The primary objective of this study is to determine the technical failure and inconclusive test rates when using the Brizzy device for mandibular movement tracking.
Study Type
OBSERVATIONAL
Enrollment
4,231
Patients wore the Brizzy device while sleeping. Mandibular movements (A mid-sagittal mandibular movement magnetic sensor measured the distance in mm between two parallel, coupled, resonant circuits placed on the forehead and chin.) were tracked during sleep.
The exploitable data rate
