Systems and methods for sensing actuating a prosthetic ankle are disclosed. In one example, the system, such as an actuated prosthetic ankle joint, detects that the user has moved to a relaxed position, such as sitting, reclining, crawling, or leaning. In response, the actuated prosthetic ankle joint actively adjusts the angle between the members of the ankle to a relaxed state. The system may further detect when the user has moved to exit the relaxed position, and may actively adjust the angle between the members of the ankle to an exit state. In another example, the system, such as an actuated prosthetic ankle joint, detects the surface angle and actively adjusts the members of the ankle to a preferred angle according to the respective slope of the incline/decline.

Systèmes et procédés pour détecter l'actionnement d'une prothèse de cheville. Dans un premier exemple, le système, tel qu'un joint de prothèse de cheville articulé, détecte que l'utilisateur s'est déplacé vers une position de repos, telle qu'une position assise, une position inclinée, une position couchée ou une position appuyée. En réponse, le joint de prothèse de cheville articulé règle activement l'angle entre les éléments de la cheville dans un état relâché. Le système peut en outre détecter que l'utilisateur s'est déplacé pour sortir de la position de repos, et peut régler activement l'angle entre les éléments de la cheville et un état de sortie. Dans un autre exemple, le système, tel qu'un joint de prothèse de cheville articulé, détecte l'angle de surface et règle activement les éléments de la cheville à un angle préféré selon la pente respective de l'inclinaison/déclinaison.
