To study the dynamics of bioelectric activity of the brain in patients with Insomnia after treatment by direct transcutaneous electroneurostimulation (TENS) of the right median nerve. Materials and methods: 19 patients with insomnia accompanied by increased slow EEG activity were studied. All patients showed signs of an increased theta activity index in the posterior and parietal regions. The theta activity index exceeded 25% and averaged 38%. All patients underwent direct transcutaneous electroneurostimulation of the right median nerve (TENS). 10 patients were managed by Low-frequency Highamplitude TENS (1 Hz, 200 mcs, 15 mA). 9 patients underwent a course of high-frequency low-amplitude TENS (100 Hz, 100 mcs, 5 mA). Results: Theta activity index decreased in patients who underwent a course of low-frequency high-amplitude TENS by an average of 39%. In patients after high-frequency low-amplitude TENS, indicators of slow activity did not significantly change. A decrease in the severity of paroxysms of slow activity was also noted against the background of low-frequency and high-amplitude TENS. Conclusion: The low-frequency high-amplitude TENS, in contrast to the high-frequency low-amplitude TENS, can improve the EEG indices in patients with insomnia. This improvement is manifested by a significant decrease in the index of theta activity in the posterior and parietal regions and a decrease in the severity of paroxysmal activity of the theta rhythm.
