Title
(EN) PROSTHETIC FOOT WITH TUNABLE PERFORMANCE
(FR) PROTHESE DE PIED PRESENTANT DES PERFORMANCES ACCORDABLES
Abstract
(EN)
A resilient lower extremity prosthesis comprising a foot, an ankle and a shank above the ankle is provided with an artificial muscle (190) on the shank (191) of the prosthesis for storing energy during force loading of the prosthesis in the active propulsion phase of a person's gait and in the later stages of stance-phase of gait releasing the stored energy to aid propulsion of the person's trailing limb and body.
(FR)
L'invention concerne une prothèse d'extrémité inférieure souple comprenant un pied, un ancrage, et une tige située au-dessus de l'ancrage, ladite prothèse étant dotée d'un muscle artificiel (190) sur la tige (191) de la prothèse, ce qui permet de stocker l'énergie lors du chargement de la force de la prothèse dans la phase de propulsion active de la démarche d'une personne et dans les étapes supérieures de la phase de maintien de la démarche, l'énergie stockée est libérée de manière à favoriser la propulsion du membre d'appui et du corps de la personne.
