Yanez-Regonesi: Diagnostic Accuracy of a Portable Device (Bruxoff®) to Measure Sleep Bruxism

Diagnosis of sleep bruxism supposes a challenge to clinicians given the fact that the definite diagnosis relies in laboratory polysomnography (PSG). The use of the latter is limited due to poor access and high costs. Bruxoff ® is a portable device combining electromyography and heart rate measurement. The device was already proven reliable compared to home sleep study. The aim of this study is to investigate the reliability and validity of the Bruxoff® device for the diagnosis of SB compared to the PSG (gold standard). Subjects will be recruited from patients who will receive a full PSG study at the Good Samaritan Hospital in the University of Kentucky. We will evaluate for self-reported SB with the questionnaire of the American Academy of Sleep Medicine (AASM). Patient will have a polysomnographic study performed along with the recording from the Bruxoff® device. Scoring of rhythmic masticatory muscle activity (RMMA) will be performed and Bland-Altman plot analysis will be utilized to quantify the level of agreement between devices.
