RESUMO
INTRODUCTION: Indirect vocal therapy (IVT) has tools that aim to modify an individual's behavior, emotional factors, and physical environment for restoring vocal quality. Then, vocal health guidance may promote the desire for caring about the voice and prevent or treat behavioral dysphonia. However, studies that used parts of IVT have shown conflicting results. Hence, the main objective of this study was to introduce an IVT program based on the taxonomy of Van Stan et al. [Am J Speech Lang Pathol. 2015;24(2):101-25]. The second objective of this study was to analyze the preliminary effects of the IVT program on vocal comfort through the self-assessment of vocal fatigue, vocal symptoms, vocal handicap, and vocal quality in patients diagnosed with behavioral dysphonia. METHOD: This is an experimental, analytical, and prospective pilot study. Nine participants (five women; four men) aged between 18 and 50 years with behavioral dysphonia participated in this study. They underwent the IVT program with guidance about vocal health, general health, emotional factors, and motivation. The therapy was implemented twice per week, totalizing eight sessions, each lasting 35 min. Participants were assessed before therapy started (M1), after it ended (M2), and 1 month after as a follow-up (M3). As assessment, participants filled in the Vocal Fatigue Index (VFI), Voice Symptoms Scale (VoiSS), and Vocal Handicap Index-30 (VHI-30). Additionally, they had their voices recorded for acoustic measures (i.e., cepstral peak prominence-smoothed, alpha ratio, and L1-L0) and auditory-perceptual analysis using the GRBASI scale. RESULTS: The acoustic measures and auditory-perceptual analysis showed no significant differences between the assessment moments. The auditory-perceptual analysis showed a mild deviation in participants' vocal quality. The participants' scores of the VFI, VoiSS, and VHI were lower in M2 and remained lower in M3. CONCLUSION: The IVT program had positive results in voice-related self-assessment and vocal comfort. However, further studies are necessary to elucidate its effects on the vocal quality of participants with behavioral dysphonia.

Objective: to compare the immediate effects of low-frequency TENS employment on vocal quality in women with behavioral dysphonia before and after vocal exercises.Methodology: 30 women (mean = 31.3 years old), diagnosed with behavioral dysphonia received low-frequency TENS before (TENS + VE Group) and after vocal exercises (VE + TENS Group) with a 1-week washout. They had their sustained vowel/a/and running speech recorded before and after each procedure for auditory-perceptual analysis and acoustic measures. The low-frequency TENS parameters applied were symmetrical biphasic quadratic pulse, 200 µs phase, 10 Hz frequency, intensity on the motor threshold, and the electrodes were positioned on the submandibular and superior fibers of the trapezius muscle region. The vocal exercises: tongue trill, humming, finger kazoo, and water resistance therapy were performed totalizing 20 min.Results: intragroup analysis of sustained vowel/a/showed reduction in both groups of strain parameter and increased the breathiness; only VE + TENS Group increased the instability parameter, decreased fundamental frequency, and increased in SPI values; the running speech analysis showed an increase in the overall degree, roughness, and breathiness parameters. However, in VE + TENS Group, there was a statistically significant decrease in the intensity of the strain and an increase in breathiness. The acoustic measures showed that VE + TENS Group had a higher variation than TENS + VE Group regarding NHR.Conclusion: vocal exercises followed by low-frequency TENS have more immediate positive effects on voice quality than the low-frequency TENS followed by vocal exercises. This is a preliminary immediate effects study, and these effects could be verified through long-term assessments.
RESUMO
OBJECTIVES: To analyze the immediate effects of voiced high-frequency oscillation (VHFO) and Lax Vox technique on vocal quality and self-reported intensity of vocal and laryngeal symptoms in individuals with behavioral dysphonia. METHODS: This experimental, prospective, randomized cross-over study, investigated thirty adults (15 women and 15 men) with behavioral dysphonia (vocal complaints, altered voice on auditory-perceptual evaluation, vocal nodules or mucosal thickening, and incomplete glottic closure). The outcome variables analyzed were auditory-perceptual analysis, acoustic analysis (voice quality characteristics), and self-reported intensities of vocal and laryngeal symptoms. Each participant performed two exercises-VHFO and Lax Vox technique-in a random sequence for 3 minutes. A 7-day washout period was provided between the exercises. The data were analyzed using the paired t-test and Wilcoxon test (P < 0.05). RESULTS: After VHFO, no significant difference was observed on auditory-perceptual evaluation in all participants, whereas the Lax Vox technique worsened breathiness among women (P = 0.027). VHFO significantly increased the fundamental frequency (P = 0.014) and decreased the noise harmonic ratios for women (P = 0.026). Among men, there was a decrease in shimmer parameter (P = 0.035). Moreover, symptoms such as "lump in the throat" (P = 0.005), "voice loss" (P = 0.017), and "high-pitched voice" (P = 0.023) decreased in women after VHFO, whereas in men, "itchiness" and "hoarseness" (P < 0.001) decreased after VHFO. The Lax Vox technique decreased "hoarseness" (P = 0.003) in women, without any effect in men. CONCLUSION: The VHFO exercise provided more positive immediate effects results than the Lax Vox technique regarding vocal quality and self-reported symptom intensity in participants with behavioral dysphonia.

OBJECTIVES: The primary objective was to analyze and compare the effects of the voiced high-frequency oscillation (VHFO) and Lax Vox techniques in different performance times. The secondary objective was to determine if there were any differences between the exercises in men and women. METHODS: Thirty volunteers (15 male, 15 female) without vocal complaints or any history of dysphonia participated in this study. The volunteers performed the VHFO and the Lax Vox techniques with a week washout, and the performance times were 1- and 3-minute long with a 15-minute interval. They answered two questionnaires on vocal and laryngopharyngeal symptoms intensity self-assessment and had acoustic measurements (cepstral peak prominence-smoothed - CPPs - , alpha ratio, and L1-L0) obtained, before 1 minute (M0), after 1 minute (M1), and after 3 minutes (M3). They had their sustained vowel /a/ and number counting 1-10 recorded. Data were analyzed by using the repeated measures ANOVA (P < 0.05) and the post hoc Tukey's test. RESULTS: For vowel /a/, men had higher CPPs and lower alpha ratio values. For number counting, men had lower CPPs values, and for both genders there was an improvement after M1, which remained at M3. For the low-pitched voice symptom, men showed a decrease after M1, regardless of the exercise. Men had better results after VHFO, while women had better results after the Lax Vox technique for the tightness symptom. Regardless of exercise or gender, there was a decrease in tickling and irritated throat after M1, but at M3 their intensity tended to increase. The lump in the throat symptom decreased at M1 and remained at the same intensity at M3 regardless of exercise or gender. CONCLUSIONS: It is important to be aware of the voice effects and the patient reports when requesting 3 minutes of both exercises. Thus, the conclusion is that the best performance time is 1 minute. For most outcomes, there was no difference between exercises and participants' genders. However, for the low-pitched voice symptom, men benefited more from both exercises, and for tightness, men benefited more from VHFO; in contrast, women benefited more from the Lax Vox technique. Therefore, such gender differences should be considered when choosing these exercises.

OBJECTIVE: To verify safety and compare the immediate effects of voiced high-frequency oscillation (VHFO) using two types of breathing devices on self-perception and vocal quality according to performance time in vocally healthy individuals. METHOD: Thirty individuals (15 women and 15 men) without vocal complaints or any history of dysphonia participated. Each participant performed the VHFO technique with the New Shaker and Shaker Plus devices for 3 (T3), 5 (T5), and 7 minutes (T7). All answered a questionnaire that investigated the intensity of laryngopharyngeal and vocal symptoms before and after performing the VHFO with each device and at different times. After VHFO, at each time, the voice was recorded for further analysis of vocal quality. The participants also answered a self-assessment questionnaire about vocal, laryngeal, breathing, and articulatory sensations. RESULTS: T3 showed a decrease in the laryngopharyngeal symptoms "pain when swallowing," "secretion in the throat," and "phlegm" for both genders and both devices. T7 showed an increase in "dry throat" for both genders and both devices. There was an increase in the symptom "fatigue when speaking" in T3 for both genders after VHFO with the New Shaker device. We also observed a decrease in the symptoms "voice failure" and "dry cough" after VHFO with the Shaker Plus for men in T3, and "voice failure" after VHFO with the New Shaker for women in T5. We found a decrease in the acoustic parameter shimmer for women in T5 and the NHR parameter in T7 for both genders, regardless of the breathing device. There were no changes in the auditory-perceptual analysis of the voice and self-assessment of sensations after VHFO with both devices and for both genders. CONCLUSION: VHFO performed with New Shaker and Shaker Plus is safe and can be used in clinical vocal practice in vocally healthy individuals.
RESUMO
The pursuit for quality of life urged a better understanding of aspects involved in ageing to minimize its consequences. Although many studies investigated older adults' voice, aspects affecting this population voice-related quality of life have not yet been explored. Objective To investigate how aerodynamics and vocal aspects are associated with voice-related quality of life in older adults. Methodology fifty-six older adults aged 60 years or above - 39 women and 17 men - were evaluated. The following procedures were performed: application of the Voice-Related Quality of Life (V-RQOL) protocol; vocal assessment, including auditory-perceptual and acoustic analysis, from which we obtained fundamental frequency (F 0 ), standard deviation of fundamental frequency (SDF 0 ), shimmer, amplitude perturbation quotient (APQ), jitter, pitch period perturbation quotient (PPQ), and harmonics to noise ratio (HNR); aerodynamic assessment using a spirometer; and maximum phonation time (MPT) for /a/, /s/, /z/ and number counting. Results older adults tend to present high V-RQOL scores. Among women, roughness, APQ, and HNR parameters were negatively correlated with V-RQOL, whereas F 0 was positively. We found no correlation between spirometry measurements and V-RQOL. MPT for /a/, /z/, and number counting was positively correlated with V-RQOL solely among men. Conclusion Vocal roughness and acoustic parameters have a negative impact on the quality of life of older women. Respiratory aspects related to the available air support for speaking affected the most the voice-related quality of life of older men.

PURPOSE: To verify and compare the immediate effects of the voiced oral high-frequency oscillation (VOHFO) technique and the phonation into a silicone resonance tube in the elderly self-perception of vocal and laryngeal symptoms and in their voice quality. METHODS: 14 elderly women, over 60 years old, performed the VOHFO and phonation into a resonance tube technique (35cm in length and 9mm in diameter) with one-week interval between both to avoid carry-over effect. Initially, all participants answered questions regarding the frequency and intensity of their vocal/laryngeal symptoms. Recordings of the sustained vowel /a/ and counting numbers were performed for posterior perceptual and acoustic analyses of the voice quality. The maximum phonation time (MPT) for /a/, /s/, /z/ and counting numbers were also obtained. After that, a draw lot established which technique (VOHFO or resonance tube) would be initially applied for three minutes. After the exercise performance the same procedures were carried out and the elderly women answered a self-assessment questionnaire about the effect of the techniques in her voice, larynx, breathing and articulation. Comparison pre and post each technique were analyzed using ANOVA, Wilcoxon and Mann-Whitney tests. The sensations after the techniques were assessed using the Chi-square test (p<0.05). RESULTS: The comparison of both techniques showed decrease in roughness and improvement in resonance for counting numbers after the resonance tube and same outcomes post VOHFO. There were no significant differences for the other analyzed variables between groups. CONCLUSION: The phonation into a resonance tube exercise improves the vocal quality of elderly women. In addition, both exercises are similar regarding self-perception of vocal / laryngeal symptoms and sensations post three minutes of the technique, suggesting that VOHFO can be safely applied in voice therapy for this population.
OBJETIVO: Verificar e comparar os efeitos imediatos da técnica de oscilação oral de alta frequência sonorizada (OOAFS) e sopro sonorizado com tubo de ressonância na autopercepção de sintomas vocais/laríngeos e na qualidade vocal de idosas. MÉTODO: Participaram 14 mulheres idosas que realizaram as técnicas OOAFS e sopro sonorizado com tubo de ressonância de silicone, com wash-out de uma semana. Todas responderam questões sobre frequência e intensidade dos sintomas vocais/laríngeos; foram submetidas à gravação da vogal sustentada /a/ e contagem de números, para análise perceptivo-auditiva e acústica vocal. Foram extraídos os tempos máximos de fonação (TMF). Em seguida, sorteou-se a técnica a ser realizada: OOAFS ou tubo de ressonância, por três minutos em tom habitual. Após exercício, os mesmos procedimentos da avaliação inicial foram repetidos e as idosas responderam a um questionário de autoavaliação sobre os efeitos das técnicas. Os dados foram comparados antes e após aplicação das técnicas por meio dos testes ANOVA, Wilcoxon e Mann-Whitney; para as sensações vocais após técnicas, aplicou-se teste Quiquadrado(p<0,05). RESULTADOS: Ao comparar as técnicas, verificou-se diminuição da rugosidade e melhora da ressonância na contagem dos números após tubo de ressonância e manutenção dos resultados após OOAFS. Não houve mais diferenças significantes para as demais variáveis estudadas entre os grupos. CONCLUSÃO: O sopro sonorizado com tubo de ressonância melhora a qualidade vocal de mulheres idosas. Além disso, ambos os exercícios apresentaram semelhanças na autopercepção dos sintomas vocais/laríngeos e sensações, sugerindo que a OOAFS é segura e pode ser empregada na terapia de voz nesta população.

RESUMO O objetivo deste relato de caso foi descrever os resultados da terapia fonoaudiológica intensiva, em um caso de presbifonia, e apresentar uma proposta de tratamento vocal para idosos, demonstrando seus resultados na qualidade vocal, qualidade de vida e imagem laríngea de um paciente com presbifonia. O programa Terapia Vocal para Idosos (TVI) é constituído por uma sequência de exercícios, que visam ao aumento da loudness, coordenação pneumofonoarticulatória, melhora na vibração de mucosa e equilíbrio de ressonância, além da variação e controle da frequência. O modelo terapêutico em questão foi aplicado em um indivíduo do gênero feminino, com 87 anos de idade e queixas de voz fraca e dificuldade em ser ouvido. As terapias ocorreram de maneira intensiva em 16 sessões com 30 minutos de duração, quatro vezes por semana e com realização de exercícios em casa. A experiência de aplicação do programa em formato intensivo mostrou efeitos positivos na qualidade vocal, com diminuição do desvio global da voz, soprosidade na emissão sustentada e rugosidade na emissão sustentada e fala. A melhora no desempenho vocal refletiu em aumento nos valores dos domínios físico e global do protocolo de qualidade de vida relacionada à voz. Houve, também, melhora no fechamento glótico. O tratamento vocal com o método TVI intensivo demonstra efeitos positivos no tratamento da presbifonia e tem o potencial de promover benefícios na qualidade vocal, na qualidade de vida relacionada à voz e nos aspectos laríngeos dos idosos.
ABSTRACT The aim of this study is to describe the results of intensive voice therapy in a presbyphonia case and to propose a voice treatment program for the elderly by demonstrating vocal quality, quality of life and laryngeal image results. The Voice Therapy for the Elderly (VTE) program consisted of a sequence of exercises that aimed at increasing intensity, pneumo-articulatory coordination, mucosal vibration and resonance balance, and increasing frequency variation and control. The therapeutic model in question was applied to an 87-year-old female subject with complaints of a weak voice and difficulty to be heard by others. This therapy program was applied with an intensive approach over 16 sessions, 30 minutes each session, four times a week, with assigned homework. The intensive voice therapy format demonstrated positive effects on vocal quality with an overall reduction in voice deviation, breathiness, and roughness on sustained phonation and speech. Vocal performance improvement showed a subsequent increase in the physical and general aspects of voice-related quality of life. There was also improvement in glottic closure. Voice treatment via the VTE method, with an intensive approach revealed to be positive in the treatment of presbyphonia and can potentially promote benefits for the elderly in terms of voice quality, voice-related quality of life, and laryngeal changes.

OBJECTIVES: To investigate musculoskeletal pain, vocal fatigue, and voice-related quality of life of tele-operators and compare these aspects with nonvoice-related professionals; and verify if there is a relationship between musculoskeletal pain and vocal fatigue and voice-related quality of life (V-RQOL) of tele-operators and nonvoice-related professionals. METHODS: Thirty-five tele-operators (SG) and 35 nonvoice-related professionals with no vocal complaints (control group) participated in the study. All of them answered investigating questionnaires of musculoskeletal pain, vocal fatigue index, and V-RQOL. The data were statistically analyzed in aim to compare the groups and the association between variables. RESULTS: Women from SG presented higher pain frequency in their upper back than women from control group (Pâ¯=â¯0.039). Different correlations were observed between musculoskeletal pain and vocal fatigue, just as between musculoskeletal pain and V-RQOLindex, for men and women in both groups. However, men presented a higher number or correlations between the protocols than women from both groups. CONCLUSION: Female tele-operators presented higher pain frequency on their upper back when compared to nonvoice-related professional women. Musculoskeletal pain has a negative impact on voice-related quality of life and on the increase of vocal fatigue during oral communication, regardless of the professional use of the voice.

OBJECTIVE: This study aims to propose and analyze the effect of a voice therapy program (VTP) in women with behavioral dysphonia. MATERIALS AND METHODS: This is a controlled, blinded, and nonrandomized cohort study. Participants of this study were 22 women with behavioral dysphonia divided into two groups: G1, 11 women with behavioral dysphonia who received the VTP, and G2, 11 women with behavioral dysphonia who did not receive any intervention. Before and after 6 weeks, the outcome variables evaluated in both groups were auditory-perceptual evaluation of the global degree of vocal quality (vowel /a/ and counting), instrumental acoustic parameters, Voice-Related Quality of Life, vocal and larynx symptoms, and musculoskeletal pain. The statistical analysis used the Wilcoxon, chi-square, and Mann-Whitney tests (P < 0.05). RESULTS: After 6 weeks, we observed a significantly higher improvement in the general degree of vocal deviation in vowels, a reduced F0 and symptom of "fatigue while talking" in G1, and an increased "shoulder" pain intensity in G2. Both groups showed improvement in the socioemotional domain of Voice-Related Quality of Life. In addition, the comparison between the groups showed a significantly greater reduction in fundamental frequency and the "voice loss" symptom in G1 compared with G2. CONCLUSIONS: The VTP using semioccluded vocal tract exercises obtained a positive effect on voice quality, symptoms, and musculoskeletal pain in women with behavioral dysphonia. The proposal, based on the taxonomy of voice therapy, seems to have promoted a phonatory balance, muscle relaxation, and improvement in the vocal resistance of this population.
