Objective:
The main objective of this study is to check the correlation between vocal self-assessment and results of the Voice-Related Quality of Life (V-RQOL) protocol, and whether there is a correlation between perceptual vocal assessment made by voice therapists and the results from the V-RQOL protocol.
Study Design:
The study included 245 subjects with vocal complaints. This was a prospective analytical clinical study.
Methods:
Vocal perceptual assessment of each subject with dysphonia was made by three voice therapists, followed by self-assessment made by the subjects themselves, and the application of the V-RQOL protocol.
Results:
The results have shown poor level of agreement between vocal assessment made by the voice therapists and self-assessment made by the subjects. The statistical analysis indicated that the results of V-RQOL protocol showed significant correlation with the vocal assessment made by the voice therapists and the self-assessment by the subjects.
Conclusions:
The agreement between the assessments was low and variable; age, gender, professional voice use, and clinical laryngoscopic diagnosis did not influence the agreement level. Protocol V-RQOL is sensitive to vocal assessment made by the voice therapists and self-assessment made by the patient.

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