Hello.
I am researching about influence of foot prosthetic aligment on transtibial gait and i have a question. I saw this article
http://europepmc.org/articles/pmc3707817 about influence of foot prosthetic stiffness on transtibial gait and i would like know if this aproach (figure 1) is reproducible in Opensim? I want to run a entire transtibial gait cylcle and change prosthetic foot aligment each run. I thougt article aproach is similar to CMC tool but I am not sure because CMC needs GRF data and article aproach uses a foot contact model to replace GRF data. Also, I want to know if it is a good aproach or what is the best way to do it?
Figure 1
Thank you a lot for you attention

Yes
CMC tool but I am not sure because CMC needs GRF data
No, it doesn't require GRF to run-- if you want resonable muscle estimates from CMC you should account for the forces on the model, and in walking that would mean including the GRF's.

That depends on your research question and your access to the tools you have at your disposal. I would suggest doing a literature review.

Ok, I get it. The main issue is at this moment i dont have GRF data. For this reason I was wondering if there is any problem using CMC tool with foot contact model (figure 1), in this case hunt-crossley model.

My research question: If i modify foot aligment parameters, what will be the kinetic and kinematic consequences on transtibial gait?
After long literature review i found that i could use dynamic optimization framework to answer research question. I think CMC is similar like that but i was not sure about it.
Thank you once again.
