A method of motor reflex training a subject is provided. The method includes rotating a subject in a multi-axis rotational device comprising a pitch axis of rotation and a yaw axis of rotation. The rotation of each said pitch and yaw axis is independent of the other axis of rotation. The rotation velocity and acceleration around each said pitch and yaw axis controlled by a computer system. Said rotational device is configured to allow continuous rotation through more than 360 degrees around each said axis of rotation independently and simultaneously, while the subject performs a response test.
