Résumé

Les principaux éléments sous-tendant les mécanismes de la douleur sont présentés. La douleur chronique résulte de processus de sensibilisation périphérique (inflammation, lésion de nerf) et centrale (neuroplasticité). D’un point de vue psycho-physiologique, la douleur résulte de l’expérience subjective d’une sensation émotive déplaisante, résultant de processus adaptatifs au sein de réseaux de neurones situés à différents niveaux du système nerveux central, dont les composantes peuvent augmenter ou diminuer en fonction des caractéristiques du stimulus, de l’état du sujet et du contexte dans lequel ce stimulus est appliqué.

Abstract

This paper describes the major factors underlying the physiology of pain. Chronic pain stems from various sensitization processes involving inflammation and nerve damage at the peripheral level and neuroplasticity at the central level. Pain results from an unpleasant emotional experience. Its various components, especially the emotional one, may increase or decrease in importance based on the different characteristics of the stimulus, the affective state of the patient, and the context in which this stimulus is acting.
