ABSTRACT:
Head-mounted apparatus for measuring the movement of the spine or head about a substantially vertical axis, and also capable of indicating spine or head tilting. A headband firmly affixed to the head includes an indicia scale used in conjunction with a body reference indicator whereby the indicator is maintained stationary while the spine or head is rotated such that the relationship between the indicator and indicia scale represents rotative body movement. A gravity operated gauge also affixed to the apparatus measures tilting of the head with respect to the horizontal.
