The Face, Legs, Activity, Cry, Consolability scale or FLACC scale is a measurement used to assess pain for children between the ages of 2 months and 7 years or individuals that are unable to communicate their pain. The scale is scored in a range of 0–10 with 0 representing no pain. The scale has five criteria, which are each assigned a score of 0, 1 or 2.
Occasional grimace or frown, withdrawn, uninterested
Frequent to constant quivering chin, clenched jaw
Normal position or relaxed
Uneasy, restless, tense
Kicking, or legs drawn up
Lying quietly, normal position, moves easily
Squirming, shifting, back and forth, tense
Arched, rigid or jerking
No cry (awake or asleep)
Moans or whimpers; occasional complaint
Crying steadily, screams or sobs, frequent complaints
Reassured by occasional touching, hugging or being talked to, distractible
Difficult to console or comfort
The FLACC scale has also been found to be accurate for use with adults in intensive-care units (ICU) who are unable to speak due to intubation. The FLACC scale offered the same evaluation of pain as did the Checklist of Nonverbal Pain Indicators (CNPI) scale which is used in ICUs.
