Abstract

La présente invention concerne des dispositifs permettant de déterminer les écartements intervertébraux de la colonne vertébrale d'un patient. Ces dispositifs se distinguent en particulier en ce que les écartements intervertébraux du patient peuvent être saisis simplement lors de la marche dans un bâtiment ou en plein air. À cet effet, on place sur la peau du patient deux marques à la hauteur d'apophyses transverses pendant que le patient adopte une posture détendue, chaque marque étant constituée de deux repères disposés linéairement à distance l'un de l'autre. En outre, on dispose sur un support, à distance des marques, au moins une ou deux caméras numériques permettant de photographier, soit au moins une zone des deux marques des apophyses transverses, soit au moins une zone d'une marque, de façon à prendre et enregistrer des photographies des marques, d'une part pendant la posture détendue du patient, et d'autre part pendant la marche du patient. L'invention concerne également un dispositif de saisie du chemin parcouru par le patient. Le dispositif de l'invention comporte également un système informatique.
