目的 研究表明5 Hz微电流刺激可能具有催眠作用。然而目前缺乏此研究结果对睡眠模式影响作用的证据，该干预措施的有效性尚未得到充分验证。为弥补这一研究空白，本研究采用交叉实验设计并招募失眠与非失眠受试者进行进一步验证。方法 招募10名失眠受试者和10名健康受试者。采用交叉设计，在顶颞叶区域施加真刺激和假刺激。研究评估了该刺激对多个指标的影响，包括主观睡眠质量、睡眠效率、睡眠结构、抑郁和焦虑症状以及精神运动警觉任务表现。结果 在睡前接受5 Hz微电流刺激的受试者，相较于接受虚拟刺激的受试者，其睡眠效率、睡眠质量和心理状态均显著改善。此外，接受真刺激的受试者表现出更高的睡眠效率和快速眼动睡眠的延迟。这些结果表明，睡前5 Hz微电流刺激能够提高睡眠效率的客观和主观指标。结论 睡前5 Hz微电流刺激不仅提高了受试者的睡眠效率，还改善了其对睡眠质量的主观感受。
Abstract：Objective Previous studies have suggested that bilateral 5-Hz microcurrent stimulation has a hypnotic effect, but the lack of evidence on how the stimulation affects subjects' sleep limits the validation of this intervention. To address this gap, a crossover experimental design was employed, recruiting both insomnia and non-insomnia subjects. Methods 10 participants with insomnia and 10 healthy participants were selected to attend our study. In this crossover study, true(5 Hz) vs. sham stimulation was applied over the parietal temporal lobes. Impact of stimulation on subjective sleep experience, sleep efficiency, sleep structure and psychomotor vigilance task(PVT) was assessed. Results Subjects who received the true 5-Hz stimulation before bedtime had significantly enhanced sleep efficiency, sleep quality, and mental state compared to the night of sham stimulation. Additionally, subjects who received true stimulation exhibited higher sleep efficiency and a later appearance of dream sleep. These findings suggest that 5-Hz microcurrent stimulation before bedtime can enhance both objective and subjective sleep efficiency. Conclusion 5 Hz microcurrent stimulation before bedtime improved sleep efficiency of subjects and also enhanced their subjective perception of sleep.
