About this trial

This is an interventional basic science trial for Sleep Disorders focused on measuring Sleep Apnea, Insomnia, sleep disorders, sleep environment, core body temperature

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Adults Age 18-65 who are scheduled for a diagnostic sleep study at the Stanford Sleep Clinic for sleep disorders (including but not limited to, insomnia, Sleep Apnea or other sleep disorder symptoms).

Exclusion Criteria:

  • Individuals with a history of having difficulty swallowing food or large capsules. We will not be able to enroll individuals with any known or suspected obstructive disease of the gastrointestinal tract including, but not limited to esophageal stricture, diverticulosis and inflammatory bowel disease (IBD), peptic ulcer disease, Crohn's disease, ulcerative colitis, previous gastrointestinal surgery.
  • Individuals who are pregnant.
  • Individuals who are unable to provide informed consent (i.e. decisionally impaired).

Outcomes

Primary Outcome Measures

Total Sleep Time
Sleep Efficiency Assessed by Polysomnography (PSG)
Sleep efficiency is total sleep time divided by time in bed. All data were collected through the PSG data that were retrieved from the patients' medical records after completion of the recordings and analysis by the sleep technologists.
Sleep Latency Assessed by PSG
The amount of time from lights off to falling asleep.
Wake After Sleep Onset (WASO) Assessed by PSG
Total amount of minutes awake after the first sleep epoch.
Percentage of Time in Bed During Each Sleep Stage
Position Changes Assessed by PSG
Number of times participant changed position during the sleep recording.
Apnea Hypopnea Index Assessed by PSG
The number of apneas or hypopneas recorded during the study per hour of sleep.
Heart Rate
Periodic Leg Movements (PLM) During Sleep
Number of times participant had periodic leg movements during the sleep recording
Mean EEG Delta Spectral Power Per Second Over 90 Mins From Lights Off Between 0-360 Minutes After Lights Off
EEG data collected from the electrode in position C2

Secondary Outcome Measures

Core Body Temperature
Difference in core body temperature changes of the high and low rebound mattress toppers at sleep onset and during sleep. The core body temperature will be monitored every minute throughout the night.
Visual Analog Scale of Sleep
visual analog scale of sleep was used for evaluation of subjective sleep quality. Scale ranged from 0 cm (very bad) to 10 cm (very good).
Visual Analog Scale of Performance
visual analog scale of performance was used for evaluation of subjective performance quality. Scale ranged from 0 cm (very bad) to 10 cm (very good).
Visual Analog Scale of Mood
visual analog scale of mood was used for evaluation of subjective mood. Scale ranged from 0 cm (very bad) to 10 cm (very good).
Alliance Sleep Questionnaire (ASQ)
self-reported information related to sleep

5. Study Description

Brief Summary
The purpose of the study is to evaluate effects of high rebound mattress toppers (i.e., airweave®) on sleep and sleep-related symptoms. The study will compare effects of use of high rebound mattress toppers versus use of low rebound mattress toppers on sleep and sleep related symptoms and core body temperature during diagnostic sleep studies.
