Best TENS machine 2023: The best nerve stimulator machines to ease sciatica, labour and muscle pain

If you suffer with chronic muscle pain, especially in the back, shoulders or knee joints, the best TENS machine could be a life-changer. The best TENS machines, which gently stimulate the muscles to ease cramps and pain, are also a great drug-free way to ease the pain of labour, sports injuries, painful periods, sciatica and other chronic muscle discomfort.

TENS (which stands for transcutaneous electrical nerve stimulation) machines work by sending electrical pulses across the surface of the skin to block pain. It’s a non-invasive way to manage pain, but as with all medical treatments, it’s best to discuss the use of a TENS machine with your GP before you buy. Your doctor may be able to recommend a particular machine for your condition, or even let you hire one to test it out.

Check our recommendations below to find the best TENS machine to suit your needs. Not sure what to look for? Read on for our buying guide.

How to choose the best TENS machine for you

How does a TENS machine work?

TENS devices have a number of electrode pads, which you attach to the skin. Then the machine emits an electronic pulse to stimulate the nerves and block pain. It’s not painful, but it does produce a noticeable tingling sensation. This sensation is thought to play a role in preventing the nerves from sending pain signals to the brain.

The most common TENS programmes use high-frequency stimulation. This has been proven to help with acute and chronic pain. High-frequency stimulation sends impulses to the nervous system’s own pain-inhibiting mechanisms, which block the pain. Although these treatments are safe to use for long periods, it is recommended treatments shouldn’t last longer than 90 minutes.

Some of the TENS machines in our list also offer what’s known as EMS, which stands for electrical muscle stimulation. Various types of electrical impulses are sent to the muscles, depending on the programme selected. These signals make the muscles contract to retrain them, increase their effectiveness and improve their condition. It’s a particularly popular training and rehabilitation technique in sports.

What kinds of physical condition is a TENS machine suitable for?

TENS machines are most often used by people with chronic musculoskeletal pain – most often back and shoulder pain – or women in pregnancy. Patients with conditions including carpal tunnel syndrome (from arthritis or repetitive strain), low back pain, shoulder impingement and inflammation, and chronic jaw pain have reported benefits from using a TENS machine. Knee joint pain is another common condition improved with TENS stimulation.

Some TENS machines are marketed for use in labour and childbirth as a drug-free alternative to pain relief, although there are limits to the pain relief that TENS can achieve in this situation.

When should I not use a TENS machine?

In general, TENS machines are a safe method of pain relief when used as prescribed; however, there are a few situations in which they should not be used. As TENS machines use electrical signals that can interfere with other electric devices, they are best avoided by patients with pacemakers. TENS machines should not be used on the head, eyes or the front of the neck; the electrode pads should also not be applied on broken skin, or used over a tumour. If you’re unsure, check with your GP before use and always follow the supplied directions.
