“…Vocal misuse and abuse associated with inadequate vocal adjustments and excessive muscle tension may increase the perception of symptoms, discomfort, and even trigger behavioral dysphonia. 11 , 12 , 13 , 14 Thus, the hypothesis of the present study was that the incorrect use of voice associated with wearing a face mask may also be associated with these consequences.…”

Objective To analyze the vocal self-perception of individuals who wore face masks for essential activities and those who wore them for professional and essential activities during the coronavirus disease pandemic. Materials and Methods This was an observational, descriptive, cross-sectional study. The study included 468 individuals who were stratified into two groups: the Working Group, comprising individuals who wore face masks for professional and essential activities during the pandemic; and the Essential Activities Group, with individuals who wore face masks only for essential activities during the pandemic. The outcome measures tested were self-perception of vocal fatigue, vocal tract discomfort, vocal effort, speech intelligibility, auditory feedback, and coordination between speech and breathing. Descriptive and inferential statistics were performed. Results Face masks increased the perception of vocal effort, difficulty in speech intelligibility, auditory feedback, and difficulty in coordinating speech and breathing, irrespective of usage. Individuals who wore face masks for professional and essential activities had a greater perception of symptoms of vocal fatigue and discomfort, vocal effort, difficulties in speech intelligibility, and in coordinating speech and breathing. Conclusion Use of face masks increases the perception of vocal symptoms and discomfort, especially in individuals who wore it for professional and essential activities.

“…Vocal use in inadequate ergonomic conditions, without prior vocal training, can be performed through incorrect muscle adjustments. Such adjustments, associated with excessive tension of the laryngeal musculature and scapular girdle region, can trigger an inappropriate vocal behavior 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 resulting in vocal fatigue symptoms 16 and musculoskeletal pain in regions close to the larynx 17 , 18 . It is also known that an inadequate body posture during vocal use is a predictor for the development of vocal changes 19 .…”

Objective: To investigate the self-perception of vocal fatigue symptoms and musculoskeletal pain in home office workers before and during the COVID-19 pandemic. Materials and methods: A total of 424 individuals participated in this cross-sectional, observational, and descriptive study; they were stratified into the experimental group (EG), consisting of 235 individuals working from home office during the COVID-19 pandemic; and the control group (CG), with 189 individuals who continued to work in person during this period. All participants answered the Vocal Fatigue Index (VFI) and the Musculoskeletal Pain Investigation Questionnaires. The data were analyzed in a descriptive and inferential manner. Results: Participants in the EG reported more vocal fatigue symptoms and musculoskeletal pain than those in the CG before the pandemic. However, during the pandemic, the EG presented a higher frequency of pain in the posterior of the neck, shoulder, upper back, and temporal and masseter muscles, while the CG presented a higher frequency of pain in the larynx. With regard to vocal fatigue, during the pandemic, EG had an increase in scores to factors such as tiredness and voice impairment, avoidance of voice use, and total scores. No such differences were noted in the CG. Conclusion: Workers who migrated to home offices during the COVID-19 pandemic are at risk of developing vocal disorders.

“…La EMGS se ha utilizado para evaluar los músculos laríngeos extrínsecos durante la masticación, la deglución, la voz y el habla, pero la discusión de los procedimientos para la normalización es controvertida y ha sido más discutida en estudios sobre las primeras dos funciones (Balata et al, 2015).…”

Resumen. En los últimos años ha habido un incremento del uso de la Electromiografía de Superficie en logopedia, lo que se evidencia en el número creciente de publicaciones en este área en revistas científicas. Este instrumento permite presentar de forma objetiva y precisa la actividad mioeléctrica en tiempo real, es no invasiva y se percibe de fácil aplicación. El objetivo de este trabajo es comparar la actividad mioeléctrica de los músculos maseteros, suprahioideos y esternoicleidomastoideos de cantantes con y sin entrenamiento vocal reglado a través de la Electromiografía de Superficie durante la realización de un fonetograma. La muestra estuvo conformada por 12 sopranos con edades entre 19 y 29 años, 6 con formación reglada en canto y 6 sin formación. Previo a la recogida de datos se calibró el sistema de análisis acústico a través de un calibrador y un dosímetro. Las muestras se recogieron en un gabinete insonorizado, previo consentimiento informado de los participantes. Se fijaron los electrodos en cada uno de los músculos, tanto derechos como izquierdos y se llevó a cabo el protocolo de registro de la actividad mioeléctrica. Se observaron diferencias estadísticamente significativas a nivel de los músculos esternocleidomastoideos, siendo mayor su actividad en los cantantes formados respecto a los no formados. No se obtuvieron diferencias significativas en los otros músculos estudiados. Puede concluirse que los cantantes con formación reglada presentan mayor actividad a nivel de músculos esternocleidomastoideos respecto a los no formados. Es necesario seguir investigando con muestras más amplias para llegar a resultados más concluyentes. Palabras clave: Electromiografía de Superficie; voz; canto; músculos orofaciales. [en] Singing voice and Surface Electromyography: A comparative study of muscle activity in trained and non-trained singers Summary. In recent years, there has been an increase in the use of surface electromyography in speech therapy, which is evidenced in the growing number of publications in this area in scientific journals. This instrument can be objectively and accurately presented myoelectric activity in real time, non-invasive and perceived easy to apply. The aim of this work is to compare the myoelectric activity of the masseter, suprahyoid and sternomicleidomastoid muscles of singers with and without vocal training regulated through surface electromyography, during the performance of a phonetogram. The sample consisted of 12 sopranos with ages between 19 and 29 years, 6 with singing training and 6 without training. Prior to data collection, the acoustic analysis system was calibrated through a calibrator and a dosimeter. Samples were collected in a soundproof studio, with prior informed consent of the participants. The electrodes were fixed in each of the muscles, both right and left, and the protocol for recording myoelectric activity was carried out. Statistically significant differences were observed at the level
