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.
