Spine Biomechanics of Prolonged Sitting: Exploring the Effect Chair Features, Walking Breaks and Spine Manipulation have on Posture and Perceived Pain in Men and Women.
(University of Waterloo, 2015-03-03)Purpose: Prolonged sitting while working in an office has become a standard function in our society. While seated postures do conserve energy and permit a worker to focus on a task, the posture also involves a significant ... -
Stabilization Strategies of the Lumbar Spine in Vivo
(University of Waterloo, 2002)In developing a method of quantifying stability in the lumbar spine Cholewicki and McGill (1996) have also broached the notion of sufficient stability, where too much stiffness (and stability) would hinder motion. Thus ... -
Statistical Power in Ergonomic Intervention Studies
(University of Waterloo, 2010-04-21)As awareness of the costs of workplace injury and illness continues to grow, there has been an increased demand for effective ergonomic interventions to reduce the prevalence of musculoskeletal disorders (MSDs). The goal ... -
Strategies and Adaptations Seen with Unilateral Lower Limb Weighting during Level Ground Walking and Obstacle Clearance Tasks
(University of Waterloo, 2010-02-17)Abstract: Previous lower limb weighting studies have placed a load on the legs bilaterally and tested different placement locations. It was previously determined that kinematic changes occur with greater masses and at ... -
Strategies Utilized while Minimizing Ankle Motion Bilaterally and Unilaterally during Level Ground Walking and Obstacle Clearance Tasks
(University of Waterloo, 2010-08-30)A great deal of research has been done on the adaptive strategies of individuals who have been affected by a gait altering ailment, but there is little research on the adaptive strategies to imposed restrictions in the ... -
Studies on the Physiology and Glucose Metabolism of 14-16-Month-Old Female RTSAKO Mice
(University of Waterloo, 2020-09-01)Obesity is a global epidemic. Characterized by an imbalance between energy intake and expenditure, the metabolic and physiological dysfunctions that it yields can result in other diseases such as diabetes. Although several ... -
The suitability and consequence of renal tubule specific adipose triglyceride lipase ablation for the study of targeted lipid accumulation in the kidney
(University of Waterloo, 2015-05-15)Circulating non-esterified fatty acids (NEFA) rise during fasting and are taken up by the kidneys, either directly from the plasma or during re-uptake of albumin from glomerular filtrate, and are stored as triacylglycerol ... -
Supramaximal Testing to Confirm the Achievement of V̇O2max in Acute Hypoxia
(University of Waterloo, 2023-01-23)Incremental exercise tests are often used to quantify an individual’s maximal oxygen uptake (V̇O2max). To confirm V̇O2max, a bout of supramaximal exercise can be performed after maximal exercise and if V̇O2 is within the ... -
Tailored Exercise For Fall And Fracture Prevention In Older Adults: A Family Health Team Approach
(University of Waterloo, 2012-09-27)Background: Exercise interventions reduce falls in older adults. Methods for enhancing uptake and adherence to exercise programs in at-risk individuals are needed. Objectives: This pilot study evaluated feasibility of ... -
Theta-burst rTMS over SI modulates tactile perception on the hand
(University of Waterloo, 2011-05-18)Fine motor control of the hand relies on intact somatosensory integration and feedback. Impaired hand movements are observed in patient groups where touch perception and processing within the primary somatosensory cortex ... -
Thigh-calf contact parameters for six high knee flexion postures: Onset, maximum angle, total force, contact area, and center of force.
(Elsevier, 2018-01-23)In high knee flexion, contact between the posterior thigh and calf is expected to decrease forces on tibiofemoral contact surfaces, therefore, thigh-calf contact needs to be thoroughly characterized to model its effect. ... -
Three-dimensional comparison of static and dynamic scapular motion tracking techniques
(Elsevier, 2014-02)The shoulder is complex and comprised of many moving parts. Accurately measuring shoulder rhythm is difficult. To classify shoulder rhythm and identify pathological movement, static measures have been the preferred method. ... -
TIME VARYING GENDER AND PASSIVE TISSUE RESPONSES TO PROLONGED DRIVING
(University of Waterloo, 2008-08-15)Background: Prolonged sitting in an automobile seat may alter the passive tissue stiffness of the lumbar spine differentially in males and females. Gender specific ergonomic interventions may be indicated for the ... -
Time-varying changes in the lumbar spine from exposure to sedentary tasks and their potential effects on injury mechanics and pain generation
(University of Waterloo, 2010-01-12)General body discomfort increases over time during prolonged sitting and it is typically accepted that no single posture can be comfortably maintained for long periods. Despite this knowledge, workplace exposure to prolonged ... -
Towards the establishment of a worker-centered framework to physically prepare firefighters: The evaluation of movement and the transfer of training
(University of Waterloo, 2013-01-23)Firefighter injuries are a billion dollar problem every year with an even larger human impact. Substantial efforts have been made to reduce the associated costs, yet many of the injuries sustained are the director result ... -
Towards the use of 2-dimensional video-based markerless motion capture to objectively evaluate kinematics during functional capacity evaluation
(University of Waterloo, 2020-10-26)Backgrounds Workability, the capacity to perform work, is a concept highly regarded in a return-to-work context and typically measured using functional capacity evaluation (FCE). The aim of FCE is to determine the capacity ... -
Trainability of Core Stiffness: Studies of Core Training Methods on Naive and Savvy Populations
(University of Waterloo, 2014-01-24)Core exercise is a staple of many physical training regimens with goals ranging from improving athletic performance to rehabilitation of spine and knee injuries. Traditionally, dynamic movements such as flexion, lateral ... -
Treadmill Walking Capacity among Older Adults in Assisted Living Settings: A pilot, feasibility study
(University of Waterloo, 2009-08-28)Background: Decreased physical activity levels are an increasing concern, specifically for the aging population. Older adults (>65 years) are able to achieve health benefits from participating in a regular exercise program ... -
Two weeks of docosahexaenoic acid (DHA) supplementation increases synthesis-secretion kinetics of n-3 polyunsaturated fatty acids compared to 8 weeks of DHA supplementation
(Elsevier, 2018-10)Docosahexaenoic acid (DHA, 22:6n-3) must be consumed in the diet or synthesized from n-3 polyunsaturated fatty acid (PUFA) precursors. However, the effect of dietary DHA on the metabolic pathway is not fully understood. ... -
