Results of the carried-out comparative analysis of nerve conduction studies indicators of 78 patients with demyelinating polyneuropathy (40 patients with the chronic inflammatory demyelinating polyneuropathy (CIDP) and 38 with hereditary motor and sensory neuropathy (NMSN) of type 1). It is revealed that nerve conduction studies characteristics of CIDP and NMSN of type 1 have similar lines in connection with the similar mechanism of a pathogeny - demyelination. The distinctive characteristic is uniformity of distribution of demyelinationat NMSN of type 1 in the form of uniform reduction of motor nerve conduction velocity (NCV) and compound motor action potential in the majority of the lesion peripheral nerves of extremities and high correlation dependence of indicators of NCV on tibialis on a longitudinal axis and with NCV on n.medialis and amplitude indicators at stimulation of n.medialis at patients with NMSN of type 1; patients with CIDP have a high variability and a symmetry of defeat with existence of conduction blocks and high correlation communication of amplitude indicators at stimulation of n.tibialis in distal and proximal departments.
