The quick-release method for estimating the moment of inertia of the shank and foot

Abstract

The accurate determination of body segment parameters is a problem of crucial importance to biomechanics research. Within the limitations of a rigid-body anthropometric model, the calculation of forces and torques from movement data can be only as valid as the data concerning the mass, length, and inertial parameters used in the calculations. It is essential, therefore, that systematic investigations be made of any techniques that enable body segment parameters to be estimated in the same living subjects used in experiments from which movement data were collected.
