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.
ABSTRACT
OBJECTIVE To investigate the effects of obstructive sleep apnea hypopnea syndrome on the quality of life of the patients. METHODS The quality of life was assessed with the Medical Outcomes Study SF-36 Health Survey in 145 patients with OSAHS and 17 snorers without OSAHS. Excessive Daytime Sleepiness was assessed with Epworth Sleepiness Scale. Pearson linear correlation and stepwise multiple regression analysis were used to study the association between each domain score of SF-36 and patients information,PSG parameters,EDS scores. RESULTS Three domains of SF-36 correlated negatively with Body Mass Index. Four domains correlated negatively with EDS. Three domains and total score correlated significantly with the lowest oxygen saturation. Two domains correlated negatively with the longest time of apnea. AHI and the lowest oxygen saturation have a mild side effect on the quality of life. BMI and EDS score have significantly side effect on the quality of the life. CONCLUSION Comparing to the mild OSAHS patients and snorers without OSAHS,the severe OSAHS patients have worse quality of life. EDS score and BMI have a significantly side effect on the severe OSAHS patients. OSAHS has a side effect on the quality of life of the patients.
