Characteristics of chronic non-specific musculoskeletal pain in children and adolescents attending a rheumatology outpatients clinic: a cross-sectional study

Background: Chronic non-specific musculoskeletal pain (CNSMSP) may develop in childhood and adolescence, leading to disability and reduced quality of life that continues into adulthood. The purpose of the study was to build a biopsychosocial profile of children and adolescents with CNSMSP. Methods: CNSMSP subjects (n = 30, 18 females, age 7-18) were compared with age matched pain free controls across a number of biopsychosocial domains. Results: In the psychosocial domain CNSMSP subjects had increased levels of anxiety and depression, and had more somatic pain complaints. In the lifestyle domain CNSMSP subjects had lower physical activity levels, but no difference in television or computer use compared to pain free subjects. Physically, CNSMSP subjects tended to sit with a more slumped spinal posture, had reduced back muscle endurance, increased presence of joint hypermobility and poorer gross motor skills. Conclusion: These findings support the notion that CNSMSP is a multidimensional biopsychosocial disorder. Further research is needed to increase understanding of how the psychosocial, lifestyle and physical factors develop and interact in CNSMSP

An ecological and lifespan approach of social influences on childhood pain experiences

Pediatric pain is a common experience that not only impacts the child but also their social environment (e.g., parents, peers, school functioning). Several models have been formulated to gain a better understanding of the social context interwoven with pediatric pain, with the Social Communications Model the most well-known and comprehensive model. More recent model development has focused on providing an explanation of specific pathways to adaptive or maladaptive pain-related functioning in children (e.g., Interpersonal Fear-Avoidance Model, Ecological Resilience-Risk Model). The purpose of the current chapter is to provide an overview of both the Interpersonal Fear-Avoidance Model and the Ecological Resilience-Risk Model, followed by a critical evaluation of their merit in furthering our understanding of pediatric chronic pain across development and within the broader social context (e.g., peers and school environment). The chapter will conclude with directions for future research, model development and clinical practice
