The Efficacy of the Manual Circumlaryngeal Therapy for Muscle Tension Dysphonia: A Systematic Review and Meta-analysis.

OBJECTIVE: Muscle tension dysphonia (MTD) is the most common functional voice disorder. Behavioral voice therapy is the front-line treatment for MTD, and laryngeal manual therapy may be a part of this treatment. The objective of this study was to investigate the effect of manual circumlaryngeal therapy (MCT) on acoustic markers of voice quality (jitter, shimmer, and harmonics-to-noise ratio) and vocal function (fundamental frequency) through a systematic review with meta-analysis. DATA SOURCES: Four databases were searched from inception to December 2022, and a manual search was performed. REVIEW METHODS: The PRISMA extension statement for reporting systematic reviews incorporating a meta-analysis of health care interventions was applied, and a random effects model was used for the meta-analyses. RESULTS: We identified 6 eligible studies from 30 studies (without duplicates). The MCT approach was highly effective on acoustics with large effect sizes (Cohen's d > 0.8). Significant improvements were obtained in jitter in percent (mean difference of -.58; 95% CI -1.00 to 0.16), shimmer in percent (mean difference of -5.66; 95% CI -8.16 to 3.17), and harmonics-to-noise ratio in dB (mean difference of 4.65; 95% CI 1.90-7.41), with the latter two measurements continuing to be significantly improved by MCT when measurement variability is considered. CONCLUSION: The efficacy of MCT for MTD was confirmed in most clinical studies by assessing jitter, shimmer, and harmonics-to-noise ratio related to voice quality. The effects of MCT on the fundamental frequency changes could not be verified. Further contributions of high-quality randomized control trials are needed to support evidence-based practice in laryngology. Laryngoscope, 134:18-26, 2024.

The effects of transcutaneous electrical nerve stimulation on muscle activity pattern in professional voice users with muscle tension dysphonia using surface electromyography data: A pilot study.

OBJECTIVES: Muscle Tension Dysphonia is a voice disorder, which results in stiffness in the laryngeal extrinsic muscles, intense collision, painful contractions, and vibrations of the vocal cords. Due to the multifactorial identity of Muscle Tension Dysphonia, its therapeutic approach must be multidisciplinary. METHODS: The participants were divided into two groups: a control group (5participants) that received Circumlaryngeal Manual Therapy (CMT) + Placebo Transcutaneous Electrical Nerve Stimulation and an experimental group (5participants) that received Transcutaneous Electrical Nerve Stimulation + CMT. Both groups received 10 sessions of treatment, twice a week, for 40 min each. Before and after treatment, participants were assessed using the Dysphonia Severity Index (DSI) and surface electromyography for their ability to sustain the vowels /e& u/and count from 20 to30. RESULT: After therapy, there were substantial improvements in the DSI (2.72 ± 0.55, P < 0.05) and muscle electrical activity in the control group. The DSI (3.66 ± 0.63, P < 0.05) and muscle electrical activity were also significantly improved in the experimental group after treatment. The findings of the between-group comparison after treatment revealed a significantly greater increase in the Dysphonia Severity Index in the experimental group compared with the control group (P = 0.037). Although there was no significant difference between the two groups in terms of muscle electrical activity, clinically significant changes were more noticeable in the experimental group when compared with the control group. CONCLUSIONS: Positive results were seen in both groups. The results demonstrate that both approaches relax vocal tract muscles. As a result, Transcutaneous Electrical Nerve Stimulation was recommended as a complementary treatment for clients with Muscle Tension Dysphonia.

Fusion of Emotional Thinking and Mental Health of Students in Vocal Music Teaching.

Vocal psychology belongs to the branch of music psychology, which is the cross-study of vocal art and psychology, and is also a new discipline with both theory and application. Vocal singing uses a thinking, conscious person as an instrument that is necessarily governed by the psyche over the physiology, relying on the brain to direct the movement of the singing muscles and the coordination of the vocal organs. The purpose of this thesis is to explore the application of vocal psychology in vocal singing and teaching, to explain the generation and development of various psychological phenomena in singing activities, to reveal the role and significance of various psychological factors, to provide singers with a theoretical basis for psychological aspects, and to correctly understand the scientific laws of the inner psychology of vocal singing. The effectiveness of classroom teaching is reflected in effective and efficient aspects. The effectiveness of a vocal lesson can be measured by the criteria of whether the teaching is oriented, scientific, artistic, and efficient. Effective teaching design is the basis of teaching effectiveness, elaborate teaching organization is the guarantee of teaching effectiveness, and flexible teaching methods are the root of teaching effectiveness; all three need to be closely combined and organically unified. Effective teaching design is a holistic thinking before the implementation of teaching; all factors related to teaching, practice, and evaluation should be fully considered in the teaching design; teachers should take the learning effect of students and the cultivation of employability as the starting point for effective teaching design; and the classroom teaching of "vocal music" is a "process" and teachers should teach in accordance with the teaching design. They should focus on guiding students to experience and cultivate their abilities in a series of "processes" such as the emotion of vocal music, the teaching situation, the effect of listening, the creation of expression, and the aesthetic value. In addition, teachers should combine the teaching methods of transmission and inspiration, classroom teaching, and after-school training and combine relatively fixed teaching methods with flexible teaching methods to maximize the effectiveness of teaching.

Effect of Pompage on Vocal and Respiratory Measurements from Female Teachers: A Randomized Clinical Trial.

INTRODUCTION: Teachers stand out among occupational groups due to their contribution to modern societies, and their voice is the main form of interaction. OBJECTIVE: The aim of the study was to verify the changes in vocal and respiratory measurements from teachers with vocal and musculoskeletal complaints and with normal larynx after applying a musculoskeletal manipulation protocol of myofascial release using pompage. METHODS: Controlled and randomized clinical trial with 56 participants: 28 teachers in the study group and 28 teachers in the control group. Anamnesis, videolaryngoscopy, hearing screening, sound pressure and maximum phonation time measurements, and manovacuometry were performed. The musculoskeletal manipulation protocol of myofascial release using pompage consisted of a total of 24 sessions, 40 min for each session, three times a week, for 8 weeks. RESULTS: There was a significant improvement in the maximum respiratory pressure in the study group after the intervention. The sound pressure level and the maximum phonation time did not change significantly. DISCUSSION AND CONCLUSION: Musculoskeletal manipulation protocol of myofascial release using pompage had a direct effect on the respiratory measurements from female teachers, significantly increasing the maximum respiratory pressure but without affecting sound pressure level and the /a/ maximum phonation time.

Voice-Related Problems, Vocal and Non-Vocal Habits in Naradiya Kirtankars: A Preliminary Study.

OBJECTIVE: Naradiya kirtan is a part of India's rich folk heritage. Voice demands of the kirtankar (kirtan performer) include a combination of recitation, narration, and singing. Slight to moderate deviations in their voice could hamper their public image as well as endanger their career. A preliminary study was undertaken to explore the voice problems, vocal and non-vocal habits of Naradiya kirtankars. STUDY DESIGN: Cross-sectional study design. METHOD: A 22-item questionnaire was developed in English language and translated to Marathi language. This questionnaire was administered on 40 Naradiya kirtankars through purposive sampling. Participants included Naradiya kirtankars located in Mumbai and Pune cities with minimum of one-year training in the field and proficiency in Marathi language. RESULTS: Statistical analysis revealed that kirtankars might be at a risk of developing voice problems. Among the kirtankars with voice problems, frequently pursued primary occupations involving extensive voice use, performed in a noisy environment, indulged in excessive talking, strained the neck muscles while voicing, impersonated voice, had reduced duration of sleep, and hearing difficulty as compared to kirtankars without voice problems. CONCLUSION: Study findings highlight the need for dedicated efforts towards increasing the awareness among the kirtankars' about the vocal, non-vocal factors associated with voice problems and the role of voice health-care professionals in voice care.

Effect of Combined Respiratory Muscle Training (cRMT) on Dysphonia following Single CVA: A Retrospective Pilot Study.

BACKGROUND: Although dysphonia is less prevalent than dysphagia following cerebrovascular accidents, dysphonia does contribute to the burden of disease resulting from stroke. Strengthening muscles of the larynx and respiratory tract through respiratory muscle training (RMT) has proven effective in improving voice after neurological insult. However, approaches to strengthen only the expiratory muscle groups (EMST) dominate the clinical study literature, with variable outcomes. By focusing on exhalation, the contribution of inspiratory muscles to phonation may have been overlooked. This study investigated the effect of combined respiratory muscle training (cRMT) to improve voice function in stroke patients. METHODS: Recorded data of twenty patients with dysphonia following stroke were allocated to an intervention (IG) or a control group (CG) based upon whether they chose cRMT or not while awaiting pro bono voice therapy services. The intervention group (n = 10) was treated daily with three 5-minute sessions of combined resistive respiratory muscle training for 28 days, while the control group (n = 10) received no cRMT or other exercise intervention. Perceptual and acoustic measurements as well as a pulmonary function test were assessed pre-and post-intervention. RESULTS: The intervention group demonstrated significant improvements after 28 days of cRMT in peak flow (127%), patient self-perception of voice improvement (84.41%), as well as in all categories of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V): overall severity (63.22%), roughness (54.76%), breathiness (61.06%), strain (63.43%), pitch range (48.11%) and loudness (57.51%), compared to the control group who did not receive treatment. Furthermore, cRMT also led to significant improvements in maximum phonation time (212.5%), acoustic parameters of vocal intensity, and total semitone range (165.45%). CONCLUSIONS: This pilot study shows promise of the feasibility and effectiveness of cRMT to lessen the signs and symptoms of dysphonia while simultaneously improving breath support.

Myofascial Release Effects in Teachers' Posture, Muscle Tension and Voice Quality: A Randomized Controlled Trial.

OBJECTIVE: Myofascial release (MFR) comprises a set of manual therapeutic techniques applied to many conditions, but specific evidence concerning its effects on body posture, muscle tension and voice has been lacking. Thus, the aim of this study was to verify the effects of MFR in teachers' posture, muscular tension and voice quality. STUDY DESIGN: Randomized controlled trial - crossover. METHODS: Twenty-four teachers, after completing a Sociodemographic and Clinical Questionnaire and providing written informed consent, were randomly distributed into two groups designated Group 1 (G1; n = 12; received MFR first) and Group 2 (G2; n = 12; belong to control group first). All participants received treatment and were into control group, since, after a 14 day period, procedures were switched between groups. Photogrammetry, muscle tension assessed through palpation, algometry, aerodynamic assessment of voice, acoustic and auditory-perceptual analysis of voice were performed before and after interventions. RESULTS: Regarding voice, statistically significant differences were found when intervention was applied to both groups for maximum phonation time (MPT) (G1 P = 0.019; G2 P = 0.004). The acoustic variables did not differ. Concerning the auditory-perceptual analysis of voice statistically significant differences were found when intervention was applied in both groups for Grade in G2 (P = 0.046) and for Roughness in G1 (P = 0.025). Regarding the photogrammetry assessment statistically significant differences were found when intervention was applied to both groups in many parameters while as control group they did not. Concerning the algometry and muscle tension assessed through palpation statistically significant differences were found when intervention was applied in all muscles. CONCLUSIONS: Findings indicated that MFR seems to be an effective therapy in improving MPT, two subscales (Grade and Roughness) of the GRABASH scale, muscle tension assessed through palpation and algometry. Regarding photogrammetry, MFR had an immediately effect in improvement of the posture, especially related with head.

Effect of Pompage on Teachers Self-Assessment-Clinical Trial.

OBJECTIVE: To verify the results of self-assessments of teachers with vocal and musculoskeletal complaints and with the normal larynx, after myofascial release using pompage. METHODS: Double-blind, controlled, and randomized clinical trial including 28 teachers in the study group and 28 teachers in the control group, totaling 56 participants. Anamnesis, video laryngoscopy, hearing screening, clinical and photogrammetric postural assessment, pain threshold in cervical muscles, sound pressure and maximum phonation time measurements, and manovacuometry were performed. Protocols for vocal self-assessment, neck pain, anxiety and depression, and musculoskeletal pain were filled out. Pompage therapy consisted of a total of 24 sessions (8 weeks) of 40 minutes each, three times a week. Afterward, the groups were reassessed. RESULTS: In the study group, there was a significant improvement in the results of the following instruments: Hospital Anxiety and Depression Scale, Vocal Tract Discomfort Scale, Voice Symptoms Scale, Vocal Activity and Participation Profile, Vocal Handicap Index, Voice-Related Quality of Life, and Nordic Musculoskeletal Questionnaire. CONCLUSIONS: After myofascial release using pompage in teachers, there was an improvement in the self-assessed aspects regarding characteristics and quality of life related to the voice, social participation related to the voice, anxiety and depression, and musculoskeletal symptoms.

Pediatric speech-language pathology in East Africa: educational opportunities and availability of speech-language services.

OBJECTIVE: This paper describes the current situation of the provision of speech-language services in East Africa. An overview of the educational opportunities, workforce density, communication rehabilitation planning, caseload, and ethical and/or cultural challenges is provided. METHOD: A narrative review was performed. All papers referring to communication disorders in East African countries were identified from EMBASE, PubMed, ISI Web of Science: Science Citation Index Expanded, and ISI Web of Science: Conference Proceedings Citation Index-Science using the following search terms: speech therapy, speech pathology, speech-language pathology, speech-language rehabilitation, speech-language therapy, logopedics, East Africa, communication disorders, communication difficulties. Two concepts were combined with a Boolean operator 'AND'. RESULTS: At present, there is an alarming shortage of speech-language pathologists in East Africa. This issue is mainly related to the limited availability of educational programs in speech-language pathology. Although more and more universities are beginning to offer such educational programs, the number of available speech-language pathologists is still too low to meet the needs of all children with communication disorders. In addition, speech-language pathologists are often faced with different cultural and ethical obstacles when they provide intervention to East African children with communication disorders. These speech-language pathologists are therefore challenged to take a broader view of their role as a therapist. These alternative roles often include training of other individuals in the context of community-based rehabilitation. CONCLUSION: In the future, it will be important to carefully consider the development of sustainable learning opportunities in East African contexts. Initiatives, for example, "train-the-trainer" workshops, are needed to support the speechlanguage pathologists. Existing models like the communication disability model can aid to create holistic frameworks for the development of sustainable speech-language services in the East African countries.

Association of Genre of Singing and Phonotraumatic Vocal Fold Lesions in Singers.

OBJECTIVES/HYPOTHESIS: To determine if (1) the likelihood of presenting with phonotraumatic lesions differs by singing genre in treatment-seeking singers and (2) if the distribution of phonotraumatic lesion types differs by singing genre. STUDY TYPE: Retrospective. METHODS: Records of singers who presented with a voice complaint over the course of 2.5 years (June 2017-December 2019) were reviewed to determine the proportion of those with phonotraumatic lesions as a function of genre (Study 1). Separately, the lesion types and genres of singers diagnosed with phonotraumatic lesions over a 9-year period (July 2011-March 2020) were determined (Study 2). RESULTS: In Study 1, 191 of 712 (26.8%) dysphonic singers were diagnosed with phonotraumatic lesions. Country/folk, gospel/jazz, and musical theater singers were more likely to present with phonotraumatic lesions. In Study 2, in 443 singers with phonotraumatic lesions, polyps and pseudocysts, but not nodules, were found to be distributed unequally across genres (χ2 p = 0.006, p < 0.0001, p = 0.064, respectively). Praise/worship singers had significantly higher proportions of polyps compared to choral singers (OR 4.8 [95% CI 1.9-12.5]) or compared to musical theater singers (OR 7.2 [95% CI 2.5-20.8]). Opera singers had significantly higher proportions of pseudocysts than choral singers (OR 3.1 [95% CI 1.5-6.1]) or musical theater singers (OR 3.7 [95% CI 1.8-7.6]). CONCLUSIONS: The higher incidence of polyps in praise/worship singers likely reflects the more emphatic nature of singing and the tendency for acute injury. The higher incidence of pseudocysts in opera singers may reflect a more chronic nature of injury. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:1683-1689, 2023.

Reducing the GAP between science and clinic: lessons from academia and professional practice - part A: perceptual-auditory judgment of vocal quality, acoustic vocal signal analysis and voice self-assessment. / Reduzindo o GAP entre a ciência e a clínica: lições da academia e da prática profissional ­ parte A: julgamento perceptivo-auditivo da qualidade vocal, análise acústica do sinal vocal e autoavaliação em voz.

During the XXVIII Brazilian Congress of SBFa, 24 specialists met and, from a leading position on scientific research as a tool for connecting laboratory and clinic, five fronts of knowledge of the voice specialty were discussed as following: Perceptual-auditory judgment of vocal quality; 2. Acoustic analysis of the vocal signal; 3. Voice self-assessment; 4. Traditional techniques of therapy; 5. Modern techniques of electrostimulation and photobiomodulation (PBMT) in voice. Part "a" of this publication was associated with the consolidation of the analyses of the first three aspects. The trend in the perceptual-auditory judgment of vocal quality was related to the use of standard protocols. The acoustic evaluation of the vocal signal is accessible and can be done descriptively or by extraction of parameters, thus preferring multiparametric measures. Finally, the analysis of the individual himself closes this triad of voice documentation, which will be the basis for the conclusion of the evaluation, reference for monitoring progress, and evaluation of treatment results.

No XXVIII Congresso Brasileiro da SBFa, 24 especialistas reuniram-se e, a partir de um posicionamento condutor sobre pesquisa científica como ferramenta de conexão entre laboratório e clínica, cinco frentes de conhecimento da especialidade de voz foram discutidas: 1. Julgamento perceptivo-auditivo da qualidade vocal; 2. Análise acústica do sinal vocal; 3. Autoavaliação em voz; 4. Técnicas tradicionais de terapia; 5. Técnicas modernas de eletroestimulação e fotobiomodulação em voz. A parte "a" desta publicação é a consolidação das análises dos três primeiros aspectos. A tendência no julgamento perceptivo-auditivo da qualidade vocal é o uso de protocolos padrão. A avaliação acústica do sinal vocal é acessível e pode ser feita de modo descritivo ou por extração de parâmetros, preferindo-se medidas multiparamétricas. Finalmente, a análise do próprio indivíduo fecha essa tríade de documentação fonoaudiológica, que será base para a conclusão da avaliação, referência para monitoramento do progresso e avaliação de resultado de tratamento.

The Effect of Platelet-Rich Plasma Injection on Short Term Vocal Outcomes Following Phonosurgery-A Pilot Study.

Background and Objectives: The efficiency and optimal voice rest period following phonosurgery remains debatable. Platelet-rich plasma (PRP) is a safe and cheap alternative to many bioactive agents being studied on animal models, and is already in use in many medical areas. We investigate the short-term effects of PRP and voice rest on voice outcomes following phonosurgery as an alternative to voice rest alone. Materials and Methods: A prospective single-blinded pilot study was conducted. Sixteen patients with a diagnosis of vocal fold cyst and polyps were included, forming equal groups (PRP and voice rest vs. voice rest alone). Voice analysis was carried out on the preoperative day, day three, and week three following surgery. The measured parameters were fundamental frequency (F0), noise-signal ratio (NSR), harmonic poverty (HP), attack alteration (AL), pitch instability (PI), and amplitude instability (AI).VHI(Voice Handicap Index)-30 questionnaires were carried out before surgery and three weeks following surgery to assess the impact of subjective voice change on quality of life. PRP was obtained using commercial kits with separator gel. Results: An average 3.68-fold increase in platelets was obtained with PRP. No side effects were noted after injection. All voice parameters improved on day three and week three following surgery. Statistical significance was noted only in the fundamental frequency of male patients (p = 0.048) in favor of the PRP-voice rest group. In addition, the VHI- 30 questionnaire results between preoperative and postoperative assessments showed statistically significant differences in total VHI score (p = 0.02) as well as the physical (p = 0.05) and emotional (p = 0.02) scale in favor of the PRP-voice rest group. Conclusions: PRP presents short term safety in patients who undergo phonosurgery, although long-term outcomes are unknown. PRP and voice rest are superior to voice rest alone when considering subjective assessment of the voice. When analyzing acoustic parameters, PRP and voice rest are not superior to voice rest alone.

A principal forma de transmitir a tradição oral é através dos cantos nos rituais dos Praiás. Objetivo: resgatar o uso de voz pelos cantadores Pankararu no ritual dos Praiás, à luz do saber tradicional e científico. Método: estudo qualitativo, do tipo história de vida, autobiográfica, no qual foram acessadas memórias individuais e coletivas da comunidade Pankararu, considerando a caracterização do povo, do ambiente e o uso de voz nos rituais. Resultados: os cantadores utilizam a voz de maneira intensa e contínua, sem hidratação, e fumam cachimbo durante o ritual. O local onde cantam é um terreiro, espaço aberto, exposto às intempéries da natureza, com presença de poeira. Para cuidar da voz, baseiam-se no saber tradicional, apresentando uma visão distinta do conhecimento científico, no qual a voz representa sua cultura e identidade. Nesta perspectiva, hábitos descritos pela literatura como deletérios, são considerados saudáveis, demonstrando uma concepção singular de saúde. Conclusão: o conhecimento científico, paralelamente ao tradicional, poderá contribuir para estabelecimento de cuidados que visem à saúde vocal dos Pankararus.  Poderei oferecer ao meu povo, o qual apresenta demandas de saúde, conhecimentos científicos proporcionando uma melhor qualidade de voz e vida.

Introduction: The voice is essential for the preservation and maintenance of the culture of social groups. The Pankararu people link their mother language to religious rituals. The main way of transmitting the oral tradition is through singing in the rituals of Praiás. Objective: To rescue the use of voice by Pankararu singers in the Praiás ritual, considering the traditional and scientific knowledges. Method: Qualitative study, history life, autobiography design, which individual and collective memories of the Pankararu community were accessed, considering the characterization of the people, environment, and voice use in the rituals. Results: The singers use their voices intensely and continuously, without hydration, and smoking pipes during the ritual. The "terreiro" is the place where they sing, an open space, exposed to wuthering and dust. They are based on traditional knowledge for taking care of their voices, in a different view of scientific knowledge, in which voice represents their culture and identity. In this perspective, habits described in the literature as harmful are considered healthy, demonstrating a unique conception of health. Conclusion: Scientific knowledge, in parallel with the traditional one, can contribute to establish care aimed at the vocal health of the Pankararus. I will be able to offer to my people, who have health demands, scientific knowledge providing a better quality of voice and life.

The Use of Vocal Fold Injection Augmentation in a Transmasculine Patient Unsatisfied With Voice Following Testosterone Therapy and Voice Training.

INTRODUCTION: There exist a cohort of transmasculine patients who remain dissatisfied with vocal function following testosterone therapy and voice training. AIM: The objective of this case report was to describe the use of injection laryngoplasty in this cohort as an alternative to laryngeal framework surgery. METHOD: A case report and literature review was undertaken. RESULTS: Our case describes a 45-year-old transmasculine patient who remained unsatisfied with vocal pitch despite testosterone therapy and voice training. On initial presentation, the patient had fundamental frequency (fo) ranging from 70-344 Hz with a mean of approximately 135 Hz on reading, and 146 Hz in monologue. Injection augmentation of the vocal folds under local anesthesia with an injectable carboxymethylcellulose gel (prolaryn) was trialed. Following re-absorption of this, further injection was performed using autologous fat and subsequently a longer acting Calcium Hydroxyapatite injectable (Prolaryn Plus). This was followed by re-injection 1 year later. Patient satisfaction has been sustained throughout this period. Repeat acoustic evaluation in 2019 revealed a mean fo of 108 Hz on reading, 100 Hz in monologue, and a fo range of 85-134 Hz across these tasks. CONCLUSION: This case report presents an alternative surgical intervention to supplement testosterone and voice training in transmasculine patients unsatisfied with vocal function.

Effect of Vocal Therapy Associated With TENS in Women With Behavioral Dysphonia.

PURPOSE: This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) associated with vocal therapy in women with behavioral dysphonia. METHOD: Seventeen women with behavioral dysphonia were divided into an experimental group (n = 8) and a placebo group (n = 9). All were submitted to six sessions of vocal therapy, according to the Comprehensive Voice Rehabilitation Program. In the experimental group, therapy was associated with TENS (30 minutes) and in the placebo group, the electrodes were placed and the equipment remained off. The vocal handicap, the voice through the acoustic and auditory perception evaluation, the electrical activity, and the superficial temperature of the suprahyoid and infrahyoid muscles were evaluated. Pre and post data were compared by parametric and nonparametric tests. RESULTS: There was a decreased in vocal handicap of the placebo group (P = 0.002) and a decreased in the percentage of electrical activity of the right (P = 0.036) and left (P = 0.017) infrahyoid muscles of the experimental group in vowel emission and sequential speech (P = 0.036). There was an increase in temperature in the right infrahyoid region in vowel emission (P = 0.027) and the temperature difference decreased quantitatively between the supra and infrahyoid regions in the experimental group. CONCLUSION: TENS associated with vocal therapy reduced the electrical activity of the infrahyoid muscles and balance the temperature between the supra- and infrahyoid regions in women with behavioral dysphonia.

The Effects of Therapeutic Singing on Vocal Functions of the Elderly: A Study on Korean Elderly.

This study investigated the effects of therapeutic singing as an intervention for improving the vocal functions of the elderly. Data collection for this study took place at five senior community centers in Seoul, South Korea, from August 2018 to March 2019. A total of 54 elderly with healthy voices were assigned to a therapeutic singing group, a general singing group, or a control group, using convenience sampling. The therapeutic singing intervention involved using the Alexander technique, performing oral motor and respiratory exercises, and singing participant-written songs, across 12 sessions. The general singing group sang popular and folk songs of their choice. The control group received no treatment. Using peak expiratory flow rate (PEF) and Praat analysis, the participants' vocal functions were measured before and immediately after the intervention. Vocal function was compared among the groups pre- and post-test; the therapeutic singing group showed statistically significant improvement in all vocal parameters: PEF, maximum phonation time, voice intensity (intensity), fundamental frequency (F0), jitter, shimmer, and noise-to harmonics ratio. The general singing group showed improvement only in F0, jitter, and noise-to harmonics ratio. The control group showed an overall reduction in all vocal functions, with a significant decrease in PEF and intensity, and a decrease in jitter and shimmer. Although singing is considered helpful for the voice health of the elderly, therapeutic singing, which involves posture correction and breathing exercises, is even more effective, thus proving to be a viable intervention for preventive voice care of the elderly.

Can ambulatory biofeedback help a transgender woman speak at a higher pitch?

Purpose: Voice feminization for transgender women remains a challenge. The fundamental frequency of the voice (fo) is one of the main parameters contributing to the perception of gender. One of the aims of voice therapy is to help transgender women acquire a new vocal motor behavior to increase their fo. We hypothesized that ambulatory biofeedback could help extend the new vocal behavior to daily life.Materials and methods: This prospective case study assessed the impact of two weeks of ambulatory vibrotactile biofeedback (VTBF) applied to one transgender woman, following two weeks of voice therapy (three 60-minute sessions). The VTBF was activated when the participant's voice was lower than 150 Hz for more than 500 ms and was accompanied by two 60-minute counseling sessions.Results: The results showed that mean fo monitored in daily activities tended to increase following the two weeks of voice therapy (Δ = 8 Hz or 1 semitone) and then increased significantly immediately after the two weeks of VTBF (Δ = 13 Hz or 1.5 semitones). The increase in mean fo from day to day and the decrease in the activation percentage from the first to the second week of VTBF (Δ = 6%) indicated a gradual integration of the motor behavior, making it possible to achieve the targeted female frequency.Conclusions: The results suggest that ambulatory VTBF helped the participant to generalize the techniques acquired during the voice therapy sessions to real-life communication situations. These results are promising for therapeutic programs that integrate tools that can be used outside the clinical context. Design: Prospective case study.

The Impact of Fish Oil Supplementation on Self-Perception of the Voice in Vocal Performers: A Randomized, Single-Blind, Placebo-Controlled Study.

PURPOSE: Physically active adults have experienced training benefits from fish oil-derived omega-3 fatty acid (FO n3), which may also be of benefit to singers. The purpose of this research study was to determine if self-reported vocal adaptations and body composition changes occur in singers following FO n3 supplementation in conjunction with a singer's normal training regimen. METHOD: Twenty college students, currently enrolled in vocal lessons at a university, were randomized to receive either 3.0 g of FO n3 or placebo, which they took during a 10-week study period. Participants were blinded to group assignment. Participants completed the Reflux Symptom Index (RSI), Singing Voice Handicap Index-10 (SVHI-10), and the Evaluation of Ability to Sing Easily (EASE) and submitted to body composition measures (weight, skeletal mass, and body fat mass) before and after the study period. RESULTS: Sixteen participants completed all parts of the study protocol. Mean compliance for the placebo group (83.9%) and the supplement group (75.2%) was similar. There were no significant differences in body composition measures, RSI scores, and EASE scores between groups. Scores on the SVHI-10 decreased significantly over time for all participants. CONCLUSIONS: Improvements seen in the SVHI-10 were not meaningfully different between the supplement and placebo group, pointing to the benefit of weekly lessons. The lack of changes in the questionnaire scores in the supplement group are partially attributed to the low compliance rate and low sample size, which is supported by the lack of change in the body composition measures.

Effects of Cough Suppression Therapy on Voice Disorder Severity.

OBJECTIVES//HYPOTHESIS: To determine changes in voice severity when treating chronic cough refractory to medical treatment with cough suppression therapy (CST) in patients with chronic cough and voice complaints. Chronic cough has been reported to be refractory to medical treatment and frequently co-occurs with voice disorders. The possible effects of CST on self-assessed changes in chronic cough and voice disorders have not been demonstrated. STUDY DESIGN: Retrospective analysis of the effects of cough suppression therapy (CST) on self-assessed changes in chronic cough and voice disorder severity in patients with both chronic cough and voice disorders. METHODS: Forty-three adult patients with the primary complaint of chronic refractory cough underwent pre- and post-treatment diagnostic examinations, completed pre- and post-treatment Voice Handicap Index-10 (VHI-10) and Cough Severity Index assessments, and were treated by a licensed speech-language pathologist using CST. Twenty-seven subjects were assigned to the cough (C) group and 16 to the cough-voice (CV) group based on the severity of their VHI-10 scores. RESULTS: Post-test analysis showed significant improvement in cough severity for both groups and significant improvement in voice severity for the CV group. The VHI-10 scores for the C group did not change significantly. The median number of treatment sessions was 3, with a range of 1-13 sessions. Correlation between changes in severity and number of treatment sessions was not found to be significant at the tested level. CONCLUSIONS: CST represents a unifying approach for treatment of patients with CRC and comorbid voice disorders. CST offered cross-over effects to the voice when subjects were treated for their primary complaint of chronic cough. This treatment of the primary complaint improves function in systems that share a common pathway. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2747-2751, 2021.
