Abstract
【Purpose】 This study aimed to investigate the postnatal corrected age of hand grasping in
very low-birth weight（ VLBW） infants by birth weight.
【Methods】 The participants were 66 VLBW infants without major neurological handicaps.
The mean birth weight of the infant was 961 g. Hand grasping attainment and perinatal
factors of the infants were examined. The study infants were divided into Group A （birth
weight ＜1000 g） or B （1000 g ≦ birth weight ＜ 1500 g）. We analyzed the postnatal
corrected age of hand grasping between the two groups.
【Results】 In terms of hand grasping, the infants in Group A（ 90th percentile, 7.3 months）
were older than those in Group B（ 90th percentile, 6.8 months）.
【Conclusion】 Our results suggest that Infants with VLBW, particularly those with birth
weight ＜1000 g are associated with a risk of delayed attainment of upper limb function early
on. Therefore, early continuous assessment and developmental follow-up must be considered.
