Summary
Understanding vocal hyperfunction etiology is key. Phonotraumatic Vocal Hyperfunction (PVH) is linked to gradual voice use, while Non-Phonotraumatic Vocal Hyperfunction (NPVH) has varied causes like voice use, stress, or infections.
Area of Science:
- Laryngology
- Voice Science
- Speech-Language Pathology
Background:
- Hyperfunctional voice disorders require better understanding of their causes for improved care.
- Etiological factors influencing Phonotraumatic Vocal Hyperfunction (PVH) and Non-Phonotraumatic Vocal Hyperfunction (NPVH) are not fully elucidated.
Purpose of the Study:
- To estimate the prevalence of etiological factors in PVH and NPVH.
- To analyze self-reported disorder onset data from a large patient cohort.
Main Methods:
- Retrospective chart review of 1,577 PVH patients and 979 NPVH patients.
- Extracted self-reported onset rate (gradual/sudden) and associated events (voice use, anxiety/stress, URI).
Main Results:
- Both groups predominantly reported gradual onset.
- Voice use was the most common factor for PVH; NPVH showed equal frequency for voice use, anxiety/stress, and URI.
- PVH subgroups were linked to voice use, while NPVH subgroups showed distinct associations with single factors.
Conclusions:
- PVH is strongly associated with accumulated phonotrauma, aligning with clinical views.
- NPVH presents a more heterogeneous etiology.
- Identified subgroups may inform tailored treatments and outcome investigations.

01:21Larynx
3.6K
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,...

01:18Factors Affecting Illness
4.9K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
1.2K
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:

01:25Factors Affecting Perception
2.4K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
1.7K
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.
