Spontaneous Kicking in Full-Term and Preterm Infants With and Without White Matter Disorder

Early damage to white matter of the brain may have developmental consequences for prematurely born infants including the coordination of leg movements Our perspective is that white matter damage inmates an ontogenetic course that may lead to movement dysfunction leading to disability In this study, spontaneous kicking in the human infant is a "window" for evaluating the potential consequences of perinatal brain damage for sensori-motor coordination We compare the tiara-limb coordination patients of 5-month-old premature infants wall white matte, damage (PTWMD) to a group of prematurely born infants without WMD (PT) and a group of full-term (FT) infants The PT group demonstrates advanced kicking patterns in comparison to both the PTWMD and FT groups The PTWMD group has less mature patients than the FT group on some, but not all measures. The movement challenge for PTWMD infants may be in the transition from spontaneous kicking to movements with the legs that require decouphng of intralimb Joints (C) 2010 Wiley Periodicals, Inc Dev Psychobiol 52 524-536, 2010
