摘　　要：目的利用口外表面电极定量测量下颌肌电活性,验证是否能基本反应上气道扩张肌(主要指颏舌肌)活性的变化趋势,即有效性的研究;验证不同时间重复测量两次的结果是否一致,即稳定性的研究。方法利用口外表面电极测量下颌肌电,且和整夜多道睡眠监测(polysomnography,PSG)同步,对10例阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)患者整夜睡眠阶段的下颌肌电的活性变化给予分析;比较清醒期、非快眼动(non rapid eye movement,NREM)期睡眠和快眼动(rapid eye movement,REM)期睡眠不同阶段的肌电变化;分析呼吸暂停事件期间肌电活性的变化;将下颌肌电活性的变化趋势和口内表面电极测量的颏舌肌活性的变化趋势做一比较,验证其有效性;1周后重新行PSG和下颌肌电检查,比较两次的结果是否一致,验证其稳定性。结果10例OSAHS患者不同睡眠阶段下颌肌电的变化及呼吸暂停事件期间下颌肌电的变化是和口内表面电极反应的颏舌肌肌电的变化趋势一致;口外表面电极1周前、后两次测量的下颌肌电活性变化规律基本一致。结论利用口外表面电极测量下颌肌电,其变化规律能基本反应上气道扩张肌(主要指颏舌肌)活性的变化规律,是有效的,且有很好的稳定性。OBJECTIVE To evaluate the validity 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.
