目的探讨左右对称性对人脸三维运动位移的影响。方法采用专家视觉运动分析系统对42例受试者的位移数据进行分析。右和左三维面部位移进行量化。结果整个面部的三维位移左侧明显大于右侧。面部左右两侧的三维位移差范围为0.48 mm至2.28 mm。在鼻皱纹表达过程中，2 cm下瞳孔标记物的左移位显著大于右移位。结论在建立正常面部运动范围的基线时，必须考虑位移差异的范围，沿着平均三维位移测量。
Objective This study examined the right to left symmetry of the displacement of three-dimensional movement of the human face. Methods Displacement data on 42 subjects was collected and analyzed with the Expert Vision Motion Analysis System. Right and left three-dimensional facial displacements were quantified. Results Significantly greater left than right three-dimensional displacement across the whole face was measured. The three-dimensional displacement difference ranged from 0.48 mm to 2.28 mm between the right and left sides of the face. The 2-cm inferior pupil markers during the nose wrinkle expression had significantly greater left than right displacement. Conclusion The ranges of displacement differences, along with the mean three-dimensional displacement measures, must be accounted for in the creation of a baseline of the range of normal facial movement.
