| Outline of Final Research Achievements |
The purpose of this study was to investigate the usefulness of a bio-phenomena analyzing system using a small device with wireless LAN that records the bio-phenomena of a person during sleep. Five healthy subjects and 5 bruxists in their twenties were selected as subjects. Bio-phenomena of subjects during sleep were recorded using both a small device with wireless LAN and a wireless telemeter system. Analysis was performed on bio-phenomena obtained from a small device with wireless LAN and a wireless telemeter system. Sleep stages, heart rate, duration of masseter muscular activity during bruxism and its cumulative value were calculated and compared between the two devices. The values obtained were very similar for both devices, and no significant difference was found between the two devices. From these results it was concluded that the bio-phenomena recording system using a small device with wireless LAN has similar precision as the wireless telemeter system.
