A walking training apparatus 1 includes a leg robot 2 attached to a leg of a walking trainee, a motor 261 configured to rotationally drive a knee joint 22 of the leg robot 2, a control unit 332 configured to control the motor 261 so that the motor 261 rotationally drives the knee joint 22 in a leg-idling period in a gait motion of the walking trainee, a motor torque detection unit 262 configured to detect a motor torque, the motor torque being a torque generated by the motor 261, and a determination unit 333 configured to determine whether or not the walking trainee is in a spasticity state or a rigidity state by using a value of the motor torque detected in the leg-idling period by the motor torque detection unit 262.
