El Escorial revisited: Revised criteria for the diagnosis of amyotrophic lateral sclerosis
The criteria described below represent the result of a three-day workshop, convened at Airlie Conference Center, Warrenton, Virginia on 2–4 April, 1998 by the World Federation of Neurology Research Committee on Motor Neuron Diseases, and are placed on the WFN ALS website.
Electrodiagnostic criteria for diagnosis of ALS
Changes in motor unit synchronization following central nervous lesions in man.
The results of the present study suggest that the branched common presynaptic inputs that generate motor unit synchronization are either of corticospinal tract origin or are intimately dependent on its function.
Multifocal motor neuropathy
Clinically, multifocal motor neuropathy is characterized by slowly progressive asymmetric distal weakness, generally affecting the upper limbs, and electrodiagnostic testing in MMN reveals partial motor conduction block (CB), defined as reduction in proximally stimulated muscle evoked response compared with the distally stimulated response in one or more nerves at sites away from potential points of nerve compression.
Slowed conduction in the pudendal nerves in idiopathic (neurogenic) faecal incontinence
The hypothesis that idiopathic (neurogenic) faecal incontinence is due to damage to the nerve supply of the pelvic floor musculature is supported.
Effect of vaginal delivery on the pelvic floor: A 5‐year follow‐up
Evidence is provided for the hypothesis that pudendal neuropathy due to vaginal delivery persists and may worsen with time and for the effect of childbirth on the pelvic floor striated sphincter musculature.
Molecular mechanisms and phenotypic variation in RYR1-related congenital myopathies.
The data represent the most extensive study of RYR1-related myopathies and indicate complex genotype-phenotype correlations associated with mutations differentially affecting assembly and function of the RyR1 calcium release channel.
