Abstract: A multidirectional foot controller includes a base, a first platform, a second platform, and two pedals successively stacked and assembled together. The multidirectional foot controller is activated by having the two pedals depressed simultaneously, and then controls an externally connected endoscope to move forward or backward by a first platform, or controls the endoscope to move leftward or rightward by a second platform. By having only one of the pedals depressed, the multidirectional foot controller can change the field of view of the endoscope.

Abstract: A gait rehabilitation machine and a method of using the same for lower-limb rehabilitation. The gait rehabilitation machine includes: a frame; a rear supporting member provided at the frame so that the back side of a human body can lean against the rear supporting member; a thigh supporting member corresponding to a thigh of the human body and pivotally connected to the frame; a shank supporting member corresponding to the corresponding shank of the human body, pivotally connected to the thigh supporting member, and having a pedal to be stepped on by the human body; a knee supporting member corresponding to the corresponding knee of the human body and provided at the thigh supporting member or the shank supporting member; and a transmission device for driving the shank supporting member to move. Thus, a patient can do lower-limb gait rehabilitation exercise without using a suspension system.
