Instrumental Assessment Of Aero-Resistive Expiratory Muscle Strength Rehabilitation Devices, Angela M. Dietsch, Rahul Krishnamurthy, Kelsey Young, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Purpose

Expiratory muscle strength training (EMST) is increasingly being used to treat voice, cough, and swallowing deficits in a wide range of conditions. However, a multitude of aero-resistive EMST models are commercially available, and the ab-sence of side-by-side comparative data interferes with clinicians’ ability to assess which model is best suited to a particular client’s needs. The primary aim of this research was to test and compare the pressure and flow parameters of six currently available EMST models to help inform clinical decision making.

Method

We identified and tested five devices of each of six different EMST models to generate …

Relationships between novel phenotypic behaviors and specific genetic alterations are often discovered using target-specific, directed mutagenesis or phenotypic selection following chemical mutagenesis. An alternative approach is to exploit deficiencies in DNA repair pathways that maintain genetic integrity in response to spontaneously induced damage. Mice deficient in the DNA glycosylase NEIL1 show elevated spontaneous mutations, which arise from translesion DNA synthesis past oxidatively induced base damage. Several litters of Neil1 knockout mice included animals that were distinguished by their backwards-walking behavior in open-field environments, while maintaining frantic forward movements in their home cage environment. Other phenotypic manifestations included swim test failures, …


Comparing Taste Perception Across Modalities In Healthy Adults: Liquids Versus Dissolvable Taste Strips, Ross M. Westemeyer, Angela M. Dietsch Apr 2023

Comparing Taste Perception Across Modalities In Healthy Adults: Liquids Versus Dissolvable Taste Strips, Ross M. Westemeyer, Angela M. Dietsch

Department of Special Education and Communication Disorders: Faculty Publications

Taste stimulation has rehabilitative value in dysphagia management, as it activates salient underlying afferent pathways to swallowing which may evoke feedforward effects on swallow biomechanics. Despite its potential beneficial effects on swallow physiology, taste stimulation’s clinical application is limited for persons unsafe to orally consume food/liquid. This study aimed to create edible, dissolvable taste strips matched to flavor profiles previously used in research assessing taste’s effects on swallowing physiology and brain activity, and to evaluate how similar their perceived intensity and hedonic, or palatability, ratings were between their liquid counterparts. Plain, sour, sweet–sour, lemon, and orange flavor profiles were custom-made …

The purpose of this study was to examine the outdoor adventure experiences of youths with visual impairments participating in a week-long sports camp. Thirty-seven youths with visual impairment (ages 9–19 years) attending a one-week sports camp participated in this study. Participants engaged in a variety of outdoor adventure activities throughout the week of camp (e.g., sailing, hiking, rock climbing, biking, kayaking). Participants …


Inherent Envelope Fluctuations In Forward Masking: Effects Of Age And Hearing Loss, Marc A. Brennan, Adam Svec, Afagh Farhadi, Braden N. Maxwell, Laurel H. Carney Mar 2023

Inherent Envelope Fluctuations In Forward Masking: Effects Of Age And Hearing Loss, Marc A. Brennan, Adam Svec, Afagh Farhadi, Braden N. Maxwell, Laurel H. Carney

Department of Special Education and Communication Disorders: Faculty Publications

Forward masking is generally greater for Gaussian noise (GN) than for low-fluctuation noise maskers, i.e., GN disruption. Because the minimal hearing loss that is associated with older age may affect GN disruption differently than more significant hearing loss, the current study explored the contribution of minimal hearing loss associated with older age to GN disruption. GN disruption was measured using three masker-signal delays (25, 75, and 150 ms) for three adult groups: younger participants with normal hearing (NH), older participants with minimal hearing loss, and older participants with sensorineural hearing loss. The role of underlying mechanisms was tested using a …

Perspectives On Adaptive Functioning And Intellectual Functioning Measures For Intellectual Disabilities Behavioral Research, Laura J. Mattie, Susan J. Loveall, Marie Moore Channell, Derek B. Rodgers

Department of Special Education and Communication Disorders: Faculty Publications

Introduction: Intellectual disability (ID) is a significant limitation in both intellectual ability and adaptive functioning, but many studies of participants with ID only include a measure of overall intellectual functioning when describing their samples. The purpose of this perspective article was to provide a starting point for future research regarding the utility of including measures of both intellectual and adaptive functioning in research focused on ID. In this article, we discuss the differences and similarities between the constructs of intellectual and adaptive functioning, how they are measured, and the benefits of using both measures to describe participant abilities. Data …

Method

Modifications to the Rainbow Passage, a standardized paragraph utilized for eliciting speech samples in clinical settings, focused on nongendered terminology and the elimination of content with religious connotations.

Results

The recommended edits to the Rainbow Passage maintain similar length, cadence, and phonetic balance …


Investigating The Use Of Spread Of Excitation As A Measure Of Sensitivity To Interaural Asymmetry, Mona Jawad, Simin Soleimanifar, Michelle L. Hughes, Justin M. Aronoff Oct 2022

Investigating The Use Of Spread Of Excitation As A Measure Of Sensitivity To Interaural Asymmetry, Mona Jawad, Simin Soleimanifar, Michelle L. Hughes, Justin M. Aronoff

Department of Special Education and Communication Disorders: Faculty Publications

Interaural asymmetry decreases sensitivity to binaural cues such as interaural time differences (ITD) for bilateral cochlear implant users. However, the effects of interaural asymmetry may be mitigated for this population by the broad current spread typical of electrical stimulation. Current spread can be estimated using spread of excitation (SOE) functions. These measure the extent to which electrodes stimulate overlapping neural populations. This is done by measuring electrically evoked compound action potentials (eCAPs) in response to stimulating different masker electrodes. The goal of this study was to determine if SOE functions can predict the effect of interaural asymmetry on cochlear implant …

Department of Special Education and Communication Disorders: Faculty Publications

The prevalence of autism spectrum disorder (ASD) has risen significantly in the past two decades. Unfortunately, there is a shortage of mental health providers who have specialized training in delivering evidenced-based services to this population. Early intensive behavioral intervention (EIBI) is an evidenced-based treatment recommended for toddlers with ASD, and school psychologists are uniquely positioned to help children with ASD receive it. However, many school psychologists do not receive adequate training in this subspecialty. This paper makes recommendations to school psychology training programs about how to add or improve training in this subspecialty based on the results of an Office …

Function Of Bidirectional Sensitivity In The Otolith Organs Established By Transcription Factor Emx2, Young Rae Ji, Yosuke Tona, Talah Wafa, Matthew E. Christman, Edward D. Tourney, Tao Jiang, Sho Ohta, Hui Cheng, Tracy Fitzgerald, Bernd Fritzsch, Sherri M. Jones, Kathleen E. Cullen, Doris K. Wu

Department of Special Education and Communication Disorders: Faculty Publications

Otolith organs of the inner ear are innervated by two parallel afferent projections to the brainstem and cerebellum. These innervations were proposed to segregate across the line of polarity reversal (LPR) within each otolith organ, which divides the organ into two regions of hair cells (HC) with opposite stereociliary orientation. The relationship and functional significance of these anatomical features are not known.Here, we show regional expression of Emx2 in otolith organs, which establishes LPR, mediates the neuronal segregation across LPR and constitutes the bidirectional sensitivity function. Conditional knockout (cKO) of Emx2 in HCs lacks LPR. Tmie cKO, in which mechanotransduction …

Students’ Self-Efficacy In Self-Regulation Together With Behavioural And Emotional Strengths: Investigating Their Self-Perceptions, Minna Ikävalko, Erkko Sointu, Matthew C. Lambert, Jaana Viljaranta

Department of Special Education and Communication Disorders: Faculty Publications

Students’ self-perceptions are a foundation for educational and psychosocial development. In order to investigate self-perceptions, we need to recognise the preconceptions (e.g. doubts and confidence) students hold about themselves. In this study, we examined 10–16-year-old students’ (N=599) self–perceptions from the viewpoints of the sources of self-efficacy in self-regulation and behavioural and emotional strengths. Specifically, we used descriptive analyses to examine whether students’ ages or received pedagogical support played a role in how they perceived themselves, and whether these viewpoints are related to each other. Our results indicate that, in general, primary school students perceived their sources of self-efficacy in self-regulation …

Provide data on the five characteristics of emotional disturbance (ED). For 503 students with ED and 2016 without disabilities, teachers rated the characteristics (Inability to Learn; Relationship Problems; Inappropriate Behavior; Unhappiness or Depression; Physical Symptoms or Fears), plus Socially Maladjusted. We applied a 2 (ED, without disabilities) × 2 (female, male) × 3 (elementary, middle, high school) covariance analysis, with follow‐up comparisons. Students with ED showed greater problems than students without disabilities on all five characteristics, and Socially Maladjusted. On Inability to Learn, among students with ED genders did not differ at elementary but males …


Inclusion Of Individuals With Neurodevelopmental Disorders In Norm-Referenced Language Assessments, Susan J. Loveall, Marie Moore Channell, Laura J. Mattie, Alexandria E. Barkhimer Aug 2022

Inclusion Of Individuals With Neurodevelopmental Disorders In Norm-Referenced Language Assessments, Susan J. Loveall, Marie Moore Channell, Laura J. Mattie, Alexandria E. Barkhimer

Department of Special Education and Communication Disorders: Faculty Publications

Standardized, norm-referenced language assessment tools are used for a variety of purposes, including in education, clinical practice, and research. Unfortunately, normreferenced language assessment tools can demonstrate floor effects (i.e., a large percentage of individuals scoring at or near the lowest limit of the assessment tool) when used with some groups with neurodevelopmental disorders (NDDs), such as individuals with intellectual disability and neurogenetic syndromes. Without variability at the lower end of these assessment tools, professionals cannot accurately measure language strengths and difficulties within or across individuals. This lack of variability may be tied to poor representation of individuals with NDDs in …

Assessing Pre-Literacy Behaviors In Infants And Toddlers: Psychometric Evaluation Of The Infant Toddler Literacy Assessment (Itla-3), Barbara J. Jackson, Christine Marvin, Amy J. Encinger, Nicole Buchholz, Becky Zessin

Department of Special Education and Communication Disorders: Faculty Publications

Assessment of emerging literacy in young children is generally limited to either skill development in children over 3 years of age or the quality and context of young children’s early literacy experiences. Although there has been promotion of their early literacy experiences, assessment of emerging pre-literacy behaviors in children younger than 3 years has yet to be organized into a single tool.

Preliminary work on the Infant Toddler Literacy Assessment (ITLA) has progressed through initial steps of scale development and shown promise as a criterionbased, standardized assessment for tracking children’s pre-literacy behaviors and guiding practitioners in supporting development of those …

Department of Special Education and Communication Disorders: Faculty Publications

The effective connectivity of neuronal networks during orofacial pneumotactile stimulation with different velocities is still unknown. The present study aims to characterize the effectivity connectivity elicited by three different saltatory velocities (5, 25, and 65 cm/s) over the lower face using dynamic causal modeling on functional magnetic resonance imaging data of twenty neurotypical adults. Our results revealed the contralateral SI and SII as the most likely sources of the driving inputs within the sensorimotor network for the pneumotactile stimuli, suggesting parallel processing of the orofacial pneumotactile stimuli. The 25 cm/s pneumotactile stimuli modulated forward interhemispheric connection from the contralateral SII …

Department of Special Education and Communication Disorders: Faculty Publications

The stereocilia rootlet is a key structure in vertebrate hair cells, anchoring stereocilia firmly into the cell’s cuticular plate and protecting them from overstimulation. Using superresolution microscopy, we show that the ankyrin-repeat protein ANKRD24 concentrates at the stereocilia insertion point, forming a ring at the junction between the lower and upper rootlets. Annular ANKRD24 continues into the lower rootlet, where it surrounds and binds TRIOBP-5, which itself bundles rootlet F-actin. TRIOBP-5 is mislocalized in Ankrd24KO/KO hair cells, and ANKRD24 no longer localizes with rootlets in mice lacking TRIOBP-5; exogenous DsRed–TRIOBP-5 restores endogenous ANKRD24 to rootlets in these mice. Ankrd24 …

Department of Special Education and Communication Disorders: Faculty Publications

Current BCI-AAC systems largely utilize custom-made software and displays that may be unfamiliar to AAC stakeholders. Further, there is limited information available exploring the heterogenous profiles of individuals who may use BCI-AAC. Therefore, in this study, we aimed to evaluate how individuals with amyotrophic lateral sclerosis (ALS) learned to control a motor-based BCI switch in a row-column AAC scanning pattern, and person-centered factors associated with BCI-AAC performance. Four individuals with ALS completed 12 BCI-AAC training sessions, and three individuals without neurological impairment completed 3 BCI-AAC training sessions. To assess person-centered factors associated with BCI-AAC performance, participants completed both initial and …


Interpretation Of Ambiguous Pronouns In Adults With Intellectual Disabilities, Kara Hawthorne, Susan J. Loveall Feb 2021

Interpretation Of Ambiguous Pronouns In Adults With Intellectual Disabilities, Kara Hawthorne, Susan J. Loveall

Department of Special Education and Communication Disorders: Faculty Publications

Background — Pronouns are referentially ambiguous (e.g. she could refer to any female), yet they are common in everyday conversations. Individuals with typical development (TD) employ several strategies to avoid pronoun interpretation errors, including the subject bias — an assumption that a pronoun typically refers to the subject (or, with the closely related order-of-mention bias, the first-mentioned character) of the previous sentence. However, it is unknown if adults with intellectual disability (ID) share this strategy or the extent to which the subject bias is associated with non-verbal abilities or receptive vocabulary.

Methods — We tested 22 adults with mixed-aetiology ID …

Finding A Voice For Individuals With Asd Who Are Minimally Verbal Through Comprehensive Communication Assessment, Shelley Lund, Kristy Weissling, Wendy Quach, Miechelle L. Mckelvey

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Many, but not all, children with autism spectrum disorder (ASD) have a difficult time communicating in conventional ways to express their decisions, preferences, and ideas. Augmentative and alternative communication (AAC) can fulfill many purposes of communication and support a child to achieve maximal self-determination and agency. The goal of assessment is not to fit the child to a particular device or communication strategy—but rather to identify the strategies that enhance the child’s strengths to maximize their independent communication and ultimately their ability to exert control over their world.

Method: Our method was to combine results from our scoping review …
