Objective: The aim of this study was to examine the reliability and validity of the Gross Motor Function Measure (GMFM) as gross motor function measure for Fukuyama Congenital Muscular Dystrophy (FCMD) patients.
Method: Subjects were 38 FCMD patients (20 males and 18 females), and the average age was 10.5 years (3-20 years old). One physical therapist evaluated the motor function of all patients by using the GMFM, and at the same time, confirmed the motor function level in Fukuyama Congenital Muscular Dystrophy (motor function level). To investigate the reliability and validity, and to obtain measurement of the internal consistency at Cronbach’sα, the test retest method was utilized to calculate standard error of measurement (SEM) of interclass correlation coefficient (ICC). The validity examined the correlation between of GMFM and motor function level and the correlation of age and exercise capability in every aspect in coefficient correlation of Spearman.
Results: All aspects were 0.96 or more in the ICC, and Cronbach’sα was 0.96, and SEM were 2.1–4.3%. GMFM is correlated with all motor function level, 0.90 or more. From a scatter diagram, the relations of age with every aspect were able to be confirmed, the correlation was 0.70–0.75.
Conclusion: GMFM high reliability and validity as gross motor ability evaluation scale of FCMD could be confirmed.
