Effect Of Biofeedback And Exercise Type On Neural Swallowing Control, Rachel J. Rinehart
Effect Of Biofeedback And Exercise Type On Neural Swallowing Control, Rachel J. Rinehart
Senior Honors Projects, 2010-2019
The clinical efficacy of swallowing exercises is well established in swallowing literature, and biofeedback has been shown to augment cortical hemodynamic response (HDR) during normal swallowing. This study compared HDR during swallowing exercises with and without biofeedback to HDR during normal swallows with and without biofeedback. Healthy adult participants (n=6, mean age=50.83 male=2) were recruited and trained on the following conditions: normal swallowing, swallowing exercise in which a specific physiological target was given (skilled), and swallowing exercises in which no specific physiological target had to be achieved (non-skilled). Biofeedback consisted of submental surface electromyography (sEMG) signals displayed visually. HDR were …
Effects Of Training And Lung Volume Levels On Voice Onset Control And Cortical Activation In Singers, Nicholas A. Barone
Effects Of Training And Lung Volume Levels On Voice Onset Control And Cortical Activation In Singers, Nicholas A. Barone
Dissertations, 2014-2019
Singers need to counteract respiratory elastic recoil at high and low lung volume levels (LVLs) to maintain consistent airflow and pressure while singing. Professionally trained singers modify their vocal and respiratory systems creating a physiologically stable and perceptually pleasing voice quality at varying LVLs. In manuscript 1, we compared non-singers and singers on the initiation of a voiceless plosive followed by a vowel at low (30% vital capacity, VC), intermediate (50%VC), and high (80%VC) LVLs. In manuscript 2, we examined how vocal students (singers in manuscript 1) learn to control their voice onset at varying LVLs before and after a …
A Comparison Of Vibrotactile And Air Puff Stimulation For Inducing Swallowing, Kathryn Diane White
A Comparison Of Vibrotactile And Air Puff Stimulation For Inducing Swallowing, Kathryn Diane White
Dissertations, 2014-2019
The purpose of this study was to evaluate the effectiveness of two types of non-invasive, sensory stimulation on increasing the rate of swallowing and for inducing cortical activity associated with swallowing. The types of stimulation investigated were vibrotactile stimulation to the external throat area surrounding the laryngeal tissues and oral air puff stimulation to the anterior faucial pillars. A functional near infrared spectroscopy (fNIRS) system measured relative changes in the concentration of oxygenated hemoglobin (HbO) in cortical sensorimotor regions as an indirect measure of brain activity. The experiment included 16 healthy adult participants between the ages of 28 and 60 …
Investigating Motor Training In People Who Stutter Using Fnirs, Kristen Michelle Johnson
Investigating Motor Training In People Who Stutter Using Fnirs, Kristen Michelle Johnson
Masters Theses, 2010-2019
This pilot study investigated motor learning and neuroplasticity in persons who do and do not stutter before and after participation in a phonation onset training protocol. Outcomes included phonation onset time and percent change in oxygenation level of hemoglobin using fNIRS in prescribed brain areas as a result of training. The authors hypothesized that people who stutter (PWS) would 1) exhibit a breakdown in auditory perception to motor production interactions, 2) demonstrate a difference in the way in which they perceive and learn motor information compared to someone who does not stutter (nPWS), and 3) exhibit reduced brain activity correlations …
