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

Abstract

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.

An estimation of strength ratios of antagonistic muscle groups based on variable moment arm

“…However, PCSA and EMG include non-linear factors, and these methods require special devices such as myoelectric sensors, magnetic resonance imaging devices and computed tomographic scanning. The authors proposed a strength estimation method of functionallyclassified muscle groups of a limb [4]. This is the method without complicated preconditions.…”
