[Interrelations between Electrodermal Activity and Internal Diseases]

The article deals with a new medical technhique for the assessment of autonomic regulation of internal systems and skin. We suggest investigating skin sympathetic nervous activity by the method of electrodermal testing of skin sympathetic reactions. It has been showed that current of 200-250 microamperes and 12 volts is optimal for testing the skin sympathetic responses in adult patients. We observed 12 groups of patients with various diseases and a control group of apparently healthy people. Each of the experimental groups consisted of people with severe or moderately severe pathology of a certain type of visceral system which caused significant functional or structural disorders in the tissue of some organ. The study carried out on distal extremities revealed 12 pairs of skin segments of vegetative support; we suggested a conception of vegetotome--a site of embryonic development of the autonomic nervous system, which provides single autonomic innervation of individual sections of meso-, ento- and ectoderm.
