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 ...

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 ...

Motor performance and sensory-evoked potentials
Electroencephalography and Clinical Neurophysiology, 1970Abstract Averaged evoked potentials (EP) to tones were determined for fifteen subjects in three tasks which were designed to evaluate the effects of motor response, of withholding a response and of different response latencies. With the influence of eye movement minimized, it was found that the various deflections of the sensory EPs were affected ...

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

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

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.).

Evoked potentials from the motor tracts in humans
Neurosurgery, 1983Spinal cord monitoring during operation is of increasing importance in the prevention of injury. However, there is no direct monitor of the motor tracts available. We have reported a system using direct stimulation of the area overlying the motor tract between the intermediolateral sulcus and the dentate ligament in cats.

MOTOR EVOKED POTENTIAL MONITORING WITH SUPRATENTORIAL SURGERY
Neurosurgery, 2004To assess feasibility and clinical value of motor evoked potential (MEP) monitoring with surgery close to supratentorial motor areas and pathways.Functional mapping by somatosensory evoked potential phase reversal and continuous MEP recording after high-frequency repetitive electrical cortex stimulation was performed during 182 operations in 177 ...

No shinkei geka. Neurological surgery, 2023
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 ...

Masui. The Japanese journal of anesthesiology, 2006
Motor dysfunction following spinal surgery and thoracoabdominal aortic surgery remain as one of their devastating complications. Since the development of postoperative motor dysfunction can deteriorate quality of life of patients, the prevention of such complications is an important clinical challenge.
