          Abstract

          RESUMO Objetivo Analisar a percepção de fadiga em professores universitários, de acordo com o nível de conhecimento sobre saúde e higiene vocal. Métodos Estudo observacional, transversal e analítico. Participaram 235 professores universitários, divididos em: Grupo 1 (G1) - 201 professores universitários, com maior conhecimento sobre saúde e higiene vocal; Grupo 2 (G2) - 34 professores universitários, com menor conhecimento sobre saúde e higiene vocal. Os participantes responderam ao instrumento Índice de Fadiga Vocal (IFV). Os dados foram analisados utilizando-se o teste de Mann-Whitney (p<0,05). Resultados Professores universitários do G1 apresentaram percepção de fadiga significativamente maior que os professores universitários do G2, nos domínios fadiga e restrição vocal (p=0,010) e recuperação com repouso vocal (p=0,039). Conclusão Professores universitários com maior conhecimento sobre saúde e higiene vocal apresentam maior percepção da fadiga vocal.

          ABSTRACT Purpose To analyze the perception of fatigue in university professors, according to their level of knowledge of vocal health and hygiene. Methods Observational and cross-sectional study. The study counted with 235 university professors, divided into two groups: Group 1 (G1) - 201 professors with more knowledge of vocal health and hygiene; Group 2 (G2) - 34 professors with less knowledge of vocal health and hygiene. The participants answered to the Vocal Fatigue Index (VFI). The data were analyzed using the Mann-Whitney test (p<0.05). Results The G1 presented significantly higher fatigue perception than G2 in the factor of tiredness of voice and avoidance of voice use (p = 0.010) and improvement of symptoms with rest (p = 0.039). Conclusion Professors with more knowledge of vocal health and hygiene have higher perception of vocal fatigue.

            Factors predicting patient perception of dysphonia caused by benign vocal fold lesions.

            To assess factors that may be predictive of patient perception of dysphonia severity, as quantified by the Voice Handicap Index (VHI) score. We hypothesize that 1) level of vocal demand; 2) auditory-perceptual evaluation of dysphonia severity; and 3) vocal function, as defined by phonatory glottal closure and mucosal wave vibration, are the most significant predictors of VHI score. : Retrospective review of 100 patients with benign vocal fold lesions. Variables assessed for predictive value to VHI score are level of vocal demands, auditory-perceptual evaluation of dysphonia severity, integrity of mucosal wave vibration and phonatory glottal closure, lesion type, duration of current complaint, smoking, age, and sex. Harmonic to noise ratio was assessed in a subset of 50 patients. Patients with routine voice use had significantly lower VHI scores than those with more intensive (nonsinging/acting) vocal demands. Patients who quit smoking had greater VHI scores than those who currently smoke or never started. Patients with long-standing dysphonia tended to have lower VHI scores than those with shorter duration vocal complaints. Auditory-perceptual assessment of dysphonia severity and harmonic to noise ratio were weak predictors of VHI score. Age, sex, lesion type, phonatory glottal closure, and mucosal wave vibration were not significant predictors of VHI score. Patient perception of dysphonia severity is independent of many factors commonly assessed during the evaluation of voice disorders. It appears to be an important independent element in the assessment of the effect of a benign vocal fold lesion and critical to therapeutic decision-making.
