The term “motor evoked potential” (MEP) commonly refers to the action potential elicited by non-invasive (magnetic) stimulation of the motor cortex through the scalp. MEPs can be recorded using surface electromyography from all skeletal muscles and are mediated by fast-conducting cortico-motoneuronal connections projecting monosynaptically to the alpha-

Motor evoked potentials (MEP) may be used in the diagnosis of central and peripheral neurological disorders and have become the standard of care in many operative procedures as a means to monitor the motor pathways.In the awake patient, transcranial magnetic stimulation (TMS) can be utilized with surface or subcutaneous muscle recordings to identify ...

Abstract Motor evoked potentials can be generated by either electrical or magnetic stimulation of the corticospinal pathways. Direct activation of pyramidal cells and indirect activation of cortical interneurons generate impulses that propagate down the spinal cord as D-waves and I-waves, ultimately stimulating anterior horn cells and ...

A comparison of somatosensory evoked and motor evoked potentials in stroke
Annals of Neurology, 1989AbstractNineteen patients with radiologically confirmed stroke, and varying degrees of hemiparesis, were studied using somatosensory evoked potentials and the recently developed technique of transcutaneous motor cortex stimulation. The functional deficit caused by stroke was assessed at the time of evoked potential testing and again on follow‐up 2 ...

Exploration of the Intraoperative Motor Evoked Potential
SPINE, 2016Prospective study.The objectives of the study was to (1) seek a relation between motor evoked potential (MEP) and corresponding cervical cord function in cervical compression myelopathy (CCM) and (2) explore a high-sensitive MEP range that can predict the intraoperative monitoring change ahead in cervical spine surgery.There have been lots of ...

Evoked potentials in motor system diseases
Neurology, 1988We studied pattern-shift visual (PSVEP), brainstem auditory (BAEP), and somatosensory (SEP) evoked potentials in 38 unselected patients with motor system diseases (MSD) (28 sporadic, 10 familial). PSVEPs were normal in all patients, and BAEPs were normal in all except one with clinical hearing loss who had absent waves I and III and prolonged wave V ...

Alarm criteria for motor evoked potentials
Neurology India, 2017To evaluate three commonly used alarm criteria for interpreting the significance and diagnostic value of transcranial motor evoked potential (TcMEP) changes during spinal surgery.A systematic literature search was performed using PubMed/MEDLINE, Web of Science, and EMBASE from 1945 to January 2014. We included all those studies that were (1) randomized

Transcranial Motor-Evoked Potentials
2011Motor-evoked potentials (MEPs) are the most recent addition to routine intraoperative neurophysiologic monitoring (IOM). Enthusiastic reports of improved outcomes obtained with the use of somatosenory evoked potential (SEP) monitoring, primarily for scoliosis procedures in children and young adults, were quickly followed by case reports of isolated ...

The diagnostic value of motor evoked potentials
Clinical Neurophysiology, 1999To assess the diagnostic usefulness of motor evoked potentials (MEPs) and to identify the optimal method for calculating the central conduction time. The test results were evaluated in a prospective study of 1023 neurological patients.We evaluated the correlation between clinical and electrophysiological findings, the accuracy, the sensitivity, the ...

Abstract This chapter focuses on motor evoked potentials (MEP). It cites how painless transcranial magnetic stimulation (TTMS) has generally replaced electric shock, gaining wide acceptance in the clinical study of MEP. In addition, magnetic stimulation can excite the motor roots in the region of the intervertebral foramina as well as ...
