Purpose: The primary purpose of this study was to evaluate the effect of three different types of speech amplification devices on spontaneous speech intelligibility of people with hypophonia secondary to Parkinson's disease or parkinsonism. Method: Twenty-one individuals with hypophonia described pictures aloud to their primary communication partner in four device and two noise conditions. Device conditions included no device, a portable wired speech amplifier, a wireless stationary amplifier, and a one-way personal communication system. Noise conditions included quiet and 65-dB multitalker background noise. Speech intelligibility was evaluated from the perspective of two listener groups, familiar communication partners and naive listeners, as a function of device type and noise. Results: Overall, all three devices were associated with improved intelligibility, especially in noise and for longer utterances for both listener groups. Intelligibility was highest for the personal communication system and lowest for the portable wired amplifier. These results for spontaneous speech patterned similarly to those for read sentences reported for these same talkers and listeners in Knowles et al. (2020) . Conclusions: Speech amplification devices demonstrate measurable improvements in intelligibility of spontaneous speech in individuals with hypophonia. Findings add to a growing body of evidence of the potential effectiveness of speech amplification as a management tool for hypophonia. Supplemental Material: https://doi.org/10.23641/asha.31834960

Purpose: This exploratory study evaluated the test–retest stability of three participation-based patient-reported outcome measures (PROMs) rated by individuals with Parkinson's disease (IWPD), primary communication partners (PCPs) serving as proxy raters, and control participants over three study visits spanning approximately 1 month. Method: Twenty-three IWPD and hypophonia, 23 PCPs, and 30 control participants attended three non-intervention experimental visits. During each visit, all participants completed three participation-based PROMs: Communicative Participation Item Bank (CPIB), Voice Activity and Participation Profile (VAPP), and Levels of Speech Usage Scale (LSUS). Proxy ratings for each PROM were completed by PCPs. Results: Results indicated significant differences between IWPD and control participants on all PROMs. IWPD exhibited lower scores on the CPIB and LSUS and higher scores on the VAPP compared to control participants. There was relative agreement in ratings between IWPD and their PCPs on all PROMs. Finally, there were relatively stable test–retest scores on all three PROMs over the three study visits, both within and between IWPD and PCPs. An exception was a statistically, but not clinically significant, decrease in CPIB scores between Visit 1 and Visit 3 for IWPD. Conclusions: This study has contributed to our understanding of the measurement properties of the CPIB, VAPP, and LSUS related to the test–retest stability of these measures over three time points in IWPD, proxy raters, and control participants. These findings provide additional context in the interpretation of participation-based PROMs in this clinical population and may prove to be useful in interpreting changes to participation-based PROM scores.

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.

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 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.

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.

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.

Purpose: This study compared the performance of three amplification devices hypothesized to improve speech communication in individuals with hypophonia (HP), as well as to identify individuals' device preferences.Method: Twenty-two individuals with HP and their primary communication partners participated in a cross-over design study comparing three different speech amplification devices: a wired portable amplifier (Device A), a wireless stationary amplifier (Device B), and a one-way personal communication system (Device C). Participants attended one laboratory visit followed by 1-week trial periods with each device. At the first visit, HP participants completed speech tasks with and without the devices, in quiet and in noise. Following the in-laboratory test period, participants trialed each device at home for approximately 1 week per device. Following completion of the study, participants indicated whether or not they would like to continue using a device.Results: Overall, in the presence of noise, all three devices demonstrated significant improvements in speech-to-noise levels and speech intelligibility compared to no device. A clear device hierarchy emerged such that the personal communication device (Device C) was associated with significantly better speech outcomes compared to the other two devices. The majority of participants elected to continue using a device at the completion of the study. Device preferences, however, did not clearly reflect the objective device hierarchy that was found for the objective speech measures. Each of the three devices was selected as a preferred device by at least three participants at the completion of the study.Conclusion: Results from this study demonstrated clear differences in device performance in three distinct forms of amplification devices for individuals with HP. Findings suggest that amplification device use may be beneficial for this clinical population and underscore the potential to improve device availability and device selection criteria in future research.Supplemental Material: https://doi.org/10.23641/asha.12735875

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.

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.
