ABSTRACT:
A device and process for measuring cervical range of motion about three axes comprises a frame which is supported on the nose of a subject and which has side temple pieces for locating the frame on the wearer's head. Cervical range of motion of a wearer's head can be measured through the use of gravity type angle meters and a magnetic type angle meter which are mounted on the frames and easily referenced back to the frame. The magnetic type angle meter is mounted above the head on a removable arm, which is supported on the frame. A magnetic field is created using magnets mounted on the subject to obtain reliable head rotation readings. The magnetic type angle meter can be removed, and an arm which is mounted on the frame and extends above the head of a wearer and which when coupled with a locator arm can determine a forward head position measurement.
