A new invariant characterizing the postural alignment of young healthy adults
TypeCommunications avec actes
Introduction and objectives : postural trouble can have a negative impact on skeleton disorders for aging adults. The first step is understanding these aging postural troubles is to observe and quantify the erected posture of young healthy adult’s skeletons from radigraphies. However, posture studies in the literature focused on the alignment of the spine and pelvis segments , rarely including the head neither the lower limbs. Our studies aims to describe the postural alignment of young asymptomatic subjects from head to feet from bi-planar standing radiographies.

Estimation of spinopelvic muscles' volumes in young asymptomatic subjects: a quantitative analysis. AMABILE, Célia; MOAL, Bertrand; CHATARA, Oussama Arous; PILLET, Hélène; RAYA, Jose G.; IANNESSI, Antoine; SKALLI, Wafa; LAFAGE, Virginie; BRONSARD, Nicolas (Springer, 2017)Purpose Muscles have been proved to be a major component in postural regulation during pathological evolution or aging. Particularly, spinopelvic muscles are recruited for compensatory mechanisms such as pelvic retroversion, ...
AMABILE, Célia; NÉROT, Agathe; CHOISNE, Julie; PILLET, Hélène; LAFAGE, Virginie; SKALLI, Wafa (Columbia University, 2015)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 ...
A new quasi-invariant parameter characterizing the postural alignment of young asymptomatic adults AMABILE, Célia; PILLET, Hélène; LAFAGE, Virginie; BARREY, Cédric; VITAL, Jean-Marc; SKALLI, Wafa (Springer, 2016)Purpose Our study aims to describe the postural alignment of young asymptomatic subjects from head to feet from bi-planar standing full-body X-rays, providing database to compare to aging adults. Novelty resides in the ...
A 3D reconstruction method of the body envelope from biplanar X-rays: Evaluation of its accuracy and reliability NÉROT, Agathe; CHOISNE, Julie; AMABILE, Célia; TRAVERT, Christophe; PILLET, Hélène; WANG, Xuguang; SKALLI, Wafa (Elsevier, 2015)The aim of this study was to propose a novel method for reconstructing the external body envelope from the low dose biplanar X-rays of a person. The 3D body envelope was obtained by deforming a template to match the surface ...
AMABILE, Célia; CHOISNE, Julie; NEROT, Agathe; PILLET, Hélène; SKALLI, Wafa (European Society of Biomechanics, 2015)Rib cage volume and thorax density are useful both for clinical issues (Sverzellati et al. 2013) and for multi-segmental body modeling. In the latter case mean density is generally assumed, using data from Dempster et al ...
