概括
语音值功率 (PTW) 有效地识别了喉无能,特别是在功能低下的语音障碍中. 在量化不完整的关闭时,PTW显示出比声声值压力 (PTP) 和声声值流量 (PTF) 更高的灵敏度.
科学领域:
- 喉科和声音科学 喉科和声音科学
- 语音病理学和声学研究
背景情况:
- 气动力学测量,如声声值压力 (PTP),声声值流量 (PTF) 和声声值功率 (PTW) 已被提议用于量化部无能.
- 了解这些空气动力学测量和 incomplete glottal closure 的程度之间的关系对于诊断和管理语音障碍至关重要.
研究的目的:
- 调查PTP,PTF和PTW在反映不同程度的语音障碍患者中不完全关闭的有效性.
- 为了比较这些空气动力学测量的诊断准确度,在区分不同类型的喉无能症之间.
主要方法:
- 参与了30名喉无能症患者 (10名低功能,20名高功能) 和30名对照人群.
- 测量了PTP,PTF和PTW,PTW计算为PTP × PTF.
- 不完全的喉关闭被量化使用正常化喉间隙 (NGG) 和正常化喉间隙面积 (NGGA) 来自视频玻璃镜分析.
主要成果:
- 在三个组 (低功能的,高功能的,对照组) 中观察到PTP,PTF和PTW的显著差异,低功能的组的值更高.
- 接收机运行特征 (ROC) 分析表明了很好的分类准确性,特别是PTW,在区分低功能的和对照组 (曲线下的面积= .717.757).
- 在功能低下和整体障碍组中,在气动力学测量 (特别是PTW) 和喉间隙参数 (NGG,NGGA) 之间发现了强烈的正相关性.

Larynx
1.3K
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,...

Physical Assessment of the Respiratory Tract IV: Auscultation
279
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Physical Assessment of the Respiratory Tract II: Palpation
236
Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...

Assessment of Ventilation II: Respiratory Depth and Rhythm
1.4K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
