观察了51名正常儿童的步态模式，包括时间、距离测量和地面反作用力。在两年的时间里，33名儿童在1、3、6、9或12个月时进行了一次重新测试，总共进行了84次步态观察。时间和距离测量以及脚-地反作用力测量取决于行走速度和儿童的年龄。身高随年龄增长是决定时间和距离测量随年龄变化的主要因素。平均步长是S身高的76%，步行速度为1.04m/S，无论儿童年龄。足底反作用力的3个分量(垂直方向、侧向和向前方向)在5岁以下随年龄变化，即使在归一化时也是如此。5岁以后，地面反作用力出现了成人型。当在3个月内重新测试时，4岁儿童的行走模式没有变化。句号。对于4岁的儿童，由于在3个月的生长过程中，测量结果发生了变化。重新测试的期限。在每隔3个月进行一次测试的4岁儿童中，也发现了类似的生长变化。分开。这可能在临床上对治疗效果的研究有用。
Gait patterns, including time and distance measurements and ground reaction forces, of 51 normal children were observed. Children (33) were retested once at 1, 3, 6, 9 or 12 mo., over a 2-yr period, for a total of 84 gait observations. Time and distance measurements and foot-ground reaction force measurements were dependent on walking speed and the age of the child. An increase in height with age was the major factor in determining the changes in time and distance measurements with age. Average stride length was 76% of the child''s height at a walking speed of 1.04 m/s regardless of the child''s age. The 3 components of foot-ground reaction force (vertical, lateral and forward directions) varied with age up to 5 yr even when normalized. After the age of 5 yr an adult pattern of ground reaction force emerged. Walking patterns of children who were > 4-yr-old did not vary when retested within a 3 mo. period. For children < 4-yr-old, measurements changed due to growth during the 3-mo. period to retesting. Similar changes due to growth were found in children > 4-yr-old who were tested at intervals > 3 mo. apart. This may be clinically useful in the study of the effects of treatment.
