Quantification of spine stability: Assessing the role of muscles and their links to eigenvalues and stability
(University of Waterloo, 2011-12-21)Approximately 50% - 80% of the population will experience disabling low back pain at some point in their life. Assessing and developing interventions based on “lumbar stability” and/or joint stiffness to reduce low back ... -
Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations
(University of Waterloo, 2014-04-30)Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of ... -
Quantifying and predicting upper limb capability and dysfunction of breast cancer survivors
(University of Waterloo, 2014-12-15)Breast cancer will affect one in every nine Canadian women during their lifetime. As diagnostic and treatment methods improve, survival rates are approaching 90%. However, an alarming 30-82% of survivors suffer from ... -
Quantifying regional pectoralis major fatigue and its influence on performance of activities of daily living
(University of Waterloo, 2020-01-24)Extensive research reports on healthy shoulder function in the context of motion and muscular activity. However, less is known regarding how the shoulder complex and in particular its muscular components respond to ... -
Quantifying the Effects of Humeral Elevation Angle, Plane of Elevation, and Motion Phase on 3D Shoulder Kinematics during Dynamic Humeral Movement in Multiple Vertical Planes
(University of Waterloo, 2012-03-09)A thorough understanding of typical shoulder motion is desirable for both clinicians and shoulder researchers. With this knowledge, comparisons between normal and special populations (e.g. athletic, working, elderly, ... -
Quantifying the Shoulder Rhythm and Comparing Non-Invasive Methods of Scapular Tracking for Overhead and Axially Rotated Humeral Postures
(University of Waterloo, 2011-10-27)The present research quantified the shoulder rhythm for arm postures that represent the right-handed reachable workspace and compared 3 methods of scapular tracking: acromion marker cluster (AMC), stylus and scapular ... -
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 ... -
