The muscles operating closest to their functional limits produce the “weak link” for locomotor ability. This study shows that both young and old adults operate at a much greater relative effort at their ankle plantarflexor than knee extensor muscles during walking and running. This suggests that...
For most synovial joints, muscles provide the primary loading. Strong muscles that are working in balanced synergies are associated with joint health, while muscle weakness and muscle imbalance have been associated with joint degeneration often leading to osteoarthritis (OA). Furthermore, early OA h...
To our knowledge, this is the first mapping study investigating cutaneous thermal thresholds of the human torso. We found females to be more sensitive than males, and specific sensitive and insensitive locations, regardless of gender or the temperature protocol used.
This study found that sagittal plane trunk posture is associated with relative work contribution of hip and knee extensors during stance phase of running. Specifically, a more flexed trunk is related to less knee extensor work and greater hip extensor work contribution. The information may be utiliz...
Using a probabilistic modelling framework, we demonstrated that some combinations of varus-valgus component malalignments from the native joint lines during total knee arthroplasty caused elevated tibial forces and ligament tensions during both level walking and stair climbing. Thus, avoiding these ...
We investigated the influence of an American football helmet on axial loading at the cervical spine during low-velocity impacts at eight impact locations to a Hybrid III headform. Compared to bare head impacts, the football helmet condition frequently resulted in increased axial loads at the cervica...
We aimed to find a relationship between mechanical stiffness and hysteresis of equine SCB, and in vivo fatigue-induced microdamage. We found mechanical properties of cartilage-bone were associated with the damage volume of the specimens and were significantly different between specimens with and wit...
Biomechanical studies typically model the ankle as a rigid foot segment, and thus the contribution of structures within the foot to overall leg stiffness has been largely neglected. We designed a study to investigate the contributions of the ankle, midfoot and forefoot to lower limb stiffness. We hy...
Muscular hydrostats such as the tongue are modeled using the finite-element (FE) method, which is computationally expensive. To reduce the computational cost, approximate techniques based on dimensionality reduction (DR) and deep neural networks (DNN) have been proposed. On the one hand, linear DR t...
The purpose of this research was to validate wireless inertial sensor measures of hip joint orientation during dynamic tasks. Inertial sensor derived hip joint angles (found using acceleration, angular velocity, and magnetic field data) are compared to those found using a 3D camera-based laboratory ...
In this work, we developed 2D and 3D cell-based in vitro experimental models to visualize how cellular motions and stresses are correlated during aggregation and dissemination of cellular clusters. For quantitative analyses, we utilized particle image velocimetry (PIV), traction force microscopy (TF...
The relationship between trunk musculature endurance and running kinematics has been understudied. This study aimed to determine the influence of trunk endurance on sagittal plane joint ranges of motion (ROM) in male and female adolescent long-distance runners. Results suggest that greater trunk end...
Humans and chimpanzees walk quite differently, and it is unclear how posture and morphology influence the distinct gait patterns observed between species. We instructed humans to walk with various crouched postures to imitate the bipedal gait patterns of chimpanzees. While kinematics and ground reac...
Many investigations have been performed to understand the biomechanical relationship using biosignal. Surface EMG (sEMG) signal is particularly interesting part for human rehabilitation system in order to detect the gait intention and widely studied in the field of rehabilitation system. Intention d...
This paper presents a semi-active ankle prosthesis that adapts its stiffness to accommodate different gym exercises. The prosthesis is pneumatically actuated, and features a wireless adjustment of air pressure via smartphone app as well as a self-replenishing “pumping” mode, allowing operation w...
This abstract describes an automated, remotely deployable gait analysis technique that leverages machine learning and data from commercially available wearable sensors. The proposed technique is used to analyse gait in daily life for patients recovering from anterior cruciate ligament (ACL) reconstr...
