Effects of Biopsychosocial Models Based on Pain or Functionality in the Treatment of Chronic Musculoskeletal Pain

The objective of this study is to evaluate whether a functionality-centered biopsychosocial model can improve clinical outcomes in the care of individuals with chronic musculoskeletal pain treated in a specialized healthcare service. The main questions it aims to answer are: Does the functionality-centered biopsychosocial model lead to a greater reduction in pain intensity compared to the pain-centered biopsychosocial model? Does the functionality-centered biopsychosocial model lead to greater improvement in functionality and performance of daily activities in individuals with chronic pain? Researchers will compare individuals treated using a functionality-centered biopsychosocial model with individuals treated using a pain-centered biopsychosocial model to determine whether the functionality-centered model results in better clinical outcomes and greater treatment adherence. Participants will: Attend weekly interdisciplinary appointments in a specialized chronic pain service for approximately 3 months. Undergo clinical assessments recorded in their medical records, including measures of pain intensity, pain interference, and functional status. Participate in interdisciplinary therapeutic interventions based on the biopsychosocial model, which may include pain neuroscience education, therapeutic exercises, behavioral strategies, and the establishment of functional goals.
