[Electroneurophysiologic studies of patients with reflex syndromes of cervical osteochondrosis].
In 21 patients with reflex syndromes of cervical osteochondrosis aged 24-63 years the authors studied short latent somatosensory evoked potentials (EP) in response to stimulation of the median nerve, the rate of impulse conduction along the efferent fibers of the ulnar and median nerves determined with the help of the P wave. The findings obtained by both methods showed a bilateral (on the side of pain and contralaterally) decrease in the rate of impulse conduction along the ulnar and median nerves. The study of the somatosensory systems by registration of EP on the side of pain revealed an increased amplitude and diminished latency of the P9 component which reflects manifestations of irritation of cervical cerebrospinal nodes.
