Is
there evidence that TENS is useful for pain relief?
As of today, there is no evidence that TENS does anything for people with chronic pain. There is not a single randomized blind study which has categorically shown that TENS works to decrease pain.
So for the time being TENS cannot be recommended for pain control. Some health care professionals who recommend these devices often have shares in these companies or are paid to give out positive reviews. The next time you get prescription for a TENS machine from a physician, go get a second opinion. Of course there will always be some who argue otherwise; for these non believers go read Cochrane reviews on this topic. Consumers should save their hard earned money for things that work and not on scam devices.
For those who hate medical jargon- in plain English- TENS is junk therapy.
