Summary: For people experiencing dizziness, what are possible options for vestibular and balance rehabilitation? This self-study from Perspectives of the ASHA Special Interest Groups (SIG 7) addresses treatment choices in vestibular and balance rehabilitation, the state of the evidence on their efficacy, and future directions for interdisciplinary research and practice. Written by clinicians and scholars with expertise in audiology and physical therapy, the four articles present an interdisciplinary and life span approach to vestibular and balance rehabilitation for children and adults. The first article by Christy is on the use of vestibular and balance rehabilitation therapy for dizziness in children. Next, the review by Herdman focuses on the evolution of vestibular function tests and rehabilitation for major vestibular disorders as well as areas in which research and clinical practice may grow in the future. In Holmberg, the relatively new but common diagnosis of persistent postural-perceptual dizziness (PPPD) is presented in terms of its pathophysiology, differential diagnosis, and treatment protocols. Finally, Clendaniel provides a review on the use of vestibular rehabilitation in the treatment of benign paroxysmal positional vertigo. Included are detailed photos and illustrations of current techniques and exercises. As described in the introduction to the forum by Guest Editor Neil Shepard, PhD, “It is hoped that these four articles will provide a needed look at vestibular and balance rehabilitation therapy (VBRT) so the audiologist can serve as a productive member of the treatment team and have a good understanding as to everything that

Summary: This Perspectives (SIG 19) includes four different speech science articles that focus on speech production, speech perception, or both. Akbari and Aoyama examine epenthetic vowels produced by Persian L2 speakers of English corroborating previous research findings regarding acoustical characteristics of anaptyctic epenthetic vowels—prothetic epenthetic vowels differ from the phonemic vowels they precede. Hitchcock et al. examine speech perception of typical adults, typical children, and children with speech sound disorders, finding that children with speech sound disorders differ as compared to both typical groups. Rong conducted a preliminary examination of the articulatory control of speech and speech-like tasks. The results revealed shared and task-specific articulatory features in speech and speech-like tasks, specifically sharing that alternating motion rate tasks may be more useful for assessing temporal aspects of articulation whereas sequential motion rate tasks may be more useful for assessing spatial aspects of articulation and coordination. Lastly, Boyd-Pratt and Donai review evidence that the high frequency region contains perceptual cues regarding segmental, speaker identity, and speaker sex as well as improved speech recognition in the presence of noise.

Summary: These Perspectives (SIG 19) articles focus on perceptual considerations and the use of a system to investigate lingual coordination as a clinical tool. In the first article Rakerd et al. review the resonant effects of performers, resonance associated with nasality, and resonant voice for both normal and disordered populations. In the second article Grover et al. use the bubble noise method, which places noise randomly in time and frequency with “holes” or “bubbles” that give glimpses into the target signal, to determine what is perceptually important in the speech signal for native/first language listeners versus nonnative/second language listeners. In the final article, Dugan et al. review TonguePART, an image processing system used to track the tongue surface, as a reliable, fast method to track articulatory movement of the tongue for syllables

Summary: This activity presents a diverse perspective, including four different speech science articles focused on a variety of topics. Kimball and Sayce discuss the pros and cons of research using behavior and functional assessment and treatment in the areas of speech science and voice, specifically their limitation in outlining etiology or explaining treatment resistance. They also provide an overview of genetic research approaches as a possible path forward to develop additional evidence-based treatment approaches. Neel reviews the production and perception of extralinguistic information regarding sex/gender, sexual orientation, age, non-native accent, regional and social dialect, and race and ethnicity. The article explores the literature in the above areas reviewing acoustical features and common misperceptions, concluding with instructional activities to enhance student awareness of indexical characteristics. McAllister et al. studied the effects of biofeedback for residual rhotic errors in a preliminary case series. Participants were five native English speakers who had not yet generalized rhotic production. Treatment consisted of either electropalatographic or visual-acoustic biofeedback using the Challenge Point Program software. Although participant responses to treatment were variable, the median effect size tended to exceed the minimum value considered clinically significant. Gritsyk et al. examined three measures to determine which best predicted change in production accuracy during a vowel learning task. Using 20 female college students, researchers administered three tasks: an oral stereognosis task, a bite block task using auditory making, and a new phonetic awareness task. The bite block task with auditory masking, measuring proprioceptive awareness, was the only task significantly related to performance in speech learning.

Summary: How can audiologists enhance patient-centered communication, even during the COVID-19 pandemic? This self-study is from the journal, Perspectives of the ASHA Special Interest Groups, SIG 7: Auditory Rehabilitation and Its Instrumentation. It features two articles focused on patient-centered strategies for effective communication, from initial consultations to prioritizing follow-up care, during COVID-19. It also includes the article that won the 2021 ASHA Journals Editor’s Award for Perspectives (for SIGs 6, 7, 8, and 9) by Davidson and Marrone. The first article is, “How to Provide Accessible Hearing Health Information to Promote Patient-Centered Care.” Kelly-Campbell and Manchaiah review the literature within audiology on patient-provider communication. They focus on research studies of communication during initial audiology consultation sessions. Through a summary of themes in the literature, they categorize important research findings that provide insight into communication between patients and their audiologists. Finally, they identify five key strategies for effective patient-centered communication. Each strategy is then reviewed in detail, with clinical examples and specific recommendations that can be immediately implemented in practice. The second article is, “A Clinically Valuable Interaction in the Midst of COVID-19 and Beyond: A Viewpoint on the Importance of Patient-Centered Outcomes in Rehabilitative Audiology.” Davidson and Marrone discuss patient-centered communication following hearing aid device fittings. They identify challenges facing patients and audiologists related to follow-up hearing aid services as a result of the COVID-19 pandemic. Based on a literature review and their own recent research, they developed a decision-tree algorithm to help audiologists prioritize clinical activities following hearing aid fittings, including remote formats for care. The algorithm was based on use of a patient-centered outcome measure, the Measure of Audiologic Rehabilitation Self-Efficacy. Patient-centered outcomes measurement is suggested as an engagement strategy for continued communication with patients during the COVID-19 pandemic and beyond.
