[Diagnostic significance of indices of somatosensory evoked potentials in painful radicular and reflex syndromes in patients with osteochondrosis of the lumbar portion of the spine].

Forty patients with vertebrogenic painful syndromes related to radicular, muscular-tonic and neuro-dystrophic damage to the peripheral nervous system were examined for somatosensory evoked potentials of the projection zone of the cortex. The authors have shown changes in the latent periods of late components II180 and H225 depending on the nature of the syndrome and the possibility of the differential diagnosis of pain afferentation.
