Conservative, Non-pharmacological Interventions for Pain Management in Juvenile Idiopathic Arthritis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effectiveness of conservative, non-pharmacological interventions for chronic pain management in children and adolescents with juvenile idiopathic arthritis (JIA). A comprehensive search strategy was implemented across PubMed, PEDro, and Web of Science databases, utilizing predefined terms and strict inclusion and exclusion criteria. The initial search yielded 1,308 studies, which were subsequently narrowed to 65 relevant articles. Following a rigorous evaluation, 14 studies met the inclusion criteria for final review, with an average PEDro scale score of 6.1/10, indicating fair to good methodological quality. The included RCTs focused on various interventions, including physical exercise (five studies), hydrotherapy (three studies), orthoses (two studies), online cognitive behavior therapy for pain management (two studies), low-level laser therapy (one study), and video games (one study). A random-effects model meta-analysis was performed for interventions and outcome measures that were comparable across at least three RCTs. Physical exercise interventions met this criterion and were thus subjected to meta-analytic evaluation. The pooled analysis demonstrated a statistically significant beneficial effect of exercise interventions on chronic pain (mean difference (MD) = -1.37, 95% CI = -2.19 to -0.55, p < 0.01). Subgroup analyses further supported the efficacy of exercise compared to both other active interventions (MD = -1.37, 95% CI = -2.25 to -0.5, p < 0.01) and control conditions (MD = -1.69, 95% CI = -3.09 to -0.29, p = 0.02). These findings suggest that conservative, non-pharmacological interventions, particularly physical exercise, show promise as a component of a multidisciplinary pain management strategy for patients with JIA. While further high-quality research is needed to bolster the evidence base, our findings highlight the potential efficacy of integrating physical exercise interventions into comprehensive pain management strategies for this pediatric population.
