FLACC stands for face, legs, activity, crying and consolability. It is an observer rated pain scale, performed by a healthcare practitioner such as a doctor or a nurse. The FLACC pain scale was designed for children between the ages of 2 and 7. However, some practitioners in adult settings may use the FLACC pain scale for people who are unable to communicate their pain. FLACC provides a pain assessment scale between 0 and 10.
