Refining the relationship between the mechanical demands on the spine and injury mechanisms through improved estimates of load exposure and tissue tolerance
(University of Waterloo, 2008-07-09)The low back loading to which an individual is exposed has been linked to injury and the reporting of low back pain. Despite extensive research on the spine and workplace loading exposures, statistics indicate that efforts ... -
Relationship between the Magnitude and Location of Thigh-Calf Contact Force in High Flexion and Anthropometric Measures
(University of Waterloo, 2015-05-21)The soft-tissue contact between the thigh and calf during deep knee flexion results in tibiofemoral joint contact force reductions at angles beyond 134º of flexion (Caruntu et al., 2003; Zelle et al., 2009; Hirokawa et ... -
The relationships of prolonged standing induced low back pain development with lumbopelvic posture and movement patterns
(University of Waterloo, 2014-11-10)Over 80% of individuals will suffer from low back pain at least once in their lifetime. The cause within the population is not homogenous, leading to sub-classifications of non-specific low back pain. One such sub-classification ... -
Resolving the influence of work sequencing which includes overhead work: implications for job cycle designs
(University of Waterloo, 2013-01-25)Many industrial workplaces involve tasks that require work to be performed in overhead postures. Epidemiological evidence suggests that working in these unavoidable, awkward postures leads to development of shoulder fatigue, ... -
Risk Factors for Falls in Home Care and Long-Term Care Settings: A Focus on Dementia and Parkinson's Disease
(University of Waterloo, 2013-06-21)It is well established that there are many intrinsic and extrinsic risk factors associated with falls in older adults. Less well-known is what risk factors predict falls in more vulnerable populations, such as those with ... -
The Role of Apoptosis Repressor with Caspase Recruitment Domain in Aging Mouse Skeletal Muscle Morphology and Apoptotic Signaling
(University of Waterloo, 2015-01-23)Abstract Aging is associated with a loss of skeletal muscle mass, known as sarcopenia, which results in numerous degenerative alterations and decreased strength. One of the major mechanisms influencing muscle wasting in ... -
The Role of Binocular Vision during the Performance of Complex Manipulation Skills
(University of Waterloo, 2015-09-14)The overall goal for this thesis was to examine the significance of binocular vision during the performance of complex manipulation tasks in visually-normal children and adults. The goal of study 1 was to examine the ... -
THE ROLE OF CYTOSOLIC CALCIUM IN POTENTIATION OF MOUSE LUMBRICAL MUSCLE
(University of Waterloo, 2014-04-09)Following contractile activity, fast twitch skeletal muscle exhibits increases in submaximal force known as potentiation. Although there is no consensus on the purpose of potentiation, it is known to enhance power during ... -
The role of glutathione depletion in skeletal muscle apoptotic signalling in young and old rats
(University of Waterloo, 2010-09-27)There is substantial evidence that oxidative stress causes negative outcomes in many cell and tissue types. This is especially true of skeletal muscle, as it is continually subjected to various sources of reactive oxygen ... -
The Role of Heat Shock Protein 70 in Protecting Muscle Mechanical Function & SERCA Function in Human Skeletal Muscle
(University of Waterloo, 2009-04-23)Two studies were conducted to determine if Hsp70 is able to protect human skeletal muscle from muscle mechanical damage and alterations in SERCA activity associated with prolonged concentric exercise. In the first study, ... -
The role of phospholamban (PLN) in potential protection of sarc(endo)plasmic reticulum Ca2+-ATPase (SERCA) against oxidative stress
(University of Waterloo, 2015-01-23)Sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) sequesters Ca2+ from the cytosol to: i) aid in muscular relaxation and ii) refill SR Ca2+ stores for release upon subsequent stimulus for contraction. SERCA function is ... -
The Role of Sarcolipin in Calcium Handling and Obesity
(University of Waterloo, 2010-05-19)Sarcolipin (SLN), a small molecular weight, hydrophobic protein found in skeletal muscle, is a known regulator of sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) pumps. Earlier in vitro reconstitution experiments have ... -
ROLE OF SECOND MESSENGER SIGNALING PATHWAYS IN THE REGULATION OF SARCOPLASMIC RETICULUM CALCIUM-HANDLING PROPERTIES IN THE LEFT VENTRICLE AND SKELETAL MUSCLES OF DIFFERENT FIBRE TYPE COMPOSITION
(University of Waterloo, 2007-02-09)The overall objective of this thesis was to examine mechanisms involved in the acute regulation of sarcoplasmic reticulum (SR) Ca2+-handling properties by second messenger signaling pathways in skeletal and cardiac muscle. ... -
Role of visual information during stair locomotion
(University of Waterloo, 2011-03-30)Vision provides relevant information for safe locomotion in a variety of environments. During stair locomotion visual information may be important to detect step boundaries, transitions between ground level and stairs, ... -
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 ... -
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
