Abstract

Cette invention est un système de détermination des centres de pivotement pour les articulations proximales et intermédiaires d'un squelette appendiculaire. Le système comprend un moyen de fixation d'un marqueur unique (34) sur un os, un moyen de déplacement d'une partie du squelette appendiculaire selon une séquence faisant intervenir au moins un mouvement, un moyen de collecte de points de données (42) corrélant la position et l'orientation du marqueur, un moyen de sélection d'un certain nombre de positions du squelette pendant la séquence utilisant les points de données collectés (44), un moyen d'affectation d'une valeur à chaque posture représentant la position, ainsi que l'orientation du marqueur en un point ou une référence prédéterminé(e), ainsi qu'un moyen de détermination des coordonnées des centres de rotation des articulations proximales et intermédiaires utilisant les valeurs affectées.
