Hello Everyone,

I'm having a hard time locating the origins of the RRA pelvic residual recommendations shown in the chart at the bottom of the "Getting Started with RRA" page.

https://simtk-confluence.stanford.edu:8 ... d+with+RRA

Does anyone know how these recommendations were determined? I was hoping there might be a paper somewhere out there that explains what these recommendations are based on but I'm not finding it.

Thanks for the help!

Hi, Brad-

Those recommendations came from trial and error in our lab-- so there are no papers where this information came from.

The issue with residuals is that it depends on your model and data. The residuals could represent real forces and masses that have or haven't been included.

There's some discussion of residual forces in Section 3.1.3 of this paper: Hicks, J.L., Uchida, T.K., Seth, A., Rajagopal, A., Delp, S.L. Is my model good enough? Best practices for verification and validation of musculoskeletal models and simulations of movement.
