A group of 20 consecutive patients with amyotrophic lateral sclerosis (ALS) were evaluated using electromyography (EMG) and ultrasonography (US) of the tongue. Their records were reviewed retrospectively for the rates at which abnormalities were detected by these two modalities as well as their clinical features. Visual inspection detected abnormalities in 9 of 20 patients, EMG in 12, and US in 6. However, EMG detected active denervation earlier than did US in 7 of the 12 EMG-diagnosed patients, and US detected fasciculation earlier than did EMG in 1 of the 6 US-diagnosed patients. Thus, we cannot replace EMG completely with US. Indeed, we currently use both methods complementarily at our hospital.
对一组连续的20例肌萎缩侧索硬化症（ALS）患者进行了舌肌肌电图（EMG）和超声检查（US）评估。回顾性分析他们的记录，以了解这两种检查方式检测到异常的比率及其临床特征。通过肉眼检查在20例患者中的9例发现异常，EMG检查发现12例异常，US检查发现6例异常。然而，在12例经EMG诊断的患者中，有7例EMG比US更早检测到主动失神经，在6例经US诊断的患者中，有1例US比EMG更早检测到肌束震颤。因此，我们不能完全用US替代EMG。实际上，我们医院目前同时使用这两种方法作为补充。
