Chemical And Polymer Characterization Of The Potential Modes Of Degradation Of An Injectable Nucleus Pulposus Replacement Device, Antonio G. Abbondandolo
Chemical And Polymer Characterization Of The Potential Modes Of Degradation Of An Injectable Nucleus Pulposus Replacement Device, Antonio G. Abbondandolo
Theses and Dissertations
HYDRAFIL™ is a poly(vinyl alcohol)/poly(ethylene glycol)-based hydrogel nucleus pulposus replacement device that is injected in situ and has demonstrated efficacy in lowering the prevalence and pain associated with back. In this work, we developed a method to analyze HYDRAFIL™ polymer composition using (TGA) and characterized intermolecular bonding interactions within the hydrogel through (FTIR). To function as a permanent implant for nucleus pulposus replacement, HYDRAFIL™ must be stable when exposed to a multitude of degradation pathways, namely, thermal, chemical, and mechanical. We subjected HYDRAFIL™ to accelerated thermal and chemical degradation pathways and described compositional, physical and chemical property changes using a …
Effects Of Seat And Axle Position On Pain, Pathology, And Independence In Pediatric Manual Wheelchair Users With Spinal Cord Injury, Hannah Frank
Theses and Dissertations
Manual wheelchair (MWC) users with spinal cord injury (SCI) rely heavily on their upperextremities to complete daily occupations. Due to repetitive shoulder use during wheelchair mobility and propulsion, MWC users are at greater risk of shoulder pain and shoulder pathology, and thus decreased independence, and lower quality of life. The relative fit of the wheelchair and its parameters are critical and can further impact the user’s propulsion biomechanics. Parameters such as seat angle and axle position may put the user in detrimental shoulder positions for longer periods of time, impacting health outcomes even more. Although the effects of wheelchair setup …
Intermittent Theta Burst Stimulation: Application To Spinal Cord Injury Rehabilitation And Computational Modeling, Neil Mittal
Intermittent Theta Burst Stimulation: Application To Spinal Cord Injury Rehabilitation And Computational Modeling, Neil Mittal
Theses and Dissertations
Loss of motor function from spinal cord injuries (SCI) results in loss of independence. Rehabilitation efforts are targeted to enhance the ability to perform activities of daily living (ADLs), but outcomes from physical therapy alone are often insufficient. Neuromodulation techniques that induce neuroplasticity may push the limits on recovery. Neuromodulation by intermittent theta burst transcranial magnetic stimulation (iTBS) induces neuroplasticity by increasing corticomotor excitability, though this has most frequently been studied with motor targets and on individuals not in need of rehabilitation. Increased corticomotor excitability is associated with motor learning. The response to iTBS, however, is highly variable and unpredictable, …
The Effect Of Intermittent Theta Burst Stimulation On Biceps Corticomotor Excitability In Non-Impaired Individuals And Individuals With Tetraplegia, Blaize Majdic
Theses and Dissertations
Neuromodulation of the primary motor cortex (M1) in pair with physical therapy may be a promising method for improving motor outcomes after spinal cord injury (SCI). Increased excitability of the corticospinal motor pathways (i.e. corticomotor excitability) has shown to be associated with improved motor learning and skill acquisition. Intermittent theta burst stimulation (iTBS) is a form of non-invasive brain stimulation which can increase corticomotor excitability, as measured by an increase in the amplitude of motor evoked potentials (MEPs). However, the ability for iTBS to increase the corticomotor excitability of proximal muscles such as the biceps, and muscles affected by spinal …
Altering A Runner’S Foot Strike Using A Modified Elliptical Trainer, Daniel Shull
Altering A Runner’S Foot Strike Using A Modified Elliptical Trainer, Daniel Shull
Theses and Dissertations
One possible solution to common running related injuries is to transition runners from a rearfoot strike during initial contact to a midfoot strike. Natural rearfoot strike runners were studied to see if a modified elliptical trainer could be used to alter their running pattern to that of a midfoot strike runner. Their results were compared to subjects who ran on a non-modified elliptical trainer. After training on the modified elliptical trainer, subjects demonstrated a decrease in foot angle at initial contact when attempting to run with a midfoot strike. Training did not affect all kinetic metrics or stride frequency. However, …
Biomechanical Joint Demands And Functional Outcomes During Manual Wheelchair Use In Pediatric Patients With Spinal Cord Injury, Christine M. Aurit
Biomechanical Joint Demands And Functional Outcomes During Manual Wheelchair Use In Pediatric Patients With Spinal Cord Injury, Christine M. Aurit
Theses and Dissertations
The biomechanical demands of the upper extremities (UEs) during pediatric manual wheelchair (MWC) use have not been fully explored. Children who use MWCs for mobility engage in a range of functional activities that may place large biomechanical demands on the UEs leading to a high risk on overuse injuries. This study aims to analyze the kinematics and kinetics of pediatric manual wheelchair use during propulsion, starting, stopping and weight relief tasks. Fourteen pediatric patients with spinal cord injury were recruited and data were collected using a 14-camera Vicon MX motion analysis system (Oxford Metric Group, Oxford, UK) and a SmartWheel …
