Improve daily functioning

What this outcome means

Activities of daily living are the everyday self-care tasks — dressing, bathing, eating, and moving around — that let you live independently. On DoseRank it maps to a defined health outcome built from human studies on validated ADL indices, functional-independence scores, and self-care task performance – data sourced from open sources and specialized resources. DoseRank is not medical advice.
