[Attempt at objective evaluation of pain and analgesia during stimulation of the posterior columns in patients with spinal cord lesions].
In a group a patients with a pain syndrome in spinal cord injury electric stimulation of n. medianus causes the appearance of a component of a somatosensory induced potential (IP) which is a high-amplitude superficial-positive oscillation with a latent peak period of 200-280 mc. A similar oscillation is revealed in a group of healthy individuals in response to nociceptive stimulation of the skin on the forearm. The amplitude of this potential reduced markedly in effective antipain stimulation through electrodes implanted into the posterior columns of the spinal cord. In the absence of an antipain effect the oscillation described persisted at the time of the patient's discharge from the clinic. The existence of a connection between the described potential (P240) with the pain syndrome and the perception of pain stimulation is suggested. On the basis of the data obtained the possibility of objectifying the intensity of the pain sensations by somatosensory IP recording is contemplated.
