Bottom up vs top down model

Hi, I am modelling static lifting activities. I want to know if the Anybody model is a top down model when calculating spinal forces. And is it possible to calculate spinal forces using a bottom up approach so GRFs would be used in obtaining spinal forces?
Thank you

Hi Sajjad,

You can use GRF to calculate the spinal forces. In your mocap model, you would need to ensure that the residuals are applied to the thorax. Then, you would be able see the effect of the GRF on the spine.

You can do so using the define statement:


Please see here for more info: The AnyMoCap Framework — AMMR v2.4.2 Documentation.
