Thirty-one EMG studies of the pharyngeal musculature using three types of electrodes were performed. Electrode characteristics are compared according to criteria developed specifically for the pharynx; techniques for electrode positioning are described in detail; and technical difficulties encountered in performing these studies are discussed. Needle electrodes were best for analyzing individual potentials. For analyzing the timing of myoelectric activity, we preferred the hooked wire electrode (for palatopharyngeus or cricopharyngeus) or bipolar suction electrode (for pharyngeal constrictors). Pharyngeal electromyography is technically feasible and has a role in studying normal and pathologic processes.
使用三种类型的电极对咽部肌肉组织进行了31项肌电图研究。根据专门为咽部制定的标准对电极特性进行了比较；详细描述了电极定位技术；并讨论了进行这些研究时遇到的技术困难。针电极最适合分析单个电位。为了分析肌电活动的时间，我们更喜欢使用钩状线电极（用于腭咽肌或环咽肌）或双极吸引电极（用于咽缩肌）。咽部肌电图在技术上是可行的，并且在研究正常和病理过程中具有一定作用。
