“…The decrease in the dominant amplitude of the opening variation of LVF in the anterior glottic region in the present study corroborates another one that analyzed DKG parameters in nebulization effects, which observed a smaller VF opening amplitude in women with laryngeal changes 28 . The findings demonstrate that VF, after therapeutic intervention, decreases the magnitude of lateral movement during phonation.…”

“…Combining vocal techniques with TENS to reduce muscle tension restores functionality and muscle mobility in the extrinsic region of the larynx, shoulder girdle, and neck, also with suggested positive results in the vocal rehabilitation of dysphonic individuals [21][22][23][24][25][26] . Although the literature demonstrates positive CVRP 19,20 and TENS [21][22][23][24][25][26] effects in dysphonia rehabilitation, scarce research has used HSV to analyze the effects of therapeutic procedures on glottal function 27,28 . It is important to understand the functional changes in VF vibration as a result of singers' clinical voice rehabilitation so that therapeutic protocols can be defined according to the functional aspects of these professionals' larynx.…”

Purpose: to evaluate the effects of the Comprehensive Vocal Rehabilitation Program associated with the application of transcutaneous electrical nerve stimulation through digital kymography in singers with vocal complaints. Methods: an experimental intrasubject comparative study in 24 singers, who underwent the rehabilitation program associated with transcutaneous electrical nerve stimulation. They were assessed with laryngeal high-speed videoendoscopy before and after vocal rehabilitation. The paired t-test and Wilcoxon test were used to compare the two assessments. The significance level was set at 5%. Results: significant differences were found in the maximum opening, dominant amplitude of the opening variation and dominant frequency of the opening variation of the right vocal fold in the posterior glottic region, and in maximum opening, mean opening, dominant amplitude of the opening variation of the left vocal fold and dominant frequency of the opening variation of both vocal folds in the anterior glottic region. Conclusion: the results showed that the Comprehensive Vocal Rehabilitation Program associated with transcutaneous electrical stimulation decreased the opening amplitude of the vocal fold, increased the vibration frequency, and improved glottal closure in the anterior and posterior glottic regions.

“…Quanto ao presente trabalho, a diminuição da amplitude dominante de variação de abertura da PVE na região anterior da glote corrobora um estudo que analisou os parâmetros da DKG nos efeitos da nebulização, tendo observado menor amplitude na abertura das PPVV em mulheres com alterações laríngeas 28 . Os achados demonstram que as PPVV, após intervenção terapêutica, diminuem a magnitude do movimento lateral durante a fonação.…”

“…A combinação de técnicas vocais com a TENS para redução da tensão muscular, além do restabelecimento da funcionalidade e mobilidade muscular na região extrínseca da laringe, cintura escapular e cervical sugerem resultados positivos na reabilitação vocal de indivíduos disfônicos [21][22][23][24][25][26] . Apesar de a literatura evidenciar os efeitos positivos do PIRV 19,20 e da TENS [21][22][23][24][25][26] na reabilitação das disfonias, pesquisas que analisaram os efeitos de procedimentos terapêuticos na função glótica via HSV são escassas 27,28 . Compreender as modificações funcionais da vibração das PPVV como resultado da reabilitação de cantoras na clínica vocal é importante para que sejam definidos protocolos terapêuticos que considerem os aspectos funcionais da laringe dessas profissionais.…”

RESUMO Objetivo: avaliar os efeitos do Programa Integral de Reabilitação Vocal associado à aplicação da estimulação elétrica nervosa transcutânea por meio da videoquimografia digital em cantoras com queixa vocal. Métodos: estudo experimental comparativo intrassujeitos com 24 cantoras, que realizaram o programa de reabilitação associado à estimulação elétrica nervosa transcutânea. A avaliação, por meio da videolaringoscopia de alta velocidade, foi realizada antes e após a reabilitação vocal. Os testes T pareado e de Wilcoxon foram utilizados para comparação das duas avaliações. Considerou-se o nível de significância de 5%. Resultados: diferenças significantes foram identificadas quanto aos parâmetros de abertura máxima, amplitude dominante de variação de abertura e frequência dominante de abertura da prega vocal direita na região posterior da glote, além dos parâmetros de abertura máxima, abertura média, amplitude dominante de variação de abertura da prega vocal esquerda e frequência dominante de abertura de ambas as pregas vocais na região anterior da glote. Conclusão: os resultados mostraram que o Programa Integral de Reabilitação Vocal associado à estimulação elétrica transcutânea promoveu uma diminuição da amplitude de abertura da prega vocal e aumento da frequência de vibração, além de um melhor fechamento glótico nas regiões anterior e posterior da glote.

Demystifying Vocal Hygiene: Considerations for Professional Voice Users

Purpose of Review Discuss current literature and clinical experience related to vocal hygiene, with special consideration for the professional and performing voice user. Recent Findings Use and non-use-related vocal hygiene factors that may impact professional and performing voice users include hydration, laryngeal irritants, phonotrauma, and voice rest. Key considerations include monitoring both systemic and surface hydration, maintaining awareness of key signs and symptoms of reflux, avoiding phonotraumatic patterns and/or learning to pace voice use when high-impact vocal behaviors are required. Complete voice rest is better suited to treat acute injury and not practical for day-to-day vocal management. Summary Vocal hygiene is one tool within voice therapy that plays a key role in vocal injury prevention and rehabilitation when paired with direct voice therapy. Vocal hygiene education should be individualized, guided by the tenants of meta-therapy and motivational interviewing to increase self-efficacy for change and adherence to recommendations.
