Spine surgery breakthrough: new nerve monitoring method tested
NCT ID NCT02192112
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new method to monitor nerves during spine surgery for degenerative lumbar disc disease. Researchers used surface electrodes on the skin to stimulate nerves in the lower back and record muscle responses in the legs. The goal was to see if this approach is reliable and reproducible during surgery. 57 adults undergoing lateral spine surgery participated.
