or hold it in your hand.

You can use TENS throughout the day for as long as you like, although it shouldn't be used while you're driving, operating machinery, or in the bath or shower. 

Positioning the pads

Make sure the machine is switched off before you attach the pads to your skin. Position the pads either side of the painful area, at least 2.5cm (1 inch) apart.

Never place the pads over:

  • the front or sides of your neck
  • your temples
  • your mouth or eyes
  • your chest and upper back at the same time
  • irritated, infected or broken skin
  • varicose veins 
  • numb areas

Turning it on and adjusting the strength

Turn on the TENS machine when the pads are attached in the correct places. You'll feel a slight tingling sensation pass through your skin.

The machine has a dial that allows you to control the strength of the electrical impulses.

Start on a low setting and gradually increase it until the sensation feels strong but comfortable. If the tingling sensation starts to feel painful or uncomfortable, reduce it slightly.

Switch the TENS machine off after you've finished using it and remove the electrodes from your skin.

Are there any risks of side effects?

For most people, TENS is a safe treatment with no side effects.

Some people may be allergic to the pads and their skin may become red and irritated, but special pads for people with allergies are available.

TENS isn't safe for everyone to use. Don't use it without first seeking medical advice if:

  • you have a pacemaker or another type of electrical or metal implant in your body
  • you have epilepsy or a heart problem
We'll have more information and advice next week on another topic in our A to Z of Gay Health. We have covered many subjects in this series and you can catch up with all of our Previous A to Z Features.
