Re: any suggestion on recruiting muscle synergies using OpenSim API

Dear Thomas Thank you so much for your replying. I have read one of these papers. Also, I have seen the webinar related to another research you have mentioned. I have a question. Do you think is it possible to remove muscle excitations from control variables and define them dependent on muscle syner...

any suggestion on recruiting muscle synergies using OpenSim API

Hello I am trying to recruit muscle synergies in order to control a musculoskeletal model. My goal is to use muscle weights of synergies to reduce the number of control variables. For doing this, I want to define muscle excitations as dependent control variables on muscle synergies and their activat...

Ground contact modelling

Hello to everyone I am working on gait simulating of an amputee using prosthesis (Amputee with prosthesis model from https://simtk.org/projects/bkamputee_model ). In my simulation, I had previously done CMC and forward dynamics using available gait markers and GRF data on OpenSim directory (in GUI)....

Re: Failure for forward dynamics during gait simulation

Dear Xijin
Did you succeed in performing your simulation? if you did, i was wondering if you tell me how did you use reserve actuators or doing something which helped you

Re: using CMC through OpenSim API

Dear Jordan Thanks a lot for your replying.As it was really time-consuming process to find out what the problem exactly is, i passed this issue by using GUI and i faced to some other problems which is related to implementing forward scheme and integrating external actuator to gait model. if you thin...

Re: study the impact of exoskeleton on energy consumption Opensim

So, how Opensim can help us to simulate movement of people with some disabilities and weak muscles. I think after doing CMC and obtaining muscle excitation we must use excitation Editor and change a specific excitation which is a number between 0-1. after that, use this edited file to run Forward D...

amputee model using powered prosthesis forward dynamics simulation

Dear all viewers I am trying to perform simulation of a transtibial amputee using the powered prosthesis in opensim. I have edited a modified gait2354 model (using MATLAB scripting and XML file editing) which has been modified to simulate an amputee with passive prosthesis ( https://simtk.org/projec...

Re: using CMC through OpenSim API

Thank you very much for your answer.
What i inferred from your reply is that the problem with using CMC in opensim api is with its setup XML file which must be updated.
Am i right?

using CMC through OpenSim API

Hello to everybody. I am trying to control a prosthesis in MATLAB and to do this, i want to use reduced gait models of opensim. in this stage i got some problems with CMC. i use OpenSim API in MATLAB. despite the fact that information about CMC class is available on OpenSim API documentation, i coul...
