title: [Diagnosis of syndromes of nervous system lesions from ratios of the voltage-time curves of central and motor responses of the muscles of the leg and foot].
abstract: The study was conducted in two age groups of normal subjects (adolescents and youths aged 16-21 years and 24-40 year-old adults) and in three groups of patients: (1) with alpha-pyramidal deficiency; (2) with gamma-pyramidal syndrome, and (3) with syndromes of damage to the peripheral nervous system and the segmental apparatus of the spinal cord. Each group of those studied was shown to be characterized by peculiar correlations of the voltage-time curves of the central and motor responses of the musculus soleus and the muscles of the sole to electrical stimulation of the tibial nerve. The correlation of these curves is suggested to be used as an electrophysiological index for the diagnosis of the subclinical forms of the above syndromes.
