It is important to be caught a loading process during a care work with a unstable posture in worker's body quantitatively for its evaluation from dynamics viewpoint. Particularly, a waist part in trunk system often causes a disease because of the over load during a care work supporting a body of a patient. In order to clarify the mechanism of its over load, there are many evaluations by the joint moment method. However, the activation level of muscle against this over load is hardly estimated by joint moment method. A parameter such as strain of muscle to estimate its activation level is most effective. In this research, multi-body dynamics analysis of a waist part in consideration of muscle contraction during a care work is performed. Then, the activation level of muscle is estimated by the animation of motion of trunk system.
