Complex computational shoulder models have been used to investigate and understand the biomechanics of Reverse Shoulder Arthroplasty(RSA), but despite the advancements in knowledge, impingement and limited ROM still remain a concern. To solve the problem, new technologies were introduced (e.g. Patie...

Purnima Padmanabhan and Dr. Ryan Roemmich research interests include the control of gait in persons with neurological disorders and the design of gait rehabilitation strategies. Here they will discuss their recent and exciting findings that leverage energy optimization to enhance gait retraining for...

Most running injury studies have used either purely biomechanical or purely epidemiological methods. Results from biomechanical studies comprise stepwise kinematic and/or kinetic variables,e.g. joint angles and/or moments, while results from epidemiological studies comprise training variables (e.g. ...

Imaging-based approaches for quantifying joint kinematics and arthrokinematics of joint movement have become more commonplace in the research environment. Both static and dynamic approaches are being utilized to quantify rotation and translation of the shoulder joint complex in global and anatomical...

Partial power assistance is a promising approach to reduce the deleterious upper extremity loads in manual wheelchair locomotion. This study investigates two potential control strategies to govern the wheelchair-user interaction: i) an impedance control strategy, where a reference, desired system dy...

We have previously reported that intrinsic foot muscle activation increases when running in cushioned running shoes, compared to barefoot running. A potential explanation for this finding is that the central nervous system increases muscle activation, altering foot stiffness to accommodate the added...

Wearable devices enables us to monitor human walking in the field. There is however technical trade off exists between the data richness and the wearable convenience. To extract motion information from the limited measurement data, we propose to exploit the biomechanical characteristics of human gai...

A set of hot-topics will be presented and will serve to stimulate the discussion with the audience. The aim is to agree on a limited number of important innovations for the development and exploitation of shoulder biomechanics.

Dr. Srinivasan studies energy optimization by combining human subject experiments, with simple mathematical models, and large-scale optimizations. Here he will discuss his recent work that finds that energy optimization explains a surprisingly large fraction of our locomotor repertoire.

The overall goal of this project is to use computer simulation tools to simulate the impact of radiation therapy (RT) treatment for oropharyngeal cancer. We further describe the advantages and challenges of investigating radiation impact using computer simulation.

When asked to be part of this symposium, I was reminded of the feeling I had when receiving my career award from the Canadian Society for Biomechanics – I felt I had made some significant contributions, but still had so many questions and ideas remaining that my career was at best half completed. ...

Carpal tunnel syndrome is caused by compression of the median nerve in the carpal tunnel. Division of the transverse carpal ligament is a routine surgical procedure to treat the hand problem. We have developed alternative biomechanical approaches to carpal arch space augmentation by radioulnar wrist...

Tendon exhibits a hierarchical fibrillar structure, and force transfer across tendon subunits and at different length scales is an integral part of the tissue’s mechanical function. Understanding multiscale mechanisms across distinct tendons may improve therapies to restore degenerate tendon ...

This study employed a novel, micro-grooved finite element model to characterize the contact mechanics at the total hip head-neck modular taper junction during implant assembly under different conical angles and head taper surface topography. Modeling the head taper as an idealized “flat” surface...

This study reports on a large investigation to explore the advantages of customisation in total ankle replacement (TAR). Potentially, this can minimise the critical prosthesis-to-bone mismatch, improve the accuracy of the implantation and also facilitate osseointegration. A general customisation pro...

Axons hyperpolarise when they transmit trains of action potentials. Presently, we explored the link between the hyperpolarisation of motor axons and contraction fatigability during functional electrical stimulation (FES). We found that axonal excitability decreased, and contraction fatigability incr...

Studies have identified that energetic costs of endurance running are similar between the sexes, but less is currently known about economical running biomechanics in female runners than male runners. Evidence shows that female runners have the ability to fine-tune their running mechanics to reduce m...

The process of aging has been shown to induce significant changes to the connective tissue structures associated with skeletal muscle. A commonly observed consequence of these changes is a reduction in muscle quality such that a relatively larger proportion of a muscle’s cross-sectional area is co...

Metabolic cost of transport (MCoT) of gait was estimated from marker data and ground reaction forces (GRFs). Sagittal plane joint angles and joint moments were determined using inverse kinematics and dynamics, respectively, and muscle states were determined by dynamic optimization. Metabolic cost of...

Wearable devices have enormous potential to enhance human performance and health if the devices are evidence-based and developed to meet a true need. An essential ingredient in developing these novel concepts has been biomechanists working in close collaboration with colleagues in materials science ...

Flapping flight is the most power-demanding mode of locomotion, associated with a suite of anatomical specializations in adult birds. In contrast, many developing birds use their forelimbs long before acquiring "flight adaptations", to enhance leg performance and, in some cases, fly. How does anatom...

The combination of model-based tracking techniques with biplane fluoroscopy for quantifying in vivo kinematics of various joints has evolved from initial, novel experimental applications, to more recent applications using clinical biplane fluoroscopy systems. The equipment and expertise needed to pe...

The force-length relationship in skeletal muscle is attributed to the requirement for overlap between the contractile proteins actin and myosin. However, this relationship shifts with changes in muscle activation. Here we present data suggesting that this activation-dependent shift occurs not only b...

Dr. Wong applies computational models and human experiments to questions across the realms of sensorimotor control, from reaching to energy optimization in locomotion.

Wearable sensing provides new, quantitative metrics to monitor recovery and rehabilitation after neurologic injury. Measurements from electromyography (EMG) sensors and inertial measurement units (IMUs) can be used for tracking muscle activity and movement to evaluate prognosis and progression. Meas...

A hallmark of human movement is its variability, reflected in normal fluctuations in motor performance that occur across multiple repetitions of a task (e.g. stride-to-stride, pedal cycle-to-pedal cycle). To better understand how skeletal muscles are recruited for different movement tasks it is ther...
