MEP recordings are a safe and effective means of assessing conduction along the central and peripheral motor pathways in a variety of clinical settings. MEP is proven to be effective in monitoring central motor pathways that are at risk during surgical procedures and is finding usefulness in the diagnosis and prognosis of several central nervous system disorders such as multiple sclerosis, stroke, and spinal cord injury. The responses can be elicited by a variety of stimulation techniques using either magnetic or electrical stimulation to the cortex, spinal cord, or peripheral nerve. Recordings can be obtained from several structures including the spinal cord, peripheral nerve, or muscle dependent on the clinical application. The clinical neurophysiologist should have a basic understanding of the techniques as well as the potential physiologic and technical factors that need to be accounted for in the interpretation of these studies.
