The Role Of The Speech-Language Pathologist With Survivors Of Traumatic Brain Injury From Intimate Partner Violence And Providers’ Knowledge Of This Role, Nicolle Mcadams

Electronic Theses and Dissertations

Intimate partner violence occurs globally at alarming rates. Many experience adverse health impacts such as traumatic brain injury. Healthcare providers do not know the role of the speech-language pathologist, or the rehabilitation needs of survivors.

Aims: This scoping review aims to identify speech-language pathology services for survivors of intimate partner violence with a resulting traumatic brain injury, and knowledge of healthcare providers on the rehabilitation needs of this population. A search was completed in May to October 2023, resulting in a total of 13 articles reviewed.

Main contributions: Speech-language pathologists lack knowledge to provide services to intimate partner violence survivors …

Numerical Investigation Of Subglottal Stenosis Effects On Human Voice Production, Dariush Bodaghi

Electronic Theses and Dissertations

This dissertation aimed to advance knowledge of how subglottal stenosis impacts voice production physiology. An in-house fluid-structure-acoustic interaction approach based on the hydrodynamic/acoustic splitting technique was employed. This technique was rigorously verified for simulating phonation by matching the acoustic behavior to a compressible flow solver for phonation-relevant geometries. Simulations of an idealized 2D vocal tract model demonstrated the effects of supraglottal acoustic resonance on vocal fold kinematics and glottal flow waveform. Results showed that the acoustic coupling between higher harmonics and formats generated pressure oscillations, modifying vocal fold dynamics and glottal flow rate.

A major novelty was the incorporation and …

The Effect Of Telepractice On Vocal Interaction Between Provider, Deaf And Hard-Of-Hearing Pediatric Patients, And Caregivers., Abigail Betts

Electronic Theses and Dissertations

The purpose of this thesis is to examine how telepractice affects a vocal interaction between a speech-language pathologist (SLP), deaf and hard-of-hearing children who received cochlear implants (n = 7), and caregivers as they engage in speech-language interventions conducted in-person and via telepractice (tele). Frequency of vocalizations, vocal turns, pause duration, fundamental frequency (F0) mean and range, utterance duration, syllable rate per utterance duration, and mean length of utterance (MLU) were examined. The SLP vocalized more during in-person than tele-sessions, opposite result for the mother. There were more SLP-child turns during in-person sessions than tele-sessions; opposite result for mother-child turns. …

School-Based Speech-Language Pathologist's Perceptions Of Sensory Food Aversions In Children, Ellen Monroe

Electronic Theses and Dissertations

Sensory Food Aversions occur frequently in children who are likely to appear on Speech-Language Pathologist’s (SLP’s) caseloads. The lack of research regarding intervention for Sensory Food Aversions in schools and the assertion of a gap in school-based services for children with feeding disorders was a significant indicator for the need of the study. A quantitative, descriptive, exploratory research design was selected using a self-developed questionnaire in order to exploreschool-based SLP’s perceptions of their knowledge and skills related to Sensory Food Aversions, as well as determine resources available for working with this population. Findings from the study suggest a need for …

Factors Of Dysphagia In The Overdose Population Post Extubation., Renee Brown

Electronic Theses and Dissertations

Post-extubation dysphagia (PED) has been studied in depth in a variety of populations including elective heart surgeries, trauma, critical illness, traumatic brain injury, and those requiring mechanical ventilation, but has not been researched in the overdose population (OD). This study aims to research factors of PED in the OD population. A retrospective study was conducted and found 24 participants who fit the inclusionary requirements. Correlation statistics were run between age and duration of intubation, age or duration of intubation and gender, and between intubation duration, age, and scores on Penetration-Aspiration Scale (P/A) (thin by cup and thin by straw). The …

Investigating Predictive Relationships Between Speech-Language Pathology Graduate Students' Sense Of Classroom Community, Perceived Learning, And Perceived Anxiety., Emily B. Schantz

Electronic Theses and Dissertations

Mental health is an all-encompassing term that focuses on a person’s ability to achieve work-life balance inclusive of positive mental health and mental ill-health. Current trends suggest an overall increase in mental ill-health for undergraduate and graduate students. McMillan and Chavis’ sense of community theory provided the theoretical framework for this study. This study aimed to examine whether speech-language pathology graduate students’ sense of classroom community and perceived learning predict anxiety levels while controlling for demographic variables. Three-hundred-sixteen master’s level speech-language pathology students completed an online survey containing the Generalized Anxiety Disorder Questionnaire, Perceived Learning Scale, and Classroom Community Scale. …

Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …

A Model For Electrical Communication Between Cochlear Implants And The Brain, Douglas A. Miller

Electronic Theses and Dissertations

In the last thirty years, cochlear implants have become an invaluable instrument in the treatment of severe-to-profound hearing impairment. An important aspect of research in the continued development of cochlear implants is the in vivo assessment of signal processing algorithms intended to improve perception of speech and other auditory signals. In trying to determine how closely cochlear implant recipients process sound relative to the processing done by a normal auditory system, various assessment techniques have been applied. The most common technique has been measurement of auditory evoked potentials (AEPs), which involves the recording of neural responses to auditory stimulation. Depending …
