Neurophysiological mechanisms of motor cortical modulation associated with bimanual movement
(University of Waterloo, 2008-09-11)The neural correlates of bilateral upper limb movement are poorly understood. It has been proposed that interhemispheric pathways contribute to the modulation of motor cortical excitability during bimanual movements, ... -
Novel Compliant Flooring Systems from Head to Toes: Influences on Early Compensatory Balance Reactions in Retirement-Home Dwelling Adults and on Impact Dynamics during Simulated Head Impacts
(University of Waterloo, 2011-06-21)The overall goal of my research was to advance our understanding of the potential for novel compliant flooring systems to reduce the risk for fall-related injuries in older adults, including fall-related traumatic brain ... -
Omega-3 Fatty Acid Blood Biomarkers Before and After Acute Fish Oil Supplementation in Men and Women
(University of Waterloo, 2007-09-17)Omega-3 fatty acids, particularly docosahexaenoic (DHA) and eicospentaenoic acid (EPA), are important mediators for cardiovascular disease, fetal/infant development, neurological disorders and inflammatory diseases. ... -
Oxygen uptake and blood flow kinetics following the onset of exercise in trained humans
(University of Waterloo, 2010-10-01)The main hypothesis of this thesis was that the regulation of oxygen uptake (VO2) kinetics at the onset of exercise in trained young men is linked to cardiovascular adaptations. Two studies were conducted to investigate ... -
Perceived Timing of Auditory and Inertial Cues During a Postural Perturbation In Younger and Older Adults
(University of Waterloo, 2015-10-05)How the perceived timing of sensory events changes during a fall is relatively unknown. Common anecdotal reports suggest that people often report distortions in their perception of time with very little recollection of ... -
Performance of a two-foot vertical jump: What is more important hip or knee dominance?
(University of Waterloo, 2010-12-22)Vertical jumping ability is an important fundamental skill for many athletic activities. The present work is focused on developing an understanding of the role of various movement strategies on vertical jump performance. ... -
Physical Activity Levels and Barriers to Exercise in Individuals with Low Bone Mineral Density
(University of Waterloo, 2013-09-27)Background: Fractures are a major health concern for older adults, especially for those with osteoporosis or low bone mineral density (BMD). Physical activity and exercise can be important self-management strategies for ... -
Physiological demands and ventilatory requirements during simulated large structure firefighting tasks
(University of Waterloo, 2007-09-25)The ability to measure the physiological demands and air requirements during simulated firefighting tasks while wearing full personal protective ensemble (PPE) and positive pressure self-contained breathing apparatus (SCBA) ... -
Postural Effects on Brain Blood Flow and Cognition in Heart Failure
(University of Waterloo, 2014-02-06)With the aging population on the rise, the prevalence of heart failure is expected to increase in the coming years. Heart failure is independently correlated with cognitive decline and has a negative impact on quality of ... -
Postural state modulation of cortical balance reactions
(University of Waterloo, 2019-09-25)Safe and effective walking is a crucial part of daily human life, but the number of injuries and resulting financial burden from falls during walking is increasing. As a result, it continues to be important to advance ... -
Premotor and prefrontal contributions to modulating upper limb somatosensory input into non-primary motor areas
(University of Waterloo, 2015-05-15)Upper limb motor control requires the use and integration of afferent somatosensory input from peripheral receptors to help plan and prepare movements. Cortical surface electroencephalography can be used to measure the ... -
Prolonged sitting, standing, and the sit-stand paradigm for office workers: An investigation into lumbar spine intervertebral joint load distribution
(University of Waterloo, 2014-08-27)Over the past 20 years, sit-stand workstations have become more and more prevalent in the office work environment. A sit-stand workstation is any workstation that allows the user to perform their office work in either a ... -
A psychophysical investigation of grip types with specific application to job rotation
(University of Waterloo, 2008-01-09)Job rotation is recommended to prevent musculoskeletal disorders (MSD). The premise is by involving different tissues a “working rest” for other tissues is created. The possible health benefits from this relief have not ... -
Quantification and Evaluation of Physical Shoulder Exposures in Police Mobile Data Terminal Operators
(University of Waterloo, 2009-09-30)Mobile police officers perform many of their daily duties within vehicles. Combined workspace inflexibility and prolonged driving exposure creates a risk for developing musculoskeletal issues. Limited research exists that ... -
Quantification of spine stability: Assessing the role of muscles and their links to eigenvalues and stability
(University of Waterloo, 2011-12-21)Approximately 50% - 80% of the population will experience disabling low back pain at some point in their life. Assessing and developing interventions based on “lumbar stability” and/or joint stiffness to reduce low back ... -
Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations
(University of Waterloo, 2014-04-30)Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of ... -
Quantifying and predicting upper limb capability and dysfunction of breast cancer survivors
(University of Waterloo, 2014-12-15)Breast cancer will affect one in every nine Canadian women during their lifetime. As diagnostic and treatment methods improve, survival rates are approaching 90%. However, an alarming 30-82% of survivors suffer from ... -
Quantifying the Effects of Humeral Elevation Angle, Plane of Elevation, and Motion Phase on 3D Shoulder Kinematics during Dynamic Humeral Movement in Multiple Vertical Planes
(University of Waterloo, 2012-03-09)A thorough understanding of typical shoulder motion is desirable for both clinicians and shoulder researchers. With this knowledge, comparisons between normal and special populations (e.g. athletic, working, elderly, ... -
