PURPOSE: This study prospectively assessed the efficacy and safety of 532-nm diode laser glottoplasty in patients with sulcus vocalis. METHODS: A prospective human trial was performed from August 2016 to September 2021. 532-nm diode laser glottoplasty was performed in 30 consecutive patients with sulcus vocalis who suffered from voice problems. Patients underwent acoustic aerodynamic, perceptual, stroboscopic, and Voice Handicap Index-10 (VHI-10) evaluations before and 1, 6, and 12 months after laser glottoplasty. RESULTS: Most subjective parameters showed significant improvement (P < 0.05) at 6 months after laser glottoplasty and remained stable at 12 months. Most objective parameters showed significant improvement (P < 0.05) at 12 months after laser glottoplasty. Complications during follow-up included mild vocal fold vibration reduction in 3.3% of patients (1/30) and persistent vocal fold edema in 3.3% of patients (1/30). CONCLUSIONS: Statistically significant voice improvement at 12 months after 532-nm diode laser glottoplasty was achieved without serious complications.

Current Practices in Voice Data Collection and Limitations to Voice AI Research: A National Survey.

INTRODUCTION: Accuracy and validity of voice AI algorithms rely on substantial quality voice data. Although commensurable amounts of voice data are captured daily in voice centers across North America, there is no standardized protocol for acoustic data management, which limits the usability of these datasets for voice artificial intelligence (AI) research. OBJECTIVE: The aim was to capture current practices of voice data collection, storage, analysis, and perceived limitations to collaborative voice research. METHODS: A 30-question online survey was developed with expert guidance from the voicecollab.ai members, an international collaborative of voice AI researchers. The survey was disseminated via REDCap to an estimated 200 practitioners at North American voice centers. Survey questions assessed respondents' current practices in terms of acoustic data collection, storage, and retrieval as well as limitations to collaborative voice research. RESULTS: Seventy-two respondents completed the survey of which 81.7% were laryngologists and 18.3% were speech language pathologists (SLPs). Eighteen percent of respondents reported seeing 40%-60% and 55% reported seeing >60 patients with voice disorders weekly (conservative estimate of over 4000 patients/week). Only 28% of respondents reported utilizing standardized protocols for collection and storage of acoustic data. Although, 87% of respondents conduct voice research, only 38% of respondents report doing so on a multi-institutional level. Perceived limitations to conducting collaborative voice research include lack of standardized methodology for collection (30%) and lack of human resources to prepare and label voice data adequately (55%). CONCLUSION: To conduct large-scale multi-institutional voice research with AI, there is a pertinent need for standardization of acoustic data management, as well as an infrastructure for secure and efficient data sharing.

Rehabilitation Treatment Specification System for Voice Therapy: Application to Everyday Clinical Care.

PURPOSE: Rehabilitation intervention descriptions often do not explicitly identify active ingredients or how those ingredients lead to changes in patient functioning. The Rehabilitation Treatment Specification System (RTSS) provides guidance to identify the critical aspects of any rehabilitation therapy and supported the development of standardly named ingredients and targets in voice therapy (Rehabilitation Treatment Specification System for Voice Therapy [RTSS-Voice]). This study sought to test the content validity of the RTSS-Voice and determine if the RTSS-Voice can be used to identify commonalities and differences in treatment (criterion validity) across clinicians in everyday clinical practice. METHOD: Five speech-language pathologists from different institutions videotaped one therapy session for 59 patients diagnosed with a voice or upper airway disorder. Specifications were created for each video, and iterative rounds of revisions were completed with the treating clinician and two RTSS experts until consensus was reached on each specification. RESULTS: All 59 sessions were specified without the addition of any targets or ingredients. There were two frequent targets: (a) increased volition and (b) decreased strained voice quality. There were three frequent ingredients: (a) information regarding the patient's capability and motivation to perform a therapeutic behavior, (b) knowledge of results feedback, and (c) opportunities to practice voicing with improved resonance and mean airflow. Across sessions treating vocal hyperfunction, there was large variability across clinicians regarding the types and number of treatment components introduced, types of feedback provided, and vocal practice within spontaneous speech and negative practice. CONCLUSIONS: The RTSS and the RTSS-Voice demonstrated strong content validity, as they comprehensively characterized 59 therapy sessions. They also demonstrated strong criterion validity, as commonalities and differences were identified in everyday voice therapy for vocal hyperfunction across multiple clinicians. Future work to translate RTSS principles and RTSS-Voice terms into clinical documentation can help to understand how clinician and patient variability impacts outcomes and bridge the research-practice gap.

Functional Speech and Voice Disorders: Approaches to Diagnosis and Treatment.

Historically, formal training for speech-language therapists (SLTs) in the area of functional speech and voice disorders (FSVD) has been limited, as has the body of empirical research in this content area. Recent efforts in the field have codified expert opinions on best practices for diagnosing and treating FSVD and have begun to demonstrate positive treatment outcomes. To provide comprehensive interventions for these complex conditions at the intersection of neurology, psychiatry, and other medical specialties, the SLT must not only build knowledge of diagnostic strategies and components of symptomatic treatment in FSVD but also embrace behavior change techniques and counseling strategies.

Feasibility and efficacy of video-call speech therapy in patients with Parkinson's disease: A preliminary study.

BACKGROUND: Speech therapy is highly effective for patients with Parkinson's disease (PD) who have speech difficulties; however, its accessibility is limited. Online video-call speech therapy has been explored as an alternative option for PD patients. OBJECTIVES: To evaluate the feasibility and efficacy of video-call speech therapy for PD patients. METHODS: This prospective, comparative study was conducted between July and September 2022. PD patients with speech difficulties were divided into two groups, online speech therapy via video call and in-person therapy at hospital, based on their willingness to visit the hospital frequently. The patients underwent 12 sessions of speech therapy, focusing on respiration and phonation. Acoustic assessments, auditory-perceptual assessment, and voice handicap index (K-VHI10) were evaluated at baseline, post-therapy, and follow-up. RESULTS: Eleven patients were enrolled in the study, though one patient from the online group withdrew. Ten patients completed the therapy (five in each group) without missing a session. The baseline acoustic measurements did not differ between the two groups. After therapy, both group showed an increase in voice intensity and improvement in overall loudness. The post-therapy change from baseline in the acoustic measurements was not significantly different between the two groups. The effect of therapy were maintained in the follow-up evaluation in both groups. The K-VHI10 decreased significantly from baseline to post-therapy and further at follow-up in both groups, with no significant difference between two groups. CONCLUSION: The online speech therapy via video call is feasible in PD patients with speech difficulties and as effective as in-person therapy.

[Patient-reported outcome measures for assessing health-related quality of life in patients with voice and swallowing disorders]. / Patient-Reported Outcome Measures zur Erfassung der gesundheitsbezogenen Lebensqualität bei Patienten mit Stimm- und Schluckstörungen.

Standardized and validated patient surveys in the form of questionnaires are becoming increasingly important in otorhinolaryngology. Subjective symptoms and functional limitations but also health-related quality of life are assessed with so-called patient-reported outcome measures (PROMs). Besides patient history and objective findings, these questionnaires can be applied as another important source for ensuring the quality of patient-centered care. In German-speaking countries there are now several PROMs that specifically ask for the patient perspective on voice and swallowing disorders. For patients with voice disorders the following questionnaires based on the Voice Handicap Index (VHI), which are also used internationally, are mainly applied: VHI-30, VHI-12i, and VHI-9i. In the field of oropharyngeal dysphagia, the German versions of the Eating Assessment Tool-10 (EAT-10), des Sydney Swallow Questionnaire SSQ­G, the Swallowing Quality of Life Questionnaire (SWAL-QoL), and the MD Anderson Dysphagia Inventory (MDADI) are currently mostly used.

Voice improvement following conventional speech therapy combined with singing intervention in people with Parkinson's disease: A three-arm randomised controlled trial.

BACKGROUND: Although speech and voice disorders are common in Parkinson's disease (PD), there is insufficient evidence to support the effectiveness of behavioural speech therapies in these patients. AIMS: This study aimed to examine the effects of a new tele-rehabilitation program, a combining of conventional speech therapy and singing intervention, on voice deficits in patients with PD. METHODS & PROCEDURES: This study was a three-armed, assessor-masked, randomised controlled trial. Thirty-three people with PD were randomly assigned to the combination therapy, conventional speech therapy, or singing intervention group. This study followed the Consolidated Standards of Reporting Trials guidelines for non-pharmacological treatment. Each patient participated in 12 tele-rehabilitation sessions over 4 weeks. The combination therapy group received speech and singing interventions simultaneously (respiratory, speech, voice, and singing exercises). Voice intensity as a primary outcome and the voice handicap index (VHI), maximum frequency range, jitter and shimmer as secondary outcomes were evaluated 1 week before the first intervention session, 1 week after the last intervention session and 3 months after the last evaluation. OUTCOMES & RESULTS: The results of repeated measures analysis of variance showed a significant main effect of time on all outcomes in all three groups after treatment (p < 0.001). There was a significant group effect for voice intensity (p < 0.001), VHI (p < 0.001), maximum frequency range (p = 0.014) and shimmer (p = 0.001). The combination therapy group demonstrated a significant outperformance in the VHI and shimmer than the speech therapy (p = 0.038) and singing intervention (p < 0.001) groups. The results of this study also indicated that combination therapy group compared to singing intervention group had a larger effect on voice intensity (p < 0.001), shimmer (p < 0.001) and maximum frequency range (p = 0.048). CONCLUSIONS & IMPLICATION: The results demonstrated that combining speech therapy with a singing intervention delivered through tele-rehabilitation might be more effective in improving voice problems in patients with PD. WHAT THIS PAPER ADDS: What is already known on the subject Parkinson's disease (PD) is a neurological disorder that frequently causes disturbances in speech and voice, which negatively affect patients' quality of life. Although speech difficulties occur in 90% of patients with PD, evidence-based treatment options for speech and language problems in these patients are limited. Therefore, further studies are required to develop and assess evidence-based treatment programs. What this study adds The findings of this study showed that a combination therapy program including conventional speech therapy approaches and individual singing intervention provided through tele-rehabilitation may have a greater effect on the improvement of voice problems in people with PD compared to speech therapy and singing intervention alone. What are the clinical implications of this work? Tele-rehabilitation combination therapy is an inexpensive and enjoyable behavioural treatment. The advantages of this method are that it is easy to access, appropriate for many stages of voice problems in PD, requires no prior singing training, encourages voice health and self-management and maximises treatment resources available to people with PD. We believe that the results of this study can provide a new clinical basis for treatment of voice disorders in people with PD.

[Preliminary analysis of the effect of individualized voice therapy on pediatric voice disorders].

Objective:To determine the effectiveness of individualized voice therapy in persistent pediatric voice disorders. Methods:Thirty-eight children who were admitted to the Department of Pediatric Otolaryngology Shenzhen Hospital, Southern Medical University due to persistent voice disorder from November 2021 to October 2022 were included. All children were evaluated by dynamic laryngoscopy before voice therapy. Two voice doctors performed GRBAS score and acoustic analysis on the children's voice samples to obtain the relevant parameters including F0, Jitter, Shimmer, and MPT; All children were given personalized voice therapy for 8 weeks. Results:Among 38 children with voice disorders, 75.8%（29 cases） were diagnosed with vocal nodules, 20.6%（8 cases） were vocal polyps, and 3.4%（1 case） were vocal cysts. And in all children. And 51.7%（20 cases） had the sign of supraglottic extrusion under dynamic laryngoscopy. GRBAS scores decreased from 1.93 ± 0.62, 1.82 ± 0.55, 0.98 ± 0.54, 0.65 ± 0.48, 1.05 ± 0.52 to 0.62 ± 0.60, 0.58 ± 0.53, 0.32 ± 0.40, 0.22 ± 0.36, 0.37 ± 0.36. F0, Jitter, Shimmer decreased from（243.11±39.73） Hz, （0.85±0.99）%, （9.96±3.78）% to（225.43±43.20） Hz, （0.33±0.57）%, （7.72±4.32）%, respectively MPT was prolonged from（5.82±2.30） s to（7.87±3.21） s after treatment. All parameters changes had statistical significance. Conclusion:Voice therapy can solve children's voice problems, improve their voice quality and effectively treat children's voice disorders.

Effect of Ventral Intermediate Nucleus Deep Brain Stimulation on Vocal Tremor in Essential Tremor.

Background: There is a paucity of literature examining the effect of Ventral Intermediate Nucleus (VIM) deep brain stimulation (DBS) on voice in patients with vocal tremor (VT). Objective: Investigate the effect of unilateral and bilateral VIM DBS on voice in patients with Essential Tremor (ET) and VT. Methods: All patients receiving VIM DBS surgery underwent voice evaluation pre- and six-months post-operatively. We collected patient-reported quality-of-life outcome measures and acoustic voice measures of sustained phonation and connected speech. Acoustic measures specific to VT included amplitude tremor intensity index (ATRI), frequency tremor intensity index (FTRI), rate and extent of F0 modulation, and rate and extent of intensity modulation. Results: Five patients, age 72.8 ± 2.6 years, 4 female, 1 male with mean disease duration of 29 ± 26.2 years met the inclusion criteria and were included. Two subjects had bilateral procedure and three had unilateral. We observed significant improvements in measures of vocal tremor including ATRI, FTRI, rate of F0 modulation, rate of intensity modulation, and extent of intensity modulation, as well as patient reported voice-related quality of life measured by VHI-10. Bilateral VIM DBS cases showed greater improvement in VT than unilateral cases. Conclusion: Both unilateral and bilateral VIM DBS resulted in significant improvement of VT, with more improvement demonstrated in patients having bilateral as compared to unilateral VIM DBS. In addition, patients also reported significant improvements in voice-related quality of life. If larger studies confirm our results, VIM DBS has the potential to become a treatment specifically for disabling VT.

Social Determinants of Health: Implications for Voice Disorders and Their Treatment.

PURPOSE: Adverse childhood experiences (ACEs) and related conditions, such as discrimination, are social determinants of health (SDOHs). Critical race theory (CRT) is a lens through which to understand SDOHs in a way that may impact our clinical care. When prolonged or chronic, SDOHs might cause toxic stress and trauma, which, in turn, adversely affect health and are shown to be relevant for some voice disorders. The goals of this tutorial are to (a) review the literature on SDOHs that potentially contribute to disparities; (b) discuss explanatory models and theories that describe how psychosocial factors influence health; (c) relate the foregoing information to voice disorders, highlighting functional voice disorders (FVDs) as a particular case in point; and (d) describe how trauma-informed care can improve patient outcomes and advance health equity for vulnerable populations. CONCLUSIONS: This tutorial concludes with a call for heightened awareness of the role that SDOHs such as structural and individual discrimination may play in voice disorders, and a call for research into SDOHs, traumatic stress, and health disparities in this patient population. A call is also made for more universal practice of trauma-informed care in the clinical voice domain.

Update on the pediatric adverse vocal behavior voice disorders: a clinical practice review.

The main causes of voice disorders in children with adverse vocal behavior include benign lesions of the vocal folds caused by voice abuse or misuses, such as vocal fold nodules, vocal fold polyps, and laryngitis. Long-term voice disorders can affect the physical and mental health of children. Reviewing the literature of the last two decades on "Vocal Fold Nodules," "Vocal Fold Polyp," "Voice disorder," "Voice Abuse," "Voice Misuse," "Pediatrics," and "Children" with the appropriate Boolean operators.  Conclusion: A total of 315 results were returned on an initial PubMed search. All articles from 2000 to 2022 written in English or Chinese were screened. Duplicate articles, those relating to adults only or concerned with the malignant lesion of the vocal cord, were excluded, resulting in 196 articles of interest. Relevant references and books have also been consulted, and we provide a review of the pathogenesis, diagnosis, and treatment of these maladaptive vocal behavioral voice disorders. What is Known: • Hoarseness is the most common voice symptom in children, and there are various causes of hoarseness in children. However, there is a lack of reviews on voice disorders caused by adverse vocal habits in children. • Voice training is a conservative treatment method for children with voice disorders , and it is important to clarify the factors that influence the effectiveness of voice training for children. What is New: • This review of the personality and family characteristics of children with adverse vocal behavioural voice disorders provides a valuable guide to the clinical planning of subsequent treatment. • This article discusses and summarises some of the factors that may influence the effectiveness of voice training in children and collates some of the scales and questionnaires currently used in children that are important in predicting the effectiveness of voice training.

The role of patient perceptions and hyperfunctional voice disorders in predicting voice therapy attendance.

OBJECTIVES/HYPOTHESIS: Attendance is essential to voice therapy's effectiveness in the treatment of voice and laryngeal disorders. With such high rates of drop-out and non-attendance, it is important to understand the factors that influence this behavior. This study sought to identify potential predictors of attendance to voice therapy at an interdisciplinary voice clinic. STUDY DESIGN: Single-institution retrospective cohort study. METHODS: In this retrospective cohort study, patients evaluated at an interdisciplinary voice clinic who received a referral for voice therapy were identified. Age, gender, voice-related diagnoses, Voice Handicap Index-10 scores, Reflux Symptom Index scores, and measures of patient perceptions (self-rated severity, importance of voice in one's life, and "feelings about voice therapy") were recorded to evaluate associations with attendance to at least one therapy session. Standard statistical analysis and logistic regressions were performed. RESULTS: Of 168 subjects included, 111 (66.1 %) attended at least one session of voice therapy. Patients diagnosed with primary hyperfunctional voice disorders had a significantly higher attendance rate than other groups. Attenders had higher self-ratings of severity and more positive "feelings about voice therapy" compared to non-attenders. Regression models found three significant predictors of therapy attendance: primary diagnosis of hyperfunctional voice disorder, self-rated severity, and "feelings about voice therapy." CONCLUSION: In this cohort, patients with more positive feelings about voice therapy, higher self-rated severity, and a diagnosis of primary hyperfunctional voice disorder were more likely to attend voice therapy.

Self-perceived affective, behavioral, and cognitive reactions associated with voice use in people with Parkinson's disease: a pilot study.

PURPOSE: This study aimed to compare the affective, behavioral, and cognitive reactions related to vocal function in people with Parkinson's disease (PWPD) and healthy controls using the Behavior Assessment Battery - Voice (BAB-Voice). The test's internal consistency was also described. METHODS: 31 PWPD and 19 healthy controls were recruited from September 2020 to March 2021. Participants completed four BAB-Voice subtests: Speech Situation Checklist - Emotional Reaction (SSC-ER), the Speech Situation Checklist - Speech Disruption (SSC-SD), Behavior Checklist (BCL), and Communication Attitude Test for Adults (BigCAT), describing the experienced negative emotional reaction, voice disruptions, coping behaviors, and negative attitude regarding communication respectively. Subtest scores were calculated and analyzed. RESULTS: The scores of the PWPD were significantly different from those of the controls (Pillai's Trace = 0.344, F[4] = 5.508, p = .001, ηp2 = .344): PWPD showed more negative emotions and voice problems, more coping behaviors, and more negative speech-related attitude compared to healthy controls. All subtests showed excellent internal consistency. CONCLUSIONS: The BAB-Voice proved a tool with a good internal consistency that measured different psychosocial reactions in PWPD versus controls. PWPD exhibited significantly more negative emotions and voice problems in specific speech situations, more coping behaviors, and a more negative speech-related attitude. The specificity of information obtained from the BAB-Voice may aid in improving the treatment planning of voice disorders in PWPD.

The effects of surface electrical stimulation plus voice therapy in Parkinson's disease.

OBJECTIVE: This study aimed to assess the effects of surface electrical stimulation plus voice therapy on voice in dysphonic patients with idiopathic Parkinson's disease. METHOD: Patients were assigned to 3 treatment groups (n = 28 per group) and received daily treatment for 3 weeks on 5 days a week. All three groups received voice therapy (usual care). In addition, two groups received surface electrical stimulation, either motor-level or sensory-level stimulation. A standardised measurement protocol to evaluate therapeutic effects included the Voice Handicap Index and videolaryngostroboscopy. RESULTS: Voice Handicap Index and videolaryngostroboscopic assessment showed statistically significant differences between baseline and post-treatment across all groups, without any post-treatment differences between the three groups. CONCLUSION: Intensive voice therapy (usual care) improved idiopathic Parkinson's disease patients' self-assessment of voice impairment and the videolaryngostroboscopic outcome score. However, surface electrical stimulation used as an add-on to usual care did not improve idiopathic Parkinson's disease patients' self-assessment of voice impairment or the videolaryngostroboscopic outcome scores any further.

The Evaluation of Beck Anxiety Scale, Voice Handicap Index, and Brief Symptom Inventory on Treatment of Patients With Vocal Fold Nodules.

INTRODUCTION: Vocal fold nodules are benign lesions that cause hoarseness in all age groups including children, adolescents, and adults. These nodules may be caused either by singing or other causes of tension in vocal activity. OBJECTIVE: The aim of this study was to evaluate the psychological symptoms of adult patients with hoarseness and to investigate the relationship in psychological symptoms before and after voice therapy. METHODS: 23 Patients who were admitted with a voice complaint and diagnosed with vocal fold nodules and a matched control group were evaluated. Two inventories recommended by our psychiatrist (The Beck Anxiety Inventory, Brief Symptom Inventory) and Voice Handicap Index-10 (VHI-10), were completed to evaluate the treatment outcomes and psychosocial properties of the patients before and after voice therapy. RESULTS: A significant difference was observed in the BAI and BSI scores between the nodule (+) group and the control group at the beginning of the study, before voice therapy. A significant difference was found between the mean scores on the BAI and the BSI before and after therapy in the vocal fold nodules group. CONCLUSION: Patients with vocal fold nodules should be evaluated more extensively using psychological assessment scales, such as the BSI, and a psychiatric consultation should be added in cases of abnormal findings.

Pediatric Voice Disorders from the Perspective of Rare Diseases.

OBJECTIVE: This study aims to present rare pediatric voice disorders, which are usually reported as case reports in the literature, with their clinical features, treatment options, and prognosis, and to emphasize clinical findings that may be associated with rare diseases. METHODS: The clinical records of the pediatric patients presented with dysphonia were reviewed between 2014 and 2019. The terminology "rare disease" is used to describe diseases where the average prevalence thresholds are between 40 to 50 cases/100,000 people. Age, gender, symptoms, laryngeal examination findings, histopathological results, treatment modalities and follow-up results of rare laryngeal pathologies were reviewed. RESULTS: 274 children were diagnosed with and treated for voice disorders at our institution. Seven patients were identified with rare laryngeal pathologies. Four patients diagnosed with lipoid proteinosis, two patients with neurofibroma and one patient with amyloidosis. One patient was known to have neurofibromatosis type-1, while the others did not have any previously diagnosed diseases, dysphonia was the initial clinical presentation. CONCLUSION: There are some clues that bring to mind rare entities. Firstly, these patients generally present with various systemic manifestations. Secondly, if there is any discrepancy between voice quality and endoscopic laryngeal examination, the diagnosis should be reconsidered. Thirdly, in the case of the prolonged dysphonia recalcitrant to treatment, the clinician should reassess the treatment or the diagnosis.

Airway Management in Singers: A Cross-sectional Survey.

OBJECTIVE: To review and establish current practices regarding airway management in vocal professionals undergoing surgery. STUDY DESIGN: Cross-sectional survey SETTING: The setting included practitioners that treat vocal professionals across international sub-specialty societies. SUBJECTS AND METHODS: A twenty-one-item survey was sent to practitioners that routinely treat vocal professionals including the American Broncho-Esophagological Association, European Laryngological Society, and 2017 Fall Voice Conference attendees. It included questions regarding the respondents' demographics, preferences for airway control in non-laryngeal and laryngeal surgery, and peri-operative management. RESULTS: Total respondents (n = 163): 82.8% were Laryngologists, 4.3 % were General Otolaryngologists, 3.1% were Head & Neck Oncologists, and 6.8% were Speech-Language Pathologists. One hundred twenty-five of the participants (76.7%) classified their experience with vocal professionals as 'extensive' or 'often.' For non-laryngeal surgery, there was a tendency towards laryngeal mask airway (53.1%) over endotracheal intubation (46.9%). For professional singers, a smaller endotracheal tube was recommended. Size varied based on sex. For males, 88.5% recommended a tube ≤7.0 in non-singers; 98.2% recommended a tube ≤7.0 in singers. In females 76.1% recommended a tube ≤6.0 for non-singers; 94.6 % recommended a size ≤6.0 in a female singer. For laryngeal surgery, 14% of providers personally intubated patients over 90% of the time. Of the providers who work with trainees, 60.5% did not allow resident intubation. CONCLUSION: Objective data regarding precautions in airway management of professional voice users is scarce. This is the largest survey to date on current practices. Survey results indicate that smaller ETTs are preferred for singers, and that more experienced practitioners are preferred for the intubation.
