Exercícios de trato vocal semiocluído: revisão de literatura

Abstract: Este trabalho tem como tema os exercícios de trato vocal semiocluído (ETVSO) e procura sintetizar e organizar, por meio de revisão de literatura, informações sobre noções físicas e de anatomofisiologia subjacentes aos ETVSO e seus diferentes tipos, com descrição, aplicabilidades clínicas, restrições, tempo de realização, efeitos e eficácia. Os ETVSO são realizados com alguma oclusão no trato vocal que modifica a impedância acústica e gera ressonância retroflexa, afastando as pregas vocais na vibração, reduzind… Show more

“…With this finding, it is clear that the technique does not promote hypertension of the vocal apparatus, which is consistent with indications from the literature of improved efficiency and vocal economy, reducing the level of phonation pressure and less effort vocal [1][2][3][5][6][7][8][9] .…”

“…As the patient had already done speech, hearing and language therapy for about one year, without success, the tubes technique as a treatment was chosen, because of the benefits reported in the literature, through SOVTEs 6,7,11 . After M2, the first speech therapy session was performed, through the technique of phonation into a latex tube (35 cm in length, 0.9 cm in diameter and 0.2 cm in thickness), immersed in a 600 ml PET bottle (with 300 ml of water, at room temperature), 15 cm deep.…”

“…The semi-occluded vocal tract exercises (SOVTE) influence the glottic source, through retroflex resonance. It changes the characteristics of vocal folds vibration, through increase of vocal tract impedance in the moment of emission [5][6][7] . A SOVTE, type phonation into resonance tubes of different sizes, has been used in the treatment of different dysphonia diagnoses, either hypo-or hyperfunctional.…”

“…These exercises are designed to promote vocal economy and efficiency generating a phenomenon called retroflex resonance, which favors the coaptation of the vocal folds during vibration (1,7) . The SOVTEs are performed based on vocal tract occlusion (8) . They aim to promote aerodynamic and vocal tract changes (9,10) and increase the filter-source interaction by increasing supraglottic and intraglottic pressure, consequently favoring impedance through adduction of the vocal fold and narrowing of the epilarynx tube, which result in vocal production with less effort and greater efficiency and economy (7,10) .…”
