Summary
A multidimensional voice protocol effectively diagnosed dysphonia by analyzing vocal function indicators. These indicators, including maximum phonation time and jitter, showed improvement after voice therapy and were maintained post-treatment.
Area of Science:
- Speech and Hearing Sciences
- Otolaryngology
- Voice Disorders Research
Background:
- Dysphonia diagnosis requires a comprehensive approach.
- Existing methods may not capture all essential vocal function data.
- A standardized protocol can improve diagnostic accuracy and prognosis.
Purpose of the Study:
- To develop and validate a multidimensional voice protocol for dysphonia diagnosis.
- To identify key indicators for assessing vocal function and treatment response.
- To evaluate the long-term effectiveness of voice therapy.
Main Methods:
- A multiparametric assessment (Multidimensional "Teatinos" Protocol) was used.
- Evaluated videolaryngostroboscopy, perceptual, acoustic, spectrographic, aerodynamic, and subjective measures.
- Compared 21 dysphonic patients with 21 controls, followed by a 3-month voice therapy intervention.
Main Results:
- Significant differences in vocal function indicators were found between groups.
- Key indicators sensitive to voice therapy included MPT, MET, MPTS, jitter, WB, SELF, HYGIENE, ANX, and perceptual/laryngoscopic/spectrographic findings.
- Therapeutic effects persisted or improved 4 months post-treatment.
Conclusions:
- The Multidimensional "Teatinos" Protocol effectively differentiates dysphonic patients from controls.
- Multidimensional voice evaluation is a valuable tool for diagnosing dysphonia.
- The protocol aids in assessing treatment efficacy and prognosis in clinical settings.

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:

01:26Modeling in Therapy
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

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.

01:21Larynx
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, corniculates, and...

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.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
