Abstract：
METHODS: Little is known about self-induced cognitive trance (SICT) on respiratory function. The aims of this prospective, single-center, non-randomized, open-label study of healthy volunteers, were to characterize spirometry changes during SICT, confirm the safety of this technique, and investigate the potential clinical benefits of SICT.
RESULTS: Nine people participated. There were no significant difference in FEV1 FVC or FEF 25-75 before, during, and after SICT. There were significant improvements in grip strength during SICT (+2.2 kg/5.7 %, p<0.05) and in self-efficacy score related to physical activity at the end of the trance. One participant had a significant worsening of FEV1 during SICT in the context of a recent upper airway infection.
CONCLUSIONS: SICT does not significantly modify spirometry data in healthy volunteers and can improve self-efficacy related to physical activity. SICT should probably be performed with caution during upper airway infections.

摘要：
方法：关于呼吸功能的自我诱发认知恍惚（SICT）知之甚少。这个未来的目标，单中心,非随机化，健康志愿者的开放标签研究，是为了表征SICT期间的肺活量变化，确认这项技术的安全性，并研究SICT的潜在临床益处。
结果：有9人参加。FEV1FVC或FEF25-75前无显著差异,during,在割伤之后。SICT期间握力有显著改善（+2.2kg/5.7%，p<0.05），并且在恍惚结束时与身体活动有关的自我效能评分。在最近的上呼吸道感染的背景下，一名参与者在SICT期间FEV1显著恶化。
结论：SICT不会显著改变健康志愿者的肺活量测定数据，并且可以改善与体力活动相关的自我效能。上呼吸道感染期间应谨慎进行SICT。
