Surface electromyography (sEMG) measures myoelectrical signals recorded from sensors placed on the skin surface. The non-invasive nature of sEMG makes it a potentially useful technology for studying diseases of muscle and nerve. Reviews published by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM) and the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology (AAN), covering 1964-1994 and 1952-1998, respectively, concluded that sEMG adds no clinical utility over conventional needle EMG (nEMG) for the diagnosis of neuromuscular disease. The AANEM sEMG task force reevaluated the diagnostic utility and added value of this technology for the study of neuromuscular disease based on a contemporary review of relevant literature published between January 1994 and February 2006. The present review concludes that sEMG may be useful to detect the presence of neuromuscular disease (level C rating, class III data), but there are insufficient data to support its utility for distinguishing between neuropathic and myopathic conditions or for the diagnosis of specific neuromuscular diseases. sEMG may be useful for additional study of fatigue associated with post-poliomyelitis syndrome and electromechanical function in myotonic dystrophy (level C rating, class III data).
表面肌电图（sEMG）可测量从置于皮肤表面的传感器记录到的肌电信号。sEMG的非侵入性使其成为研究肌肉和神经疾病的一种潜在有用技术。美国神经肌肉与电诊断医学协会（AANEM）以及美国神经病学学会治疗与技术评估小组委员会（AAN）分别发表的涵盖1964年至1994年以及1952年至1998年的综述得出结论，在诊断神经肌肉疾病方面，sEMG相较于传统针电极肌电图（nEMG）并无临床优势。AANEM的sEMG特别工作组基于对1994年1月至2006年2月期间发表的相关文献的当代综述，重新评估了该技术在研究神经肌肉疾病方面的诊断效用和附加价值。本综述得出结论，sEMG可能有助于检测神经肌肉疾病的存在（C级评级，III类数据），但尚无足够数据支持其在区分神经病变和肌病情况或诊断特定神经肌肉疾病方面的效用。sEMG可能有助于对与小儿麻痹后遗症相关的疲劳以及强直性肌营养不良的机电功能进行进一步研究（C级评级，III类数据）。
