[Analysis of the efficacy of non-surgical treatment mainly focus on voice therapy and it's influencing factors in patients with unilateral vocal fold paralysis].

Objective:Retrospective analysis of the efficacy and it's influencing factors of non-surgical treatment mainly focus on voice therapy for patients with unilateral vocal fold paralysis. Methods:The retrospective study includes 57 patients who were diagnosed with unilateral vocal fold paralysis and presented with hoarseness as their main complaint at the Department of Voice Medicine, Zhongshan Hospital of Xiamen University from August, 2021 to August, 2023. Judging the efficacy of non-surgical treatment mainly focus on voice therapy through changes in acoustic, aerodynamic, and laryngoscopic parameters; Analyze the relationship between patients' age, gender, duration of disease, cause of nerve injury, type of nerve injury, side of nerve injury and efficacy of non-surgical treatment. Results:After non-surgical treatment mainly focused on voice therapy, there were statistically significant differences（P<0.01） in the changes of vocal fold bow, glottal gap, glottal compression, loudness, Jitter, Shimmer, IC, and NC parameters. There is a statistically significant correlation between the duration of the disease and changes in glottal gap, Shimmer, and IC（P<0.05）, the side of nerve injury can affect changes of glottal gap and NC（P<0.05）. Conclusion:Non-surgical treatment mainly focused on voice therapy has a good efficacy on patients with unilateral vocal fold paralysis. The duration of the disease and the side of nerve injury may affect the efficacy.

Floating Ball Voice Therapy: Preliminary Effects on Outcomes and Predicting Individual Patient Differences in Generalization.

PURPOSE: Floating ball voice therapy (FBVT) is a voice-controlled virtual environment based on a common treatment component across multiple evidence-based therapies: improved vocal efficiency (target) via practicing voicing with modified resonance and airflow (ingredient). This study preliminarily tested FBVT's effects on outcomes and the potential for its novel variability metrics to predict individual patient generalization. METHOD: Ten patients with nonphonotraumatic vocal hyperfunction (NPVH) practiced FBVT for 10 days. Outcomes were assessed by a vocal efficiency ratio, a validated NPVH index, the patient-reported Voice-Related Quality of Life (V-RQOL), and forced-choice auditory judgments of overall severity. Exploration in early practice (Day 1) was estimated by how the patient's two-dimensional variability (mean airflow and intensity) related to error (difference between the patient-produced and normative vocal efficiency ratio). Generalization from the game to spontaneous speech was evaluated using the validated NPVH index. RESULTS: Ten days of FBVT were associated with improved vocal efficiency (Cohen's d = 1.3), NPVH index (d = -1.1), V-RQOL total score (d = 0.9), and overall severity (odds ratio = 2.5). Patients who generalized on Day 10 exhibited airflow/intensity exploration that was more aligned with the error gradient on Day 1 (d = 0.6-1.2). CONCLUSIONS: A relatively small dosage of FBVT (i.e., 10 practice sessions) was associated with multiple improved voice therapy outcomes. The FBVT variability metrics on Practice Day 1 demonstrated strong potential to predict which patients generalized to connected speech. Future work can more thoroughly evaluate effects on outcomes and characterizing the quality of vocal exploration with a larger patient population.

Lee Silverman voice treatment versus NHS speech and language therapy versus control for dysarthria in people with Parkinson's disease (PD COMM): pragmatic, UK based, multicentre, three arm, parallel group, unblinded, randomised controlled trial.

OBJECTIVES: To assess the clinical effectiveness of two speech and language therapy approaches versus no speech and language therapy for dysarthria in people with Parkinson's disease. DESIGN: Pragmatic, UK based, multicentre, three arm, parallel group, unblinded, randomised controlled trial. SETTING: The speech and language therapy interventions were delivered in outpatient or home settings between 26 September 2016 and 16 March 2020. PARTICIPANTS: 388 people with Parkinson's disease and dysarthria. INTERVENTIONS: Participants were randomly assigned to one of three groups (1:1:1): 130 to Lee Silverman voice treatment (LSVT LOUD), 129 to NHS speech and language therapy, and 129 to no speech and language therapy. LSVT LOUD consisted of four, face-to-face or remote, 50 min sessions each week delivered over four weeks. Home based practice activities were set for up to 5-10 mins daily on treatment days and 15 mins twice daily on non-treatment days. Dosage for the NHS speech and language therapy was determined by the local therapist in response to the participants' needs (estimated from prior research that NHS speech and language therapy participants would receive an average of one session per week over six to eight weeks). Local practices for NHS speech and language therapy were accepted, except for those within the LSVT LOUD protocol. Analyses were based on the intention to treat principle. MAIN OUTCOME MEASURES: The primary outcome was total score at three months of self-reported voice handicap index. RESULTS: People who received LSVT LOUD reported lower voice handicap index scores at three months after randomisation than those who did not receive speech and language therapy (-8.0 points (99% confidence interval -13.3 to -2.6); P<0.001). No evidence suggests a difference in voice handicap index scores between NHS speech and language therapy and no speech and language therapy (1.7 points (-3.8 to 7.1); P=0.43). Patients in the LSVT LOUD group also reported lower voice handicap index scores than did those randomised to NHS speech and language therapy (-9.6 points (-14.9 to -4.4); P<0.001). 93 adverse events (predominately vocal strain) were reported in the LSVT LOUD group, 46 in the NHS speech and language therapy group, and none in the no speech and language therapy group. No serious adverse events were recorded. CONCLUSIONS: LSVT LOUD was more effective at reducing the participant reported impact of voice problems than was no speech and language therapy and NHS speech and language therapy. NHS speech and language therapy showed no evidence of benefit compared with no speech and language therapy. TRIAL REGISTRATION: ISRCTN registry ISRCTN12421382.

Effects of Speech Characteristics on Electroglottographic and Instrumental Acoustic Voice Analysis Metrics in Women With Structural Dysphonia Before and After Treatment.

PURPOSE: Literature suggests a dependency of the acoustic metrics, smoothed cepstral peak prominence (CPPS) and harmonics-to-noise ratio (HNR), on human voice loudness and fundamental frequency (F0). Even though this has been explained with different oscillatory patterns of the vocal folds, so far, it has not been specifically investigated. In the present work, the influence of three elicitation levels, calibrated sound pressure level (SPL), F0 and vowel on the electroglottographic (EGG) and time-differentiated EGG (dEGG) metrics hybrid open quotient (OQ), dEGG OQ and peak dEGG, as well as on the acoustic metrics CPPS and HNR, was examined, and their suitability for voice assessment was evaluated. METHOD: In a retrospective study, 29 women with a mean age of 25 years (± 8.9, range: 18-53) diagnosed with structural vocal fold pathologies were examined before and after voice therapy or phonosurgery. Both acoustic and EGG signals were recorded simultaneously during the phonation of the sustained vowels /ɑ/, /i/, and /u/ at three elicited levels of loudness (soft/comfortable/loud) and unconstrained F0 conditions. RESULTS: A linear mixed-model analysis showed a significant effect of elicitation effort levels on peak dEGG, HNR, and CPPS (all p < .01). Calibrated SPL significantly influenced HNR and CPPS (both p < .01). Furthermore, F0 had a significant effect on peak dEGG and CPPS (p < .0001). All metrics showed significant changes with regard to vowel (all p < .05). However, the treatment had no effect on the examined metrics, regardless of the treatment type (surgery vs. voice therapy). CONCLUSIONS: The value of the investigated metrics for voice assessment purposes when sampled without sufficient control of SPL and F0 is limited, in that they are significantly influenced by the phonatory context, be it speech or elicited sustained vowels. Future studies should explore the diagnostic value of new data collation approaches such as voice mapping, which take SPL and F0 effects into account.

Effect of voice training intervention on swallowing function in patients with head and neck cancer undergoing radiotherapy: A randomized controlled trial.

PURPOSE: We aimed to evaluate the effect of voice training in patients with head and neck cancer who were undergoing radiotherapy. METHOD: This study used a randomized controlled trial design. IBM SPSS 26.0 was used to randomly divide 74 patients into a control group and an experimental group. The control group followed a swallowing exercises program, and the experimental group additionally received ABCLOVE voice training. Both training programs continued throughout the entire radiotherapy cycle. We compared standardized swallowing assessment (SSA), maximum phonation time (MPT), the Voice Handicap Index-10, and incidence of complications such as difficulty opening the mouth, malnutrition, and aspiration between the two groups at T1 (0 radiotherapy sessions, before radiotherapy), T2 (15-16 radiotherapy sessions, middle of radiotherapy), and T3 (30-32 radiotherapy sessions, end of radiotherapy). RESULTS: 70 participants completed this study. Swallowing function and MPT intergroup and interaction effects were statistically significant between the two groups (P < 0.05). At the end of radiotherapy (T3), the SSA score (20.77 ± 1.96) and MPT (10.98 ± 1.75) s in the experimental group were superior to those in the control group (SSA: 22.06 ± 2.38 and MPT: 9.49±1.41 s), with statistical significance (P<0.05). Moreover, the incidence of malnutrition and aspiration in the experimental group was lower than that in the control group (P < 0.05). CONCLUSION: Voice training can improve swallowing function and MPT and reduce complications related to swallowing disorders in patients with head and neck cancer.

Rehabilitation Treatment Specification System: Content and Criterion Validity Across Evidence-Based Voice Therapies for Muscle Tension Dysphonia.

PURPOSE: Systematically improving voice therapy outcomes is challenging as the clinician actions (i.e., active ingredients) responsible for improved patient functioning (i.e., targets) are relatively unknown. The theory-driven Rehabilitation Treatment Specification System (RTSS) and standard, voice-specific terminology based on the RTSS (RTSS-Voice) may help address this problem. This qualitative study evaluated if the RTSS and RTSS-Voice can describe four evidence-based voice therapies for muscle tension dysphonia without missing critical aspects (content validity) and identify commonalities and differences across them (criterion validity). METHOD: Qualitative interviews were completed between the clinicians (protocol experts) who developed and/or popularized the vocal function exercises, laryngeal reposturing, circumlaryngeal massage, and conversation training therapies as well as RTSS experts to produce RTSS specifications that met two consensus criteria: (a) The protocol expert agreed that the specification represented their treatment theory, and (b) the RTSS experts agreed that the specifications correctly adhered to both the RTSS framework and the RTSS-Voice's standard terminology. RESULTS: The RTSS and RTSS-Voice comprehensively described voice therapy variations across and within the four diverse treatment programs, needing only the addition of one new target: overall auditory-perceptual severity. CONCLUSIONS: The RTSS and RTSS-Voice exhibited strong content validity. The standard RTSS-Voice terminology helped identify, for the first time, commonalities and differences in treatment ingredients, targets, and mechanisms of action across four treatments developed for the same patient population. In the long term, the RTSS and RTSS-Voice could provide the framework for an ever-growing collection of clinically meaningful and evidence-based therapy algorithms with potential to improve research, education, and clinical care.

Therapeutic Singing and Semi-Occluded Vocal Tract Exercises for Individuals with Parkinson's Disease: A Randomized Controlled Trial of a Single Session Intervention.

Individuals with Parkinson's disease (PD) experience speech and voice-related symptoms that diminish communication and quality of life. Semi-occluded vocal tract (SOVT) exercises are targeted interventions that, when combined with the positive psychosocial benefits of therapeutic group singing (TGS), may affect outcomes. The purpose of this study was to explore the effectiveness of SOVT exercises, specifically straw phonation combined with TGS, to improve voice quality and mood for individuals with PD. We used a true experimental pretest-posttest between-subjects design (i.e., randomized controlled trial) facilitated by a board-certified music therapist. All participants (N = 27) were randomly assigned to one of three groups (a) straw phonation combined with TGS (SP + TGS, n = 10), (b) TGS (n = 10), and (c) speaking-only control group (n = 7). Participants completed voice recordings for acoustic measures and the Visual Analogue Mood Scale for mood analysis before and after a 30-min intervention. The results demonstrated significant improvement in voice quality evidenced by decreasing Acoustic Voice Quality Index scores following a single session for both SP + TGS and TGS intervention groups when compared to the control. Happiness scores improved in the experimental groups when compared to control. Although not statistically significant, participants in the experimental groups (SP + TGS, TGS) demonstrated better mean mood scores on happiness, anxiety, and angry when compared to control, indicating a positive psychological response to the singing interventions. Overall, this study indicated the effectiveness of SP + TGS and TGS as promising therapeutic interventions for voice quality and mood in individuals with PD.

¿Notas La Diferencia? [Do You Hear the Difference?]: Perceptual Consequences of Intensive Voice Treatment in Spanish Speakers With Parkinson's Disease.

PURPOSE: The primary objective of this study was to explore the effects of intensive voice-focused treatment on speech parameters in Spanish speakers with dysarthria associated with Parkinson's disease (PD) as perceived by naïve listeners. METHOD: Fifteen Spanish speakers with dysarthria associated with PD received the Lee Silverman Voice Treatment (LSVT LOUD) for a month. Voice and speech recordings were conducted pretreatment, posttreatment, and at a 1-month follow-up. Thirty naïve adult listeners rated the perceptual dimensions of ease of understanding (EoU), resonance, articulatory precision, prosody, and voice quality from sentences extracted from an emotional monologue on a visual analogue scale. RESULTS: EoU, resonance, articulatory precision, and voice quality significantly improved pre- to posttreatment, but gains were not maintained at follow-up. Speech severity was a significant source of variance in mean listener response for all perceptual dimensions, although the interaction between speech severity and time was only significant for resonance and voice quality. CONCLUSIONS: LSVT LOUD may be beneficial to improve perceptual speech domains affected by PD in Spanish speakers with dysarthria. Its impact on the different speech subsystems may reflect a universal distribution of effects when directly targeting the glottal source. Language-specific contributions of each perceptual domain to speech intelligibility should be explored in further research to determine linguistically sensitive treatment targets.

Clinical effectiveness of telerehabilitation in voice therapy programs for dysphonia.

PURPOSE: The main aim of this study was to investigate the clinical efficacy of speech therapy, delivered via tele-practice to patients with dysphonia. A secondary aim was to verify whether a telerehabilitation-only protocol could have a clinical efficacy similar to a combined telerehabilitation and in-person approach. METHODS: Thirty-two consecutive patients undergoing telerehabilitation for dysphonia were retrospectively considered. Patients were divided into two groups: those who received combined in-person and telerehabilitation treatment, and those who underwent telerehabilitation only. RESULTS: Overall, patients included in this study showed a significant improvement in their VHI-10 scores after treatment (p < 0.001). Such an improvement was also significant in both combined therapy and telerehabilitation only groups (p = 0.019, and p = 0.002, respectively). A significant reduction in general degree of dysphonia (G), roughness (R), breathiness (B) and strain (S) scores (p < 0.001, p = 0.012, p < 0.001, and p < 0.001, respectively) was noticed over the whole sample after treatment. The same parameters showed a significant improvement also in the combined therapy group, while in the telerehabilitation only group, only G, B and S scores significantly improved. Mean phonation time, Jitter and Shimmer values significantly improved in the overall sample as well as in the combined therapy group. A significantly more favorable spectrographic class relative to the vowel /a/ was found after treatment in the whole sample, as well as in both combined therapy and telerehabilitation only groups (p < 0.001, p = 0.002, p = 0.004, respectively). CONCLUSION: This study's results seem to support telerehabilitation as a potentially effective tool to administer speech therapy in dysphonic patients, both as a single modality and in combination with traditional in-person sessions. To better characterize the clinical results of telerehabilitation in dysphonia treatment, large-scale prospective investigations are mandatory.

The impact of PD Check-In on self-management skills for maintenance of speech after intensive treatment.

BACKGROUND: Maintenance of speech outcomes following speech-language therapy (SLT) in Parkinson's disease (PD) is an unmet expectation of people with PD (PWPD) and poorly defined in SLT practice. PD Check-In, a model for supported self-managed maintenance of speech following Lee Silverman Voice Treatment (LSVT) LOUD was investigated. AIMS: To investigate the impact of the semi-structured component of PD Check-In on the adoption of self-management concepts and behaviours and the identification of facilitators, barriers and strategies for speech maintenance by PWPD over 24 months post-treatment. METHODS AND PROCEDURE: Following LSVT LOUD, 16 PWPD participated in individual PD Check-In semi-structured discussions with a SLT at 6 and 12 weeks, and 6, 12 and 24 months post treatment. A two-stage qualitative content analysis was applied: directed content analysis using categories from the theoretical framework of PD Check-In followed by inductive content analysis to identify subcategories. OUTCOMES AND RESULTS: Statements from PWPD indicated adoption of seven concepts of self-management across participants and across time. Six concepts from the theoretical framework of PD Check-In (partnerships, self-reflection, maintenance barriers and facilitators, revision of LSVT LOUD skill, goal setting and maintenance strategies), and one new category, participation, emerged from the analysis. Self-reflection, maintenance facilitators and barriers and participation were most prevalent in discussions. PWPD identified facilitators, barriers and strategies for maintenance across time points. CONCLUSIONS AND IMPLICATIONS: Statements from PWPD indicated a positive impact of SLT-supported self-management of speech using self-tailored strategies for sustainable maintenance according to their individual circumstances and needs. WHAT THIS PAPER ADDS: What is already known on this subject People with Parkinson's disease (PWPD) have expressed their need for speech-language therapy (SLT) services that are accessible for the duration of the condition and responsive to their expectation of maintaining speech following treatment. Outcomes for maintenance of the treatment effect following Lee Silverman Voice Treatment (LSVT) LOUD are variable. What this paper adds to existing knowledge This study presents the outcomes of five PD Check-In interventions delivered in semi-structured discussions between PWPD and a SLT over 24 months following LSVT LOUD for the development of self-management skills and behaviours. PWPD adopted self-management positively using self-tailored strategies for sustainable maintenance according to their individual circumstances and needs. What are the potential or actual clinical implications of this work? PWPD responded positively to the individual development of self-management skills and behaviours over time. Individuality and flexible responsivity are features of PD Check-In which resonate with PWPD and speak to SLT supported self-managed maintenance of speech as a long-term model for PD.

Current approaches to gender-affirming vocal care.

PURPOSE OF REVIEW: This review addresses the challenges faced by transgender women in achieving congruence between gender identity and voice characteristics and emphasizes the importance of a multidisciplinary approach involving therapeutic and surgical interventions. RECENT FINDINGS: Recent literature on gender-affirming vocal care emphasizes key themes such as assessment, voice feminization therapy, and various surgical techniques, including glottoplasty and its modifications. Recent publications focused on outcomes, duration, and impact on vocal quality and scrutinized complications associated with surgical interventions. SUMMARY: Most publications in the last 18 months advocate for the integration of voice therapy and surgery for optimal outcomes. Utilising a combined approach is significantly more effective in terms of fundamental frequency gain compared to therapy alone. Modified Wendler's glottoplasty remains the preferred and most reliable surgical intervention. However, surgery is not without its complications and vocal trade-offs, in particular, its impact on vocal projection and the risk of long-term dysphonia. Postsurgery rehabilitation improves long-term outcomes. Recent publications on alternative surgical approaches, namely laser reduction glottoplasty and feminization laryngoplasty, show promise but the results are more difficult to generalise. FUTURE DIRECTION: Prospective multicentre studies with standardized protocols are needed to establish best evidence-based practices.

The Use of the Voice Trainer App for Vocal Control in People with a Degenerative Ataxia: A Pilot Intervention Study.

Dysarthria is disabling in persons with degenerative ataxia. There is limited evidence for speech therapy interventions. In this pilot study, we used the Voice trainer app, which was originally developed for patients with Parkinson's disease, as a feedback tool for vocal control. We hypothesized that patients with ataxic dysarthria would benefit from the Voice trainer app to better control their loudness and pitch, resulting in a lower speaking rate and better intelligibility. This intervention study consisted of five therapy sessions of 30 min within 3 weeks using the principles of the Pitch Limiting Voice Treatment. Patients received real-time visual feedback on loudness and pitch during the exercises. Besides, they were encouraged to practice at home or to use the Voice trainer in daily life. We used observer-rated and patient-rated outcome measures. The primary outcome measure was intelligibility, as measured by the Dutch sentence intelligibility test. Twenty-one out of 25 included patients with degenerative ataxia completed the therapy. We found no statistically significant improvements in intelligibility (p = .56). However, after the intervention, patients were speaking slower (p = .03) and the pause durations were longer (p < .001). The patients were satisfied about using the app. At the group level, we found no evidence for an effect of the Voice trainer app on intelligibility in degenerative ataxia. Because of the heterogeneity of ataxic dysarthria, a more tailor-made rather than generic intervention seems warranted.

Behavioral Management of Respiratory/Phonatory Dysfunction for Dysarthria Associated With Neurodegenerative Disease: A Systematic Review.

PURPOSE: This systematic review represents an update to previous reviews of the literature addressing behavioral management of respiratory/phonatory dysfunction in individuals with dysarthria due to neurodegenerative disease. METHOD: Multiple electronic database searches and hand searches of prominent speech-language pathology journals were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. RESULTS: The search yielded 1,525 articles, from which 88 met inclusion criteria and were reviewed by two blinded co-investigators. A large range of therapeutic approaches have been added to the evidence base since the last review, including expiratory muscle strength training, singing, and computer- and device-driven programs, as well as a variety of treatment modalities, including teletherapy. Evidence for treatment in several different population groups-including cerebellar ataxia, myotonic dystrophy, autosomal recessive spastic ataxia of Charlevoix-Saguenay, Huntington's disease, multiple system atrophy, and Lewy body dementia-were added to the current review. Synthesis of evidence quality provided strong evidence in support of only one behavioral intervention: Lee Silverman Voice Treatment Program (LSVT LOUD) in people with Parkinson's disease. No other treatment approach or population included in this review demonstrated more than limited evidence, reflecting that these approaches/populations require urgent further examination. CONCLUSION: Suggestions about where future research efforts could be significantly strengthened and how clinicians can apply research findings to their practice are provided.

Immediate Effects of Semi-Occluded Vocal Tract Exercises on Acoustic, Auditory-Perceptual, and Self-Perceptual Measures of Voice Production.

INTRODUCTION: This study examined the immediate acoustic, auditory-perceptual, and self-perceptual effects of two semi-occluded vocal tract exercises (SOVTs): straw phonation and straw phonation into a cup of water, delivered in a remote setting. METHOD: Thirty-six participants (19 females and 17 males) completed a baseline battery of acoustic recordings, followed by one of two SOVTs, and an identical post-task battery. The procedure repeated itself to include the other SOVT. Participants were also asked to rate their self-perceived vocal effort and quality following each condition. Recordings were presented to three expert listeners for completion of auditory-perceptual analysis. RESULTS: Acoustically, a significant decrease in shimmer was noted following straw phonation. Auditory-perceptual analysis revealed a significant increase in the perception of strain following straw phonation into a cup of water. While no significant differences were found between SOVT tasks in self-perception of vocal effort, a significant increase in self-perception of vocal loudness was reported following straw phonation into a cup of water. CONCLUSION: SOVTs have a varied, yet significant short-term impact across acoustic, auditory-perceptual, and self-perceptual measures of voice production. Straw phonation provided consistently significant acoustic results, with nearly every variable improving to some degree. Results also support the notion that shimmer is an acoustic measure that is particularly susceptible to change following modest manipulation. These results, in addition to the auditory-perceptual and self-perceptual findings, have a direct impact on how SOVTs are being used clinically and may generalize to inform the way voice metrics are collected and analyzed.

Remote Voice Therapy With an Oscillatory Positive Expiratory Pressure Device in Subjects With Vocal Fatigue: A Randomized Controlled Trial.

PURPOSE: The present study aimed at assessing the efficacy of remote voice therapy (telepractice) implemented with Shaker Medic Plus device in subjects with vocal fatigue. METHOD: Thirty-six participants were initially enrolled in this study. Twenty-four participants with vocal fatigue were finally randomly assigned to one of two treatment groups: (a) voice treatment with Shaker Medic Plus device plus vocal hygiene program (n = 12) and (b) voice treatment with water resistance therapy (WRT) plus vocal hygiene program (n = 12). Laryngoscopic assessment was conducted on all subjects. Before and after voice therapy, participants underwent (a) self-assessment of voice: Vocal Fatigue Index and Vocal Tract Discomfort Scale and (b) instrumental assessment with aerodynamic, acoustic, and electroglottographic measures. The treatment period included six voice therapy sessions within 6 weeks. Each session lasted 30 min. For both groups, exercises consisted of a sequence of nine phonatory tasks performed with Shaker Medic Plus (experimental group) and WRT (control group). Comparisons for all variables were performed between the experimental group and control group. RESULTS: Significant improvements were found for self-reported variables when comparing pre- and postmeasures for both groups. No significant differences were found when comparing groups. No significant main effects or interactions were observed for any of the observed instrumental variables. CONCLUSIONS: Remote physiologic voice therapy with Shaker Medic Plus device and water resistance therapy seem to be both effective to improve voice in subjects diagnosed with vocal fatigue. No differences should be expected between these therapeutic protocols when treating patients with vocal fatigue. Moreover, both are effective at reducing tiredness of voice, voice avoidance, physical discomfort associated with voicing, subjective perception of sensory discomfort in throat, and reduction of physical, emotional, and functional impact of voice problems.

Speech therapy assistance to the transgender population: an experience report / Atendimento fonoaudiológico à população transgênera: um relato de experiência

An incompatible voice with one's own identity is a theme frequently pointed out by the transgender population in speech therapy sessions. Speech therapy is a technique that allows the adjustment of the speaker's voice within a range of possibilities. The speech-language pathologist's role is to provide training, guidance, and counseling to this population, taking into account the specificities of each individual. In light of this, this study aims to report the experience of undergraduate students and speech-language professionals in providing care to the transgender population in a communication laboratory. Initially, key concepts, such as the differences between sex, gender, gender identity, and sexual orientation, are presented. Topics addressed include the violence suffered by the transgender population, the pursuit of vocal adaptation, the creation and development of the communication clinic, the support and assistance provided by professionals to the transgender population and their families, as well as the procedures adopted by the clinic. Among the conclusions, it is highlighted that speech therapy has demonstrated the importance of individual-centered care, legitimizing the guarantee of promoting the users' health. Furthermore, the importance of the speech-language professional in the vocal and communicative improvement of this population, which is often stigmatized, is emphasized (AU).

Voz incompatível com a própria identidade é um tema frequentemente apontado pela população transgênera em atendimentos fonoaudiológicos. A fonoterapia é uma técnica que permite a adequação da voz do falante, dentro de um campo de possibilidades. Ao fonoaudiólogo cabe o treinamento, a orientação e o aconselhamento dessa população, levando em conta as especificidades de cada indivíduo. Diante disso, este estudo tem como objetivo relatar a experiência de estudantes de graduação e profissionais de Fonoaudiologia no atendimento voltado à população transgênera em um laboratório de comunicação. Inicialmente são apresentados conceitos-chave, tais como as diferenças entre sexo, gênero, identidade de gênero, e orientação sexual. São abordados temas como a violência sofrida pela população trans, a busca pela adequação vocal, a criação e o desenvolvimento do ambulatório de comunicação, o acolhimento e o suporte prestado pelos profissionais à população trans e a seus familiares, além dos procedimentos adotados pelo ambulatório. Dentre as conclusões, destaca-se que a assistência fonoaudiológica tem mostrado a importância do cuidado centrado no indivíduo, legitimando a garantia da promoção de saúde dos usuários. Ademais, é destacada a importância do profissional de fonoaudiologia no aprimoramento vocal e comunicativo dessa população que é frequentemente estigmatizada (AU).

Gender-Affirming Voice Training for Trans Women: Effectiveness of Training on Patient-Reported Outcomes and Listener Perceptions of Voice.

PURPOSE: Although speech-language pathologists have provided gender-affirming voice training for trans women since the 1970s, evidence for this training's effectiveness remains weak. Our study aimed to redress limitations of earlier studies and evaluate voice training effects on outcomes important to trans women. METHOD: Seventy-four trans women (19-54 years old) who wanted a more female-sounding voice were recruited through two health facilities and provided with an eight- to 12-session voice training program based on contemporary literature, usual clinical practice, and client-centered care principles. Self-reported outcomes and an audio-recorded reading sample were collected 3 months before, immediately before and after, and 3 months after training. Forty cisgender speakers were audio-recorded reading the same sample material as comparison voices. Seventy-nine naive listeners made gender-related voice ratings of an extract from these audio recordings. Training effectiveness was evaluated using group-level analyses (linear mixed-effects models) and individual-level analyses to establish what proportion of participants improved to a predetermined relevant degree. RESULTS: Group-level analyses demonstrated positive training effects, maintained 3 months posttraining, for trans women's vocal satisfaction, perceptions of voice-related social participation, and self- and listener perceptions of their voices. Individual-level analyses also demonstrated positive effects. Two thirds of trans women increased vocal satisfaction to a relevant degree, one third who reported restricted social participation before training reduced this restriction to a relevant degree, and all were rated more female-sounding after training (although not all to a relevant degree). CONCLUSIONS: All trans women participants made progress toward their voice goals and maintained those gains at follow-up. These findings provide evidence that gender-affirming speech-language pathology services warrant prioritization. Further research is warranted to investigate factors predicting outcomes of voice training for trans women.

A 4-Week Straw Phonation in Water Exercise Program for Aging-Related Vocal Fold Atrophy.

PURPOSE: This study evaluated the efficacy of a 4-week straw phonation in water (SPW) exercise program on aging-related vocal fold atrophy (VFA), with a secondary objective to examine the immediate effects of SPW exercises. METHOD: Thirty-eight older adults aged 60 years and above formally diagnosed with aging-related VFA were randomly assigned into an experimental group undergoing SPW exercises with an 8-cm depth of straw submersion into water for 4 weeks plus vocal hygiene practice (n = 20), and a control group with only vocal hygiene practice (n = 18). Outcome measures included laryngeal endoscopic measures of glottal gap, auditory-perceptual ratings of voice quality, acoustic measures, aerodynamic measures, and standardized self-assessment questionnaire scores. An additional round of acoustic and aerodynamic assessment following 20 min of SPW exercises was conducted to examine the immediate effects. RESULTS: Significant improvements in normalized glottal gap area, perceptual rating of breathiness, smoothed cepstral peak prominence, harmonics-to-noise ratio (HNR), mean oral airflow, subglottal pressure and laryngeal airway resistance at comfortable loudness, Voice-related Quality of Life scores, and Chinese Vocal Fatigue Index Factor 3 scores were observed in the experimental group relative to the control group. There were also significant immediate effects for HNR, mean oral airflow, subglottal pressure, and laryngeal airway resistance. CONCLUSIONS: These findings suggested significant immediate improvements in vocal function following SPW exercises, with additional significant improvements in vocal function as well as significant improvements in quality of life following the 4-week SPW exercise program. Further studies with more long-term follow-up are recommended to better understand the efficacy of SPW exercises with deep levels of straw submersion into water as an effective clinical option for the management of hypofunctional dysphonia associated with aging-related VFA.
