摘　　要：目的获取上楼梯运动过程中国人下肢关节活动范围的统计学数据,从而为大屈曲度人工关节设计提供依据。方法设计常规楼梯实验装置,利用运动捕捉系统(Optotrak Certus,NDI)和三维测力台(AMTI,Bertec),建立系统地测量上楼梯过程中下肢运动的方法,并应用此方法对40例样本进行测量。结果计算获得了40例样本在上楼梯过程中,髋关节、膝关节及踝关节在1个运动周期内沿各方向上关节角的变化规律及活动范围,其中髋、膝、踝关节在矢状面上活动范围分别是-1.6°～66.7°,0°～91.4°,-20.8°～22.4°。结论上楼梯运动过程中,髋、膝、踝关节在矢状面上活动度最大,且髋关节和膝关节屈曲度最大。与水平路面上正常行走和慢跑运动中关节运动范围比较,上楼梯运动中,髋关节和膝关节在矢状面上运动范围均较大。Objective To obtain the statistical data from the range of motion in lower limb of the Chinese people during their stair ascent so as to provide references for the design of artificial joints with large range flexion.Methods Common staircase as an experimental device was designed,and motion capture system（Optotrak Certus,NDI）and 3D force plate（AMTI,Bertec）were used to establish a systematic method to measure the lower limb motion from 40 subjects during stair ascent.Results The variation of joint angle and range of motion in hip,knee and ankle joints for the 40 subjects in different directions within one cycle were obtained and calculated.The range of motion in hip,knee and ankle joints at the sagittal plane were-1.6°~66.7°,0°~91.4°,-20.8°~22.4°,respectively.Conclusions During the movement of stair ascent,the range of motion at the sagittal plane in hip,knee and ankle joints reached the maximum,with the most flexion in hip and knee.Compared with the movement during walking and jogging on flat road,the range of motion in joints both in hip and knee at the sagittal plane were larger during stair ascent.
