Outline of Final Research Achievements

Sleep bruxism had some clinical signs which are transient jaw muscle fatigue or pain on the morning; and/or temporal headache. The object of this study was whether the cervical muscle activity was affected by jaw muscle during sleep.
There were hardly any association between the jaw muscle activity and the cervical for sleep questionnaire and polygraphic recording using young adult volunteers. In contrast, most of them felt to recover from their fatigue and good sleep. The stiff shoulder and neck were developed by daytime work (e.g. Service worker, Office worker), however, it might be possible to recover or sustain the fatigue and pain during sleep. Moreover, sleep bruxism and stiff and shoulder and neck did not affect sleep quality regarding to sleep variability.
