项目摘要

The ontogenetical development of human infant walking was kineticafly and kinematically studied. The study proposed empirical knowledge on the development of walking and shed light on the human acquisition of bipedalism.136 trials of 39 infants (21 males and 18 females) until 5 years of age were kinesiologically measured their independent walking. Longitudinal measurements were repeated on 15 infants (10 males and 5 fema1es) until 2 years of age. The number of longitudinal trials was 92 in independent walking and, in addition, 16 dependent walking. Data from two force plates, two VTR cameras, and a three-dimensional movement analyzing system were synchronized and recorded the movement and the force. The thickness of lower limb muscles was measured using the ultrasonic apparatus. Walking patterns of one-year-old infant were extracted on the time, posture, and foot force. Differences and similarities between the patterns in infants and adults were pointed out. Almost all of them are newly discovered in the present study. Two of them are summarized as follows :I) In many of walking parameters the infants do not develop evenly to the adults. Their development is very rapid in the earlier half of the one year of age.2) Duration of walking experience influences the ability of progressed walking. Infants with a longer experience of independent gait can walk more skillfully, when comparisons are made by controlling chronological age.

对人类婴儿行走的个体发育进行了运动学和运动学研究。这项研究提出了经验知识的发展，行走和阐明人类收购的bipedalis.136试验的39名婴儿（21名男性和18名女性），直到5岁的运动学测量他们的独立行走。对15名婴儿（10名男性和5名女性）重复纵向测量，直到2岁。纵向试验的数量是92独立行走，此外，16依赖性行走。来自两个测力板、两个VTR摄像机和三维运动分析系统的数据被同步并记录运动和力。用超声仪测量下肢肌肉厚度。从时间、姿势、脚力三个方面提取1岁婴儿的步行模式。指出了婴儿和成人的模式之间的差异和相似之处。它们几乎都是本研究中新发现的。其中两个问题概括如下：（1）在许多行走参数上，婴儿与成人的发展并不均衡。1岁前半期的发育非常迅速。2）行走经验的长短影响着前进行走的能力。当通过控制实际年龄进行比较时，具有较长独立步态经验的婴儿可以更熟练地行走。
