[PMID: 37366280 DOI: 10.1002/lary.30850] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 05/09/2023] [Accepted: 06/11/2023] [Indexed: 06/28/2023]
Abstract
OBJECTIVE Muscle tension dysphonia (MTD) is the most common functional voice disorder. Behavioral voice therapy is the front-line treatment for MTD, and laryngeal manual therapy may be a part of this treatment. The objective of this study was to investigate the effect of manual circumlaryngeal therapy (MCT) on acoustic markers of voice quality (jitter, shimmer, and harmonics-to-noise ratio) and vocal function (fundamental frequency) through a systematic review with meta-analysis. DATA SOURCES Four databases were searched from inception to December 2022, and a manual search was performed. REVIEW METHODS The PRISMA extension statement for reporting systematic reviews incorporating a meta-analysis of health care interventions was applied, and a random effects model was used for the meta-analyses. RESULTS We identified 6 eligible studies from 30 studies (without duplicates). The MCT approach was highly effective on acoustics with large effect sizes (Cohen's d > 0.8). Significant improvements were obtained in jitter in percent (mean difference of -.58; 95% CI -1.00 to 0.16), shimmer in percent (mean difference of -5.66; 95% CI -8.16 to 3.17), and harmonics-to-noise ratio in dB (mean difference of 4.65; 95% CI 1.90-7.41), with the latter two measurements continuing to be significantly improved by MCT when measurement variability is considered. CONCLUSION The efficacy of MCT for MTD was confirmed in most clinical studies by assessing jitter, shimmer, and harmonics-to-noise ratio related to voice quality. The effects of MCT on the fundamental frequency changes could not be verified. Further contributions of high-quality randomized control trials are needed to support evidence-based practice in laryngology. Laryngoscope, 134:18-26, 2024.

The Effect of Adding Cricothyroid Visor Maneuver to Voice Facilitating Techniques on Improving Voice in Individuals With Primary Muscle Tension Dysphonia: A Pilot Randomized Clinical Trial. J Voice 2023:S0892-1997(23)00317-X.

Abstract
OBJECTIVES The purpose of the present study was to examine the effect of adding a cricothyroid visor maneuver to conventional voice-facilitating techniques on voice quality and reported symptoms in patients with primary muscle tension dysphonia. METHODS This was a double-blind two parallel-group clinical trial in which 20 adult patients participated through convenience sampling. Participants were allocated to intervention (combined treatment) and control (conventional treatment) groups. The intervention was performed for both groups for five sessions, twice a week. The two groups were compared after the intervention for primary outcome measures including maximum phonation time, jitter, shimmer, harmonic-to-noise ratio, and consensus auditory-perceptual evaluation of voice, and for secondary outcome measures including the voice handicap index, the voice activity and participation profile, the voice-related pain scale, and the vocal tract discomfort scale. RESULTS Within-group primary outcome comparison showed that both groups showed significant improvement in maximum phonation time and consensus auditory-perceptual evaluation of voice indices after treatment. the between-group comparison showed that the maximum phonation time increased significantly in the intervention group after the treatment (P = 0.03) and the effect size was large (es = 1.05). within-group secondary outcome comparison showed that all indices improved significantly in both groups except for the voice-related pain scale frequency. The between-group comparison showed that except for voice-related pain scale frequency, the intervention group reported significantly more improvement in all other self-reporting indices with a large effect size. CONCLUSIONS The study showed that adding cricothyroid visor maneuver to conventional voice-facilitating techniques, compared to conventional treatment alone, resulted in a significant increase in maximum phonation time, reduction in pain and vocal tract discomfort, increase in activity and participation, and improvement in voice-handicapped index in primary muscle tension dysphonia patients. Therefore adding cricothyroid visor maneuver to other treatments can be an effective method in improving primary muscle tension dysphonia which needs more studies in the future.

[PMID: 34261583 DOI: 10.1016/j.jvoice.2021.05.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/17/2021] [Accepted: 05/18/2021] [Indexed: 11/30/2022]
Abstract
PURPOSE An eclectic voice therapy program includes sequenced and structured set of exercises combining direct and indirect intervention methods. Tailor-made exercise prescription with specific cultural adaptations are needed to provide a holistic change to voice quality.1 This study detailed the construction of an exercise prescription for participants with hyperfunctional voice disorder [HFVD] in the Indian context. METHOD The exercise program was developed based on literature related to vocal therapy approaches and delivery methods. Adaptations were introduced to a selected set of exercises. Five voice experts verified the exercises and their prescription for content and feasibility of use in the Indian context. Modification suggested by the experts were included for framing the final version of the exercise program. This structured therapy program was planned for 6 weeks (30 minutes duration/session offered individually twice per week, with a gap of two days between sessions in a week) with the goals to improve voice quality, flexibility, and endurance while speaking. Five participants with HFVD partook in the study for pilot testing. Stroboscopy, perceptual voice analysis, Dysphonia Severity Index (DSI) and Vocal Fatigue Index in Tamil (VFI-T) were used to report the therapy outcomes. Participants' report on the learning process and generalization of the program were documented. Wilcoxon-signed rank test was used to test the pre-post outcome measures. RESULTS An eclectic voice therapy program, i.e., Comprehensive Voice Habilitation Program [CVHP] was constructed and it included vocal hygiene instructions, warm-up & cool-down, easy onset, resonant voice, and carry over exercises. Participants completed the program in 14-18 sessions (over 7 to 9 weeks of therapy). All participants showed significant changes in vocal fold movement patterns, reduction in ventricular hyperadduction, overall grade of voice quality, DSI and VFI-T. Participants reported that pictorial illustrations, feedback, and monitoring sheets were useful in learning the exercises. CONCLUSION CVHP showed significant change in the voice-related outcome measures and was a viable program for treating HFVD.

Abstract
OBJECTIVES The purpose of this paper is to review seminal identity theories grounded in social psychology and one concept from voice science and explain how this group may point to identity factors facilitating or impeding voice habilitation and rehabilitation. METHODS Identity theories from the social psychology literature (Dramaturgical Theory, Self-Categorization Theory, Self-Determination Theory, Identity Negotiation Theory) and vocal congruence are described. Concepts are synthesized with voice science research to explore potential identity-behavior relations at play in voice habilitation and rehabilitation. RESULTS Applicable concepts from social psychology and voice science suggest identity-related processes by which a client may or may not develop a voice difference/disorder, seek intervention, and achieve goals in intervention. A bidirectional relationship between identity and behavior has been well-established in the social psychology literature. However, the relevance of vocal behavior has yet to be formally examined within this literature. Importantly, although connections between behavioral tendencies and voice disorders as well as the contribution of identity to gender-affirming voice treatment have been established in the voice science literature, the consideration of identity's possible role in voice habilitation and rehabilitation in cis gender individuals has thus far been scant. CONCLUSIONS Research into identity and voice habilitation and rehabilitation may help to improve voice intervention outcomes. A possible adjunct to human studies is agent-based modeling or other computational approaches to assess the myriad factors that may be relevant within this line of inquiry.

Abstract
INTRODUCTION The COVID-19 pandemic necessitated a rapid restructuring of the clinical management of voice and upper airway disorders by speech-language pathologists (SLPs). As in-person therapy sessions were suspended, voice-specialized SLPs across healthcare settings shifted to online teletherapy. In this survey study, we queried voice therapists on their experiences with and opinions regarding the adoption of teletherapy into routine clinical practice. METHODS Voice-specialized SLPs were recruited nationwide to complete an online survey which included questions about the usability of software and hardware, patient management, the effectiveness of therapy, overall satisfaction, and suggestions for improvement. RESULTS 48 participants completed the survey. The majority of respondents reported frequent technical difficulties and poor access to or understanding of appropriate equipment. Overall, participants endorsed better patient access, attendance, and compliance, as well as increased scheduling flexibility. While 95% of the respondents stated they would recommend teletherapy to another SLP, only 20% supported a shift to exclusively virtual sessions. Forty percent of respondents endorsed a hybrid model consisting of initial in-person sessions followed by virtual ones. DISCUSSION Incorporating teletherapy into clinical voice practice has, for the most part, followed Carl May's normalization process theory framework, in that clinicians have invested understanding, training, time and effort, and appraisal into its implementation. However, the unusually rapid pace of change necessitated by the pandemic has presented its own set of challenges. Given the inherent conveniences of virtual therapy, the online modality is likely here to stay. It is critical that we understand the facilitators and barriers to its successful adoption.

Effects of Laryngeal Manual Therapy on Primary Muscle Tension Dysphonia (MTD-1): Implications for MTD-1 Type. J Voice 2022:S0892-1997(22)00106-0. [PMID: 35963763 DOI: 10.1016/j.jvoice.2022.04.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 04/01/2022] [Accepted: 04/04/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The study investigated effects of laryngeal manual therapy on different types of primary muscle tension dysphonia (MTD-1). STUDY DESIGN Interventional pre-test post-test design. METHODS Thirty-two traditional Iranian singers (mean age of 36.75 ± 9.34 years.) diagnosed with MTD-1, 8 female and 24 male, and recruited by convenience sampling completed the study. MTD-1 was classified as Morrison and Rammage's types 1-5, based on standardized criteria (1993). Pre-post-treatment measures were based on visual ratings of the larynx, acoustic analyses, auditory-perceptual assessments of voice (Auditory-Perceptual Rating Instrument for Operatic Singing Voice: EAI Scale Form), and the Persian Singing Voice Handicap Index (P-SVHI), reported before and after 10 sessions of laryngeal manual therapy (LMT). RESULTS The most notable finding was that the number of cases with MTD-1 types 1 and 2 actually increased after treatment, while the number of cases with MTD-1 types 3, 4 and 5 decreased. The data suggested that MTD-1 types 3, 4, and 5 tended to convert to types 1 and 2 with LMT. Acoustic analyses showed a significant decrease in F0 (males only; P = 0.011), a sharp decrease in HNR from 23.26 dB to 14.74 dB (P = 0.000), and an increase in shimmer from 4.18% to 6.90 % while no appreciable change was found in jitter (P = 0.57). Mean P-SVHI score decreased significantly from 52.03 to 41.16 (P = 0.002) and EAI score increased from 4.41 to 6.31 (P = 0.000) after treatment. CONCLUSIONS The primary finding was that the distribution of MTD-1 type changed after treatment in many cases, converting from one to another type. Acoustic as well as glottal closure measures for several participants revealed closure insufficiency after treatment, unveiled as hyperfunction was unloaded with LMT. For those participants, complementary treatments aimed at reinforcement of laryngeal closure functions would be appropriate.

[PMID: 35446683 PMCID: PMC9559660 DOI: 10.1044/2022_jslhr-21-00575] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 12/14/2021] [Accepted: 01/12/2022] [Indexed: 05/26/2023]
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
OBJECTIVE The purpose of this study was to assess the effects of a novel manual therapy, the Cricothyroid visor maneuver (CVM) therapy, on acoustic, auditory perceptual and self-assessment ratings in Muscle tension dysphonia (MTD) patients. STUDY DESIGN This was a retrospective study of 6 clinical cases. MATERIALS AND METHOD The study comprised 6 Persian speakers with MTD (2 men and 4 women) and mean age 38.50 ± 5.32 years. All patients underwent therapy between April and June 2021. Therapy was provided in five 30-minute sessions. This study used of acoustic measurement including smoothed cepstral peak prominence (CPPs), Dysphonia Severity Index (DSI), self-assessment scales include vocal tract discomfort scale (VTD), voice related quality of life (V-RQOL) and Consensus Auditory- Perceptual Evaluation of Voice (CAPE-V) for auditory perceptual assessment in pre- and post-CVM sessions. RESULTS In the present study the CPPs and DSI increased while only CPPs significantly changed in pre and post therapy (P < 0.05). Also, having done the therapy the total severity of dysphonia (CAPE-V) and VTD significantly decreased (P < 0.05) and V-RQOL significantly increased (P < 0.05). CONCLUSIONS These results suggest that CVM can be an effective method for promote significant improvements in acoustic measurements, auditory perceptual and self-assessment scales in patients with MTD.

Effectiveness of Intensive Voice Therapy Versus Weekly Therapy for Muscle Tension Dysphonia: A Noninferiority Randomised Controlled Trial With Nested Focus Group. J Voice 2021; 37:466.e17-466.e34. [PMID: 33741236 DOI: 10.1016/j.jvoice.2021.02.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 02/03/2021] [Accepted: 02/09/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To investigate the noninferiority of intensive voice therapy and compare its effects with weekly voice therapy on multidimensional outcomes of voice and well-being, satisfaction, and attendance in people with muscle tension dysphonia (MTD). The study further aimed to explore clinician's perceptions of barriers and enablers to implementation of intensive therapy. STUDY DESIGN Noninferiority randomised controlled trial with nested focus group. METHODS Twenty adults with MTD were randomised to receive either weekly voice therapy (1 hour per week for 8 weeks) or intensive voice therapy (1 hour, 4 days per week for 2 weeks). Participants were assessed by a blinded assessor twice before treatment, once post treatment and once at 4 weeks follow up on the primary outcome measure VHI and a range of secondary auditory-perceptual, acoustic, and patient (i.e., VoiSS, satisfaction) and clinician reported outcome measures (i.e., AusTOMs, attendance rates). Five Speech Language Pathologists also participated in a focus group to explore barriers and enablers to implementing intensive therapy, with questions and analyses guided by the Theoretical Domains Framework. RESULTS While noninferiority for the primary outcome measure VHI was not confirmed, secondary outcome measures revealed comparable within group clinically important improvements for VoiSS and the AusTOMs, as well as selected acoustic and auditory-perceptual measures for both groups. A trend of more improvements being maintained in the intensive group was identified. Comparably high satisfaction and attendance was also found between groups. Clinicians reported more enablers than barriers to providing intensive therapy which included beliefs that it led to greater progression and consolidation of patient learning, was supported by the local context and was associated with positive emotions. Barriers related to difficulties with booking and scheduling and the belief that intensive therapy was not for all patients. CONCLUSIONS While the current study was likely underpowered to establish non-inferiority of intensive therapy, secondary outcomes suggested that intensive therapy may produce comparable benefits to voice, wellbeing, satisfaction and attendance compared to weekly therapy and may be a viable therapy option for individuals with MTD. When implementing intensive therapy, clinicians should consider patient's preferences and availability, as well as systems which allow for flexible booking and therapy provision for patients. Clear recommendations for future research including the use of a larger sample and telehealth are also provided.

Abstract
Purpose Dysphonia can be evaluated by both patient-reported quality of life instruments and objective acoustic and aerodynamic analyses. However, less is known about the association between the two metrics. The goal of this study was to perform a meta-analysis of the correlation of the Voice Handicap Index (VHI-30) with the following objective parameters: fundamental frequency, jitter, shimmer, harmonics to noise ratio, noise to harmonic ratio, maximum phonation time, and the Dysphonia Severity Index. Method A literature search was performed in the PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature databases. Inclusion criteria were subjects age 18 years and older with voice complaints and assessed by both VHI-30 and objective voice analysis. Results A literature search resulted in 1,297 unique articles, of which 310 underwent full-text review and 17 studies were included in quantitative analysis. Significant pooled correlation was observed for VHI-30 total with jitter (.301 [.177; .416]), shimmer (.255 [.162; .344]), noise to harmonic ratio (.200 [.111; .285]), maximum phonation time (-.227 [-.352; -.094]), and Dysphonia Severity Index (-.254[-.455; -.0286]). Significant correlations were observed in 4/7 objective parameters with the Physical subscale, 3/7 with the Functional subscale, and 2/7 with the Emotional subscale. All significant correlations were negligible (0-.3) or low (.3-.5). Conclusions Results from meta-analysis showed that correlations between objective voice parameters and the VHI-30 were negligible or low. Further study is needed to determine if correlations vary by patient demographics or specific pathology.
