Pediatric electromyography

Symposium : Neurological Disorders-II


This review has pointed out the morphologic differences in the pediatric population and the special subset of disorders of this group that are important for EMG studies and diagnosis of muscle disorders in this population. The size of the patient coupled with the process of myelination means that normative values must be available for each age group. The disorders discussed are generally encountered first in the pediatric population. The electromyographer who sees pediatric cases, must be aware of these disorders. The most commonly observed disorders have been described briefly and the most important signs have been presented differentiating the various pediatric neuromuscular disorders.
