Research Abstract	The purpose of this study was to elucidate the chronic pain onset mechanism of craniocervical muscle by bruxism. Therefore, we measured stress, haemodynamics and muscle fatigue property, which are suspected of relation to the bruxism and chronic pain onset of craniocervical muscle, simultaneously with the bruxism. Although the results suggest that stress and muscle fatigue property is related to bruxism, we could not collect the adequate sample size for two years because it took time to establish the measurement method and collect the standard date of bruxism. However, it was thought that this study plays an important role of realization on the large-scale research using a large sample size.
