A new invariant characterizing the postural alignment of young healthy adults

Abstract

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 [1], 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.
