A growing field of investigation into social justice cognitions and pain suggests perceived injustice has a negative impact on pain, but little is known about individual variation in the impact of a perceived injustice. One published study found that individuals with a strong rather than a weak just-world belief reported greater pain from the cold pressor task after experiencing a perceived injustice, but an overt measure of perceived unfairness is needed to investigate this relationship. ⋯ Recalled personal injustice unrelated to one's current pain experience had a negative impact on pain and anxiety associated with the cold pressor task. These findings indicate that intervention development should be cognizant of the role of everyday injustices and not just those related to pain, on the pain experience. WHAT DOES THIS STUDY ADD?: This study shows that, independent of just-world beliefs, perceived unfairness associated with a recalled injustice unrelated to pain has a negative impact on the experience of acute pain.

Chronic pain is often associated with sensorimotor dysfunction but little is known about the early impact of limb fracture on sensory and motor performance. This exploratory study sought to assess these changes in patients with recent wrist and ankle fractures. A secondary aim was to determine the incidence of Complex Regional Pain Syndrome (CRPS) and its clinical features. ⋯ Limb fracture is associated with changes in pain perceptions, motor planning, and disruption to body perception. Signs and symptoms of CRPS, ongoing pain and delayed recovery post-fracture are common. WHAT DOES THIS STUDY ADD?: In the immediate post-fracture period: Body perception disturbance is reported in the fractured limb. Imagined movements of the fractured limb are less vivid and associated with pain This study contributes to the incidence literature on CRPS.
