How to use TENS

This is a general guide on how to use a TENS machine. Always follow the manufacturer’s specific instructions.

TENS machines are small and lightweight, so you can use them while 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 should not 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. Speak to your GP, physiotherapist or pharmacist if you have concerns. You may need to take a short break from using TENS. Special pads are available for people with allergies.
