Radiographic Examination of Humeral Head Migration after Fatiguing the Rotator Cuff
(University of Waterloo, 2010-01-04)Undesirable work factors, such as awkward upper body postures and repetitive arm motion, in the workplace can lead to upper extremity pain. Research suggests that these work-related factors, and subsequent rotator cuff ... -
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 ... -
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. ... -
Regional activation of supraspinatus and infraspinatus sub-regions during dynamic tasks performed with free weights
(Elsevier, 2022-02)Growing evidence supports the existence of distinct anatomical sub-regions within supraspinatus and infraspinatus, but only recently has attention turned to exploring their potential functional differences. Using indwelling ... -
Regional Cerebral Blood Flow Differences Between the Middle Cerebral Artery and the Basilar Artery
(University of Waterloo, 2017-09-27)Much of the research that has investigated cerebral circulation has used the MCA and has assumed that it is an indicator of what is happening in all regions of the brain. Yet little research exists to validate this notion. ... -
Relational Mealtimes in Long-Term Care: Understanding the context of care at mealtimes for residents with eating and other mealtime challenges
(University of Waterloo, 2021-09-21)Background: Mealtimes in long-term care (LTC) are essential to resident health and well-being, as eating with others helps to reinforce relationships between those who live and work in these homes and their relationships ... -
The Relationship Between Heart Rate and Self-reported Sickness in Commercially Available Virtual Reality Environments
(University of Waterloo, 2020-05-13)Virtual reality (VR), while beneficial in research, training, and entertainment has the tendency of causing cybersickness (CS). The symptoms range from mild to severe depending on the individual. There exists a gap in the ... -
The Relationship Between Muscle Capacity Utilization During Gait and Pain in People With Symptomatic Knee Osteoarthritis
(University of Waterloo, 2020-09-29)Muscle capacity refers to an individual’s ability to utilize their muscle strength and power in order to efficiently and effectively complete physical activities (Brady & Straight, 2014). Muscle capacity is associated ... -
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 ... -
Representing fine-wire EMG with surface EMG in three thigh muscles during high knee flexion movements
(Elsevier, 2018-12-01)Activation waveforms of vastus intermedius, adductor magnus, and semimembranosus have not been reported for high knee flexion activities such as kneeling or squatting, likely due to the invasive procedures required for ... -
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 Assessment and Interventions for Individuals at Risk of Osteoporotic Fractures
(University of Waterloo, 2022-08-30)Older adults, especially with low bone mass, hyperkyphosis or vertebral fractures (OVF), and individual with spinal cord injury (SCI) are at increased risk of fragility fractures. Individuals with SCI and OVFs are subgroups ... -
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 Activities of Daily Living in Healthy Vascular Aging
(University of Waterloo, 2022-01-05)Normal aging leads to endothelial dysfunction and arterial stiffening implicated in cognitive decline. Cerebral blood flow also declines with aging. Elevated blood flow during exercise produces laminar shear stress which ... -
The Role of Acute High-Intensity Interval Exercise as a Potential Facilitator for Improved Executive Functions and Affect in Healthy Young and Older Adults
(University of Waterloo, 2021-01-06)A single bout of aerobic exercise has been shown to improve executive functions and affect across the lifespan. The magnitude of improvements appear to be influenced by exercise-dependent factors, including the intensity ... -
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 ... -
