With the eventual adoption of the GMFCS by researchers and rehabilitation professionals working with individuals with CP, other classification systems were developed. These include the Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), and the Eating and Drinking Ability Classification System (EDACS). The Communication Function Classification System (CFCS, www.cfcs.us) provides 5 levels (CFCS I, II, III, IV, V) to describe everyday communication performance. While originally developed for use with individuals with cerebral palsy, the CFCS is now being used to describe communication performance of individuals with any disability. The gross motor skills (e.g. sitting and walking) of children and young people with cerebral palsy can be categorised into 5 different levels using a tool called the Gross Motor Function Classification System (GMFCS). Manual Ability Classification System. The Manual Ability Classification System (MACS) can be used for children of different ages (4-18 years) but the interpretation of the levels needs to be related to the age of the child. Obviously, children handle different objects at age four years compared to adolescent age. PDF | The Manual Ability Classification System (MACS) has been developed to classify how children with cerebral palsy (CP) use their hands when handling objects in daily activities. The The Gross Motor Function Classification System (GMFCS) has become an important tool to describe motor function in children with Cerebral Palsy (CP). The Manual Ability Classification System (MACS) was developed recently as a corresponding classification of manual ability. The aim of this study was Comparison of purpose, age range, and ends of scoring continuum of three assessments us with children with cerebral palsy: -Gross Motor Function Classification System for Cerebral Palsy (GMFCS) -Manual Ability Classification System for Children with Cerebral Palsy (MACS) -Modified
