Abstract
Some reflexions about chronic pain conceptualizations. The study and treatment of chronic pain implies a complex and multidiscipline approach. The analitic consideration of pain, taking into account the dimensions of pain and the triple response system, has been the chosen approach and the one that explains the actual state in the tackling of the problem. Nevertheless, it seems more reasonable from a clinical point of view to consider pain from a central, integrating perspective. Within this context, it is commented the theoretical trends in the definición of neuromatrix concept and the practical ones in the therapeutic considerations derived from that conceptualization.
