Abstract

Chronic pain is one of the most disabling conditions globally, yet we are still missing a satisfying theoretical framework to guide research and clinical practice. This is highly relevant as research and practice are not taking place in a vacuum but are always shaped by a particular philosophy of pain, that is, a set of implicitly or explicitly prevailing assumptions about what chronic pain is and how it is to be addressed. In looking at recent history, we identify a promising trend from neuro-centrism to the application of the biopsychosocial model. Unfortunately, due to its limited theoretical foundation, the biopsychosocial model is too often implemented in a reductionist, fragmented, and linear manner. In particular, it remains too vague concerning the relationship between involved biological, psychological, and social processes. Sanneke de Haan prominently labeled this the integration problem. In this paper, we introduce five different facets of the integration problem that every philosophy of pain needs to address: (i) ontological, (ii) conceptual, (iii) explanatory, (iv) methodologicalMethodological, and (v) therapeutic. We develop an enactive theory of chronic pain and outline how far it provides solutions to these different integration challenges.
