Background:

Crawling represents the first form of autonomous human locomotion. Much has been said about the implications that an adequate acquisition of crawling has on development in order to achieve independent gait in the short term and the child’s motor control in the long term. There are few studies related to crawling and its implications in children who were high biologic risk newborns. Therefore, we wanted to know the relation between crawling acquisition and independent gait in a population of children who were high risk at birth in our Pediatric Follow up clinic.

Material and Methods:

An observational, retrospective, and analytical study of a cohort of children who were high risk at birth, and attended our pediatric follow-up clinic was done. The period between crawling acquisition and independent gait was reviewed.

Results:

4 groups were integrated; normal crawling, borderline crawling, delayed crawling and null crawling. 558 infants were studied; the groups were integrated by: normal crawling 238 children; borderline crawling with 96 infants; delayed crawling with 207 children and null crawling with 17 children. By gender distribution, girls achieved better crawling. Weight and higher gestational age predominated in children with normal crawling. Crawlers had the best scores in the Bayley Scale. In children with normal crawling, independent gait was acquired within the normal period unlike the group with delay in crawling where independent gait was behind.

Conclusions:

In this study, we found a relation between the age of onset of crawling with the age of acquisition of the independent gait, with better skill in children who crawled.
