Hi :-) Does anybody know if there is the possibility to plot the length of a ligament after a motor task?

Thank you very much

Hi Caterina,

I'm not sure how to plot ligament object lengths exactly, but if the ligament length is not showing up as a plotting choice, you could create a new muscle model that has the same coordinates as the ligament, and zero out its active and passive force properties. Then you can plot it as you would any muscle length in the Plotter tool.

I used to do this in old SIMM when trying to model the IT band, I think it will work in OpenSim too.

Good luck,
Ross

Hi Ross, thank you very much! I think that at the moment it is the best-only solution thanks for the suggestion! ;)
