I went, including the jaw movement with a Six-Degree-of-FreedomJaw Tracking System for Sleep Study, the measurement of biological signals such as EMG,EEG.(1)To target the three subjects, consider what jaw movement is what has occurred in the case of body motion and arousal reaction during sleep, awakening occurs 13.3 times average during sleep, 77.5% is during sleep which I was accompanied by jaw movement of bruxism like.(2)To target the 12 subjects, we examined the relationship between masseter muscle activity and jaw clenching in the time of bruxism during sleep. To bruxism events during sleep time, and clenching interval interval jaw movement is still 2sec or more, in the chin in the 86 times (76.1%), 1mm or more away is the thing with thejaw in the 0.5mm or less if intercuspal position 17 times (15.0%) ones were observed.
