We analysed outcome domains and pain outcome measures in randomized controlled trials of interventions for postoperative pain management in children and adolescents and compared them to the core outcome set recommended by the Pediatric Initiative on Methods, Measurement and Pain Assessment in Clinical Trials (PedIMMPACT). ⋯ Recommended core outcomes have been insufficiently used in randomized controlled trials about postoperative pain in children, which hinders comparability of studies and makes synthesis of evidence difficult.

Psychological treatments are known to be effective for chronic pain, but little is understood about which patients are most likely to benefit from which ones. ⋯ Further research is needed to better understand who benefits most from psychological treatments for chronic pain. This study suggests that a flexible, multivariate and theoretical approach to identifying predictors of outcome may be valuable in furthering research in this area.

Reports of the overall chronic pain prevalence and its associated demographic characteristics among adolescents vary greatly across existing studies. Using internationally comparable data, this study investigates age, sex and country-level effects in the prevalence of chronic single-site and multi-site pain among adolescents during the last six months preceding the survey. ⋯ Chronic pain co-occurrence is common during adolescence across countries, the prevalence being among girls and in older age groups. Significant cross-country variations in the chronic pain prevalence and chronic pain patterns among adolescents exist. Significant country differences emerge for specific chronic pain patterns in association with adolescent demographics.

The prognosis of acute low back pain (LBP) is typically good; however, there is substantial variation in individual patient's outcomes. We recently developed a prediction model that was able to predict the likelihood of pain recovery in patients with acute LBP who continue to have pain approximately 1 week after initially seeking care. The aims of the current study were to (a) re-categorize the variables in the developmental dataset to be able to validate the model in the validation dataset; (b) refit the existing model in the developmental dataset; and (c) validate the model in the validation dataset. ⋯ A clinical prediction model based on five easily collected variables demonstrated reasonable external validity. The prediction model has the potential to inform patients and clinicians of the likely prognosis of individuals with acute LBP but requires impact studies to assess its clinical usefulness.

Actigraphy is a quantitative method for the investigation of human physical activity and is normally based on accelerometric and/or kinematic data. ⋯ People with chronic pain move differently. Movement quality is difficult to evaluate during daily activities, yet it may prove more informative than quantitative measurements. We proposed a new approach for computing movement complexity and found out that patients' movements get more stereotyped when higher spinal acceleration is required.
