A new guideline issued by the AAN finds that transcutaneous electric nerve stimulation (TENS), a widely used pain therapy involving a portable device, is not recommended to treat chronic low-back pain pain that has persisted for 3 months or longer because research shows it is not effective. The guideline is published in the December 30 online issue of Neurology®.
The guideline also determined that TENS can be effective in treating diabetic nerve pain, also called diabetic neuropathy, but more and better research is needed to compare TENS to other treatments for this type of pain.
