The development of self-sitting ability in preterm infants seems to take place at lateronset compared with full-term infants. The question arises how segmental postural development correlate to changes in sitting milestone.

The correlations were analyzed using the Spearman's rank correlation coefficient. Results showed significantly high correlations between the segmental trunk control and sitting scales at 4 (r=0.658,p=0.000),5(r=0.805,p=0.000),6(r=0.761,p=0.000),and7(r=0.820,p=0.000) months corrected age.
