1. A diagnostic system for detecting and indicating cranial movements in a human subject whose brain case is composed of a plurality of articulated bones which define the cranium, which bones normally undergo oscillatory motion, said system comprising:

  • (a) reflector elements placeable on selected bones of the cranium whereby the elements are caused to vibrate as a function of the oscillatory motion of these bones;

    (b) an infrared camera directed at the cranium which during a test period emits infrared light that is reflected by the elements and is picked up by the camera to produce in an image analyzer information regarding relative motion between the vibrating elements; and

    (c) a computer to which said information is supplied, said computer being programmed to reconstruct the relative motion as a diagram illustrating cranial movement during the test period.
