由于咽部横纹肌相对不易接近，直到最近才尝试括约肌肌电图检查。尽管如此，大量的数据已经出现在吞咽过程中，沿着肌肉动作。在大多数这些材料中，没有对所涉及的肌肉中的事件顺序进行实际客观的记录。最近，吞咽机制和咽部修复手术的实际兴趣的复苏使得咽肌电描记术成为必要。因此，Doty和Bosma（'56）对麻醉猴、猫和狗的口、咽和喉区域的反射性吞咽进行了肌电图研究。Broadbent和Swinyard（'59）随后在对腭裂患者进行手术期间的麻醉下进行了类似的研究。从本研究开始，我们认为我们不仅要检查麻醉下的反射性吞咽，而且要检查尽可能正常的条件下的吞咽。因此，我们被迫为此设计各种程序，包括广泛的解剖。我们目前的报告涉及我们的肌电图研究在兔子，并遵循我们的早期报告（Dutta和Basmajian，'60）的总体和微观形态的兔子的咽肌。稍后的报告（准备中）将涉及我们最近完成的对有意识的正常人的肌电图研究。
In view of the relative inaccessibility of the striated muscles of the pharynx, electromyography of the sphincters has not been attempted until recently. Nonetheless, considerable data have appeared on the process of swallowing along with references to muscular action. In most of this material, no actual objective recordings of the sequence of events in the involved muscles were made. The recent resurgence of practical interest in the mechanism of swallowing and in the reparative surgery of the pharynx has made a bold approach to pharyngeal electromyography a necessity. Thus, Doty and Bosma ('56) performed electromyographic studies of reflex swallowing in the areas of the mouth, pharynx and larynx of anesthetized monkeys, cats and dogs. Broadbent and Swinyard ('59) then made similar studies under anesthesia during operations on human patients with cleft palate. From the start of the present study, we felt that we must not only examine reflex swallowing under anesthesia, but also swallowing under conditions as normal as possible. Therefore we were forced to devise various procedures towards that end, including extensive dissections. Our present report deals with our electromyographic studies in rabbits and follows our earlier report (Dutta and Basmajian, '60) on the gross and microscopic morphology of the rabbit's pharyngeal muscles. A later report (in preparation) will deal with our recently completed electromyographic studies on conscious, normal human beings.
