The Association between Fractures, Posture and Physical Performance Measures in Women Over the Age of 65
(University of Waterloo, 2016-10-06)Background Information: Vertebral fractures are a common type of osteoporotic fracture, associated with increased morbidity and mortality. An accumulation of vertebral fractures may lead to postural changes including ... -
Attention and Age-Related Components of Visual-Tactile Modulation of Somatosensory Cortex and Motor Implications
(University of Waterloo, 2010-06-16)Successful interaction with the external world requires continual sensory detection, sensorimotor translations and goal-directed motor execution. Attention to task-relevant stimulation can facilitate sensory detection and ... -
Automated Histological Analysis System for Quantifying Microstructural Damage Accumulation to the Annulus Fibrosus
(Kitchener-Waterloo Vision and Imaging Society, 2016)In this paper, we proposed an automated histological analysis system for quantifying microstructural damage accumulation to the annulus fibrosus. This system takes in a digital histology image and uses Gaussian mixture ... -
Autophagy Regulates the NOTCH Signaling Pathway During Skeletal Muscle Cell Differentiation
(University of Waterloo, 2021-06-01)Research has indicated a crucial role for autophagy during skeletal muscle differentiation. More so, the inhibition of autophagy using 3MA (3-methyladenine), CQ (chloroquine), and shRNA against Atg7 has been shown to impair ... -
Axial twist loading of the spine: Modulators of injury mechanisms and the potential for pain generation.
(University of Waterloo, 2008-05-26)There are several reasons to research the effects of axial twist exposures and the resulting loading on the spine. The lack of consensus from the limited work that has previously examined the role of axial twist moments ... -
Axial twist of the lumbar spine: Mechanical responses to twisted postures and potential factors for workplace injury
(University of Waterloo, 2017-08-24)While a link between magnitudes of spinal axial twist motions and the various modes of associated injury, pain reporting, and lost time claims has been tentatively established, there is need for greater investigation and ... -
Bioelectrical Impedance Analysis Overestimates Fat-Free Mass in Breast Cancer Patients Undergoing Treatment
(Wiley, 2020-12)Background: Bioelectrical impedance analysis (BIA) is commonly used to assess fat-free mass (FFM) and fat mass (FM) in breast cancer patients. However, because of the prevalence of overweight, obesity and variable hydration ... -
Biomechanical Assessment of Cycling Helmets: the Influence of Headform and Impact Velocity based on Cycling Collisions associated with Injury Claims
(University of Waterloo, 2015-01-23)The goal of my thesis was to fill some of the gaps in knowledge about cyclist/motor vehicle collisions and testing guidelines for cycling helmets. Cycling collisions with motor vehicles represent a problem for the Canadian ... -
A biomechanical investigation into the link between simulated job static strength and psychophysical strength: Do they share a “weakest link” relationship?
(University of Waterloo, 2011-01-17)Maximum voluntary forces and psychophysically acceptable forces are often used to set force guidelines for exertions as a means to protect against overexertion injuries in the workplace. The focus of this dissertation was ... -
Biomechanical Predictors of Functionally Induced Low Back Pain, Acute Response to Prolonged Standing Exposure, and Impact of a Stabilization-Based Clinical Exercise Intervention
(University of Waterloo, 2009-07-24)Purpose: Biomechanical differences between people with low back pain (LBP) and healthy controls have been shown previously. LBP has been associated with standing postures in occupational settings. A transient pain-generating ... -
A Biomechanical-Biochemical Hypothesis for the Role of Collagen in Injury
(University of Waterloo, 2022-07-25)Low back pain affects 80% of the population at some point in their lives and is the most common musculoskeletal complaint for workplace injuries. Further, it presents as episodic, with sufferers typically experiencing ... -
Biomechanics of Lateral Hip Impacts: the Influence of Measurement Technique and Contact Area
(University of Waterloo, 2014-02-21)The experiments presented in this thesis provide novel insight into two scarcely studied areas in the field of lateral hip impact biomechanics. The high energy nature of hip impacts requires high sampling rates for accurate ... -
Breast cancer survivor functional changes immediately following treatment: quantifying mechanisms of strength deficits and compensatory kinematic and muscular strategy adaptations
(University of Waterloo, 2021-11-04)Breast cancer is prevalent among Canadian women, but treatments may cause functional impairments among survivors. Over 22,000 Canadian women join the survivor population yearly (Brenner et al., 2020). Despite this substantial ... -
Bridging the gap between physical activity evidence and practice for older adults with osteoporosis and frailty
(University of Waterloo, 2021-12-09)Exercise prescriptions that include moderate or high intensity progressive, resistance training, and functional and balance training may improve physical functioning and disability outcomes and prevent falls in older adults ... -
Build better bones with exercise (B3E pilot trial): results of a feasibility study of a multicenter randomized controlled trial of 12 months of home exercise in older women with vertebral fracture
(Springer, 2018-08-08)Summary We pilot-tested a trial of home exercise on individuals with osteoporosis and spine fracture. Our target enrollment was met, though it took longer than expected. Participants stayed in the study and completed ... -
Butylated hydroxytoluene can protect polyunsaturated fatty acids in dried blood spots from degradation for up to 8 weeks at room temperature
(BioMed Central, 2013-02-20)Background: Dried blood spots (DBS) from fingertip prick blood can enable high throughput fatty acid profiling but may be prone to lipid peroxidation during storage. The use of butylated hydroxytoluene (BHT) on chromatography ... -
Can Altering Hip Joint Fluid Volume and Intra-Capsular Pressure Influence Muscle Activation Patterns? Neuromuscular Implications on Clinical Practice
(University of Waterloo, 2011-05-03)Although the integrated relationship that exists between the lumbar spine and hip joints is frequently acknowledged in scientific journals and by medical professionals, specific functional and injury relationships, are ... -
Cardiac motion simulation in cadavers and carotid artery longitudinal wall behaviour
(University of Waterloo, 2023-12-21)Carotid artery longitudinal motion (CALM) is a bidirectional, multiphasic motion of the intima-media complex of the common carotid artery (CCA) wall. This motion has exhibited changes with aging, elevated cardiovascular ... -
Cardiovascular Deconditioning Resulting from 28-hour Bed-rest and the Efficacy of the Fluid Loading Countermeasure
(University of Waterloo, 2010-01-11)This study tested the hypotheses that 1) 28h head-down bed-rest (HDBR) would result in significant hypovolemia and cardiovascular deconditioning, and that 2) NASA’s fluid loading protocol (ingestion of 15 ml/kg water with ... -
