The Influence of the Tensile Material Properties of Single Annulus Fibrosus Lamellae and the Interlamellar Matrix Strength on Disc Herniation and Progression
(University of Waterloo, 2009-07-30)
Low back pain is highly prevalent in the developed world, with 80% of the population being affected at some point in their lives. Herniation, a common injury to the intervertebral disc, is characterized as the posterior ...
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 ...
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 ...
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 ...
Age-related changes in the control of mediolateral dynamic stability during volitional and reactive stepping
(University of Waterloo, 2012-04-23)
The high incidence of falls and fall-related injuries among Canadians over the age of 65 continues to be a key public health issue. As the current proportion of individuals within this cohort of the population is predicted ...
Exploring interactions between force, repetition and posture on low back joint loading and intervertebral disc injury
(University of Waterloo, 2014-08-26)
Low back pain (LBP) affects approximately 80% of the population at some point in their lives, with 65% of cases becoming chronic pain sufferers. Approximately 40% of LBP cases are attributed to intervertebral disc (IVD) ...
Firefighter fitness, movement qualities, occupational low-back loading demands and injury potential
(University of Waterloo, 2012-02-21)
BACKGROUND and OBJECTIVES:
Low-back overexertion injuries represent a large proportion of fireground “strains, sprains and muscular pains” and are a leading cause of disability and early retirement in firefighters. Given ...
An investigation of the biomechanical factors influencing knee joint function following total knee replacement
(University of Waterloo, 2009-12-22)
Knee replacement surgery is often performed in cases where the pain due to knee osteoarthritis can no longer be effectively controlled by conservative measures. The surgery—which replaces the articular surfaces of the ...
