Abstract:
1. A leg rehabilitation system having a game function, the system comprising: a back plate for supporting a patient; a pair of variable frames connected to a bottom surface of the back plate wherein the pair of variable frames are configured to be elevated horizontally and the back plate is configured to be inclinable at an angle with respect to the variable frames; an inclination controller for hinge-connecting the bottom surface of the back plate to one end of the variable frame wherein the inclination controller controls inclination of the back plate with respect to the variable frame; a base frame connected to the bottom surface of the variable frame to be supported above the ground surface; a plurality of variable link parts for connecting the variable frame to the base frame and rotatably hinge-connected to each of the variable frames and the base frame; a stepper part having two foothold parts connected in pair, the stepper part being extended from the bottom portion of the back plate in such a manner that a patient can move the two foothold parts downwardly in turn with legs of the patient, wherein at least one of the foothold parts includes a load sensor for sensing a load transferred to each foothold part according to circular motion of the legs when the patient alternately moves the legs and movement speed of the foothold parts connected with each other; a controller configured for generating game data based on load data according to the load sensed by the load sensor and the speed data according to the movement speed; and a display unit for displaying game elements corresponding to the game data generated by the controller wherein the game elements includes graphical game elements.
