Breast cancer survivor functional changes immediately following treatment: quantifying mechanisms of strength deficits and compensatory kinematic and muscular strategy adaptations
(University of Waterloo, 2021-11-04)Breast cancer is prevalent among Canadian women, but treatments may cause functional impairments among survivors. Over 22,000 Canadian women join the survivor population yearly (Brenner et al., 2020). Despite this substantial ... -
Comparing occupational musculoskeletal exposures during common materials handling tasks between non-obese and obese adults
(University of Waterloo, 2017-12-08)Higher body mass is associated with increased risk of musculoskeletal injury, a greater number of insurance claims, and higher direct and indirect costs due to decreased productivity during manual materials handling. Over ... -
Defining Normative Upper Limb Kinematics during Functional Capacity Evaluation (FCE) Task Performance
(University of Waterloo, 2015-08-24)The Functional Capacity Evaluation (FCE) is an evaluation tool used in the return to work process to guide treatment and decision making. An FCE involves testing the functional abilities of an individual to determine their ... -
Detecting subject-specific fatigue related changes in lifting kinematics using a machine learning approach
(University of Waterloo, 2021-01-07)Background. Functional capacity evaluations (FCEs) are used to determine a worker’s capacity for return to work (RTW) or for job matching purposes. FCEs are completed using a subjective approach, where a trained evaluator ... -
Evaluating Cervical Spine Response and Potential for Injury During Head-First Impact Loading Using a Finite Element Head-Neck Model
(University of Waterloo, 2022-02-04)Head-first impact (HFI) is caused by events such as rollover motor-vehicle accidents, falls, and sports, and can impose serious and detrimental hard and soft tissue injuries on the cervical spine. HFI is a loading condition ... -
Head and Neck Response of an Active 2 Human Body Model and Finite Element 3 Anthropometric Test Device During a 4 Linear Impactor Helmet Test
(American Society of Mechanical Engineers, 2020-02-01)It has been proposed that neck muscle activation may play a role in head response resulting from impacts in American Football. The importance of neck stiffness and active musculature in the standard Linear Impactor Helmet ... -
Human motion estimation and controller learning
(University of Waterloo, 2021-07-22)Humans are capable of complex manipulation and locomotion tasks. They are able to achieve energy-efficient gait, reject disturbances, handle changing loads, and adapt to environmental constraints. Using inspiration from ... -
The influence of body mass on posture, pressure distribution and discomfort during prolonged driving.
(University of Waterloo, 2007-09-27)Background: Currently, if traveling the posted speed limit, the typical commuter driver in the Toronto Metropolitan area will travel round trip upwards of 60 minutes a day to work (Heisz and LaRochelle-Cote, 2005). As ... -
Investigating the Association Between Enhancements in Perceptual Sensitivity to Object Form and Reach to Grasp Performance
(University of Waterloo, 2017-12-11)The act of reaching to grasp an object serves as a primary method of interaction with the surrounding environment. Therefore, it is important to understand the association between perceptual sensitivity to object form and ... -
Load-sharing and kinematics of the human cervical spine under multi-axial transverse shear loading: combined experimental and computational investigation
(National Library of Medicine, 2021-06)The cervical spine experiences shear forces during everyday activities and injurious events yet there is a paucity of biomechanical data characterizing the cervical spine under shear loading. This study aimed to 1) ... -
Lumbar Spine and Hip Kinematics and Muscle Activation Patterns during Coitus: A comparison of common coital positions
(University of Waterloo, 2013-01-31)Qualitative studies investigating the sexual activity of people with low back pain found a substantial reduction in the frequency of coitus and have shown that pain during coitus due to mechanical factors (i.e., movements ... -
Multi-scale modeling of head kinematics and brain tissue response to blast exposure
(Springer, 2019-09-15)Injuries resulting from blast exposure have been increasingly prevalent in recent conflicts, with a particular focus on the risk of head injury. In the current study, a multibody model (GEBOD) was used to investigate the ... -
Normative kinematics of reaching and dexterity tasks: moving towards a quantitative baseline for Functional Capacity Evaluations(FCEs)
(Taylor and Francis, 2017-12-15)Purpose: This work generates a comprehensive description of upper extremity and torso kinematics of a healthy population during reaching and dexterity Functional Capacity Evaluation (FCE) tasks. Methods: Upper limb and ... -
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, ... -
Variable-Structure Cable-Driven Parallel Robots
(University of Waterloo, 2022-05-16)Cable-driven parallel robots (CDPR) are a special class of robotic manipulators consisting of a rigid end effector suspended, constrained, and actuated by a number of length-varying cables. Since cable mass is typically ...
