Structural And Functional Myocardial Adaptations To Task-Specific Epidural Stimulation In Chronic Spinal Cord Injury., Harley D. Ledbetter May 2022

Structural And Functional Myocardial Adaptations To Task-Specific Epidural Stimulation In Chronic Spinal Cord Injury., Harley D. Ledbetter

Electronic Theses and Dissertations

Cardiovascular disease is a leading cause of mortality, and this is especially true in individuals with spinal cord injury. Decreased systemic blood pressure leads to cardiac deconditioning, thought to be related to the increased cardiovascular morbidity and mortality in this population. This study investigates effects of myocardial loading from epidural stimulation in a group of individuals with spinal cord injury to understand how changes in preload and afterload could lead to beneficial myocardial remodeling. The study conducted echocardiograms to describe the myocardial changes after training with two different types of epidural stimulation intervention: one designed to facilitate movement (Voluntary) and …


Development And Evaluation Of A Body Weight Support Treadmill For Use With Locomotor Training On Pediatric Spinal Cord Injury Patients., Winston T Rauch Aug 2021

Development And Evaluation Of A Body Weight Support Treadmill For Use With Locomotor Training On Pediatric Spinal Cord Injury Patients., Winston T Rauch

Electronic Theses and Dissertations

The consequences of spinal cord injury (SCI) are devastating regardless of the age of a patient. When the injury occurs in children five years old or younger, however, the impact is magnified due to the inevitable development of scoliosis (96%) and hip dysplasia (57%) (Schottler et al., 2012). To reduce occurrence of these complications and improve the quality of life for these patients, specialized activity-based therapies such as locomotor training (LT) are being increasingly used to improve overall trunk control and muscle activity in the lower extremities (Harkema et al., 2012; Howland et al., 2014). The aim of this therapy …


Trunk And Respiratory Motor Control In Typically Developing Children And Its Implications In Children With Chronic Spinal Cord Injury., Goutam Singh May 2017

Trunk And Respiratory Motor Control In Typically Developing Children And Its Implications In Children With Chronic Spinal Cord Injury., Goutam Singh

Electronic Theses and Dissertations

Independent sitting is a major milestone and is also a prerequisite for optimal performance of activities of daily living (ADLs). Development of sitting posture control is a dynamic process involving control of degrees of freedom of head and trunk. Traditionally, trunk has been modeled as a single unit (segment). However, recent studies have suggested that it is made up multiple spinal units, controlled by a combination of trunk muscles. During typical development, posture control of trunk is different for different trunk segments. This motor development of trunk control is a complex process due to constant interaction between the nervous system …


Evaluating Cardiovascular Dysfunction During Increased Activity And Exercise Rehabilitation Following Incomplete Thoracic Spinal Cord Injury In The Adult Rat., Kathryn A. Harman Dec 2016

Evaluating Cardiovascular Dysfunction During Increased Activity And Exercise Rehabilitation Following Incomplete Thoracic Spinal Cord Injury In The Adult Rat., Kathryn A. Harman

Electronic Theses and Dissertations

Spinal cord injury (SCI) results in whole-body dysfunction. While the majority of SCI research is focused on improving locomotor function after injury, cardiovascular (CV) disease continues to be the leading cause of morbidity in the chronic SCI patient population. The combination of injury-induced destruction of autonomic pathways, maladaptive plasticity within lumbosacral circuits, and the progressive decline in physical fitness contribute to the poor CV status of SCI individuals. Currently, there is little emphasis on implementing appropriately-timed acute rehabilitation techniques aimed to curtail maladaptive remodeling and improve CV outcomes. Furthermore, no pre-clinical or clinical studies have investigated the most appropriate time-course …


A Phenomenological Study Of Anticipated Intimacy And Sexual Expression Needs Of Aging Male And Female Baby Boomers., Charles Shawn Oak Dec 2015

A Phenomenological Study Of Anticipated Intimacy And Sexual Expression Needs Of Aging Male And Female Baby Boomers., Charles Shawn Oak

Electronic Theses and Dissertations

The purpose of this study was to understand the phenomenon of how heterosexual Baby Boomers define and understand intimacy, sexual expression, along expectations and desires relating to their respective expressions across the lifespan through their individual experiences and reflections. A set of guiding questions were used in a hermeneutic phenomenological qualitative research design. Data was gathered from thirteen subjects (n=13) using the Rappaport Time Line (RTL) that was used to develop individualized semi-structured interviews and follow-up interviews that were professionally transcribed. These were coded to identify emergent themes. Results of the study provided insight into the phenomenon of how heterosexual …
