Abstract The aim of this study was to verify and compare vocal, respiratory and transverse abdominal muscle activation measurements before and after a physiotherapeutic protocol for intensive training of the body force center musculature in a voice professional. A 21-year-old female journalist with no vocal complaint participated. Original, retrospective case report, approved by the Research Ethics Committee (nº 40680614.7.0000.5346). It was collected: sustained emission of /a/, /i/, /u/, /s/, /z/, /e/ and the counting of numbers in usual pitch and loudness, of /e/ voiceless, of Modal Sound Pressure, dynamic and sung extension, maximal respiratory pressures, forced vital capacity and transverse abdomen activation, by means of a sphygmomanometer with a pressure biofeedback unit. Afterwards, a physiotherapeutic protocol for intensive training of the body force center and reevaluation was applied.Emissions support, modal and minimum Sound Pressure Level, sung extension, maximal respiratory pressures and activation of the transverse abdomen increased; and there was a reduction in the maximum Sound Pressure Level and the difference between the vowel average and the number count. Thus, intensive physical therapy training at the body strength center improved respiratory control and pneumophonoarticulatory coordination.

Introduction: Education professionals are one of the most important occupational groups and represents one of the main parts of the economy of modern society. The vocal demands most mentioned by the teachers are talking while standing up, talking a lot and in a closed environment, which corresponds to the most frequent situations encountered in teaching. In addition, remaining in the standing position for a prolonged period may have repercussions on other systems and generate postural deviations, pain and reduced functionality. Objective: To verify changes in pressure pain threshold, in disability index and in craniocervical posture of female teachers with vocal and musculoskeletal complaints, and with normal larynx, after myofascial release - pompage. Methods: This study was a controlled and randomized clinical trial. The following procedures were performed: anamnesis, videolaryngoscopy, hearing screening, clinical and photogrammetric postural assessment using the SAPo® protocol, completion of the neck pain self-assessment protocol Neck Disability Index, and pain threshold in the cervical muscles using the Pain Pressure Threshold. Myofascial therapy with pompage had a total of 24 sessions of 40 min each, three times a week, in 28 teachers assigned to the study group (SG), and 28 to the control group (CG). Afterwards, the groups were reassessed. Results: The SG presented a significant improvement in the pain threshold of all the muscles evaluated, in the posture of most of the body segments evaluated, and in the cervical disability. In the CG there was a significant improvement in angle A2 after therapy. Conclusion: After myofascial release therapy with pompage, the subjects presented a reduction in cervical pain and in functional disability, an increase in pain threshold, and posture improvement.

The adequate respiratory support ensures resonance, projection, focus, stability, and better vocal quality. The aim of this study was to verify the relationship between the activation of the core musculature and the spectrographic acoustic vocal characteristics in a group of adult women. This is a cross-sectional, observational, analytical, and quantitative study with ten women 19 to 28 years old, without vocal complaints, and without laryngeal disorders. Spectrographic vocal analysis, maximum expiratory pressure measurement, and evaluation of the multifidus, transverse and perineum muscles were performed. The data were analyzed using the Spearman Correlation Test at 5 %. The results showed significant positive correlation between the maximum expiratory pressure and the definition of the second formant; between the activation of the perineal muscle and the regularity of the spectrographic tracing. And showed significant negative correlation between the activation of the multifidus muscles and the width of the second formant. It was concluded that the more activated the perineal musculature, the greater the regularity of the spectrographic tracing; the higher the maximum expiratory pressure, the greater the definition of the second formant; and the greater the activation of the multifidus muscles, the smaller the bandwidth of the second formant. Such findings demonstrate the role of the core strength in the vocal quality. A relationship was established among the maximum expiratory pressure, the activation of the core muscles, and the spectrographic vocal characteristics.

The objective of this study was to verify the vocal measurements of athletes from an american football team from a municipality in the countryside of the state. With participation of eight men, aged between 18 and 39 years old (average of 24.25 years old). The collection of maximum phonation time of the vowels /a/, /i/, /u/, /s/, /z/, /e/ and number counting in normal pitch and loudness and the maximum phonation time of the [ė] was performed. Modal Sound Pressure Level and dynamic range were obtained by emission of /a:/. Acoustic evaluation of glottal and spectrographic sources. Maximum phonation times were below normality; the s/z ratio within the normality; the ratio ė/e below normality; the difference between vowels and number counting, the modal sound pressure level and the dynamic range were above normality. The acoustic vocal analysis showed impairment of the glottic source while the spectrographs were considered normal. In these American football athletes, pneumo-phono-articulatory incoordination with hyperfunctional characteristics and acoustic signal with presence of instability, aperiodicity and vocal emission failures were found, probably due to the incorrect vocal uses practiced in the sport.

The objective of the work was to characterize the aerodynamic vocal measurements of professional singers according to gender and the reference values. This is a cross-sectional, quantitative and retrospective study with 23 professional singers between 19 and 55 years old. The maximum phonation times of /a/, /i/, /u/, /s/, /z/, /e/, /ė/; sound pressure levels; and s/z and ė/e ratios were analyzed. The data were analyzed statistically. Men showed maximum phonation time of /e/, /i/ and /u/ significantly below the reference values and women showed significantly lower values of the maximum phonation time of /e/, and maximum phonation time of /i/ e /u/ significantly within the expected. The usual sound pressure level and maximum sound pressure level were significantly higher than the reference values in both genders. It was concluded that, in the group of professional singers analyzed, the results of the maximum phonation time suggest greater incoordination in the respiratory and laringeal control of the prolonged emission in men. The results of sound pressure level suggest greater vocal effort in the emission for both genders, or adjustments due to the muscular training inherent to the profession.

Objetivo: investigar o efeito do treinamento fisioterapêutico intensivo do centro de força corporal sobre medidas vocais acústicas de cantores populares. Métodos: Quinze cantores populares profissionais adultos, divididos em grupo de estudo e grupo de controle, realizaram avaliação vocal acústica antes e após o treinamento fisioterapêutico intensivo do centro de força corporal. Os resultados foram comparados estatisticamente. Resultados: O grupo de estudo apresentou aumento significativo do quociente de perturbação da amplitude suavizado e do coeficiente de variação da amplitude após o treinamento. Conclusão: No grupo de cantores populares profissionais adultos que recebeu treinamento fisioterapêutico intensivo do centro de força corporal, houve aumento de duas medidas de perturbação de amplitude ou shimmer que indicam instabilidade da pressão sonora e irregularidade da amplitude vocal ciclo-a-ciclo, evidenciando que o treinamento proposto não apresentou efeitos positivos sobre as medidas de fonte glótica dos cantores analisados.

Introduction: Altered body alignment may contribute to the onset of muscle hypertension in the cervical region. Alterations in the cervical region can generate several complications, including pain and hypertension during phonation. Objective: To relate the postural with functional alterations of the craniocervical region and the voice of women complaining of musculoskeletal pain in the cervical region. Methods: Case study with ten women complaining of cervical pain. Assessments: Craniocervical Dysfunction Index, photogrammetry, maximum vowel phonation time of the vowel /a/, and sound pressure level. Results: Craniocervical Dysfunction Index: 100% dysfunction. Maximum phonation time /a/: 100% decreased. There was a moderate significant positive correlation between these variables. Photogrammetry: all participants presented alterations in the calculated alignments. Sound pressure level: 90% altered. Conclusion: There were postural and functional dysfunctions in the craniocervical region and vocal alteration, suggesting that vocal imbalances are more related to functional than postural alterations of the craniocervical region.
