Abstract
Introduction
Many teachers report discomfort and a decrease in the quality of aerodynamic, respiratory,
and cervical vocal aspects as well as of vocal self-assessment.
Objective
Characterize and correlate measurements of Sound Pressure Levels, Maximum Phonation
Time of /a/, Maximum Respiratory Pressures, Voice-Related Quality of Life and cervical
pain in teachers with vocal and musculoskeletal complaints and no organic vocal fold
lesions, and compare with normative values.
Methods
Retrospective study with 56 teachers. Anamnesis, video laryngoscopy, hearing screening,
measurements of sound pressure and maximum phonation time, and manovacuometry were
performed. Self-assessment protocols for Voice-Related Quality of Life and Neck Disability
Index were completed.
Results
there was significant higher Sound Pressure Levels; significant lower Maximum Phonation
Time of /a/, Maximum Expiratory Pressure, and total and physical scores of Voice-Related
Quality of Life; most participants had mild cervical disability; there was a negative
correlation between Maximum Expiratory Pressure and Neck Disability Index, between
Maximum Inspiratory Pressure and Maximum Sound Pressure Level, and between Neck Disability
Index and Voice-Related Quality of Life.
Conclusion
The results showed that there are damages and inadequacies in teachers’ vocal production
which affect their quality of life. Therefore, it is necessary to pay attention to
the conditions of use of the voice by professionals, and to their health education.
