Neuropathic Pain

The primary objective is to demonstrate the analgesic effect at day 60 of 8% capsaicin patch (Qutenza) for the treatment of patients with coccygodyinia.

This cross-sectional observational study aims to evaluate neuropathic pain severity in patients with lumbar spinal stenosis (LSS) and to investigate its association with radiological findings. Neuropathic pain will be evaluated using the Neuropathic Pain Symptom Inventory (NPSI). Pain intensity, neuropathic pain characteristics, functional status, walking capacity, and psychological symptoms will also be assessed. The relationships between NPSI scores and clinical, functional, psychological, and radiological parameters will be investigated.

SERENITY is a remote observational study designed to characterize inter-individual differences in chronic pain among adults with chronic low back pain and adults with spinal cord injury-related neuropathic pain. Participants will complete baseline assessments and intensive longitudinal data collection using ecological momentary assessment surveys, brief cognitive tests, and passive Fitbit data collection. Ecological momentary assessment surveys will be completed 4 times per day for at least 3 weeks and will assess pain interference, pain intensity, stress, affect, sleep, body and mind awareness, agency, medication use, manual therapy frequency, and related factors. The study will use Bayesian hierarchical modeling, clustering analyses, and causal discovery approaches to identify person-specific and group-level factors associated with pain interference.

This study will comprehensively investigate the insula as a brain target for neuromodulation to treat chronic neuropathic pain.

The purpose of this study is to determine if playing a virtual reality walking game can help improve neuropathic pain in adults with incomplete spinal cord injury.

The goal of this clinical trial is to learn whether virtual reality (VR)-based hypnotherapy, added to conventional physiotherapy, improves pain, sleep, mood, and quality of life in adults with chronic spinal cord injury. The main questions it aims to answer are: * Does VR-based hypnotherapy added to physiotherapy reduce pain intensity more than physiotherapy alone? * Does it improve neuropathic pain, sleep quality, anxiety and depression, spasticity, and quality of life? Researchers will compare participants who receive VR-based hypnotherapy in addition to physiotherapy with participants who receive physiotherapy alone. Participants will: * Receive a standard physiotherapy and rehabilitation program 5 days a week for 2 weeks (10 sessions). * If assigned to the VR group, also receive an approximately 20-minute VR-based hypnotherapy session after each physiotherapy session, using a VR headset and headphones. * Complete assessments at the start of the study, at the end of the 2-week treatment period, and 2 weeks after treatment ends.

Chronic neuropathic lumbar pain is among one of the most widespread complaints of patients.Many approaches have been attempted to target chronic pain, with varying efficacy and risks. Transgrade (TG) epidural injection is a new technique using a Racz- Coudé needle for epidural access at a "transgrade" angle without requiring any specialized hardware or accessories. Interlaminar (IL) epidural steroid injection (ESI) is one of the procedures that involves the delivery of injectate to the epidural space through directing a needle between the laminae of two adjacent vertebrae.

Traumatic peripheral nerve injury is a common cause of chronic neuropathic pain, muscle weakness, and functional limitation, particularly in young and active individuals. Current conservative and pharmacological treatments often provide incomplete relief or carry side effects. High-intensity peripheral magnetic stimulation (PMS) is a non-invasive method that may help reduce neuropathic pain and support motor recovery, but evidence in traumatic nerve injury is limited. This randomized, double-blind, sham-controlled trial aims to evaluate whether high-intensity PMS, added to a standardized therapeutic exercise program, improves pain, function, quality of life, and electrophysiological measures in adults with traumatic peripheral nerve injury. Participants will be randomly assigned to receive either active PMS or sham PMS, in addition to the same exercise program. Outcomes will be assessed at baseline, 4 weeks, and 8 weeks.

Spasticity and neuropathic pain are frequent and disabling symptoms of multiple sclerosis. Intermittent theta-burst stimulation (iTBS) is a non-invasive neuromodulation technique that may modulate cortical and corticospinal excitability and thereby improve motor symptoms and pain. This randomized, parallel-group, sham-controlled, assessor-blinded study will evaluate the clinical efficacy of active iTBS compared with sham stimulation in adults with multiple sclerosis and clinically significant lower-limb spasticity and pain. Participants will receive five stimulation sessions over one week. Spasticity, pain, patient-reported outcomes, and the electrophysiological H/M ratio will be assessed at baseline and at Weeks 2 and 4 after the intervention.

The overall objective of this study is to test an intervention of green tea extract (GTE) to mitigate neuropathic pain in patients, specifically cancer survivors, receiving supportive palliative care. The central hypothesis is that daily, oral, encapsulated GTE will mitigate neuropathic pain, as longitudinally measured by the validated Douleur Neuropathique 4 (DN4) and blood protein biomarkers reported to be linked to the development and/or chronicity of neuropathic pain.

This study is testing a new program called Empowered Relief for Caregivers (ER-CY), designed to support caregivers of children and teens who live with chronic pain. ER-CY is a single two-hour class delivered online. It teaches skills for managing the stress of caring for a child in pain and for responding to a child's pain in helpful ways. Up to 80 caregivers of youth with chronic pain will take part in one ER-CY class and then complete surveys and a short interview over the following three months. The researchers want to learn two things: whether caregivers are willing and able to take part and find the program helpful and satisfying, and whether the program lowers caregiver distress and improves their child's day-to-day functioning. What is learned will help guide future programs and care for youth with chronic pain and their families.

This is a study evaluating the Scrambler Therapy device as a non-invasive treatment for neuropathic pain in pediatric oncology patients with metastatic bone disease. The primary goal is to assess changes in pain intensity and medication use, aiming to improve quality of life and reduce reliance on systemic pain medications.

This study employs temporal interference stimulation (tTIS) to investigate the analgesic effects of tTIS on neuropathic pain and monitor changes in neural plasticity, and explore the dynamic relationship between analgesic efficacy and neural plasticity, thereby providing new strategies for the treatment of neuropathic pain.

The pbjective of this study is to assess the impact of a multi-strain bacteria probiotic OXXYSLAB® on the reduction of oxaliplatin-induced peripheral neuropathy in patients with stage III colon cancer receiving FOLFOX or XELOX regimen in adjuvant treatment, assessed using the oxaliplatin-specific scale of Levi.

The goal of this clinical trial is to evaluate safety and tolerability of multiple oral doses of EC5026 in male and female patients with neuropathic pain due to traumatic or non-traumatic (degenerative) spinal cord injury. The main question it aims to answer is whether EC5026 is safe and well tolerated in SCI patients with neuropathic pain. In addition, this trial will also study the effects of EC5026 on pain. Researchers will compare EC5026 to placebo. Participants will be asked to: * Take EC5026 or placebo in a masked fashion, once daily, for 14 consecutive days. * Undergo physical exams, vital signs assessments, ECGs, and blood draws * Complete assessments of pain, sleep, functional status, and perception of change

PREDICT-DOLOR VE is a structured clinical triage protocol for chronic pain that uses five internationally validated pain assessment instruments to help healthcare providers determine the appropriate level of care for patients with chronic pain. The tool operates on a free mobile-friendly platform and generates a four-level recommendation: primary care management, referral to physiatry or neurology, priority specialist evaluation, or evaluation for neurosurgical intervention. This study will validate the diagnostic accuracy of the PREDICT-DOLOR VE algorithm by comparing its recommendations with the independent assessment of a panel of three specialists in adult patients with chronic pain (lasting 3 months or longer) across three referral centers in Venezuela. The study aims to determine whether this structured, low-cost approach can help connect patients with the right type of care more quickly and consistently.

Osteoporotic vertebral fractures may lead to chronic pain with a neuropathic component, which is often underdiagnosed and undertreated in older adults. This proof-of-concept randomized controlled trial aims to evaluate whether early application of a 5% lidocaine plaster can prevent the development of neuropathic pain following an osteoporotic vertebral fracture. Participants will be randomized in a 2:1 ratio to receive either a daily 5% lidocaine plaster plus standard care or standard care alone for 2 months. The primary outcome is the proportion of participants who develop neuropathic pain at 2 months, assessed using the PainDETECT questionnaire.

Chronic post-surgical pain (CPSP) remains a common complication after thoracic surgery and may significantly impair patients' quality of life. Although the widespread adoption of video-assisted thoracic surgery (VATS) has reduced surgical trauma and improved postoperative recovery, a substantial proportion of patients still develop persistent pain. The EVATHO study is a multicenter prospective observational cohort designed to determine the prevalence of CPSP three months after VATS and to identify perioperative factors associated with its development. Adult patients undergoing thoracic surgery by VATS at Montpellier and Nice University Hospitals will be prospectively enrolled. Pain intensity, neuropathic pain characteristics, anxiety, depression, quality of life, and analgesic consumption will be assessed using validated questionnaires during the perioperative period and at 1 and 3 months after surgery. The results of this study may help identify patients at increased risk of CPSP and improve perioperative pain management strategies following thoracic surgery.

This prospective observational study aims to evaluate the relationship between hematological inflammatory indices and clinical treatment response in patients with neuropathic pain undergoing sympathetic nerve block procedures as part of routine clinical care. Hematological parameters including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), aggregate index of systemic inflammation (AISI), and red cell distribution width (RDW) will be evaluated before and after treatment. The association between changes in these indices and pain outcomes will be analyzed.

Cortical stimulation has been used since 1991 to treat neuropathic pain. However, the underlying mechanisms are still incompletely understood and under-studied. In this protocol, the investigators aim to study the myeloarchitectonic and functional characteristics of areas activated by cortical epidural electrodes and to determine their relation to therapy response in chronic neuropathic refractory pain patients.

The aim of our study is to investigate the effect of different protocols of high-frequency Repetitive Transcranial Magnetic Stimulation (rTMS) therapy added to the rehabilitation program on neuropathic pain,depression, quality of life and quality of sleep compared to each other and placebo group in participants with spinal cord injury.
