GaitNet OA Workshop: A Cross-Canada Osteoarthritis Gait Initiative
Chair: Dr. Cheryl Kozey

All are invited to this workshop which will provide a summary, update and panel discussion of a CIHR and Arthritis Society supported meeting of cross-Canada and international researchers and stakeholders focused on examining the role of biomechanics and neuromuscular control of gait in the pathogenesis and treatment of osteoarthritis. The original meeting took place in October 2017 in Halifax, and brought together 40 individuals, including researchers from 9 universities across Canada, clinicians, trainees, consumers, members of the Arthritis Society, industry partners and support staff. The presentations and discussions focused on answering identified priority questions related to translation of research knowledge in mobility and osteoarthritis and establishing standards for osteoarthritis gait research. This workshop will highlight successes and outcomes of the meeting, with a focus on discussion for next steps and future initiatives in multi-center biomechanics trials in Canada, and translational efforts for uptake of biomechanics knowledge.

Beyond Visual3D Workshop
Chair(s): Dr. Scott Selbie, Marcus Brown

Visual3D has been the backbone of our research and development efforts. With customers in more than 50 countries, with more than 1100 sites, and 7000 licensed activations, the evolution of Visual3D has been steady over the past 20 years, becoming somewhat of a standard in biomechanics analysis software. Skeletal pose estimation, the prime analytical engine in Visual3D, is arguably the core challenge for experimentally driven 3D biomechanical analyses of movement. The objective of this workshop is to present our research and development efforts to mitigate errors in pose estimation resulting from Soft Tissue Artifact (STA), and to highlight our efforts to work with data recording techniques that are less sensitive to STA.
With funding from the U.S. National institutes of Health (NIH), we developed a probabilistic pose estimation algorithm based on Bayesian inference, that provides a principled way to include models of STA in the Pose estimation algorithms and in initial testing produced better Pose estimates of the skeleton. The basis, and the gold standard comparison, for the STA models we tested was derived from another NIH funded project on Dynamic Stereo X-ray, which is is unaffected by STA and is the only currently available technology that can achieve sub-millimeter accuracy for a wide variety of functional movements. Lastly, we will present HASMotion’s 3D markerless motion capture based on Deep Convolutional Neural Networks.
