A 2013 analysis published in Osteoarthritis and Cartilage found that PES improved knee OA pain and reduced the need for NSAIDs, but the studies weren’t well designed. How well it works: Research on PES for arthritis has been mixed. In theory, it treats arthritis damage by rebuilding and repairing joint cartilage. What it is: PES delivers a current to the site of pain via electrodes placed on the skin. It’s estimated that overall, about half of people who try TENS get a 50 percent reduction in pain. A 2015 Cochrane Review concluded, “ tentative evidence that TENS reduces pain intensity over and above that seen with placebo. TENS has been shown to relieve osteoarthritis (OA) pain and reduce the need for pain medications. How well it works: TENS helps acute (short-term) and chronic (long-term) pain. Many TENS devices have a controller that lets you pick the frequency you prefer. TENS can be delivered at low frequency (l-TENS) or high frequency (h-TENS). Another way TENS may relieve pain is by triggering the release of natural painkillers (endorphins) in the brain. It sends an electric current to your nerves to override pain signals. What it is: TENS uses sticky electrode patches attached to a small, battery-operated device. Transcutaneous Electrical Nerve Stimulation (TENS) So it’s important to talk with your doctor first if you have a pacemaker, another implanted device, are pregnant, have epilepsy, or have a heart problem. However, they involve sending electrical impulses though your body. In some people, neuromodulation treatments can ease pain with minimal risks and offer an alternative to medication for treating arthritis pain.
Nerve stimulation – or neuromodulation – uses electricity to decrease pain sensations.
