Potential Benefits And Withdrawal Effects Of Cranial Nerve Non-Invasive Neuromodulation On Functional Mobility For Individuals With Traumatic Brain Injury, Kati P. Liegl

Theses and Dissertations

Objective: Document and describe benefits and withdrawal effects of the Cranial Nerve Non-Invasive Neuromodulation (CN-NINM) intervention.

Background: Neuromodulation techniques can be used for the treatment of many diagnoses and conditions. Many current neuromodulation techniques have or can have negative consequences such as high cost, risk of surgical complications or infections, effects not lasting without the drug or stimulation presence, and need for medical experts' direct oversight. A new rehabilitation intervention called CN-NINM may eliminate these negative factors, making it a promising tool for clinicians and participants. CN-NINM combines targeted training activities with mild, portable, electrical stimulation of the tongue to …

Feasibility And Preliminary Outcomes From A Pilot Study Of The Smile Curriculum For Mother-Infant Co-Occupational Engagement And Maternal Self-Efficacy, Emily Whitlock

Theses and Dissertations

OBJECTIVE: To report on the feasibility and preliminary outcomes from a pilot study of the SMILE curriculum, a new educational program designed to enhance the mother-infant relationship by focusing on improvement of co-occupational engagement within daily routines.

METHOD: Six mothers, each with an infant diagnosed with special medical needs who received services in a local birth-to-three program, participated in an exploratory design study. Each mother was assigned to a SMILE curriculum intervention group or a waiting-list control group. Mothers were evaluated pre- and post-intervention using the Perceived Maternal Parenting Self-Efficacy (PMP-SE) Scale for measurement of maternal self-efficacy and the Center …

Perceptual Correlates Of Acoustic Measures Of Vocal Variability, Bree Ann Cumbers

Theses and Dissertations

This study investigated relationships between acoustic measures of vocal variability (pitch sigma, SFF range) and perceptual ratings of vocal variability during a reading task. Fifteen male (19-30 years of age) and nineteen female speakers (20-30 years of age) who were recorded reading the Grandfather Passage provided the stimuli for the listening task. From these samples, 30 were selected as representing a continuum of degrees of vocal variability. Male (N = 15) and female (N = 15) samples were presented to listeners separately. Thirty graduate students in Communication Sciences and Disorders who had a course background in voice supplied the perceptual …

Measuring Outcomes Of Rehabilitation Among Persons With Upper Extremity Traumatic Injuries, Jamie Carl Grede

Theses and Dissertations

Grip strength is frequently measured to determine outcomes of rehabilitation among people with upper extremity traumatic injuries (UETIs). UETIs also affect rate of force-production during an isometric grip. However, we do not have a reliable and valid measure for detecting these force changes. The purpose of this study was to determine the validity and responsiveness, i.e. ability to detect change, of the Force-Time Curve (F-T Curve) to determine rate of force production. Twenty people with UETIs undergoing rehabilitation were recruited to participate in this study. Using an electronic Jamar dynamometer, each participant performed three maximal isometric grips, each lasting 10 …

Acoustic Characteristics Of Tense And Lax Vowels Across Sentence Position In Clear Speech, Lindsay Kayne Roesler

Theses and Dissertations

The purpose of this study was to examine the acoustic characteristics of tense and lax vowels across sentence positions in clear speech. Recordings were made of 12 participants reading monosyllabic target words at varying positions within semantically meaningful sentences. Acoustic analysis was completed to determine the effects of Style (clear vs. conversational), Tenseness (tense vs. lax), and Position (sentence-medial vs. sentence-final) on vowel duration, vowel space area, vowel space dispersion, and vowel peripheralization. The results showed speakers had longer durations and expanded vowel spaces in clear speech for both tense and lax vowels. Importantly, the amount of increase was similar …

The Effects Of Expiratory Muscle Strength Training On Swallowing And Voice Measures In Healthy Older Adults, Adam Follmer

Theses and Dissertations

This study investigated the effects of a four week expiratory muscle strength training (EMST) exercise program on healthy older adults (65-79 years). The investigators were interested in possible changes to the swallowing and voice production systems, both of which are in the scope of practice for a speech language pathologist. Specific voice variables included maximum phonation time, conversational intensity level, and upper and lower limits of available intensity range. Swallowing variables were related to tongue function and included maximum isometric pressure and mean swallowing pressure. Finally, maximum expiratory pressure was measured as a comparative value to other EMST studies. A …

Cepstral- And Spectral-Based Acoustic Measures Of Normal Voices, Rachel Garrett

Theses and Dissertations

A review of recent literature suggested that cepstral- and spectral-based acoustic measures showed good potential as objective measures of dysphonia for clinical application. However, the small numbers of normal subjects in previous research and wide age ranges prevent a good estimation of the performance of normal speakers of various ages on these measures. Therefore, the purpose of this study was to provide normative data for Long-Term Average spectral- and cepstral-based measures for both men and women in two different age groups to aid clinicians with assessing and treating voice disorders. Sixty participants consisting of fifteen males and fifteen females, ages …

Optimizing Hand Crank Configuration For Therapeutic Use Of Amtrykes® For Children With Upper Extremity Motor Deficits, Jennifer Hardy

Theses and Dissertations

Objective

The purpose of this research study was to create a model to assist therapists, that determines the optimal positioning of the hand cranks when fitting a child for an AmTryke® with a disability that limits upper body strength, such as a brachial plexus injury.

Method

A fitting model was developed by testing the amount of force required to start moving the hand cranks on the AmTryke® when various amounts of weight were applied to the seat of the device. The data collected inserted into a table. A questionnaire developed and emailed to a convenient sample of pediatric physical and …

Kinematic And Kinetic Comparisons Of Arm And Hand Reaching Movements With Mild And Moderate Gravity-Supported, Computer-Enhanced Armeo®Spring: A Case Study, Qussai M. Obiedat

Theses and Dissertations

Background: Stroke has been recognized as a leading cause of serious long-term disability in the United States (U.S.) with 795,000 people experience a new or recurrent stroke each year (Roger et al., 2011). The most apparent defect after stroke is motor impairments (Masiero, Armani, & Rosati, 2011). Statistically, half of stroke survivors suffer from upper extremity hemiparesis and approximately one quarter become dependent in activities of daily living (Sanchez et al., 2006). There is strong evidence that intensity and task specificity are the main drivers in an effective treatment program after stroke. In addition, this training should be repetitive, functional, …

Examining The Lived Experience Of Student Veterans Using Photovoice Methodology, Nikhil Tomar

Theses and Dissertations

The primary objective of this study was to understand the lived experience of student veterans using photovoice methodology. After returning from service veterans struggle most with school (Plach & Haertlein Sells, 2013). Student veterans experience difficulty in time management, and transitioning to student life (Radford, 2009). They spend more time working at jobs and caring for dependents than non-veteran students, but spend equivalent time studying. They perceive less engagement with faculty and campus support than their peers (NSSE, 2010). For many veterans, education is a primary occupation but there is dearth of data about their lived experience and factors that …
