Abstract: A motor teaching system is provided with a force presentation robot for teaching motion in accordance with a predetermined motor pattern by guiding movement of a movable part of the body of a test subject, a brainwave sensor, and a computer that classifies a cerebral activity pattern into one of a plurality of classes that include motor imagery, based on a brainwave signal. The computer guides evoking contents of the test subject prior to teaching of the motor pattern, such that a classification result obtained in the period of teaching the motor pattern will be the motor imagery class.

Abstract: A body weight unloading apparatus according to an aspect of the present invention includes a first actuator, a second actuator, a first support member, a second support member, a sensor for measuring the imbalance between floor reaction forces respectively acting on the legs of a user, and a control device for controlling operations of the actuators. One end of the support members is respectively connected to the actuators, and the other end of the support members is fitted to the user such that unloading forces that are supplied by the actuators respectively act on the legs of the user. The control device controls the actuators so as to respectively generate unloading forces determined according to the imbalance between the floor reaction forces.
