[Musculoskeletal Analysis Case] Example of Closed Chain Problem (Analysis of Ladder Climbing)

Smoothly adjustable distribution degree! An analysis case of a subject's movements skillfully using both hands and feet to climb a ladder.

In AnyBody, the "soft constraint" option resolves motion analysis, and the concept of "virtual muscles" through the extension of the muscle distribution algorithm addresses the dynamics problems of redundant systems. In this article, we introduce a case study of analyzing "ladder climbing," where a closed state is continuously maintained. This analysis focuses on the subject's movements as they skillfully use both hands and feet to climb the ladder. In AnyBody, the ON-OFF switching of the "virtual muscles" that connect the person and the ladder occurs at the timing when both hands and feet engage with or detach from the ladder. Furthermore, for example, the distribution can be smoothly adjusted based on the degree of contact (horizontal axis).
