HEAD AND NECK POSTURE MEASUREMENT DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a head and neck posture measurement device and method, allowing easy measurement of a three-dimensional posture of the head and neck of a measured person as versatile data capable of being reproduced many times via a time and a place.SOLUTION: This head and neck posture measurement device includes: a head and neck front projection height measurement means measuring a vertical height from a measurement reference plane F that is a bed B face to an earhole Y of a measured person M having a supine posture as a head and neck from projection height H; a head and neck stoop angle measurement means measuring an angle at which a measured point P that is a predetermined one point on the face part ridge line L of the measured person M having the supine posture is inclined around the earhole Y to a vertical plane V2 passing the earhole Y from the measurement reference plane F as a head and neck stoop angle &thetas;2; and a head and neck rotation angle measurement means measuring an angle at which the measured point P in a measured posture rotates around the head top point Q to a vertical plane V1 passing the face part ridge line L of the measured person M having the supine posture from the measured reference plane F as a head and neck rotation angle &thetas;1.
