The Faces Pain Scale Revised (FPS-R) is a widely used, validated tool designed to help patients communicate their level of pain. The FPS-R is particularly useful for children and individuals with cognitive impairments who may have difficulty articulating their pain verbally. The scale consists of a series of faces, ranging from a happy face at one end (indicating "no pain") to a sad, crying face at the other end (indicating "very much pain").
