FEATURES OF AUTONOMIC NERVOUS SYSTEM AND CEREBRAL NEURODYNAMICS STATE IN YOUNG PATIENTS WITH CHRONIC VERTEBROGENIC PAIN SYNDROMES

Abstract

The origin of vertebrogenic pain syndrome is associated with the irritation of the receptor apparatus in the area of affected vertebral−motor segments with the responses of the corresponding muscle groups. Taking into account the neurophysiological interrelation of emotional, autonomic functions, as well as the dependence of the threshold of perception of pain sensations on the functional state of nonspecific brain systems, we have assumed about the interrelation of vertebrogenic pain syndrome with a state of nonspecific one. In order to determine the features of vegetative regulation and cerebral neurodynamics, 128 young patients suffering from chronic vertebrogenic syndromes have been examined. Vegetative tone, reactivity and physical, mental and emotional activity, as well as a protocol based on the expert evaluation of autonomic disorders have been investigated in this study. All the patients have reported about the manifestations of autonomic dysfunction, manifested by psycho−vegetative syndrome, clinical signs of which were permanent disorders in the cardiovascular and muscular systems, as well as respiratory, thermoregulatory, gastrointestinal spheres, against which they developed and vestibular crises, syncopal states and lipotimia. Subjective autonomic−emotional manifestations in patients predominated the objective ones, that testified to the significant role of emotional disorders in the structure of the syndrome of autonomic dysfunction. Psychophysiological activation in young patients with chronic vertebrogenic pain syndromes in the vegetative sphere was manifested by the sympathetic orientation of autonomic functions according to the results of vegetative tests, and in the neurophysiological one the predominance of desynchronizing brain system was noted. Key words: autonomic dysfunction, chronic vertebrogenic pain syndromes, non−specific brain structures.
