概括
半遮蔽声道 (SOVT) 练习为经历声疲劳的言语语言病理学家提供了立即的声乐改善. 虽然SOVT练习了增强的声学和感知措施,但需要进一步研究连接语音的有效性.
科学领域:
- 声音科学 声音科学
- 语音语言病理学 语言病理学
- 职业使用语音使用
背景情况:
- 语音疲劳是语音语言病理学家 (SLP) 之间普遍存在的问题,原因是要求高声任务.
- 高功能的语音条件需要对专业语音用户进行有效的干预.
研究的目的:
- 为了比较半遮蔽声道 (SOVT) 练习和声乐促进技术 (VFT) 对声乐疲劳的SLP声乐功能的直接影响.
- 强调多维语音评估,包括声学和听觉感知参数.
主要方法:
- 一个单盲随机临床试验,涉及26名SLP和语音疲劳的高级语音治疗学生.
- 参与者被随机分配到SOVT或VFT组,执行四种技术大约40分钟.
- 用单维 (,闪,HNR,CPPS) 和多参数 (AVQI,ABI) 声学测量,最大性能任务和听觉感知评估来评估声乐结果.
主要成果:
- SOVT练习显著改善了单维声学参数 (,闪,HNR) 并降低了听觉感知障碍症的严重程度.
- 与VFT组相比,SOVT组在和感知严重性方面表现出更大的减少.
- 在两组中都没有观察到多参数声学指数 (AVQI,ABI) 的显著变化,这表明连接语音评估的局限性.
结论:
- SOVT练习对声疲劳的SLP来说是一个有希望的短期干预措施,在声学和听觉感知测量方面显示出立即的好处.
- 虽然持续的母音分析显示了SOVT的显著变化,但连接的语音没有,突出了评估现实世界的声音功能的必要性.
- VFT技术可能需要更长的干预时间才能产生显著的效果;未来的研究应该探索使用多参数测量扩展治疗.

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:

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
265
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.

223
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.

202
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.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
