目的：本研究以正常说话者为研究对象，探讨机械上提腭veli muscle （LVP）的活动是否会直接影响腭veli muscle （LVP）。设计：每个受试者被要求在演讲任务中发出/mu/， /u/, /pu/， /su/和/tsu/，并尽最大努力吹。用实验腭提假体（PLP）在原位和移除时记录下LVP的平滑肌电图活动。参与者：4名正常说话者作为研究对象。结果：在所有受试者中，有PLP的所有任务的LVP活动都明显小于没有PLP的所有任务（p, 0.001；学生t检验）。方差分析(p，。001)澄清了LVP的活动范围在所有受试者的移除和放置条件下有显著差异。结论：结果与先前对腭咽功能不全患者佩戴PLP的结果相似。与放置PLP相关的LVP活性下降可能是由机械抬高的直接影响引起的，机械抬高减少了腭咽机制为完全关闭腭咽所必须移动的距离。
Objective: The purpose of this study was to examine whether mechanical elevation of the velum can directly affect the levator veli palatini muscle (LVP) activity using normal speakers as subjects. Design: Each subject was instructed to produce /mu/, /u/, /pu/, /su/, and /tsu/ in a speech task and to blow with maximum possible effort. Smoothed electromyographic activity of the LVP was recorded with an experimental palatal lift prosthesis (PLP) both in place and removed. Participants: Four normal speakers were used as subjects. Results: LVP activity for all tasks was significantly smaller (p , .001; Student’s t test) with the PLP in place than without the PLP for all subjects. An analysis of variance (p , .001) clarified that activity ranges of the LVP were significantly different between the removal and placement conditions for all the subjects. Conclusion: The result was similar to that previously obtained for patients with velopharyngeal incompetence wearing a PLP. It is possible that the decrease in the LVP activity in association with placement of a PLP is caused by the direct effect of mechanical elevation, which decreases the distance the velopharyngeal mechanisms must travel for complete closure of the velopharynx.
