Re: RRA tool

Hi Ursula,
I am simulating a healthy walking trial with my experimental data.
I too am having issues with model sinking and sliding a bit during the RRA simulation. GRFs have been applied on both the legs. The RRA residuals are also within the OpenSIM standard range, but it is the alignment of GRF after RRA that I am concerned with. The application of ground reaction forces after RRA is severely affected and they do not act on the foot but somewhere in space. Can you please help or suggest something?

Regards,
Shivangi Giri

You are most likely performing RRA when not all forces are available. You should only perform RRA during single stance or double support when all forces from forceplates are available.
