abstract：OBJECTIVE:Transcranial Motor Evoked Potentials (TcMEPs) are sometimes used during lumbar spine surgery in order to detect and prevent an intraoperative nerve root injury. Typically, a fixed stimulus is applied, and one monitors for changes in response amplitude from several myotomes. Increased stimulating voltage may o...
