PURPOSE To investigate the hypothesis that sleep bruxism (SB) events could be predicted by an increase in heart rate. MATERIALS AND METHODS Fourteen sleep bruxers were recruited. Each participant recorded his or her own electromyography (EMG) and electrocardiography (ECG) at home for 2 consecutive nights using a portable telemetry system. Ten heartbeats before (B10 to B1) and three heartbeats after (A1 to A3) the onset of SB events were analyzed, and the threshold for the prediction of an SB… CONTINUE READING
