Perinatal Events and Motor Performance of Children Born With ELBW and Nondisabled

Abstract

To explore the relationship between perinatal variables and motor performance in children who were born with extremely low birth weight (ELBW) and were nondisabled at 1 and 4 years. Children without neurological or cognitive impairment (n = 48) born weighing less than 1000 g between 1992 and 1994 were assessed at 1 and 4 years corrected age using the Neurosensory Motor Developmental Assessment (NSMDA). Scores were used to categorize motor performance as normal or abnormal. Chronic lung disease (CLD) of prematurity, necrotizing enterocolitis (NEC), and patent ductus arteriosus were associated with NSMDA category at 1 year. Chronic lung disease, male gender, and NEC were associated with NSMDA category at 4 years. Multiple regression analyses revealed that CLD and NEC were independently associated with abnormal motor outcomes at 1 year. Early assessment and motor therapy is recommended for infants with CLD, because of its effect on motor performance in this otherwise healthy group of children born with ELBW.
