In this paper, the angles are measured for bending so that the chin touches the chest by bending the neck and extension, which takes a posture as if raising the neck and looking at the ceiling. The basic bending angle is 45-50°, and the maximum range of motion is 80-90°. The angle of extension is also 40°~50° as default, and the normal is limited to 70°.
본 논문에서는 목을 구부려 턱이 가슴에 닿도록 하는 굽힘과, 목을 들어 천장을 보는 것처럼 자세를 취하는 폄에 대하여 각을 측정한다. 굽힘의 각도는 45~50°가 기본이며 최대의 가동 범위는 80~90°이다. 폄의 각도 또한 40°~50°가 기본이며 정상은 70°로 제한된다.
