Summary Low back pain (LBP) is one of the most common reasons for all physician visits in the USA. The financial costs associated with the care of LBP are staggering. The treatments for chronic low back pain (cLBP) are far from satisfactory. Insurance claims data reveal that opioids are the most commonly prescribed class of drug for back pain, and more than half of regular opioid users reported using them for the treatment of back pain. Meanwhile, few new non-opioid and non-addictive pain medications have been developed in nearly five decades; thus, there is an urgent need for the development of new therapies for chronic low back pain. The vagus nerve (VN) consists of a complex network that regulates pain, mood, and the neuro-endocrine- immune axis. Studies suggest that auricular transcutaneous vagus nerve stimulation (tVNS), a non-invasive therapeutic method, can induce antinociception, which may affect peripheral and central nociception, inflammatory responses, autonomic activity, and pain-related behavior. Clinical studies and our pilot study have also shown that tVNS can significantly reduce symptoms of chronic pain and common comorbidities of chronic pain, such as depression and anxiety, thereby endorsing its potential for the treatment of cLBP. This proposal aims to investigate the treatment effect and underlying mechanism of tVNS on chronic low back pain. Patients with chronic low back pain will be randomized to either real or sham tVNS treatment for one month, with a three-month follow up. In addition to clinical outcome measurements, multiple brain imaging modalities, Quantitative Sensory Testing, and blood inflammation markers will be assessed. We believe that this study, if successful, will provide new treatment options for chronic low back pain, reduce the use of opioid analgesics in chronic pain management, and enhance our understanding of the underlying mechanism of tVNS treatment, as well as the pathophysiology and development of chronic pain.

概括 腰痛 (LBP) 是美国所有医生就诊的最常见原因之一。财务成本 与 LBP 的护理相关的数量是惊人的。慢性腰痛 (cLBP) 的治疗方法还很遥远 满意。保险理赔数据显示，阿片类药物是最常开具的药物类别 背痛，超过一半的阿片类药物经常使用者报告使用它们来治疗背痛。 与此同时，近五年来几乎没有开发出新的非阿片类药物和非成瘾性止痛药。 几十年；因此，迫切需要开发治疗慢性腰痛的新疗法。 迷走神经（VN）由一个复杂的网络组成，调节疼痛、情绪和神经内分泌 免疫轴。研究表明，耳廓经皮迷走神经刺激（tVNS）是一种非侵入性的方法。 治疗方法，可以诱导抗伤害感受，这可能会影响外周和中枢伤害感受， 炎症反应、自主活动和疼痛相关行为。临床研究和我们的试点研究 还表明，tVNS 可以显着减轻慢性疼痛和常见合并症的症状 慢性疼痛，如抑郁和焦虑，从而证实了其治疗 cLBP 的潜力。 本提案旨在探讨tVNS治疗慢性腰背痛的疗效及潜在机制 疼痛。患有慢性腰痛的患者将被随机分配接受真实或假 tVNS 治疗。 一个月，并进行三个月的随访。除了临床结果测量外，多脑成像 将评估模式、定量感官测试和血液炎症标记物。我们相信 这项研究如果成功，将为慢性腰痛提供新的治疗选择，减少阿片类药物的使用 镇痛药在慢性疼痛管理中的应用，并增强我们对 tVNS 潜在机制的理解 治疗，以及慢性疼痛的病理生理学和发展。
