Re: Inverse Dynamics Using a single force plate

Thank you sooo much!

This has actually been a life saver. I have tried it on mine and got the same results as you.

Thank you!

Re: Inverse Dynamics Using a single force plate

Hi Mohammadreza, Thank for you reply, I have tried in the stance phase however this is also not working. I have shared my model and all the required data here. The original data was received in a matlab structure. I created trc and mot files from this structure. The original model is scaled from one...

Re: Inverse Dynamics Using a single force plate

Hi Mohammadreza, Thank you for your reply. I have a feeling it is something to do with the application but I have the exact same settings as in the link you attached and I am using the same model I have for other simulations which have worked. Any other advice would be greatly appreciated as I am st...

Inverse Dynamics Using a single force plate

HI there, I am currently struggling with my inverse dynamics process using a typical able-bodied model. I have force plate data for only one force plate and marker data for a full stride. My inverse kinematics are complete and look to be correct. I have checked all of my units and made sure they are...

screen resolution too low for gui

Hi there,

I am struggling as when I run the code to launch the gui, it pops up with the top half cut off.

I think this is because my screen resolution is too low. I cannot find anything in the code to help me resize the gui.

Please can you help with this problem?

Thank you!

change in walking direction affects inverse kinematics

hi everyone, I am struggling with an issue with my inverse kinematics. I have a dataset of c3d files which I have converted to trc and mot files. I have ensured the global rotations have been performed to match the coordinate systems during the conversion. However, when I perform inverse kinematics,...

Re: Predict prosthetic knee torque required

Hi Nick, Thanks so much for your reply! Yes the device will be passive. I agree inverse would be the simplest approach, however I don't have experimental gait data of amputee gait, only able-bodied. As such I was worried when doing inverse dynamics the effects of a passive prosthetic foot vs able-bo...

Predict prosthetic knee torque required

Hi everyone, I am tyring to predict the torque my prosthetic knee design will require to replicate able bodied kinematics. I wish to ensure the hip torque is the same as able-bodied and reach the same able-bodied kinematics. So I have my hip torque to apply to segment model, I have the kinematics I ...

Removing a body from the model

Hi there, I was just wondering whether it was possible to remove a body from a generic model using API on matlab. I wish to remove the calcaneus, talus and toes and replace with a prosthetic foot. Is there a function to achieve this on matlab, I can only find API suggestions on adding a body. Many t...

Removing a body from the model

Hi there, I hope you are well. I am looking to change the foot bodies out and replace them with a singular prosthetic foot. However, I cannot seem to find a function on matlab API to remove a body, only to add or edit. Is it possible to delete a body from the model before adding a different one back...
