Laryngeal electromyography (LEMG) evaluates the integrity of the neuromuscular system in the larynx by recording action potentials generated in the laryngeal muscles during voluntary and involuntary contraction. LEMG is particularly useful for helping to differentiate between disorders involving upper motor neurons, lower motor neurons, peripheral nerves, the neuromuscular junction, muscle fibers, and the laryngeal cartilages and joints. LEMG should be considered to be an extension of the physical examination, not an isolated laboratory procedure. A careful history and laryngeal evaluation determine the indication for LEMG and which muscles or muscle groups, in particular, are to be studied. Abnormalities detected by LEMG are always interpreted within the context of the clinical picture.
喉肌电图（LEMG）通过记录在自主和非自主收缩期间喉肌产生的动作电位来评估喉神经肌肉系统的完整性。LEMG对于区分涉及上运动神经元、下运动神经元、周围神经、神经肌肉接头、肌纤维以及喉软骨和关节的疾病特别有用。应将LEMG视为体格检查的延伸，而非一项孤立的实验室检查。详细的病史和喉部评估决定了LEMG的适应证以及具体要研究哪些肌肉或肌肉群。LEMG检测到的异常总是在临床情况的背景下进行解读。
