Abstract

To clarify the accuracy of a portable electromyogram (EMG) device, simultaneous recordings of the EMG during sleep detected via polysomnography (PSG) with sampling rate of 1000 Hz and the portable EMG device with 16 Hz were determined in three male subjects (22.7 ± 0.6 years old) having sleep bruxism referral.
Under the event of EMG recorded from the PSG was set as a gold standard, the detected rate from the portable EMG device for a tonic, a phasic and a mixed type were 94.1, 80.0 and 83.3 %, respectively. From the results above, it is fair to say that 16 Hz sampling rate showed good enough for the tonic event detection, however it would be better for the phasic and mixed events to increase higher rate of data sampling.
