Research Abstract

A portable sleep bruxism detection system with a wireless electromyograph, a wrist-watch type biological sensor and a noise level meter was developed. Validity of this system was tested by the reference video recording. Elevation of heart rate before the sleep bruxism event was confirmed and suppression of sleep bruxism with minimal electrical stimulation triggered by the elevation of heart rate was demonstrated.
