摘要：

      摘要 目的：研究我国成年男子头颈部前屈运动特征，其中包括头部质心轨迹与前屈角度。 方法：根据中国成年人人体尺寸国家标准GB10000-88，选取5/50/95三个百分位志愿者各10例；受试时，志愿者躯干保持不动，头颈部在矢状面内自然前屈；使用Raptor-4运动捕捉系统捕捉志愿者身上所贴标志点的坐标，通过对标志点坐标计算得出头部质心与转动角度。 结果：①获得了5/50/95百分位成年男子头颈部前屈运动特征，运动特征数据与志愿者身高成正相关；②将运动特征数据取综合均值作为装置设计基准，3个百分位数据相对于综合均值的误差最大为10.08%。 结论：通过头颈部前屈运动特征研究，可为颈部康复或防护装置设计提供边界条件。

Abstract:

      Abstract Objective：To study the characteristics of adult male head and neck flexion movement, including the barycenter track and rotation angle. Method：According to the human dimensions of Chinese adults standard GB10000-88, we selected 3 groups of 5/50/95 percentile volunteers, with ten volunteers per group. During the test, the trunk of the volunteer remained stationary, the head and neck flexed naturally in sagittal plane. The volunteers were tagged with some markers which can be captured by Raptor-4 analyser. Then we obtained the barycenter and rotation angle by calculating the coordinates of the markers. Result：①The features of adult male head and neck movement were got. The motion characteristics and the height of volunteers presented positive correlation; ②Assume the synthetic average of motion characteristic data as the design benchmark of the device. The maximum deviation of the three percentile data to the comprehensive mean value is 10.08%. Conclusion: Through researching on the characteristics of the head and neck forward bending movement, we proposed boundary conditions for the neck rehabilitation and protection devices design.
