Synopsis

Keywords: Brain Connectivity, Neuro, Pain

Persistent and chronic pain following acute musculoskeletal injury is a significant contributor to diminished quality of life. We correlated self-reported pain using the McGill Pain Questionnaire with resting-state brain network connectivity in patients with blunt chest trauma. Results suggest that both inferior parietal and insular cortex connectivity were positively correlated to greater self-reported pain and a region within the salient network showed a negative correlation. These results support the hypothesis that aberrant functioning of brain circuits that assign salience values to stimuli may contribute to pain perception. Understanding abnormal activity/connectivity may identify targets to prevent persistent and chronic pain.
