The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is one of the most commonly and widely used behavioral observation pain scales.

Inter- and intrarater reliability coefficients were high (.92 and .87, respectively). Linear mixed modeling confirmed scale responsiveness (differences in difference between FLACC scores across phases for pa..
