Chew On It: A Pilot Study Of A Multimodal Assessment Of Mastication Protocol, Michelle Catão

Electronic Theses and Dissertations

Despite its subconscious nature, deglutition is an elaborate and multifaceted process, contingent on the activation of specific neural pathways and muscles. The inherent complexity gives rise to a wide array of potential complications and difficulties, known as dysphagia. Screening and assessment for dysphagia aid in determining the presence and etiology of swallowing difficulties, providing information that is critical for maintaining and improving the health status of vulnerable populations from the standpoint of nutrition, hydration, and socialization (Dziewas et al., 2017). Previous studies surrounding dysphagia assessment have prioritized formulating clinical protocols to evaluate the nonvolitional stage, often failing to address the …

An Implementation Study Of Phonological Awareness Assessment Tasks For Literacy Development In D/Deaf And Hard Of Hearing Students, Sara Tuddenham

Long-Term Changes In Bolus Parameters During Swallowing Post-Chemoradiation Treatment., Brittany Rebecca Smiley

Electronic Theses and Dissertations

Current treatment for oropharyngeal cancer involves chemoradiation, which can have profound effects on swallowing function. Submental muscle activity is critical for airway protection and bolus transit but is highly susceptible to radiation-related swallowing impairments. This study examined whether chemoradiation targeting the submental muscles leads to measurable changes in esophageal distension during swallowing in a rodent model. We hypothesized that rats receiving chemoradiation would exhibit aberrant esophageal distension compared to chemotherapy-only controls. Twenty male rats underwent four cycles of cisplatin concurrently with either radiation or sham radiation. High-speed videofluoroscopy swallow studies were conducted pre- and post-treatment with thin liquids to analyze …

There were more SLP-child turns during in-person sessions than tele-sessions; opposite result for mother-child turns. …

Qualitative Study Of Collaboration Between Independent Reading Specialists And Elementary Classroom Teachers, Lindsay Lee Hawbaker

Electronic Theses and Dissertations

Abstract

The failure of educators to meet the needs of elementary students who require separated, differentiated, and intensive reading interventions (Tier 3) has been attributed to the scarcity of administrative resources and a lack of effective collaboration between reading specialists and classroom teachers. Experts opine that common barriers to effective collegial collaboration between institutional reading specialists, who are employed by the school, and classroom teachers include: an unsupportive school culture, the classroom teachers’ fear of losing pedagogical autonomy, the absence of mutual trust and interdependence between the reading specialists and their students’ classroom teachers, and the inability of reading specialists …

Aphasia Friendly Medication Instructions: Effects On Comprehension In Persons With And Without Aphasia, Anna Saylor

Inspiratory Muscle Recruitment During Swallow And A Comparison Across Airway Behaviors., Allison V. English

Electronic Theses and Dissertations

During swallow, a negative esophageal pressure is present that, along positive pressure from the tongue, which works to move the bolus through the pharynx into the esophagus. This negative esophageal pressure is thought to be produced via recruitment of chest wall inspiratory muscles (diaphragm and parasternal). This current study aimed to examine respiratory muscle recruitment across behaviors which have known inspiratory muscle activity (eupnea, augmented breath and cough) and compare to swallow. It was hypothesized that there would be no significant difference in amplitude and muscle recruitment over 75 ms between swallow and eupnea, but cough and augmented breath would …

Alterations In Rhythmic Licking Behaviors Following Fibrosis In The Rat Mylohyoid Muscle., Brittany Fletcher

Electronic Theses and Dissertations

Muscle injury is a common side effect of radiation treatment for head and neck cancer. To increase understanding of muscle injury related dysfunction, we investigated the effects of oral swallowing function after cryoinjury to mylohyoid muscle in rats. The hypothesis is that injury to the mylohyoid delays the temporal licking pattern, resulting in aberrant drinking behaviors. Six rats received bilateral mylohyoid injuries by applying a 3mm cryoprobe. Licking behavior was measured by electrophysiological recordings of rhythmic tongue movements in a ten-minute drinking session taken pre-and post-injury (one-and two-weeks). Lick frequency and total licks per cluster decreased significantly one-and two-weeks post-injury …

The Effect Of The Movie Time Social Learning Method On The Emotional Inferencing Skills In An Adult With Autism Spectrum Disorder, Jenna Reade

Electronic Theses and Dissertations

Individuals with autism spectrum disorder (ASD) have difficulty finding employment and maintaining social relationships. Professional and personal interactions require individuals to make inferences, or read between the lines. Inferencing is a challenge for individuals with ASD because it requires complex information processing. More specifically, it involves the integration of cognitive and linguistic information. There is a lack of research using complex stimuli to treat inferencing. An A-B-A-B design with one adult with ASD was used to examine the effectiveness of a movie-based method, Movie Time Social Learning(Vagin, 2012), on improving the emotional inferencing skills of one young adult with …

A New Surgical Approach For O-C2 Fusion, Solving The Problem Of Dysphagia., M. Kathryn Mcclure

Electronic Theses and Dissertations

The fusion of the second cervical vertebrae to the occipital bone (O-C2 fusion) for head stabilization can result in postoperative dysphagia and dyspnea, negatively impacting the patient’s quality of life. Currently, the O-C2 angle is used for head placement, which may not place the head neutrally. We hypothesize that aligning the external auditory meatus with midline of the C2 will reduce oropharyngeal stenosis, reducing dysphagia. One male patient with poor swallow quality of life who required a revision of a previous O-C2 surgery was evaluated via videofluoroscopy and completed the standard swallow quality of life questionnaire (SWAL-QOL) before and after …

Swallow And Breathing Coordination Following Suprahyoid Muscle Injury., Bradley Kimbel

Electronic Theses and Dissertations

Swallowing motility disorders (dysphagia) are a major complication following radiation treatment for head and neck cancer, affecting ~50% of those treated. One reason for this is that radiation causes muscle damage, provoking sensorimotor pathologies. Previous work has suggested that injury may cause discoordination between breathing and swallowing behaviors. We sought to determine if muscle injury provokes changes in this behavior. We hypothesized that acute suprahyoid muscle damage would alter cross-behavior excitability, causing destabilization of the respiratory-swallow pattern. Swallowing was evoked in anesthetized spontaneously breathing cats via injection of a 3cc bolus of water into the oropharyngeal cavity. A suprahyoid injury …

Autism Spectrum Disorder : Investigating Predictive Diagnostic Relationships In Children Three Years-Of-Age And Younger., Kaitlin Juergensen

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder whose symptoms may involve deficits across three domains: communication, socialization, and atypical behaviors or interests. With a high prevalence across populations and a tendency to impact males more so than females, early and accurate diagnosis appears critical. The most current literature on ASD provides a myriad of difficulties associated with diagnosis under the age of three years. The purpose of this study was to determine if a predictive relationship exists between a child’s individual developmental domain standard deviation (SD) subscale scores (motor, language, cognitive, social-emotional, and adaptive skills) on the Bayley …
