Research on sleep regulation intervention method of transcranial alternating current stimulation in pilots
Journal Title: Journal of Air Force Medical University - Year 2023, Vol 44, Issue 5
Abstract
Objective In response to the current situation that pilots often need to break circadian rhythm for emergency missions, a sleep regulation intervention method of transcranial electrical nerve stimulation is studied to shorten the time to fall asleep and improve sleep quality, in order to achieve the purpose of improving combat effectiveness and flight safety in a short time. Methods A sleep intervention method based on low-frequency sinusoidal alternating current transcranial stimulation was proposed. Twenty subjects were recruited according to the design requirements, and each subject participated in three groups of sleep intervention experiments, namely, control group, pseudo-stimulation group and stimulation group. The stimulation group used transcranial nerve electrical stimulator to perform electrical stimulation intervention on subjects according to the stimulation scheme. The pseudo-stimulation group only stimulated the current when the stimulator was switched on and off, and did not stimulate the rest of the time. The electroencephalogram ( EEG), electrooculogram (EOG), electromyography (EMG) signals were synchronously monitored throughout the experiment, and relevant data were recorded. The collected EEG signals were analyzed by delta / theta power spectral density ratio, and the time to fall asleep of the subjects was determined by combining the EOG and EMG signals. Results The time to fall asleep in the control group, the pseudo-stimulation and the stimulation group was (17. 29 ± 7. 72) min, (11. 41 ± 4. 71) min and (5. 21 ± 3. 36) min, respectively. There was statistical difference in the time to fall asleep between the stimulation group and the control group (P < 0. 05), and there was no significant difference between the pseudo-stimulation group and the control group (P > 0. 05). Conclusion Stimulation group < pseudo-stimulation group < control group in the time to fall asleep proves that the transcranial nerve alternating current stimulation method can effectively shorten the time to fall asleep of the subjects.
