The Manual Ability Classification System (MACS) is a medical classification system used to describe how children aged from 4 to 18 years old with cerebral palsy use their hands with objects during activities of daily living, with a focus on the use of both hands together.
MACS levels are stable over time and so they can be used as part of a prognosis for individuals.
[6] Alternative classification systems used for children with CP include: ABILHAND, AHA, CHEQ, CPQOL, House, MUUL, PedsQLCP, and SHUEE.
[7] A version of the test for children under the age of four years old, the Mini-MACS, was developed in 2016.
It has similar tiers to the MACS, with descriptions that are more relevant for the toddler age group, and has good inter-rater reliability.
