Outline of Final Research Achievements

[Purpose]: The objective of this study is to clarify how sleep and physical activities affect chronic myalgia in TMD patients. [Materials and Methods]: Female TMD patients (n=7) and female non-TMD patients (n=9) were recruited. Sleep condition and physical activities were recorded with Actigraph for 14 consecutive days. [Results]: The higher the previous day’s physical activity (OR=0.992, p=.000) and the quality of last-night sleep (OR=0.997, p=.038), the lower the jaw pain in the first period became. The higher the previous day’s physical activity (OR=0.997, p=.033) and the quality of last-night sleep (OR=0.993, p=.001), the lower the jaw pain in the second period became. The higher the jaw pain of the previous day, the lower the sleep quality became (Odds ratio=.993, p=.049). [Conclusions]: These results suggest that sleep quality and physical activities affect chronic myalgia and that the chronic myalgia and sleep status could form the vicious cycle.
