Abstract

L'invention concerne des systèmes et des procédés pour estimer l'attitude, l'angle de tige, la vitesse et/ou la position d'un dispositif prothétique de membre inférieur sur la base de données ou de mesures provenant d'une IMU. Les systèmes et les procédés peuvent réduire ou minimiser la dérive. L'attitude, l'angle de tige, la vitesse et/ou la position estimés de la prothèse de membre inférieur peuvent être utilisés pour commander une ou plusieurs fonctions du dispositif prothétique de membre inférieur.
