项目摘要

The study was aimed to establish concepts to develop new procedure of electromyography in a physical training for stroke patients with a palatal lift prosthesis.The results obtained here as follows :1. A prototypic procedure for physical training for stroke speakers with velopharyngeal incompetence was applied for two volunteers of stroke speakers. The procedure was continued by two months with a protocol established on the basis of past studies. Two speakers showed marked change in speech outocome in perceptual examination.2. Levator veli palatini muscle activity (% peak levator activity) was ranged in bipolar manner ; For some speech sounds, the range was estimated to be closed to 100% of the possible maximum activity level while for other sounds it was no or less.3. There was no tendency in the characteristics of bipolar manner across speech sounds. The aspect of bipolar manner was variable even for same speech sounds for each subject.4. The smoothed levator veli palatini muscle activity was tended to be stabilized with a PLP in place while it was variably changed in association with number of production of speech.5. The fatigability of the levator veli palatini muscle was identified to be decreased by placement of a PLP by mean of FFT analysis of MPF (Mean Power Frequency)6. Overall findings of EMG of LVP muscle indicated that speakers furnished with a PLP could show similar findings to normal speakers. These findings in association with placement of a PLP were also similar to speakers with cleft palate. Experimental CPAP was proved to activate levator muscle activity in the condition of a PLP. Some patient showing active response to induced CPAP was indicated to be candidate for home treatment of CPAP with a PLP in place.The response of home CPAP therapy was variable across candidates : Significant response was showed by subjects with young age and/or good management after onset of stroke

本研究的目的是建立一种新的肌电检测方法，用于脑卒中患者腭部提升修复后的运动训练。一个原型程序的身体训练中风扬声器与下咽功能不全，适用于两名志愿者的中风扬声器。该程序持续了两个月，并根据过去的研究制定了一项方案。两个说话人在知觉测试中表现出明显的言语输出变化.腭帆提肌活动（提肌峰值活动%）以双极方式变化;对于某些语音，估计范围接近可能的最大活动水平的100%，而对于其他语音，估计范围为零或更小。双极性方式的特征在不同语音中没有明显的倾向性。双极方式的方面是可变的，即使是相同的语音，每个被试。腭帆提肌的平滑活动随着PLP的就位而趋于稳定，而随着言语产生次数的增加而变化。通过MPF（平均功率频率）6的FFT分析，确定通过放置PLP降低腭帆提肌的疲劳性。LVP肌肌电图的总体结果表明，扬声器与PLP配备可以显示类似的结果，正常的扬声器。与PLP放置相关的这些发现也与腭裂患者相似。实验证明，在PLP条件下，CPAP可激活提上睑肌活动。一些对诱导CPAP有积极反应的患者被认为是家中使用PLP进行CPAP治疗的候选人。家庭CPAP治疗的反应在候选人之间是可变的：年轻和/或卒中后管理良好的受试者表现出显著的反应
