To verify the effect of a 5-day cranial electrotherapy stimulation (CES) intervention on sleep quality in professional athletes.
25 professional athletes with poor sleep quality participated in the study. Athletes belonging to the CES group (12 athletes) received a 5-day CES intervention, and those in the control group did not receive any intervention. Objectively and subjected assessed sleep quality was measured 1 week before and after the intervention using an Actigraphy activity recorder, Pittsburgh sleep quality index (PSQI), and Insomnia Severity Index (ISI).
Objectively measured sleep efficiency increased after CES intervention (P = .013), while the difference between the pretest and posttest of the control group was not significant. For total sleep time (TST), the main effects and interaction were not significant. However, the analysis on wake after sleep onset showed wake after sleep onset decreased after CES intervention (P = .015). No significant interaction was found in subjectively assessed sleep quality but only revealed an improvement in both groups.
The CES intervention of 30 minutes per day for 5 consecutive days enhanced objective sleep quality in athletes with sleep quality problems. The intervention increased sleep efficiency by lowering awake time after falling asleep.
验证 5 天经颅直流电刺激（CES）干预对职业运动员睡眠质量的影响。
25 名睡眠质量差的职业运动员参加了这项研究。CES 组（12 名运动员）接受了 5 天的 CES 干预，对照组则没有接受任何干预。干预前后 1 周使用活动记录仪、匹兹堡睡眠质量指数（PSQI）和失眠严重程度指数（ISI）客观和主观评估睡眠质量。
CES 干预后客观测量的睡眠效率提高（P =.013），而对照组的前后测试差异不显著。对于总睡眠时间（TST），主效应和交互作用不显著。然而，对睡眠后觉醒的分析显示，CES 干预后睡眠后觉醒减少（P =.015）。主观评估的睡眠质量没有显著的交互作用，但仅显示出两组都有改善。
每天 30 分钟，连续 5 天的 CES 干预增强了有睡眠质量问题的运动员的客观睡眠质量。该干预通过降低入睡后醒来时间来提高睡眠效率。
