1. An apparatus for measuring the range of cervical motion about at least two axes of rotation including:

  • a frame for detachably mounting the apparatus to a human head, said frame having a nose pad adapted to be supported on the bridge of the nose as a reference location, and temple pieces adapted to be positioned on opposite side of a head for supporting and stabilizing the frame on the ears of a wearer; and

    a first vertical angle finder means and second angle determining means both coupled to the frame for determination of angle with respect to reference locations, respectively, using portions of the first and second means mounted on the wearer of the frame only, the angle finder means detecting rotations about a first axis and the second means detecting rotations about a second axis substantially perpendicular to the first axis.
