Intraoperative neurophysiologic monitoring was performed in a patient by somatosensory evoked potential, motor evoked potential and free-running electromyography with intraoperative stimulation. It was verified that after decompression, there was an increase in the amplitude of motor evoked potential responses, showing an immediate improvement of the treated levels. Intraoperative neurophysiolo...

migraine is a neurologic disease, which often is associated with a unilateral headache. vestibular abnormalities are common in migraine. vestibular evoked myogenic potentials (vemps) assess otolith function in particular functional integrity of the saccule and the inferior vestibular nerve. we used vemp to evaluate if the migraine headache can affect vemp asymmetry parameters. a total of 25 pat...

TO THE EDITOR: Enoka and Duchateau (2) correctly call for caution when interpreting voluntary surface electromyography (sEMG) in terms of neural drive. If voluntary sEMG signals recorded during nonfatiguing isometric contractions depend on the number of motor units recruited, their firing rate, and their size (5), modeling found no direct association between neural drive and voluntary sEMG ampl...

Intraoperative neurophysiologic monitoring (IONM), including somatosensory evoked potential (SEP), and transcranial electric motor (MEP), had been utilized during brain or spine surgery to identify neurologic deficits. But some deficits, such as abulia, could not be detected through routine IONM. MEP SEP might monitor non-motor sensory lesions surgery. We experienced a 72-year-old case with an ...
