Inverse dynamics ankle joint torque is almost zero

​I used the VICON three position capture system and the AMTI force measuring board to record the C3D file of the upstairs process. The file is imported into ANYBODY, and the lower limb model is used to conduct inverse dynamic analysis on the process of going upstairs. The obtained joint moments are quite different from those described in other literatures, especially the ankle joint moments, which are almost zero,only a few tenths. How can I get the correct joint moment?

Hi lifugui,

Unfortunately, I am not able to see the images. Could you please upload the images again?
It is possible that maybe the force plate data is not recorded correctly during the measurement. This maybe a realistic explanation of the large difference that you may be seeing. Can you also compare your ground reaction force data to the literature values and see if they are similar?

Best regard,
Dave
