本研究调查了不同高度的障碍物对 15 名健康受试者运动的影响。研究了以下参数：（1）脚趾离地和脚跟接触期间脚趾和脚跟标记分别距障碍物的距离，（2）脚趾和脚跟标记的最小间隙距离，以及（3）臀部、膝盖的角位移和速度。和脚踝。结果显示，随着障碍物高度的增加，关节角度运动学和间隙距离存在显着差异。运动学和距离差异表现出强烈的线性和非线性趋势。脚趾离地距离和脚跟接触距离并没有随着障碍物高度的变化而发生显着变化。 (C) 1999 Elsevier Science B.V. 保留所有权利。
This study investigated the effect of obstacles of different heights on the locomotion of 15 healthy subjects. The following parameters were studied: (1) the distance of the toe and heel markers from the obstacle during toe-off and heel contact, respectively, (2) the minimum clearance distance of the toe and heel markers, and (3) the angular displacements and velocities of the hip, knee. and ankle. Results show significant differences in joint angular kinematics and clearance distances as obstacle height increased. The kinematic and distance differences exhibited both strong linear and non-linear trends. Toe-off distance and heel contact distance did not change significantly with changes in obstacle height.
