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

Update on Clinical Characteristics of Upper Airway Dyspnea: A Mixed Methods Study. J Voice 2023:S0892-1997(23)00247-3. [PMID: 37673754 DOI: 10.1016/j.jvoice.2023.08.006] [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: 06/12/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 09/08/2023]
Abstract
OBJECTIVES Provide a mixed-methods update on clinical presentation of patients with upper airway dyspnea (UAD). STUDY DESIGN Prospective, multicenter, mixed-methods study. METHODS Data were collected from 30 patients presenting to two tertiary ENT clinics with a chief complaint of dyspnea. Exclusionary criteria included abnormal structural laryngeal findings, uncontrolled pulmonary disorders, and medical conditions affecting breathing. Objective data collected included laryngeal exam findings, patient-reported outcome measures and symptom questionnaires, medications, and psychological diagnoses. Patients were categorized into groups based on the chronic or episodic nature of their dyspnea symptoms for comparison. Qualitative data from these groups were collected and analyzed. RESULTS Laryngeal exams revealed the presence of supraglottic constriction at rest was 26.66% and with phonation 83.33%. Ninety-three percent of patients did not show inappropriate vocal fold motion or adduction. Significant correlations were found between Dyspnea Index (DI) scores and other subjective questionnaires including Voice Handicap Index-10 (r = 0.64, P value = 0.001), Eating Assessment Tool-10 (r = 0.50, P value = 0.004), Cough Severity Index (r = 0.47, P value = 0.008), Vocal Cord Dysfunction Questionnaire (r = 0.59, P value = 0.005), and Somatic Symptom Scale-8 (r = 0.41, P value = 0.021). However, no significant correlation was found between the State-Trait Anxiety Index and DI (r = 0.27, P value = 0.1353). Qualitative analyses identified similar, but non-identical themes for both chronic and episodic dyspnea. CONCLUSIONS Patients with symptoms of UAD also report other abnormal head and neck and global body symptoms. Most patients with complaints of UAD in this study did not have abnormal vocal fold movements on laryngoscopy. There were differences in qualitative analyses between the chronic and episodic dyspnea groups, but no differences in state or trait anxiety.

A Comparison of Voice Therapy Attendance Rates Between In-Person and Telepractice. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2023; 32:1154-1164. [PMID: 36958015 DOI: 10.1044/2022_ajslp-22-00113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 05/06/2023]
Abstract
PURPOSE This study sought to investigate whether a significant difference exists in attendance, cancellations, and no-shows between in-person therapy and telepractice. The authors hypothesized that telepractice no-show and cancellation rates would be less than in-person no-show and cancellation rates. METHOD This retrospective study manually reviewed and analyzed attendance, no-show, and cancellation data over a 3-month span of in-person-only visits (September 2019-November 2019) and a 3-month span of telepractice visits (September 2020-November 2020) conducted at the Emory Voice Center, a tertiary care practice in urban Atlanta, Georgia. Additionally, data were collected for each patient's full course of therapy outside of the 3-month windows and analyzed for attendance, no-show, and cancellation patterns. RESULTS Data from 521 patients were available for review from the selected time frame. In 2019 (in-person), 157 patients met inclusion criteria, and in 2020 (telepractice), 176 patients were included. Therapy initiation, therapy attendance, and no-show rates had significant increases in the telepractice year, and cancellations made greater than 24 hr before the appointments had a significant decrease in the telepractice year. Furthermore, the overall course of therapy showed significantly fewer missed appointments and more attended appointments in the telepractice year. CONCLUSIONS Patients participating in voice therapy via telepractice are more likely to initiate treatment and attend treatment and less likely to cancel sessions compared with patients receiving treatment in person. These data combined with extant data on telepractice treatment efficacy indicate that telepractice should be considered standard of care and offered to all patients seeking treatment, as it removes many reported barriers to treatment.

Assessing Candidacy for Conversation Training Therapy: The Role of Patient Perception. J Voice 2023:S0892-1997(23)00044-9. [PMID: 36907679 PMCID: PMC10492888 DOI: 10.1016/j.jvoice.2023.02.008] [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: 09/29/2022] [Revised: 02/07/2023] [Accepted: 02/07/2023] [Indexed: 03/12/2023]
Abstract
OBJECTIVE Voice therapy is the primary treatment modality for voice rehabilitation. Specific patient-ability factors beyond patient-characteristic factors (eg, disorder diagnosis, age, etc.), that influence individual patient responses to voice treatment remain largely unknown. The goal of the current study was to determine the relationship between patient-perceived improvements in both the sound and feel of voice during stimulability assessment and voice therapy outcomes. STUDY DESIGN Prospective Cohort study. METHODS This study was a single-arm, single-center, prospective study. Fifty patients with primary muscle tension dysphonia and benign vocal fold lesions were enrolled. Patients read the first four sentences of the Rainbow Passage and were asked if they experienced a change in the feel or sound of their voice following the stimulability prompt. Patients then completed four sessions of conversation training therapy (CTT) voice therapy and followed up one-week and three-months after their last therapy session, for a total of six time-points. Demographic data were collected at baseline, and voice handicap index 10 (VHI-10) scores were collected at each follow-up time-point. The primary exposure variables were CTT intervention and patient perception of voice change to stimulability probes. The primary outcome was change in VHI-10 score. RESULTS On average, VHI-10 scores improved for all participants following CTT treatment. All participants heard a change in the sound of voice with stimulability prompts. Descriptively, patients who reported a positive change in the feel of their voice after stimulability testing recovered faster (ie, experienced a sharper decline in VHI-10) compared to those who did not note a change in feel of voice during stimulability testing. However, the rate of change over time was not significantly different between groups. CONCLUSION Patient self-perception of a change in the sound and feel of voice in response to stimulability probes during initial evaluation is an important factor in treatment outcomes. Patients who perceive an improved feel of their voice production after stimulability probes may respond to voice therapy more quickly.

Effect of Behavioral Cough Suppression Therapy Delivered via Telehealth. J Voice 2022:S0892-1997(22)00367-8. [PMID: 36550001 DOI: 10.1016/j.jvoice.2022.11.015] [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: 08/30/2022] [Revised: 11/09/2022] [Accepted: 11/10/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVES/HYPOTHESIS Behavioral cough suppression therapy (BCST) has demonstrated up to 88% effectiveness at treating refractory chronic cough (RCC). With onset of the COVID-19 pandemic, along with many other medical services, BCST shifted to telehealth delivery. Our group hypothesized that BCST delivered via telemedicine by a specialized Speech-Language Pathologist would be comparable to previously reported response to treatment for in-person settings. STUDY DESIGN Retrospective review. METHODS An Emory IRB approved, retrospective review of electronic medical records was completed for RCC patients who received BCST via telehealth from March 2020 through January 2022 at Emory Voice Center. Patients were included in the study if they had a diagnosis of RCC, were referred for BCST, were seen for at least one therapy session in the telehealth setting, and provided Cough Severity Index (CSI) data pre and post-treatment. Patients were excluded if they had incomplete datasets, a known pulmonary condition, structural laryngeal disorders, smoking history, dysphagia, and ACE-inhibitor use. Change in CSI score pre- and post-treatment was calculated to determine treatment effect. Paired-samples t-tests were conducted to compare pre-and post-treatment CSI score change. RESULTS Fifty-one RCC patients were included in this study; 88% were female with an average age of 60 years (SD = 12.68). Post-treatment CSI scores were significantly lower than pretreatment CSI scores (P < 0.0001). These findings are comparable to historical documented CSI change achieved with in-person BCST. CONCLUSIONS This study provides preliminary evidence of the efficacy of BCST via telehealth for treating RCC. The findings of this study support the continued flexibility in speech-language pathology service delivery to include in-person and telehealth platforms for RCC beyond the COVID-19 pandemic.

Abstract
OBJECTIVES The benefits of mindfulness meditation are well documented. This study evaluated the immediate effects of mindfulness meditation (MM) on the voice and voice user. STUDY DESIGN Prospective experimental study. METHODS Participants: 19 vocally healthy (VH) individuals, and 26 individuals with common voice disorders (CVD; benign lesions and hyperfunctional muscle tension) deemed stimulable for voice therapy. Exclusionary criteria: prior training or regular meditation practice. Participants recorded speech samples before and after a 11.5-minute prerecorded session of MM. PRIMARY OUTCOMES phonatory aerodynamics and participants' self-reported experience of voice. SECONDARY OUTCOMES self-reported anxiety, vocal acoustics, speech breathing patterns, and auditory-perceptual outcomes. Baseline self-reported measures of voice (Voice Handicap Index-10 - VHI-10), breathing (Dyspnea Index - DI), stress (Perceived Stress Scale - PSS), and trait mindfulness (Cognitive and Mindfulness Scale - Revised, CAMS-R, Five Facet Mindfulness Questionnaire - FFMQ) were compared between groups. RESULTS At baseline, CVD had significantly higher VHI-10 (P< 0.001) and DI (P= 0.0014), and lower trait mindfulness (CAMS-R, P= 0.02). No difference between groups for PSS or FFMQ. Changes postMM: decreased CPP for all-voiced sentences for VH (P= 0.003), decreased mean SPL (P= 0.012) on sustained vowel for VH, increased mean phonatory airflow during sustained vowel for CVD (P = 0.012). VH demonstrated a decrease in CPP on the all-voice sentence, and CVD demonstrated an increase, resulting in a significant between group difference (P= 0.013). Participants reported improvements in voice, emotional and physical states. State anxiety decreased for both groups (= < 0.001). No other objective outcomes reached significance. CONCLUSIONS After a brief MM, participants experienced improvement in physical, emotional, and cognitive states, and in their perceptions of their voice. Results indicate that a brief, single session of MM may be beneficial for some, but not sufficient to override habitual voice and speech patterns. Given the benefits of MM, future work should evaluate MM in a standard voice therapy protocol.

Abstract
INTRODUCTION The primary self-assessment questionnaire used for patients with chronic cough is the Leicester Cough Questionnaire (LCQ). The LCQ is a validated questionnaire that ranges in total score from 3 to 21. While it is known that a higher score on the LCQ reflects a better quality of life, normative data have not been reported for this questionnaire. OBJECTIVE The purpose of this study was to determine normative LCQ scores on a healthy population without cough. METHODS The LCQ was distributed via electronic survey to the authors' universities, professional affiliation email lists, and personal contacts. Participants were included if they were at least 18, nonsmokers, and without abnormal cough, without pulmonary disease, and without neurological disease. Participants answered questions regarding age, gender, and race/ethnicity, and completed the 19 LCQ questions. RESULTS One hundred forty-three (118 women) LCQ responses were analyzed. Average participant age was 47 years (SD = 13) and 133 (93%) were Caucasian. The mean LCQ Total score was 20.23 (SD = 0.85) with scores ranging from 17.05 to 21. CONCLUSIONS This study determined the following LCQ scores should be considered normal threshold scores: Total score - 17.68, Physical domain - 5.36, Psychological domain - 5.81, and Social domain - 6.06. The findings of this study will assist clinicians in determining severity of cough impact on quality of life using the LCQ. Further research is needed to ensure more complete participant demographic representation.

Abstract
OBJECTIVE The purpose of this investigation was to assess clinician and patient feedback about voice therapy using a variably occluded face mask (VOFM) and to determine if voice therapy augmented via a VOFM would result in favorable changes in patient self-perceived handicap, as well as acoustic and aerodynamic measures. METHODS/DESIGN This pilot study used a prospective, pre-post single group design. Eleven patients with dysphonia due to primary muscle tension dysphonia (8) or benign vocal fold lesions (3) were recruited. Data collected included patient and clinician feedback of voice therapy using a VOFM, voice handicap index (VHI)-10, acoustic and aerodynamic measures. Data were collected before treatment (baseline) and 1-week post-therapy. Wilcoxon signed-rank tests were used to compare data pre- and post-therapy. RESULTS Statistically significant improvement was observed for the VHI-10 with a median delta of -7. Clinician feedback generally reported that patients liked the VOFM, using the VOFM within the first two sessions of therapy, and within less than 10 min of use. All clinicians ranked the conversation level of the hierarchy as the most effective level. Three themes emerged from the Therapy Feedback Form: the VOFM was a (1) "Facilitator for Sensation," (2) a "Physical Tool," and that there was (3) "No Program Needed" to use the VOFM in voice therapy. There was a statistically significant improvement in cepstral peak prominence (p = 0.0329) and cepstral spectral index of dysphonia (p = 0.0164) in sustained vowels. DISCUSSION This pilot study represents the first investigation into clinician and patient perceptions of using a VOFM. Reported measures via patient perception, as well as clinician perceptions, and some acoustic and aerodynamic measures showed that participants got better with VOFM voice therapy. Last, in general, both clinicians and patients liked utilizing a VOFM in voice therapy.

Characterizing postoperative physiologic swallow function following transoral robotic surgery for early stage tonsil, base of tongue, and unknown primary human papillomavirus-associated squamous cell carcinoma. Head Neck 2021; 43:1629-1640. [PMID: 33547716 PMCID: PMC8046724 DOI: 10.1002/hed.26632] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 12/23/2020] [Accepted: 01/21/2021] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Data objectively evaluating acute post-transoral robotic surgery (TORS) swallow function are limited. Our goal was to characterize and identify clinical variables that may impact swallow function components 3 weeks post-TORS. METHODS Retrospective cohort study. Pre/postoperative use of the Modified Barium Swallow Impairment Profile (MBSImP) and Penetration-Aspiration Scale (PAS) was completed on 125 of 139 TORS patients (2016-2019) with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma. Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scores were retrospectively calculated. Uni/multivariate analysis was performed. RESULTS Dysfunctional pre-TORS DIGEST scores were predictive of post-TORS dysphagia (p = 0.015). Pre-TORS MBSImP deficits in pharyngeal stripping wave, swallow initiation, and clearing pharyngeal residue correlated with airway invasion post-TORS based on PAS scores (p = 0.012, 0.027, 0.048, respectively). Multivariate analysis of DIGEST safety scores declined with older age (p = 0.044). Odds ratios (ORs) for objective swallow function components after TORS were better for unknown primary and tonsil primaries compared to base of tongue (BOT) (OR 0.35-0.91). CONCLUSIONS Preoperative impairments in specific MBSImP components, older patients, and BOT primaries may predict more extensive recovery in swallow function after TORS.

Abstract
PURPOSE The purpose of this study was to investigate the typical symptoms and medical management characteristics of adult patients with refractory chronic cough (RCC) who are referred to speech-language pathology (SLP) for behavioral cough suppression therapy (BCST) in order to estimate cost-effectiveness and efficiency of current practice patterns for this population. METHODS One hundred sixty-four (164) patients with RCC referred for BCST were surveyed. Patients completed an initial survey at BCST onset related to symptom pattern and prior treatment, including the Leicester Cough Questionnaire (LCQ). Every four to six weeks patients completed follow-up surveys to assess their response to BCST. RESULTS Mean age was 58 years (83.5% women). The majority of patients reported their cough began two or more years prior to BCST. Approximately half (49%) reported seeing four or more physicians (including primary care physicians) and being prescribed four or more medications (57%) prior to BCST. Medications targeting post-nasal drip (72%), reflux (70%), asthma (56%), and allergies (56%) were most commonly prescribed. BCST resulted in a clinically significant improvement in 70.1% of participants. The mean change in LCQ for those who improved with BCST was 6.61. Over half (58%) reported they were quite satisfied to completely satisfied with their treatment response. The average time from enrollment to study completion was 64 days. CONCLUSION The results of this study suggest early intervention with BCST may be a cost-effective and efficient option for patients with RCC.

Abstract
OBJECTIVES Presbyphonia negatively impacts quality of life in patients with age-related voice changes. A proof-of-concept study showed promise for high vocal intensity exercise to treat presbyphonia, which became the basis for a novel intervention for age-related voice changes known as Phonation Resistance Training Exercises (PhoRTE). Expiratory Muscle Strength Training (EMST) has also been proposed as an additional intervention to target and strengthen the aging respiratory system; however, EMST has undergone limited evaluation as an adjunct treatment for elderly patients undergoing voice therapy for presbyphonia. This study determined if the addition of EMST to PhoRTE voice therapy (PhoRTE + EMST) is at least as effective at voice improvement as PhoRTE alone. STUDY DESIGN Prospective, randomized, controlled, single-blinded, non-inferiority. MATERIALS AND METHODS Participants aged 55 years or older with a diagnosis of vocal fold atrophy were randomized to complete PhoRTE therapy or PhoRTE + EMST. The primary outcome was change in Voice Handicap Index-10 (VHI-10). Secondary outcomes included the Aging Voice Index, maximum expiratory pressure, and acoustic and aerodynamic measures of voice. Repeated measures linear mixed models were constructed to analyze outcomes at a significance level of α = 0.10. RESULTS Twenty-six participants were recruited for the study, and 24 participants were randomized to either treatment arm. Sixteen participants completed the entire study. Both treatment arms showed statistically significant and clinically meaningful improvements in VHI-10 (PhoRTE mean [M] = -8.20, P < 0.001; PhoRTE + EMST M = -9.58, P < 0.001), and PhoRTE + EMST was noninferior to PhoRTE alone (P = 0.069). Both groups experienced a statistically significant pre-post treatment decrease (improvement) in AVI scores (PhoRTE M = -18.40, P = 0.004; PhoRTE + EMST M = -16.28, P = 0.005). PhoRTE+EMST had statistically significantly greater changes in maximum expiratory pressure compared to PhoRTE alone (PhoRTE M = 8.24 cm H2O, PhoRTE + EMST M = 32.63 cm H2O; P= 0.015). Some secondary acoustic and aerodynamic outcomes displayed trends toward improvement. CONCLUSION This study demonstrates that voice therapy targeting high vocal intensity exercise (eg, PhoRTE) and EMST can play a role in improving voice outcomes for patients with presbyphonia.

Abstract
INTRODUCTION Legalization of cannabis consumption in the United States (U.S.) has increased rapidly, impacting consumption rates in the general U.S. POPULATION The objective of this survey study was to establish prevalence estimates of cannabis consumption among voice patients, in addition to characterizing patterns of cannabis consumption. METHODS A multicenter, anonymous survey study of cannabis consumption took place at multidisciplinary tertiary voice care clinics in Portland, Oregon (PDX) and Pittsburgh, Pennsylvania (PIT) between April 2017 and December 2018. A convenience sample of 300 consecutively enrolled English-speaking patients 21 years and older with a voice disorder completed the survey. Data were obtained on the prevalence of cannabis consumption, frequency and methods of cannabis consumption, in addition to health impacts and demographics. RESULTS Agresti-Coull prevalence proportion estimates for cannabis consumption were higher among voice patients in PDX compared to PIT. Current consumers in PDX and PIT showed a similar frequency of cannabis consumption. Combustion methods (eg, joint) were more popular than non-combustion methods (eg, vaping) among current consumers; inhaled methods (eg, joint) were more popular than non-inhaled methods (eg, edibles). Though vocal handicap scores for current consumers were similar across sites and comparable to lifetime non-consumers who also were non-smokers of tobacco, a lifetime history of cannabis consumption was associated with vocal and overall health impacts. CONCLUSIONS Prevalence estimates for current cannabis consumption among voice patients from tertiary voice care clinics mirrored prevalence estimates reported for large, representative samples from Oregon and Pennsylvania. These findings provide valuable insight on the extent of cannabis consumption among voice patients.

Abstract
Telemedicine-conveying medical information virtually for planning, diagnosis, or treatment-has been a part of the American medical system for over 100 years. A constantly evolving modality, telepractice was a supplemental care delivery system for most speech-language pathologists (SLPs) until March 2020 when the COVID-19 pandemic forced clinical operations to halt in-person activities and convert as much as possible to virtual platforms. The purpose of this article is to provide an overview of the need for telepractice prior to and beyond the current pandemic, the efficacy of telepractice for the voice-specialized SLP, limitations of telepractice, and best practices for providing care over telepractice with a specific focus on voice disorder diagnosis and treatment.

Abstract
This article introduces a novel approach to voice therapy called conversation training therapy (CTT). CTT is the first voice therapy approach to remove the therapeutic hierarchy common in most treatment programs. Rather, CTT uses patient-driven conversation as the sole stimuli in therapy to increase perceptual awareness of voice production in conversational speech. The genesis as to why CTT was developed, as well as the conceptual, theoretical, and component parts of CTT, will be explained. In addition, this article will offer examples of the language of therapy, as it applies to CTT and how to trouble-shoot if problems arise. Medical documentation relevant to CTT will also be outlined. Last, results from a recent efficacy study on CTT will be reported.

Phonation With a Variably Occluded Facemask: Effects of Task Duration. J Voice 2020; 36:183-193. [PMID: 32586639 DOI: 10.1016/j.jvoice.2020.05.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 05/01/2020] [Accepted: 05/04/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVE Semioccluded vocal tract (SOVT) exercises are routinely included in many voice therapy programs because they have been shown to improve acoustic, aerodynamic, and patient-reported voice outcomes. One limitation of the traditional SOVT exercise is that the nature of phonation through straws or semioccluded oral postures allows only for single phoneme production. A variably occluded facemask (VOFM) allows for use of articulated connected speech beyond the production of single phonemes, while still providing occlusion and, presumably, the vocal efficiency benefits that arise from it. This study reports on the effect of time duration of phonation with a variably occluded facemask on voice outcomes in patients with voice disorders. DESIGN Prospective, randomized cohort study. METHODS Fifteen patients with voice disorders phonated for 5 minutes through a VOFM with diameter openings of 3.2, 6.4, and 9.6 mm. Acoustic and aerodynamic voice measures were collected before and after each occlusion trial. These results were compared to a historical patient group that received the same phonation training for 2 minutes. RESULTS Positive effect sizes were found for acoustic and aerodynamic improvements for all patients for at least one occlusion diameter. Effect sizes for aerodynamic outcomes were greater in the 5-minute conditions for both the 9.6- and 6.4-mm occlusions than the 2-minute condition. Effect sizes for acoustic outcomes were greater in the 5 minute than 2-minute trial for the 9.6- and 6.4-mm occlusion diameter, but greater in the 2 minute than 5-minute trial for 3.2-mm diameter. DISCUSSION This study provides evidence that all three occlusion sizes may elicit beneficial changes for different patients; however, 5 minutes of phonation into a facemask with end occlusion of 6.4-mm diameter results in improved acoustic and aerodynamic voice outcomes for many patients with voice disorders. Future studies should further explore phonatory physiologic changes of the VOFM in a larger sample of patients and translate effects into clinical treatment for patients with voice disorders.

Abstract
The emergence of the novel coronavirus disease 2019 (COVID-19) and the subsequent need for physical distancing have necessitated a swift change in health care delivery. Prior to the COVID-19 outbreak, many institutions utilized an interdisciplinary clinic model including both a laryngologist and a speech-language pathologist for the evaluation of patients with voice, swallowing, and upper airway disorders. To improve access, many providers are pursuing the use of interdisciplinary telemedicine to provide individualized patient-centered care while allowing for physical distancing. The purpose of this commentary is to review the current literature regarding telemedicine in laryngology and speech-language pathology as well as the current and future states of practice for interdisciplinary tele-evaluations.

Efficacy of Conversation Training Therapy for Patients With Benign Vocal Fold Lesions and Muscle Tension Dysphonia Compared to Historical Matched Control Patients. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2019; 62:4062-4079. [PMID: 31619107 PMCID: PMC7203518 DOI: 10.1044/2019_jslhr-s-19-0136] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 07/08/2019] [Accepted: 08/08/2019] [Indexed: 05/22/2023]
Abstract
Purpose Conversation training therapy (CTT) is the 1st voice therapy approach to eliminate the traditional therapeutic hierarchy and use patient-driven conversation as the sole therapeutic stimulus. The purpose of this investigation was to determine the efficacy of CTT compared to standard-of-care voice therapy approaches for the treatment of patients with voice disorders. Method A prospective study of CTT treatment outcomes in adults with dysphonia due to primary muscle tension dysphonia or benign vocal fold lesions compared to age, gender, and diagnosis historical matched control (HMC) patients was used. The primary outcome was change in Voice Handicap Index-10 (VHI-10); secondary outcomes included acoustic, aerodynamic, and auditory-perceptual outcomes. Data were collected before treatment (baseline), at the start of each therapy session, 1 week after the final therapy session (short-term follow-up), and 3 months after the final therapy session (long-term follow-up). Results For the CTT group, statistically significant improvements were observed for VHI-10. Though statistically significant improvements were observed for the VHI-10 for the HMC group, the CTT group saw significantly greater improvement in VHI-10. Furthermore, equivalent gains were observed following only 2 sessions of CTT compared to 4-8 sessions of traditional therapy. Significant improvements in the CTT group were observed for cepstral peak prominence in a vowel, fundamental frequency, Cepstral Spectral Index of Dysphonia in a vowel and connected speech, vocal intensity, average airflow in speech in a reading passage, number of breaths and duration of reading passage, and auditory-perceptual measurement of overall voice severity. Conclusions Results support the hypothesis that training voice techniques in the context of spontaneous conversational speech improves patient perception of voice handicap and acoustic, aerodynamic, and auditory-perceptual voice outcomes both immediately following treatment and at long-term follow-up. CTT participants also demonstrated significantly larger decreases in VHI-10 compared to HMC participants who received standard-of-care, nonconversational, hierarchical-based voice therapy.

Abstract
OBJECTIVES/HYPOTHESIS The incidence of cognitive impairment (CI) in the elderly general population is 10% to 20%. The incidence of CI in the elderly laryngology treatment-seeking population is unknown, and CI may impact decision making for elective medical/surgical treatment and negatively impact the outcome of voice/swallowing therapy. We sought to determine the prevalence of CI in elderly patients who are seeking laryngology care and to evaluate the feasibility of administering a cognitive screening instrument. STUDY DESIGN Prospective, Cross-sectional. METHODS One hundred fifty patients (≥65 years old) without a previous diagnosis of CI, seeking laryngology evaluation, were administered the Montreal Cognitive Assessment (MoCA) test by a trained physician. Other members of the clinical team were blinded to the MoCA results. RESULTS Twenty-five percent of participants obtained a score diagnostic for at least mild CI. The results showed a correlation between the MoCA scores and 1) the time needed to complete the test, 2) participant age, and 3) participant education level. No differences were observed between gender, alcohol consumption, or use of medications that can affect cognition and MoCA score. CONCLUSION One in four elderly laryngology treatment-seeking patients were found to have undiagnosed CI. This finding warrants consideration for CI screening for these patients being evaluated for voice therapy and elective surgery. Treatment decision making in this population may benefit from additional family involvement. LEVEL OF EVIDENCE 2c Laryngoscope, 130: 2003-2007, 2020.

Abstract
OBJECTIVES Goals of the current study were to (1) conduct initial validation of a new Paradoxical Vocal Fold Movement Disorder Screening Questionnaire (PVFMD-SQ); (2) determine if symptom-based questionnaires can discriminate between patients with confirmed PVFMD and those with diagnosed uncontrolled asthma without clinical suspicion for PVFMD; and (3) determine if a new questionnaire with diagnostic specificity could be created from a combination of significant items on previously validated questionnaires. METHODS This is a prospective, case-controlled study of patients with PVFMD only and asthma only, who completed five questionnaires: Dyspnea Index, Reflux Symptom Index, Voice Handicap Index-10, Sino-Nasal Questionnaire, and PVFMD-SQ. Factor analysis was completed on the new PVFMD-SQ, and the discrimination ability of selected factors was assessed by receiver operating characteristics curve. The factor with the greatest discriminatory ability was selected to create one diagnostic questionnaire, and scores for each participant were calculated to estimate how well the factor correlated with a PVFMD or asthma diagnosis. Mean scores on all questionnaires were compared to test their discriminatory ability. RESULTS Patients with PVFMD showed greater voice handicap and reflux symptoms than patients with asthma. A 15-item one-factor questionnaire was developed from the original PVFMD-SQ, with a sensitivity of 89% and specificity of 73% for diagnosing asthma versus PVFMD. The combined questionnaires resulted in four factors, none of which showed discriminatory ability between PVFMD and asthma. CONCLUSION This study represents the first time that a patient symptom-based screening tool has shown diagnostic sensitivity to differentiate PVFMD from asthma in a cohort of symptomatic patients.

Abstract
OBJECTIVES/HYPOTHESIS Benign midmembranous vocal fold lesions (BMVFLs) are common voice disorders, but interpretation of outcomes following treatment is difficult due to the lack of a standardized nomenclature system for these lesions. Outcome results are increasingly important to third party payers. This study aimed to investigate the outcomes of patients with BMVFLs using a previously validated nomenclature, and to provide incidences and outcome results for each diagnosis. METHODS A retrospective chart review of BMVFL patients was performed. Treatment was individualized but typically involved implementation of nonsurgical therapy followed by phonomicrosurgery as needed. A previously reported BMVFL stratification system was used. RESULTS A total of 224 patients with BMVFLs were studied. Sixty-seven percent of all patients with a BMVFL underwent phonomicrosurgery. The most common BMVFL types were polyp and nonspecific vocal fold lesion. Pseudocyst represented 0.9% of the cohort. The Voice Handicap Index-10 (VHI-10) and acoustic data demonstrate a high degree of treatment success. The mean change in VHI-10 was greatest for cyst-subepithelial and polyp. Fibrous mass-ligamentous patients had the smallest mean change in VHI-10. Mean post-treatment VHI-10 scores of all the lesions except fibrous mass-ligamentous were within normal limits (<11). CONCLUSIONS This study represents the first outcomes-based report of BMVFLs using a strictly defined nomenclature system for stratification of lesions. Ligamentous fibrous mass lesions have a decreased response to treatment compared to all other lesions. This study demonstrates the ability to return most BMVFL patients to normal speaking voice capabilities following treatment. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVES/HYPOTHESIS 1) Present phonatory aerodynamic data for healthy controls (HCs) in connected speech; 2) contrast these findings between HCs and patients with nontreated unilateral vocal fold paralysis (UVFP); 3) present pre- and post-vocal fold augmentation outcomes for patients with UVFP; 4) contrast data from patients with post-operative laryngeal augmentation to HCs. STUDY DESIGN Retrospective, single-blinded. METHODS For phase I, 20 HC participants were recruited. For phase II, 20 patients with UVFP were age- and gender-matched to the 20 HC participants used in phase I. For phase III, 20 patients with UVFP represented a pre- and posttreatment cohort. For phase IV, 20 of the HC participants from phase I and 20 of the postoperative UVFP patients from phase III were used for direct comparison. Aerodynamic measures captured from a sample of the Rainbow Passage included: number of breaths, mean phonatory airflow rate, total duration of passage, inspiratory airflow duration, and expiratory airflow duration. The VHI-10 was also obtained pre- and postoperative laryngeal augmentation. RESULTS All phonatory aerodynamic measures were significantly increased in patients with preoperative UVFP than the HC group. Patients with laryngeal augmentation took significantly less breaths, had less mean phonatory airflow rate during voicing, and had shorter inspiratory airflow duration than the preoperative UVFP group. None of the postoperative measures returned to HC values. Significant improvement in the Voice Handicap Index-10 scores postlaryngeal augmentation was also found. CONCLUSIONS Methodology described in this study improves upon existing aerodynamic voice assessment by capturing characteristics germane to UVFP patient complaints and measuring change before and after laryngeal augmentation in connected speech.

Abstract
PURPOSE The larynx has a dual role in the regulation of gas flow into and out of the lungs while also establishing resistance required for vocal fold vibration. This study assessed reciprocal relations between phonatory functions-specifically, phonatory laryngeal airway resistance (Rlaw)-and respiratory homeostasis during states of ventilatory gas perturbations. METHOD Twenty-four healthy women performed phonatory tasks while exposed to induced hypercapnia (high CO2), hypocapnia (low CO2), and normal breathing (eupnea). Effects of gas perturbations on Rlaw were investigated as were the reciprocal effects of Rlaw modulations on respiratory homeostasis. RESULTS Rlaw remained stable despite manipulations of inspired gas concentrations. In contrast, end-tidal CO2 levels increased significantly during all phonatory tasks. Thus, for the conditions tested, Rlaw did not adjust to accommodate ventilatory needs as predicted. Rather, stable Rlaw was spontaneously accomplished at the cost of those needs. CONCLUSIONS Findings provide support for a theory of regulation wherein Rlaw may be a control parameter in phonation. Results also provide insight into the influence of phonation on respiration. The work sets the foundation for future studies on laryngeal function during phonation in individuals with lower airway disease and other patient populations.

Abstract
Vagal nerve stimulators (VNS) are implanted to treat medically refractory epilepsy and depression. The VNS stimulates the vagus nerve in the left neck. Laryngeal side effects are common and include dysphagia, dysphonia, and dyspnea. The current case study represents a patient with severe dyspnea and dysphonia, persisting even with VNS deactivation. The case demonstrates the use of voice and respiratory retraining therapy for the treatment of VNS-induced dysphonia and dyspnea. It also highlights the importance of a multidisciplinary approach, including laryngology, neurology, and speech-language pathology, in the treatment of these challenging patients.

Abstract
PURPOSE In this study, the authors aimed to (a) determine whether phonatory airflows and estimated subglottal pressures (est-Psub) for women with primary muscle tension dysphonia/aphonia (MTD/A) differ from those for healthy speakers; (b) identify different aerodynamic profile patterns within the MTD/A subject group; and (c) determine whether results suggest new understanding of pathogenesis in MTD/A. METHOD Retrospective review of aerodynamic data collected from 90 women at the time of primary MTD/A diagnosis. RESULTS Aerodynamic profiles were significantly different for women with MTD/A as compared with healthy speakers. Five distinct profiles were identified: (a) normal flow, normal est-Psub; (b) high flow, high est-Psub; (c) low flow, normal est-Psub; (d) normal flow, high est-Psub; and (e) high flow, normal est-Psub. CONCLUSIONS This study is the first to identify distinct subgroups of aerodynamic profiles in women with MTD/A and to quantitatively identify a clinical phenomenon sometimes described in association with it-"breath holding"-that is shown by low airflow with normal est-Psub. Results were consistent with clinical claims that diverse respiratory and laryngeal functions may underlie phonatory patterns associated with MTD/A. One potential mechanism, based in psychobiological theory, is introduced to explain some of the variability in aerodynamic profiles of women with MTD/A.

Abstract
INTRODUCTION The purpose of this paper is to review the literature on the behavioral treatment of voice disorders in teachers. The focus is on phonogenic disorders, that is voice disorders thought to be caused by voice use. METHODS Review of the literature and commentary. RESULTS The review exposes distinct holes in the literature on the treatment of voice problems in teachers. However, emerging trends in treatment are noted. For example, most studies identified for review implemented a multiple-therapy approach in a group setting, in contrast to only a few studies that assessed a single-therapy approach with individual patients. Although the review reveals that the evidence around behavioral treatment of voice disorders in teachers is mixed, a growing body of data provides some indicators on how effectively rehabilitation of teachers with phonogenic voice problems might be approached. Specifically, voice amplification demonstrates promise as a beneficial type of indirect therapy and vocal function exercises as well as resonant voice therapy show possible benefits as direct therapies. Finally, only a few studies identified even remotely begin to meet guidelines of the Consolidated Standards of Reporting Trials statement, a finding that emphasizes the need to increase the number of investigations that adhere to strict research standards. CONCLUSIONS Although data on the treatment of voice problems in teachers are still limited in the literature, emerging trends are noted. The accumulation of sufficient studies will ultimately provide useful evidence about this societally important issue.
