Could a gentle zap to the spine ease chronic nerve pain?

This study tests whether a noninvasive electrical stimulation device placed on the skin over the spine can reduce pain and improve quality of life in people with neuropathic (nerve) pain. About 62 adults with chronic low back pain from nerve damage will receive either real or sham stimulation during their hospital stay, then be followed for 3 months. Researchers will measure pain levels, sleep, anxiety, and overall function to see if the treatment helps.
