Voice Therapy for Benign Voice Disorders in the Elderly: A Randomized Controlled Trial Comparing Telepractice and Conventional Face-to-Face Therapy

Efficacy of Voice Therapy With Acapella Choice ® Device in Subjects With Vocal Fatigue Delivered Via Telepractice

PURPOSE

The present study aimed at assessing the effectiveness of remote voice therapy (telepractice) implemented with Acapella Choice device in subjects with vocal fatigue.

METHODS

Thirty participants with vocal fatigue were randomly assigned to one of two treatment groups: (1) voice treatment with acapella Choice device plus vocal hygiene program (n=15), and (2) voice treatment with Water resistance therapy plus vocal hygiene program (n=15). Laryngoscopic assessment was conducted in all subjects to confirm diagnosis. Before and after voice therapy, participants underwent self-assessment of voice. Vocal Fatigue Index (VFI), Voice Handicap Index (VHI), and Vocal tract discomfort scale (VTDS) were used. Treatment period included six voice therapy sessions within 3 weeks, with a frequency of two therapy sessions per week. Each session lasted 30 minutes. For both groups, exercises consisted of a sequence of nine phonatory tasks performed with Acapella Choice (experimental group) and WRT (control group). Comparison for all variables were performed between experimental group and control group.

RESULTS

Significant improvements were found when comparing Pre and Post measures for both groups. No significant differences were found when comparing Acapella Choice group and WRT group.

CONCLUSION

Remote physiologic voice therapy with Acapella Choice device and water resistance therapy seem to be both effective to improve voice in subjects diagnosed with vocal fatigue. No differences should be expected between these therapeutic protocols when treating patients with vocal fatigue. Moreover, both are effective at reducing tiredness of voice, voice avoidance, physical discomfort associated with voicing, subjective perception of sensory discomfort in throat, and reduction of physical, emotional, and functional impact of voice problems.

How a Dysphonia App Can Promote the Motivation of Speech Therapists and Patients in the Long Term-A Qualitative Study in the LAOLA Project

OBJECTIVE

The care of patients with dysphonia will change due to the growing shortage of specialists, demographic change, and digitalization. To counteract the associated problems in patient care, the LAOLA app demonstrator is to be developed. In the future, patients will receive exercise videos for their training from their treating speech and language pathologist (SLP) via LAOLA. During the training, they will receive real-time biofeedback on visual (eg, posture) and auditory (eg, volume) criteria using machine learning. This study aimed to analyze the needs and requirements of SLPs and patients with dysphonia for an innovative mobile health application. It was determined how LAOLA can motivate regular training and what other functions are desired.

MATERIALS AND METHODS

An online survey (19 SLPs), a guideline-based focus group (10 SLPs), a reflection session (five SLPs), and individual interviews with six patients with dysphonia took place, which were evaluated according to the qualitative content analysis according to Kuckartz and Rädiker, which structured the content.

RESULTS

Of the seven main categories and (up to seven each) subcategories, the main category "LAOLA components regarding the training part" was the most revealing. The results were presented using the Technology Acceptance Model 2. From the user's point of view, LAOLA is innovative as a digital assistance system and would be used in everyday life. Maintaining motivation is just as important as avoiding control and pressure to perform. It is also important that LAOLA is not intended to replace treatment, but to complement it. Various specific functions, for example, an overview of services, were requested. The results are an important basis for the user-oriented development of the app.

CONCLUSION

Digitization creates new treatment options and enables individual patients to control their health more closely. LAOLA is intended to allow better monitoring of dysphonia and cost reduction in the healthcare sector, with data protection having a high priority. Since the smartphone is usually always present, voice training can be reminded at any time.

Navigating Through Innovation in Elderly's Health: A Scoping Review of Digital Health Interventions

Objectives

Comprehensively map and summarize digital health initiatives for the elderly and caregivers.

Methods

Scoping review between April and May 2022 based on Joanna Briggs methodology. Databases used included PubMed, Cochrane Library, CINAHL Plus, and Web of Science, along with grey literature and hand searches. Two reviewers independently conducted screening and eligibility phases, with a third resolving disagreements. Data were thematically analyzed.

Results

The review included 421 documents. Most documents were published between 2013 and 2022, with a recent increase. Most studies, originating from high-income countries, focused on home applications and were mainly in the testing and validation stages. Telephones and computers were the predominant devices. Health objectives included monitoring, prevention, and treatment, with interventions utilizing directed communication and personal health monitoring for individuals, and telemedicine and decision support for healthcare providers.

Conclusion

Increasing integration of technology in older adults' lives, along with their increasing proficiency, is driving a significant rise in digital health interventions. Despite this growth, further research in middle- and low-income countries, for caregivers and evaluating effectiveness and feasibility of these technological interventions is needed.

Voice Telerehabilitation in Iatrogenic Unilateral Vocal Fold Paralysis: From Necessity to Opportunity in the COVID-19 Time

OBJECTIVE

To evaluate results of telerehabilitation (TR) during the coronavirus disease 2019 pandemic for the treatment of dysphonia caused by permanent post-thyroidectomy unilateral vocal fold paralysis (UVFP).

METHODS

Forty subjects with post-thyroidectomy UVFP (onset <1 month) underwent TR. Videostrobolaryngoscopy, acoustic and perceptual voice analysis and patient self-assessment were carried out in person before, at the end of TR and 6 months later.

RESULTS

Twenty-five subjects spontaneously recovered full vocal fold motility at some time during follow-up, whereas 15 had a permanent UVFP at the end of the follow-up period. These subjects constituted our study group. At the early posttherapy control 10/15 subjects (66.6%) showed a complete glottal closure, while in 5/15 (33.3%) a glottal gap remained (P = 0.03). These results did not change 6 months after TR. At the late posttherapy control the maximum phonation time improved significantly (P = 0.02). Both post-therapy Voice Handicap Index scores were significantly lower than the pre-therapy ones (P = 0.04). Grade, Breathiness, and Asthenia parameters of the Grade-Roughness-Breathiness-Asthenia-Strain scale improved 6 months after TR (P < 0.05). The number of voice signals suitable for acoustic analysis increased significantly after therapy. Finally, 87% of patients were satisfied with TR.

CONCLUSIONS

With careful patient selection, TR may be considered as a promising method for voice therapy in postthyroidectomy UVFP.

Feasibility of Intensive Voice Therapy for Pediatric Vocal Fold Nodules Delivered via Telepractice: Pilot Study

PURPOSE

The aim of this study is to assess the feasibility of an intensive voice therapy delivered via telepractice for pediatric vocal fold nodules (VFNs).

METHOD

Ten children with VFNs (mean age = 6 years, range = 5-8 years) were recruited in this study. Assessments including stroboscopic ratings, acoustic parameters, aerodynamic and auditory perceptual measures, and parent-reported Pediatric Voice Handicap Index were administered pretreatment and within 1 week post treatment. Eight resonant voice therapy sessions were provided three times a week via a secure online platform, which were completed within 3 weeks. The assessments were conducted in a clinical face-to-face modality in China, whereas the therapy sessions were all conducted online, with the participants and their caregivers in China and the speech-language pathologist in Taiwan.

RESULTS

All participants completed the therapy sessions as scheduled, and there were no dropouts. Statistical analyses showed that significant improvements in acoustic and aerodynamic parameters, as well as stroboscopic and auditory-perceptual ratings.

CONCLUSION

This study provides positive preliminary results indicating intensive voice therapy delivered via telepractice may be feasible and effective for the pediatric VFN population. Service providers and families may consider this delivery modality for ease of access when voice therapy is recommended.

Telehealth versus face-to-face delivery of speech language pathology services: A systematic review and meta-analysis

BACKGROUND

There is an increasing demand for the provision of speech language pathology (SLP) services via telehealth. Therefore, we systematically reviewed randomized controlled trials comparing telehealth to face-to-face provision of SLP services.

METHODS

We searched Medline, Embase and Cochrane, clinical trial registries, and conducted a citation analysis to identify trials. We included randomized trials comparing similar care delivered live via telehealth (phone or video), to face-to-face. Primary outcomes included: % syllables stuttered (%SS) (for individuals who stutter); change in sound pressure levels monologue (for individuals with Parkinson's disease); and key function scores (for other areas). Where data were sufficient, mean differences were calculated.

RESULTS

Nine randomized controlled trials were included; eight evaluated video and one evaluated phone telehealth. Risk of bias was generally low or unclear, excepting blinding. There were no significant differences at any time-point up to 18 months for %SS (mean difference, MD 0.1, 95% CI -0.4 to 0.6, p = 0.70). For people with Parkinson's disease, there was no difference between groups in change in sound pressure levels (monologue) (MD 0.6, 95% CI -1.2 to 2.5, p = 0.49). Four trials investigated interventions for speech sound disorder, voice disorder and post-stroke dysphagia and aphasia; they found no differences between telehealth service delivery and face-to-face delivery.

CONCLUSIONS

Evidence suggests that the telehealth provision of SLP services may be a viable alternative to their provision face-to-face, particularly to people who stutter and people with Parkinson's disease. The key limitation is the small number of randomized controlled trials, as well as evidence on the quality of life, well-being and satisfaction and economic outcomes.

Effectiveness of Voice Therapy in Telepractice with Patients with Hyperfunctional Voice Disorder: A Pilot Study

Background: The need for telepractice and digital treatment has increased due to issues this revision.regarding medical access and the COVID-19 pandemic. However, in many countries, telepractice is rarely performed. The purpose of this pilot study was to describe the detailed process of telepractice in patients with hyperfunctional voice disorder and investigate its effects. Methods: The three subjects who were enrolled in this pilot study had hyperfunctional voice disorders. The evaluation was performed face to face. Auditory perceptual evaluation, acoustic evaluation, aerodynamic evaluation, patient self-evaluation, and interviews were conducted. Treatment was delivered by telepractice using a smartphone application. Results: In quantitative analysis of auditory perceptual evaluation, acoustic evaluation, aerodynamic evaluation, and patient self-evaluation, all subjects showed improved voice after treatment. In-depth analysis of telepractice was performed through the interview. Conclusions: Telepractice was effective in patients with voice disorders, and the patients were satisfied with this approach. In addition to this pilot study, further large-scale studies are required, but telemedicine may improve treatment outcomes and patient satisfaction in cases where medical access is limited or during outbreaks of respiratory infections like COVID-19.

Requirements for the Acceptance of an App for Voice Therapy-A Usability Report Based on the "Oldenburger Logopädie App" (OLA)

OBJECTIVE

The prototype "Oldenburger Logopädie App" (OLA) was designed to support voice therapy for patients with recurrent paresis, such as to accompany homework or as a short-term substitute for regular therapy due to dropouts, such as during the COVID-19 pandemic. The treating speech and language pathologists (SLPs) unlocks videos individually applicable to the respective patients, in which the SLPs instruct the individual exercises. The app can be used without information technology knowledge or detailed instructions.

MATERIALS AND METHODS

The prototype's usability was evaluated through a usability test battery (AttrakDiff questionnaire, System Usability Scale, Visual Aesthetics of Websites Inventory questionnaire) and informal interviews from the perspective of patients and SLPs.

RESULTS

The acceptance, usability, user experience, self-descriptiveness, and user behavior of OLA were consistently given and mostly rated as positive. Both user groups rated OLA as practical and easy to use (eg, System Usability Scale: "practical" (agree: ∅ 49.5%), "cumbersome to use" (total: strongly disagree: ∅ 60.0%). However, the monotonous layout of the app and the instructional and exercise videos should be modified in the next editing step. An overview of relevant criteria for a voice therapy app, regarding design and functions, was derived from the results.

CONCLUSION

This user-oriented feedback on the usability of the voice app provides the proof of concept and the basis for the further development of the Artificial intelligence-based innovative follow-up app LAOLA. In the future, it should be possible to support the treatment of all voice disorders with such an app. For the further development of the voice app, the therapeutic content and the effectiveness of the training should also be investigated.

The Effects of Telerehabilitation in Patients with Voice Disorders: A Systematic Review and Meta-Analysis

OBJECTIVES

To compare the effects of telerehabilitation (TR) and face-to-face rehabilitation (FTF) methods on the outcomes of adults with voice disorders and to analyze the effectiveness of TR.

METHODS

Following Boolean Logic, a search strategy was devised, combining subject terms and keywords based on the interventions and populations outlined in the inclusion criteria. We searched PubMed, Cochrane Library, Embase, Web of Science, Scopus, CNKI, Wanfang, CQVIP databases, and manually screened academic conference papers, journal articles, and gray literature to identify eligible randomized controlled trials (RCTs) on remote voice therapy. Two researchers assessed the risk of bias in the included studies using the risk of bias assessment tool for RCTs outlined in the Cochrane Handbook for Systematic Reviews of Interventions version 5.1.0.

RESULTS

Five trials with a total of 233 patients with voice disorders were included in the study after screening. The results revealed a significant difference in Jitter change values (mean difference [MD]=-0.12, 95%CI [-0.23,-0.01], P = 0.04) between TR and FTF, maximum phonation time (MD=0.76, 95%CI [-0.60,2.13], P = 0.27), Shimmer (MD=-0.04, 95%CI [-0.11,0.03], P = 0.27), voice handicap index (MD=0.87, 95%CI [-1.77,3.50], P = 0.52), and GRBAS(G) (MD=-0.00, 95%CI [-0.01,0.01], P = 0.99) had no significant difference.

CONCLUSION

TR demonstrates comparable efficacy to FTF in voice treatment and is associated with higher levels of patient satisfaction, making it a viable and effective therapeutic modality. However, given the limited sample size analyzed in this study, further validation of this conclusion necessitates additional RCTs with larger sample sizes. Furthermore, researchers should remain cognizant of the constraints associated with TR and consistently refine treatment protocols to enhance the efficacy of voice therapy.

Normative Values of Client-Reported Outcome Measures and Self-Ratings of Six Voice Parameters via the VoiceEvalU8 App

OBJECTIVES

Ecological momentary assessments (EMA) and interventions (EMI) have the potential to assess and offer interventions repeatedly within the client's daily life through mobile app technology. Considering the development of the EMA VoiceEvalU8, the current work provided normative data by comparing traditional (i.e., paper and pencil) and electronic (i.e., VoiceEvalU8 app) administration modalities of client-reported outcome measures and client self-ratings of six voice parameters twice a day in their functional environment.

METHODS

In Experiment 1, 50 vocally healthy cisgender women and men completed the Voice Handicap Index (VHI)-30, VHI-10, and Vocal Fatigue Index (VFI) with paper and pencil and the VoiceEvalU8 app. The order of administration modality and perceptual scales was randomized for each participant. In Experiment 2, 104 vocally healthy cisgender women and men used the VoiceEvalU8 app across five days in the morning before talking all day and in the evening after talking all day to self-rate six voice parameters (i.e., overall quality, roughness, breathiness, strain, pitch, and loudness) on a scale from 0 - 100. Mann Whitney U tests were run for all measures. Means and standard deviations are reported for descriptive analysis and normative values.

RESULTS

In Experiment 1, results showed no significant differences between paper and pencil and VoiceEValU8 app administration for the VHI-30, VHI-10, and VFI for vocally healthy adults. Normative values in the current study were consistent with previous literature for the VHI-10 and VFI factor 1 and 2, but slightly higher for the VHI-30 and slightly lower for the VFI factor 3. In Experiment 2, results demonstrated significant differences for all six voice parameters between the morning and evening log sessions. Normative values demonstrated higher self-ratings in the morning as compared to the evening.

CONCLUSIONS

For vocally healthy adults, completing the VHI-30, VHI-10, and VFI via paper and pencil and the VoiceEvalU8 app yielded the same results. Client self-ratings of six voice parameters on a scale from 0 - 100 twice a day demonstrated that vocally healthy adults perceived voice to be worse in the morning before talking all day as compared to the evening after talking all day. The results from the current work are promising for EMA via the VoiceEvalU8 app and support the need for continued investigations with clients with voice differences, problems, and/or disorders.

Investigation of the effectiveness of articulation therapy through tele-practice on children with cleft palate in Khuzestan Province during COVID-19 pandemic

INTRODUCTION

A cleft palate is a common type of facial malformation. Compensatory articulation errors are one of the important causes of unclear speech in children with cleft palate. Tele-practice (TP) helps to connect therapists and clients for assessment and therapy. Our goal is to investigate the effectiveness of articulation therapy through tele-practice on cleft palate children in Khuzestan Province during the COVID-19 pandemic.

MATERIALS & METHODS

Before starting the treatment, a 20-min speech sample was recorded individually from all the children. Speech intelligibility and the percentage of correct consonants were assessed for each speech sample. The control group received treatment sessions in person at the cleft palate center, and the other group received treatment via tele-practice using the ZOOM platform. Treatment sessions were provided in the form of 45-60-min group sessions, twice a week, for 5 weeks (10 sessions in total). After 10 treatment sessions, the speech sample was recorded again. The level of parental satisfaction was measured using a Likert 5-level survey.

RESULTS

The mean score of intelligibility of the two groups decreased (-1.4400 and 0.7200). The two groups' mean percentage of correct consonants increased. (26.09 and 17.90). In both groups, the mean score of parents' satisfaction with the treatment was high (3.44 and 3.84). The mean of difference before and after the speech intelligibility and the percentage of correct consonants variables in both groups was statistically significant (P = 0.001 and P = 0.002, respectively). In both groups, the satisfaction variable was not associated with a statistically significant difference (P = 0.067).

CONCLUSION

The effectiveness of in-person therapy over a certain period of time is higher than tele-practice. Nevertheless, the results demonstrated an increase in the intelligibility of speech and the percentage of correct consonants in both groups, thus proving the effectiveness of articulation therapy in correcting compensatory articulation errors in children with cleft palate through in-person and tele-practice.

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

PURPOSE

Rehabilitation intervention descriptions often do not explicitly identify active ingredients or how those ingredients lead to changes in patient functioning. The Rehabilitation Treatment Specification System (RTSS) provides guidance to identify the critical aspects of any rehabilitation therapy and supported the development of standardly named ingredients and targets in voice therapy (Rehabilitation Treatment Specification System for Voice Therapy [RTSS-Voice]). This study sought to test the content validity of the RTSS-Voice and determine if the RTSS-Voice can be used to identify commonalities and differences in treatment (criterion validity) across clinicians in everyday clinical practice.

METHOD

Five speech-language pathologists from different institutions videotaped one therapy session for 59 patients diagnosed with a voice or upper airway disorder. Specifications were created for each video, and iterative rounds of revisions were completed with the treating clinician and two RTSS experts until consensus was reached on each specification.

RESULTS

All 59 sessions were specified without the addition of any targets or ingredients. There were two frequent targets: (a) increased volition and (b) decreased strained voice quality. There were three frequent ingredients: (a) information regarding the patient's capability and motivation to perform a therapeutic behavior, (b) knowledge of results feedback, and (c) opportunities to practice voicing with improved resonance and mean airflow. Across sessions treating vocal hyperfunction, there was large variability across clinicians regarding the types and number of treatment components introduced, types of feedback provided, and vocal practice within spontaneous speech and negative practice.

CONCLUSIONS

The RTSS and the RTSS-Voice demonstrated strong content validity, as they comprehensively characterized 59 therapy sessions. They also demonstrated strong criterion validity, as commonalities and differences were identified in everyday voice therapy for vocal hyperfunction across multiple clinicians. Future work to translate RTSS principles and RTSS-Voice terms into clinical documentation can help to understand how clinician and patient variability impacts outcomes and bridge the research-practice gap.

A Systematic Review of Speech-Language Pathology Interventions for Presbyphonia Using the Rehabilitation Treatment Specification System

BACKGROUND

The prevalence of voice disorders for people aged >65 years is four times higher than for the population at large. The most common cause of dysphonia in this group is presbyphonia, the preferred first-line treatment for which is voice therapy with a speech-language pathologist. This systematic review seeks to identify how voice therapy affects multidimensional voice outcomes in people with presbyphonia.

METHODS

A systematic search of CINAHL, Embase, Emcare, MEDLINE, and Google Scholar was conducted in March 2023. Comparative and noncomparative studies of voice therapy in participants aged >50 years with presbyphonia were considered for inclusion. No limitations were placed on date or language of publication. Study quality and risk of bias were assessed with the Cochrane Risk of Bias 2 tool and the Methodological Index for Non-Randomized Studies. Subgroup analysis was used to compare studies based on participant sex, intervention duration, study design, and intervention content. Interventions were specified using the Rehabilitation Treatment Specification System (RTSS) employing a consensus methodology among reviewers. The results were synthesized utilizing meta-analysis when outcomes were adequately specified and narrative analysis when they were not.

RESULTS

Twenty-three studies were included with 1050 subjects (mean age: 72.5 ± 8.6 years; 51% female). The most reported intervention was vocal function exercises. Per the RTSS, 14 interventions employed a predominantly Organ Functions approach, and the 14 remaining interventions employed a Skills & Habits approach. Meta-analysis confirmed posttherapy improvement in patient-related outcome measures of 0.93 standard mean difference (P < 0.00001, 95% confidence interval [CI]: 0.70-1.17); studies with predominantly males and with longer treatment periods were associated with larger improvements, while randomized controlled trials reported more modest improvements. Meta-analysis also identified a mean posttherapy increase in maximum phonation time (MPT) of 5.37 seconds (P < 0.00001, 95% CI: 3.52-7.22). Treatments with an Organ Functions focus resulted in greater gains in MPT than those with a Skills & Habits focus (7.52 seconds versus 2.90 seconds). Finally, meta-analysis identified reductions in acoustic perturbation measures (jitter: 0.62%, P < 0.001, 95% CI: 0.26%-0.97%; shimmer 1.05%, P < 0.00001, 95% CI: 0.67%-1.44%). Narrative synthesis further identified improvement in auditory-perceptual voice quality in all active treatment groups as well as improved glottal function in most studies that reported this.

CONCLUSIONS

Despite the uncertainty around internal validity introduced by the inclusion of a wide range of study designs, there is convincing evidence that voice therapy for presbyphonia results in significant improvement in patient-reported, aerodynamic, acoustic, and expert-rated voice outcomes. Treatments with an Organ Functions focus may better address the underlying physiological deficits of presbyphonia, although future comparative studies with multidimensional voice assessment are warranted.

Observations and Considerations for Implementing Remote Acoustic Voice Recording and Analysis in Clinical Practice

OBJECTIVES/HYPOTHESIS

Remote voice recording and acoustic analysis allow for comprehensive voice assessment and outcome tracking without the requirements of travel to the clinic, in-person visit, or expensive equipment. This paper delineates the process and considerations for implementing remote voice recording and acoustic analysis in a high-volume university voice clinic.

STUDY DESIGN

Clinical Focus.

METHODS

Acoustic voice recordings were attempted on 108 unique patients over a 6-month period using a remote voice recording phone application. Development of the clinical process including determining normative data in which to compare acoustic results, clinician training, and clinical application is described. The treating Speech Language Pathologists (SLPs) were surveyed 2 months after implementation to assess ease of application, identify challenges and assess implementation of potential solutions.

RESULTS

Of 108 unique patients, 83 patients were successful in completing the process of synchronous remote acoustic voice recording in conjunction with their SLP clinician. The process of downloading the application, setting up, and obtaining voice recordings was most commonly 10-20 minutes according to the 8 SLPs surveyed. Challenges and helpful techniques were identified.

CONCLUSIONS

Remote acoustic voice recordings have allowed SLPs to continue to complete a comprehensive voice evaluation in a telepractice model. Given emerging knowledge about the viability of remote voice recordings, the success in obtaining acoustic data remotely, and the accessibility of a low-cost app for SLPs makes remote voice recordings a viable option to facilitate remote clinical care and research investigation.

Effectiveness and Feasibility of Telepractice on Voice Therapy for Female Teachers in Elementary Schools with Self-Reported Voice Disorders

PURPOSE

The purpose of this study is to explore the effectiveness of telepractice in voice intervention for female teachers in elementary schools with self-reported voice disorders.

METHODS

Thirty-five female elementary school teachers with self-reported voice disorders volunteered to participate in the study. They were divided into a telepractice voice intervention group (experimental group N=18) and a face-to-face voice intervention group (control group N=17) based on their employment setting. The exact same treatment protocol was applied to both groups of subjects, except that the intervention group was seen through telepractice, and the control group was seen face-to-face. The treatment protocol includes vocal hygiene education and resonant voice therapy twice a week for a total of eight sessions. Auditory perceptual analysis, acoustic assessment, aerodynamic assessment and self-assessment protocol were conducted before the intervention and one week after the last intervention, and the differences before and after interventions within each group and between groups were compared.

RESULTS

There was no significant difference in baseline data including age, working years, and voice symptoms between the two groups. Both groups showed significant improvement (P<0.05) in all voice assessment before and after the treatment sessions, except for the Voice Handicap Index-10 (VHI-10) assessment. No statistical difference was found in other pre- and post-intervention voice assessment changes between the two study groups. The control group presented higher improvement in the total score, and the two subdomain assessments of physiology and emotion.

CONCLUSIONS

Telepractice voice intervention can effectively improve the voice quality of female teachers in elementary schools, and telepractice therapy can be an effective alternative to face-to-face voice intervention.

Remote Voice Therapy With an Oscillatory Positive Expiratory Pressure Device in Subjects With Vocal Fatigue: A Randomized Controlled Trial

PURPOSE

The present study aimed at assessing the efficacy of remote voice therapy (telepractice) implemented with Shaker Medic Plus device in subjects with vocal fatigue.

METHOD

Thirty-six participants were initially enrolled in this study. Twenty-four participants with vocal fatigue were finally randomly assigned to one of two treatment groups: (a) voice treatment with Shaker Medic Plus device plus vocal hygiene program (n = 12) and (b) voice treatment with water resistance therapy (WRT) plus vocal hygiene program (n = 12). Laryngoscopic assessment was conducted on all subjects. Before and after voice therapy, participants underwent (a) self-assessment of voice: Vocal Fatigue Index and Vocal Tract Discomfort Scale and (b) instrumental assessment with aerodynamic, acoustic, and electroglottographic measures. The treatment period included six voice therapy sessions within 6 weeks. Each session lasted 30 min. For both groups, exercises consisted of a sequence of nine phonatory tasks performed with Shaker Medic Plus (experimental group) and WRT (control group). Comparisons for all variables were performed between the experimental group and control group.

RESULTS

Significant improvements were found for self-reported variables when comparing pre- and postmeasures for both groups. No significant differences were found when comparing groups. No significant main effects or interactions were observed for any of the observed instrumental variables.

CONCLUSIONS

Remote physiologic voice therapy with Shaker Medic Plus device and water resistance therapy seem to be both effective to improve voice in subjects diagnosed with vocal fatigue. No differences should be expected between these therapeutic protocols when treating patients with vocal fatigue. Moreover, both are effective at reducing tiredness of voice, voice avoidance, physical discomfort associated with voicing, subjective perception of sensory discomfort in throat, and reduction of physical, emotional, and functional impact of voice problems.

Are smartphones and low-cost external microphones comparable for measuring time-domain acoustic parameters?

PURPOSE

This study examined and compared the diagnostic accuracy and correlation levels of the acoustic parameters of the audio recordings obtained from smartphones on two operating systems and from dynamic and condenser types of external microphones.

METHOD

The study included 87 adults: 57 with voice disorder and 30 with a healthy voice. Each participant was asked to perform a sustained vowel phonation (/a/). The recordings were taken simultaneously using five microphones AKG-P220, Shure-SM58, Samson Go Mic, Apple iPhone 6, and Samsung Galaxy J7 Pro microphones in an acoustically insulated cabinet. Acoustic examinations were performed using Praat version 6.2.09. The data were examined using Pearson correlation and receiver-operating characteristic (ROC) analyses.

RESULTS

The parameters with the highest area under curve (AUC) values among all microphone recordings in the time-domain analyses were the frequency perturbation parameters. Additionally, considering the correlation coefficients obtained by synchronizing the microphones with each other and the AUC values together, the parameter with the highest correlation coefficient and diagnostic accuracy values was the jitter-local parameter.

CONCLUSION

Period-to-period perturbation parameters obtained from audio recordings made with smartphones show similar levels of diagnostic accuracy to external microphones used in clinical conditions.

Addressing disparities in speech-language pathology and laryngology services with telehealth

The COVID-19 pandemic disproportionately affected the health and well-being of marginalized communities, and it brought greater awareness to disparities in health care access and utilization. Addressing these disparities is difficult because of their multidimensional nature. Predisposing factors (demographic information, social structure, and beliefs), enabling factors (family and community) and illness levels (perceived and evaluated illness) are thought to jointly contribute to such disparities. Research has demonstrated that disparities in access and utilization of speech-language pathology and laryngology services are the result of racial and ethnic differences, geographic factors, sex, gender, educational background, income level and insurance status. For example, persons from diverse racial and ethnic backgrounds have been found to be less likely to attend or adhere to voice rehabilitation, and they are more likely to delay health care due to language barriers, longer wait times, a lack of transportation and difficulties contacting their physician. The purpose of this paper is to summarize existing research on telehealth, discuss how telehealth offers the potential to eliminate some disparities in the access and utilization of voice care, review its limitations, and encourage continued research in this area. A clinical perspective from a large volume laryngology clinic in a major city in northeastern United States highlights the use of telehealth in the provision of voice care by a laryngologist and speech-language pathologist during and after the COVID19 pandemic.

Reducing Vocal Fatigue While Preserving Realism During Video Game Voice-Overs Using the Vocal Combat Technique: A Randomized Controlled Trial

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.

Introduction of Voice Type Component (VTC) as an Effective Acoustic Voice Analysis Method in Tele-evaluation

OBJECTIVE

Telepractice in voice health care and evaluation services has attracted much attention in recent years. Multiple studies have proven the effectiveness of voice therapy with telepractice. However, voice evaluations are still mostly conducted in person due to the lack of sensitive acoustic analysis methods.

METHODS

This study examined various acoustic analysis methods for voice evaluation in telepractice. Eighteen female elementary school teachers with self-reported voice disorders volunteered to participate in the study. Speech samples were collected before and after the interventions using two voice sampling methods concurrently. One set of data was collected using the traditional voice sample collection method by the therapist in person. The second set of data was collected on the same speech samples using the clients' own smartphones, and the collected voice samples were later sent to the researcher for further acoustic analysis. The voice type component (VTC) measurement represented the proportion of different VTCs in a voice by measuring the chaos and intrinsic dimension.

RESULTS

Voice analyses were conducted on both sets of data, and the correlation between the two sampling procedures was analyzed. It appears that the VTC could be a more reliable method for producing acoustic analysis results with voice samples collected from smartphones compared to other objective voice assessment procedures. This reliability has been demonstrated via statistical analysis, including correlation coefficient, pairwise t test, d-prime, and area under the curve. The results of this study highlighted the VTC as an effective and accurate acoustic analysis method in tele-evaluation.

CONCLUSIONS

This feasible voice sampling method, which utilizes participants' own smartphones, will reduce barriers to accessing limited voice specialists due to distance and will decrease the cost of care by minimizing expenses associated with travel and additional equipment for voice sampling. Ultimately, this approach will enhance the effectiveness of voice care delivered through telepractice to patients in remote and underserved areas.

Rapid Implementation of Teletherapy for Voice Disorders: Challenges and Opportunities for Speech-Language Pathologists

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.

A Comparison of Voice Therapy Attendance Rates Between In-Person and Telepractice

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.

Effect of Behavioral Cough Suppression Therapy Delivered via Telehealth

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.

Framing Disparities in Access to Medical Speech-Language Pathology Care in Rural Alabama

PURPOSE

Rural-living residents of Alabama depend on rural hospitals and clinics staffed with physicians and allied health professionals including speech-language pathologists (SLPs). The purpose of the exploratory study was to examine the speech-language pathology workforce in health care facilities in nonmetropolitan Alabama counties to determine potential disparities in access and identify medical SLP deserts for rural Alabamians.

METHOD

The hospitals, rural health clinics, nursing homes, and rehabilitation centers for each of the 37 nonmetropolitan counties were identified through the 2020 Alabama Department of Public Health directories, and phone surveys were completed to determine medical SLP staffing at each facility. Descriptive statistics and regression analysis were conducted.

RESULTS

The initial review yielded 229 rural health care facilities with 223 ultimately included in the analysis and 176 facilities completing a phone inquiry (76.68%). Sixty-one (35.88%) reported employing at least one SLP and no facility stated staffing SLP assistants. Linear regression indicated a positive, yet moderate effect size between the reported number of SLPs staffed within each county and specific population of the county (r ² = .519). Anecdotally, facilities reported difficulty in hiring and retaining SLPs due to rural geographical location.

CONCLUSIONS

The exploratory findings suggest disparities in access to behavioral communication and swallowing care for rural residents in the state. The methodology employed for data collection and analysis may be applied to other states and U.S. territories, in an effort to frame the issue nationally and support rural health care policy across the United States. Further investigation regarding the cost effectiveness of telepractice, the availability of broadband Internet access, the efficacy of community-based service delivery, and the effectiveness of incentivized rural SLP graduate programs is warranted to mitigate the disparities in access.

Multi-dimensional investigation of the clinical effectiveness and prognostic factors of voice therapy for benign voice disorders

BACKGROUND/PURPOSE

Voice therapy is frequently recommended as the first-line treatment for benign voice disorders. This study investigated the clinical effectiveness of voice therapy and the prognostic factors of treatment outcomes.

METHODS

We recruited 103 consecutive patients with voice disorders, namely vocal nodules, polyps, and muscle tension dysphonia (MTD), from September 2014 to July 2016. All the patients received voice therapy as the primary treatment. Treatment outcomes were evaluated using auditory perceptual evaluation, acoustic analysis, maximum phonation time, and 10-item voice handicap index (VHI-10). Clinical effectiveness of voice therapy was defined by either 1) a posttreatment VHI-10 score ≤ 10 points or 2) decline of VHI-10 ≥ 4 points.

RESULTS

After voice therapy, VHI-10 and perceptual rating of voice quality improved significantly (p < 0.05) in the three disease categories. In patients with nodules, all the outcome parameters improved significantly (p < 0.05). Patients with good adherence to voice therapy (attending more than four sessions) had a significantly higher effectiveness than those with poor adherence (87% vs. 64%, p < 0.05). Patients with high occupational vocal demand also demonstrated a better effectiveness than those with routine vocal demand (90% vs. 70%, p < 0.05). Subsequent multivariate analyses revealed that adherence and vocal demand were independently and significantly correlated with clinical effectiveness (p = 0.03).

CONCLUSION

Voice therapy is effective for patients with vocal nodules, polyps, and MTD. Adherence to voice therapy and occupational vocal demand are significant prognostic factors for treatment outcomes.

A Nonrandomized Trial for Student Teachers of an In-Person and Telepractice Global Voice Prevention and Therapy Model With Estill Voice Training Assessed by the VoiceEvalU8 App

Purpose This study investigated the effects of the in-person and telepractice Global Voice Prevention and Therapy Model (GVPTM) treatment conditions and a control condition with vocally healthy student teachers. Method In this single-blinded, nonrandomized trial, 82 participants completed all aspects of the study. Estill Voice Training was used as the stimulability component of the GVPTM to train multiple new voices meeting all the vocal needs of the student teachers. Outcomes were assessed using acoustic, perceptual, and aerodynamic measures captured by the VoiceEvalU8 app at pre and post in fall and during student teaching in spring. Results Significant improvements were achieved for several acoustic and perceptual measures in the treatment conditions, but not in the control condition. The in-person and telepractice conditions produced similar results. The all-voiced phrase and connected speech were more successful in demonstrating voice change for some of the perturbation measures as compared to sustained /a/. Conclusions The treatment conditions were successful in improving the participants' voices for fundamental frequency and some acoustic perturbation measures while maintaining the improvements during student teaching. In addition, the treatment conditions were successful in decreasing the negative impact of voice-related quality of life and vocal fatigue during student teaching. Future research should address the effectiveness of the various components of the GVPTM, the application of the GVPTM with patients with voice disorders, the relevance of defining auditory-perceptual terms by the anatomy and physiology of the voice production system (i.e., Estill Voice Training), and the continued use of the VoiceEvalU8 app for clinical voice investigations.
