We previously reported that the output force distribution at the wrist demonstrated in the hexagonal shape, and the characteristic of the hexagonal output force distribution was suggested by the theoretical analysis of the two joint link model with the muscle coordinate system. The muscle coordinate system is composed of the three pairs of antagonistic muscles consist of mono- and bi- articular antagonistic muscles. The difference between distribution calculated muscle coordinate system and distribution calculated joint coordinate system consists of two joint torques was clarified. The individual functional effective muscular strengths could be evaluated from the hexagonal output force distribution. In this study, the relationship between output distribution and muscular strengths under approach by muscle coordinate system was more clarified. Proposal method may be of use when prescribing the portable measuring system of the functional effective muscular strengths.
