Variability And Stability Of 13 To 19 Month Olds Infants' Gait Affect By Wet And Dry Diaper And Underwear, Sally Marie Futch

Electronic Theses and Dissertations

Research has been conducted on the effect of diaper perturbation versus unclothed on gait, but there is little research on different diaper perturbations on gait. PURPOSE: The purpose of this study was to examine how physical perturbations (dry and wet diaper and underwear) affected 13 to 19 month old infant’s gait. METHODS: Sixty infants (13-19 month old) were recruited for the study. Five trials for 3 conditions (dry and wet diaper and underwear) were conducted on a GaitRite walkway. Step length (m/step), cadence (steps/s), support base (m) and stance time (sec) were analyzed. A mixed model with repeated measures along …

Goal Orientation, Motivational Climate, And Exercise As Predictors Of Eating Disorder Risk Factors Among College Students, Carly Wahl

Electronic Theses and Dissertations

College is a transition period in a young adult’s life in which eating disorder symptomology is especially prevalent. Additionally, motivation-based factors such as goal orientation and motivational climate can influence these eating disorder-like behaviors, especially in a physical activity setting. The present study aimed to examine how goal orientation, motivational climate, and exercise could be used to predict a college students’ eating disorder symptomology. Participants included 276 college-aged males and females from a university in the southeastern United States. These participants had experience using the university recreation activity center and were recruited from a required healthful living course. Each participant …

Treatment Choice Among Combat Veterans, Zachary Clayborne Dietrich

Electronic Theses and Dissertations

A plethora of research has investigated PTSD treatment outcomes among Veterans of foreign wars. However, research has suggested mixed treatment efficacy. Although investigations into factors that may help predict treatment outcomes are emerging, to date no study has evaluated treatment choice among Veteran populations. Previous treatment choice studies have yielded qualitative and quantitative information that can be useful in clinical decision-making. This study looks to build upon the treatment choice literature with combat Veterans to evaluate for underlining characteristics of cohorts that will help build upon existing knowledge. It has been suggested that treatment benefits Vietnam Era Veterans more than …

Validity And Reliability Of The Balance Tracking System™ During Static Stance, Cody L. Grotewold

Electronic Theses and Dissertations

Introduction: The Balance Tracking System™ (BTrackS™) is a balance board designed to quickly analyze postural control through center of pressure (COP) analysis.

Purpose: Examine concurrent validity and test-retest reliability of the BTrackS™ during static stance.

Methods: A convenience sample of 51 healthy collegiate students between 18 - 25 years old (21.8 ± 3.1 years) completed four, 20 second (s) trials of feet together static stance during both eyes open and closed trials. Data was simultaneously collected on the BTrackS™ and a laboratory force plate to establish concurrent validity. A second testing session was administered 48 - 72 …

Reliability And Validity Of The Gwalk For Use In Postural Control, Megan Mormile

Electronic Theses and Dissertations

Introduction: Clinical examinations are highly subjective when compared to the more sensitive and robust measures observed with force platform assessment. Currently, few methods exist to quantify objective postural control deficits in an easier and more accessible way for clinicians. Purpose: The purpose of this study was to examine the reliability and validity of a wireless inertial sensing device, the BTS GWalk, during postural control assessment. Methods: Fifty-six participants (27 male, 22 ± 1.9 years, 29 female, 21 ± 0.9 years) performed three trials each of quiet standing with eyes open (EO) and eyes closed (EC) on a force …

The Effect Of Repetitive Head Impacts On Postural Control Over The Course Of A Single Season, Katelyn E. Grimes

Electronic Theses and Dissertations

INTRODUCTION: Recently neurocognitive dysfunction has been linked to poor postural control in concussed athletes. While the detrimental effect of repetitive head impacts on cognitive function have been shown to mirror the effects of concussive injury, very little research has investigated the physical consequences of repetitive head impacts. PURPOSE: To observe the effects of RHI on postural control, both static and dynamic, in NCAA Division I athletes over the course of a single season. METHODS: 9 NCAA Division I football athletes (CON) were recruited from a single university as the experimental group, as well as 9 NCAA Division I baseball players …

An Exploration Of The Underlying Mechanisms Causing Spasticity In Young People With Cerebral Palsy, Alexis Carnes

Electronic Theses and Dissertations

Background and Objective(s): Spasticity is a common symptom experienced by individuals with cerebral palsy (CP). Spastic CP is often accompanied by hypertonia. Currently, there is a limited understanding of the contributions of spasticity to hypertonia which can in turn hinder the development of new rehabilitative measure to improve these conditions. Additionally, clinical evaluation of spasticity is limited to observational techniques such as the Ashworth scale. The purpose of this study was to compare differences in passive joint torque in the upper extremity between individuals with severe, spastic CP (MACS III-V) and healthy, age-matched controls at different speeds during passive stretching. …

The Effects Of Stimulant Medication On Reaction Time In Recreationally Active Individuals With Attention Deficit Hyperactivity Disorder, Nichole Ashley Lafortune

Electronic Theses and Dissertations

Context: Participants with Attention Deficit Hyperactivity Disorder (ADHD) have shown cognitive impairments that affect coordination, anticipation and planning. In the ADHD population, stimulant medication has shown to have beneficial outcomes for 75% of the people. Unfortunately, in most research, patients with ADHD are excluded and little is known about this population.

Purpose: Determine the effects of stimulant medication in recreationally active ADHD participants on reaction time.

Design: Cross-section between groups design

Methods: Participants were divided into two groups (ADHD and controls). Upon arrival to the Biomechanics Lab participants performed two tests, Mode A and Mode D on the Dynavision …

The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin

Electronic Theses and Dissertations

Background: Navicular drop can be defined as the distance the navicular tuberosity moves from a standing weight bearing to a standing neutral position, as the subtalar joint moves from a relaxed position to a neutral position. Navicular drop is an important measurement for clinicians used to describe foot function, pronation, and excessive movement seen in several pathologies. Objective: The purpose of this study is to see if navicular drop is influenced by mode or speed of locomotion, if it is will there be other influences such as the forefoot and heel soft tissue, and will those factors influence those measures. …
