Pain drawing characteristics and risk for sleep breathing disorders in an orofacial pain service

Introduction: Subjects living with chronic pain are at risk for developing sleep breathing disorders (SBD). Altered sleep modifies the perception and reported intensity of pain. Many tools exist to evaluate pain, including validated scales and pain drawings. Pain drawings are associated to psychological profiles and prognostic variables in published studies on nociceptive lower back or peripheral pain. The utility of pain drawings in the orofacial pain area may be associated to disability, pain intensity, and risk for altered sleep.
