Psychometric properties of the Fine Motor Function Measure Scale for children with cerebral palsy / 中华物理医学与康复杂志

ABSTRACT

Objective To analyze the psychometric properties of the Fine Motor Function Measure Scale (FMFM) with cerebral palsied children less than 3 years old. Methods Three hundred and seventy-five children less than 3 years old with cerebral palsy were involved. The test-retest reliability, inter-tester reliability, correlation validity and structural validity of the FMFM were analyzed, as well as the responsiveness. Results The test-retest reliability (ICC = 0. 983 3 ) and the inter-tester reliability (ICC = 0. 992 4) of the FMFM were satisfactory. The correlation index between the raw FMFM scores and scores on the Peabody Developmental Motor Scale——Fine Motor was 0.919 9. The FMFM could clearly distinguish differences in fine motor function between the affected side and the intact side in children with hemiplegia. The differences in fine motor function between children with diplegia and quadriplegia could also be distinguished by the FMFM. The effect size of this scale was also good. Conclusion The reliability, validity and responsiveness of the FMFM were satisfying. The fine motor functioning of children with cerebral palsy could be effectively measured using the FMFM scale.
