The conditions of teachers' work during the COVID-19 pandemic affected teachers' lives regarding voice disorder and stress, even in emergency remote classroom situation.\u0000Objective. To analyze the relationship between the presence of voice disorder, job stress, and COVID-19 in teachers when in emergency remote classroom teaching situation at the time of the pandemic.\u0000Method. This is a primary, exploratory, observational cross-sectional study with the use of survey forwarded online during the period of emergency classes after the arrival of COVID-19 pandemic in Brazil. The teachers answered the sociodemographic questions about the presence of COVID-19 and the following instruments: Condition of Vocal Production-Teacher [Condição de Produção Vocal - Professor (CPV-P)], Screening Index for Voice Disorder (SIVD), and Job Stress Scale (JSS).\u0000Results. Of the 118 teachers analyzed, 94.1% were female; the average age was 44 years. The SIVD recorded the presence of voice disorder in 66.9% of the participants. Regarding the JSS, which are the findings related to stress at work in the demand domain, the teachers showed high levels, a fact which presupposes the existence of pressure of psychological nature to perform their work.\u0000Conclusion. The teachers self-reported the presence of voice disorder even in remote class situation, on the occasion of COVID-19, which were more common in older teachers. When comparing the presence of voice disorders, coronavirus symptoms, and stress domains in relation to demand, control, and social support, there was no significance. It is hoped that this study will help to reflect on the need to improve teachers' working conditions, strengthening work-related voice disorder actions and guiding actions for vocal care and well-being.","PeriodicalId":508578,"journal":{"name":"Revista de Investigación e Innovación en Ciencias de la Salud","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an effort to improve voice assessment practices and strengthen professional identity among speech-language pathologists in Quebec, Canada, a community of practice (CoP) was established, with the aim of promoting knowledge sharing, implementing change in clinical practice, and improving professional identity. Thirty-nine participants took part in the CoP activities conducted over a four-month period, including virtual meetings and in-person workshops. Participants had a high rate of attendance (> 74% participation rate in virtual meetings), and were highly satisfied with their participation and intended to remain involved after the project’s end. Statistically significant changes in voice assessment practices were observed post-CoP, regarding probability of performing assessments (p < .001), and perceived importance of assessment for evaluative purposes (p <.001), as well as improvements in assessment specific confidence, specifically for procedure of auditory-perceptual assessment (p < .001) and purpose of aerodynamic assessment (p = .05). Moreover, there was an increase in professional identity post-CoP (p < .001) and participants felt they made significant learnings. The present study highlighted the need to involve SLPs in future research to identify assessments that are relevant to the specific evaluative objectives of SLPs working with voice, and suggests CoPs are an efficient tool for that purpose.","PeriodicalId":508578,"journal":{"name":"Revista de Investigación e Innovación en Ciencias de la Salud","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vocal production models employing spring-mass-damper frameworks, precision in determining damping coefficients that align with physiological vocal fold characteristics is crucial, accounting for potential variations in the representation of viscosity-elasticity properties.\u0000Objective. This study aims to conduct a parametric fitting of a vocal production model based on a mass-spring-damper system incorporating subglottic pressure interaction, with the purpose of accurately modeling the collision forces exerted by vocal folds during phonation.\u0000Method. A metaheuristic search algorithm was employed for parametric synthesis. The algorithm was applied to elasticity coefficients c1 and c2, as well as damping coefficients ε1 and ε2, which directly correlate with the mass matrices of the model. This facilitates the adjustment of fold composition to achieve desired physiological behavior.\u0000Results. The vocal system's behavior for each simulation cycle was compared to a predefined standard under normal conditions. The algorithm determined the simulation endpoint by evaluating discrepancies between key features of the obtained signals and the desired ones.\u0000Conclusion. Parametric fitting enabled the approximation of physiological vocal production behavior, providing estimates of the impact forces experienced by vocal folds during phonation.","PeriodicalId":508578,"journal":{"name":"Revista de Investigación e Innovación en Ciencias de la Salud","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the training and use of auditory perceptual evaluation of the voice reported by Colombian speech-language pathologists.\u0000Study Design. Cross-sectional observational research with a quantitative approach.\u0000Methods. A digital questionnaire was designed and distributed to gather information regarding professionals' training process and implementation of auditory-perceptual evaluation procedures. Descriptive statistics were applied, and several generalized linear models were adjusted to determine the influence of certain variables on others.\u0000Results. The survey received responses from 40 speech-language pathologists, revealing that the most used scales for training and evaluating vocal quality within this group are direct magnitude estimations (82.5% and 77.5%). Similarly, in this group, the tasks most frequently used to train and use as an evaluation strategy are vowel assessments (38%) followed by spontaneous speech (30%). Practitioners of this group were mostly trained using a conceptual framework involving multiple exposures to rating (42.5%). The use of direct magnitude estimation in training with a normal voice showed significance (p = 0.015), as did the use of the vowel /i/ in training with an equal-appearing interval (p = 0.013). The statistical models relating the scale used to the scale on which participants were trained were also significant (p < 0.05).\u0000Conclusions. The GRBAS scale is the training tool most used by the group of speech-language pathologists of the study group in Colombia. Future efforts should focus on improving training practices for auditory-perceptual evaluation, exploring alternative conceptual frameworks, and incorporating external references to enhance validity and reliability.","PeriodicalId":508578,"journal":{"name":"Revista de Investigación e Innovación en Ciencias de la Salud","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140489306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To present a simple form of vocal and breathing conditioning for voice professionals based on concepts from vocal science. The vocal conditioning program called Voice Athletes Conditioning uses the principles of exercise physiology to gradually improve vocal and respiratory overload to achieve endurance, power, and flexibility.\u0000Methods. Due to our personal experience with high voice users, we synthesized a vocal conditioning program (AVCP) that combines voice science, exercise physiology, sports science and physical therapy principles. This is an 8-week program of daily vocal and breathing exercises with overload enhancement each week using different types of breathing devices and semi-occluded vocal tract exercises, designed and developed according to the specific requirements and performance of the voice professional.\u0000Reflections. Professional voice users often experience episodes of vocal fatigue that can directly affect their performance and vocal health. As with physical training for athletes, voice exercises can also contribute to improving vocal conditioning, preventing voice disorders, as well as helping to obtain better performance, greater tolerance to fatigue and shorter recovery time.\u0000Conclusions. AVCP is an approach that considers the principles of muscle training aimed objectively at the respiratory and vocal muscles, carried out with a variety of breathing devices and specific vocal exercises in search of greater performance time, less physiological stress, and shorter recovery time in the professional use of the voice.","PeriodicalId":508578,"journal":{"name":"Revista de Investigación e Innovación en Ciencias de la Salud","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
