The effect of concussion history on relevancy-based gating of visual and tactile stimuli
(University of Waterloo, 2018-01-23)At the cortical level, incoming sensory inputs are subject to interruption as they are transmitted to modality-specific cortical areas, in order to prevent excessive processing of task-irrelevant sensory information and ... -
Effect of Cyclic and Sustained Squatting Exposures on Hemodynamics and Subsequent Changes in Lower Limb Jumping Mechanics
(University of Waterloo, 2019-07-29)Occupational exposure to high knee flexion postures such as squatting or kneeling is associated with an increased risk of developing knee osteoarthritis. The exact mechanisms behind the increased risk are currently unknown. ... -
Effect of Degrees of Freedom on Effort and Rate of Fatigue Accumulation During the Supine Chest Press
(University of Waterloo, 2017-05-19)INTRODUCTION For workplace tool design and exercise equipment design alike, the number of the degrees of freedom to be controlled in a tool or machine has been shown to affect the biological response of the user. Studies ... -
The effect of different manual task simulation methods on hand and forearm demand estimates
(University of Waterloo, 2009-08-28)The force exerted during manual tasks is a dominant risk factor for upper-limb musculoskeletal disorders. To identify tasks that may lead to fatigue over a shift, or increase the risk of injury, the demands placed on the ... -
The effect of different methods to identify, and scenarios used to address energy intake misestimation on dietary patterns derived by cluster analysis
(BioMed Central, 2021-05-08)Background: All self-reported dietary intake data are characterized by measurement error, and validation studies indicate that the estimation of energy intake (EI) is particularly affected. Methods: Using self-reported ... -
The Effect of Dual-Tasking on Information Processing in Contact Sport Athletes: Examining the long-term effects of Self-reported Concussion
(University of Waterloo, 2015-09-24)Objective: Concussions have been linked to deficits in executive functions including, memory and attention, and oculomotor dysfunction, all of which are required to play safely and successfully at an elite level. The goal ... -
The Effect of Familiarity and Complexity of Environments, and Mode of Wayfinding on Gaze and Memory
(University of Waterloo, 2015-01-21)Whether we travel the well-known route to work or unfamiliar streets in a new city, we use wayfinding in order to determine and follow a route to get to our destination. Wayfinding is dependent on cognitive processes, ... -
The effect of interior bezel presence and width on magnitude judgement
(Canadian Human-Computer Communications Society, 2014-05)Large displays are often constructed by tiling multiple small displays, creating visual discontinuities from inner bezels that may affect human perception of data. Our work investigates how bezels impact magnitude judgement, ... -
The effect of limited hip mobility on the lumbar spine in a young adult population
(University of Waterloo, 2010-08-26)Limited hip mobility is known to affect the lumbar spine. Much of the previous research has utilized a participant population whose hip mobility is compromised due to arthritic or neurological dysfunctions. Such aetiologies ... -
The Effect of Minimal Footwear and Midsole Stiffness on Lower Limb Kinematics and Kinetics in Novice and Trained Runners
(University of Waterloo, 2013-09-05)Background: The most common injuries in new or novice runners include medial tibial stress syndrome and patellofemoral pain syndrome; both overuse injuries. It is known that novice runners use a rearfoot strike pattern 98% ... -
The Effect of Mitochondrial Biogenesis on Apoptotic Susceptibility in L6 Myoblasts
(University of Waterloo, 2010-09-27)Mitochondria play an essential role in cell metabolism as well as apoptotic signaling. Chronic endurance exercise has been shown to increase mitochondrial content in skeletal muscle. Interestingly, endurance exercise has ... -
Effect of obesity on knee joint biomechanics during gait in young adults
(Taylor & Francis, 2016-04-26)While there are many comorbidities associated with obesity, one of the more poorly understood is knee osteoarthritis through obesity. The purpose of this study was to compare the kinematics and kinetics of gait and cumulative ... -
The effect of portable HEPA filter air cleaners on indoor PM2.5 concentrations and second hand tobacco smoke exposure among pregnant women in Ulaanbaatar, Mongolia: The UGAAR randomized controlled trial
(Elsevier, 2018-02-15)Background Portable HEPA filter air cleaners can reduce indoor fine particulate matter (PM2.5), but their use has not been adequately evaluated in high pollution settings. We assessed air cleaner effectiveness in reducing ... -
The effect of price and retail availability on the use of illegal and legal non-medical cannabis in Canada and the United States
(University of Waterloo, 2021-08-18)Background – Cannabis policy has liberalized in North America over recent decades. In October 2018, Canada legalized non-medical cannabis. The regulatory framework includes some similarities with jurisdiction in the United ... -
The Effect of Religious Participation on Cognitive Function in Middle- and Old-Aged Adults: A Sequential Explanatory Mixed Methods Study of the Canadian Longitudinal Study on Aging
(University of Waterloo, 2019-12-05)Background: Preserving cognitive health is a crucial aspect of successful aging. Atypical cognitive decline is linked to the onset of dementia disorders such as Alzheimer’s disease. Even normal cognitive deterioration can ... -
The Effect of Salient and Neutral Distractors on Hand-Eye Coordination during Goal-Directed Reaching
(University of Waterloo, 2018-10-22)OBJECTIVE: The successful perception of a target location is critical for everyday reaching behaviours. Visually-guided goal-directed action involves successful coordination of both eyes and upper limb movement execution. ... -
The Effect of Spironolactone on Cerebral Blood Flow and Cognition
(University of Waterloo, 2018-03-23)Hypertension and arterial stiffness are associated with structural and functional changes in cerebral circulation and cognitive function, but based on existing evidence the effects are potentially reversible by spironolactone ... -
The Effect of Working Memory on Corticospinal Excitability
(University of Waterloo, 2020-10-26)Skilled behavior is dependent upon the ability to extract and integrate sensory afference into appropriate output from motor cortex. This process is dynamic with executive control, guided by declarative knowledge (i.e. ... -
