OpenSim+ Advanced User Workshop at Stanford University
March 11-13, 2024
Application Deadline: December 15, 2023
The Wu
Tsai Human Performance Alliance, Restore
Center, and Mobilize
Center are now accepting applications for a three-day, project-based
workshop on the Stanford University campus. This workshop is intended for researchers who are advanced users of our software tools, including OpenSim, OpenSim
Moco, OpenSense, Sit2Stand,
and OpenCap.
Advanced users include those who are applying these tools to new use cases or developing new pipelines, models, or algorithms. Researchers will work with our staff to advance the goals of their specific research projects. We highly encourage collaborators
to participate in the workshop as a team.
New Simulation Approach Predicts Human-Tech Interaction with Assistive Devices
Exotendon assistive devices have been shown to reduce the rate of energy expenditure during running. Jon Stingel and a team of Mobilize
Center researchers at Stanford University wanted to better understand the muscle-level changes that contributed
to these cost savings. The team created a musculoskeletal simulation framework that revealed the cost savings came from the quadriceps, hamstrings, and several muscles that control the hip. This framework could be used to study human-device interactions more
generally and aid the design process.
Quantify and Analyze Human Movement using Two Smartphones with OpenCap Software
Drs. Scott Uhlrich, Antoine Falisse, and Lukasz Kidzinski, along with other Mobilize
Center researchers at Stanford, have developed OpenCap, a freely available, cloud-based tool that uses
two smartphones to measure both human movement kinematics (i.e., joint angles) and kinetics (e.g., muscle activations, ground reaction forces, and joint loading). OpenCap enables researchers to capture human movement 25% faster at a fraction of the cost. The
validation of the software is described in a publication that appeared recently in PLOS Computational Biology.

Participate in the NMSM Pipeline Stroke Grand Challenge
We encourage you to learn about and participate in the first Stroke
Grand Challenge Competition using the MATLAB-based Neuromusculoskeletal
Modeling (NMSM) Pipeline built on top of OpenSim. Organized by the Rice
Computational Neuromechanics Lab and held at the American Society of Biomechanics annual conference, the competition will provide the biomechanics research community with one comprehensive
post-stroke walking dataset each year to design a personalized stroke neurorehabilitation treatment using the NMSM Pipeline or any other software. Winners of the competition will receive a certificate, $1,000 cash prize, and fast-tracked review in the Journal
of NeuroEngineering and Rehabilitation.

Novel Spine Model Validated for Dynamic Lifting Tasks
Mohammad Akhavanfar, Thomas Uchida, and colleagues at the University of Ottawa have developed a novel model for calculating spinal forces during dynamic lifting tasks. The Fully
Articulated Thoracolumbar Spine (FATLS) model includes thoracic and lumbar segments and accounts for the
effect of passive moments. Previously validated for various static lifting tasks, this latest study expanded the validation to nine dynamic lifting tasks. The authors recommend using their model for estimating intervertebral spinal forces during lifting and
lowering tasks.
