Functiional Evaluation of Effective Leg Muscular Strength Based on a Muscle Coordinate System Composed of Bi-articular and Mono-articular Muscles -Estimation of Functional Effective Muscular Strength from Output Force Distribution-

摘要

It has been reported that, in the two-joint motor link system of the human arm, complicate muscular alignments were simplified into three antagonistic pairs of six muscles including mono-and bi-articular muscles and these six muscle strengths were defined as functionally effective muscular strengths (FEMS), and the output force distribution exerted at the endpoint of the two-joint link system comes hexagonal shape, and further the six FEMS could be estimated based on the hexagonal characteristics of the output force distribution.
