Latest conceptual, methodological, and clinical advances in chronic pain.

PURPOSE OF REVIEW: This review summarizes the most recent advances in the field of chronic pain, highlighting how the discipline is shifting from heterogeneous approaches toward more standardized, mechanistic, and personalized frameworks, both in clinical care and research.

RECENT FINDINGS: Recent progress in phenotyping and person-centered analytical approaches (like based on the ergodicity concept) have been proposed to reduce the structural heterogeneity of studies. At higher levels, the implementation of the WHO International Classification of Disease, 11th Revision and the Enhancing and Facilitating the TRUST worthiness initiative are reshaping methodological thinking in pain research. These initiatives emphasize the importance of universal and robust frameworks in pain research. Clinically, recent data are reinforcing the role of active strategies, digital therapeutics, and novel mechanistic approaches, including new pharmacological targets and less (or non-) invasive neuromodulation approaches. Issues related to problematic opioid use remain central, underscoring the need for better-integrated multimodal models.

SUMMARY: Robust, reproducible, and less variable pain research and clinical practices are increasing. Future perspectives rely on large-scale phenotyping, longitudinal data, the integration of digital technologies, and precision-medicine approaches applied to chronic pain.
