Abstract: A gait trajectory guiding device of a gait rehabilitation apparatus is disclosed. The gait trajectory guiding device includes a pair of guideway actuating plates (11), which are arranged parallel to each other, and each of which is provided with a horizontal screw, and a pair of guideways (20), which are provided on each guideway actuating plate. Each guideway is individually moved by rotation of the corresponding horizontal screw in the longitudinal direction of the guideway actuating plate. The device further includes footboards (30), which are coupled to the corresponding guideways such that the front and rear parts of each footboard are individually adjustable in height. Therefore, the footboards are actuated by the guideways along trajectories similar to the movement of the feet of a person when actually walking, thus enabling a user to conduct gait training in a correct walking motion, thereby increasing rehabilitation effect.

Abstract: Provided are a gait trainer which provides exercise prescription and an exercise prescription system using the gait trainer. The gait trainer comprises a display, pedals on which user's feet are placed, a control unit which receives physical information about the physical condition of the user while the pedals are moving, defines an optimal exercise prescription based on the physical information, and provides the defined exercise prescription to the display. The control unit accesses a server belonging to a health-related organization through a predetermined network, and defines the exercise prescription with the aid of the health expertise received from the server. Since the exercise prescription suitable for the user is provided, exercise efficiency is maximized and possible dangerous health situations can be prevented.
