The method according to the invention for measurement of subject's sway is characterized in that the body of the subject (1) standing on a supporting surface (2) is coupled (6, 7, 8) to an adjacent stick or equivalent (3) joint to the supporting surface (2) by a tilting joint (4, 5) of two degrees of freedom, and the sway motion transmitted to the stick or equivalent (3) is detected (11). In the measurement, the stick (3) is modelling a rigid joint. The invention concerns also a corresponding apparatus. By means of the invention the real sway motion of the subject may be measured quite accurately and converted to digital data for further processing, printing (17), saving and analyzing.

L'invention concerne un procédé permettant de mesurer le balancement d'un sujet. Selon ce procédé, le corps de ce sujet (1) qui se tient sur une surface d'appui (2) est couplé (6, 7, 8) à une tige adjacente ou à tout autre accessoire équivalent (3), cette tige étant reliée à la surface d'appui (2) par un joint basculant (4, 5) avec deux degrés de liberté. Le mouvement de balancement transmis à la tige ou à l'accessoire équivalent (3) peut ainsi être détecté (11), ladite tige (3) se présentant sous une forme identique à celle d'un joint rigide. Cette invention, qui concerne également un appareil correspondant, permet de mesurer avec une relative précision le mouvement de balancement réel dudit sujet, puis de convertir cette mesure en données numériques à des fins de traitement, d'impression (17), de sauvegarde, et enfin d'analyse.
