摘　　要：对５０名ＴＭＪＤＳ患者进行了姿势位和牙尖交错位最大紧咬时双侧颞肌前束、颞肌后束、嚼肌及二腹肌的肌电检查，并以５０名同龄健康人作为对照观察。结果表明ＴＭＪＤＳ患者关节区疼痛侧颞肌后束姿势电位明显高于对照组．其余各肌与对照组无显著差异；而牙尖交错位最大紧咬时ＴＭＪＤＳ患者的颞肌前束、嚼肌肌电平均值显著低于对照组，其余各肌与对照组无明显差异。提示电生理检查可望成为对ＴＭＩＤＳ诊断及判断疗效的一种指标。Abstract The bilateral anterior and posterior temporalis,masseter and anterior digastric were given electromyograph analyses for 50 cases of TMJDS in the postural position and the intercuspal position when clinching most forcelly. 50 health people were control. The results showed the levels of EMG of posterior temporalis TMJDS patients in painful sides were much higher than those of control. The EMG levels of the rest muscles were obviously different from control. The anterior temporalis and masseter showed much lower average EMG values when TMJDS patients clinched most forcelly in intercuspal position. The EMG levels of the rest muscles had no significant difference with control.The results suggested the electrobiological examination can be used to evaluate effect treating TMJDS.
