Clinical Trial 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.

Outcome

Type Measure Description Time frame Safety issue
Primary Total Sleep Time Overnight study visit (up to approximately 10hrs)
Primary 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. Overnight study visit (up to approximately 10hrs)
Primary Sleep Latency Assessed by PSG The amount of time from lights off to falling asleep. Overnight study visit (up to approximately 10hrs)
Primary Wake After Sleep Onset (WASO) Assessed by PSG Total amount of minutes awake after the first sleep epoch. Overnight study visit (up to approximately 10hrs)
Primary Percentage of Time in Bed During Each Sleep Stage Overnight study visit (up to approximately 10hrs)
Primary Position Changes Assessed by PSG Number of times participant changed position during the sleep recording. Overnight study visit (up to approximately 10hrs)
Primary Apnea Hypopnea Index Assessed by PSG The number of apneas or hypopneas recorded during the study per hour of sleep. Overnight study visit (up to approximately 10hrs)
Primary Heart Rate Overnight study visit (up to approximately 10hrs)
Primary Periodic Leg Movements (PLM) During Sleep Number of times participant had periodic leg movements during the sleep recording Overnight study visit (up to approximately 10hrs)
Primary 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 Overnight study visit (up to approximately 10hrs)
Secondary 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. Overnight study visit (up to approximately 10hrs)
Secondary 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). Overnight study visit (up to approximately 10hrs)
Secondary 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). Overnight study visit (up to approximately 10hrs)
Secondary 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). Overnight study visit (up to approximately 10hrs)
Secondary Alliance Sleep Questionnaire (ASQ) self-reported information related to sleep Overnight study visit (up to approximately 10hrs)
