Influence of psychosocial factors in the experience of musculoskeletal pain: a literatura review

Abstract

Musculoskeletal pain is a health problem that affects approximately 33 % of the adult population, of which 56 % corresponds to elderly people and 35% to people of working age. Some epidemiological investigations have shown that there are certain groups of people within the population most likely to develop chronic musculoskeletal pain, these studies have allowed to identify different weaknesses and needs in the interventions of health professionals in this problem. The data have shown that the prevalence of pain is higher in women, smokers, with incomplete education, with psychological or social risk, in this way the evidence has removed attention to the nociception of body structures as the only causal factor of pain musculoskeletal. This has forced researchers to explore he infl uence of psychosocial factors in the experience of musculoskeletal pain, consider the integration of various factors and mechanisms to explain the development of the painful experience. The objective of this review is to describe the psychosocial factors that influence the experience of musculoskeletal pain in order to relate them to contemporary neuroscientific models.
