The diagnostic value of motor evoked potentials

Clinical Neurophysiology, 1999
To 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 ...

Motor Evoked Potentials

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

2020
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, 1970
Abstract 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, 1999
The 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

[Motor evoked potentials].

Presse medicale (Paris, France : 1983), 1993
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, 1998
Magnetic 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, 1983
Spinal 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, 2004
To 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 ...

Intraoperative Motor Evoked Potentials

American Journal of Electroneurodiagnostic Technology, 2001
ABSTRACT.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 ...
