Brief summary (from the registry)
Validation of a new clinical questionnaire, called 'MecPain', including 12 questions, aimed at better defining the pathophysiological mechanisms of a chronic pain condition. This questionnaire includes 8 components/sub-components, reflecting various aspects of the 3 main mechanisms of chronic pain: nociceptive, neuropathic, nociplastic. A series of 240 patients with well-characterized chronic pain syndrome (for more than 6 months) of the nociceptive, neuropathic or nociplastic type will be recruited (80 patients per type of pain). The patients will be interviewed by a pain specialist to complete the 12 questions of the questionnaire during a routine visit in a Pain Center (CHU Grenobles Alpes, Grenoble, France or CHU Henri Mondor, Creteil, France). The scoring obtained with the 'MecPain' questionnaire will be compared to the presence of neuropathic pain assessed by two previously validated questionnaires, the 'DN4' and the 'PainDETECT' questionnaires. The expected outcome is a validation of the 'MecPain' questionnaire to provide a better understanding of the pathophysiological mechanisms relating to the presence of a chronic pain syndrome in a given patient.
