The activities of daily living or ADLs represent, in the health sector, the activities necessary to take care of one's own body. These activities are necessary for survival, well-being and social participation. Basic activities of daily living include, for example: eating, bathing, going to the toilet, getting dressed, taking care of one's appearance. Although the activities of daily living can be defined, the way in which they are carried out can vary from one individual to another.
The ADL concept was invented in the 1950s by Dr. Sidney Katz and his team at Benjamin Rose Hospital in Cleveland, and has been revised and expanded by other researchers since then.
This scale makes it possible to quantify a person's autonomy. The lower the score, the more dependent the patient. It is necessary to make several evaluations spread over time.
