Neural Control Of Tongue Movements Across Effort Levels, Megan Rovang, Angela M. Dietsch 2016 University of Nebraska-Lincoln

Neural Control Of Tongue Movements Across Effort Levels, Megan Rovang, Angela M. Dietsch

UCARE Research Products

Background

A hallmark of Parkinson’s disease (PD) is a mismatch between the perceived effort and actual forces exerted during functional activities such as speech. Current evidence supports therapy to help reset this perception of effort, but the neurological underpinnings of such treatments are unclear. This study examined brain activity during tongue movements performed at varying levels of effort to determine (1) which brain areas are involved in each task, and (2) which areas, if any, scale in activation according to effort level. These results, considered with the neurological changes associated with PD, can be used to develop and refine ...


Predictors Of Language Outcome For Children In The Ontario Infant Hearing Program, Olivia M. Daub 2016 The University of Western Ontario

Predictors Of Language Outcome For Children In The Ontario Infant Hearing Program, Olivia M. Daub

Electronic Thesis and Dissertation Repository

The Ontario Infant Hearing Program (OIHP) provides early interventions (i.e., hearing aids) to children who are hard of hearing (CHH) because research consistently demonstrates their benefit to language outcomes. The impact of pre-fitting language abilities on these outcomes are not well understood.

This retrospective cohort analysis examined the performance of OIHP children on the Preschool Language Scale-4 at the time of (n=47), and after (n=19), initial hearing aid intervention. Regression analyses revealed that, before amplification, hearing loss severity predicted language abilities. However, after amplification, severity of hearing loss did not uniquely predict language achievement, but rather was ...


A Qualitative Assessment Of What Comprises An Effective And Positive Supervisor-Student Clinician Relationship In Speech-Language Pathology, Jessica Atick Fencel 2016 Florida International University

A Qualitative Assessment Of What Comprises An Effective And Positive Supervisor-Student Clinician Relationship In Speech-Language Pathology, Jessica Atick Fencel

FIU Electronic Theses and Dissertations

The purpose of this study was to gain a better understanding of the factors that constitute a positive and negative supervisor-supervisee relationship as perceived by speech-language pathology graduate students. Clinical practicum experiences were analyzed using qualitative methods via recorded in-depth participant interviews. After the data were collected and transcribed, the narratives were analyzed to draw useful inferences and discover underlying themes using a phenomenological methodology approach. Two overlaying themes, ASHA’s Task 1 of Supervision and Anderson’s Continuum Model of Supervision, were identified from the participants’ interviews and were used to categorize the data. Results indicate the most likely ...


Assessing Excessive Noise Exposure Of Music-Oriented Nightclub Employees, Aiyanna Fitzgerald 2016 University of South Florida

Assessing Excessive Noise Exposure Of Music-Oriented Nightclub Employees, Aiyanna Fitzgerald

Graduate Theses and Dissertations

Much research has gone into noise-induced hearing loss (NIHL) and the effects of high intensity noise levels on the hearing mechanism of individuals. A study by the National Institutes of Health has established that high intensity sounds can cause hearing damage of either a temporary, or worse, a permanent nature; regardless of the age of the person. While sound levels below 75 decibels are considered comparatively harmless and have been found not to cause any kind of permanent hearing loss; sound levels greater than 85 decibels and regular exposure of approximately 8 hours per day, on an average, has been ...


Hearing Aid Use And Cognitive Function: A Systematic Review, Hershel Korngut 2016 Graduate Center, City University of New York

Hearing Aid Use And Cognitive Function: A Systematic Review, Hershel Korngut

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

This systematic review analyzed the research relating the use of hearing aids to cognitive function. Hearing aid use was examined to see if wearing hearing aids improves cognitive function, if the length of time hearing aids are worn impacts cognitive ability, if the type of hearing aid used has any impact on cognitive function, and if hearing aid use slows down cognitive decline. Ten studies met the criteria for this review. An analysis of the research revealed some evidence to support wearing hearing aids improves cognitive function, however, there is substantial evidence that shows no impact between wearing hearing aids ...


Annexin A5 Is The Most Abundant Membrane-Associated Protein In Stereocilia But Is Dispensable For Hair-Bundle Development And Function, Jocelyn F.

Annexin A5 Is The Most Abundant Membrane-Associated Protein In Stereocilia But Is Dispensable For Hair-Bundle Development And Function, Jocelyn F. Krey, Meghan Drummond, Sarah Foster, Edward Porsov, Sarath Vijayakumar, Dongseok Choi, Karen Friderici, Sherri M. Jones, Alfred L. Nuttall, Peter G. Barr-Gillespie

Special Education and Communication Disorders Faculty Publications

The phospholipid- and Ca2+-binding protein annexin A5 (ANXA5) is the most abundant membrane-associated protein of ~P23 mouse vestibular hair bundles, the inner ear’s sensory organelle. Using quantitative mass spectrometry, we estimated that ANXA5 accounts for ~15,000 copies per stereocilium, or ~2% of the total protein there. Although seven other annexin genes are expressed in mouse utricles, mass spectrometry showed that none were present at levels near ANXA5 in bundles and none were upregulated in stereocilia of Anxa5−/− mice. Annexins have been proposed to mediate Ca2+-dependent repair of membrane lesions, which could be part of ...


Coding Strategies For Cochlear Implants Under Adverse Environments, Qudsia Tahmina 2016 University of Wisconsin-Milwaukee

Coding Strategies For Cochlear Implants Under Adverse Environments, Qudsia Tahmina

Theses and Dissertations

Cochlear implants are electronic prosthetic devices that restores partial hearing in patients with severe to profound hearing loss. Although most coding strategies have significantly improved the perception of speech in quite listening conditions, there remains limitations on speech perception under adverse environments such as in background noise, reverberation and band-limited channels, and we propose strategies that improve the intelligibility of speech transmitted over the telephone networks, reverberated speech and speech in the presence of background noise. For telephone processed speech, we propose to examine the effects of adding low-frequency and high- frequency information to the band-limited telephone speech. Four listening ...


Interprofessional Patient Simulation Training Compared To Online Training For Learning To Use In-Line Speaking Valves, Kristi A. Moore 2016 East Tennessee State University

Interprofessional Patient Simulation Training Compared To Online Training For Learning To Use In-Line Speaking Valves, Kristi A. Moore

Electronic Theses and Dissertations

Restoring speech in persons who are tracheostomy and ventilator dependent, through the use of a Passy-Muir Speaking Valve (PMSV), requires specific training. Methods of training interprofessional team members to assess in-line PMSVs are unclear. This study used a pretest/ post-test design to compare effects of online training and online training plus simulation training on knowledge acquisition, skills performance, and comfort levels when working with persons who are tracheostomy and ventilator dependent. Twenty-six students studying either respiratory therapy (N=13) or speech-language pathology (N=13) were assigned to the control group or experimental group. Results revealed that online training proved beneficial ...


Comparison Of In Vivo Simulation Training Compared To Video Simulation Training For Identifying Clinical Markers Of Distress When Feeding Preterm Infants, Emily M. Wagner 2016 East Tennessee State Universtiy

Comparison Of In Vivo Simulation Training Compared To Video Simulation Training For Identifying Clinical Markers Of Distress When Feeding Preterm Infants, Emily M. Wagner

Electronic Theses and Dissertations

Preterm infants have multiple health complications due to their underdeveloped neurological systems. Bottle-feeding difficulties are one complication that leads to pulmonary illness secondary to aspiration. Preterm infants exhibit clinical markers when experiencing distress during bottle-feeding. Training caregivers to identify clinical markers reduces the risk for aspiration. Simulation training provides a safe learning environment without harming patients. Twenty-two speech-language pathology and pre-requisite students divided into two simulation groups, video-simulation (N=12) and in-vivo simulation (N=10), were trained to document clinical markers of distress exhibited by preterm infants and make clinical judgments about bottle-feeding. Students rated their levels of anxiety during ...


The Effect That Design Of The Nucleus Intracochlear Electrode Array And Age Of Onset Of Hearing Loss Have On Electrically Evoked Compound Action Potential Growth And Spread Of Excitation Functions, Li-Kuei Chiou 2016 University of Iowa

The Effect That Design Of The Nucleus Intracochlear Electrode Array And Age Of Onset Of Hearing Loss Have On Electrically Evoked Compound Action Potential Growth And Spread Of Excitation Functions, Li-Kuei Chiou

Theses and Dissertations

The purpose of this study was to investigate how design changes in Cochlear Nucleus cochlear implants (CIs) (CI24M, CI24R, CI24RE and CI422) affected electrode impedance and ECAP measures, and to determine if these design changes affected post-lingually deafened adults and children with congenital hearing loss in a similar way.

Results of this study showed that electrode impedance was inversely related to the area of the electrode contacts in the array: lowest for the full-banded CI24M CI and highest for adults who used the CI422 device which has the smallest electrode contacts of all four devices. The noise floor of the ...


The Effects Of Articulation Errors On Perceived Nasality In Speakers With Repaired Cleft Lip And/Or Palate, Kristin Louise Dattilo 2016 University of Iowa

The Effects Of Articulation Errors On Perceived Nasality In Speakers With Repaired Cleft Lip And/Or Palate, Kristin Louise Dattilo

Theses and Dissertations

The purpose of this study was to further investigate the effects of articulation errors on perceptual ratings of nasality in speakers with repaired cleft palates, specifically looking at the effect of varying magnitudes of articulation errors and education on perception of nasality. A group of expert listeners, speech-language pathologists with significant clinical experience in the area of cleft palate and resonance disorders, first rated the articulatory proficiency and nasality of a number of utterances produced by children with repaired cleft palates, on separate 6-point scales. Their ratings were then used to categorize stimuli into a three-by-three matrix (mild, moderate, severe ...


Examiner And Child Contributions To Therapy, Rebecca Lyrenmann 2016 University of Iowa

Examiner And Child Contributions To Therapy, Rebecca Lyrenmann

Theses and Dissertations

The purpose of this research was to analyze child and clinician factors affecting language therapy outcomes and to analyze the potential bi-directional relationship between child and clinician factors. Transcripts of intervention sessions with one child and one trained examiner were coded for factors relating to children's language ability, examiners' strategies for reaching session targets, and differences in examiners' interactional styles. It was found that differences in children's language ability and examiners' interactional styles did not have a strong relationship with therapy outcomes. Differences were observed in the overall frequency of examiners' strategy use across children; however, examiners were ...


Effects Of Fitzmaurice Voicework® On The Voice Of Graduate Student Actors, Brock Irvin Meadath 2016 University of Iowa

Effects Of Fitzmaurice Voicework® On The Voice Of Graduate Student Actors, Brock Irvin Meadath

Theses and Dissertations

The vocal demands placed on actors are higher than those of the typical speaker. Actors' livelihood is predicated on their ability to consistently perform at peak levels, many times in conditions that are not optimal for vocal efficiency (e.g. theaters with poor acoustics). Further, many actors perform after spending the day at a second job to ensure they have a sufficient income to support themselves. Despite challenges, the hallmark of the strong actor is to strive for peak performance. To do so, many actors implement some form of theatre voice training.

One popular method is Fitzmaurice Voicework®. Fitzmaurice Voicework ...


Parent And Child Perceptions Of Disordered Speech Associated With Cleft Lip And/Or Palate, Kristina Lynn Warndahl 2016 University of Iowa

Parent And Child Perceptions Of Disordered Speech Associated With Cleft Lip And/Or Palate, Kristina Lynn Warndahl

Theses and Dissertations

Background & Purpose

Approximately 50β of children born with cleft lip and/or palate (CL/P) will need speech and language intervention (Lockhart, 2003). Speech difficulties are related to poorer academic performance, higher risk of retention in younger grades, and greater risk of being bullied or having a low self-esteem (Byrd, 1994; Lockhart, 2003). Since parents are the primary decision makers when it comes to treatment for their child, how closely do parents' perceptions of speech, appearance, and emotional consequences match the perception of their child? This study assessed differences in perceptions between parents and children with CL/P regarding speech, the emotional impact of having a cleft, and quality of life.

Methods & Description

Twenty parent-child dyads were recruited at a University based cleft palate clinic. The children were between 7 and 17 years of age, with a diagnosis of cleft palate, cleft lip and alveolus, submucous cleft only, or cleft ...


The Effect Music Has In Speech Therapy, Emily K. Nester 2016 The University of Southern Mississippi

The Effect Music Has In Speech Therapy, Emily K. Nester

Honors Theses

The purpose of this exploratory study was to determine the use of music in speech therapy. A survey was sent via email to Mississippi Speech-Language-Hearing Association (MSHA) certified speech-language pathologists to acquire knowledge on the use of music in their therapy sessions. The author used the source, SurveyMonkey, to collect and analyze the data. The data was used to determine the prevalence of music in speech therapy. In addition, when music was used, the data portrayed how music was incorporated into therapy and the particular gender, genre, and/or disorder preferred.


The Effect Of Easy Onset Time Treatment On Voice Onset Time In Stuttering, Candace M. Franklin 2016 The University of Southern Mississippi

The Effect Of Easy Onset Time Treatment On Voice Onset Time In Stuttering, Candace M. Franklin

Honors Theses

For over 70 million people who stutter, it is a disorder that can affect a person’s social, emotional, and professional life on a daily basis (Gordon, 2002). Stuttering is defined as a fluency disorder that includes the repetition of words, pauses in speech, or sound prolongation (Hedge, 2001). Although there are many different theories as to what causes stuttering, the etiology of stuttering remains undetermined. As a result, much research has been done on various treatment approaches to try and ease the effects of stuttering. One particular approach is the Easy Onset Time approach. This approach encourages the client ...


List Equivalency Of The Azbio Sentence Test, Lauren C. Bush 2016 The University of Southern Mississippi

List Equivalency Of The Azbio Sentence Test, Lauren C. Bush

Honors Theses

The AzBio Sentence Test was developed as a measure of speech perception abilities and intended to be more reliable and closer to real life conditions than the previous speech perception measures commonly used. The purpose of speech perception measures is to partially determine cochlear implant candidacy as well as pre- and post-outcomes of cochlear implantation. The AzBio Sentence test is composed of 15 lists of 20 sentences each. There is limited research conducted on the equivalency of each of these lists. Of the previous limited reasearch conducted, one study found that only 10 of the 15 lists were equivalent. The ...

A Case Study Of Cochlear Implants And Complications, Carly E. Amurao 2016 University of Rhode Island

A Case Study Of Cochlear Implants And Complications, Carly E. Amurao

Senior Honors Projects

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear, allowing the individual access to sound. In recent years, there has been tremendous progress in developing technology in the area of cochlear implants to aid those with severe/profound hearing loss. Specifically, there has been a movement towards bilateral implantation. Each cochlear implant candidate has a unique hearing loss, and must reach required bench marks in order to be considered a viable candidate for a cochlear implant. This process includes: meeting the required level of hearing loss, a required trial with hearing aids ...
