An apparatus for lower-limb rehabilitation training of a patient with lower limb paralysis and a rehabilitation apparatus using game device. The invention measures the usage of the paralyzed lower limb, and based upon the measurement, forces patients with limb paralysis to use partially paralyzed lower muscles which they are not likely to use. The apparatus can measure the weight load and the angle of the joint, and by using the measure values as variables, display the condition of paralysis to the patient so that he/she can recognize his/her present condition of paralysis, and enable the user to training through feedback.
