An interventional study of Smart pillow in Snoring and Obstructive Sleep Apnea, sponsored by Indiana University. Recruiting at 1 site in United States. Open to participants aged 50 Years and older. Per ClinicalTrials.gov, last updated 2026-08-21.
Sponsored by Indiana University · Not applicable, Interventional, and Supportive care
The purpose of this study is to examine the impact of smart pillows on the sleep quality of individuals who experience a snoring issue and/or obstructive sleep apnea (OSA), as well as their sleep partners. Furthermore, this study will explore whether enhancements in sleep quality positively influence depressive symptoms, physical activity, heart rate, blood oxygen levels, and cognitive functions.
The study's timeline consists of 3 phases:
During the Pre-Evaluation phase, participants and their sleep partners will complete questionnaires related to sleep quality and depression. Participants and sleep partners will each be asked to wear an actigraphy watch continuously for the 7 days immediately prior to the intervention phase (Study Day -7 through Study Day -1). The actigraphy watch will collect data on various objective sleep quality measures and on other health measures. Additionally, participants and sleep partners will also complete a daily sleep log and a daily sleep questionnaire during this pre-evaluation phase. The participant (individual with snoring or OSA) will also set up the pillow's control box next to the bed to collect baseline data on snoring patterns.
During the Intervention phase, participants with snoring issues or OSA will be asked to use the study pillow for 14 days (Study Day 1 through Study Day 14). The pillow features a center that detects the head position and six airbags that can add and remove air individually. If the pillow detects snoring, it will adjust the position of the participant's head by adjusting the amount of air in each airbag. This repositioning is gentle, produces minimal noise, and will not disrupt the participant's sleep or wake them. Participants will be provided with instructions on how to use the pillow. Participants may continue current snoring or OSA treatments during this time. During the intervention phase, sleep partners will be asked to continue to share a sleeping space with the participant, as they are used to doing.
The post-evaluation phase begins half-way through the intervention phase and continues through discontinuation of the study pillow (Study Day 8 through Study Day 14). During the post-evaluation phase, participants and sleep partners will repeat the assessments from the Pre-Evaluation phase, including the daily wear of the actigraphy watch and the daily sleep log and questionnaires.

Change in Participant Subjective Sleep Quality (PSQI)
Subjective sleep quality will be measured by the Pittsburgh Sleep Quality Index (PSQI). The PSQI score ranges from 0-21. A higher score indicates worse sleep quality. The PSQI will be administered prior to use of the study pillow and again after discontinuing use of the study pillow.
Time frame: Baseline and Day 14
Change in Participant Subjective Sleep Quality (novel sleep quality questionnaire)
Subjective sleep quality will also be measured by a novel questionnaire created for this project. Questionnaire score ranges from 3-15. A higher score indicates better sleep quality. Participants will be asked to complete this questionnaire 14 times during their participation: once daily for the 7 days prior to initiating use of the study pillow (Day -7 through Day -1) and once daily for the last 7 days of study pillow use (Day 8 - Day 14).
Time frame: Day -7 through Day -1 and Day 8 through Day 14
Change in Participant total sleep time
As part of measuring objective sleep quality, total sleep time will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).
Time frame: Day -7 through Day -1 and Day 8 through Day 14
Change in Participant sleep periods
As part of measuring objective sleep quality, sleep periods (light and deep sleep) will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).
Time frame: Day -7 through Day -1 and Day 8 through Day 14
Change in Participant REM sleep time
As part of measuring objective sleep quality, REM and non-REM sleep time will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).
Time frame: Day -7 through Day -1 and Day 8 through Day 14
Change in Participant Snoring time
The study pillow (Nitetronic Z6 smart pillow) will collect data on total time spent snoring and the intensity of the snoring. Participants will be asked to use the study pillow for 14 consecutive nights during their participation (Day 1 through Day 14).
Time frame: Days 1 - 14 (during use of the study pillow)
Change in Participant Depressive symptoms
Depressive symptoms will be measured using the Center for Epidemiologic Studies Depression Scale, 8-item (CES-D-8). The CES-D-8 score ranges from 0 to 8. A higher score indicates more severe depressive symptoms.. The CES-D-8 will be administered prior to use of the study pillow and again after discontinuing use of the study pillow.
Time frame: Baseline and Day 14
Change in Participant blood oxygen level
Blood oxygen level will be measured using the Fitbit Inspire 3 (an actigraphy watch).

Time frame: Day -7 through Day -1 and Day 8 through Day 14
Change in Participant's subjective cognitive function
Subjective cognitive function will be measured by a two-question questionnaire: 1) 'How would you rate your memory at the present time? Would you say it is excellent, very good, good, fair, or poor?' and 2) 'Compared to the previous month, would you say your memory is better now, about the same, or worse than it was then?' The two-question questionnaire will be administered prior to the use of the study pillow and again after discontinuing the use of the study pillow.
Time frame: Baseline and Day 14
Change in Participant's objective cognitive function
Objective cognitive function will measured by the Montreal Cognitive Assessment (MoCA). The MoCA score ranges from 0-30. A higher score indicates better cognitive function. The MoCA will be administered prior to the use of the study pillow and again after discontinuing the use of the study pillow.
Time frame: Baseline and Day 14
Change in Partner's Subjective Sleep Quality (PSQI)
Subjective sleep quality will be measured by the Pittsburgh Sleep Quality Index (PSQI). The PSQI score ranges from 0-21. A higher score indicates worse sleep quality.
