Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a promising, non-invasive neuromodulation technique due to its safety, ease of administration, and cost-effectiveness. Preliminary evidence suggests that taVNS exerts analgesic effects by activating afferent vagal fibers, which integrate signals in key central nodes such as the nucleus tractus solitarius (NTS). This process subsequently modulates pain-processing networks, neurotransmitter balance, inflammatory responses, and autonomic function.\n\nDespite its potential, the precise central neural mechanisms underlying taVNS-induced analgesia remain unclear, limiting the optimization of stimulation parameters (e.g., intensity, frequency, and target specificity) and the enhancement of long-term therapeutic outcomes. Previous studies have highlighted the role of taVNS in activating descending pain inhibitory pathways and modulating the limbic system, yet a comprehensive understanding of the causal neurophysiological dynamics is still lacking.\n\nThis study aims to investigate the analgesic efficacy of taVNS using a capsaicin-induced pain model. Furthermore, by employing Transcranial Magnetic Stimulation combined with Electroencephalography (TMS-EEG), we seek to elucidate the central neural mechanisms of taVNS. By integrating causal intervention with high-temporal resolution brain activity recording, this research will provide scientific insights into the modulation of pain-related pathways-such as descending inhibitory and cognitive-affective networks-ultimately facilitating the development of standardized, individualized, and precise clinical interventions for pain management.",[29,195,196,197,198,199,28],"Capsaicin-Induced Pain","Transcranial Magnetic Stimulation Repetitive","Electroencephalography","Vagus Nerve Stimulation","Neuromodulation","2026-07-19",{"date":202,"type":39},"2026-07-22",{"date":204,"type":22},"2026-07-10",{"date":206,"type":22},"2027-09-10",{"name":208,"class":45},"Second Affiliated Hospital, School of Medicine, Zhejiang University",{"id":210,"slug":211,"hasResults":12,"nctId":212,"briefTitle":213,"officialTitle":214,"acronym":4,"eligibilityCriteria":215,"healthyVolunteers":189,"sex":129,"minAge":18,"maxAge":216,"enrollmentInfo":217,"targetDuration":4,"studyType":23,"phases":219,"briefSummary":220,"conditions":221,"keywords":223,"overallStatus":35,"whyStopped":4,"lastUpdateSubmitDate":204,"lastUpdatePostDateStruct":228,"startDateStruct":230,"completionDateStruct":232,"leadSponsor":234,"locationsCount":46},"100481030","phase-4-ed90-of-epidural-bupivacaine-with-lidocaine-for-the-initiation-of-labor-analgesia-100481030","NCT05543694","ED90 of Epidural Bupivacaine With Lidocaine for the Initiation of Labor Analgesia","ED90 of Epidural Bupivacaine for the Initiation of Labor Analgesia: A Randomized Biased Coin Sequential Allocation Trial With a Lidocaine Test Dose","Inclusion Criteria:\n\n* Parturient with no major co-morbidities\n* Singleton, vertex gestation at term (37-42 weeks)\n* Less than or equal to 5 cm dilation\n* Desire to receive epidural labor analgesia\n* Numerical Rating Scale greater or equal to 5 (NRS 0-10, where 0 = no pain, and 10 = worst pain imaginable), at time of epidural labor analgesia request.\n\nExclusion Criteria:\n\n* Current or historical evidence of clinically significant disease or condition, including diseases of pregnancy (i.e preeclampsia, gestational diabetes)\n* Any contraindication to the administration of an epidural technique\n* History of hypersensitivity or idiosyncratic reaction to an amide local anesthetic agent\n* Current or historical evidence of a disease which may result in the risk of a cesarean delivery (i.e. history of uterine rupture).
