Can a specific biobehavioral-based therapeutic education program lead to changes in pain perception and brain plasticity biomarkers in chronic pain patients? A study protocol for a randomized clinical trial

Abstract

Background Chronic pain conditions are complex multifactorial disorders with physical, psychological, and environmental factors contributing to their onset and persistence. Among these conditions, the role of brain-derived neurotrophic factor (BDNF) and the impact of a specific therapeutic education (TE) on pain management have emerged as important areas of research. Objective This study aims to investigate the effects of a specific type of therapeutic education on pain levels and BDNF concentrations. Methods In this single-blind, randomized clinical trial, patients will be randomly assigned to one of two groups: one will receive exercise with TE and the other without TE. Assessments will be made at baseline, mid-treatment, post-intervention, and at one and eight months. Outcomes This study will shed light on the effectiveness of a therapeutic education (TE) program in pain management. Additionally, it will provide information on its effects on BDNF levels, a biomarker of brain plasticity, as well as on various psychosocial variables that can influence pain experience. Conclusion By comprehensively addressing the need to quantify brain changes more precisely in individuals with chronic pain during interventions like TE and recognizing the importance of establishing a more structured and comprehensive protocol, this study lays a solid and replicable foundation for future evidence-based treatment developments.
