Changes in parameters of laser-induced potentials after transcutaneous electroneurostimulation.

Changes in nerve conduction after 10-min electroneurostimulation of the posterior surface of the neck were studied. Changes in the parameters of laser-induced potentials obtained during stimulation of C7 dermatome on hands and posterior surface of the neck were found. Decrease in the amplitude and shortening of the component latency were shown. Method of laser-induced potentials was concluded to provide unbiased estimation of the level and peculiarities of analgesic effects of physical factors.
