A walking-trainer device for persons with a walking disorder to relearn walking has a movable tread surface and a display unit for displaying target indications of the corresponding and consecutive foot positions for movements made by a person walking on the tread surface. The target indications have the form of a number of consecutive patterns located above a target surface at the height of and in the longitudinal direction of the tread surface moving in the direction of the person, which visibly move from a distance of between 0.5 m and 0.5 m, preferably between 15 m and 5 m and more preferably between 0.7 m and 2.5 m, from the target surface in the direction of and over the tread surface up to the feet of the person. The speed of movement of the patterns is substantially equal to the speed of movement of the tread surface.
