For many years, the only published criteria for the electrodiagnostic (EDX) recognition of amyotrophic lateral sclerosis (ALS) were those formulated by Lambert (1957; 1969). In 1990, different EDX guidelines were incorporated in the all-inclusive diagnostic criteria formulated by a subcommittee on ALS of the World Federation of Neurology, which met in El Escorial, Spain. Unfortunately, particularly in regard to the EDX requirements, the 'El Escorial criteria' have several flaws which compromise… 
An evaluation of neurophysiological criteria used in the diagnosis of motor neuron disease
TLDR
Accepting EMG evidence of fasciculations as evidence of acute denervation increases the diagnostic certainty of MND, and the new criteria allow earlier diagnosis of M ND without increasing the false-positive rate.
Electrodiagnostic approach to the patient with suspected motor neuron disease.

TLDR
The authors review the diagnostic criteria for ALS, enumerate the important differential diagnostic possibilities that emerge from a careful consideration of the clinical features, and comment on neuroimaging studies and laboratory tests employed in the diagnostic process.
Fasciculation potentials in amyotrophic lateral sclerosis and the diagnostic yield of the Awaji algorithm
TLDR
The Awaji algorithm has restored the value of fasciculation potentials in the diagnosis of amyotrophic lateral sclerosis and the diagnostic yield of this algorithm is lower than that of the R‐EEC.
Electrophysiologic diagnostics of very early stages of ALS.
TLDR
The key electrophysiologic phenomenon in the early diagnostics of ALS is finding the neurogenic lesions in clinically intact muscles—that is, finding the subclinical abnormalities.
Complex fasciculations and their origin in amyotrophic lateral sclerosis and Kennedy's disease
TLDR
Combined fasciculations are distinctive in ALS, and it is hypothesized that they are triggered by a supraspinal mechanism reflecting dysfunction of descending motor pathways.
Electrodiagnostic Evaluation of Motor Neuron Disorders
TLDR
Nerve conduction studies (NCS) and needle electromyography (EMG) are essential in the evaluation of suspected ALS and are primarily used to exclude any potentially treatable motor neuropathy that may mimic ALS.
Variation in the neurophysiological examination of amyotrophic lateral sclerosis in Europe
TLDR
The existence of two different examination approaches, one with quantitative EMG analyses and relatively few muscles studied, and one with more muscles studied using qualitative methods was clearly confirmed in the present study.
Sensitivity and specificity of the ‘Awaji’ electrodiagnostic criteria for amyotrophic lateral sclerosis: Retrospective comparison of the Awaji and revised El Escorial criteria for ALS
TLDR
The new criteria for ALS do not result in a loss of specificity and can potentially improve the sensitivity by 16%.
Needle electromyography of the frontalis muscle in patients with amyotrophic lateral sclerosis
TLDR
Examining the frontalis provides useful information in establishing the diagnosis of ALS by identifying clinically evident or subclinical abnormalities in the craniobulbar region.
EFNS task force on management of amyotrophic lateral sclerosis: guidelines for diagnosing and clinical care of patients and relatives
TLDR
Early diagnosis should be pursued and a number of investigations should be performed with high priority, and every effort should be made to maintain patient autonomy during the entire course of the disease.

Role of electromyography in amyotrophic lateral sclerosis
TLDR
It is revealed that a large proportion of patients with a clinical diagnosis of ALS fail to have classical findings on initial electrodiagnostic studies, and several caveats of electrodiagnostics testing in these patients are revealed.

AAEE minimonograph #32: The electrophysiologic examination in patients with radiculopathies
TLDR
The value and limitations of the various electrophysiologic procedures used in the diagnosis of radiculopathies are discussed, including motor and sensory nerve conduction studies, late responses, somatosensory evoked potentials, nerve root stimulation, and the needle electrode examination.

TLDR
Electromyographic diagnosis has hitherto depended on the demonstration of evidence of partial denervation confined to the muscles supplied by a particular motor nerve or one of its branches, but this method has certain practical disadvantages.
Electrophysiologic studies in the diagnosis and prognosis of motor neuron diseases.
TLDR
Combinations of needle electromyography, nerve conduction studies, and other techniques can not only confirm the diagnosis or identify the presence of unsuspected disease, but can also provide clues to the rate of progression and prognosis.
SITE OF ORIGIN OF FASCICULATIONS IN VOLUNTARY MUSCLE
TLDR
The increase of fasciculations produced by prostigmine and some of the observations reported on the effect of nerve root and peripheral nerve block cast doubt on the central origin of these involuntary movements.
The distribution and frequency of spontaneous fasciculations in motor neurone disease.
TLDR
The detection of fasciculations is more effective than that achieved by clinical examination and the relationship of the results to other electrodiagnostic features of motor neurone disease is briefly discussed.
Voluntary activation and fiber density of fasciculations in motor neuron disease
TLDR
Differences in the peripheral microanatomy of a number of fasciculation units not activated voluntarily may underlie ectopic impulse generation in the terminal axonal arborization, endplate zone, or muscle fibers of these units.
The origin of fasciculations in motoneuron disease
TLDR
The collision technique was used to determine the origin of distal fasciculations in 25 motor units from 9 patients with amyotrophic lateral sclerosis and 6 with other diseases involving motoneurons, and multiple sites of origin were found in 8 motor units.
Needle EMG of the tongue: motor unit action potential versus peak ratio analysis in limb and bulbar onset amyotrophic lateral sclerosis
TLDR
Subclinical involvement of the tongue was found in 20% of the patients with limb onset amyotrophic lateral sclerosis and could be more accurately assessed with MUAP analysis than with automatic EMG.
