Chronic noncancer pain in children and adolescents can be impairing and results in substantial health care costs. Intensive interdisciplinary pain treatment (IIPT), an inpatient or day hospital treatment delivered by a team of 3 or more health professionals, may be an effective intervention for these children and adolescents. Based on previous reviews and meta-analyses, we updated findings regarding the description of available treatments and estimated the effectiveness of IIPT, overcoming methodological shortcomings of previous work by requesting and analyzing individual participant data. ⋯ Regarding treatment effectiveness, IIPT may result in large improvements in the mean pain intensity ( g = -1.28), disability ( g = -1.91), and number of missed school days at the 12-month follow-up ( g = -0.99), as well as moderate improvements in anxiety ( g = -0.77) and depression ( g = -0.76). The certainty of the evidence, however, was graded from very low to low. We recommend that future researchers use more scientific rigor to increase the certainty of the evidence for IIPT and standardize treatment outcomes for children and adolescents with chronic pain.

Chronic pain remains a significant problem due to its prevalence, impact, and limited therapeutic options. Progress in addressing chronic pain is dependent on a better understanding of underlying mechanisms. Although the available evidence suggests that changes within the central nervous system contribute to the initiation and maintenance of chronic pain, it also suggests that the primary afferent plays a critical role in all phases of the manifestation of chronic pain in most of those who suffer. ⋯ A mechanism of sensitization that has received far less attention, however, is the local or axonal translation of these signaling molecules. A growing body of evidence indicates that this process not only is dynamically regulated but also contributes to the initiation and maintenance of chronic pain. Here, we review the biology of local translation in primary afferents and its relevance to pain pathobiology.
