The authors analyzed and compared the effect of additional weight on the spatiotemporal parameters of the kicking movement of late preterm and full-term infants. The experiment was divided into 4 conditions: training, baseline, weight, and postweight. In the W condition, a weight of one third the lower limb mass was added to the infant's ankle. During the baseline and postweight conditions, the ankle weight was removed. Late preterm infants do not differ from full-term infants in relation to spatiotemporal variables at 3 and 4 months. However, during the weight condition, the straightness index and the hip-ankle and knee-ankle correlations decreased in the preterm infants at both ages. In contrast, the straightness index increased in the postweight condition compared to the baseline values at both ages.
作者分析并比较了额外负重对晚期早产儿和足月儿踢腿运动时空参数的影响。实验分为4种情况：训练、基线、负重和负重后。在负重情况（W）下，将相当于下肢质量三分之一的重量加在婴儿脚踝上。在基线和负重后情况中，去除脚踝上的重量。晚期早产儿在3个月和4个月时的时空变量与足月儿并无差异。然而，在负重情况下，两个年龄段的早产儿的直线度指数以及髋-踝和膝-踝相关性均降低。相比之下，在负重后情况下，两个年龄段的直线度指数相较于基线值均有所增加。
