METHODS: Follow up study of very low birth weight infants (under 1500 g) admitted to the Neonatology Department of the Hospital 12 de Octubre in Spain between January 1991 and December 1996. At a corrected age of 2 years, 11.5\% (34 children) were diagnosed with cerebral palsy. Ages of attainment of sitting and walking were established by interview with the parents and were confirmed by examination. Age of attainment of sitting and type of cerebral palsy were investigated as possible predictors of ambulatory status. RESULTS: Sitting was attained by 73\% of the children. The probability of attainment of sitting at 9 months was 21\% and at 18 months it was 68\%. Only one child achieved sitting after 18 months. Fifty-three percent of the children became ambulatory. The probability of becoming ambulatory was 24\% at 18 months and 47\% at 30 months. If sitting was attained before 12 months of age the probability of becoming ambulatory was 47\% at 18 months and 76\% at 30 months. All children with spastic hemiplegia, 66\% of those with diplegia and only 8\% of those with quadriplegia became ambulatory. CONCLUSIONS: Sitting by the age of 12 months was directly related to achieving ambulation. Irrespective of the type of cerebral palsy, all children with hemiplegia and more than 60\% of those with diplegia ambulated while children with quadriplegia were much less likely to ambulate.
