Effect Of Head Coverings On Directional Microphone Performance In Modern Hearing Aids: A Kemar-Based Laboratory Evaluation, Zahra Fekri, Mariam Mohamad, Ayasakanta Rout

Faculty Scholarship

Background/Objectives: Directional microphones are an established hearing aid technology for improving speech understanding in background noise. Although researchers have examined the influence of hair, spectacles, and earmold venting on directional performance, no systematic work has addressed head coverings, which people wear worldwide for cultural, religious, occupational, and personal reasons. This study determined whether a cotton head covering alters the directivity index (DI) of highest-level receiver-in-canal (RIC) hearing aids. Methods: A Knowles Electronics Manikin for Acoustic Research (KEMAR) was positioned in a double-walled, sound-treated booth, and DI was measured for omnidirectional and fixed directional microphone settings, with and without a two-layer …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan

MEDI 9331 Scholarly Activities Clinical Years

Approximately 2% of DHH people in need of mental health services actually receive these services. Among pediatric hearing loss populations, co-occurring cognitive and physical impairments are risk factors for poor mental health status. Due to language barriers and isolation, more children with hearing loss do not have access to mental health services. Cochlear implants have been shown to improve mental health status among the DHH population. Current literature focuses on the mental health status of children with cochlear implants, with little focus on hearing aid users. Using HEAR28 data and surveys, we can quantify the incidence of psychiatric symptoms among …

Interprofessional Collaboration In Inpatient Rehabilitation For Patient With Thiamine Deficiency-Related Sensorimotor And Cognitive Deficits – Case Report, Christina Thomas, Tahreem Hashmi, Joanne Delgado-Lebron, Rania Massad

Journal of Interprofessional Practice and Collaboration

Purpose: We aim to describe the clinical presentation, interprofessional management, and functional outcomes of a patient with thiamine deficiency. Problem: Thiamine deficiency can result in peripheral polyneuropathy and cognitive deficits that limit function and participation. Despite deficits that warrant interprofessional neurorehabilitation, previous reports focus narrowly on medical management. Case: A 36-year-old female was admitted to inpatient rehabilitation with a diagnosis of Guillain Barre. She underwent evaluation by the interprofessional team that revealed cognitive deficits inconsistent with Guillain Barre. Further medical workup identified a thiamine deficiency. Comprehensive treatment included supplementation managed by the physiatrist; promotion of motor learning and neuroplasticity to …

Exploring The Impact Of Age On Traumatic Brain Injury Cause And Recovery In Arkansas: A Retrospective Review, Abby Jones, Steven Wheeler, Jessica Danley

2026 Honors Symposium

Traumatic brain injuries (TBIs) remain a major public health concern, and increasing evidence goes to show the significance of the effect of age in quality of care, diagnosis, and recovery outcomes. In rural states, such as Arkansas, where research has shown a lack of resources and higher fatality rates among TBI patients, healthcare professionals can become better informed and equipped as a result of research efforts to uncover the effects of age on cause and recovery for inpatient TBI individuals in the early stages (Daugherty et al., 2022). Current research and prior evidence suggests that older individuals are more likely …

Dual-Task Interaction Between Vestibular Function And Cognitive Processing Using The P300 Event-Related Potential, Laurel Elise Money-Nolan

Graduate Theses and Dissertations (2019 - present)

Previous research has established links between vestibular function and cognitive processing, aging and cognitive function, and aging and vestibular function. Theories of cognitive resource allocation discuss how cognitive resources, such as attention, are devoted towards and divided between tasks when multitasking. This dual-task study, utilizing a balance task and a listening/cognitive task, across the young- and middle-aged adult age range, aimed to evaluate potential relationships between vestibular function, cognition, and age, and to examine how cognitive resources might be allocated under dual-task conditions.

The dual-task protocol in this study utilized an oddball paradigm with tonal stimuli to measure the P300 …

Vestibular Migraine And Ssri Withdrawal: A Case Report, Grace Fairchild, Sarah Redding, Ashley G. Flagge

Ashley Flagge Publications

Vestibular migraine (VM) has been described as a diagnosis of exclusion, with no one singular definitive assessment for diagnosis. It has been suggested that possible pharmaceutical intervention for VM can include antidepressant drugs, but this is potentially complicated by the fact that dizziness is a common side effect of both use and withdrawal for certain types of antidepressant medications. This article describes the case of a 56-year old with probable VM, who was previously diagnosed with depression and treated with the selective serotonin reuptake inhibitor (SSRI) Citalopram. Following discontinuation with no taper, the patient experienced a series of withdrawal side …

Educating Future Nurse Practitioners And Physician Associates On Pretreatment Of Swallowing In Head And Neck Cancer, Hannah M. Berk, Erin L. O'Bryan, Imran Musaji, Carly A. Thomas, Jamie Harrington

Teaching and Learning in Communication Sciences & Disorders

Head and neck cancer treatment frequently results in long-term severe swallowing deficits, often requiring feeding tube dependency. Patients who have completed swallowing exercise programs before and during cancer treatment experienced more positive swallowing outcomes, but most patients are not referred for swallowing intervention early enough in their care to prevent long-term deficits. This student research project aimed to measure health profession students’ knowledge of swallowing pretreatment for head and neck cancer patients and to investigate the impact of an educational module developed and presented by a Communication Sciences and Disorders graduate student to improve knowledge and awareness of this clinical …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Educational Services And Language Congruency In Low-Income Children Who Are Deaf Of Hard-Of-Hearing, Courtney J. Austin, Dylan Chan, Jihyun Stephans

Research Colloquium

Background: Children who are deaf or hard-of-hearing (DHH) are required by United States law to have access to educational services through the Individuals with Disabilities in Education Act (IDEA). However, access to language-congruent providers, as well as supplemental services, varies considerably. Household income is associated with poorer hearing care access and outcomes in DHH children. We predict that access to supplemental, language-congruent DHH services is poorer in DHH children from lower-income homes.

Methods: This is a secondary, ad hoc exploratory study of DHH children aged 0-27 months enrolled in a randomized clinical trial (CT.gov: NCT04928209). Children were enrolled across all …

Neuroanatomical And Morphometric Differences In Children Who Stutter, Mohammad A. Khan

Honors Scholar Theses

Childhood-Onset Fluency Disorder commonly known as stuttering is a neurodevelopmental speech disorder characterized by disruptions in speech fluency. While genetic and neurobiological factors are implicated, the structural brain differences underlying stuttering remain unclear. This study investigated neuroanatomical alterations in children who stutter (CWS) compared to typically fluent children (TFC), focusing on gray matter volume, cortical thickness, and surface area in speech-related regions; the Inferior Frontal Gyrus, Middle Temporal Gyrus, and Pre-motor Operculum. High-resolution MRI data from 100 children (48 CWS, 52 TFC) aged 3–12 years were analyzed using FreeSurfer. Group comparisons revealed no statistically significant differences in cortical thickness, surface …

Intertrial Coherence As A Measure Of Synchrony In Ocular Vestibular Evoked Myogenic Potentials And The Effect Of Gaze Angle, Sydney Brown

Dissertations, 2020-current

Ocular vestibular evoked myogenic potentials (oVEMPs) are produced by highly synchronous bursts of extraocular muscle activity in response to stimuli. These responses reflect utricular function and can be recorded using surface electromyography electrodes. Traditional analysis of oVEMPs is limited to time-domain waveform measurements, such as amplitude and latency of response peaks. Objective synchrony-based measures have not yet been applied to the analysis of oVEMPs, particularly in the comparison of synchrony across gaze angles. We followed the new time-frequency method of analysis developed by Clinard et al. (2022) that was successfully applied to cervical VEMPs to quantify response synchrony. Air-conducted oVEMPs …

Adherence To Follow-Up Among High-Risk Nicu Patients, Iryna Muryn, Susan Mbullah Ndimah, Lisa Renee Eiland, Tara Lozy

Rowan-Virtua Research Day

Background:

Preterm infants, especially those ≤32 weeks' gestational age (GA) are at increased risk of vision and hearing loss. Risks of both vision and hearing loss can be ameliorated and in some cases prevented by conscientious screening, follow up and treatment. Universally, infants ≤32 weeks are cared for in neonatal intensive care units and there is considerable confidence that screenings and treatment occur according to established guidelines. At hospital discharge, follow up responsibility shifts to infant caretakers likely resulting in reduced compliance.

Objective:

We aimed to determine if preterm infants at risk for vision and hearing loss, attended follow up …

Aging-Related Hearing Decline And Resting State Networks, Cassidy S. T. Ellsworth

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study investigated the effects of age-related hearing decline on functional networks using resting-state functional magnetic resonance imaging (rs-fMRI). The main objective of the present study was to examine resting-state functional connectivity (rsFC) and graph theory-based network efficiency metrics in forty-nine adults categorized by age and hearing thresholds to identify the neural mechanisms of age-related hearing decline. RsFC within key brain networks and auditory-related brain regions, including the default mode network, salience network, dorsal attention network, and primary auditory cortices, was assessed using region-of-interest (ROI)-based and graph theory approaches. Functional metrics, such as rsFC strength and global and local efficiency, …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

Practice Patterns In Pediatric And Adult Dysphagia: Implications For Clinical Training, Jane Grothaus, Kaitlyn Hill, Marlee Nebesniak, Anastasia Raymer

Speech-Language Pathology Faculty Publications

Objective: Most speech language pathologists (SLPs) receive training to work with patients with swallowing disorders in graduate school, focusing primarily on adult dysphagia. Although SLPs share common foundational knowledge and skills for adult and pediatric dysphagia populations, there are considerable differences in these two specialized areas of practice. We aimed to query SLPs’ practice patterns for dysphagia assessment and management for adults and pediatric populations to consider differences and guide training efforts.

Methods: We distributed two comprehensive anonymous surveys to explore practice patterns of SLPs who provide assessment and management of dysphagia for adult or pediatric populations. The 118 respondents, …

An Observational Study Of Discourse Tasks And Running Speech Sampling In The Assessment Of Paediatric Voice Quality, Victoria Reynolds, Kristin Scavo-Smith, Kate Oteng-Bediako, Sophie Scanlon

Speech-Language Pathology Faculty Publications

Introduction

Running speech sampling is an essential component of a paediatric voice evaluation, in that it should provide the examiner with a representative vocal sample of the child's everyday voice use outside of the clinic setting. Current speech sampling practices, consisting of reading tasks, informal conversation sampling and the voice question ('Tell me about your voice problem'), may not elicit consistent samples or samples of sufficient length to allow the examiner to make a reliable and valid judgement about vocal quality. The aim of this study is to compare the voice quality of children produced in response to existing running …

A Comparison Of Vestibular Function In Young Adult Musicians And Non-Musician Peers, Alexandria W. Greene, Ashley G. Flagge, Nicholas S. Stanley

Ashley Flagge Publications

Purpose: The majority of college-level musicians exceed the daily recommended noise dose level during instrumental practices and performances, although less than one-third report wearing hearing protection while playing their instruments. Although the hazardous effects of music on the auditory system have been established, even in young adult musicians still early in their musical careers, the effects of music on the vestibular system are still unclear. The purpose of the present study was to examine vestibular/balance differences between young adult musicians and non-musicians to determine the effects of music exposure on the vestibular system.

Method: Young adult participants aged 18-27 years …

Diagnostic Overshadowing: A Delayed Diagnosis Of Autism Spectrum Disorder In A Deaf Child, Quynh-Chi Dang, Michael Hoffman, Rachel St. John

Journal of Early Hearing Detection and Intervention

Diagnostic overshadowing occurs when a patient with a pre-existing diagnosis presents with symptoms that are attributed to the diagnosis, but actually reflect a separate issue. This diagnostic overshadowing can lead to delays in diagnosis, as well as disparities in health care and outcomes. The following case will provide an example in which diagnostic overshadowing contributed to the delay of an autism diagnosis in a child who is deaf. With at least 40 to 50% of children who are deaf or hard of hearing having at least one co-existing medical/developmental condition, and the current prevalence of autism at 1 in 36 …

Oral Feeding Of Infants Who Require Noninvasive Respiratory Support: Retrospective Investigations, Carolyn Barnes

MUSC Theses and Dissertations

There is a dearth of evidence supporting the safety and efficacy of orally feeding infants who require noninvasive respiratory support (NIRS). This dissertation investigates clinical practices surrounding orally feeding infants on NIRS. Manuscript 1 systematically reviews parameters impacting study of this practice. Findings emphasize the dearth of objective data surrounding this practice, and that additional research must be conducted before safety and efficacy outcomes of this practice can be established. Manuscript 2 retrospectively uses electronic health record data to describe which infant populations are orally fed during NIRS use, amount of NIRS used during infant oral feeding, changes in practice …

Toward Generalizable Machine Learning Models In Speech, Language, And Hearing Sciences: Estimating Sample Size And Reducing Overfitting, Hamzeh Ghasemzadeh, Robert E Hillman, Daryush D Mehta

Faculty, Staff and Student Publications

PURPOSE: Many studies using machine learning (ML) in speech, language, and hearing sciences rely upon cross-validations with single data splitting. This study's first purpose is to provide quantitative evidence that would incentivize researchers to instead use the more robust data splitting method of nested

METHOD: First, the significant impact of different cross-validations on ML outcomes was demonstrated using real-world clinical data. Then, Monte Carlo simulations were used to quantify the interactions among the employed cross-validation method, the discriminative power of features, the dimensionality of the feature space, the dimensionality of the model, and the sample size. Four different cross-validation methods …

Rehabilitation Treatment Specification System For Voice Therapy: Application To Everyday Clinical Care, Jeremy Wolfberg, John Whyte, Patricia Doyle, Shirley Gherson, Jason Muise, Brian Petty, Carol Jorgensen Tolejano, Robert E Hillman, Tara Stadelman-Cohen, Jarrad H Van Stan

Faculty, Staff and Student Publications

PURPOSE: Rehabilitation intervention descriptions often do not explicitly identify active ingredients or how those ingredients lead to changes in patient functioning. The Rehabilitation Treatment Specification System (RTSS) provides guidance to identify the critical aspects of any rehabilitation therapy and supported the development of standardly named ingredients and targets in voice therapy (Rehabilitation Treatment Specification System for Voice Therapy [RTSS-Voice]). This study sought to test the content validity of the RTSS-Voice and determine if the RTSS-Voice can be used to identify commonalities and differences in treatment (criterion validity) across clinicians in everyday clinical practice.

METHOD: Five speech-language pathologists from different institutions …

Understanding The Effects Of Hormone Treatments On The Transgender Singer: A Pedagogical Study And Voice Studio Guide, Erin M. Hannon

Theses and Dissertations--Music

Transitioning from one gender to another can be an arduous and emotionally charged experience, accompanied by many physical and mental transformations. The journey of self-discovery and vocal explorations is both unique and deeply personal. Modifications that emerge in an individual's vocal characteristics have a profound influence on their capacity to communicate and express themselves.

Transgender vocal students and professional singers must navigate the delicate balance between their vocal and gender identities while considering the possible risks of Gender Affirming Hormone Therapy. Though these therapies may significantly alter one's appearance and overall well-being, they are also capable of causing notable declines …

Voices In End-Of-Life Care: Gathering Perspectives Of Speech-Language Pathologists On End-Of-Life Issues In Medical Settings, Kori Bess Benton

Online Theses and Dissertations

Despite healthcare professionals becoming increasingly aware of the needs of the end-of-life care population, little research exists regarding the roles speech-language pathologists play in providing care for that population. This study investigates perspectives of speech-language pathologists on their roles and preparedness for engaging in end-of-life care. Eight participants engaged in semi-structured interviews to share their experiences in end-of-life care. Interviews were conducted and transcribed, then analyzed to establish common themes amongst speech-language pathologists working in this setting. This study found that speech-language pathologists do not feel they received adequate training related to their role in end-of-life care and share unique …

Hereditary spastic parapareses (HSPs) are clinically heterogeneous motor neuron diseases with variable age of onset and severity. Although variants in dozens of genes are implicated in HSPs, much of the genetic basis for pediatric-onset HSP remains unexplained. Here, we re-analyzed clinical exome-sequencing data from siblings with HSP of unknown genetic etiology and identified an inherited nonsense mutation (c.523C>T [p.Arg175Ter]) in the highly conserved RAB1A. The mutation is predicted to produce a truncated protein with an intact RAB GTPase domain but without two C-terminal cysteine residues required for proper subcellular protein localization. Additional RAB1A mutations, including two frameshift mutations and …
