The Pediatric Balance Scale (PBS) is a modified Berg's Balance Scale developed as a balance measure for school-aged children with mild to moderate motor impairments. The purpose of this study was to determine the inter-examiner reliability of the Korean version of PBS when applied to children with developmental delays. In this study, PBS was administrated to a total of 79 children with developmental delays (17 with global developmental delay, 31 with cerebral palsy, and 31 with mental retardation) in the Seoul Community Rehabilitation Center. Two pediatric trained physical therapists with longer than 13 year of clinical experience scored the children's performance blind, while replaying videotaped data. The inter-examiner reliability was statistically determined by intraclass correlation coefficients (ICCs). The results of this study revealed that the Korean version of PBS seems to have high inter-examiner reliability when applied to children with movement disorders such as global developmental delay (ICC=.96) and cerebral palsy (ICC=.97); however, it has relatively lower inter-examiner reliability (ICC=.78) for children with developmental delay secondary to mental retardation. therefore, the results support that the Korean version of the PBS could be a useful clinical measurement to assess the balance skills for children with developmental delay who have an adequate level of cognition to enable them to fol1ow the verbal instructions to complete the test.
