Abstract
Background and 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.
Conclusion
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.
期刊介绍：
Respiratory Physiology & Neurobiology (RESPNB) publishes original articles and invited reviews concerning physiology and pathophysiology of respiration in its broadest sense.
Although a special focus is on topics in neurobiology, high quality papers in respiratory molecular and cellular biology are also welcome, as are high-quality papers in traditional areas, such as:
-Mechanics of breathing-
Gas exchange and acid-base balance-
Respiration at rest and exercise-
Respiration in unusual conditions, like high or low pressure or changes of temperature, low ambient oxygen-
Embryonic and adult respiration-
Comparative respiratory physiology.
Papers on clinical aspects, original methods, as well as theoretical papers are also considered as long as they foster the understanding of respiratory physiology and pathophysiology.
