ResumoO objetivo deste estudo foi verificar e comparar as medidas vocais, respiratórias e da ativação do músculo transverso do abdome, antes e após um protocolo fisioterapêutico de treinamento intensivo da musculatura do centro de força corporal em uma profissional da voz. Participou uma jornalista, do sexo feminino, 21 anos de idade, sem queixa vocal. Relato de caso original, retrospectivo, aprovado pelo Comitê de Ética em Pesquisa (nº 40680614.7.0000.5346).2 Sonora modal, da extensão dinâmica e cantada, das pressões respiratórias máximas, da capacidade vital forçada e da ativação do músculo transverso do abdome, por meio do esfigmomanômetro com unidade de biofeedback pressórico. Após, foi aplicado um protocolo fisioterapêutico de treinamento intensivo do centro de força corporal e reavaliação. Houve aumento da sustentação das emissões, do Nível de Pressão Sonora modal e mínimo, da extensão cantada, das pressões respiratórias máximas e da ativação do transverso do abdome; e houve redução do Nível de Pressão Sonora máximo e da diferença entre a média das vogais e a contagem de números. Assim, o treinamento fisioterapêutico intensivo do centro de força corporal promoveu melhora do controle respiratório e da coordenação pneumofonoarticulatória.

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: The voice is heavily influenced by breathing and abdominal muscles. Objective: To verify the immediate effects of cervical stimulation and diaphragmatic release on the respiratory and phonatory function of adult women with no vocal complaints. Method: Relaxation maneuvers and eccentric work of the diaphragm were performed together with articulatory maneuver of the third cervical vertebra. Twenty-four women without vocal complaints, aged between 18 and 35 years were part of the intervention. All volunteers were submitted to an evaluation of respiratory muscle strength, maximum phonation time of the vowel /a/, sound pressure level and acoustic vocal analysis, before and after physiotherapeutic intervention. Statistical analysis consisted of the Student's t-test for independent samples and Spearman's correlation. Significance level was set at 5%. Results: There was a significant increase in the maximum phonation time of the vowel /a/ and in the modal sound pressure level. Regarding the acoustic analysis, there was a reduction in the standard deviation values of the fundamental frequency; in the smoothed pitch disturbance quotient; and in the fundamental frequency and amplitude variations. Conclusion: Cervical stimulation and diaphragmatic release improved vocal quality regarding duration of emission, sound pressure, and stability and noise of the glottic signal.
