Hip & Spine Mechanics - Understanding the linkage from several perspectives of injury mechanisms to rehabilitation using biomechanical modelling
(University of Waterloo, 2020-01-08)One recent megatrend in medicine is that of “precision medicine” whereby a precise diagnosis leads to a precise intervention for superior results. This thesis was undertaken to enhance the understanding of spine and hip ... -
History-Dependent Changes to the Structure, Properties, and Function of the Cartilaginous Endplate
(University of Waterloo, 2023-04-12)The performance of manual lifting is associated with 33-51% of incidental low back injuries in work, leisure, and sport/exercise contexts. To effectively prevent low back injuries and evaluate the risk of occurrence, ... -
How does emotion affect the way we walk?
(University of Waterloo, 2022-09-22)Gait, the way that human beings walk, is a large component and indicator of health in both young and older adults. Gait has been used in the past to identify injury and fall risk, progression of diseases and is used as a ... -
Hsp70 Protects Against Peroxynitrite-Induced Inactivation of SERCA2a by Preventing Protein Oxidation and Aggregation
(University of Waterloo, 2008-09-18)The purpose of this study was to examine the effects of exogenous peroxynitrite (ONOO-) on the cardiac isoform of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA2a) and to determine if overexpression of heat shock ... -
Hydrogen peroxide is vasoactive in the mesenteric arteries of spontaneously hypertensive rats
(University of Waterloo, 2008-05-22)It is well established that hypertension decreases endothelium-dependent vasomotor function, partially by excessive generation and reduced scavenging of reactive oxygen species (ROS). Nevertheless, at appropriate levels, ... -
Identification and characterization of a novel microsomal enzyme involved in cardiolipin synthesis and remodeling
(University of Waterloo, 2018-05-17)Cardiolipin (CL) is a specialized dimeric phospholipid predominantly found in the inner mitochondrial membrane in eukaryotes. Following de novo synthesis, the acyl chains of CL are remodeled in a manner that is tissue- and ... -
Identifying Determinants of Performance for Females Completing a Paramedic Physical Employment Test
(University of Waterloo, 2023-06-02)Background: Sex disparities exist in employment and injury rates in the paramedic sector. Low success rates among females attempting physical employment standards could explain the elevated injury risk among female paramedics. ... -
An Identity Theory and Social Cognitive Theory Examination of the Role of Identity in Health Behaviour and Behavioural Regulation
(University of Waterloo, 2005)The self has been identified as the ?psychological apparatus that allows individuals to think consciously about themselves? (Leary & Price Tangney, 2003, p. 8). Further, the self has been identified as a worthwhile ... -
The impact of compressive force magnitude on the in vitro neutral zone range and passive stiffness during a flexion–extension range of motion test
(Taylor & Francis, 2015-02-23)The objective of this work was to examine the influence of compressive force magnitude on a functional spinal unit’s (FSU) flexion–extension neutral zone measured during pure moment (PM) tests. Each porcine cervical FSU ... -
The Impact of Training on Naming and Producing Actions to Novel Objects
(University of Waterloo, 2010-05-06)Visual object similarity, action similarity and semantic information are believed to influence both object naming and action production. The Naming and Action Model (NAM) developed by Yoon, Heinke, and Humphreys (2002) ... -
Impairments in glucose and lipid metabolism in breast cancer patients
(University of Waterloo, 2013-01-08)BACKGROUND: Breast cancer patients typically present with unhealthy body composition (high fat mass and low muscularity) near diagnosis. These body composition characteristics often worsen during treatment and ultimately ... -
In Search of Manual Asymmetries in Aging during Performance of Activities of Daily Living: Does Upper Limb Performance Become More Symmetric with Age?
(University of Waterloo, 2013-09-27)Introduction: A common disorder arising most frequently after a left hemisphere stroke is limb apraxia. Limb apraxia is a deficit of skilled movement, such as performance of activities of daily living (ADLs), that is not ... -
IN VITRO AND IN VIVO BIOMECHANICAL INVESTIGATION OF THE CLINICAL PRACTICE OF DISC PROLAPSE PREVENTION AND REHABILITATION
(University of Waterloo, 2007-09-10)Underlying this thesis is the McKenzie school of thought, a physiotherapy approach that teaches clinicians to recommend particular exercises to their clients in an attempt to accelerate recovery/ prevent recurrence of disc ... -
Incorporating Musculoskeletal Disorder Prevention into Organizations’ Management Systems
(University of Waterloo, 2015-04-09)Musculoskeletal disorders (MSD) – for example, low back pain or shoulder tendinitis -are prevalent disorders with significant economic burdens to organizations and personal costs to workers. The approaches to prevent these ... -
Individuality in balance control: Using conventional analytical & machine learning approaches to reveal person-specific differences in standing balance control.
(University of Waterloo, 2023-08-31)The balance control system ensures that humans can perform tasks in a variety of postures despite bipedal stance being inherently unstable. It manages this instability by producing motor outputs that are appropriate to ... -
The influence of acute aerobic exercise on excitability and rapid plasticity in the primary motor cortex
(University of Waterloo, 2016-04-22)The aim of this thesis was to explore the influence of a single session of aerobic exercise on excitability changes and markers of short-term plasticity in the human primary motor cortex (M1). To that end, this thesis ... -
