A Biomechanical and Neuromuscular Investigation of Femoroacetabular Impingement: Understanding Pathomechanics using Inclined and Declined Walking
(2020-08-26)Femoroacetabular impingement (FAI) is a proliferative musculoskeletal diagnosis in young adults. The purpose of the current study was to investigate the effect of challenged walking on gait mechanics in individuals with ... -
Changes in Knee Joint Muscle Activation Patterns during Walking Associated with Increased Structural Severity in Knee Osteoarthritis
(Elsevier, 2013)Purpose To determine whether alterations in knee joint muscle activation patterns during gait were related to structural severity determined by Kellgren–Lawrence (KL) radiographic grades, for those with a moderate knee ... -
CONTRA-LATERAL KNEE JOINT FUNCTION IN MODERATE KNEE OSTEOARTHRITIS: AN ELECTROMYOGRAPHIC INVESTIGATION OF KNEE MUSCLE CO-CONTRACTION
(2017-08-28)Unilateral knee osteoarthritis (OA) often progresses to bilateral disease, yet studies focused on joint function during walking often test the symptomatic knee only. The thesis objectives were: i) identify whether ... -
Data Science Strategies for Modelling Total Knee Arthroplasty Patient Variability
(2021-03-30)Knee osteoarthritis (OA) can present through self-reported patient symptoms and joint-level manifestations, impairing mobility and function. Symptom relief and functional restoration of end-stage OA is typically treated ... -
THE EFFECT OF HEALTHY AGING ON TRUNK NEUROMUSCULAR ACTIVATION PATTERNS DURING A CONTROLLED FUNCTIONAL TRANSFER TASK
(2013-04-08)Healthy aging is associated with an increased incidence of injuries such as low back pain and falling. Age-related changes in trunk neuromuscular activation patterns could potentially explain uncontrolled trunk motion, a ... -
The effect of knee joint effusion on gait mechanics and muscle activation characteristics in moderate knee osteoarthritis
(2018-08-29)Knee osteoarthritis (OA) is one of the most prevalent joint diseases, and knee effusion, as a manifestation of synovitis, is associated with knee OA clinical outcomes and disease progression. Thesis objectives were i) to ... -
Evaluation of DeepLabCut as a Human Markerless Motion Capture Tool
(2023-08-31)There are a variety of motion capture methods available; however, many of them are not well suited for collections outside a laboratory setting. AI markerless motion capture may fit this need, but its implementation and ... -
Fit Performance and Responsiveness of Ice Hockey Goaltender Leg Pads
(2022-08-31)Ice hockey goaltenders wear large leg pads that protect them and allow them to adopt common save positions like the butterfly. Leg pad models use different constructions to make pads stiff or flexible. The purpose of this ... -
Inter-Limb Asymmetry in Motion: Combining Clinical and Biomechanical Outcomes to Understand its Prevalence and Responsiveness in Knee Osteoarthritis
(2024-06-27)Walking is consistently recommended for individuals with knee osteoarthritis; however, many avoid physical activity due to pain. Individuals with knee osteoarthritis may attempt to alleviate this pain by adopting asymmetrical ... -
KNEE MECHANICS OF HEALTHY AND OSTEOARTHRITIC JOINTS
(2019-12-17)Objective: Knee Osteoarthritis (OA) can be the result of both mechanical and biological events that interfere with normal joint function. The aims of this thesis were to (1) quantify the biomechanical factors that ... -
Modeling the Patient Variability and Hierarchy in Joint-Level Kinematic and Kinetic Function Before and After Primary Total Knee Arthroplasty Surgery
(2017-04-05)The purpose of this study was to comprehensively capture the variability of improvement in knee joint-level biomechanics during walking gait of participants immediately before to one year after TKA, measured objectively ... -
Physical Activity and the Role of Walking in Knee Osteoarthritis
(2023-11-10)Walking is recommended as a type of physical activity for individuals with knee osteoarthritis, yet this population is physically inactive. The quantitative effects of walking exercise on joint health to inform walking ... -
Relationship between knee adduction moment patterns extracted using principal component analysis and discrete measures with different amplitude normalizations: Implications for knee osteoarthritis progression studies.
(Elsevier, 2015-12-30)BACKGROUND: Knee adduction moment discrete features (peaks and impulses) are commonly reported in knee osteoarthritis gait studies, but they do not necessarily capture loading patterns. Principal component analysis ... -
Reliability of Principal Components and Discrete Parameters of Knee Angle and Moment Gait Waveforms in Individuals with Moderate Knee Osteoarthritis
(Elsevier, 2013)Gait measures are used to evaluate change in patients with knee osteoarthritis (OA), but reliability has not been fully established in this population. This study examined test-retest reliability of knee angle and moment ... -
Standing Balance Control in Patients with Acromegaly
(2023-12-15)Patients with acromegaly (PWA) experience higher rates of falls and fall-related injuries than Canadian older adults. Therefore, the aim of the present study was to determine if acromegaly influenced the control of standing ... -
Three-Dimensional Kinematics of the Upper Limb During Four Functional Lifting Tasks
(2017-12-15)Kinematics is a branch of classical mechanics responsible for the description of the motion of an object, or series of objects, in space. This study uses 3-D motion capture to record the motion of the torso and upper ... -
TRUNK MUSCLE ACTIVATION PATTERNS ADAPT TO DEFICITS IN INDIVIDUAL SPINAL SYSTEMS
(2019-08-27)In the early 1990’s Panjabi proposed a theoretical model suggesting one risk of low back pain is a spinal instability event theorizing a deficit to any spinal system (active, passive and neural) could represent a risk. ... -
UNDERSTANDING SELF-REPORTED INSTABILITY USING GAIT OUTCOMES AND WALKWAY SURFACE TRANSLATIONS IN THOSE WITH KNEE OSTEOARTHRITIS
(2020-08-31)Knee osteoarthritis (OA) is a progressive disease that is highlighted by debilitating symptoms that have detrimental impacts on physical activity. One such symptom is knee instability, which is self-reported in 60-80% of ...
