简要总结
Participants will be recruited and screened through ongoing studies in the sleep and anxiety disorders clinic. Participants with insomnia will be consented to complete several questionnaires, undergo a brief physical exam, provide a urinalysis, and undergo 5 nights of active or sham Low Field Magnetic Stimulation (LFMS) followed by an overnight sleep study. Each of the two treatment conditions (active versus sham) will be conducted on two consecutive nights. There will be no more than 7 days between the adaptation night and the first treatment condition and no more than 7 nights between each of the two-night treatment conditions . Thus, each participant who completes the full study will spend a total of 5 nights in the sleep laboratory and the time interval from the first adaptation night to completion of the study may range from 5-19 days for any particular individual.

结局指标
主要结局
Sleep Onset Latency (SOL) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
SOL is the time of transition from wake to sleep (non-REM S1) measured in minutes; a validated objective measure extracted directly from full-night polysomnography (PSG). SOL of 0-5min is associated with severe sleep deprivation; 5-10min is moderate sleep debt; 10-15min indicates mild sleep debt; 15-20min is little-to-no sleep debt; and \>20min is considered to be associated with no sleep debt.
Wake After Sleep Onset (WASO) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
Total time awake after initial sleep onset in minutes; validated objective measure directly extracted from polysomnography (PSG); we average measures from both consecutive nights under each of the two interventions (Sham or Active LFMS)
Total Sleep Time (TST) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
Total Sleep Time is the total time spent sleeping (non-wake stages S1-S5) in minutes; validated objective measure directly extracted from polysomnography (PSG).
Sleep Efficiency (SE) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
Sleep Efficiency (SE) is an objective measure of sleep quality derived from polysomnography (PSG); it is a unitless measure defined as the total sleep time (TST) divided by total time in bed (TiB); it can theoretically range from 0 (no sleep at all) to 1 (slept the entire time in bed). Values close to zero indicate very little time spent sleeping while values close to one indicate a large sleep utilization while in bed.
Ease of Sleep (EOS) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
Ease of Sleep (EOS) is assessed after each night as a subjective measure; participants self-rate their ease to fall asleep on a visual analog scale 0-100mm where 0mm is associated with not easy at all (no sleep) and 100mm is associated with no problems to fall asleep. EOS is a proxy measure for a participants sleepiness.
MUSC Sleep Quality Score (SQS) After Sham vs. Active LFMS (Each Averages of Two Consecutive Nights); and Difference From Baseline (Adaptation Night)
时间窗: Each night (5 nights total): Baseline (adaptation night #1), First Intervention (nights #2,#3), Second Intervention (nights #4,#5); Interventions randomized Sham or Active LFMS
MUSC Sleep Quality Score (SQS) is assessed after each night as a subjective measure; participants self-rate their perceived sleep quality on a 0-6 scale where 0 is associated with extremely poor sleep quality and 6 is associated with extremely good sleep quality.
