Estimation of musculotendon properties in the human upper limb

Abstract

A method for the estimation of musculotendon properties in the human upper limb is discussed. The method consists of a two-phase, nested optimization procedure in which the values of peak isometric force, optimal muscle-fiber length, and tendon slack length are calculated for each musculotendon actuator, knowing muscle volume and the minimum and maximum physiological lengths of the actuator. The model calculations are compared against measurements obtained from anatomical studies reported in the literature.
