Abstract
The invention relates to an orthopedic foot device with a connection part for the lower leg, a swivel joint () acting as an ankle joint () by means of which a foot part () is rotatably connected in the direction of dorsiflexion and the direction of plantar flexion to the connection part, with a damping arrangement () influencing the rotational movement about the swivel joint (), with a sensor arrangement for detecting action states of the orthopedic foot part, and with a control unit connected to the sensor arrangement which controls the damping arrangement (). The object is achieved by the fact that the sensor arrangement has an ankle-angle sensor which measures the angle between the connection part and the foot part (), an absolute-angle sensor () relating to the plumb line and a moments sensor () for determining the torque on the ankle joint () or a force effecting a torque on the ankle joint ().
