Abstract

L'invention concerne un dispositif servant à effectuer une mesure quantitative de la position de la colonne vertébrale sur le corps humain. Au moyen de ce dispositif, la position explicite est déterminée par palpation de chaque corps vertébral et détermination des coordonnées spatiales x, y et z. Deux rails de guidage verticaux (1, 1') qui sont fixés par une de leurs extrémités à une plaque de base (10) se trouvent à une distance mutuelle légèrement supérieure à la largeur d'un corps humain. Un élément support horizontal (3), pouvant être déplacé verticalement de manière continue et pouvant être bloqué, est placé entre les rails de guidage (1, 1'). En outre, un élément de palpation (4) est placé indirectement sur l'élément support (3). La lecture des coordonnées (x, y, z) de l'élément de palpation (4) s'effectue soit de manière analogique par l'intermédiaire d'une échelle de mesure soit numériquement, les données mesurées étant alors transmises à un ordinateur qui représente graphiquement les différentes données.
