Purposeused to assess pain in children

The FLACC scale or Face, Legs, Activity, Cry, Consolability 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.[citation needed]

Criteria[1] Score 0 Score 1 Score 2
Face No particular expression or smile Occasional grimace or frown, withdrawn, uninterested Frequent to constant quivering chin, clenched jaw
Legs Normal position or relaxed Uneasy, restless, tense Kicking, or legs drawn up
Activity Lying quietly, normal position, moves easily Squirming, shifting, back and forth, tense Arched, rigid or jerking
Cry No cry (awake or asleep) Moans or whimpers; occasional complaint Crying steadily, screams or sobs, frequent complaints
Consolability Content, relaxed 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.[2]
