Effect of an iOS App on Voice Therapy Adherence and Motivation

Patient Motivation for Voice Therapy Increases After Stimulability Testing: Validation of a Voice Therapy Motivation and Voice Perception Inventory

OBJECTIVE

Measuring patient motivation for voice therapy is an important component of determining prognosis and estimating compliance. Voice stimulability testing is assumed to influence the patient's motivation by improving their perception of the sound and/or feel of the voice. The purpose of this study was to validate a Voice Therapy Motivation and Voice Perception Inventory and to determine whether stimulability testing elicits improvements in motivation and patient-perceived voice status.

METHOD

Seventy-five patients who underwent initial voice therapy evaluation completed a four-item inventory that queried their commitment to voice therapy, confidence that they could change their voice through voice therapy, perception of their voice severity, and ratings of their vocal effort. Inventories were completed shortly before and after stimulability testing. A psychometric analysis of the survey was conducted, including the internal consistency of each construct of the inventory along with content, predictive, and concurrent validity. Paired-samples statistical analyses were conducted to determine differences before and after stimulability testing, and Spearman correlations between voice and motivation ratings were conducted to determine relationships between the patient's perception of their voice and their motivation for voice therapy.

RESULTS

Internal consistency reliability was acceptable to good for each construct, particularly after stimulability testing. Motivation scales were predictive of returning for voice therapy sessions, subjective improvement of voice by the first therapy session, and likelihood of the patient practicing the home practice program. Patient ratings of voice severity and effort were positively correlated with clinician ratings of overall severity. Motivation and voice impairment perception improved following stimulability testing. Reduction in vocal effort was related to improved motivation, but change in voice severity was not.

CONCLUSIONS

Voice stimulability testing can influence patient motivation for voice therapy and patient-perceived voice improvements. It should be considered a critical part of the voice evaluation.

Clinical Effects of Voice Therapy on Vocal Outcomes in Unilateral Vocal Fold Paralysis: Proof-of-Concept Study for Two SOVT-Based Treatment Protocols

BACKGROUND

Studies on treatment efficacy in unilateral vocal fold paralysis (UVFP) often lack a predetermined treatment protocol, and little is known about the effects of specific vocal techniques on vocal outcomes and quality of life in UVFP patients. The purpose of this preliminary proof-of-concept study is to investigate the effects and feasibility of two intensive treatment protocols based on water-resistance therapy (WRT) and vocal function exercises (VFE).

METHODS

Ten participants with acute or chronic UVFP/paresis were recruited in the study and randomly assigned to the WRT or VFE group. Three of these participants presented with aphonia and could not complete the program as prescribed. The remaining participants completed an intensive therapy program with the assigned vocal technique. Before, during, and after the program, a multidimensional voice assessment was performed. Maximum phonation time, acoustic, perceptual, and patient-reported outcome measures (PROMs) were obtained.

RESULTS

WRT and VFE had positive clinical effects on instrumental and auditory-perceptual voice quality, glottal closure, and PROMs, but interindividual variability was high. Studies with larger sample sizes are necessary to confirm or refute these findings.

CONCLUSION

The WRT- and VFE-based therapy programs are both feasible and seem to elicit positive clinical changes in UVFP patients. Suggestions on how to improve the programs are provided, as well as considerations for implementation in clinical practice. Follow-up research is needed to examine the efficacy of both programs on group level.

The Relationship Between Speech-Language Pathologists' Perceptions of Clinical Terminology and Its Use in Voice Therapy with Adults

OBJECTIVES

The terminology used by speech-language pathologists (SLPs) during voice therapy is important for treatment outcomes because it can impact both patient self-efficacy and adherence. However, little is known about what factors influence the terminology that SLPs choose to use. Understanding this gap is important to ultimately optimize voice therapy outcomes. Therefore, the primary aims of this study were to (1) assess the relationship between reported clinician-perceived positivity and (2) assess the relationship between clinician-perceived positivity and clinical endorsement for use. We hypothesized that clinician-perceived positivity would be one important factor driving how frequently clinicians use or avoid specific terms, and if they think the term should be used by other SLPs in clinical practice.

DESIGN/METHODS

This prospective study was conducted as an online survey of SLPs and SLP clinical fellows who evaluate and treat adult voice patients. The survey presented respondents with a total of 46 voice-related terms and prompted respondents to rate: (1) how frequently they use a specific voice-related term ("frequency of use"); (2) how positive or negative they perceive a specific voice-related term to be ("perceived positivity"); and (3) if they feel a specific voice-related term should versus should not be used in clinical practice ("clinical endorsement"). Inferential statistics were used to examine the relationship between perceived positivity and frequency of use, and perceived positivity and clinical endorsement. Summary statistics were used to describe frequency of use across all terms.

RESULTS

One hundred twelve respondents completed the survey. Clinician-perceived positivity of voice-related terminology was significantly related to its reported self-reported frequency of use (β = 1.946; 95% CI: 1.701-2.191; P < 0.0005) and clinical endorsement of use by others (β = 4.103; 95% CI: 3.750-4.456; P < 0.0005). Both of these relationships exhibited relatively large effect sizes.

CONCLUSIONS

This study was an important first step at identifying factors that influence SLP's use of specific terminology in voice therapy. Specifically, an SLP's perceived positivity of clinical terminology strongly influenced the frequency with which they reported using that term in voice therapy and whether or not they thought that term should be used with patients by other SLPs in voice therapy. Future work should investigate clinician characteristics that might affect terminology use, include more diverse sampling, utilize self-selected terminology or audio recordings of therapy interactions, and assess direct effects of terminology use on patient outcomes.

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.

Design and usability evaluation of a web-based pitch control training app for transgender women

Transgender people often experience dysphoria because the way their voice is perceived does not match their gender identity. Such dysphoria negatively affects mental health and quality of life, and is particularly an issue in trans women. Dysphoria can be reduced via gender-affirming voice and communication training provided by human experts, but the accessibility of such training is often limited. As a supplement or alternative to human-guided training, our team has thus developed an early prototype of voice training software for transfeminine users (i.e., trans women and nonbinary users who were assigned male at birth). The software is accessible via a web browser and provides three vocal pitch exercises together with real-time feedback about the user's pitch relative to a desired target pitch curve. This paper presents the main technical features and results of a single-session usability evaluation with 5 transfeminine participants. We further present future plans for expansion to other exercises and voice aspects (particularly resonance) as well as plans for clinical trials.

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.

Scoping Review of Voice Therapy Adherence

OBJECTIVES

The purpose of this scoping review was to summarize key findings in the voice therapy adherence literature for individuals with phonotraumatic lesions. The particular focus was to identify how adherence has been defined and measured (operationalization and criteria for successful adherence) and to describe variables which were found to have a positive, neutral, or negative relationship with adherence to voice therapy.

METHODS

Data were identified and charted using the PRISMA-ScR protocol via searches of CINAHL, PsycINFO, Pubmed, SCOPUS, and Web of Science.

RESULTS

Literature mining revealed that adherence is rarely defined but is usually operationalized. "Successful completion of therapy" was the most common operationalization. Most variables studied in this field have been found to have no relationship with adherence. An incidental finding was that, most frequently, researchers have repeatedly studied variables which have already been documented to have no relationship with adherence.

CONCLUSION

Research into voice therapy adherence is still emerging, and few if any variables have been identified which are strongly associated with adherence to voice therapy for people with phonotraumatic lesions. Inspiration for future research may be drawn from other disciplines, which point to relationship variables as central to the adherence process. Examination of such variables is currently underrepresented in the voice therapy literature; we suggest this and other gaps for pursuit in future research.

Parents' Perceptions of and Attitudes Toward Voice Therapy

PURPOSE

This study aimed to investigate Chinese parents' perceptions of pediatric voice disorders to determine their level of health literacy and knowledge gaps to understand the determinants of initiating voice therapy for children with dysphonia.

METHOD

A cross-sectional survey was conducted in three voice clinics in Chengdu, China, from October 1, 2021, to October 1, 2022. Impairment of children's quality of life as perceived by parents was assessed using the pediatric Voice-Related Quality-of-Life (pVRQOL) scale.

RESULTS

Overall, 206 parents whose children were recommended voice therapy were recruited (Mean ± SD age, 35.0 ± 4.62 years; male/female = 1:3). When otolaryngologists recommended that their children with dysphonia initiate voice therapy, most participants had positive responses (n = 176, 85.4%). The mean pVRQOL score was 40.8 in the accept group and 37.6 in the reject group (difference, 1.7; 95% CI, -4.98 1.69). Participants who had a more influential work status, had an only-child, had children with shorter-term voice symptoms, and visited specialized hospitals were more likely to have negative practices related to children's voice therapy (P < 0.05).

CONCLUSIONS

This study represents an important first step in understanding Chinese parents' perceptions of and motivations for initiating voice therapy for their children with dysphonia. Initiation of treatment as recommended in pediatric populations depends on multiple factors, such as the duration of voice symptoms, family structure, and hospital type. It is imperative to promote public health care education on voice therapy among parents, as health care literacy is the primary driving factors in decision-making.

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.

Update on the pediatric adverse vocal behavior voice disorders: a clinical practice review

The main causes of voice disorders in children with adverse vocal behavior include benign lesions of the vocal folds caused by voice abuse or misuses, such as vocal fold nodules, vocal fold polyps, and laryngitis. Long-term voice disorders can affect the physical and mental health of children. Reviewing the literature of the last two decades on "Vocal Fold Nodules," "Vocal Fold Polyp," "Voice disorder," "Voice Abuse," "Voice Misuse," "Pediatrics," and "Children" with the appropriate Boolean operators.  Conclusion: A total of 315 results were returned on an initial PubMed search. All articles from 2000 to 2022 written in English or Chinese were screened. Duplicate articles, those relating to adults only or concerned with the malignant lesion of the vocal cord, were excluded, resulting in 196 articles of interest. Relevant references and books have also been consulted, and we provide a review of the pathogenesis, diagnosis, and treatment of these maladaptive vocal behavioral voice disorders. What is Known: • Hoarseness is the most common voice symptom in children, and there are various causes of hoarseness in children. However, there is a lack of reviews on voice disorders caused by adverse vocal habits in children. • Voice training is a conservative treatment method for children with voice disorders , and it is important to clarify the factors that influence the effectiveness of voice training for children. What is New: • This review of the personality and family characteristics of children with adverse vocal behavioural voice disorders provides a valuable guide to the clinical planning of subsequent treatment. • This article discusses and summarises some of the factors that may influence the effectiveness of voice training in children and collates some of the scales and questionnaires currently used in children that are important in predicting the effectiveness of voice training.

Developing and Testing a Smartphone Application to Enhance Adherence to Voice Therapy: A Pilot Study

The present study aimed to develop a smartphone application (app) that addressed identified barriers to success in voice therapy; accessibility, and poor adherence to home practice. The study objectives were (1) to investigate if app use enhanced adherence to the home practice of voice therapy and (2) to test app usability. Maximizing the effectiveness of voice therapy is vital as voice disorders are detrimental to personal and professional quality of life. A single-blinded randomized clinical trial was completed for the first objective. Participants included normophonic individuals randomly assigned to the app group or the traditional group. The primary outcome measure was adherence measured as the number of missed home practice tasks. The second objective was completed through usability testing and a focus group discussion. The app group (n = 12) missed approximately 50% less home practice tasks as compared to the traditional group (n = 13) and these results were statistically significant (p = 0.04). Dropout rates were comparable between the two groups. Usability results were positive for good usability with high perceived usefulness and perceived ease of use. App use resulted in improved adherence to home practice tasks. App usability results were positive, and participants provided specific areas of improvement which are achievable. Areas for improvement include app engagement and willingness to pay.

Feasibility and Preliminary Efficacy of Two Technology-assisted Vocal Interventions for Older Adults Living in a Residential Facility

OBJECTIVES/HYPOTHESIS

An increasing number of older adults are seeking behavioral voice therapy to manage their voice problems. Poor adherence to voice therapy is a known problem across all treatment-seeking populations. Given age-related physical and cognitive impairments and multiple chronic conditions, older adults are more susceptible to low adherence to behavioral therapies. The purpose of this study was to test the feasibility of an at-home, vocal training intervention for older adults without a known voice disorder living in a senior living community, as well as compare the effects of two modes of mobile health (mHealth) technology-assisted vocal training targeting vocal function and adherence in older adults.

STUDY DESIGN

Cohort Study (Prospective Observational Study).

METHODS

Twenty-three individuals were recruited from a single residential retirement community and randomly allocated into two experimental groups. Both groups were asked to practice the Vocal Function Exercises with increasing frequency over an 8-week period. Tablets with instructions for performing the exercises were provided to all participants. The feedback group's tablets also contained an application providing real-time feedback on pitch, loudness, and duration. Acoustic and aerodynamic measures of vocal function and cognitive measures were obtained before and after the intervention. Self-reported measures of practice frequency, perceived vocal progress and changes, and motivation were obtained weekly.

RESULTS

The feedback control group adhered to the requested practice sessions more in the latter half of the intervention (weeks 5 and 8). Vocal function measures remained stable. Overall, a pattern reflecting self-reported vocal progress and a general improvement in working memory and global cognitive functioning was observed in the feedback group.

CONCLUSIONS

This study demonstrated that an 8-week mHealth intervention is viable to facilitate vocal practice in older adults. Although vocal ability did not improve with training, results indicated that vocal performance remained stable and age-related vocal changes did not progress. Future research on implementation of mHealth applications in conjunction with behavioral voice therapy is warranted to assess adherence and improvements in vocal function in individuals with age-related voice problems.

A Systematic Review of Adherence Strategies for Adult Populations in Speech-Language Pathology Treatment

PURPOSE

Speech-language pathologists (SLPs) often advise adult patients to complete at-home programs in order to improve outcomes. Despite this widespread practice, relatively little is known about treatment adherence. The purposes of this systematic review were to identify adherence strategies and adherence tracking methods used by adult populations that are commonly treated by SLPs (i.e., dysphagia, aphasia, traumatic brain injury, dysphonia, dysarthria), and to identify the efficacy of these strategies.

METHOD

The systematic review was conducted in accordance with A Measurement Tool to Assess Systematic Reviews guidelines. A comprehensive literature search was performed in three databases (CINAHL, PubMed, and Web of Science).

RESULTS

Of the 679 articles found, 18 were selected for analysis. Two thirds of the included articles received the second highest rating on the 5-point JAMA Quality Rating Scheme. Interventions designed to alter treatment adherence included (most to least frequent) computer programs, portable devices/phone apps, alarm reminders, instructional DVDs, check-ins from a clinician/volunteer, and wearable device. Adherence reporting methods included (most to least frequent) self-report diaries, computer program/app-aided collection, wearable device, and clinician/volunteer observation. Of the articles that reported practice frequency, 58% found that adherence strategies improved practice frequency as compared to control. Of the articles that reported treatment outcomes, 66% found that adherence strategies were associated with improved treatment outcomes as compared to control.

CONCLUSIONS

The paucity of publications reviewed suggests that treatment adherence is considerably understudied in speech-language pathology. A clearer understanding of how to improve the design of adherence strategies could yield highly valuable clinical outcomes.
