GRF for Inverse Dynamics

Post by Matthias Kunze » Sat Mar 19, 2011 7:37 am

Hi at all,

I have some collected force data (GRF) for hopping, but only the value for both leg together (not recorded for the left and right leg).
Is there an option to attend this while an Inverse Dynamic in OpenSim. I have separate CoP (calculated) for the left and right foot but only this 3D-GRF value.

Can anybody help me?

Regards,
Matthias

More detailed description:

lateral GRF ==> recorded for both legs in ONE value (GRFz)
horizontal GRF ==> recorded for both legs in ONE value (GRFx)
vertical GRF ==> recorded for both legs in SEPARATE values (GRFy_L + GRFy_R)

Hope this makes it clearlier.

Thanks for any help.

I have the same problem, I have a the measurement of GRF, COP and Moment of both legs together. Did you find a way to pass it to OpenSim format??

Regards,
Miguel
