Abstract:
OBJECTIVE To evaluate the vali-dity and reliability of the outoral surface electrodes. METHODS The outoral surface electrodes were used to record the EMG activity of mandible muscles in 10 male OSAHS patients. The changes of EMG activity were observed among different sleep stages,during the apnea events,and which were compared with that recorded with intraoral surface electrodes from other researchers in our sleep center. The EMG activity was recorded again 7 days later with outoral surface electrodes in those 10 patients. RESULTS The characteristics of mandible muscular electrical activity in OSAHS patients by outoral surface electrodes were consistent to the characteristics of genioglossal electrical activity by intraoral surface electrodes. EMG activity was consistent between the 2 times recording results. CONCLUSION It is valid and reliable in measuring the EMG activity of mandible muscles by using outoral surface electrodes.
