A Comparison of Voice Amplifiers and Personal Communication Systems for Hypophonia: An Exploration of Communicative Participation.

PURPOSE: The primary purpose of this study was to evaluate how individuals with hypophonia (HP; also referred to as HP participants) and their primary communication partners (PCPs; also referred to as PCP participants) rate communicative participation before and after experience with a speech amplification device. A secondary purpose was to evaluate pre- and post-device effects on self-rated communicative participation for each of the three speech amplification devices trialed outside of the laboratory. METHOD: Seventeen individuals with HP and their PCPs participated in a crossover design study that compared three different amplification devices: a wired belt-pack amplifier, a wireless stationary amplifier, and a personal frequency modulation (FM) system. Both the individuals with HP and their PCPs self-rated communicative participation at baseline and after trialing each device following 1-week device trial periods at home. Patient-reported outcome measures included the Communicative Effectiveness Survey (CES) and the Voice Activity and Participation Profile (VAPP). Following study completion, participants indicated whether they would like to select a specific device to continue using. RESULTS: Overall, HP participants rated communicative participation following device use higher than that in the pre-device condition, with the FM system resulting in the overall highest VAPP ratings and second highest CES ratings. Furthermore, HP and PCP participants rated these measures similarly. Finally, HP participants who selected a device to continue using self-reported lower total communicative effectiveness scores and greater voice activity limitations and participation restrictions at baseline in comparison to the nonselectors. CONCLUSIONS: This study contributes to an increased understanding of how communicative participation is experienced within this clinical population resulting from speech amplification. It is suggested that the inclusion of participation-based outcome measurement is essential to ensure a multidimensional and comprehensive approach to device prescription for individuals with HP.

Telehealth Assessments and Interventions for Individuals With Poststroke Aphasia: A Scoping Review.

PURPOSE: There are increasing demands for aphasia assessment and intervention services to be delivered remotely. The purpose of this scoping review was to address what is known about the delivery of assessments and interventions using telehealth for people with poststroke aphasia. Specifically, the review sought to (a) identify which telehealth assessment protocols have been used, (b) identify which telehealth intervention protocols have been used, and (c) describe evidence on the effectiveness and feasibility of telehealth for people with poststroke aphasia. METHOD: A scoping review of the literature published in English since 2013 was conducted by searching MEDLINE, Embase, PsycINFO, CINAHL, and Scopus databases to identify relevant studies. A total of 869 articles were identified. Two reviewers screened records independently, finding 25 articles eligible for inclusion. Data extraction was conducted once and validated by the second reviewer. RESULTS: Two of the included studies examined telehealth assessment protocols, whereas the remaining studies focused on the delivery of telehealth interventions. The results of the included studies illustrated both effectiveness and feasibility regarding telehealth for people with poststroke aphasia. However, a lack of procedural variation among the studies was found. CONCLUSIONS: Overall, this scoping review yielded continued support for the use of telehealth practices as an alternate mode of delivering both assessment and intervention services to people with poststroke aphasia. However, further research is needed to investigate the range of aphasia assessment and intervention protocols that can be offered via telehealth, such as assessments or interventions that use patient-reported measures or address extralinguistic cognitive abilities.

Communicative Participation in Dysarthria: Perspectives for Management.

Communicative participation is restricted in many conditions associated with dysarthria. This position paper defines and describes the construct of communicative participation. In it, the emergence of this construct is reviewed, along with the predictors of and variables associated with communicative participation in the dysarthrias. In doing so, the features that make communicative participation unique and distinct from other measures of dysarthria are highlighted, through emphasizing how communicative participation cannot be predicted solely from other components of the World Health Organization's International Classification of Functioning, Disability and Health (ICF), including levels of impairment or activity limitations. Next, the empirical literature related to the measurement of communicative participation and how this research relates to dysarthria management is presented. Finally, the development of robust clinical measures of communicative participation and approaches to management is described from the point of view of the clinician. We argue that communicative participation should be a primary focus of treatment planning and intervention to provide patient-centered, holistic, and value-based clinical interventions which are responsive to the needs of individuals living with dysarthria.

Speech Intensity Response to Altered Intensity Feedback in Individuals With Parkinson's Disease.

Purpose Hypophonia (low speech intensity) is the most common speech symptom experienced by individuals with Parkinson's disease (IWPD). Previous research suggests that, in IWPD, there may be abnormal integration of sensory information for motor production of speech intensity. In the current study, intensity of auditory feedback was systematically manipulated (altered in both positive and negative directions) during sensorimotor conditions that are known to modulate speech intensity in everyday contexts in order to better understand the role of auditory feedback for speech intensity regulation. Method Twenty-six IWPD and 24 neurologically healthy controls were asked to complete the following tasks: converse with the experimenter, start vowel production, and read sentences at a comfortable loudness, while hearing their own speech intensity randomly altered. Altered intensity feedback conditions included 5-, 10-, and 15-dB reductions and increases in the feedback intensity. Speech tasks were completed in no noise and in background noise. Results IWPD displayed a reduced response to the altered intensity feedback compared to control participants. This reduced response was most apparent when participants were speaking in background noise. Specific task-based differences in responses were observed such that the reduced response by IWPD was most pronounced during the conversation task. Conclusions The current study suggests that IWPD have abnormal processing of auditory information for speech intensity regulation, and this disruption particularly impacts their ability to regulate speech intensity in the context of speech tasks with clear communicative goals (i.e., conversational speech) and speaking in background noise.

Exploring the Psychosocial Impact of Botulinum Toxin Type A Injections for Individuals With Oromandibular Dystonia: A Qualitative Study of Patients' Experiences.

Purpose The purpose of this study was to explore the psychosocial impact of botulinum toxin (BoNT) injections for oromandibular dystonia (OMD) and to gain a better understanding of how participants judge the success of this treatment. Method Eight individuals with OMD and dysarthria participated in one face-to-face, semistructured interview. Interviews were audio-recorded and transcribed verbatim. Qualitative, phenomenological methods of coding, immersion, and emergence were used in the analysis of interview data. Results Two major themes and six subthemes emerged from the analysis of interview data. The first theme, Botox has changed me and my experiences, explored the participants' perspective of receiving BoNT injections and its psychosocial impact. The second theme, What communication is like for me, explored the psychosocial impact of BoNT on speech production and participation. Conclusions Our results suggest that BoNT has a variable impact on domains related to quality of life, satisfaction with treatment, speech production, and communicative participation. This study adds novel information related to the psychosocial consequences of BoNT treatment in the management of OMD and builds on a literature that studies the consequences and experiences of living with OMD.

Application of ICF conceptual framework in Osteoporosis.

Background: Osteoporosis (OP) is a metabolic bone disease defined by low bone strength and deterioration of bone tissue, which has wide clinical presentations. The World Health Organization's International Classification of Functioning Disability and Health (ICF) provides a common language, classification system, and conceptual framework to describe the consequences of health conditions in terms of body function and structure, activities and participation, environmental and personal factors. Objectives: The ICF conceptual framework was used, in this paper, to integrate OP research-based knowledge into clinical application using clinical vignettes. Results: Body functions and structures, activities and participation, environmental factors and personal factors are described, and the inter-connection among these factors is explored. The vignettes highlight the importance of different components of the ICF framework and to demonstrate how the ICF framework can capture individual differences in how disability can be experienced in OP. Conclusion: The ICF conceptual framework provides a holistic representation of disability by facilitating a critical appraisal of the health status of people with OP. The framework creates an awareness of the broad and multidimensional nature of OP on the health of individual patients, integrates dimensions of functioning, and highlights the complexity of the evaluation and management of OP.

The Consequences of Oromandibular Dystonia on Communicative Participation: A Qualitative Study of the Insider's Experiences.

Purpose The purpose of this study was to obtain a self-reported account of the experience of living with oromandibular dystonia (OMD) to gain a better understanding of both the daily facilitators and barriers to communicative participation and the strategies used for adapting to life with OMD. Method Eight individuals with OMD and dysarthria participated in 1 face-to-face, semistructured interview. Interviews were audio-recorded and transcribed verbatim. Qualitative, phenomenological methods of coding, immersion, and emergence were used in the analysis of interview data. Results Three major themes and 7 subthemes emerged from the analysis of interview data. First, "speaking is different now" provided examples of how speech changes are manifested in various life situations. Second, "my roles have changed" addressed how OMD has impacted work, home, and social roles. Third, "I accept it and move on" involved finding strategies that help and adopting a different perspective. Conclusion We suggest that the management of OMD must take a more holistic approach by addressing consequences beyond the physical symptoms and be tailored to each individual based on his or her personal concerns and goals.

Self-Rated Communication-Related Quality of Life of Individuals With Oromandibular Dystonia Receiving Botulinum Toxin Injections.

PURPOSE: In this preliminary study, we examined self-rated communication-related quality of life (CR-QoL) of 10 control participants and 10 individuals with oromandibular dystonia (OMD) and dysarthria receiving therapeutic botulinum toxin (BoNT-A) injections. METHOD: Participants with OMD and associated dysarthria self-rated CR-QoL pre- and post- BoNT-A injection using the American Speech-Language-Hearing Association's Quality of Communication Life Scale (ASHA QCL; Paul et al., 2004). Control participants self-rated CR-QoL during a single experimental visit. RESULTS: Significant differences were found between control participants and participants with OMD on ratings of CR-QoL across all 5 domains and subdomains of the ASHA QCL. No significant differences in CR-QoL were found over the course of the BoNT-A treatment cycle. CONCLUSIONS: CR-QoL was rated lower by participants with OMD as compared with control participants across all ASHA QCL domains/subdomains with "socialization/activities" and "confidence/self-concept" having the largest effect sizes. No differences in CR-QoL were found over the course of the treatment cycle. We advocate for outcome measures that include patient report. The use of patient-reported outcome measures in conjunction with objective or impairment-based outcome measures can help inform meaningful clinical indicators of treatment success. This study adds novel information that may aid our understanding of the experience of living with OMD in this underserviced clinical population.
