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-

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 ...

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 ...

Iatrogenic injuries are an undesired consequence of surgery, yet iatrogenic injuries to the motor system are much more devastating to a patient’s quality of life than most injuries to the sensory system. Generally an injury to the spinal cord will be most likely be picked up by somatosensory evoked potentials (SSEPs), yet a focal injury to the anterior

Motor-evoked potentials: unusual findings
Clinical Neurophysiology, 1999The aims of this study were to present rare findings of motor evoked potentials (MEPs) in 3 patients with spastic paraparesis and to show that careful interpretation is indispensable in experiments done with very high intensity stimulation.The conduction along several segments of the descending tracts was studied by our previously published method in 3

Intraoperative Motor Evoked Potentials
American Journal of Electroneurodiagnostic Technology, 2001ABSTRACT.Motor impairment is among the most feared and devastating outcomes following major surgery. Traditionally, the “wake-up test” has been used for intraoperative evaluation of motor function, but is associated with a number of limitations such as its general crudeness, common anesthetic risks such as extubation and recall, inadequacy as a ...

Motor evoked potential(MEP)is the most widely used intraoperative neurophysiological monitoring measure. It includes cortical direct stimulation MEP(dMEP), which directly stimulates the primary motor cortex of the frontal lobe identified by short-latency somatosensory evoked potentials, and transcranial MEP(tcMEP), which involves high-current or high ...

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 ...

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
