Early motor repertoire and neurodevelopment at 2 years in infants born extremely preterm or extremely-low-birthweight

Abstract

Aim: To determine the relationship between early motor repertoire and 2-year neurodevelopment in infants born extremely preterm (<28 weeks’ gestation) or extremely-low-birthweight (ELBW) (<1000g). Method: This was a geographical prospective cohort of 139 infants born extremely preterm/ELBW (mean gestational age 26.7 weeks, standard deviation [SD] 2.0, 68/139 [49%] male), with parent-recorded videos suitable for scoring the General Movements Assessment (GMA). Motor repertoire was assessed using the Motor Optimality Score-Revised (MOS-R), with and without the fidgety movement subsection, and the GMA alone at 12 to 13+6 weeks corrected age and 14 to 15+6 weeks corrected age. At 2 years correcte..
