项目摘要
Purpose : This research was conducted to clarify crucial factors in construction procedure of a speech appliance to decrease muscle fatigue, which prevent speakers from performing continuous speech.Methods and Subjects : 1998 : Experimental speech appliances with variable portion of a palatal lift prosthesis were constructed. Electromyography of the levator veli palatini muscle during speech tasks was recorded when each type of experimental speech appliances was removed and inserted. Five normal speakers were selected as subject in the study of 1998. 1999 : Each subjects was instructed to perform 200 productions of/pu/when respective speech appliances were inserted and removed. In each experimental condition, levator EMG was recorded. Mean power frequency (MPF) were calculated on the basis of Fast Fourier Transfer (FFT) so as to examine 1) whether s speech appliance can decrease the muscle fatigue, 2) what type of a portion of a palatal lift prosthesis can decrease most effectively.Res … More ults : 1) Change in reserve capacity for velopharyngeal function for speech, which is defined as differential activity between levator activity during speech tasks and possible maximum activity, was greater in association with alteration of length and angle of a velum portion of an experimental palatal lift prosthesis than the condition of alteration of width of the appliances. That is, when the velum is elevated up to the level of the palatal plane, reserve capacity could become greater than any other vertical positions. 2) For normal speakers, the effect of a speech appliance to decrease levator muscle fatigue during 200 continuous productions of/pu/was not different between placement and removal conditions. On the other hand, in case of speakers with cleft palate with velopharyngeal incompetence, subjects, who showed greater increase in reserve capacity for speech in association with placement, exhibited greater decrease in muscle fatigue. Conclusion : The results obtained here can suggest that a palatal lift prosthesis which can elevate the velum up to the level of the palatal plane could decrease muscle fatigue most effectively, which might enable speakers to perform continuous speech production without collapse in velopharyngeal function. The effect might be more remarkable in speakers, for whom decrease in required levator muscle activity is marked in association with placement of the appliance. Less
目的:进行了这项研究是为了阐明语音设备的施工程序中的关键因素,以减轻肌肉疲劳,从而阻止说话者进行连续的语音。方法和受试者:1998年:构建了带有palatal升力假体的可变部分的实验语音用具。删除并插入每种类型的实验语音器具时,记录了语音任务期间左旋杆菌肌肉肌肉的肌电图。在1998年的研究中,选择了五名普通话者作为受试者。1999年:指示每个受试者在插入并删除相对语音用具时执行200份/pu/的作品。在每种实验条件下,记录了弹刀EMG。根据快速傅立叶转移(FFT)计算平均功率频率(MPF),以检查1)S语音设备是否可以减少肌肉疲劳,2)2)palatal升力假体的一部分类型最有效地减少。RES可以最有效地减少……更大的ults…ults:更大的言论能力在言语中的言论范围更大,并且在velopharyngeal的活动范围内的活动范围更大,并且在velopharyngeal的活动中的行为范围更大,并且可能会导致范围的活动,从而既有行为又可能会导致范围的行为,从而使范围内的范围更加不同。随着实验性pa升起假体的长度和角度的变化,而不是电器宽度改变的条件。也就是说,当绒毛升高到pallath平面的水平时,储备容量可能会比任何其他垂直位置都更大。 2)对于普通扬声器,语音设备在200次连续生产过程中减少悬浮器肌肉疲劳的影响在放置条件和去除条件之间没有差异。另一方面,如果有咽咽cle裂的说话者,受试者表现出更大的储备储备能力增加,与放置相关的言语能力增加,则肌肉疲劳的降低更大。结论:这里获得的结果可能表明,可以将绒毛升高到pa骨平面水平的palatal升力假体可以最有效地降低肌肉疲劳,这可能会使扬声器能够在不连续的语音产生中而不会在速咽功能中崩溃而进行连续的语音产生。在说话者中,这种效果可能会更加引人注目,因为所需的左右肌肉活动的减少与设备的放置相关。较少的
