Motor conduction velocity (MCV) of 15 children with spinal muscular atrophy has been reported. The high incidence of MCV reduction is demonstrated in the severe forms (Werdnig-Hoffmann) of the disease. The MCV decreases progressively with the muscular impairment, which seems to be confirmed by serial controls given in succession over a period of time. Of intermediate forms only one patient had a decrease in MCV. These results confirm the existence of two different types of the disease genetically determined. The authors suggest the importance of using this examination in serial controls for a better diagnosis and prognosis.
