ObjectiveThe purpose of this study was to develop a Japanese version of the Functional Mobility Scale (FMS), and examine the criterion validity and intra-rater reliability of the FMS in Japan.MethodsThe translation of the FMS was performed according to international standards for the translation of measurements. For criterion validity, 111 children with cerebral palsy (mean age; 12year 1mo±3year 7mo; range 5–18) were rated the Japanese version of the FMS and Gross Motor Function Classification System (GMFCS). For intra-rater reliability, the Japanese version of the FMS was rated twice by 24 parents of children with cerebral palsy by interview and/or telephone with a one- to two-week interval between assessments.ResultsThe criterion validity was confirmed with a strong correlation between GMFCS level and FMS scores (r²=−0.71 to −0.75). For intra-rater reliability, there was a substantial to excellent level of agreement (kappa=0.72–0.87).ConclusionThe study provides evidence of the criterion validity and intra-rater reliability of the Japanese version of the FMS as a measurement of mobility in children with cerebral palsy.
