Quick answer: TENS may provide temporary relief for some people, but it is not a cure. NICE advises against offering TENS for osteoarthritis because evidence of benefit is insufficient. Check your diagnosis and suitability with a healthcare professional before buying a machine.
Arthritis-specific TENS recommendations
“Arthritis” includes different conditions. NICE NG226 does not recommend TENS for osteoarthritis. The NHS rheumatoid arthritis treatment page describes it as an option that may help pain. Neither statement means it treats the underlying inflammatory disease or replaces prescribed care.
Use our osteoarthritis guide or rheumatoid arthritis guide to find the relevant pathway rather than applying one recommendation to every type of arthritis.
TENS safety and reasons to avoid it
The NHS TENS guide says not to use it if you have epilepsy or a pacemaker. During pregnancy, use it only if your doctor or midwife advises you to. Seek advice first if the cause of your pain is uncertain.
If a clinician advises a trial
Follow the machine's instructions and ask your clinician about pad placement. Start with the machine switched off when applying pads. Stimulation should feel like comfortable tingling, not pain. Stop and remove the pads if your skin becomes irritated.
A manufacturer's instructions contain additional restrictions. Do not infer that a short online guide covers every situation. Do not copy a pad arrangement from a photograph without checking that it is suitable for you.
Questions to take to your appointment

- If a trial is appropriate, what outcome would make it useful?
- When should I stop or seek further help?
Frequently asked questions
Will a TENS machine cure arthritis?
No. Temporary symptom relief does not establish that a treatment alters the disease.
Should I buy one for knee osteoarthritis?
Discuss your options first. NICE advises against offering TENS for osteoarthritis; a product advertisement does not override that recommendation.
Does this page recommend a device?
No. There is no product ranking or promise of relief.
