"We have developed a new Eating and Drinking Ability Classification System (EDACS) for people with cerebral palsy. EDACS describes five distinct levels of ability using the key features of safety and efficiency (...). Our new Eating and Drinking Ability Classification System (EDACS) offers an alternative to subjective terms such as mild and moderate and severe which have no agreed definition. We developed EDACS by consulting with people with cerebral palsy, parents and experts around the world. EDACS has been tested to see how easy and reliable it is when used by speech and language therapists and parents."
