Reducing motor evoked potential amplitude variability through normalization [PDF]

Frontiers in Psychiatry
BackgroundTranscranial Magnetic Stimulation (TMS) is used for in vivo assessment of human motor cortical excitability, with application of TMS pulses over the motor cortex resulting in muscle responses that can be recorded with electromyography (EMG) as ...

Enhancement of Intraoperative Transcranial Motor-evoked Potential Derivation with the Use of a Fibular Head Reference Electrode Placement Method in Spine Surgery [PDF]

Neurologia Medico-Chirurgica
Intraoperative transcranial motor-evoked potential recordings commonly utilize the belly tendon montage method; however, its reliability in large lower limb muscles such as the quadriceps femoris and hamstring muscles can be limited. We hypothesized that

What is the Predictive Value of Intraoperative Somatosensory-Evoked Potential Monitoring for Postoperative Neurological Deficit in Intramedullary Tumor Resection?

Journal of Spinal Surgery, 2023
The objective of this study is to determine the accuracy of somatosensory-evoked potential (SSEP) monitoring versus SSEP combined with motor-evoked potential monitoring (MEP) for predicting postoperative neurological deficits following intramedullary ...

Deciphering the Morphology of Motor Evoked Potentials [PDF]

Frontiers in Neuroinformatics, 2020
Motor Evoked Potentials (MEPs) are used to monitor disability progression in multiple sclerosis (MS). Their morphology plays an important role in this process. Currently, however, there is no clear definition of what constitutes a normal or abnormal morphology.

Utility of somatosensory and motor-evoked potentials in reflecting gross and fine motor functions after unilateral cervical spinal cord contusion injury

Neural Regeneration Research, 2021
Fine motor skills are thought to rely on the integrity of ascending sensory pathways in the spinal dorsal column as well as descending motor pathways that have a neocortical origin.

Identification of injury type using somatosensory and motor evoked potentials in a rat spinal cord injury model

Neural Regeneration Research, 2023
The spinal cord is at risk of injury during spinal surgery. If intraoperative spinal cord injury is identified early, irreversible impairment or loss of neurological function can be prevented.

A bispectral index guided comparative evaluation of dexmedetomidine as an adjuvant to propofol-based total intravenous anaesthesia in spine surgeries done under motor-evoked potential monitoring

Ain Shams Journal of Anesthesiology, 2023
Background The anaesthetic agents can affect the quality of motor-evoked potential intraoperatively as they inhibit synaptic transmission. Intravenous anaesthetics suppress motor-evoked potential lesser than inhalational agents, so total intravenous ...

Correlation of N30 somatosensory evoked potentials with spasticity and neurological function after stroke: A cross-sectional study

Journal of Rehabilitation Medicine, 2021
Objective: To test whether the presence of N30 somatosensory evoked potentials, generated from the supplementary motor area and premotor cortex, correlate with post-stroke spasticity, motor deficits, or motor recovery stage.

Intracortical and intercortical networks in patients after stroke: a concurrent TMS-EEG study

Journal of NeuroEngineering and Rehabilitation, 2023
Background Concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) recording provides information on both intracortical reorganization and networking, and that information could yield new insights into post-stroke ...

Predictive value of motor-evoked potentials for motor recovery in patients with hemiparesis secondary to acute ischemic stroke

Annals of Medicine, 2023
Background Motor recovery following a stroke is related to the initial stroke severity and corticospinal tract integrity. One of the outcomes representing corticospinal tract integrity is the motor evoked potential (MEP).
