研究了一组极早产儿和一组足月婴儿在伸手取移动物体时的伸手策略和运动学。8个月大（矫正年龄）的婴儿在垂直平面上以半圆形路径移动小玩具。使用3D运动分析系统测量目标和婴儿的手的轨迹。在婴儿遇到目标的频率上没有发现差异。然而，早产儿组比足月组更频繁地使用双手策略，并且有更多弯曲的到达路径。这些结果表明，非常早产的婴儿在捕捉移动物体方面与健康的足月婴儿一样成功，但与8个月（矫正年龄）的足月婴儿相比，他们的到达策略效率较低。
Reaching strategies and kinematics for a group of very preterm infants were investigated and compared with a group of full-term infants when reaching for a moving object. Eight-month-old (corrected-age) infants were presented with small toys moving on a semicircular path in the vertical plane. The trajectories of the target and the hands of the infants were measured using a 3D motion analysis system. No differences were found in how often the infants encountered the target. The very preterm group, however, used bimanual strategies more often and had more curved reaching paths than the full-term group. These results suggest that very preterm infants are equally successful as healthy full-term infants in catching a moving object but their reaching strategies are less efficient compared with full-term infants at 8 months (corrected age).
