C3D file for going up and down stairs

[BBJ (zhou)]

Hi

I imported a C3D file of up and down stairs into Anybody, but there is no ground reaction force during the inverse dynamics analysis. Is this normal? Thank you in advance.

Best regards

Hi BBJ,

As i understand the problem, you have a c3d file with markers + force-plate data, but the forces are not applied when the model is running? and in the experimental setup you had a box up top of the plates.

This is because the foot is too high above the plate, in the force-plate file there is a possibility to set the height so that it can detect the foot even if it is high above the plate, so please simply try to increase this limit.

Best regards

Hi Søren

Thank you very much for your help. After I adjusted the height, the force appeared.
