Abstract
OBJECTIVES The paralaryngeal muscles are thought to be hyperfunctional with phonation in patients with primary muscle tension dysphonia (pMTD). However, objective, quantitative tools to assess paralaryngeal movement patterns lack. The objectives of this study were to (1) validate the use of optical flow to characterize paralaryngeal movement patterns with phonation, (2) characterize phonatory optical flow velocities and variability of the paralaryngeal muscles before and after a vocal load challenge, and (3) compare phonatory optical flow measures to standard laryngoscopic, acoustic, and self-perceptual assessments. METHODS Phonatory movement velocities and variability of the paralaryngeal muscles at vocal onsets and offsets were quantified from ultrasound videos and optical flow methods across 42 subjects with and without a diagnosis of pMTD, before and after a vocal load challenge. Severity of laryngoscopic mediolateral supraglottic compression, acoustic perturbation, and ratings of vocal effort and discomfort were also obtained at both time points. RESULTS There were no significant differences in optical flow measures of the paralaryngeal muscles with phonation between patients with pMTD and controls. Patients with pMTD had significantly more supraglottic compression, higher acoustic perturbations, and higher vocal effort and vocal tract discomfort ratings. Vocal load had a significant effect on vocal effort and discomfort but not on supraglottic compression, acoustics, or optical flow measures of the paralaryngeal muscles. CONCLUSION Optical flow methods can be used to study paralaryngeal muscle movement velocity and variability patterns during vocal productions, although the role of the paralaryngeal in pMTD diagnostics (e.g., vocal hyperfunction) remains suspect.

Abstract
PURPOSE To identify vocal sensory symptoms, vocal fatigue, and vocal habits, compare and correlate them in university professors who have passed or failed a screening related to vocal symptoms. STUDY DESIGN Cross-sectional, quantitative, non-randomized study. METHODS The professors responded to four vocal self-assessment Patient-Reported Outcome Measures (PROM): the Brazilian validated version of the Voice Symptom Scale (VoiSS), the Brazilian version (not validated) of the Vocal Tract Discomfort Scale, the Brazilian validated version of the Vocal Fatigue Index and the validated version of the Vocal Health and Hygiene Questionnaire ("Questionário de Saúde e Higiene Vocal - QSHV," in Portuguese). After the PROM's application, the professors were divided into two groups from the VoiSS cutoff point. G1 was formed by professors who passed in the VoiSS screening, that is, those who achieved a total score below 16 points, and G2, formed by professors who failed, that is, those who achieved 16 points or more. The Mann-Whitney U test was used to compare the values of PROM between G1 and G2 groups, and the Spearman correlation test was used to correlate the PROM with one another. RESULTS One hundred and two professors filled in the PROM, 23 from G1 and 79 from G2. Results showed that the total scores of all PROM used exceeded their cutoff scores in the overall sample. It was also observed that professors who failed the screening through VoiSS presented higher scores of vocal sensory symptoms and vocal fatigue, however no differences regarding knowledge on vocal health and hygiene were noticed. In G1, the protocols showed significant correlations ranging from moderate to very strong with one another, but the QSHV showed no correlation with any of the instruments. In G2, the protocols presented weak to strong correlation ratios, and the QSHV reported correlation with all protocols, except for Vocal Fatigue Index. CONCLUSION University professors presented scores higher than the cut-off point suggested by the literature for vocal sensory symptoms, vocal fatigue and knowledge on vocal health and hygiene. Professors who failed the screening performed through VoiSS achieved higher scores of vocal discomfort and fatigue, but also presented a high score for knowledge on vocal hygiene. There was a moderate to very strong statistical correlation among the vocal symptoms, discomforts, vocal fatigue and vocal habits in professors who failed the screening through VoiSS, however among those professors who passed the screening, knowledge on vocal health and hygiene showed no correlation with the PROM analyzed.

Abstract
INTRODUCTION Vocal tract discomfort (VTD), dysphonia, and laryngopharyngeal reflux (LPR) symptoms are complaints frequently reported by amateur singers. There are two aims of this study. The first is to evaluate the prevalence of these symptoms using validated questionnaires. The second is to correlate singing-related variables with the questionnaire responses. METHODS A total of 392 amateur choir singers (ACS) and 514 control subjects completed an online survey divided into four parts: (1) clinical and demographic characteristics, (2) training in singing and singing experience, (3) history of gastroesophageal reflux disease and LPR symptoms, (4) validated questionnaires. Specifically, the reflux symptom index (RSI), the vocal tract discomfort scale (VTDS), and the voice symptom scale (VoiSS) were included to analyze the actual burden related to LPR symptoms, VTD, and dysphonia. RESULTS ACS demonstrated a healthier lifestyle and a lower prevalence of gastroesophageal reflux disease symptoms in comparison with control subjects. ACS scored significantly higher in VTDS and VoiSS than control subjects, while no differences in the RSI results were found. Significant correlations among the questionnaires' results were demonstrated. Occasional professional singing was the variable influencing VTDS and VoiSS results the most. CONCLUSION ACS do not evidently manifest a higher impairment connected to LPR (RSI score), while they do report higher levels of voice (VoiSS score) and vocal tract (VTDS score) impairments, in comparison with control subjects. The relevant correlations among the PRO measures suggest that LPR symptoms, VTD, and dysphonia are related to each other. Given the relevant repercussion on the severity of VTD and dysphonia, providers should specifically ask about occasional professional singing when treating amateur singers.

Reducing Vocal Fatigue While Preserving Realism During Video Game Voice-Overs Using the Vocal Combat Technique: A Randomized Controlled Trial. J Voice 2023:S0892-1997(23)00214-X. [PMID: 37550111 DOI: 10.1016/j.jvoice.2023.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 07/05/2023] [Accepted: 07/06/2023] [Indexed: 08/09/2023]
Abstract
OBJECTIVE Vocal Combat Technique (VCT) teaches indirect and direct behavioral voice techniques to voice-over artists performing in violent video games. Although previous work on VCT has shown promise for mitigating dysphonia symptoms, a randomized clinical trial has yet to be undertaken. Therefore, we completed a randomized, controlled trial between a group of experienced video game voice-over actors receiving VCT and a control group comparison. METHODS A total of 24 video game voice-over actors completed this study. Participants were randomly assigned to receive VCT or indirect vocal hygiene training prior to completing an intensive 1-hour video game voice recording session. The primary outcome was a change in Voice Handicap Index-10 (VHI-10) preperformance/postperformance. Secondary measures included a modified version of the Evaluation of the Ability to Sing Easily (m-EASE), the Vocal Tract Discomfort Scale (VTDS), and questions regarding return to work. Participants were also rated on the realism of their vocal performance by a blinded video game director. RESULTS The VCT group showed a significantly smaller change in VHI-10 and m-EASE scores postperformance, and a higher increased likelihood to return to work compared to the control group. There were no group differences for VTDS or realism ratings. Four participants from the control group exhibited outlier behavior with more pronounced phonotraumatic symptoms following performance than all other participants. CONCLUSIONS VCT shows evidence of mitigating symptoms of dysphonia while preserving the realism of the vocal performance. More work is needed to understand performers at risk for more severe vocal symptoms following extreme voice-over work, so as to target them for preventative techniques and voice preservation.

A mixed-method feasibility study of the use of the Complete Vocal Technique (CVT), a pedagogic method to improve the voice and vocal function in singers and actors, in the treatment of patients with muscle tension dysphonia: a study protocol. Pilot Feasibility Stud 2023; 9:88. [PMID: 37226281 DOI: 10.1186/s40814-023-01317-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 05/02/2023] [Indexed: 05/26/2023] Open
Abstract
BACKGROUND Muscle tension dysphonia (MTD) results from inefficient or ineffective voice production and is the cause of voice and throat complaints in up to 40% of patients presenting with hoarseness. Standard treatment is voice therapy (SLT-VT) delivered by specialist speech therapists in voice disorders (SLT-V). The Complete Vocal Technique (CVT) is a structured, pedagogic method which helps healthy singers and other performers optimise their vocal function enabling them to produce any sound required. The aim of this feasibility study is to investigate whether CVT administered by a trained, non-clinical CVT practitioner (CVT-P) can be applied to patients with MTD before progressing to a pilot randomised control study of CVT voice therapy (CVT-VT) versus SLT-VT. METHODS/DESIGN In this feasibility study, we use a mixed-method, single-arm, prospective cohort design. The primary aim is to demonstrate whether CVT-VT can improve the voice and vocal function in patients with MTD in a pilot study using multidimensional assessment methods. Secondary aims are to assess whether (1) a CVT-VT study is feasible to perform; (2) is acceptable to patients, the CVT-P and SLT-VTs; and (3) whether CVT-VT differs from existing SLT-VT techniques. A minimum of 10 consecutive patients with a clinical diagnosis of primary MTD (types I-III) will be recruited over a 6-month period. Up to 6 video sessions of CVT-VT will be delivered by a CVT-P using a video link. The primary outcome will be a change in pre-/post-therapy scores of a self-reported patient questionnaire (Voice Handicap Index (VHI)). Secondary outcomes include changes in throat symptoms (Vocal Tract Discomfort Scale), acoustic/electroglottographic and auditory-perceptual measures of voice. Acceptability of the CVT-VT will be assessed prospectively, concurrently and retrospectively both quantitatively and qualitatively. Differences from SLT-VT will be assessed by performing a deductive thematic analysis of CVT-P transcripts of therapy sessions. CONCLUSION This feasibility study will provide important data to support whether to proceed with a randomised controlled pilot study focusing on the effectiveness of the intervention compared to standard SLT-VT. Progression criteria will be based on demonstrating a positive outcome in treatment, successful delivery of the pilot study protocol, acceptability to all stakeholders and satisfactory recruitment rates.

Abstract
PURPOSE This study aims to investigate the frequency and severity of vocal tract discomfort (VTD) symptoms and to determine the relationship between VTD and type of thyroidectomy, voice problem history, vocal abuse, and misuse behaviors, and the voice handicap index (VHI) in the thyroidectomy patients undergoing thyroidectomy, pre- and post-operatively pre- and post-thyroidectomy. MATERIALS The sample comprised 21 thyroidectomy patients undergoing thyroidectomy, including 10 patients with total thyroidectomy and 11 patients with partial thyroidectomy. The participants underwent videolaryngoscopy examination and completed the voice history questionnaire, the VTD scale, and the VHI, before and after the surgery. RESULTS Dryness was the most frequently occurring symptom, pre- and post-thyroidectomy. Participants with total thyroidectomy reported significantly higher frequency and severity of tickling than those in the preoperative status (p<.05). The frequency and severity of many VTD symptoms in the participants with voice problems and a vocal abuse and misuse history were higher than those without such a history at both assessment times (p<.05). There was significant correlation between the frequency and severity of VTD and VHI scores, pre-thyroidectomy pre-operatively (r = 0.488-0.575, p<.05). CONCLUSIONS An increment in the frequency and severity of tickling was reported by total thyroidectomy patients, post-thyroidectomy post-operatively. The type of thyroidectomy, voice problem history, and vocal abuse and misuse behaviors seem to influence the frequency and severity of VTD. Considering the correlation between VTD and VHI, the VTD scale provides important clinical information and can be used for evaluation and consultation purposes.

Abstract
Objective During COVID-19, government measures to prevent disease spread included advice to work from home. In addition to occupational risk factors, the increased use of telecommunication and changed work environment may contribute to voice and vocal tract discomfort (VTD). This study established the prevalence, incidence, characteristics and impact of self-perceived dysphonia and VTD in those working from home during COVID-19. Methods A cross-sectional, observational study using an online survey recruited 1575 participants. It captured information about dysphonia and VTD presence, onset, and severity. Those with dysphonia completed the voice-related quality of life to measure impact. Regression analyses identified risk factors for voice and vocal tract problems. Results Dysphonia and VTD prevalence rates were 33% and 68%, respectively, incidences were 28% and 50%. Perceived dysphonia severity was mild in 72% of cases. Dry throat was the most common VTD symptom at 66%. Mean voice-related quality of life score was 82.4 (standard deviation ± 13.2). Raising or straining the voice while working predicted new onset dysphonia and VTD. Increasing telecommunication use was associated with worse dysphonia and VTD onset. Conclusion Those working from home have seen a rise in dysphonia and VTD, which were associated with communication modality and change in environment. If home offices become the ‘new normal’ post-COVID, workplaces should consider voice training for employees to limit potential difficulties.

Abstract
Introduction The current Italian law does not include any guidance regarding voice education, prevention of voice disorders and screening in subjects with high vocal loading such as teachers. Objectives We aimed to check the correlation between the Vocal Tract Discomfort Scale (VTDS) with the Voice Symptom Scale (VoiSS) for the evaluation of Italian teachers. In addition, we aimed to investigate whether there are differences in the frequency and intensity of discomfort symptoms in teachers with disabilities comparing vocal tract discomfort symptoms in teachers with high risk (HRVD) and low risk (LRVD) of vocal disorders according to the VoiSS cutoff (> 15.5). Methods We analyzed 160 Italian teachers (111 women and 49 men) that completed the VTDS and VoiSS at vocal evaluation. The Spearman correlation test was applied to all variables. The Mann-Whitney U test was used to compare the average number of discomfort symptoms among HRVD and LRVD teachers. Results A moderate positive correlation was observed between the average number, frequency, and intensity of discomfort symptom and the total score, physical domain score, and limitation domain score of the VoiSS. Only the emotional domain score of the VoiSS showed a weak positive correlation ( p < 0.001). Teachers considered in the HRVD group according to the VoiSS score had a higher number, frequency, and intensity of vocal tract discomfort symptoms. Conclusion There is correlation between the VTDS and VoiSS scales. Like the VoiSS, the VTDS is a questionnaire that detects HRVD teachers. Therefore, the results suggest that both questionnaires could be useful for a preventive voice program for Italian teachers.

Abstract
OBJECTIVES The present study translated the Vocal Tract Discomfort Scale (VTDS) into Korean (K-VTDS) and evaluated its reliability and validity. STUDY DESIGN This was a prospective study. METHODS The VTDS was first translated into Korean and validated. One hundred and fifty-nine patients with voice disorders were divided into three different diagnostic groups (functional, structural, and neurologic voice disorder) and 131 vocally healthy adults were also included. All participants completed the K-VTDS and the Korean version of the Voice Handicap Index (K-VHI) and Korean versions of the Voice-Related Quality of Life (K-VRQOL). The internal consistency of the K-VTDS was analyzed through Cronbach's α coefficient. The VTDS score differences related to the diagnostic groups were assessed with t test and analysis of variance. We assessed the correlation between the K-VTDS, the K-VHI, and the K-VRQOL using Pearson's correlation analysis. RESULTS High internal consistency and the test-retest reliability of the K-VTDS were found. The voice disorder group had significantly higher K-VTDS scores for the subscales and total scores than those in the healthy group (P < 0.001). The K-VTDS scores for the subscale of frequency and total scores were highest in the functional voice disorder group. We found a significant difference in frequency and total score of the K-VTDS between the functional voice disorder group and the structural voice disorder group (P < 0.05). We observed a strong positive correlation among the scores for the subscales of frequency and severity, and total scores in the K-VTDS. The K-VTDS showed moderate correlation with the K-VHI and the K-VRQOL. CONCLUSION The K-VTDS is a reliable and valid instrument for voice assessment for voice disorders in Korean-speaking patients.

Abstract
OBJECTIVES To elaborate reduced versions of the Pediatric Vocal Symptoms Questionnaire (PVSQ) protocol for the two forms of application of the instrument: self-evaluation (SE) and parental evaluation (PE). METHODS The Brazilian validation database of the PVSQ was used (Zip code: 758,309). Data were collected from 716 people, comprising 367 children and adolescents and 349 parents/guardians with and without voice complaint and/or vocal alteration. Three major procedures were adopted: 1. Verification of suitability of the database; 2. Determination of the extraction technique and the number of factors to be extracted, and 3. Decision on the type of factor rotation. For factor analysis, the Kaiser rule and Varimax rotation were used; Spearman's correlation analysis was used to verify the degree of relationship between the PVSQ variables, both of the SE and PE. The Mann-Whitney test was used to analyze the ROC curve of the general score of vocal symptoms of each version. A 5% significance statistical level was adopted. RESULTS Factor analysis made it possible to elaborate four new versions of the PVSQ, called: "common core of the PVSQ" (SE and PE), "common core of the PVSQ reduced version" (SE and PE), "PVSQ SE reduced version" and "PVSQ PE reduced version". The most complete version of the PVSQ has 7 domains in the SE and 5 in the PE. The common core of the PVSQ SE reduced version had a better area under the ROC curve (AUC), efficiency and sensitivity, and the PVSQ PE reduced version had better specificity. CONCLUSIONS Four new reduced PVSQ versions are available, containing 10 to 26 items. Aspects of specificity, efficiency and sensitivity, as well as discriminating capacity should be considered in the choice of the version and is a prerogative of the clinician who applies the instrument. As the questionnaire allows the comparison between the parental evaluation and the self-evaluation, it is recommended to apply the same version for parents and children.
