[Pain mechanisms involved in chronic pelvi-perineal pain].

PAIN MECHANISMS INVOLVED IN CHRONIC PELVI-PERINEAL PAIN. Chronic pelvic and perineal pain, like other chronic pain, often is the result of specific organic lesion mechanisms, but can lead, via central and peripheral sensitization mechanisms, to dysfunctions that maintain the pain autonomously. To manage this type of pain in the most appropriate way, it is necessary to understand the mechanisms involved, and therefore the anatomical basis of the region, the neurophysiology of "normal" pain, and finally the various components involved when pain becomes chronic. The latter can become therapeutic levers.
