This research published by the Developmental Medicine and Child Neurology (DMCN) website, examines the link between Eating and Drinking Ability Classification System (EDACS) levels and dysphagia severity.

Cerebral palsy comprises a heterogeneous group of impairments that may also affect the oral motor functions necessary for eating, drinking, swallowing, and articulation. The daily feeding and swallowing skills in children with CP can be classified using the validated Eating and Drinking Ability Classification System (EDACS). EDACS categorizes children with CP aged 3 to 21 years into five levels, ranging from Level I: ‘eats and drinks safely and efficiently’ to Level V: ‘unable to eat and drink safely.’
