Abstract: A device for the therapeutic treatment and/or training of the lower extremities of a human having driven and controlled movement devices, which are connected to a stationary frame and include holding members for fastening of one extremity. The holding members can be moved independently of one another along walking trajectories. The movement devices each include a pivot arm pivotable into different elevations, and the pivot arm is rotatably connected to one single sled on a linear track. A first rotational drive is attached to a single sled and is connected to the pivot arm for changing the elevation of the respective holding member. The pivot arm includes a second rotational drive for changing the inclination of the respective holding member and the sled is connected to a linear drive for changing the longitudinal position of the respective holding member.
