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 ...

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 ...

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

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 ...

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 during interventional neuroradiology
Neuroradiology, 1988Following transcranial electrical cortex stimulation motor evoked potentials (MEP) were monitored in 4 patients during 2 angiographic examinations and 4 therapeutic embolization procedures. Changes of MEP were observed in all 4 patients. Temporary decrease of MEP amplitudes as found in two patients was not followed by any additional postoperative ...

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.

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 ...

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.).
