{"title":"Uncertain Trajectories in Neuropathic Pain: Rethinking Treatment Response","authors":"Antonio Alcántara Montero","doi":"10.1002/ejp.70155","DOIUrl":"10.1002/ejp.70155","url":null,"abstract":"<p>Chronic neuropathic pain remains one of the most elusive clinical challenges. Despite advances in pharmacology, neuroscience, and phenotypic characterisation, patient trajectories continue to be marked by profound heterogeneity. Some individuals improve, others stagnate, and a few even deteriorate—without a clear ability to anticipate these outcomes. In a context where mechanistic classifications of pain are beginning to show their limitations, and where nociplasticity is emerging as an integrative paradigm, it becomes urgent to reconsider how we evaluate clinical evolution in patients with neuropathic pain. The recent study by Moisset et al. offers an original perspective on this challenge: rather than assessing treatment response as a static endpoint, it proposes viewing it as a trajectory—a curve unfolding over time. This longitudinal approach, grounded in group-based trajectory modelling, enables the identification of evolutionary patterns that elude conventional analyses. It is not merely a question of how much a patient improves, but how, when, and under what circumstances that improvement occurs (Moisset et al. <span>2025</span>).</p><p>The study is based on patients treated in multidisciplinary tertiary care centers, ensuring specialised assessment and structured follow-up. Through this approach, the authors identify three distinct clinical trajectories: one characterised by moderate pain that progressively decreases over time; another marked by persistent moderate pain with no significant change; and a third defined by severe pain that remains stable throughout the follow-up period. These trajectories are not interpreted as fixed response categories, but rather as dynamic expressions of the pain experience. Each poses different challenges in terms of monitoring, therapeutic adjustment, and clinical communication. This segmentation does not aim to label or oversimplify, but rather to offer a more sensitive lens through which to observe the evolution of pain. Nevertheless, it raises inevitable questions: how can these patterns be translated into concrete clinical decisions? Can we anticipate a patient's trajectory during consultation? And what tools do we need to do so without falling into reductionism?</p><p>Factors associated with more favourable outcomes—such as age, pain duration, baseline intensity, psychiatric comorbidities, and type of treatment—have been identified in previous studies, yet their predictive capacity remains limited. In practice, each patient's evolution challenges linear models and statistical expectations. Some improve unexpectedly, while others fail to respond despite all efforts. This compels us to ask whether we are truly measuring what matters. What variables are being left out of our algorithms? What role do social determinants, personal narratives, expectations, and the therapeutic relationship play?</p><p>Personalised medicine has become a therapeutic ideal, yet in the context of neuropathic pain, that id","PeriodicalId":12021,"journal":{"name":"European Journal of Pain","volume":"29 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejp.70155","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145312712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological studies are essential for understanding the scale of the problem and identifying approaches to management.

Emotional awareness was associated with higher pain intensity, and with more colouring for persistent pain.

Each participant performed three training sessions (t1, t2, t3) separated by 1 week, and education about pain and EIH after t2.

However, evidence regarding the effect of latissimus dorsi–thoracolumbar fascia (LD-TLF) complex stretching in patients with chronic low back pain (CLBP) remains limited. Therefore, this study aimed to investigate the effects of LD-TLF complex stretching on pain-related factors and disability in patients with CLBP.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Thirty patients with CLBP were randomly assigned to a study group (&lt;i&gt;n&lt;/i&gt; = 15; 7 men, 8 women) and a control group (&lt;i&gt;n&lt;/i&gt; = 15; 7 men, 8 women). The study group received 4 weeks of LD-TLF complex stretching in combination with conventional physiotherapy, while the control group received conventional physiotherapy only. Outcomes were assessed before and after the interventions, including primary measures of pain pressure thresholds (PPT) at thoracolumbar fascia levels (L1, L3 and 12th costa), and secondary measures included the Pain Sensitivity Questionnaire (PSQ), the effects of pain on daily activities measured by the Brief Pain Inventory (BPI), and disability assessed by the Oswestry Disability Questionnaire (ODQ).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Pre- and post-treatment PPTs, at the L1, L3 vertebrae and 12th costa levels, demonstrated significant differences between the study group and control groups. Post-treatment thresholds were significantly higher compared to pre-treatment thresholds (&lt;i&gt;p&lt;/i&gt; &lt; 0.001, ηp&lt;sup&gt;2&lt;/sup&gt; = 0.67; &lt;i&gt;p&lt;/i&gt; &lt; 0.001, ηp&lt;sup&gt;2&lt;/sup&gt; = 0.61; &lt;i&gt;p&lt;/i&gt; &lt; 0.001, ηp&lt;sup&gt;2&lt;/sup&gt; = 0.74). Additionally, significant improvements were found in PSC, BPI and ODQ scores in the study group compared to the control group (&lt;i&gt;p&lt;/i&gt; &lt; 0.05).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusion&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The results of this study suggest that stretching the LD-TLF complex may be a beneficial addition to the conventional physiotherapy approach for patients with CLBP. Specifically, LD-TLF complex stretching, when used in combination with conventional physiotherapy, appears to provide improved pain thresholds, decreased pain sensitivity and pain during activity, as well as reduced disability compared to conventional physiotherapy alone in patients with CLBP.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Significance Statement&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Chronic low back pain (CLBP) is a multifactorial condition, with the thoracolumbar fascia increasingly recognized as a potential contributing factor.
