Electric nerve stimulation has shown to be unsuccessful in helping people with chronic lower back pain. CNN Health reports that, “Transcutaneous electric nerve stimulation, or TENS, is delivered using a small battery-operated generator connected to a set of electrodes. The generator, about the size of a BlackBerry, transmits a weak electric current through the electrodes, which are attached to the skin at the site of chronic pain or at other key points.”
This treatment is quite popular, but shows little evidence of actually working to relieve pain. Richard Dubinsky, MD, states that, “Physicians are advised against ordering TENS for patients with chronic low back pain since it is proven not to work.”
