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 …
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. …

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

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 …
