我们通过夜间睡眠中断计划诱导正常受试者孤立性睡眠瘫痪（ISP）。在四个实验夜晚，16名受试者在第一或第三个睡眠周期的快速眼动（REM）睡眠结束后，在40分钟的非快速眼动（NREM）睡眠结束后被强迫唤醒，从而中断了60分钟的睡眠。该计划在中断后产生睡眠性快速眼动期（SOREMP），其发生率高达71.9%。我们成功地在睡眠中断中诱发了6次ISP发作（9.4%）。除1例外，所有ISP均发生于SOREMP，表明ISP与SOREMP密切相关。我们记录了ISP体验的口头报告，并记录了ISP过程中的多导睡眠图（PSG）。所有患有ISP的受试者都无法移动，同时也意识到自己躺在实验室里。除一人外，所有人都报告了听觉/视觉幻觉和不愉快的情绪。ISP期间的PSG记录表现为REM/W阶段解离状态，即丰富的α脑电图和强直肌电图显示的肌肉张力持续存在。从PSG记录来看，ISP不同于其他解离状态，如清醒梦、夜间惊恐发作和REM睡眠行为障碍。我们比较了一些睡眠变量之间的ISP和非ISP的夜晚。我们还讨论了嗜睡症中ISP与睡眠瘫痪的异同。
We elicited isolated sleep paralysis (ISP) from normal subjects by a nocturnal sleep interruption schedule. On four experimental nights, 16 subjects had their sleep interrupted for 60 minutes by forced awakening at the time when 40 minutes of nonrapid eye movement (NREM) sleep had elapsed from the termination of rapid eye movement (REM) sleep in the first or third sleep cycle. This schedule produced a sleep onset REM period (SOREMP) after the interruption at a high rate of 71.9%. We succeeded in eliciting six episodes of ISP in the sleep interruptions performed (9.4%). All episodes of ISP except one occurred from SOREMP, indicating a close correlation between ISP and SOREMP. We recorded verbal reports about ISP experiences and recorded the polysomnogram (PSG) during ISP. All of the subjects with ISP experienced inability to move and were simultaneously aware of lying in the laboratory. All but one reported auditory/visual hallucinations and unpleasant emotions. PSG recordings during ISP were characterized by a REM/W stage dissociated state, i.e. abundant alpha electroencephalographs and persistence of muscle atonia shown by the tonic electromyogram. Judging from the PSG recordings, ISP differs from other dissociated states such as lucid dreaming, nocturnal panic attacks and REM sleep behavior disorders. We compare some of the sleep variables between ISP and non-ISP nights. We also discuss the similarities and differences between ISP and sleep paralysis in narcolepsy.
