Agenda

Part 1: Basic Course - Data processing
We will introduce OpenSim and demonstrate a typical data processing workflow in OpenSim (using the GUI) with a hands on example. To complete the hands on exercise, bring a laptop with OpenSim 3.3 installed. Software can be found at http://opensim.stanford.edu/.

09.00-10.45     Introduction to OpenSim’s models and tools

Analysis of drop landing based on experimental data
using the OpenSim GUI (scaling, inverse kinematics, inverse dynamics, static optimization)

11.15-13.00     Joint contact forces during drop landing
using the OpenSim GUI (analyze) and plugin (to generate FE modeling input)

Part 2: Advanced Course – Muscle-driven simulations and optimal design
We will demonstrate how OpenSim can be used to generate forward simulations of motion and for simulation-based design of assistive devices with a hands on example using both the GUI and the API. To complete the hands on exercise, bring a laptop with OpenSim 3.3 and matlab installed. Software and instructions for setting up the OpenSim-matlab interface can be found at http://opensim.stanford.edu/.

14.30-16.15     Evaluate ankle inversion injury risk in a drop landing

using forward simulations in the OpenSim GUI

16.45-18.30     Simulation-based design of orthosis to prevent injuries
using the OpenSim-Matlab interface

General information

The GAMMA (Gesellschaft für die Analyse Menschlicher Motorik in ihrer klinischen Anwendung, http://www.g-a-m-m-a.org) society focus on the clinical applications of 3D gait analysis. During this workshop the participants will learn how to use the OpenSim GUI for a typical data processing workflow. This workshop follows a similar workflow and uses the same example data as a previous OpenSim workshop (ESB 2017).

Preparing for the workshop

Participants should bring a laptop with OpenSim 4.0 installed or be prepared to team up with other participants. OpenSim model files and setup files are written in xml. Notepad++ is a free text editor that makes it easier to view and edit xml files.  During the workshop we will use Notepad++ to examine OpenSim files. Hence, please download and install following software prior to the workshop.

• OpenSim 4.0 (https://simtk.org/frs/?group_id=91)
• Notepad++ (https://notepad-plus-plus.org/downloads/v7.8/)

Agenda

Each point on the agenda will start with a short introduction talk from the organizers (5 to 10 minutes). Afterwards the participants can try to do each step on their laptop for approximately 20 minutes. The organizers will support the participants during the hands-on sessions.
To complete the tutorial please download data and setup files. For your reference, we also provide the the output files.

Additional geometry files.

Joint contact forces during drop landing

Evaluate ankle inversion injury risk in a drop landing

For this part of the workshop, we refer you to the online tutorial material provided by the OpenSim developers.

If you want to participate in the design competition - part I, send your optimal trajectory of the subtalar angle along with your design choices and a brief motivation about why you consider them to be optimal to ilse.jonkers@kuleuven.be, who will act as the jury.

Simulation-based design of orthosis to prevent injuries

To complete the tutorial, download the example scripts.

If you want to participate in the design competition - part II, send your optimal trajectory of the subtalar angle along with your design choices and a brief motivation about why you consider them to be optimal to ilse.jonkers@kuleuven.be, who will act as the juryPlease copy this folder to your 'data and setup files' folder.
