ABSTRACT

Objective : This study is to find out the scale to screen the Cerebral palsy (CP) out of developmental delayed infants. And we evaluate the usefulness of Capute Scale and Bayley Scales of Infant Development, 2nd (BSID-II). Therefore it would be help to diagnosis of CP in early infant and build up the rehabilitation strategy and intervention strategy.Methods : Subjects were 250 developmental delayed infants visiting university hospital in Cheonan-city, aged under 48 months. The tests were examined from Aug. 2002 to Dec. 2005. We examined the subject Capute Scale composed of Clinical Linguistic and Auditory Milestone Scale (CLAMS), Cognitive Adaptive Test (CAT), Mixed CAT/CLAMS, and BSID-II composed of Mental Development Index (MDI), Psychomotor Development Index (PDI), Behavior Rating Scale (BRS), and the difference between MDI and PDI.Results : 1. Eighty-six CP infants (34.4%) were screened and 164 global developmental delayed infants (GDD) (65.6%) within the 250 developmental delayed infants.2. There were 41.7% CP under the 37 weeks compared 26.8% CP above 37 weeks of gestational age.3. When comparing the average of difference between the CP and the GDD, CP are significantly lower than the GDD in CAT and CAT/CLAMS. CP are significantly lower than the GDD in the PDI and BRS in the BSID-II. CP are significantly higher than the difference between MDI and PDI.4. When the cut off score is under 80 of the indices of Capute Scale, there were significantly high distributed CP in the indices of CAT and CAT/CLAMS (respectively, p<0.001, p<0.01). Under the 85, 25, and above 13 in PDI, BRS, the difference between MDI and PDI of BSID-II respectively, there were significantly high distributed CP (respectively, p<0.001, p<0.05, p<0.001).5. The indices of Capute Scale and BSID-II are significantly correlated (respectively, p<0.001).6. When the predicted model is made by logistic multiple regression, the most effective factor is PDI, the next is gestational age and the difference between MDI and PDI. And the power of explanation of this model is 25%.Conclusion : The most effective scale to screening of CP is PDI of BSID-II in the developmental delayed infants. And difference between MDI and PDI is considered as useful to screening of CP in the developmental delayed infants.
