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 ...

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 ...

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

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 ...

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 ...

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 ...

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

Clinical applications of motor evoked potentials
Electroencephalography and Clinical Neurophysiology, 1998Magnetic stimulation of brain and spinal roots provides a non-invasive evaluation of nervous propagation as well as of motor cortex excitability in healthy subjects and in patients affected by neurological diseases (i.e. multiple sclerosis, stroke, Parkinson's disease, myelopathies etc.).

This chapter discusses motor evoked potentials (MEPs) recorded by transcranial electrical stimulation (TCES) and transcranial magnetic stimulation (TCMS). It describes anatomy of the central motor pathways and physiology of the D and I waves. Intraoperative monitoring of MEPs using TCES is now widely used for spinal cord and posterior fossa surgeries ...

Due to the motor evoked potentials recorded in limb muscles after transcranial and spinal magnetic stimulation, conduction in the central motor pathways can now be evaluated safely and painlessly in man. The central motor conduction time obtained includes the time required for transmission, along the fast pyramidal fibres, from the cortex to the spinal
