目的：探讨环甲肌肌电图用于评估肌萎缩侧索硬化症患者吞咽障碍的可行性。方法对25例伴或不伴吞咽异常的肌萎缩侧索硬化症患者行右侧环甲肌肌电图检查，并通过洼田饮水实验对吞咽功能进行评估，比较两种检查结果。结果25例中，11例环甲肌肌电图表现为典型的失神经支配，15例洼田饮水实验阳性，两种方法符合率为60％（15/25），其中阳性符合率为32％（8/25）。McNemar检验验证喉肌电图检查和洼田饮水试验的一致性，Kappa系数为0．219（P＝0．344）。结论环甲肌肌电图可用于评估肌萎缩侧索硬化症患者的吞咽功能，但存在一定的局限性。

Objective To investigate the clinical values of laryngeal electromyography (LEMG) for evaluating the amyotrophic lateral sclerosis(ALS) patients with swallowing disorder .Methods A total of 25 ALS patients with or without complaining of swallowing disorder were recruited for the study .Their right cricothyroid muscles were taken unilaterally with concentric needle electrodes by anterior cervical approach .Each patient was tested with Kub-ota drinking test too .Results Of all the 25 patients ,11 were found abnormal in the right cricothyroid muscle which presented with typical degeneration patterns ,15 cases were found abnormal by Kubota drinking test .The coinci-dence rate of the two methods was 60% ,the poisitive coincidence rate was 32% .The McNemar test showed there was some consistency between the drinking water test and LEMG (P=0 .344) ,and the Kappa coefficient was 0 .219 . Conclusion The cricothyroid muscle electromyography may also be a potential method to evaluate ALS patients since it seemed to offer an evidence of dysphagia related with abnormal sensory function of laryngeal mucosa .But there may be some limitations .
