Abstract | PURPOSE: We aimed to translate the Early Clinical Assessment of Balance (ECAB) from English to Japanese and examine the content validity, inter-rater reliability, intra-rater reliability, construct validity, and minimal clinically important difference (MCID) for children with cerebral palsy (CP). METHODS: The ECAB was translated into Japanese per international standards. The study included 106 children with CP and, aged 1.5-12 years. The ECAB, the Gross Motor Function Classification System (GMFCS), and the Gross Motor Function Measure 66 Basal & Ceiling (GMFM-66-B&C) were measured. The content and construct validity were examined based on therapist feedback and correlations between the ECAB and GMFM-66-B&C. The inter-rater reliability and the intra-rater reliability were examined by the intra-class correlation coefficient (ICC). The MCID was calculated by the anchor-based method with the GMFM-66-B&C. RESULTS: High content validity (more than 80% agreement), inter-rater and intra-rater reliability (ICC = 0.99 & 0.99, respectively), and construct validity (r = 0.96) were demonstrated, with MCID values of 7.39, 5.32, and 6.88 observed for the GMFCS I/II, III, and IV/V, respectively. CONCLUSION: The Japanese version of the ECAB is a reliable and valid measure of balance ability in children with CP. Furthermore, the MCID of the ECAB was established, appears to be useful in helping to provide rehabilitation.Implications for RehabilitationThe Japanese version of the Early Clinical Assessment of Balance is easy, safe, and low-cost, and has high reliability and validity for assessing balance ability in children with cerebral palsy.The use of the Japanese version of the Early Clinical Assessment of Balance is beneficial for determining the therapeutic effect, appropriate treatment, and prediction of prognosis regarding balance ability in children with cerebral palsy.The minimal detectable change of the Japanese version of the ECAB suggest that a score exceeding 6 is a true change and the minimal clinically important difference of the Japanese version of the ECAB suggest that the scores exceeding 8, 6, and 7 for the GMFCS I/II, III, and IV/V, respectively, is a clinically useful change.
