Abstract
In this study, we analyzed the burden of each muscle for the simple motion around the knee joint. This analysis method was used the angular momentum of each muscle and the driving power around the knee joint. We think that the angular momentum represents the intensity of the muscle motion for the driving power around the knee joint. Also, we used Hill type model to muscle model in 3D lower limbs musculoskeletal model. Then, we verified the value and usability of this analysis method by using those analysis result. The value and usability of this method was verified by comparing it with the conventional method. The conventional method was used the driving torque around the knee joint and driving torque of the muscle.
