“…In the authors' experience, abnormal body posture is frequently observed in patients with voice problems. This is in accordance with the fi ndings of other authors [7][8][9] . Correction of body posture and muscular hypertonicity frequently forms a part of voice therapy, particularly in the European countries [20] .…”

“…The position of the larynx, assumed to be important for phonation, can be affected by the inhalatory behaviour of the speaker [6] . Schneider et al [7] also consider that muscular hypertonicity and body posture can infl uence voice production. In the authors' experience, abnormal body posture is frequently observed in patients with voice problems.…”

The aim of this study was to investigate the relationship between extrinsic laryngeal muscular hypertonicity and deviant body posture on the one hand and voice handicap and voice quality on the other hand in teachers with persistent voice complaints and a history of voice-related absenteeism. The study group consisted of 25 female teachers. A voice therapist assessed extrinsic laryngeal muscular tension and a physical therapist assessed body posture. The assessed parameters were clustered in categories. The parameters in the different categories represent the same function. Further a tension/posture index was created, which is the summation of the different parameters. The different parameters and the index were related to the Voice Handicap Index (VHI) and the Dysphonia Severity Index (DSI). The scores of the VHI and the individual parameters differ significantly except for the posterior weight bearing and tension of the sternocleidomastoid muscle. There was also a significant difference between the individual parameters and the DSI, except for tension of the cricothyroid muscle and posterior weight bearing. The score of the tension/posture index correlates significantly with both the VHI and the DSI. In a linear regression analysis, the combination of hypertonicity of the sternocleidomastoid, the geniohyoid muscles and posterior weight bearing is the most important predictor for a high voice handicap. The combination of hypertonicity of the geniohyoid muscle, posterior weight bearing, high position of the hyoid bone, hypertonicity of the cricothyroid muscle and anteroposition of the head is the most important predictor for a low DSI score. The results of this study show the higher the score of the index, the higher the score of the voice handicap and the worse the voice quality is. Moreover, the results are indicative for the importance of assessment of muscular tension and body posture in the diagnosis of voice disorders.

“…In the present study, a vocal rest of 30 seconds between each set was used, which may have contributed to the better results of auditory perceptual analysis presented by the participants. The vocal rest may also have provided a recovery of larynx intrinsic muscles, in function of the suppression of muscle activity which constitutes passive rest (9). The execution time of STVT on the present study was variable, being conducted according to the maximum phonatory duration of each participant.…”

“…Authors (9) indicate that the application of vocal exercise for ten minutes, three times daily is ideal for a good muscle conditioning. In the present study, the participant who presented medial vestibule constriction conducted the STVT during 7.52 minutes (the longest duration), approaching the conditioning time proposed by previously cited authors.…”

TEMA: a eficácia da técnica de vibração sonorizada de língua (TVSL). OBJETIVO: investigar o impacto vocal e laríngeo e as sensações surgidas frente à execução da técnica de vibração sonorizada de língua. MÉTODO: a TVSL foi aplicada em três séries de quinze repetições, em tempo máximo de fonação com tom e intensidade habituais, com intervalos de 30 segundos de repouso passivo entre cada série. Participaram do estudo 24 sujeitos, do sexo feminino, com idades entre 20 e 30 anos, sem queixas vocais. Todos esses indivíduos foram submetidos à avaliação da laringe, por meio do exame de videolaringoestroboscopia, análise perceptivo-auditiva e acústica da voz, por meio dos programas Multi-Dimensional Voice Programa (MDVP), Model 5105 e Real Time Spectrogram, da Key Elemetrics, antes e após a execução da TVSL. RESULTADOS: após a execução da TVSL evidenciou-se diferença estatisticamente significativa para: a melhora do tipo de voz; do foco de ressonância vertical; da qualidade vocal; o predomínio de sensações positivas; a manutenção dos parâmetros das imagens laríngeas (fechamento glótico, constrição do vestíbulo laríngeo, amplitude e simetria de vibração das pregas vocais); o aumento da freqüência fundamental; a melhora de parâmetros da avaliação espectrográfica, em filtros de Banda Larga e Banda Estreita e a melhora da constrição medial do vestíbulo, conforme o aumento do tempo de execução da TVSL. CONCLUSÃO: a TVSL apresenta modificações sobre a fonte glótica e sobre o filtro ressonantal.

“…Furthermore, Elliot et al [40] and Laukkanen et al [41] documented that vocal economy was improved by decreasing muscular activity in the laryngeal muscles and lowering laryngeal position in vowel production after vocal training. Schneider et al [42] suggested that constant overload training on respiratory and laryngeal muscles can change control mechanisms by enhancing muscular fitness resulting in better vocal function.…”

The influence of frequency and intensity in Min dialect on maximum vocal performance has not been investigated. The purposes of this study are (1) to investigate the physiological frequency and intensity ranges of the tonal dialect of Min, and (2) to compare the physiological frequency and intensity ranges of Min to those of nontonal languages. The subjects were 40 normal Taiwanese adults. All subjects were native Min speakers. The lowest frequency, the highest frequency, the maximum range of vowel frequency change (MRVFC), soft voice, loud voice, and the dynamic intensity range were obtained from voice range profiles. The independent t test was used to find the statistical significance of all frequency and intensity variables between female and male speakers in vocal range profiles. The results revealed that female speakers had significantly greater lowest frequency and highest frequency than male speakers. Male speakers had a significantly greater MRVFC than female speakers. Moreover, Min speakers had a greater MRVFC and dynamic intensity range than most of nontonal language speakers. The data provide an assessment tool of vocal function for Min speakers.
