title: [Classification of amyotrophic lateral sclerosis (clinico-electromyographic study)].
abstract: On the basis of the clinical electromyographic examination of 117 patients with lateral amyotrophic sclerosis, the relationship was ascertained between the manifestations of this illness and the primary localization of amyotrophies in the distal or proximal regions of the extremities. The first group was characterized by rapid generalization of the pathological process and by the presence of marked symptoms of the involvement of the segmento-nuclear motoneurons and the pyramidal tracts whilst the second group largely manifested impairment of the anterior cornual motor cells and the spinal localization of the process throughout the course of the disease. It is suggested that cervicothoracic and lumbosacral forms of the illness be subdivided into distinctive variants in relation to the primary localization of amyotrophies in the distal or proximal regions of the extremities.
