An estimation method of antagonistic ratios of functional effective muscles of upper limb based on maximum force distribution at end-effector

Functional effective muscle (FEM) theory can derive characteristics of limbs theoretically from detailed muscular strength. However, it is difficult to measure each muscular strength directly from outside the body. This paper proposes a new method for the estimation of muscular strength from maximum output force distribution at the end-effector of a limb. The proposed estimation method based on FEM theory is verified from the experimental results which are conducted on three subjects.
