    Estudo controlado sobre a produção da voz cantada em pacientes com Doença de Parkinson
    (Universidade Federal de São Paulo (UNIFESP), 2019-11-28) Ferreira, Michelle de Melo [UNIFESP]; Oliveira, Maria Gabriela Menezes de [UNIFESP]; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4723159U8; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4329969Z7; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Parkinson's disease (PD) is characterized not only by bradykinesia, stiffness and tremor, but also by impairments in voice and speech at different procedural levels. Recent studies have shown that music may not only aid gait but may have a similar effect on vocal behavior. However, it is not yet clear to what extent memory could interfere with the sharpness of the chanting by biasing such results. It is also unknown whether singing can be affected by the disease since speech and singing have some independent neural networks. Objective: To compare vocal production between speech and singing and to investigate if there is difference in the different cognitive abilities involved in singing between individuals with Parkinson's disease and healthy people. Method: In the present study, twenty patients with Parkinson's disease were compared with twenty healthy controls matched by sex, age and schooling with musical experience as closely as possible. A series of tests was applied to evaluate vocal abilities in speech and singing, sound-musical perception and short and long-term musical memory. Results: Speech tasks did not differ in the direction of prosodic intonation, but the magnitude of this variation was significantly lower in the DP group than in the control group. The vocal range was also reduced in the spoken voice and in the glissando due to the difficulty of emitting higher frequencies. When it was evaluated the vocal performance in the song "Happy Birthday" without accompaniment it was possible to observe a difficult melodic direction whereas in the condition with accompaniment this did not happen. The acuity of the intervals was similar between the groups and the Vocal Imitation Test showed no group differences. Discussion: The impairments on spoken voice may also reflect on sung voice. However, singing with accompaniment of a musical instrument or with another voice can aid in the vocal acuity of notes, intervals and melodic outlines. Conclusion: The results found in the present study suggest that the accompanying singing can be used as an intervention tool to improve voice and speech impairments in this population.

    Impacto imediato após demanda vocal no cantor de teatro musical
    (Universidade Federal de São Paulo (UNIFESP), 2017-02-24) Pacheco, Claudia de Oliveira Lima Camargo [UNIFESP]; Behlau, Mara Suzana [UNIFESP]; http://lattes.cnpq.br/2274436726620746; http://lattes.cnpq.br/7485525730547312; Universidade Federal de São Paulo (UNIFESP)
    Objectives: Evaluate the immediate impact of vocal demand in musical theatre singers and explore its relation with the presence of vocal signs and symptoms. Methods: 264 singers/actors with ages from 18 to 72 and mean age of 33 years old took part in this research. 126 were female and 138 were male. All participants were currently performing musical theatre singers when the data was collected. All of them answered two questionnaires immediately after the performance. The first questionnaire was composed by 24 questions and was designed with the purpose of collecting information about identification, voice self-assessment and detailed explanation of the actors' characteristics, besides finding out the existence of vocal symptoms. The second one, Evaluation of the Ability to Sing Easily - EASE translated and culturally adapted to Brazilian Portuguese as EASE-BR. EASE-BR explores vocal fatigue features, pathologic-risk indicators and vocal concern after using the voice professionally. We have studied the relationship between the demographic data and the vocal use with the answers from EASE-BR. Results: Singers showed a low mean of 1.56 vocal symptoms being frequent throat clearing (50,76%) and chronic throat dryness (26.52%) the most mentioned ones. There was no significant difference in relation to age, number of practicing hours, singing lessons according to the total scores and subscales of EASE-BR. Artists with longer singing practice showed lower values at total scores and subscales of EASE-BR. Singers who have been singing opera and vocal solo besides musical theater presented lower values at total scores and subscales of EASE-BR. The ones with a higher number of vocal symptoms obtained higher scores both EASE-BR and subscales’. There was a fragile correlation between EASE-BR and vocal symptoms. The test-retest showed good reproduction. Conclusion: The data showed that singers evaluate the impact of vocal demand positively and considered their voices apt to a new performance. EASE-BR proved to be useful to identify vocal changes and it has a weak association with the presence of vocal symptoms.

    Processamento auditivo central em cantores como queixa de dificuldade de produção de sons agudos
    (Universidade Federal de São Paulo (UNIFESP), 2019-12-18) Mesquita, Loriane Gratao De [UNIFESP]; Biase, Noemi Grigoletto De [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Central auditory processing has a strong correlation with the correct production of musical sounds and can interfere with the performance of singers in case there is some intercurrence in this system. The complaint of the difficulty of production of sharp sounds referred by singers can have several causes, organic, functional vocal technique and even auditory. Objective: Analyse auditory abilities of singers complaining about the difficulty of producing sharp sounds. Methods: A total of 17 professional singers, both sexes, aged 18 to 40, were separated into two groups, one with 12 singers with specific complaints of difficulty in producing high sounds, and one group with 5 singers without vocal complaints. All participants underwent otorhinolaryngological, basic audiological and behavioural tests to evaluate competitive speech, distorted speech, and temporal processing. They also answered the questionnaire The Auditory Processing Domains Questionnaire. Results: The study group showed worse performance, statistically significant, in the competitive speech perception tests with: dichotic syllables, with monotonic listening sentences and alteration in the temporal processing test of short and successive pure tones of different frequencies, compared to the comparison group. In the questionnaire, the study group reported a higher number of complaints of listening in environments with competitive message, noise and temporal processing, with statistical significance. Conclusion: The auditory skills profile was worse in the group of singers with complaints than in the group of singers without complaints. The group with complaints presented alterations in the auditory ability of temporal ordering. This difference in auditory skills may contribute to the self-reported difficulty in producing high pitched sounds. An auditory skill enhancement can assist singers with this type of complaint. Further studies in this area should be conducted to better understand the involvement of auditory skills in the production of high pitched sounds.
