title: A longitudinal study of children with Down syndrome who experienced early intervention programming.
abstract: OBJECTIVE
  The long-term motor, cognitive, and adaptive functioning of a sample of adolescents with Down syndrome who experienced an early intervention program was examined in this descriptive study.
  
  
  METHODS
  Ten children with Down syndrome (7 girls, 3 boys) who had participated in an early intervention program constituted the early intervention (EI) group. An age-matched group of children with Down syndrome (6 girls, 4 boys) who had not experienced an early intervention program served as a comparison group.
  
  
  METHODS
  The EI group's motor functioning was compared with that of a normative sample used in the development of the Bruininks-Oseretsky Test of Motor Proficiency. The cognitive and adaptive skills of the EI group were compared with those of the comparison group. The children were assessed using the Stanford-Binet Intelligence Scale, the Vineland Social Maturity Scale, and the Bruininks-Oseretsky Test of Motor Proficiency.
  
  
  RESULTS
  The EI group subjects fell below their chronological age levels in gross and fine motor skills; however, their mean gross motor skill levels exceeded their mean fine motor skill levels. The specific deficits in gross motor and fine motor skills, which were documented in a previous follow-up study on the same sample, continued to be areas of deficits (visual motor coordination, running speed, balance, and reaction time). The EI group subjects had significantly higher scores on measures of intellectual and adaptive functioning than did the children in the comparison group. The EI group subjects did not show the decline typically seen with age in adaptive functioning in individuals with Down syndrome.
  
  
  CONCLUSIONS
  Because of the design limitations, the differences between the groups should be interpreted with caution.
