[Features of vegetative regulation in occupational dorsopathies].

Based on spectral analysis of heart rhythm variability, studies covered changes in vegetative regulation in patients with occupational dorsopathies of cervical and lumbar regions. Findings are that 75% of patients with occupational dorsopathies have marked vegetative disorders - insufficient activity of sympathetic nervous system and drastic dominance of parasympathetic regulatory mechanisms due to pathologic vertebrogenous influences on peripheral vegetative structures. The most informative stress testing to reveal vegetative dysfunction in patients with occupational dorsopathies is flexion test. Individuals with occupational dorsopathies and dominant parasympathetic regulatory mechanisms have more severe prognosis due to more frequent severe degenerative and dystrophic spinal changes.
