| Outline of Final Research Achievements |
Validation of the miniature sleep bruxism (SB) detection/analyzing device has not been evaluated. This study determined the validity of device compared to polysomnogram puls AV recording (PSG). Sensitivity, specificity and accuracy between device and PSG assessment were 1.00，0.88 and 0.93 in case cut-off criteria was set at score 1 to 2. These results suggested that this modified miniature detection/analyzing device would obtain the moderate to high validity in clinical use.
Association between SB and simultaneous comorbid motor activites is unclear. This study aimed to compare the the incidences of body motions between sleep arousal (SA) with SB (SAwSB) and SA without SB (SAw/oSB). Motor activities in SAwSB was significantly higher than that in SAw/oSB (t-test, p<0.01, 95.1+/-6.6 %, 69.2+/-19.5 %). Leg movement and swallowing were significantly frequent among the comorbidities. This suggested that SB can be cocomitantly activated with leg movemnet and swallowing in relation to SA.
