GM Foot gait data in GitHub repertory

Main Forum

Hello,

I'm currently working on a FE model of the ankle based on the GM foot model. My goal is to analyse contact behavior on the talus by applying as input joint kinematics and JRFs extracted from AnyBody. For this purpose, I'm using the MoCap example available in the GitHub repertory of the GM foot, as it already includes input data and a functioning model.
Regarding the input data, I would like to make sure that this is from the same subject the template model is created from. Could you confirm this to me?
My reasoning behind this assumption is:
-subject-specific information from the gait trial are weight (76kg) and foot length (23.5cm)
-the model standard foot length is 23.5cm
-the foot model is based on one of the 6 subjects included in the study published (The Glasgow-Maastricht foot model, evaluation of a 26 segment kinematic model of the foot) where only two subjects have a foot length of 23.5cm

Putting together those points would lead me to assume that the gait data available in the repertory are from subject GCUC01 (whose weight is 76kg and foot length 23.5cm)

I just want to make sure that the foot model doesn't need any scaling as the gait data would come from the same subject.

Additionally, is this gait data the average of multiple trials or is it a single trial?

Thank you so much for the help

Hi Sami,

Welcome to the AnyScript Forum! And apologies for the delay in reply.

I am not sure which subject was used for the making the model but rest assured that the model on the GitHub repository will be scaled to the subject whose motion data has been provided in the repository. So, you don't need to do anything in particular.

It could very well be that it is subject GCUC01 based on what you say.

The gait data is from a specific trial and not an average of multiple trials.

Just a note, that the GM foot model is missing some of the updates in general to the leg model and we are aware that there are some issues with muscle usage during gait. This is not ideal for your research. We are working on updating this model but I can't promise when it will be available.

Best regards,
Dave
