In the measurement of human upper limb, the position for the center of shoulder joint can be supposed by comparative position to acromion.

在人体测量中，肩关节中心的位置要通过其与肩峰的位置关系进行估测。

Distance between the acromion and the center of the shoulder was calculated by the data of this experimentation. The absolute value of error was smaller than 2.7 cm.

通过实验得出了肩关节中心与肩峰位置之间的近似距离，实际测量误差的绝对值均小于2.7 cm。

Conclusion the measurement of acromion zygoma distance and shoulder width, which provides significant reference data for the design and improvement of cervical rehabilitation pillow.

结论：肩颧距及肩宽数据测量，为颈曲康复枕设计和改进提供了重要参考依据。
