The invention relates to a device and method for assisting a subject to perform a motion such as a lift. The invention comprises a first anchor attachable to a first side of a joint of the subject's body, a second anchor attachable to a second side of the joint; and an elastic member connecting the first anchor and the second anchor, such that articulation of the joint in a first direction causes deformation of the elastic member and storing of energy, and articulation of the joint in a second direction causes relaxation of the elastic member wherein the energy is released and assists the subject to perform a motion in said second direction. The invention may be used at a subject's waist, ankle, wrist, knee, hip, elbow, shoulder, and/or at least one joint of the back and/or neck.

L'invention concerne un dispositif et un procédé permettant d'aider un sujet à accomplir un mouvement tel qu'un soulèvement. L'invention comprend une première ancre pouvant être fixée à un premier côté d'une articulation du corps du sujet, une seconde ancre pouvant être fixée à un second côté de l'articulation ; et un élément élastique reliant la première ancre à la seconde ancre, de sorte que le mouvement d'articulation de l'articulation dans une première direction entraîne la déformation de l'élément élastique et le stockage d'énergie et que le mouvement d'articulation de l'articulation dans une seconde direction entraîne le relâchement de l'élément élastique et la libération de l'énergie et aide le sujet à accomplir un mouvement dans la seconde direction. L'invention peut être appliquée sur la taille, la cheville, le poignet, le genou, la hanche, le coude, l'épaule et/ou au moins une articulation du dos et/ou du cou.
