Wrist model_Static Optimisation

[Ankit Verma]

Hi Everyone
I have downloaded the Delp model of Wrist and have been trying to calculate the muscle forces using Static Optimisation in Wrist Model. I have given mass and intertial properties from benjamin's research paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5597339/). In model I am giving motion to 3 degree of freedom out of 7 degree of freedom available (three joint of index finger). In one case, I have performed the Static Optimisation while giving Reserve Actuator only at actuated dof and in other case I have performed static optimsation while giving reserve actuator at all the degree of freedom. In both cases, I am getting different results.

Can someone explain, why ? what is the correct way to provide reserve actuator at only actuated degree of freedom or on all the degree of freedom ?
