Over the past three decades, the field of intraoperative neurophysiologic monitoring has evolved and matured, and monitoring during procedures such as resection of acoustic nerve tumors and correction of spinal…
Over the last three decades, ultrasound technology has evolved such that clinicians working in small laboratories can now use it to image nerve and muscle routinely. Growing evidence has established…
Tests of neuromuscular transmission are used most often to detect the abnormalities characteristic of myasthenia gravis. Although myasthenia is not a common disease, it is often included in the differential…
Brainstem auditory evoked potentials (BAEPs) are used in pediatrics to detect and measure hearing loss in children who cannot be tested behaviorally and to evaluate the auditory brainstem pathways in…
Averaged evoked potentials have been used widely to record the changes in electrical potential that occur within the nervous system in response to an external stimulus. For clinical purposes, the…
In recent years, both the general public and health-care professionals have become increasingly aware of the potential hazards of exposure to certain chemicals. At the same time, the introduction of…
The electrophysiologic evaluation of movement disorders is not used as widely as traditional electromyography (EMG) and nerve conduction studies, but it can contribute to clinical management. Physiologic analysis can be…
The development of sophisticated imaging techniques has had a great impact on the role of somatosensory evoked potentials (SEPs) in the clinical setting. Their role in the evaluation of most…
Until about 25 years ago, direct noninvasive investigation of conduction in central motor pathways was not possible. Transcranial magnetic stimulation (TMS) was first described by Barker and co-workers in 1985…
Examination of the sensory pathways is particularly difficult in infants and young children, and the recording of somatosensory evoked potentials (SEPs) is therefore important as a means of providing objective…
