There are a lot of details to carefully consider when working with EMG. The Verification and Validation paper for OpenSim ( Is My Model Good Enough? Best Practices for Verification and Validation of Musculoskeletal Models and Simulations of Movement ) discusses ...

Hello, I am working with IMU and EMG and I try to convert .c3d files in suitable files for OpenSim by using Matlab r2022a. When I run "configureOpenSim", ...

How can I compare Activation to EMG or can I convert Activation to EMG? Even after rectifying, filtering, and normalizing, EMG will still differ from ...

How can I compare Activation to EMG or can I convert Activation to EMG?

Thank you

Hi, OpenSim does not convert EMG to activations, but the process is straightforward. Please see the previous posts for relative answers ...

... during some walking experiment. we dont have any force plates or EMG sensors and have only passive marker data to use. So far I am trying ... kinematics. I extract movement traces from optitrack in .c3d format and convert them to .trc using MOKKA(I understand I could also export .trc files ...

I have only a .sto file which has emg data namely time and voltage and not any other data.My doubt is whether is it possible to convert the data I have to equivalent muscle force ?

What you can do is: extract the emg envelope and use it to constraint the possible solution that the SO or CMC finds. ... Could you mention what exact steps I should follow from the link given to convert the voltage data of emg to a .mot file which should have equivalent angle values

... that I have to work with is all stored in very specific .mat files (EMG, forces, markers). Which other tools exist to prepare this data for OpenSim use? Would I have to convert all this .mat files to a .c3d format so that I can use MOtoNMS? Another idea that ...

... to scale the signal by the maximum voluntary contraction so you can get values between [-1, 1] 1) remove DC (optional, because you use band pass) emg = detrend(emg); 2) band pass filtering https://github.com/RehabEngGroup/MOtoNMS/blob/master/src/shared/ZeroLagButtFiltfilt.m emg = ZeroLagButtFiltfilt((1/Fs), ...
