The present study describes technical prerequisites for soft palate reflex measurements and first results. Reflex measurements can be done using standard electromyographic methods. The data-processing system that records and processes the electromyographic signals was activated when the soft palate was stimulated by a newly developed device. The first results of objective soft palate reflex measurements in 15 healthy subjects show that the musculus levator veli palatini reacts to a mechanical stimulation of the soft palate with a contraction that can be measured electromyographically. The response latencies were constant in the individual subjects. In 12 subjects a minimum of 30 ms and a maximum of 61 ms was recorded. In one healthy subject, the reflex was activated only after 167 ms. No reflex could be evoked in two subjects. The stimulus was always supraliminal. Reaction time was longer following surface anesthesia of the oral mucosa.
本研究描述了软腭反射测量的技术前提及初步结果。反射测量可采用标准肌电图方法进行。当用一种新研发的设备刺激软腭时，记录和处理肌电信号的数据处理系统被激活。对15名健康受试者进行客观软腭反射测量的初步结果显示，腭帆提肌对软腭的机械刺激会产生收缩反应，这种收缩可用肌电图测量。各受试者的反应潜伏期是恒定的。在12名受试者中，记录到的最短潜伏期为30毫秒，最长为61毫秒。在一名健康受试者中，反射仅在167毫秒后被激活。两名受试者未诱发反射。刺激始终为阈上刺激。口腔黏膜表面麻醉后反应时间延长。
