Neural Control Of Swallowing In Infants: White Matter Tracts Associated With Swallow Function, Heather Christine Mcghee

MUSC Theses and Dissertations

This dissertation investigates innovative approaches to improve feeding and swallowing outcomes in infants, particularly those born prematurely or with brain injury. It focuses on understanding the neural networks involved in sucking and swallowing by utilizing diffusion kurtosis imaging (DKI), a more sensitive neuroimaging technique than traditional MRI, and the BaByVFSSImP, a standardized tool for assessing swallow function. Additionally, the research explores the use of transcutaneous auricular vagus nerve stimulation (taVNS) as a neuromodulation technique to enhance oral feeding skills. The study found no adverse effects from taVNS on airway protection or swallowing physiology. Furthermore, there were some possible associations between …

Bridging The Gap Between Clinical Practice And Evidence For Hyolaryngeal Excursion Assessment During A Clinical Swallow Evaluation, Kelsey Murray

Dissertations, 2020-current

This study investigated current practices of subjective hyolaryngeal excursion (sHLE) assessment during a clinical swallow evaluation (CSE) among speech-language pathologists (SLPs) using a survey-based approach. A sample of 77 SLPs in the United States completed an online survey rating their perceived importance and practice of sHLE assessment during a CSE. Additionally, the survey inquired about inferred interpretations from assessing sHLE. Results indicated a strong positive correlation between the rated importance of sHLE assessment and the reported frequency with which it is completed, r_s(46) = .720, p < .001. However, the findings also suggested that some SLPs are not assessing sHLE during a CSE. This offers valuable insight into the prevailing practices of HLE assessment among SLPs, considering the limited evidence for HLE assessment and interpretation. Interpretation and generalizations of the findings is limited due to the small sample size. Findings, however, do support the need for future research investigating the validity of sHLE assessment performed during a CSE, with the aim of providing evidence to guide clinical best practices.

Cortical And Subjective Measures Of Individual Noise Tolerance Predict Hearing Outcomes With Varying Noise Reduction Strength, Subong Kim, Susan Arzac, Natalie Dokic, Jenn Donnelly, Nicole Genser, Kristen Nortwich, Alexis Rooney

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Noise reduction (NR) algorithms are employed in nearly all commercially available hearing aids to attenuate background noise. However, NR processing also involves undesirable speech distortions, leading to variability in hearing outcomes among individuals with different noise tolerance. Leveraging 30 participants with normal hearing engaged in speech-in-noise tasks, the present study examined whether the cortical measure of neural signal-to-noise ratio (SNR)—the amplitude ratio of auditory evoked responses to target speech onset and noise onset—could predict individual variability in NR outcomes with varying strength, thus serving as a reliable indicator of individual noise tolerance. In addition, we also measured subjective ratings of …

The Role Of The Dorsolateral Prefrontal Cortex In Bilingual Language Switching And Non-Linguistic Task-Switching: Evidence From Multi-Voxel Pattern Analysis, Kelly A Vaughn, Benjamin J Tamber-Rosenau, Arturo E Hernandez

Faculty, Staff and Student Publications

Previous research suggests that bilingual language control requires domain-general cognitive control. Recent research suggests that exploration of individual differences is key for understanding the relationship between bilingual language control and cognitive control. The current study used multi-voxel pattern analysis (MVPA) to examine within-subject patterns of fMRI activity in the dorsolateral prefrontal cortex (DLPFC) during bilingual language switching and non-linguistic task-switching. We hypothesized that bilinguals would have identifiable, within-subject patterns of DLPFC activity for both types of switching and that bilinguals and monolinguals would differ in patterns of DLPFC activity for task-switching. We were unable to identify patterns of DLPFC activity …

The Impact Of Hearing Impairment On Patient Care And Autonomy, Savannah Baimbridge, Julie Neil, Gabriel M Aisenberg

Faculty, Staff and Student Publications

Sensory deficits, including hypoacusis, can cause a barrier to communication between healthcare providers and patients, which in turn can lead to misdiagnosis and loss of patient autonomy. Such deficits are frequently overlooked in clinical encounters. We present a 92-year-old Spanish-speaking female who presented twice to the Emergency Department for complications of a diabetic foot infection. Limited evaluation, documentation, and accommodations regarding the patient's hypoacusis led to a misinterpretation of her mental status and a transfer of decision-making to surrogates. A two-toe amputation, mechanical intubation, and intensive care unit stay were followed. It was only after these events that the caregivers …

Working With Bilingual Populations: Clinical Practices Of Speech-Language Pathologists In New Mexico, Wylie L. Skillman

Speech and Hearing Sciences ETDs

New Mexico is uniquely positioned as a state that has more bilingual speakers than the United States on average, meaning that Speech Language Pathologists (SLPs) here are more likely to work with bilingual speakers than elsewhere. Best practices for bilingual evaluation and treatment are taught in graduate education for SLPs but the extent to which they are known and utilized by school-based SLPs differs based on many factors.

As the body of research supporting culturally responsive bilingual assessment and intervention continue to grow, it is unknown how or if clinicians are using this knowledge to assess and treat students who …
