“…The DSI of patients suffering from functional dysphonia was in the range of normal voices. Similar results were found in the literature [11,23] . In a group of 294 patients [23] , the median DSI values were statistically significant comparing voices with non-organic dysphonia (DSI = 2.0), vocal fold mass lesion (DSI = 1.2) and vocal fold paralysis (DSI = -0.7) with those of a control group (DSI = 4.2).…”

“…It is based on the weighted combination of important characterizing voice parameters: maximum phonation time, lowest intensity, highest frequency and jitter. The DSI is a valid instrument for distinguishing between pathological and non-pathological voices [14,23] and proved to be appropriate for clinical purposes [11-13, 16, 17] . It is also more sensitive to minimal changes [14] than perceptual measurements such as the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale, which was the basis for the DSI construction [14] .…”

Objective: This study focuses on the relation between objective voice quality and the self-perception of a voice handicap. Patients and Methods: The study group consisted of 86 German-speaking patients (51 women, 35 men) suffering from benign dysphonia. The test persons completed the German version of the Voice-Related Quality of Life (V-RQOL) Questionnaire without prior information about their diagnosis and underwent voice analysis with the Dysphonia Severity Index (DSI) being the parameter of this study. Results: No correlation between V-RQOL and DSI could be found (p > 0.05). On the V-RQOL, women scored worse than men, but not at a significant level. Patients with dysphonia of organic origin scored significantly worse than patients with functional dysphonia (p = 0.026). On the DSI, men’s values were significantly lower than women’s (p = 0.001). Organic dysphonia caused significantly lower DSI values than functional dysphonia (p = 0.011). Conclusion: Objective voice quality and the individual perception of voice quality by the patient are independent parameters. Both need to be assessed in clinical practice.

Background: Many studies have referred to the effects of age on voice and the consequences of these changes. However, only little is known about the adverse effects of voice changes on quality of life in the elderly. Objective: This study focuses on self-perception of voice in seniors as assessed by the Voice-Related Quality of Life (V-RQOL) questionnaire, on voice quality as measured by the Dysphonia Severity Index (DSI) and on the correlation between these parameters. Methods: V-RQOL and DSI were measured as previously described in 107 non-treatment-seeking test persons without voice complaints (76 women and 31 men; mean age 78.7 ± 6.8 years, range 66–94 years). Results: The mean V-RQOL value was 94.4 ± 9.8%. The mean value of the DSI in all participants was 1.2 ± 2.4. There was no significant correlation between the V-RQOL and DSI, either in women (p = 0.11), men (p = 0.58) or the whole study group (p = 0.26). Conclusion: Both the V-RQOL questionnaire and the DSI may be applied to seniors. As self-perception of voice and voice function do not correlate, both parameters have to be measured for voice assessment.

“…GRBAS applicability in voice area is broad and involves all kinds of voice disturbances, independent of etiology (8)(9)(10)(11)(12)(13)(14)(15) . It is a simple and fast evaluation method proposing the observation of five parameters: G (grade) -overall dysphonia grade; R -roughness, represented by hoarseness and harshness; B -breathiness; A -asthenia; S -strain.…”

OBJETIVO: Analisar o impacto de treino auditivo na avaliação perceptivo-auditiva da voz realizada por estudantes de Fonoaudiologia. MÉTODOS: Durante dois semestres, 17 estudantes que cursavam disciplinas teóricas de fonação (Fonação/Distúrbios da Fonação) analisaram amostras de vozes alteradas e não alteradas (selecionadas para este estudo), por meio da escala GRBAS. Todos receberam treinamento auditivo durante um total de nove encontros semanais, com cerca de 15 minutos de duração cada. Em cada encontro foi apresentado um parâmetro, por meio de vozes diferentes da amostra avaliada, com predominância no aspecto treinado. A avaliação das amostras por meio da escala foi realizada pré e pós o treinamento e em outros quatro momentos ao longo dos encontros. As avaliações dos alunos foram comparadas com uma avaliação de juízas, realizada previamente por três fonoaudiólogos, especialistas em voz. Para verificar a efetividade do treinamento foi usado o teste de Friedman e Índice de Concordância Kappa. RESULTADOS: O índice de acertos dos alunos no momento pré-treinamento foi considerado entre regular e bom. Observou-se manutenção do número de acertos ao longo das avaliações realizadas, para a maioria dos parâmetros da escala. No momento pós-treinamento observou-se melhora na análise da astenia, parâmetro enfatizado a partir das dificuldades apresentadas pelos alunos. Houve diminuição dos acertos no parâmetro rugosidade após este ter sido trabalhado de maneira segmentada em rouquidão e aspereza, e associado a diferentes diagnósticos e parâmetros acústicos. CONCLUSÃO: O treino auditivo potencializa as habilidades iniciais dos alunos, refinando-as para realização da avaliação, além de nortear ajustes em dinâmicas das disciplinas.
