Influência de alterações posturais, acompanhadas por fotogrametria computadorizada, na produção da voz

Abstract: INTRODUÇÃO: Há considerável evidência da importância de uma postura adequada para um bom desempenho vocal. As alterações posturais podem influenciar diretamente a projeção da voz. OBJETIVO: Identificar a influência das diferentes posturas corporais na produção da voz. MATERIAIS E MÉTODOS: Foram realizadas as análises de 25 amostras vocais de um indivíduo que emitiu a vogal sustentada /a/ em três diferentes posturas corporais: a) ortostática natural; b) anteriorização da cabeça associada com extensão da coluna … Show more

“…Analysis of the posture in a lateral view in the study were previously performed by Carneiro and Teles 18 to study anteriorization of the head. In a previous study, Pasinato et al 29 evaluated the roll angle of the head of subjects with and without temporomandibular dysfunction and rated an angle that they called vertical, which describes an anteriorization or a posteriorization of the head.…”

“…The angles studied were 18 : • Condyle-acromion angle (ACA): angle formed by the intersection of the line formed by the union of the marked points mandibular condyle and the acromion of the scapula with the line perpendicular to the ground. • Mento-sternal angle (AME): angle formed by the intersection of the line formed by the union of the chin's most anterior point, not marked because of the easy visualization in a lateral view, with the previously marked spot on the xiphoid process with the line perpendicular to the ground.…”

“…In general, the prejudice in vocal production is related to inadequate respiratory function, incorrect use of resonators, hypertension of lingual, glottal and cervical muscles [1][2][3] . The participation of the extrinsic laryngeal muscle on the voice has been the focus of scientific studies and research in recent years, once the dysphonia, especially hyperfunctional, may be related to muscle imbalances craniocervical [2][3][4][5][6][7] . Through of careful assessment, it is possible to determine if the vocal dysfunction alters the behavior of the cervical muscles and to verify the possible influence on body posture and contrariwise.…”
