  • Differential and variable stiffness orthosis design with adjustment methods, monitoring and intelligence
    Patent number: 12440362
    Abstract: An assistive ankle foot orthosis is described. The AFO has a vertical shank member arranged laterally to a user's limb. The member carries a rotational bearing and a rotational element such as a pulley. The rotational bearing is lateral to a user's ankle. The pulley is connected to a footplate. The footplate can be actuated to provide joint movement assistance or resistance to the user upon rotation of the pulley. The AFO includes an ankle angle and angular velocity sensor and a pressure sensor located under the user's forefoot. The AFO includes a controller that computes an estimate of the user's peak joint power on the basis of a series of products of measurements of foot pressure and angular velocity.
