Summary
This review found evidence supporting specific voice measures for clinical assessment of voice disorders. However, more high-quality research is needed for a comprehensive standard evaluation.
Area of Science:
- Communication Sciences and Disorders
- Otolaryngology
- Speech-Language Pathology
Background:
- Voice disorders affect a significant patient population.
- Accurate clinical assessment is crucial for effective diagnosis and treatment.
- Evidence-based practice necessitates a review of existing research on diagnostic tools.
Purpose of the Study:
- To systematically review existing research evidence supporting the use of various voice measures in the clinical assessment of patients with voice disorders.
- To identify which voice measures have sufficient evidence for inclusion in standard clinical practice.
Main Methods:
- A comprehensive literature search was conducted across 29 databases for English-language articles published between 1930 and 2009.
- Keywords included objective and subjective voice measures, voice disorders, and diagnostic accuracy.
- Articles were critically appraised by a committee using a modified rating system for diagnostic evidence.
Main Results:
- One hundred articles met the inclusion criteria.
- Acoustic measures were the most frequently investigated (60%).
- Only 17 out of 100 articles provided adequate evidence for formal consideration in clinical voice assessment.
Conclusions:
- Selected acoustic, laryngeal imaging, auditory-perceptual, functional, and aerodynamic measures show promise for clinical voice evaluation.
- There is a significant need for further high-quality research to establish a comprehensive set of standardized methods.
- Evidence-based recommendations for a complete clinical voice evaluation are currently limited.

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

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
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:

01:30Assessment of Airway, Skin Color, and Use of Accessory Muscles
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

01:25Assessment of the Cardiovascular System IV: Auscultation
Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.

01:27Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.
