How can I analyze L5/S1 compression?

Hello, I had studied Anybody about inverse dynamic analysis.

I collected muscle load data by muscle amplitude.

Then, I want know how to get L5/S1 compression data such as 3DSSPP.

How can I get those data? I'm using AMMR ver 2.3.1.

Thank you!

Hi @shim2906 and welcome to the forum!

The spine joint reaction forces are located Main.HumanModel.BodyModel.SelectedOutput.Trunk.JointReactionForce and here you can the L5SacrumProximoDistalForce which is the compression.

Best regards,
