Developing A Methodology For Evaluating Postural Control And Functional Ability In Children With Cerebral Palsy, Abigail Schoppa

Honors College Theses

Background: Cerebral Palsy (CP) is a non-progressive group of disorders that interferes with postural control and gross motor function (GMF). The purpose of this study was to develop a methodology to evaluate and link postural control and functional ability by identifying the best measures to use.

Methods: For this study, children between the ages of 12 and 22 who have CP and a Gross Motor Function Classification System level I to III were recruited. They performed a series of gross motor tests from the BOT-2 while standing on a force plate to record their center of pressure (COP) movement. Several …

Effects Of Occupational Tasks And Personal Protective Equipment On Static And Functional Balance Among Career Firefighters, Petra Kis

College of Graduate Studies: Theses & Dissertations

BACKGROUND: Musculoskeletal injuries are commonly incurred on the fireground among firefighters. Most injuries are attributable to overexertion, fall, jump, slip, and trip mechanisms. These injuries may be caused by many factors, including the independent and collective effects of wearing personal protective equipment (PPE) and the fatigue induced by performing occupational tasks. Therefore, the purpose of this study was to investigate the effect of PPE and fire suppression tasks on static and functional balance among firefighters. METHODS: 32 healthy male career structural firefighters (Age: 31.8±9.5 yr) volunteered for this study. Static and Functional Balance Tests (FBT) were performed in …

The Development Of A Novel Throwing Assessment For Children With Cerebral Palsy, Cory Cribb

College of Graduate Studies: Theses & Dissertations

Introduction: Cerebral palsy is one of childhood's most common developmental disabilities. Cerebral palsy leads to dysfunction in the upper extremities due to symptoms such as low muscle power, spasticity, and increased tone. A modified throwing assessment was constructed to examine throwing performance as a measure of upper extremity function. Purpose: To determine if the modified throwing assessment is a reliable measure of throwing performance and if the modified throwing assessment is a valid measure of upper extremity power in children with CP. Methods: The study employed a test-retest design aimed at determining the reliability of a modified throwing assessment. Seven …

The Effects Of A Mirror On Cognitive Strategy And Performance Of A Muscular Endurance Task, Brianna M. Simmons

College of Graduate Studies: Theses & Dissertations

Context: Mirrors are common-place in exercise facilities, however, the effect the mirror has on cognitive strategy (i.e., where the mind’s at) and performance time has not been examined in a muscular endurance task (i.e., a wall sit). Objective: To determine, (1) the mirror’s effect on cognitive state during a wall sit to volitional exhaustion, (2) the mirror's effect on time to volitional exhaustion during a wall sit, and (3) the mirror’s effect on the participant’s rating of perceived exertion (RPE) during the wall sit. Design: Repeated measures design. Setting: Indoor exercise facility. Participants: Twenty resistance-trained Georgia Southern University Students (9 …

Current Recommendations For Lower Body Aerobic Exercise In Chronic Unilateral Stroke - A Systematic Review, Jordan N. Brown

College of Graduate Studies: Theses & Dissertations

Background: Chronic stroke patients (i.e., > six months since the onset of stroke) continue to experience persistent gait complications. Once formal physical therapy concludes, exercise professionals can implement exercise interventions designed to improve quality of life and reduce risk of secondary stroke. This systematic review aimed to evaluate whether lower-body aerobic exercise transferred to gait improvements in chronic unilateral stroke. Methods: An electronic search of the following databases were undertaken: MEDLINE, CINHAL, Ovid, and SPORTdiscus. Two independent reviewers selected articles using predetermined inclusion criteria: adults (i.e., >18 years old) who suffered from a chronic unilateral stroke. Additionally, all included studies were …

Effects Of Active Sitting On Typing And Reading Task Productivity, Claire Doroff

Honors College Theses

Increased sedentary behavior and reduced physical activity among children and adults has led to the advent of various active devices to combat these behaviors. Active sitting, consisting of modified chairs or stability balls, allows the body to stay dynamic while seated. While research has evaluated the health benefits of active sitting, minimal research has shown the effects of active sitting on productivity in adult populations. PURPOSE: The purpose was to evaluate the effects of various chairs (active versus non-active) on typing and reading task productivity. METHODS: Twenty adult participants performed typing and reading tasks for 10-minutes while sitting …

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

College of Graduate Studies: Theses & 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 …

Assessment Of Anti-Saccades Within 24 To 48 Hours Post-Concussion, Nathan D'Amico

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: Oculomotor control dysfunction is present in about 90% of concussed athletes, with anti-saccades being the most prominent. PURPOSE: To investigate anti-saccades, reflexive gaze deviations from a fixed point or area of interest, between NCAA Division I athletes 24 to 48 hours post-concussion (PC) and healthy, matched controls (MC). METHODS: 10 PC (4 female, 6 male; age: 18.9 ± 0.9 years) and 10 MC (4 female, 6 male; age: 18.3 ± 0.6 years) wore a monocular eye tracker (240Hz) while performing 2 trials of the 60-second WiiFit Soccer Heading game. During play, participants were instructed to not deviate their gaze …
