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概念，开发新的肌电图程序，用于中风患者使用腭提升假体的体能训练。本文获得的结果如下： 1．对患有腭咽功能不全的中风说话者进行身体训练的原型程序被应用于两名中风说话者志愿者。该程序持续了两个月，并根据过去的研究制定了方案。两名说话人在知觉检查中言语结果发生了显着变化。 2．提肌腭大肌活动（％峰值提肌活动）以双极方式排列；对于某些语音，该范围估计接近可能最大活动水平的 100%，而对于其他声音，该范围则为零或更低。3。语音中双极方式的特征没有趋势。即使对于每个受试者相同的语音，双极性方式的方面也是可变的。4．平滑的提腭帆肌活动在PLP到位时往往趋于稳定，但其随言语产生次数的变化而变化。5．通过 MPF（平均功率频率）6 的 FFT 分析，发现放置 PLP 可降低提腭大肌的疲劳性。 LVP 肌肉肌电图的总体结果表明，配备 PLP 的扬声器可以显示出与正常扬声器类似的结果。这些与 PLP 放置相关的发现也与腭裂说话者相似。实验证明 CPAP 可以在 PLP 条件下激活上睑提肌活动。一些对诱导 CPAP 表现出积极反应的患者被认为是使用 PLP 进行家庭 CPAP 治疗的候选者。家庭 CPAP 治疗的反应在候选者之间存在差异：年轻和/或治疗后管理良好的受试者表现出显着的反应。中风发作
