"Manually" scaling GRF in gait2392 would provide reliable results?
Posted: Thu Nov 10, 2016 12:30 pm
Hello,
I will be trying to simulate how an added weight in the form of an orthosis in the scaled gait2392 model would affect the various muscles and metabolic cost.
I initially thought of adding the orthosis and contacts to the model, but I've seen many answers in this forum suggesting that performing CMC with contacts is rather complicated and could require custom code to run.
Considering the orthosis is "evenly displaced" around the whole lower body from feet to torso, how "unreliable" would it be if I just evenly increased the ground reaction forces already available for the model?
If the scaled model is ~73Kg and the orthosis is 10Kg, could I "simulate" the model as a 83Kg subject by running a matrix multiply of (83/73 = 1.137) to all the values in the grf file?
Thank you.
