To evaluate the usefulness of Bayley scale of infant development, 2nd (BSID-II) in the diagnosis of cerebral palsy (CP) among the early childhood with delayed development.

We performed the BSID-II for children with delayed development who were diagnosed as CP or global developmental delay (GDD). The characteristics of mental developmental index (MDI) and psychomotor developmental index (PDI) of BSID-II were evaluated and sensitivity and specificity of BSID-II in the diagnosis of CP were studied.

While both MDI and PDI were decreased similarly in the GDD, PDI were significantly more decreased than MDI in the CP. The CP with hemiplegic pattern showed high MDI and PDI compared to those with the other patterns. When abnormal PDI defined as lower than 85 was used as a diagnostic criteria of CP, sensitivity and specificity were 0.88 and 0.41. When abnormal PDI defined as 13 and higher than MDI was used, sensitivity and specificity for the diagnosis of CP were 0.50 and 0.84.

The characteristic findings of BSID-II in the CP could be used as a supportive diagnostic measurement. We should interpret carefully in the children with hemiplegic pattern because they had a near normal MDI and higher PDI than functional status of hemiplegic limbs.
