Stability of caregiver-reported manual ability and gross motor function classifications of cerebral palsy.Inter-rater agreement of the Arabic Gross Motor Classification System Expanded & Revised in children with cerebral palsy in Jordan.A comparative assessment of motor function using the expanded and revised gross motor function classification system and the manual ability classification system in the same children with cerebral palsy in Shika, Zaria, Northwestern Nigeria.A population-based study of 359 children. Association between gross motor function (GMFCS) and manual ability (MACS) in children with cerebral palsy.Functional profiles of children with cerebral palsy in Jordan based on the association between gross motor function and manual ability.Understanding participation of children with cerebral palsy in family and recreational activities.
INTERPRETATION: The findings support repeated classification of children over time. For children 4 years of age or older, level of function did not change for 72.3% on the GMFCS, 49.1% on the MACS, and 55% on the CFCS. For children younger than 4 years of age, level of function did not change for 58.2% on the GMFCS, 30.3% on the MACS, and 39.3% on the CFCS. RESULTS: Kappa coefficients varied from 0.76 to 0.88 for the GMFCS, 0.59 to 0.73 for the MACS, and 0.57 to 0.77 for the CFCS. A linearly weighted kappa coefficient of ≥0.75 was the criterion for stability. Consensus between parents and therapists on level of function was ≥92% for the GMFCS, MACS, and CFCS. METHOD: Participants were 664 children with cerebral palsy (CP), 18 months to 12 years of age, one of their parents, and 90 therapists. N2 - AIM: To determine the stability of the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS) over 1-year and 2-year intervals using a process for consensus classification between parents and therapists. JF - Developmental medicine and child neurology T1 - Stability of the Gross Motor Function Classification System, Manual Ability Classification System, and Communication Function Classification System.
