概括
与典型发育的同龄人相比,患有脑 (CP) 的儿童表现出明显的语音运动控制差异,特别是在大声说话时口腔和喉功能. 两组人都适应了他们的语音机制,以增加声音的强度,从而有可能提高可理解性.
科学领域:
- 语音语言病理学 语言病理学
- 神经康复疗法 神经康复疗法
- 生物医学工程 生物医学工程
背景情况:
- 了解脑 (CP) 儿童的言语运动控制对于有针对性的干预至关重要.
- 在CP中,更大声的语音生产机制没有得到很好的描述.
- 这项研究研究了CP的儿童在更大声说话时的关节和喉调整.
研究的目的:
- 为了比较在口腔和喉子系统的语音运动控制差异,在更大声的语音生产期间,患有CP的儿童和典型发育 (TD) 同龄人之间.
- 在这些人群中阐明与增加的声力努力相关的特定动态和声学变化.
主要方法:
- 九名患有CP的儿童和九名TD同龄人参与了这项研究.
- 参与者在习惯和更大声的语言条件下产生句子.
- 光学运动捕捉记录了嘴唇和下巴的运动;声学分析评估了声功能.
主要成果:
- 与TD同龄人相比,患有CP的儿童表现出下运动减少,唇部运动改变,下速度减慢,唇部速度更快,关节间协调较差.
- 两组都增加了嘴唇/下巴运动,速度,时间协调和声功能 (增加了CPP,减少了光谱倾斜) 当大声说话时.
- 患有CP的儿童表现出减少的光谱倾斜和较低的头骨峰突出 (CPP) 整体.
结论:
- 与TD同龄人相比,患有CP的儿童在口腔和喉系统的言语运动控制方面表现出显著的差异.
- 这两组都修改了发音和喉行为,以产生更大声的语音,这表明一种补偿机制可能会增强可理解性.

Respiratory System Abnormal Finding II: Palpation and Auscultation
471
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Larynx
1.5K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Learning Disabilities
147
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
