| Research Abstract |
The purpose of this study was to investigate the usefulness of a bio-phenomena recording system using a portable amplifier that records the bio-phenomena of a person during sleep. Ten healthy subjects and 10 bruxists in their twenties were selected as subjects. Bio-phenomena of subjects during sleep were recorded using both a wireless telemeter system and a portable system. Analysis was performed on bio-phenomena obtained from wireless telemeter system(NIHON KOHDEN Co., WEE-6112, WEB-5000) and portable system(S & ME Co., DL200). 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 portable amplifier has similar precision as the wireless telemeter system, and thus could be used clinically in analyzing sleep stages, heart rate, duration of masseter muscular activity during sleep bruxism and its cumulative value.
