Development of a full flexion 3D musculoskeletal model of the knee considering intersegmental contact and deep muscle activity during high knee flexion
(University of Waterloo, 2019-01-24)Habitual kneeling in high knee flexion postures is a risk factor for knee joint dysfunction yet critical parameters for modeling this range of motion remain unknown or untested in three dimensions. High flexion is defined ... -
Development of a Wearable Sensor-Based Framework for the Classification and Quantification of High Knee Flexion Exposures in Childcare
(University of Waterloo, 2022-12-19)Repetitive cyclic and prolonged joint loading in high knee flexion postures has been associated with the progression of degenerative knee joint diseases and knee osteoarthritis (OA). Despite this association, high flexion ... -
Do East Asians Achieve Greater Knee Flexion than Caucasian North Americans, and are East Asian Kneeling and Squatting Styles Kinetically Different from North American Norms?
(University of Waterloo, 2016-01-20)High flexion postures (specifically, kneeling and squatting) are used with greater regularity in East Asian (Chinese, Japanese, Korean, and Vietnamese) cultures for many activities of daily living (ADL). Furthermore, the ... -
Effect of Club Selection and Clubhead Speed on the Knee Joint during the Golf Swing
(University of Waterloo, 2018-05-23)Golf is a sport that can be played throughout one’s lifetime providing an opportunity for competition, socialization, and improved physical activity. Golf is commonly recommended by physicians to those with knee ailments, ... -
Effect of Cyclic and Sustained Squatting Exposures on Hemodynamics and Subsequent Changes in Lower Limb Jumping Mechanics
(University of Waterloo, 2019-07-29)Occupational exposure to high knee flexion postures such as squatting or kneeling is associated with an increased risk of developing knee osteoarthritis. The exact mechanisms behind the increased risk are currently unknown. ... -
An Evaluation of Knee Joint Laxity, Mechanics and Muscle Activation Following Sustained Deep Flexion Kneeling
(University of Waterloo, 2016-01-22)Knee osteoarthritis (OA) is a complex disease with several proposed mechanisms for both the initiation and progression of the disease. Within the next 30 years, 1 in 4 Canadians are expected to have OA and 30% of the ... -
Gait Characteristics Change Following an Acute Exposure to Kneeling and Filtering Considerations for Gait Analysis
(University of Waterloo, 2023-02-03)Following sustained kneeling in young adults, kinetic and kinematic changes at the knee and ankle during gait have been observed (Gaudreault et al., 2013; Kajaks & Costigan., 2015a; Tennant et al., 2014). It is possible ... -
Investigation of a Double Calibration Technique to Reduce Soft Tissue Artifact Error in High Flexion
(University of Waterloo, 2022-02-01)High knee flexion tasks (knee flexion angle > 120 degrees) are performed frequently in both daily living activities (gardening, religious practice, exercise, etc.) and occupational settings (childcare, roofing, construction, ... -
An Investigation of Methods to Attenuate Soft Tissue Artifact of the Thigh in High Knee Flexion
(University of Waterloo, 2020-08-26)Soft tissue artifact during optical motion capture, or the movement of skin markers relative to bone, is widely accepted as a significant source of error in estimations of angles and moments. In some cases, the error ... -
Lower Limb Biomechanics in Walking, Running and Cycling: Implications for Overuse Injury
(University of Waterloo, 2019-09-27)A common anecdotal theory among endurance athletes is that cycling results in fewer knee injuries compared to running. This is thought to be due in part to a lower impact ground reaction force in cycling, compared to ... -
Neuromuscular Control of Gait and Squatting Following a Simulated Occupational Kneeling Exposure
(University of Waterloo, 2016-01-20)Frequent and prolonged occupational high knee flexion postures such as kneeling and squatting are associated with an increased risk for the initiation and development of knee osteoarthritis. In order to reduce the prevalence ... -
Passive Frontal Plane Knee Joint Laxity Following Anterior Cruciate Ligament Reconstruction Within 6 Months to 5 Years
(University of Waterloo, 2022-01-28)Following an anterior cruciate ligament rupture, surgical reconstructions aim to restore the joint stability. Increased frontal plane laxity has been observed in the anterior cruciate ligament deficient knee, intra-operatively ...
