[Opensim-announcement] Survey Results, ISB Events, and New OpenSim Resources

[Jennifer Hicks]

*NCSRR Support Survey Response Highlights*In April, we asked the community
to share information about grants and other funding applications that
benefitted in some way from OpenSim and NCSRR resources. We were excited to
learn that over 50 members of the OpenSim community have submitted more
than 120 applications to agencies including the NIH, NSF, DOD, CDC, VA, and
FDA. Nearly 70% of these applications were funded. Thank you to everyone
who replied to the survey and keep up the great research!

*OpenSim Workshop at TGCS 2017*
The OpenSim team at Stanford University is leading a workshop at the
ISB Technical
Group on Computer Simulation (TGCS)
<http://isbweb.org/~tgcs/iscsb-2017/index.html> on July 20, 2017 in The
Gold Coast, Australia. In this 3-hour workshop, the OpenSim team will use
hands-on tutorials to help participants learn how to use the Matlab
scripting interface with OpenSim 4.0. Learn more

about
the workshop.


*OpenSim 4.0 Tutorial at ISB 2017*The Stanford OpenSim team is also
organizing an interactive tutorial at the 26th Congress of the
International Society of Biomechanics (ISB)
<http://www.biomech2017.com/index.php> taking place July 23-27, 2017 in
Brisbane, Australia. The OpenSim team will lead hands-on examples on
building muscle-driven simulations and will present the key new features of
OpenSim 4.0. The teaching team includes Scott Delp, Jennifer Hicks, James
Dunne, Chris Dembia, Carmichael Ong, Jennifer Yong, and Apoorva
Rajagopal. Learn

about
the workshop.

*OpenSim Research Symposium at ISB 2017*
The third event in Australia this summer is a research symposium at ISB.
The symposium will highlight the latest research from leaders in the field
of musculoskeletal modeling and simulations, and close with a discussion
about the challenges and opportunities for using OpenSim in biomechanics
research. Speakers include Brian Umberger from the University of
Massachusetts, Colin Smith from the University of Wisconsin-Madison, Chris
Dembia from Stanford University, and Adrian Lai from Simon Fraser
University. We hope you’ll join us.

*New Matlab GUI Tool Optimizes Task Weights for RRA in OpenSim*
Michael Samaan of the University of California San Francisco and Old
Dominion University, along with his colleagues, developed and shared a
Matlab Graphical User Interface (GUI) tool that implements two different
numerical optimization algorithms that can be used to determine the optimal
task weights for use in the Residual Reduction Algorithm (RRA) in
OpenSim. Download
the tool here <https://simtk.org/projects/rra-opt-gui>. Two articles (Weinhandl
et al., 2013
<http://www.sciencedirect.com/science/article/pii/S0268003313001265>; Samaan
et al., 2016
<http://www.tandfonline.com/doi/full/10.1080/10255842.2016.1183123>)
related to this work have been published in the journals *Clinical
Biomechanics* and *Computer Methods in Biomechanics and Biomedical
Engineering*.

*Preparatory Co-Activation of the Ankle Muscles May Prevent Ankle Inversion
Injuries*
Matthew Demers and colleagues at Stanford University have published an
article <http://www.sciencedirect.com/science/article/pii/S0021929016311563>
that
uses OpenSim musculoskeletal simulations to evaluate muscle coordination
strategies that could potentially prevent ankle sprains. The researchers
generated simulations of landings on a 30 degree incline and showed that
co-activation of ankle evertor and invertor muscles just before ground
contact could prevent injury. In contrast, they found that stretch reflexes
were too slow and would therefore be ineffective for injury prevention. The
article appears in the February 2017 issue of the *Journal of Biomechanics*.
The model, data, and software tools are also available on the team’s Simtk
project page <https://simtk.org/projects/ankle-sprains/>.
