Segmented prosthesis

[Araceli Luque Martín-Sacristán]

Hello!

I am creating a model of a transtibial amputee with a running Specific prosthesis (blade prosthesis). I am modeling the prosthesis by 4 segments and I want to connect them in OpenSim with pinJoint with a torsional spring. How could I create a torsional spring and specify the stiffness of the joint? Or, is it another easier guay to do it?

You could try using a SpringGeneralizedForce at the coordinate of the PinJoint. Details of the class can be found at https://simtk.org/api_docs/opensim/api_ ... ml#details, and check out the XML Broswer in the GUI (Help --> XML Browser) to see the related XML tags for more information.
