A lower limb function training device which the patient themselves can use safely with no sense of fear, which is used to prevent or improve a drop foot contracture or to expand the excursion of a joint while preventing the patient from using it over an appropriate amount of exercise to the utmost, which allows the patient to select the type of exercise, and which enables measurement of state of the body. The device is provided with a contact sensor, a foot rest on which the feet of the patient rest and selectively moves back and forth or rocks vertically, a movement counter for counting the back-and-forth movements or vertical rocking of the foot rest, and a brake device for braking the back-and-forth movement or vertical rocking of the foot rest when the count reaches a preset value.
