ENDOGENOUS ORGANISM RHYTHMS AS MODULATING FACTOR FOR STIMULATION PARAMETERS

The supposition about increased efficiency of sensory stimulation in t he case of feedback control of its parameters by patient's own endogen ous rhythm is experimentally tested, Transcutaneous electric nerve sti mulation with parameters being feedback controlled by patient's respir atory rhythm was used as a model in 12 male volunteers suffering from different ethiology pain. Significant activation of low frequency (8 d ivided by 10 Hz) alpha electroencephalogram components, deepening of b reath, the decrease or both muscle tension and galvanic skin response amplitudes, as well as pronounced pain relief effects together with in crease of functional stare and mood levels were the results of such tr anscutaneous electric nerve stimulation modification.
