Study Arms (1)

The study population

The study population is comprised of all patients included in the Brizzy register, Belgium.

Device: Mandibular movement tracking

Interventions

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.

Also known as: Brizzy (Nomics, Liege, Belgium)

You may qualify if:

  • Patient included in the Brizzy register
  • Mandibular movement test prescribed by practitioner
  • Patient performed a mandibular movement test (ambulatory setting) using a magnetic sensor (Brizzy, Nomics, Liege, Belgium)

You may not qualify if:

  • none
