Evaluation Of Human Segmental Body Volumes And Inertial Properties With Photogrammetry As A Basis For Gait Analysis

In order to be practically useful, gait analysis in patients with motor handicaps should provide information on joint loads, forces and moments. For accurate joint force estimates, mass and inertial properties of the limb segment must be known. A program for the determination of segmental mass and inertial properties was therefore set up, using stereophotogrammetry for the evaluation of segmental body volumes. The methodology using two stereo pairs of cameras is described. A 15 segment body model was defined with its segmental boundaries and its segmental anatomical axis systems.
