[Hereditary motor and sensory neuropathy. I. Principles of classification and clinical picture].
The clinical picture was analysed in two types of hereditary motor-sensory neuropathy isolated on the ground of electrophysiological criteria. Type I comprised 34 patients with the conduction velocity in median nerve below 38 m/sec. Type II 19 patients with the conduction velocity above 38 m/sec. The age of onset was similar in both types and cases with onset below the age of 5 years prevailed. The assessment of the clinical picture using a acoring system failed to show any significant differences between type I and type II. Cases of type I shows, however, a considerable variability of the clinical picture and the course of disease process. Cases of type II were more homogeneous.
