描述了三名vervet婴儿大约在生命的前2个月的运动发展。在大约1个月大的时候，所有的动物都可以看到相当正常的行走运动（与成年动物相比），在2个月大的时候可以看到飞奔。早期运动步态模式通常异常，有时表现为跳跃型步态。观察到的大多数对称步态可归类为侧向序列。在2个月的时间里，动物的三尺和四尺支撑力下降，关节角位移模式改善。从婴儿最早的肢体运动开始，循环时间与四肢摆动和站立时间之间表现出显著的线性关系。我们认为运动控制机制可能在出生时相当成熟，但体重支持和姿势控制问题解释了这些婴儿最初表现出的运动困难。
The locomotor development of three vervet infants across approximately the first 2 months of life is described. Fairly normal‐looking walking movements (as compared to adults) were seen in all the animals by approximately 1 month of age and galloping was observed by 2 months. Early locomotor footfall patterns were often aberrant and bounding‐type gaits were sometimes exhibited. Most of the symmetrical gaits observed were classifiable as lateral sequence. Across the 2‐month period the animals showed decreased three‐ and four‐foot support and improvements in joint angular displacement patterns. From their earliest locomotor movements the infants showed significant linear relationship between both cycle duration and swing and stance durations of the limbs. We suggest that locomotor control mechanisms are probably fairly mature at birth but that weight support and postural control problems explain the initial locomotor difficulties exhibited by these infants.
