  • Title: Reaching strategies of very preterm infants at 8 months corrected age.
    Author: Grönqvist H, Strand Brodd K, von Hofsten C.
    Journal: Exp Brain Res; 2011 Mar; 209(2):225-33. PubMed ID: 21267552.
    Abstract:
    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).
