Computer Methods in Biomechanics and Biomedical EngineeringRésumé
Sagittal malalignment is associated with increased disability and can lead to postural troubles. The latter is often the result of an inadequate weight distribution on the spine and trigger compensatory mechanisms. No study to date has provided reference values for the alignment of centers of mass (CoM) of different body segments in asymptomatic subjects. The use of a bi-planar X-ray system (Dubousset et al. 2010) combined with 3D reconstruction of the external body shape (Nérot et al. 2015) allows for computation of the body segments’ CoM. The aim of this study was to provide baseline values for the position of each segment’s CoM compared to the gravity line (GL) in the sagittal plane.

The 3D body envelope was obtained by deforming a template to match the surface ...

AMABILE, Célia; CHOISNE, Julie; NÉROT, Agathe; PILLET, Hélène; SKALLI, Wafa (Elsevier, 2016)Body segment parameters (BSP) for each body's segment are needed for biomechanical analysis. To provide population-specific BSP, precise estimation of body's segments volume and density are needed. Widely used uniform ...
