Arm | Intervention/treatment |
---|---|
Experimental: Sleep Onset Latency Crossover
Arm 1 is a crossover arm in which participants receive one block of active stimulation (experimental) and a second block in which the device is worn and actively recording, but not delivering phase-locked auditory stimulation (sham). The order of blocks is randomized for each participant.
|
Device: Elemind Neuromodulation (ENMod)
The ENMod is a headband that measures electroencephalogram (EEG) activity, computes the phase of neural oscillations in real-time, and delivers auditory pulses intended to interact with ongoing neural oscillations. |
Experimental: Wake After Sleep Onset
This arm tests active stimulation during sleep onset, as well as additional stimulation if participants wake up during the night. One of 4 possible conditions are randomized for each stimulation even (within subject and within nights): Stimulation locked to alpha peak phase, stimulation locked to alpha trough phase, white noise (active sham), and no sound (control).

- Change in Sleep Onset Latency (SOL) from Sham Block Compared to Stimulation Block [ Time Frame: At the completion of the study (14 days), including at least 4 days in each block. ]SOL will be determined using objective EEG-based metrics (e.x. time to first observed sleep spindle) derived from recommendations set forth by the American Academy of Sleep Medicine (AASM). SOL will be assessed for each study day during the sham block in which the device is worn but inactive and compared to SOL for the days in the stimulation block, in which the device is actively delivering auditory stimulation. Subjects will randomly be assigned in regards to the order of sham and stimulation blocks.
- Change in Sleep Efficiency During Sham Block Compared to Stimulation Block [ Time Frame: At the completion of the study (14 days), including at least 4 days in each block. ]Sleep efficiency, defined as the percentage of time spent asleep out of the total time spent in bed will assessed for each study day during the sham block in which the device is worn but inactive and compared to the sleep efficiency for each day in the stimulation block, in which the device is actively delivering auditory stimulation. Subjects will randomly be assigned in regards to the order of sham and stimulation blocks.
- Sleep Onset Latency After Wake After Sleep Onset Events (WASO) During Sham Stimulation Sessions Compared to Active Stimulation Sessions [ Time Frame: At the completion of the study (7-14 days). ]Sleep onset latency will be measured after middle-of-night wake up events using EEG-based metrics according to guidelines set forth by the American Academy of Sleep Medicine (AASM). Stimulation condition (sham or active) will be randomized for each WASO event (including events within a single night as well as across all nights). At the completion of the study, SOL will be compared for WASO events in which sham stimulation was delivered compared to WASO events in which active stimulation was delivered.
- Change in Subjective Sleep Onset Latency (SOL) from Sham Block Compared to Stimulation Block [ Time Frame: At the completion of the study (14 days). ]Subject-reported time to fall asleep will be assessed using the results from a questionnaire that includes the first 9 questions from the Consensus Sleep Diary (Carney et al., 2012). This survey asks the participant to report bed time, wake time, the amount of time it took to fall asleep, the number of awakenings during the night and the total duration of such awakenings. The questionnaire also asks the subject to rate quality of sleep on a 5-point scale from very poor to very good. The reported time to fall asleep on days during the sham block will be compared to the same metric reported on days during the stimulation block.
- Change in Subjective Daytime Sleepiness (Karolinska Sleepiness Scale) from Sham Block Compared to Stimulation Block [ Time Frame: At the completion of the study (14 days). ]Subject-reported feelings of sleepiness and alertness during the day will be assessed using the Karolinska Sleepiness Scale (KSS) questionnaire. This is a single question scale on which sleepiness is assessed using a score from 1-9, with 1 representing a level of high alertness, and 9 representing very sleepy. The reported KSS score during the sham block will be compared to the same metric reported on days during the stimulation block.
