目的：探索眼部运动时，面部相关联部位运动的特点，为评价周围性面瘫时面部联动提供参考。方法健康志愿者22人（45-60岁），利用自行设计的“基于运动捕捉的面部运动三维动态定量分析系统”记录并分析“用力抬眉”“用力闭眼”两个表情动作中，面部相关标记点的运动，使用移动距离（Smax）及运动速率（Vmax）两个参数描述其运动。结果1.“用力抬眉”动作，眉弓点左9.75mm，24.11mm/s，右10.14mm，25.87mm/s；除眼周标记点外，余标记点均有运动，移动距离为3.65mm至4.46mm，鼻唇沟点的运动速率明显大于其他标记点，左60.60mm/s，右62.70mm/s。口角点、鼻唇沟点运动距离、速率与眉弓点对应参数间线性相关关系强。2.“用力闭眼”动作，上眼睑点移动距离和速率最大，左10.56mm，87.68mm/s，右10.54mm，81.83mm/s。除眼周标记点外，余标记点均有运动，移动距离1.58mm至1.92mm，运动速率分布于11.40-14.76mm/s。口角点、鼻唇沟点运动距离、速率与上眼睑点相关参数线性相关关系差。结论健康人进行眼部主动运动时，会引起面部其他标记点发生运动，其获得最大距离、最大速率的时间一致，用力闭眼动作中运动幅度最大的点在口角点，用力抬眉动作速率最大点在鼻唇沟点，运动距离最大的点在下唇中点。

Objective This is a preliminary study in which we try to analyze the movements of facial markers which we set around the Rima Oris quantitatively in ocular predominantly facial expressions, and try to find out the influencing factors. Methods Twenty two healthy volunteers, aged from 45 to 60 years, took part in this study. A 3-D dynamic quantitative analy-sis system of facial motion （3-D ASFM） based on motion capture technique was used. Maximum moving distance （Smax） and maximum velocity （Vmax） were measured to describe facial movements associated with eyebrow rasing and tight eye shut. Re-sults 1. In eyebrow raising, Smax and Vmax of the eyebrow marker were 9.75 mm and 24.11mm/s on left and 10.14mm and 25.87mm/s on right. For associated movements, Vmax of the“nasolabial groove”marker was greater （left：60.60 mm/s;right：62.70 mm/s） than other markers （23.11-25.73 mm/s）. The Smax of these 6 markers were 3.65-4.46 mm. Linear correlation between the Smax and Vmax among the“corner of the mouth”,“nasolabial groove”and“eyebrow”markers. 2. In tight eye shut, Smax and Vmax of the“angulus oculi medialis”were smaller （left：1.33 mm and 13.29 mm/s;right：1.46 mm and 14.64 mm/s, respecxtively）, while those of the”palpebra superior”were greater （left：10.56 mm and 87.68 mm/s;right：10.54 mm and 81.83 mm/s）, than other markers （5.73-8.36 mm, 53.31-63.03 mm/s）. The Smax and Vmax of other markers were 1.58-1.92mm, 11.40-14.76 mm/s. There was no linear correlation between the Smax and Vmax of the“corner of mouth”,“nasolabi-al groove”and“palpebra superior”. Conclusions In healthy people, movement of mimetic muscles around the eye are associ-ated with movements of markers in other areas of the face, with similar timing in Smax and Vmax. In tight eye shut,“corner of the mouth”markers move faster and have longer moving distance than other facial markers. In“lifting eyebrows”, the“nasola-bial groove”moves faster than facial markers, although with sm
