摘　　要：目的研究学龄期关节过度活动(generalised joint hypermobility,GJH)儿童的步态特征。方法应用三维运动捕捉系统及三维测力台采集56例GJH儿童及56例健康儿童步行时下肢关节的运动学和动力学数据,比较分析两组差异性。结果运动学参数:GJH儿童组的支撑相足内翻角度均值(P=0.000)、最大髋内收角度(P=0.002)及最大足廓清角度(P=0.004)减小,支撑相足偏角均值(P=0.000)、最大足内旋角度(P=0.000)及支撑相中期膝关节屈曲角度(P=0.032)增加。动力学参数:GJH儿童组的膝关节(P=0.005)、髋关节(P=0.000)的最大功率及支撑相踝关节最大内翻力矩(P=0.009)减小。时空参数:GJH儿童组步长(P=0.001)、步速(P=0.000)及步频(P=0.000)减小,支撑相百分比(P=0.000)及步宽(P=0.000)增加。结论GJH儿童的步行效率及平衡稳定性下降,踝关节存在力线排列异常问题,膝关节功能需要长期关注。Objective To investigate the gait characteristics of school-age children with generalised joint hypermobility(GJH).Methods The kinematic and kinetic data of lower extremity joints in 56 children with GJH and 56 healthy children were collected by 3D motion capture system and 3D force plates,and the differences between the two groups were compared and analyzed.Results Kinematics parameters:the mean ankle inversion angle(P=0.000),maximum hip adduction angle(P=0.002)and maximum foot clearance angle(P=0.004)in stance phase decreased in the GJH children group,while the mean foot progression angle(P=0.000),the maximum foot internal rotation angle(P=0.000)in stance phase,and the knee flexion angle(P=0.032)in the middle stance phase increased.Kinetics parameters:the maximum power of knee(P=0.005)and hip(P=0.000)joints and the maximum inversion moment of ankle joints(P=0.009)in stance phase decreased in GJH children group.Temporal and spatial parameters:the step length(P=0.001),walking velocity(P=0.000),and cadence(P=0.000)decreased in GJH children group,while the stance phase percentage(P=0.000),and step width(P=0.000)increased.Conclusions There is a decrease in walking efficiency and balance stability of children with GJH.The line alignment is abnormal in ankle joint.The knee function needs a long-term attention.
