Special Issue Information

Dear Colleagues,

Chronic pain remains a major clinical and social challenge. Interventions addressing it should aim not only to reduce pain but to restore function and daily participation. We adopt a broad view of non-invasive neuromodulation: in addition to external techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), we include endogenous modulatory processes capable of reorganizing neural activity—for example, motor imagery, task-directed motor training, and therapeutic exercise—intentionally deployed as neuromodulatory strategies.

This Special Issue seeks contributions that link neurophysiological mechanisms with clinically meaningful and functional outcomes relevant to physical therapy and pain-centered practice. We invite clinical trials, translational studies, and systematic reviews that propose replicable, measurable interventions with demonstrable impact on activity and participation. Submissions that combine objective measures and patient-reported outcomes, and that integrate biopsychosocial and biobehavioral perspectives to support individualized treatment decisions, are especially welcome.

Our aim is to present a practical, evidence-based appraisal of current opportunities and limitations, and to promote interventions that genuinely improve function and quality of life for people living with chronic pain.

Abstract
Background: Chronic pain is a prevalent and disabling condition that affects physical health but also cognitive domains. Executive functions, including inhibitory control, cognitive flexibility, and working memory, essentials for self-regulation, treatment adherence, and coping with symptoms, are particularly compromised. Physiotherapy interventions, traditionally aimed [...] Read more.
Background: Chronic pain is a prevalent and disabling condition that affects physical health but also cognitive domains. Executive functions, including inhibitory control, cognitive flexibility, and working memory, essentials for self-regulation, treatment adherence, and coping with symptoms, are particularly compromised. Physiotherapy interventions, traditionally aimed at physical outcomes, may also influence executive functions; however, their impact remains unclear. Objective: This review aimed to synthesize current evidence regarding the effects of physiotherapy-related interventions on executive function in adults with chronic pain. Methods: The review followed the Cochrane Handbook and Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines, and the protocol was registered in PROSPERO (CRD42024611800). A comprehensive search was performed. Randomized controlled trials (RCTs) included adults with chronic pain (≥3 months) whose executive function outcomes were evaluated after physiotherapy-based interventions. Results: Out of 12,391 records, 10 randomized controlled trials were included. Populations primarily had fibromyalgia, chronic low back pain, and chronic musculoskeletal pain. Interventions encompassed transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (rTMS), neurofeedback, structured exercise, and multimodal physical-cognitive-mindfulness training. Intervention durations ranged from one session to 16 weeks. Executive function was assessed with diverse neuropsychological tests. tDCS improved attention, inhibitory control, cognitive flexibility, and working memory. Exercise interventions showed benefits in working memory and inhibitory control. Conclusions: Preliminary evidence suggests that physiotherapy interventions, particularly anodal tDCS and structured exercise, may improve executive functions in individuals with chronic pain. Future trials should incorporate long-term follow-up. Integrating cognitive targets into physiotherapy may enhance the multidimensional management of chronic pain. Full article

Background: Neuropathic pain represents a substantial global burden with limited effective therapeutic options. Pulsed Electromagnetic Field (PEMF) therapy has emerged as a potential non-invasive adjuvant, though clinical evidence remains inconsistent. This systematic review and meta-analysis evaluated PEMF efficacy and safety, specifically analyzing the influence of etiology and stimulation parameters. Methods: Following PRISMA 2020 guidelines (PROSPERO: CRD420251184151), five databases (Cochrane, PubMed, Scopus, Web of Science, and LILACS) were searched for Randomized Controlled Trials (RCTs) comparing PEMF versus sham. Risk of bias was assessed via Cochrane RoB 2, and heterogeneity was explored through detailed subgroup analyses. Results: Thirteen RCTs met the inclusion criteria (N = 688). While global analysis indicated a statistically significant pain reduction (SMD: −1.01; p = 0.03), it exhibited extreme statistical heterogeneity (I2 = 92.8%) and instability. After adjusting for missing studies using the Trim-and-Fill method, global significance disappeared. However, subgroup analysis resolved this inconsistency, revealing a massive, clinically meaningful effect in Spinal/Radicular pain (SMD: −2.35; 95% CI: −4.42 to −0.29), whereas Peripheral Neuropathy showed no significant reduction (SMD: −0.38; 95% CI: −0.86 to 0.10). Conclusions: The PEMF evidence base for neuropathic pain is currently highly fragmented. Extreme heterogeneity and publication bias render “one-size-fits-all” efficacy estimates invalid and potentially misleading. Instead, our data reveals a critical etiological divergence: PEMF appears highly effective for spinal/radicular pathology, likely due to the mechanical nature of the lesion, but demonstrates limited efficacy for diffuse peripheral neuropathy. Future research must abandon generic protocols in favor of etiology-specific trials, prioritizing high-frequency parameters and rigorous bias control. Full article
