The Influence Of Autonomic Function On Pain Modulation Before And After Exercise And Cognitive Task In Fibromyalgia, Abdulaziz Awali
The Influence Of Autonomic Function On Pain Modulation Before And After Exercise And Cognitive Task In Fibromyalgia, Abdulaziz Awali
Dissertations (1934 -)
Fibromyalgia (FM) is a chronic pain condition characterized by widespread pain. People with FM have alterations in autonomic function compared to healthy individuals. Exercise can decrease pain in people with FM, however some people with FM experience pain exacerbation when initiating exercise. Whether variability in pain at rest and following exercise is related to altered autonomic function, including the potential implications with other stressful events such as mental math, is not known. This dissertation aimed at investigating: 1) the relation between cardiovascular autonomic function and central pain facilitation and inhibition, measured by temporal summation of pain (TS) and conditioned pain …
Pain Modulatory Effects Of Exercise In Chronic Pain, Giovanni Berardi
Pain Modulatory Effects Of Exercise In Chronic Pain, Giovanni Berardi
Dissertations (1934 -)
Exercise training is recommended as a first-line treatment in the management of fibromyalgia due to its ability to improve symptoms and function. However, many with fibromyalgia report limited tolerance to exercise due to exacerbation of pain and fatigue during and following participation of a single bout of exercise. The purpose of this dissertation was to determine the influence of contraction type on local and systemic experimental pain sensitivity, performance fatigue, and perceived pain and fatigue during exercise and through recovery in people with and without fibromyalgia.Experimental and perceived pain were measured before and after a single bout of submaximal intermittent …
Experimental & Simulation Approaches To Study Neuromuscular Control In People With Chronic Ankle Instability, Hoon Kim
Dissertations (1934 -)
Ankle sprains are among the most common musculoskeletal injuries, and up to 70% of people who sprain their ankles develop chronic ankle instability (CAI). Moreover, people who develop CAI have a significantly higher risk of developing ankle osteoarthritis. Recent research has identified neuromuscular deficits that may be responsible for the high recurrence rates of ankle sprains and for the progression towards ankle osteoarthritis in people with CAI. Unfortunately, current rehabilitation strategies are not completely successful because the mechanisms responsible for these deficits are not fully elucidated. Therefore, the purpose of this dissertation was to investigate individual muscle forces and force …
Submaximal Isometric Force Steadiness In People With Multiple Sclerosis Under Single And Dual Task Conditions, Sheri Bunyan
Submaximal Isometric Force Steadiness In People With Multiple Sclerosis Under Single And Dual Task Conditions, Sheri Bunyan
Dissertations (1934 -)
Activities of daily living require steady, non-fatiguing, isometric muscular contractions to maintain postural control and stabilize body segments to facilitate interaction with the environment. Furthermore, typical activities often require simultaneous performance of cognitive and motor tasks. This may challenge people with multiple sclerosis, a chronic neurodegenerative disease of the central nervous system associated with motor and cognitive impairments. Despite functional relevance, isometric force steadiness in both the upper and lower extremities has not been explored in this population. Additionally, dual task experiments in multiple sclerosis have primarily used gait, a dynamic activity, as the motor task. Thus, the purpose of …
The Impact Of Isometric Exercise On Somatosensory Processing In People With Or Without Chronic Pain, Ali Mohammed Alsouhibani
The Impact Of Isometric Exercise On Somatosensory Processing In People With Or Without Chronic Pain, Ali Mohammed Alsouhibani
Dissertations (1934 -)
Despite an increase in our understanding of the pathomechanisms of chronic pain and the advancement of new treatments, pharmacological management of chronic pain remains poor. This presents the need for non-pharmacological treatments and understanding their efficacy and mechanisms in managing pain. The purpose of this dissertation was to examine the effects of isometric exercise on the somatosensory system and other biopsychosocial aspects related to pain in individuals with and without fibromyalgia. The first aim was to determine whether isometric exercise improves pain inhibitory mechanisms and vibration sense. The second aim was to determine what biopsychosocial factors influence pain relief following …
Change In Bone Mineral Density Among High Frequency Apheresis Blood Donors, Walter Bialkowski
Change In Bone Mineral Density Among High Frequency Apheresis Blood Donors, Walter Bialkowski
Dissertations (1934 -)
Exposure to citrate anticoagulant during apheresis blood donation induces significant decreases in serum ionized calcium with subsequent perturbations to parathyroid hormone, vitamin D, and markers of bone remodeling. Cross-sectional studies of bone mineral density (BMD) among apheresis donors exhibit conflicting results. Resolving the potential impact of the highest apheresis donation frequency represents a significant knowledge gap in ensuring adequate protections for volunteer apheresis blood donors. ALTRUYST (NCT02655055) was a randomized, longitudinal, controlled clinical trial designed to determine if repeated exposure to citrate through apheresis donation reduces BMD. Male donors, 18-65 years of age with no more than five previous apheresis …
Neuromuscular Function In Women Postpartum, Rita Deering
Neuromuscular Function In Women Postpartum, Rita Deering
Dissertations (1934 -)
Efficient abdominal muscle function is important for functional mobility in men and women, and dysfunction of these muscles has been associated with impaired function such as low back pain. This dissertation explored abdominal muscle function in healthy young men and young women who have never been pregnant (nulligravid). As pregnancy and child birth also impact the tissues of the abdominal wall, this dissertation will also explore abdominal muscle function in postpartum women. This dissertation involved three primary aims. Aim1 compared abdominal muscle function and experimental pain perception in males and nulligravid females. Maximal strength over a range of trunk angles, …
Mechanisms Of Isometric Exercise-Induced Hypoalgesia In Young And Older Adults, Kathy J. Lemley
Mechanisms Of Isometric Exercise-Induced Hypoalgesia In Young And Older Adults, Kathy J. Lemley
Dissertations (1934 -)
Pain reduction following exercise (exercise-induced hypoalgesia; EIH) is well-established in young adults. Specific to isometric exercise, the greatest EIH follows low intensity contractions held for long duration. The EIH response of older adults is not known; and the mechanisms for EIH are unclear at any age. This dissertation aimed to address these unknowns through a series of three studies. In study one, repeatability of pressure pain reports (pain threshold and pain ratings) was assessed in healthy older adults, including the impact of psychological factors. Pain reports, measured before and after quiet rest, did not change following quiet rest. Higher state …
Muscle Fatigue And Motor Output Variability With Acute Stress In Healthy Young Adults And Veterans With Posttraumatic Stress Disorder, Manda Linea Keller
Muscle Fatigue And Motor Output Variability With Acute Stress In Healthy Young Adults And Veterans With Posttraumatic Stress Disorder, Manda Linea Keller
Dissertations (1934 -)
Acute stress can alter motor performance differently for men and women. The first aim of this dissertation addresses possible causes for the sex difference in the motor response of a low-intensity fatiguing contraction of the elbow flexor muscles to an acute stressor (difficult mental math) in young, healthy adults. Muscle fatigue increased for men and women when exposed to the stressor, but impairment was more prominent for the women. This work showed that fatigue in the central nervous system, specifically in cortical motor and premotor areas, as well as relaxation rates of the muscle (quantified with cortical stimulation) were not …
