Background

Acute pain functions as a protective signal indicating potential or actual tissue damage, whereas chronic pain, persisting beyond the normal healing period, emerges as a convoluted clinical challenge. With the transition from acute to chronic pain, patients often endure significant functional impairment and emotional distress, resulting from neuroplastic changes in the peripheral and central nervous systems. These alterations heighten pain sensitivity and disrupt typical pain processing, contributing to the confluence of pain perceptions and pathways originating from various etiologies, including musculoskeletal injuries, inflammatory conditions, and nerve damage. During this evolution, frequently patients are affected by mixed pain. Mixed pain is a complex field of study within pain management, whose definition is still discussed. It is characterized by a blend of nociceptive, neuropathic, and sometimes nociplastic mechanisms. A multidisciplinary approach is essential to elucidate pathophysiological mechanisms and identify effective interventional, pharmacological, and rehabilitative strategies for managing mixed pain.

The primary objective of this Research Topic is to deepen our understanding of the complex interplay between nociceptive and neuropathic mechanisms, facilitating the development of personalized diagnostic tools and effective therapeutic strategies. Specifically, this research seeks to delineate the cellular and molecular pathways driving coexistence and mutual modulation of different pain components, including genetic, epigenetic, and neuroimmune factors. By innovating diagnostic and biomarker methods, such as neuroimaging and electrophysiological techniques, we aim to classify mixed pain subtypes, while advancing translational and preclinical research through the establishment of representative models. Furthermore, this Research Topic aspires to evaluate patient-centered multimodal therapies, emphasizing comprehensive clinical trials and prioritizing patient-reported outcomes.

To gather further insights into mixed pain and its multifaceted nature, we welcome articles addressing, but not limited to, the following themes:

• Uncovering cellular, molecular, genetic, or neuroimmune drivers of mixed-pain syndromes

• Validating biomarkers or imaging/electrophysiological signatures to distinguish mixed-pain subtypes

• Presenting robust preclinical models or translational studies of novel targets, such as pharmacological and neuromodulation approaches

• Reporting on clinical trials, observational studies, or case series evaluating combined therapeutic interventions

• Exploring patient-centered outcomes, digital health tools, and health-economic considerations

We invite manuscripts in the form of original articles, reviews, systematic reviews, meta-analysis, opinion articles, and case reports. Manuscripts should adhere to our journal's guidelines, be submitted in English, and observe ethical reporting standards.

Topic Editor Giacomo Farì received grants from Coloplast (SIUD National Congress, Bologna, June 2025), Menarini Group (Springer International Pain Academy 2025 and Roma Pain Days 2025), and Angelini Pharma (“Pain management in the general practitioners outpatient” project). The other Topic Editors declare no conflicts of interest.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
