Coordination of low birthweight seven-year-olds.

The coordination and laterality of a group of 171 seven-year-old children, free from major disability, with a birthweight of 2,000 g or less, were examined and compared with those of normal birthweight peers. More low birthweight children were left-handed and of mixed or undetermined hand, foot and eye dominance. Left-handedness may adversely affect some areas of performance of normal birthweight but not of low birthweight children. Low birthweight children performed significantly less well in tests of both fine and gross motor coordination. Girls tended to perform better than boys in fine motor tests. In the low birthweight group there was a correlation between IQ and coordination.
