In this study. we improve the existing model for force distribution over the muscles by considering reflex excitation as a nonvoluntary mechanism of our neuromuscular system. The improved model can explain the large difference between biological torque and experimentally optimized assistive torque profiles. Accordingly. https://www.spidertattooz.com/Fanimation-MAD8514-TriAire-52-Indoor-Outdoor-Ceiling-Fan/
