Relationship Between Adherence to Speech Therapy in Patients With Dysphonia and Quality of Life

Volitional and Non-volitional Devices Used in Voice Therapy and Training: A Scoping Review-Part A

OBJECTIVE

To map the volitional and non-volitional devices used by speech and language pathologists (SLPs) in voice training and therapy and characterize their use in research on voice interventions.

METHODS

This scoping review is the first part of a larger study. The electronic search was carried out by mapping the references in PubMed/Medline, LILACS/BVS, Scopus, Web of Science, EMBASE, and the Cochrane Library, and the manual search was carried out in the grey literature. Two blind independent reviewers selected and extracted data; divergences were solved by consensus. The data extracted in this part of the study were the authorship and year of publication, country, study design, sample characteristics, intervention modality, ingredient, target, mechanism of action, dosage, and outcome measures. They were addressed with descriptive analysis.

RESULTS

Publications that use devices as ingredients are mostly from the last two decades, mainly carried out in the United States of America and Brazil, in adults of both sexes with behavioral dysphonia. Forty-two types of devices were used, many of them with similar approaches but different nomenclatures. Most devices were used voluntarily, focusing on vocal function, and aiming to increase source and filter interaction. Most studies used silicone tubes. The most reported technical specification to apply the ingredient was surface electrodes on the neck. Device dosage was time-controlled, and the most used outcomes were self-assessment and acoustic analysis.

CONCLUSION

Devices are currently used as ingredients in vocal interventions, with a greater focus on increasing the source and filter interaction, associated with silicone tubes (the most used devices in these studies), which have been dosed with performance time. Outcomes were measured with self-assessment instruments.

Initial Theoretical Discussion of Identity as Barrier and Facilitator in Voice Habilitation and Rehabilitation

OBJECTIVES

The purpose of this paper is to review seminal identity theories grounded in social psychology and one concept from voice science and explain how this group may point to identity factors facilitating or impeding voice habilitation and rehabilitation.

METHODS

Identity theories from the social psychology literature (Dramaturgical Theory, Self-Categorization Theory, Self-Determination Theory, Identity Negotiation Theory) and vocal congruence are described. Concepts are synthesized with voice science research to explore potential identity-behavior relations at play in voice habilitation and rehabilitation.

RESULTS

Applicable concepts from social psychology and voice science suggest identity-related processes by which a client may or may not develop a voice difference/disorder, seek intervention, and achieve goals in intervention. A bidirectional relationship between identity and behavior has been well-established in the social psychology literature. However, the relevance of vocal behavior has yet to be formally examined within this literature. Importantly, although connections between behavioral tendencies and voice disorders as well as the contribution of identity to gender-affirming voice treatment have been established in the voice science literature, the consideration of identity's possible role in voice habilitation and rehabilitation in cis gender individuals has thus far been scant.

CONCLUSIONS

Research into identity and voice habilitation and rehabilitation may help to improve voice intervention outcomes. A possible adjunct to human studies is agent-based modeling or other computational approaches to assess the myriad factors that may be relevant within this line of inquiry.

The role of patient perceptions and hyperfunctional voice disorders in predicting voice therapy attendance

OBJECTIVES/HYPOTHESIS

Attendance is essential to voice therapy's effectiveness in the treatment of voice and laryngeal disorders. With such high rates of drop-out and non-attendance, it is important to understand the factors that influence this behavior. This study sought to identify potential predictors of attendance to voice therapy at an interdisciplinary voice clinic.

STUDY DESIGN

Single-institution retrospective cohort study.

METHODS

In this retrospective cohort study, patients evaluated at an interdisciplinary voice clinic who received a referral for voice therapy were identified. Age, gender, voice-related diagnoses, Voice Handicap Index-10 scores, Reflux Symptom Index scores, and measures of patient perceptions (self-rated severity, importance of voice in one's life, and "feelings about voice therapy") were recorded to evaluate associations with attendance to at least one therapy session. Standard statistical analysis and logistic regressions were performed.

RESULTS

Of 168 subjects included, 111 (66.1 %) attended at least one session of voice therapy. Patients diagnosed with primary hyperfunctional voice disorders had a significantly higher attendance rate than other groups. Attenders had higher self-ratings of severity and more positive "feelings about voice therapy" compared to non-attenders. Regression models found three significant predictors of therapy attendance: primary diagnosis of hyperfunctional voice disorder, self-rated severity, and "feelings about voice therapy."

CONCLUSION

In this cohort, patients with more positive feelings about voice therapy, higher self-rated severity, and a diagnosis of primary hyperfunctional voice disorder were more likely to attend voice therapy.

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

Purpose Previous studies have reported that voice therapy via telepractice is useful for patients with nodules and muscle tension dysphonia. Nevertheless, telepractice for elderly patients with voice disorders has not yet been investigated. We conducted this study to examine the hypothesis that voice therapy via telepractice is not inferior to conventional voice therapy. Method Eighty patients with dysphonia aged more than 55 years participated in this study from September 2016 to June 2018. After screening the inclusion and the exclusion criteria, 69 patients were randomized into telepractice (33 patients) and conventional (36 patients) groups. The outcome measurements included Voice Handicap Index-10, videolaryngostroboscopy, maximum phonation time, auditory-perceptual evaluation, and acoustic analysis. Paired t test, Wilcoxon signed-ranks test, and repeated measures analysis of variance were used to examine treatment outcomes. Results The diagnoses of voice disorders included atrophy (n = 33), unilateral vocal paralysis (n = 13), muscle tension dysphonia (n = 7), nodules (n = 6), and polyps (n = 10). No significant differences were observed in age, sex, and baseline measurements between the two groups. Twenty-five patients in the telepractice group and 24 patients in the control group completed at least four weekly sessions. Significant improvements were observed for all the outcome measures (p < .05) in both groups. Improvements in Voice Handicap Index-10 in the telepractice group (24.84 ± 5.49 to 16.80 ± 8.94) were comparable to those in the conventional group (22.17 ± 7.29 to 13.46 ± 9.95, p = .764). Other parameters also showed comparable improvements between the two groups without statistically significant differences. Conclusions This is the first randomized controlled trial comparing telepractice and conventional voice therapy in elderly patients with voice disorders. The results showed that the effectiveness of voice therapy via telepractice was not inferior to that of conventional voice therapy, indicating that telepractice can be used as an alternative to provide voice care for elderly patients with vocal disorders.

Predictors of Voice Therapy Initiation: A Cross-Sectional Cohort Study

OBJECTIVES/HYPOTHESIS

To determine predictors of voice therapy initiation.

STUDY DESIGN

Cross-sectional cohort study.

METHODS

All patients were evaluated in an interdisciplinary model at the University of Wisconsin Voice and Swallow Clinics between June 2016 and October 2017. Patients were eligible if they were diagnosed with a voice disorder and recommended for voice therapy as the only treatment. The dependent variable was attendance in at least once voice therapy session. Independent variables included therapeutic alliance, measured using the Session Rating Scale, and patient- and disease-related factors. These factors included gender, age, distance to the clinic, education level, household composition, occupational voice demand, Voice Handicap Index score, auditory-perceptual dysphonia severity (Grade, Roughness, Breathiness, Asthenia, Strain), and medical voice diagnosis.

RESULTS

Ninety-five patients were enrolled in the study. Voice therapy initiation rate was 70%. Having fewer school-aged children (5-18 years) in the household was significantly different between the group that initiated voice therapy and the group that did not (P = 0.048). There was no difference between groups for all other factors.

CONCLUSIONS

This investigation suggests that household composition, specifically having fewer school-aged children in the household, may predict initiation of voice therapy. This study confirms in a prospective fashion the absence of relationship between voice therapy initiation and most patient- and disease-related factors. Therapeutic alliance should be further investigated for its ability to predict voice therapy initiation using a measure that is validated for the population of patients with dysphonia.

Evaluation of Psychometric Properties of Voice Activity and Participation Profile (VAPP): A Spanish Version

OBJECTIVES

This study aimed to analyze the psychometric properties of the Spanish version of the Voice Activity and Participation Profile (SVAPP) questionnaire.

STUDY DESIGN

A randomized, cross-sectional sampling strategy with controls was used.

METHODS

Two samples with a total of 169 participants were analyzed, specifically 61 men (mean age 37.02) and 108 women (mean age 37.78). Of these participants, 112 were patients and 57 were controls. The instrument was submitted to reliability (internal consistency and corrected item-total correlations) and reproducibility analyses. Validation assessment was based on the construct validity, convergent validity, discriminant validity, and concurrent validity.

RESULTS

The global internal consistency was excellent (Cronbach's α = 0.976), corrected item-total correlations were satisfactory and ranged 0.63-0.89, and factor loadings were above 0.50. The different subscales showed good internal consistency (alpha coefficients ranged 0.830-0.956) and test-retest values were consistently associated. The exploratory factor analysis evidenced a strongly defined five factors internal structure, with factors loadings ranging 0.51-0.86. Convergent validity demonstrated that all subscales and scores were very strongly correlated (Pearson r above 0.735) and significantly associated. The discriminant validity analysis showed that SVAPP had good specificity to distinguish dysphonic from healthy voice subjects. Concurrent validity with Voice Handicap Index Spanish version (SVHI) showed very strong correlations between total scores, and between SVHI total score and SVAPP Daily and Social Communication subscales; correlations between both tests subscales were strong; only between SVAPP Work and SVHI Physical sections correlations were moderate.

CONCLUSIONS

The findings of the present study demonstrated evidence for the SVAPP questionnaire reliability and validity, and provided insightful implications of voice disorders on Spanish patients' quality of life. However, further investigations are required.

Multi-institutional Study of Voice Disorders and Voice Therapy Referral: Report from the CHEER Network

OBJECTIVES

To assess perspectives of patients with voice problems and identify factors associated with the likelihood of referral to voice therapy via the CHEER (Creating Healthcare Excellence through Education and Research) practice-based research network infrastructure.

STUDY DESIGN

Prospectively enrolled cross-sectional study of CHEER patients seen for a voice problem (dysphonia).

SETTING

The CHEER network of community and academic sites.

METHODS

Patient-reported demographic information, nature and severity of voice problems, clinical diagnoses, and proposed treatment plans were collected. The relationship between patient factors and voice therapy referral was investigated.

RESULTS

Patients (N = 249) were identified over 12 months from 10 sites comprising 30 otolaryngology physicians. The majority were women (68%) and white (82%). Most patients reported a recurrent voice problem (72%) and symptom duration >4 weeks (89%). The most commonly reported voice-related diagnoses were vocal strain, reflux, and benign vocal fold lesions. Sixty-seven percent of enrolled patients reported receiving a recommendation for voice therapy. After adjusting for sociodemographic and other factors, diagnoses including vocal strain/excessive tension and vocal fold paralysis and academic practice type were associated with increased likelihood of reporting a referral for voice therapy.

CONCLUSIONS

The CHEER network successfully enrolled a representative sample of patients with dysphonia. Common diagnoses were vocal strain, reflux, and benign vocal fold lesions; commonly reported treatment recommendations included speech/voice therapy and antireflux medication. Recommendation for speech/voice therapy was associated with academic practice type.

Factors Influencing Likelihood of Voice Therapy Attendance

Objective To identify factors associated with the likelihood of attending voice therapy among patients referred for it in the CHEER (Creating Healthcare Excellence through Education and Research) practice-based research network infrastructure. Study Design Prospectively enrolled cross-sectional study. Setting CHEER network of community and academic sites. Methods Data were collected on patient-reported demographics, voice-related diagnoses, voice-related handicap (Voice Handicap Index-10), likelihood of attending voice therapy (VT), and opinions on factors influencing likelihood of attending VT. The relationships between patient characteristics/opinions and likelihood of attending VT were investigated. Results A total of 170 patients with various voice-related diagnoses reported receiving a recommendation for VT. Of those, 85% indicated that they were likely to attend it, regardless of voice-related handicap severity. The most common factors influencing likelihood of VT attendance were insurance/copay, relief that it was not cancer, and travel. Those who were not likely to attend VT identified, as important factors, unclear potential improvement, not understanding the purpose of therapy, and concern that it would be too hard. In multivariate analysis, factors associated with greater likelihood of attending VT included shorter travel distance, age (40-59 years), and being seen in an academic practice. Conclusions Most patients reported plans to attend VT as recommended. Patients who intended to attend VT reported different considerations in their decision making from those who did not plan to attend. These findings may inform patient counseling and efforts to increase access to voice care.

Associação entre a adesão da terapia vocal e perfil de atividades vocais em pacientes disfônicos comportamentais

RESUMO Objetivo Analisar a associação entre a adesão da terapia vocal, perfil de atividades vocais em pacientes disfônicos comportamentais e seus possíveis fatores associados. Método Participaram da amostra dezoito indivíduos com disfonia comportamental que estavam em tratamento regular no Serviço de Fonoaudiologia da instituição. Os participantes do estudo responderam ao protocolo Perfil de Participação e Atividades Vocais (PPAV) e à escala URICA-VOZ. As variáveis associadas (número de sessões, faixa etária, tipo de disfonia comportamental, gênero e tratamento fonoaudiológico anterior) foram coletadas por meio de entrevista com o paciente e análise dos seus respectivos prontuários. Os dados foram submetidos à análise estatística inferencial. Resultados A maioria dos pacientes encontrava-se no estágio de ação. Houve associação estatisticamente significante entre o aspecto Efeitos na Emoção do PPAV e os estágios de prontidão para a adesão da terapia vocal, porém os outros aspectos do PPAV não se associaram com a escala URICA-VOZ. Das variáveis associadas, o número de sessões, faixa etária e tipo de disfonia comportamental apresentaram associação com a adesão da terapia de voz. Constatou-se diferença estatisticamente significante entre o tipo de disfonia comportamental e os escores do PPAV. Conclusão O aspecto Efeitos na Emoção do PPAV e as variáveis número de sessões, faixa etária e tipo de disfonia mostraram-se associadas ao estágio de adesão da escala URICA-VOZ. Os indivíduos com disfonia organofuncional apresentaram maior impacto da alteração vocal em suas atividades diárias.

Autoavaliação e prontidão para mudança em pacientes disfônicos

RESUMO Objetivo Analisar se existe associação entre a autoavaliação vocal e a prontidão para mudança em pacientes disfônicos. Método Participaram 151 pacientes com queixa vocal e diagnóstico de disfonia, entre 18 e 65 anos de idade, 47 homens e 104 mulheres, atendidos no ambulatório de voz de uma instituição pública. Foram aplicados quatro instrumentos de autoavaliação, incluindo o Questionário de Qualidade de Vida em Voz (QVV), o Índice de Desvantagem Vocal (IDV) e a Escala de Sintomas Vocais (ESV), além da utilização do instrumento URICA-VOZ, para verificação do estágio de prontidão para mudança dos pacientes. Todos os instrumentos foram aplicados imediatamente antes do início da terapia vocal. As variáveis foram correlacionadas e comparadas por meio de estatística inferencial. Resultados A maioria dos pacientes encontrava-se no estágio de contemplação (76,2%, n = 115), 22 (14,6%), no estágio de pré-contemplação e 14 (9,3%), no estágio de ação. Houve correlação negativa entre o escore no URICA-VOZ e o domínio socioemocional e escore total do QVV. Ocorreu correlação positiva entre o escore do URICA-VOZ e os domínios total, emocional e funcional do IDV, assim como entre o escore do URICA-VOZ e os domínios total, de limitação e emocional da ESV. Apenas os valores do domínio socioemocional do QVV e emocional no ESV apresentaram diferenças estatisticamente significantes entre os estágios motivacionais. Conclusões Existe associação entre a autoavaliação vocal e a prontidão para mudança em pacientes disfônicos. Pacientes com maior impacto na qualidade de vida em voz no QVV e maior frequência de sintomas vocais referida na ESV apresentam maior prontidão para mudança.

Predicting and influencing voice therapy adherence using social-cognitive factors and mobile video

PURPOSE

Patient adherence to voice therapy is an established challenge. The purpose of this study was (a) to examine whether adherence to treatment could be predicted from three social-cognitive factors measured at treatment onset: self-efficacy, goal commitment, and the therapeutic alliance, and (b) to test whether the provision of clinician, self-, and peer model mobile treatment videos on MP4 players would influence the same triad of social cognitive factors and the adherence behavior of patients.

METHOD

Forty adults with adducted hyperfunction with and without benign lesions were prospectively randomized to either 4 sessions of voice therapy enhanced by MP4 support or without MP4 support. Adherence between sessions was assessed through self-report. Social cognitive factors and voice outcomes were assessed at the beginning and end of therapy. Utility of MP4 support was assessed via interviews.

RESULTS

Self-efficacy and the therapeutic alliance predicted a significant amount of adherence variance. MP4 support significantly increased generalization, self-efficacy for generalization, and the therapeutic alliance. An interaction effect demonstrated that MP4 support was particularly effective for patients who started therapy with poor self-efficacy for generalization.

CONCLUSION

Adherence may be predicted and influenced via social-cognitive means. Mobile technology can extend therapy to extraclinical settings.

Analysis of aspects of quality of life in teachers' voice after discharged: longitudinal study

PURPOSE: To evaluate the long-term effects of voice therapy on the life quality of teachers who were discharged or abandoned the voice therapy for dysphonia. METHODS: This was a longitudinal study based on analysis of assessments with teachers of municipal schools in Belo Horizonte, who were referred to voice therapy and were discharged or abandoned the speech-language therapy for more than six months. A total of 33 teachers in the discharged group and 20 teachers in the abandoned group were contacted by phone and invited to participate in the study by answering the Voice activity and participation profile, which was forwarded to the researchers and sent via letter. RESULTS: At the moment of the pre speech therapy, the discharged and abandoned groups were homogeneous, except in relation to daily communication parameter. Comparing the discharged group in the pre and post speech-language therapy, it was showed improvements in social communication parameter as well as in the total score. The discharged group presented worsening in self-perception parameter when comparing the average values in the post therapy and current moments, and the group abandoned presented worsening in work, social communication and total score when comparing to the average values in the pre therapy and current moments. The discharged and abandoned groups differ in the present moment in all investigated parameters. CONCLUSION: Speech-language therapy for dysphonia have long term positive effects on life quality and voice of teachers who were soon discharged from the therapy and in a period of two years on average. Teachers who have abandoned treatment and did not obtain improvement in the voice showed negative impact in life quality and voice in a time of 2 years and 2 months on average.
