Development and Application of a Probabilistic/Mechanistic Model to Investigate the Influence of Safety Flooring on Population-Level Hip Fracture Risk
(University of Waterloo, 2017-08-28)
Hip fractures are a devastating injury in the older adult population. They are almost exclusively sustained during a fall-related event, with lateral falls resulting in an impact to the proximal femur most highly associated ...
The Effects of Varying Surface Translation Acceleration and Velocity on Compensatory Forward Stepping Responses
(University of Waterloo, 2018-11-16)
Introduction: Examination of balance control has often been accomplished via evocation of stepping responses through external perturbations. These external perturbations can take the form of sudden underfoot surface ...
Regional activation of anterior and posterior supraspinatus differs by plane of elevation, hand load and elevation angle
(Elsevier, 2018-12-01)
The supraspinatus is one of the muscles of the rotator cuff, and growing research on fibre type composition and mechanical advantages in specific postures suggest this muscle may have distinct anterior and posterior regions. ...
The effects of a simulated occupational kneeling exposure on squat mechanics and knee joint load during gait
(Taylor and Francis, 2017-12-01)
Occupational kneeling is associated with an increased risk for tibiofemoral knee osteoarthritis. Forces on the knee in the kneeling posture, as well as the greater incidence of meniscus tears among workers, likely contribute ...
Biomechanics of Lateral Hip Impacts: the Influence of Measurement Technique and Contact Area
(University of Waterloo, 2014-02-21)
The experiments presented in this thesis provide novel insight into two scarcely studied areas in the field of lateral hip impact biomechanics. The high energy nature of hip impacts requires high sampling rates for accurate ...
A biomechanical investigation into the link between simulated job static strength and psychophysical strength: Do they share a “weakest link” relationship?
(University of Waterloo, 2011-01-17)
Maximum voluntary forces and psychophysically acceptable forces are often used to set force guidelines for exertions as a means to protect against overexertion injuries in the workplace. The focus of this dissertation was ...
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% ...
New Insights into the Landing Phase of Reactive Stepping: Predictors of Control, Muscle Recruitment, Movement Restraints and Two-Step Responses
(University of Waterloo, 2017-09-27)
Preventing falls and fall-related injuries are public health challenges of the upmost importance for Canadians, particularly for older adults. Due to the severe consequences that can accompany a fall (e.g., traumatic brain ...
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 ...
Using pattern recognition to detect differences in movement strategy between high and low relative biomechanical exposure lifts and lifters: Application to backboard lifting
(University of Waterloo, 2018-12-13)
Introduction:
Backboard lifting is a demanding aspect of paramedic work that results in higher low back moments and sagittal trunk angles compared to other paramedic tasks. Movement strategy in a backboard lift affects ...
