The objective of this study was to determine the diagnostic accuracy of ultrasound and electromyography for the detection of fasciculation in patients with amyotrophic lateral sclerosis and to compare detection rates between the two methods. By searching the Cochrane Library, MEDLINE, Excerpta Medica, and Latin-American and Caribbean Health Sciences Literature databases, we identified studies evaluating the diagnostic accuracy and fasciculation detection rates of ultrasound and electromyography. The Quality Assessment of Diagnostic Accuracy Studies, version 2, and RTI item bank tools were used for the evaluation of methodological quality. Ultrasound, for 10 s or 30 s, had a higher detection rate than did electromyography in all muscles evaluated. The overall detection rate (in patients) did not differ significantly between ultrasound for 10 s and ultrasound for 30 s. The accuracy of ultrasound for 10 s was 70% in muscles and 85% in patients. The accuracy of ultrasound for 30 s was 82% in patients. Ultrasound provided detection rates superior to those achieved with electromyography, independent of the examination time and muscles evaluated.
本研究的目的是确定超声和肌电图检测肌萎缩侧索硬化症患者肌束震颤的诊断准确性，并比较这两种方法的检测率。通过检索考克兰图书馆、MEDLINE、医学文摘数据库以及拉丁美洲和加勒比地区健康科学文献数据库，我们确定了评估超声和肌电图诊断准确性及肌束震颤检测率的研究。使用诊断准确性研究质量评估第2版和RTI项目库工具对方法学质量进行评估。在所有评估的肌肉中，超声检查10秒或30秒的检测率高于肌电图。在患者中，10秒超声检查和30秒超声检查的总体检测率无显著差异。10秒超声检查在肌肉中的准确性为70%，在患者中的准确性为85%。30秒超声检查在患者中的准确性为82%。超声检查的检测率优于肌电图，且与检查时间和评估的肌肉无关。
