Abstract
OBJECTIVE To analyze the efficacy of a modified approach to thyroplasty type one using prolene mesh implant. STUDY DESIGN Interventional study. PLACE AND DURATION OF STUDY Combined Military Hospital Kharian, Pakistan, in Ent department, from July 2020 to Jan 2021. METHODOLOGY Medialization thyroplasty with prolene mesh was performed on the patients satisfying the inclusion criteria. They were analyzed objectively as well as subjectively in terms of Mean Maximum phonation time, maximum word count, and visual analog score about the quality of voice. Data analysis was done with SPSS version 20. Pre-operative and post-operative records were compared using paired sample t-test. RESULTS A total of 39 patients underwent vocal cord medialization with prolene mesh implant. The Mean age for medialization was 41.09 + 13.37. 23 patients were females and 15 were males. 26 patients had unilateral and 13 patients had bilateral vocal dysfunction. 18 of them had vocal dysfunction due to thyroidectomy, eight had idiopathic causes and 13 had miscellaneous. The improvement in mean visual analog score was 2.87 postoperatively. Median maximum phonation time increased about five seconds postoperatively, seven seconds in males, and 4.5 seconds for females. The maximum word count increased from 11.33 preoperatively to 18.28 postoperatively. There were no major complications observed in our study. CONCLUSION These results were comparable to many other studies for vocal cord medialization with different implant materials. But prolene mesh implant offers an easily available yet cost-effective alternative with similar benefits. LEVEL OF EVIDENCE III (Treatment benefits: Non-randomized controlled cohort/follow-up study).

Abstract
PURPOSE Teachers are occupational voice users with significant vocal demand. This study examined if a vocal hygiene program could mitigate the effects of occupational vocal demand in primary school teachers across 1 month. METHOD Sixty female teachers participated, with 30 in an experimental group receiving vocal hygiene education plus daily home practice for 1 month and 30 in a control group with no intervention. Their vocal changes across the month were quantified with (a) acoustic measures on fundamental frequency (fo), vocal intensity, jitter and shimmer, harmonics-to-noise ratio, and smoothed cepstral peak prominence and (b) Voice Handicap Index (VHI-10) and Vocal Fatigue Index (VFI) scores. RESULTS Analysis of covariance showed significantly larger changes (significant decreases) in conversational fo and in jitter for the experimental group relative to the control group. Post hoc pairwise comparisons following repeated-measures analysis of variance showed significant decreases in conversational fo and in jitter across the month for the experimental group. No significant differences in VHI-10 and VFI scores were found between the groups. CONCLUSIONS Vocal demand-related changes in acoustic measures could be partially mitigated with the vocal hygiene program. Future studies with a more refined intervention program and more long-term follow-up are recommended to better understand the long-term benefits of vocal hygiene programs on primary school teachers.

A Scoping Review and Meta-Analysis. J Voice 2023:S0892-1997(22)00419-2. [PMID: 36737268 DOI: 10.1016/j.jvoice.2022.12.018] [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: 10/27/2022] [Revised: 12/20/2022] [Accepted: 12/21/2022] [Indexed: 02/05/2023]
Abstract
INTRODUCTION Vocal fatigue is a clinical manifestation associated with a perception of negative vocal adjustment. It is related to the increase in the sensation of excessive effort when speaking and the lack of conditioning of the muscles and structures that involve vocal production. Because it has a complex and multifactorial diagnosis, there is still no consensus on the symptoms most commonly found in this clinical condition. OBJECTIVE To review and analyze the symptoms that characterize the clinical condition of vocal fatigue. METHODS This study consists of a scoping review carried out in the Cochrane Library, Embase, Lilacs, and Medline databases. Observational studies or clinical trials from the last 10 years. Studies with participants younger than 18 years of age were excluded; as well as research that did not describe symptoms of vocal fatigue or that presented vocal fatigue as a symptom; studies with patients with neurological, psychiatric, syndromic conditions, or head and neck cancer. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies NHLBI-NIH scale was used to assess the methodological quality of selected observational studies and the PEDro scale for the analysis of experimental studies. The steps were performed by three blinded evaluators. Subsequently, meta-analyses of global means were executed for each factor under study; a comparison of the difference in the mean score for each factor between exposed and unexposed; a comparison of the difference in the average score, among non-professional voice users, for each factor between exposed and unexposed. RESULTS In the searches performed, 956 articles were found and 29 articles were selected according to the eligibility criteria. Of these, 93.11% of the studies were observational and 6.89% were clinical trials. Regarding the gender and age group of the study samples, women aged between 30 and 45 years were predominant. As for the occupational use of voice, 68.97% of the samples were composed of professional voice users and 31.03% of non-professional voice users, with most professional voice users being teachers and non-professional voice users, individuals with dysphonia or vocal complaint. To assess vocal fatigue symptoms, 28 studies used the Vocal Fatigue Index (VFI) protocol, and only one study used another assessment protocol, Self-Administered Voice Rating. All studies were classified as regular, according to the scale used. As for the meta-analyses performed, the mean scores of the VFI factors were higher among professional voice users when compared to non-professional voice users and higher in dysphonic individuals compared to non-dysphonic individuals. CONCLUSION The vocal fatigue symptoms found in this review were common in the populations of professional voice users and non-professional voice users and dysphonic and non-dysphonic individuals. These symptoms were related to vocal recovery after rest, physical discomfort, and restricted vocal use.

J Voice 2022:S0892-1997(22)00174-6. [PMID: 36137878 DOI: 10.1016/j.jvoice.2022.06.019] [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: 05/19/2022] [Revised: 06/14/2022] [Accepted: 06/14/2022] [Indexed: 10/14/2022]
Abstract
OBJECTIVES Pulmonary function is closely associated with voice quality especially in patients with voice disorder including unilateral vocal fold paralysis (UVFP). Injection laryngoplasty (IL) is the standard treatment for patients with UVFP. We investigated the subjective and objective voice outcomes according to pulmonary function test (PFT) before IL in patients with UVFP. METHOD We retrospectively analyzed the patients who underwent IL for UVFP between 2004 and 2021 (N = 1201), and finally investigated 261 patients with PFT results before IL. The patients were classified into three groups according to results of PFT: normal (n = 189, 72%), mild (n = 40, 15%), and moderate (n = 32, 13%) obstructive pattern. Aspiration symptoms and subjective and objective voice parameters of voice handicap index (VHI), GRBAS score, maximal phonation time (MPT), Jitter, Shimmer, and noise to harmonic ratio (NHR) were compared between normal and abnormal (mild or moderate obstructive pattern) PFT groups. RESULTS Age (68.0 ± 9.1 and 61.2 ± 12.6, respectively) was significantly higher and males were more common (84.7% and 57.7%, respectively) in abnormal PFT than in normal PFT. Aspiration showed significant improvement in all groups. The subjective and objective voice parameters significantly improved after IL in normal and mild obstruction groups, but MPT, Shimmer, and VHI did not significantly improve in the moderate obstruction group. The improvement in VHI-30 after IL was significantly higher in the normal group (20.0 ± 29.5) than in the mild (10.3 ± 32.8) or moderate (9.9 ± 33.2) obstruction group (P = 0.035). Improved amounts of MPT, Jitter, Shimmer, and NHR were not significantly different among the groups, but improvement of VHI was smallest in the moderate obstructive pattern group. CONCLUSION Voice parameters showed significant improvement after IL in both normal and mild obstructive pattern groups, but MPT and VHI did not significantly improve in the moderate obstructive pattern group. In addition, patients with normal pulmonary function had marked improvement of subjective symptoms after IL in comparison with patients with abnormal pulmonary function.

Abstract
Vocal fatigue has remained an elusive construct-despite its significant impact on communication, vocation, and quality of life. Current frameworks define vocal fatigue in the context of vocal demands and vocal demand-responses. However, the impact of factors like individuals' baseline vocal fitness and perception of the demand are not well understood. What is also not well understood are the effects of specific vocal demand ingredients on an individual's vocal demand responses. Furthermore, current outcome measures utilized to capture vocal fatigue lack sensitivity and underlying mechanisms are poorly understood. These gaps have led to inconclusive next steps in how to best define, assess, monitor, and manage vocal fatigue. A conceptual framework is needed to study and better understand vocal fatigue constructs. Such a framework should consider the individual's baseline physiology, psychology, key vocal demand ingredients, and biophysiological mechanisms underlying demand responses. The objective of this paper is to help the reader better understand the complex and heterogeneous nature of vocal fatigue and its impact on reliable assessment and monitoring. Future studies will require better elucidation of vocal demand ingredients, will need more sensitive vocal demand response measures, and will need to take in to account an individual's baseline physiology and psychological factors.

Abstract
Purpose Vocal exertion is common and often results in reduced respiratory and laryngeal efficiency. It is unknown, however, whether the respiratory kinematic and acoustic adjustments employed during vocal exertion differ between speakers reporting vocal fatigue and those who do not. This study compared respiratory kinematics and acoustic measures in individuals reporting low and high levels of vocal fatigue during a vocal exertion task. Methods Individuals reporting low (N = 20) and high (N = 10) vocal fatigue participated in a repeated measures design study over 2 days. On each day, participants completed a 10-minute vocal exertion task consisting of repeated, loud vowel productions at elevated F0 sustained for maximum phonation time. Respiratory kinematic and acoustic measures were analyzed on the 1st vowel production (T0), and the vowels produced 2 minutes (T2), 5 minutes (T5), 7 minutes (T7), and 10 minutes (T10) into the vocal exertion task. Vowel durations were also measured at each time point. Results No differences in respiratory kinematics were observed between low and high vocal fatigue groups at T0. As the vocal exertion task progressed (T2-T10), individuals reporting high vocal fatigue initiated phonation at lower lung volumes while individuals with low vocal fatigue initiated phonation at higher lung volumes. As the exertion task progressed, total lung volume excursion decreased in both groups. Differences in acoustic measures were observed, as individuals reporting high vocal fatigue produced softer, shorter vowels from T0 through T10. Conclusions Individuals reporting high vocal fatigue employed less efficient respiratory strategies during periods of increased vocal demand when compared with individuals reporting low vocal fatigue. Individuals reporting high vocal fatigue had shorter maximum phonation time on loud vowels. Further study should examine the potential screening value of loud maximum phonation time, as well as the clinical implications of the observed respiratory patterns for managing vocal fatigue.

Abstract
PURPOSE Despite the high prevalence of primary muscle tension dysphonia (MTD-1), its underlying mechanisms and their interrelationships have yet to be fully identified. The objectives of this integrative review were (a) to describe and classify the suggested underlying mechanisms for MTD-1, (b) to appraise the empirical evidence supporting each of the proposed mechanisms, and (c) to summarize the information in an integrative model. METHOD PubMed, Scopus, and CINAHL were searched for all publications pertaining to muscle tension dysphonia. Papers were retained if they included theoretical or empirical data pertaining to underlying mechanisms of MTD-1. A total of 921 papers initially qualified for screening, of which 100 remained for consideration in this review. Underlying mechanisms of MTD-1 were extracted using a consensus approach. RESULTS Seven broad categories of putative mechanisms involved in MTD-1 were identified: psychosocial, autonomic, sensorimotor, respiratory, postural, inflammatory, and neuromuscular. These categories were further divided into 19 subcategories detailed in the body of this review article. Based on the reviewed evidence, our proposed integrative model presents MTD-1 as an idiosyncratic motor adaptation to physiological perturbation or perceived threat. Under this model, physiologically or psychologically aversive stimuli can instigate a series of motor adaptations at multiple levels of the nervous system, ultimately disturbing muscle activation patterns and their biomechanical outcomes. Importantly, these adaptations appear to have the potential to become chronic even after threatening stimuli are withdrawn. CONCLUSIONS The proposed model highlights the importance of personalized rehabilitation in MTD-1 treatment. Limitations of the literature are discussed to provide guidance for future research aimed at improving our understanding of MTD-1. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.19586065.

Abstract
BACKGROUND Teachers have been found to have a higher than normal risk to develop voice disorders. One common symptom of voice problems among teachers is the report and occurrence of vocal fatigue, often associated with different individual, physical, environmental, and professional factors. AIM The aim of this study was to provide insight into the potential effect of sinus infections, laryngitis, colds, seasonal allergies, and reflux on reported vocal fatigue, as quantified by the Vocal Fatigue Index (VFI). METHOD An exploratory cross-sectional design was implemented via an online survey sent by email to teachers of kindergarten through 12th-grade in 31 states throughout the USA. RESULT The main result of this study was that teachers with self-reported reflux and seasonal allergies had statistically significant higher scores on VFI Factor 1 (performance), VFI Factor 2 (pain), and VFI Factor 3 (recovery) when compared to those without self-reported reflux and seasonal allergies. CONCLUSIONS It may be likely that an individuals' change in reported vocal fatigue over time may be also associated with health-related factors, such as reflux and seasonal allergies rather than just changes in voice production. These associated factors should be considered and potentially controlled for in future research and clinical practice surrounding teachers' experience of vocal fatigue.

Abstract
To increase the reliability and comparability of vocal loading studies, this paper proposes the use of a standardized approach with experiments that are [1] grounded on consistent definitions of terms related to vocal fatigue (vocal effort, vocal demand, and vocal demand response), and [2] designed to reduce uncertainty and increase repeatability. In the approach, a semi-automated vocal loading task that also increases efficiencies in collecting and preparing vocal samples for analysis was used to answer the following research question: To what extent is vocal effort and vocal demand response sensitive to changes in vocal demands (ie, noise only, noise plus duration)? Results indicate that the proposed protocol design consistently induced change in both vocal effort and vocal demand response, indicating vocal fatigue. The efficacy of future vocal loading studies would be improved by adopting a more consistent methodology for quantifying vocal fatigue, thus increasing interstudy comparability of results and conclusions.

Abstract
Purpose The purpose of this preliminary study was to identify a vocal task that could be used as a clinical indicator of the vocal aptitude or vocal fitness required for vocally demanding occupations in a manner similar to that of the anaerobic power tests commonly used in exercise science. Performance outcomes for vocal tasks that require rapid acceleration and high force production may be useful as an indirect indicator of muscle fiber complement and bioenergetic fitness of the larynx, an organ that is difficult to study directly. Method Sixteen women (age range: 19-24 years, M age = 22 years) were consented for participation and completed the following performance measures: forced vital capacity, three adapted vocal function tasks, and the horizontal sprint test. Results Using a within-participant correlational analyses, results indicated a positive relationship between the rate of the last second of a laryngeal diadochokinesis task that was produced at a high fundamental frequency/high sound level and anaerobic power. Forced vital capacity was not correlated with any of the vocal function tasks. Conclusions These preliminary results indicate that aspects of the laryngeal diadochokinesis task produced at a high fundamental frequency and high sound level may be useful as an ecologically valid measure of vocal power ability. Quantification of vocal power ability may be useful as a vocal fitness assessment or as an outcome measure for voice rehabilitation and habilitation for patients with vocally demanding jobs.

[PMID: 32680804 DOI: 10.1016/j.jvoice.2020.06.006] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 06/03/2020] [Accepted: 06/04/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND AND OBJECTIVE The effects of presbyphonia are compounded by the decline in respiratory function that occurs with age. Commonly recommended exercises to optimize the use of respiratory muscles during speech, such as diaphragmatic breathing, are unlikely to be intensive enough to induce respiratory changes and impact vocal function. The objective of this study was to assess the effect of adding a targeted intervention, respiratory muscle strength training, to voice exercises in a sample of patients with presbyphonia. METHODS/DESIGN In this prospective, randomized-controlled trial, 12 participants received either (1) vocal function exercises (VFE), (2) VFE combined with inspiratory muscle strength training (IMST), or (3) VFE combined with expiratory muscle strength training (EMST). Data collected prior to and following 4 weekly intervention sessions included respiratory measures (pulmonary function and respiratory muscle strength) and voice measures (videostroboscopy, acoustic, auditory-perceptual, aerodynamic, and self-assessment measures). RESULTS Participants who received IMST improved their voice quality during connected speech (smoothed cepstral peak prominence and ratings of overall voice quality) and their scores on the three self-assessment questionnaires with large to very large within-group effect sizes (|d| = 0.82-1.61). In addition, participants in the IMST group reduced their subglottal pressure with a large effect size (d = -0.92). Participants who received EMST improved their maximum expiratory strength and smoothed cepstral peak prominence with large effect sizes (d = 0.80 and 0.99, respectively) but had limited improvements in other outcomes. Participants who received only VFE decreased their amount of vocal fold bowing, improved their voice quality on a sustained vowel (amplitude perturbation quotient), and improved their Glottal Function Index score with large effect sizes (|d| = 0.74-1.00). CONCLUSION Preliminary data indicate that adding IMST to voice exercises may lead to the greatest benefits in patients with presbyphonia by promoting improved subglottal pressure control as well as increasing air available for phonation, resulting in improved self-assessment outcomes.

Abstract
Purpose The purpose of this document is threefold: (a) review the uses of the terms "vocal fatigue," "vocal effort," "vocal load," and "vocal loading" (as found in the literature) in order to track the occurrence and the related evolution of research; (b) present a "linguistically modeled" definition of the same from the review of literature on the terms; and (c) propose conceptualized definitions of the concepts. Method A comprehensive literature search was conducted using PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scientific Electronic Library Online. Four terms ("vocal fatigue," "vocal effort," "vocal load," and "vocal loading"), as well as possible variants, were included in the search, and their usages were compiled into conceptual definitions. Finally, a focus group of eight experts in the field (current authors) worked together to make conceptual connections and proposed consensus definitions. Results The occurrence and frequency of "vocal load," "vocal loading," "vocal effort," and "vocal fatigue" in the literature are presented, and summary definitions are developed. The results indicate that these terms appear to be often interchanged with blurred distinctions. Therefore, the focus group proposes the use of two new terms, "vocal demand" and "vocal demand response," in place of the terms "vocal load" and "vocal loading." We also propose standardized definitions for all four concepts. Conclusion Through a comprehensive literature search, the terms "vocal fatigue," "vocal effort," "vocal load," and "vocal loading" were explored, new terms were proposed, and standardized definitions were presented. Future work should refine these proposed definitions as research continues to address vocal health concerns.
