Background and aim: The aim of this study was to compare the gross motor development between Low Birth Weight (LBW) infants and Normal Birth Weight infants (NBW) at the age of 8-12 months by using the Peabody Developmental Motor Scale-2 (PDMS-2).
Material and Methods: This was a non experimental and cross sectional study which was conducted on 18 LBW infants with the history of being in Aliasghar hospital and 14 infants with the history of normal birth weight as a control group. Gathering the information was done by completing Questioner and then by using the Peabody Developmental Motor Scale-2 (PDMS-2). Finally the scores of the motor quotients were analyzed by independent T test statistical method.
Results: There was a significant difference (p= 0.002) between the mean gross motor quotient of LBW (90.83) and NBW ( 106.78).
Conclusion: This study showed that LBW infants attain low scores of gross motor skills in comparison with normal weight infants. It indicated that the LBW infants are more prone to motor development difficulties.
