Central mechanisms in the maintenance of chronic widespread noninflammatory muscle pain.

Desantana JM, Sluka KA

This article reviews the current and emerging literature about the pathophysiology and neurobiology of chronic widespread -musculoskeletal pain. Widespread musculoskeletal pain results in changes in the central nervous system in human subjects and animal models. These changes likely reflect alterations in supraspinal modulation of nociception, and include increases in excitatory and decreases in inhibitory modulation pathways. These alterations in excitation and inhibition likely drive changes observed in the spinal cord to result in central sensitization, and the consequent pain and hyperalgesia.
