Postural motor learning and the effects of age on practice-related improvements in compensatory posture control
(University of Waterloo, 2009-08-27)The purpose of this thesis was to examine the capacity for acquisition and retention of practice-related improvements in compensatory posture control and the nature of postural motor learning among healthy young and older ... -
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 ... -
Precision based guidelines for sub-maximal normalisation task selection for trunk extensor EMG
(Elsevier, 2017-07-01)Aim The object of this study was to quantify the contribution of sub-maximal normalisation to the overall variance of exposure parameters describing erector spinae (ES) activity, and to provide guidelines for task selection ... -
Predicting Cervical Spine Compression and Shear in Helicopter Helmeted Conditions Using Artificial Neural Networks
(University of Waterloo, 2021-08-27)Introduction: Military helicopter pilots around the globe experience a high prevalence of neck pain. The requirement for pilots to use night vision goggles (NVGs) has been linked to increases in neck pain and injury ... -
The Prediction of Nociceptive Neural Activity in Passive Tissues following Lumbar Spine Flexion
(University of Waterloo, 2021-11-26)Low back pain is a costly and debilitating disorder; however, most cases are categorized as being non-specific: low back pain without an identifiable origin or cause. Non-specific low back pain can be broadly considered ... -
Prediction of Oxygen Uptake and its Dynamics by Wearable Sensors During Activities of Daily Living
(University of Waterloo, 2016-12-21)The evaluation of the aerobic response to a new energetic demand provides valuable information regarding the functional capabilities of the aerobic system. Abnormal, or impaired aerobic responses may occur before the ... -
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 ... -
Prevalence and Determinants of Poor Food Intake of Residents Living in Long-Term Care
(Elsevier, 2017-06-28)Poor food intake is known to lead to malnutrition in long-term care homes (LTCH), yet multilevel determinants of food intake are not fully understood, hampering development of interventions that can maintain the nutritional ... -
A procedure for determining parameters of a simplified ligament model
(Elsevier, 2017-11-03)A previous mathematical model of ligament force-generation treated their behavior as a population of collagen fibres arranged in parallel. When damage was ignored in this model, an expression for ligament force in terms ... -
Progressive Disc Herniation: An investigation of the mechanism using histochemical and microscopic techniques
(University of Waterloo, 2006)Abstract Background: The process that involves the migration of the nucleus pulposus from the innermost annular layers and culminates with the final extrusion of the nucleus has been limited to a few studies. This ... -
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 ... -
Protection against high fat diet induced obesity in mdx mice: is sarcolipin involved?
(University of Waterloo, 2018-02-15)Sarcolipin (SLN) is a 31 amino acid proteolipid and one of the regulators of sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) pumps. Previous research has shown that sarcolipin levels in muscles from wild type (WT) mice ... -
Protective Responses during a Sideways Fall: Effects of Secondary Tasks
(University of Waterloo, 2006)Falls and hip fractures are a major public health problem among the elderly. In addition to bone strength, sideways falls and direct hip impact are important determinants for hip fracture. However, few falls actually ... -
Psychometric correlates of multisensory integration as potential predictors of cybersickness in virtual reality
(University of Waterloo, 2019-08-16)Humans are constantly presented with rich sensory information through the environment that the central nervous system (CNS) must process to form a coherent perception of the world. While the CNS may be efficient in doing ... -
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 ... -
“Putting Quality Food on the Tray”: Assessing Patients’ Expectations and Experiences of Meals Served in Sixteen Ontario Hospitals
(University of Waterloo, 2020-09-29)Background: Malnutrition is prevalent among hospital patients and occurs in up to 45% of Canadian medical and surgical patients. Hospital malnutrition is associated with detrimental outcomes for patients, such as further ... -
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 ... -
