目的：本研究的目的是评估步态速度与共峰矢状面参数之间关系的可预测性，以提供一组参考参数值。设计：收集64名健康成人的下肢生物力学数据，分别以其舒适的步行速度赤脚行走，然后以自己选择的快、慢和极慢的速度行走。绘制27个峰值关节参数值，并将其作为步态速度的函数进行回归。讨论：虽然大多数参数随步态速度的增加而变化，但总的来说，动力学参数比运动学参数具有更好的可预测性。大多数功率参数与步态速度呈二次关系。其中4个矩参数与步态速度呈线性关系，4个矩参数与步态速度呈二次关系。这些表和图中所示的关系可以作为“正常”步态参数值的参考。(C) 2002 Elsevier Science B.V.版权所有
Objective: The aim of this study is to assess the predictability of the relationships between gait speed and common peak sagittal plane parameters in order to provide a set of reference parameter values. Design: Lower extremity biomechanical data were collected in 64 healthy adults while walking barefoot at his/her comfortable walking speed, then at self-selected fast, slow and very slow speeds. Twenty seven peak joint parameter values were plotted and regressed as a function of gait speed. Discussion: While most parameters change with increasing gait speed, in general, the kinetic parameters had better predictability than the kinematic parameters. Most of the power parameters were found to have a quadratic relationship with gait speed. Of the moment parameters, four had a linear relationship with gait speed, while four had a quadratic one. These relationships shown in the tables and graphs here can be used as a reference for 'normal' gait parameter values. (C) 2002 Elsevier Science B.V. All rights reserved.
