OpenSim plugin to extract the muscle lines of action

Luca Modenese & Andrew T. M. Philips
MuscleForceDirection plugin for extracting the muscle lines of action updated to OpenSim 4.1. The plugin has been compiled using the API of OpenSim v4.1 and VS Community 2019 (v16.5.4).

Source Code and Force/Motion/Ultrasound Data to Validate an Instrumented Ultrasound System to Characterize Probe Force

Tyler Schimmoeller, Robb Colbrunn, Tara Nagle, Mark Lobosky, Erica Neumann, Tammy Owings, Benjamin Landis, Eric Jelovsek & Ahmet Erdemir
The provided software and data were used to demonstrate an instrumentation strategy for an ultrasound system to fully characterize the ultrasound probe force, orientation, and optionally its movement during imaging while efficiently synchronizing all data. A known method for compensation of the ultrasound probe weight was implemented, and a novel method for temporal synchronization was developed, which utilizes the electrocardiogram feature built in to the ultrasound. The system was used to perform anatomical imaging of...

The UPatras Eye Model – An OpenSim Oculomotor Model and Controller for Kinematics and Dynamics Simulations

Filip Konstantinos, Stanev Dimitar & Moustakas Konstantinos
The UPatras Eye Model files include the model, source code, documentation and controller plugin for use with OpenSim v3.3 x64. This model is based on the passive pulley hypothesis, constructed based on the data reported in literature regarding physiological measurements of the human eye. It incorporates an eye globe, orbital suspension tissues and six extraocular muscles. The excitation and activation patterns for a variety of targets can be calculated using the proposed closed-loop fixation controller...

Patrick Slade, Ayman Habib, Jennifer Hicks & Scott Delp
The Raspberry Pi image replicates the OpenSenseRT, a real-time and wearable system for motion capture.

ReadySim v1.0: A Computational Framework for Building Explicit Finite Element Musculoskeletal Simulations Directly from Motion Laboratory Data

Donald Hume & Kevin Shelburne
ReadySim aims to provide a means for researchers to perform musculoskeletal simulations directly in a finite element framework. Both the framework and the models are made open source to improve the dissemination of knowledge and drive continuous improvements to model design and modeling techniques. The software uses MATLAB and Python to interface with ABAQUS/Explicit input and output files and includes modules for model segment scaling, kinematics estimation, and muscle force optimization. The JobQueue API allows...
