ObjectivesThe study aims to investigate the vocal fatigue symptoms and laryngeal status in relation to vocal activity limitations and vocal participation restrictions.Study DesignThis is a case-control study.MethodsTwo hundred six teachers were divided into two groups based on the frequency of their self-reported vocal symptoms being more or less than the mean of reported frequency. The study compared odds for activity limitation and participation restriction in relation to frequency of vocal symptoms, number of vocal symptoms recurring weekly, and organic laryngeal changes. Activity limitation and participation restriction were studied using the Voice Activity and Participation Profile questionnaire.ResultsIncreased odds were found for teachers with frequent vocal symptoms and especially those with one or more vocal symptom recurring weekly. Odds were found to be 2.6–8.5 times more likely in teachers with more frequent vocal symptoms. The odds increased dramatically with increase of the number of vocal symptoms recurring weekly. Laryngeal organic changes were found to increase the odds but insignificantly.ConclusionsTeachers with frequent vocal symptoms, especially those with vocal symptoms recurring weekly, have increased odds ratio for vocal activity limitation and vocal participation restrictions. High scores or frequent occurrence of self-reported vocal fatigue symptoms must be taken seriously in the evaluation of vocal working ability.
