Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 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)

Exclusion criteria

  • none

Treatment and study plan

Mandibular movement tracking

Device

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.

Other names: Brizzy (Nomics, Liege, Belgium)

Primary outcomes

  1. The exploitable data rate

    Time frame: Day 0 (retrospective cross-sectional study)

    The number of usable tests / the number of tests performed.

Secondary outcomes

  1. Respiratory disturbance index based on mandibular movements

    Time frame: Day 0 (retrospective cross-sectional study)

    Respiratory disturbance index based on mandibular movements (Brizzy, Nomics, Liege, Belgium)

  2. Minimal estimated total sleep time

    Time frame: Day 0 (retrospective cross-sectional study)

    Minimal estimated total sleep time

  3. ODI

    Time frame: Day 0 (retrospective cross-sectional study)

    The oxygen desaturation index (ODI) from oximetry.

  4. Type of prescriber (qualitative)

    Time frame: Day 0 (retrospective cross-sectional study)

    • other
  5. Identification of reasons why a given test was unusable

    Time frame: Day 0 (retrospective cross-sectional study)

  6. age
