Understanding Personal Determinants of Lifting Strategy to Inform Movement-Focused Ergonomic Interventions
(University of Waterloo, 2023-04-26)Introduction: Lift training interventions are needed to reduce risk in jobs with non-modifiable demands, but to date have been generally ineffective. The lack of lift training effectiveness has been partially attributed ... -
Understanding the determinants of independent mobility in older adults
(University of Waterloo, 2014-01-24)As aging occurs, safely maintaining an active lifestyle is critical for health and independence. Independent mobility is influenced by one’s ability to perform three essential tasks of daily living: transitioning from a ... -
Understanding the effect of objective function weightings on posture prediction: application to predicting lifting postures in un-fatigued and fatigued states
(University of Waterloo, 2021-04-28)Physical prototyping is often required when developing new equipment and workspaces so that human-systems integration can be considered. Digital human modelling facilitates more efficient, upstream assessment of human ... -
Understanding the Influence of Fear of Falling on Clinical Balance Control - Efforts in Fall Prediction and Prevention
(University of Waterloo, 2011-06-21)Introduction: A review of the literature shows that standard clinical balance measures do not adequately predict fall risk in community-dwelling older individuals. There is significant evidence demonstrating the interactions ... -
Upper extremity kinematic changes and shoulder muscle fatigue during a repetitive goal directed task
(University of Waterloo, 2017-01-20)Repetitive workplace tasks are associated with fatigue induced changes to shoulder muscular behavior, which can alter glenohumeral joint kinematics and lead to chronic injury. However, accessible and reliable methods to ... -
Use of a probabilistic model to explore the hip fracture and health economic outcomes of safety flooring implemented in an Ontario retirement home environment
(University of Waterloo, 2023-12-21)Hip fractures suffered by older adults are a serious public health concern. The direct yearly expenditure for hip fractures exceeds one billion dollars in Canada and with the older adult population expected to increase ... -
The Use of Shear Wave Elastography to Estimate the Mechanical Properties of the Soft Tissues Surrounding the Proximal Femur
(University of Waterloo, 2023-08-28)Introduction: Falls are the leading cause of injury, morbidity, and mortality amongst older adults nationally and worldwide, with 95% resulting in hip fractures. Previous studies have found that the soft tissues (subcutaneous ... -
Using a collaborative research approach to develop an interdisciplinary research agenda for the study of mobile health interventions for older adults.
(JMIR Mhealth Uhealth., 2015-02-10)Background: Seniors with chronic diseases are often called on to self-manage their conditions. Mobile health (mHealth) tools may be a useful strategy to help seniors access health information at the point of decision-making, ... -
Using an interactive website to disseminate participatory ergonomics research findings: an exploratory study
(University of Waterloo, 2007-09-21)Introduction: Researchers traditionally present the results of their research in academic journals and through conference presentations. Typically, individuals working outside of academia do not have access to traditional ... -
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 ... -
Variation of Force Amplitude and its Effects on Muscle Fatigue
(University of Waterloo, 2011-01-20)Current trends in industry are leaning towards specialized production systems and sedentary computer work tasks that are associated with low and less varying mechanical exposures. It has been suggested that physical ... -
Vascular Aging: Influences on cerebral blood flow and executive function
(University of Waterloo, 2007-09-17)An age-related decline in cerebral blood flow (CBF) is widely acknowledged. However, uncertainty exists as to whether this reduction is the result of a reduced metabolic demand (cerebral atrophy) or an impaired delivery ... -
Visual determinants of postural control and perception during physical and visual motion
(University of Waterloo, 2023-01-30)The control of balance and posture is a critical task of daily life to limit the risk of falls and potential injury. In order to be successful in the control of balance the central nervous system utilizes sensory feedback ... -
Visual Inputs and Motor Outputs as Indivduals Walk Through Dynamically Changing Environments
(University of Waterloo, 2006-12-01)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ... -
VISUAL INPUTS AND MOTOR OUTPUTS AS INDIVIDUALS WALK THROUGH DYNAMICALLY CHANGING ENVIRONMENTS
(University of Waterloo, 2006)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ... -
Vitamin B12 Deficiency in Older Adults Living in Ontario Long-Term Care Homes: Protocols, Testing Procedures and Prevalence
(University of Waterloo, 2015-09-24)BACKGROUND: Vitamin B12 status is a relevant topic to older adults and deficiency has avoidable clinical ramifications. While classical symptoms of B12 deficiency are either hematologic or neurologic, presentation of these ... -
Vitamin D, Parathyroid Hormone and Bone Quality in Persons with Chronic Spinal Cord Injury
(University of Waterloo, 2010-12-14)Background: Following spinal cord injury (SCI) declines in sub-lesional bone mineral density (BMD) occur, and are associated with a high prevalence of fractures. Conventional risk factors for osteoporosis diagnosis in the ... -
Wearable Hip Protectors: Validation of a Novel Test System and Evaluation Utilizing Pressure Sensing Methods
