Objective:To evaluate the integrated visual and auditory continuous performance test( IVA-CPT) and the ability of sensory integration in children, and then to investigate their correlation and the differences of ability of sensory integration in subtypes of ADHD children.Methods: 170 children were divided into four groups by the results of IVA-CPT, and then to assess the ability of sensory integration in each group of children.Results: In attention deficit subtype group, it showed negative correlation between visual response control quotient and the scores of noumenon feeling and body coordination. In hyperactive disorder-impulsion control disorder subtype group, it showed positive correlation between comprehensive scale response control quotient, visual response control quotient, comprehensive scale attention quotient, visual attention quotient and the scores of the development in learning ability. The scores of development in big muscles, neutralization felling and learning ability are lower than critical value in subtype of attention deficit and mixed type; The scores of development of learning ability are lower than critical value in hyperactive-impulsion disorder sutype, the scores of the sense of touch defence and mood are higher than critical value; the scores of others approached to critical value. Conclusion: The correlation between comprehansive quotient and the ability of sensory integration in different subtypes of ADHD is different according to the results of integrated visual and auditory continuous performance test. The ability of sensory integration is lower in every subtype of ADHD and they all have deficit problem of learning ability development; The imbalance of big muscles and neutralization felling in attention deficit subtype is significantly higher than hyperactive-impulsion subtype in children.
