About this study
Official title: Sleep Position Pattern Recording - A Validation Study
The main goal of this study is to validate the accuracy of the body position detection by non-invasive wearable monitors (Skiin garments, Myant Medical Corp) during sleep in pregnant participants. This is a first step towards examining the association between maternal sleep position and fetal growth.
Read the detailed description
Individuals who are eligible to the study and provided consent to participate will be asked to:
- Wear the Skiin Garment system for the duration of their time in the hospital (minimum 1 nights until they are discharged from hospital).
- Complete a study completion questionnaire about their experience with the device and the study.
The Skiin Garment system is composed by biosensing garments presented in different form factors (bra, chest band, or underwear). It captures physiological metrics and relay information from a pod to local hub with Bluetooth.
The true body position will be obtained using visual observations and cameras.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Skiin Garment systemDevice
Individuals will be asked to wear a Skiin Garment system for the duration of their hospitalization (minimum one day).The system will collect accelerometer, ECG, temperature, heart rate, steps and sleep metrics data if enable. Then, they will be asked to answer a questionnaire about their experiences with the device and the study.
| Study group | Role | What they receive |
|---|---|---|
| Sleep position detection | Accuracy of Skiin Garment system for detecting sleep position of pregnant womem. Receives: Device: Skiin Garment system |
What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy of Skiin Garment system for detecting sleep position of pregnant women
Sleep position will be identified through the Skiin Garment system via accelerometry, and compared to visual confirmation of sleep position.
Measured: Recorded during the night, during 6 to 8 hours.
Secondary outcomes (3)
Questionnaire on wearable device invasiveness and satisfaction
Pregnant women will be asked to answer a questionnaire at the end of their participation in the study. It contains questions related to patients' experience wearing the Skiin Garment system, including invasiveness and satisfaction.
This is an ad-hoc questionnaire titled "SPV_Satisfaction_Questionnaire_v1_2023-04-03" containing 20 questions: 14 questions use a Likert scale design, 3 questions are single choice answer, and 3 questions are open-ended questions. Results are not reported as a total score on a scale but descriptive statistics will be used individually per question.
Measured: One time point, on the morning after one night wearing the Skiin Garment system
Participant recruitment rate
Recruitment rate will be calculated as the number of participants who consent to participant divided by the number of participants who consent to be contacted.
Measured: From the beginning to the end of the recruitment, up to 1 year.
Participant retention rate
The retention rate will be calculated as the number of participants who remain in the study divided by the number of participants who initially consent to participate.
Measured: From the beginning to the end of participation, up to 1 year.
