概括
在安静呼吸期间,特别是在呼吸结束时,假声 (FVF) 过度功能可以帮助区分原发性肌肉张力失声症 (pMTD) 与典型的语音. 这种FVF姿势可能是一个比发声模式更可靠的指标.
科学领域:
- 喉腔病理学 喉腔病理学
- 声音科学 声音科学
- 语言病理学 语音病理学
背景情况:
- 在发音过程中错误的声 (FVF) 过度功能是怀疑初级肌肉张力失声症 (pMTD) 的迹象.
- 然而,高功能的发音模式也存在于典型的扬声器中,使诊断复杂化.
- 这项研究研究了静静呼吸期间的FVF姿势作为潜在的差异化因素.
研究的目的:
- 测试静静呼吸期间的FVF曲率是否可以区分pMTD患者与典型扬声器.
- 评估FVF姿势作为高功能语音障碍的诊断标记.
主要方法:
- 来自30名pMTD患者和33名典型发言者的喉腔镜图像.
- 在静静的呼吸 (呼吸结束,最大吸入) 和声调任务中,使用新型曲率指数 (CI) 测量FVF曲率.
- 图像获取发生在30分钟的语音加载任务之前和之后.
主要成果:
- 在终期结束时,pMTD患者表现出凸的FVF轮 (平均CI为0.123),而对照组具有凸的轮 (平均CI为-0.093) (p=0.0002).
- 在最大吸入时,pMTD患者具有中性的FVF轮 (平均CI为0.012),对照组具有形轮 (平均CI为-0.155) (p=0.0002).
- 在持续发声或大声发音期间没有发现显著的FVF曲率差异,声载没有影响.
结论:
- 在平静呼吸期间的高功能FVF姿势,特别是在呼气结束时,可能是比声声相关的脑膜缩更显著的pMTD指标.
- 在安静呼吸期间的FVF曲率为原发性肌肉张力失声症提供了潜在的诊断生物标志物.

Respiratory System Abnormal Finding II: Palpation and Auscultation
559
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:

Physical Assessment of the Respiratory Tract II: Palpation
439
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.

Larynx
1.7K
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,...

Respiratory System Abnormal Finding I: Inspection and Percussion
323
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Physical Assessment of the Respiratory Tract III: Percussion
565
The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
