How does a TENS device work and how do you use it correctly?

How it works

The machine uses electrical pulses to relieve pain. It transmits small electrical pulses through the skin which can block pain receptors to suppress pain signals in the nerve fibres and reduce pain. Pain is alleviated by the suppression of pain signals in the nerve fibres, among other mechanisms. This is especially true of high-frequency pulses. At the same time, the release of the body’s own endorphins is increased, whereby these factors reduce the sensation of pain due to their effects within the central nervous system. The method has been scientifically substantiated and approved as a form of medical treatment.

How do you use a TENS machine?

The first step is to always read the instructions carefully. Not only will this make the device easier to use but you’ll also be sure you’re getting the most from your TENS machine.

Then carefully apply the gel pads to the electrodes and cautiously remove the protective film. Ensure that the edge of the gel pad does not protrude over the electrode. Gel pads that are not applied flush on the electrode do not impact on their functionality.

Then position the electrodes on the affected area on the body and switch on the device. The electrodes should be placed on clean and dry skin. Avoid placing them on open wounds or scars. Finally, make sure that the electrodes are positioned correctly.

Now, select a program and start the treatment. Adjust the intensity to a comfortable level. The intensity can be adjusted depending on how much pain you are feeling.

Important! It’s always best to discuss TENS treatment with your GP or health professional. Not only can they confirm TENS is the right treatment for you, but they may also be able to advise you on the best way to use a TENS machine to suit your pain condition.

Placement of the electrodes

Important to the success of TENS pain therapy is electrode placement. You’ll often find a positioning guide in the instruction manual, or your TENS machine may have an on-screen positioning guide. If you feel unsure at all, your GP or health professional will be able to help.
