Turkish version of gross motor function classification system-family report, determination of reliability and agreement between family and physical therapist in examining the gross motor function classification system level

The aim of the study was to create a Turkish version of the Gross Motor Function Classification System Family Report (GMFCS-FR) developed for children with Cerebral Palsy (CP), evaluate its reliability, and investigate its consistency between parents and physiotherapists. Within the study, it was planned to conduct the validity study of GMFCS-FR. Mothers, fathers and physiotherapists of 100 children with CP, aged 2-18 years, participated in the study. All children participating in the study were divided into five groups according to the appropriate GMFCS-FR as 2-4 years, 4-6 years, 6-12 years, 12-18 years and 12-18 years self report. The GMFCS levels were learned from physiotherapists and recorded. Mothers, fathers, and physiotherapists rated the children's motor skills using the appropriate GMFCS-FR. Mothers and fathers were asked to score the Pediatric Functional Independence Measure 2 (WeeFIM 2®) to determine the child's functional abilities. The test-retest reliability values of GMFCSFR were recorded as ICC= 0.990 , 0.991 , 0.985 , 0.987 , 0.989 for each group in mothers, and ICC= 0.961 , 1,000 , 0.989 , 0.986 , 1,000 in fathers. Interobserver reliability values were found to be ICC= 0.973 , 0.955 , 0.954 , 0.962 for mothers and physiotherapists, ICC= 0.929, 0.948 , 0.978 , 0.915 , 0.902 for fathers and physiotherapists. In the validity study, the relationship between GMFCS-FR classifications of mothers and fathers and WeeFIM 2® total scores was found to be r=0.847,0.840. The consistency of the mothers with the physiotherapists was recorded as : 0.738 , 0.676 , 0.806 , 0.530 , 0.718 and : 0.741 , 0.807 , 0.936 , 0.590 , 0.502 for the fathers. Recently, the activities of families in the rehabilitation program have gained importance. KMFSS-AR, which is a reliable, valid and consistent classification system in our study, will help families determine their children's motor performance and create a common goal with physiotherapists.
