表面肌电信号(SEMG)在临床上仍很少用于肌电信号的检测和分析。在皮肤表面检测到的肌电信号包括来自感兴趣肌肉的更大比例的信息，而不是使用针电极获取的传统临床肌电。因此，表面肌电信号比目前使用的局部的、因此非常有选择性的针状肌电信号更具代表性。然而，表面肌电信号的可靠性和解释力都需要受到质疑。本文综述了利用肌电参数表征神经肌肉病理的研究进展。在介绍了表面肌电信号的原理和局限性之后，对在临床环境下获得的主要结果进行了概述并进行了讨论。高空间分辨率的表面肌电信号是目前针状肌电的选择性和经典表面肌电信号的代表性之间的最佳折衷，因此受到特别的关注。提出了几个观点，强调了表面肌电信号是一个不断发展的学科，应该在常规临床检查中占有一席之地。(C)2005年爱思唯尔集团。全。版权保留。
Surface electromyography (SEMG) is still rarely used in clinical settings for the detection and analysis of myoetectric signals. The etectromyographic signal detected on the skin surface includes information from a greater proportion of the muscle of interest than conventional clinical EMG, acquired using needle electrodes. SEMG is therefore more representative than the localised and thus very selective needle EMG signals currently used. However, both reliability and interpretation of surface EMG need to be questioned. This review looks at the studies concerned with the characterisation of neuromuscular pathologies using EMG parameters. After introducing principles and limitations of surface EMG, an overview of the main results obtained in clinical settings is presented and discussed. There is a particular focus on high spatial resolution surface EMG as it is currently the best compromise between the selectivity of needle EMG and the representative nature of classical SEMG. Several perspectives are proposed that underline the fact that surface EMG is an evolving discipline and should be worthy of a place in routine clinical examinations. (c) 2005 Elsevier SAS.
