Randomized Controlled Trial
What Mediates Treatment Effects in a Pre-surgery Physiotherapy Treatment in Surgical Candidates with Degenerative Lumbar Spine Disorders? A Mediation and Conditional Process Analysis of the PREPARE Randomized Controlled Trial.
Treatment guidelines recommend targeting both physical and psychological factors in interventions for degenerative lumbar spine disorders. Studying the treatment mechanisms gives information on key factors explaining the outcome improvement that can refine treatments. This study explores treatment mediators in a physiotherapy treatment on disability, pain intensity, and health-related quality of life in surgical candidates with degenerative lumbar spine disorders compared with waiting-list controls. An additional aim was to evaluate patients' expectation as a moderator of treatment outcome. ⋯ Self-efficacy, fear-avoidance beliefs, physical activity level, and patients' treatment expectations were found to be important factors explaining treatment effects. Self-efficacy was the consistent mediator for effects of the presurgical physiotherapy on disability, back pain intensity, and health-related quality of life.

It is common for youth to engage in sport and unfortunately also common for chronic pain to emerge in childhood. The convergence of chronic pain and sports participation in youth has not been extensively studied. ⋯ Our study provides evidence that focusing on continued sports engagement in the context of chronic pain is associated with less pain-related distress and functional limitations when compared with those who discontinue sports involvement, thus may serve as a buffer in the context of chronic pain. The association of AI with pain-related distress suggests that there is emotional significance in the degree to which youth identify as an athlete. This may be beneficial to clinically assess in youth with chronic pain.

School-based educational programs have shown positive changes in health-related behaviors among adolescents. The aim of this study was to analyze the changes in pain-related knowledge among adolescents and in the use of positive responses to their peers' pain behaviors after watching a brief educational video. ⋯ The findings showed that a brief and inexpensive educational video-based intervention in schools helps to increase pain-related knowledge and change responses to students with chronic pain. This has the potential to prevent chronic pain and related disability among students, and decrease bullying-like behaviors toward students with chronic pain.

Chronic pain is theoretically conceptualized from a biopsychosocial perspective. However, research into chronic pain still tends to focus on isolated, biological, psychological, or social variables. Simultaneous examination of these variables in the prediction of outcomes is important because communalities between predictors exist. Examination of unique contributions might help guide research and interventions in a more effective way. ⋯ As expected, communalities between biopsychosocial variables exist, which resulted in a reduced number of unique contributions in multivariate analyses. Perceived injustice emerged as a unique contributor to variables, which points to this psychological construct as a potentially important therapeutic target in multidisciplinary treatment of pain.
