The electrodiagnosis of Guillain-Barré syndrome subtypes: Where do we stand?
Clinical Neurophysiology, 2018It is controversial as to whether the electrophysiological Guillain-Barré syndrome (GBS) subtypes can be diagnosed on the basis of a single study and which criteria sets and cut-offs should be used.

Journal of Neurology, 1999
This review describes some of the factors that may lead to erroneous interpretations of electromyographic and nerve conduction studies. Such errors may be due either to technical or to biological factors, and it is imperative that the consequent limitations of the methods be considered in a diagnostic setting.

Electrodiagnosis of Radiculopathies
Neurologic Clinics, 1985Electrophysiology assesses function and should be considered complementary to, not as competing with, myelography, which assesses structure. Electromyography, being devoid of morbidity and significant side effects, should precede invasive radiology: myelography and contrast-enhanced computerized tomography (CT).

Nerve conduction normal values for electrodiagnosis in pediatric patients
Muscle and Nerve, 2019Existing normal value references for pediatric nerve conduction studies (NCS) are based on limited sample sizes with uncertain reliability, suggesting a need for better normative data.

Electrodiagnosis of Infantile Botulism
Journal of Child Neurology, 2000Analysis of the literature on the electrophysiologic features of infantile botulism was undertaken. Small compound muscle action potential amplitude is a very sensitive feature but lacks specificity. The decremental response to 2- to 3-Hz repetitive nerve stimulation is inconsistent and not a reliable sign.

Electrodiagnosis of Plexopathy
PM&R, 2013AbstractElectrodiagnostic evaluation of the brachial and lumbosacral plexus can be challenging even to an experienced practitioner. Detailed attention to anatomy and correlation with the history and physical examination results are needed to have a comprehensive differential diagnosis and to develop reliable conclusions.

Electrodiagnosis of Myotonic Disorders
Physical Medicine and Rehabilitation Clinics of North America, 2013Clinical and electrical myotonia is caused by a small group of neuromuscular disorders. This article reviews myotonia and its differential diagnosis. The use of electrodiagnostic testing to evaluate the primary myotonic disorders (myotonic dystrophy and the nondystrophic myotonias) is also discussed.

Electrodiagnosis of Plexopathies
Neurologic Clinics, 1985The pathophysiologic processes underlying plexus lesions and their recognition by electromyographic examination are detailed in this article. The nerve conduction studies most helpful for localization of plexopathies are discussed, and the electromyographic findings of the most commonly encountered plexopathies are described.

Electrodiagnosis in Neuromuscular Disease
Physical Medicine and Rehabilitation Clinics of North America, 2012Electromyography (EMG) is an important diagnostic tool for the assessment of individuals with various neuromuscular diseases. It should be an extension of a thorough history and physical examination. Some prototypical characteristics and findings of EMG and nerve conduction studies are discussed; however, a more thorough discussion can be found in the ...

Electrodiagnosis in Facial Palsy
Archives of Otolaryngology - Head and Neck Surgery, 1972Nerve excitability test, intensity-duration curve, and measurements of action potentials evoked by facial nerve stimulation (evoked electromyography) were made on 146 patients, ie, 117 with Bell's palsy, 14 with Ramsay Hunt's syndrome, and 15 with traumatic palsy. Surgical decompressions were performed on 34 patients.
