研究目的:

本研究旨在通过前瞻性随机对照试验,系统评估皮层-多裂肌配对关联刺激(PAS)对慢性下腰痛(CLBP)患者功能障碍、疼痛强度、生活质量及神经可塑性重塑的干预效应。具体目标包括:(1)比较主动PAS联合常规康复与伪刺激联合常规康复对Oswestry功能障碍指数(ODI)的改善效果;(2)分析PAS对疼痛(视觉模拟评分VAS、简化McGill疼痛问卷SFMPQ)、心理健康(疼痛灾难化量表PCS)、生活质量(健康调查简表SF-36)及脑功能成像的多维度影响;(3)阐明中枢-外周协同调控对CLBP慢性化病理机制的干预路径。  

Objectives of Study:

The aim of this study is to systematically assess the intervention effects of cortical-dolichoectasia paired-associated stimulation (PAS) on dysfunction, pain intensity, quality of life, and remodeling of neuroplasticity in patients with chronic lower back pain (CLBP) by means of a prospective randomized controlled trial. Specific objectives included (1) to compare the improvement effect of active PAS combined with conventional rehabilitation with that of pseudo-stimulation combined with conventional rehabilitation on the Oswestry Dysfunction Index (ODI); (2) to analyze the effect of PAS on pain (Visual Analog Scale VAS, Simplified McGill Pain Questionnaire SFMPQ), mental health (Pain Catastrophizing Scale PCS), quality of life (Short Form of Health Survey SF -36) and multidimensional effects of functional brain imaging; (3) to elucidate the intervention pathways of central-peripheral synergistic modulation on the pathomechanisms of CLBP chronicity.

干预措施:

将使用配备八字形线圈(翼直径 70 毫米)的 CCY-IA 磁刺激器(武汉伊瑞德医疗器械有限公司)进行多裂肌外周刺激,线圈定位于 L4-L5 棘突旁 2 厘米,参数设置为单脉冲模式,强度为运动阈值的 90%(定义为诱发多裂肌轻微收缩的最小强度),每 5 秒触发一次外周刺激。中枢刺激采用 CCY-II 磁刺激器(武汉伊瑞德),通过神经导航系统(LOCALITE)定位对侧 M1 区多裂肌代表区(通过TMS诱发多裂肌MEP≥50μV验证),参数为单脉冲模式,强度为静息运动阈值(RMT)的 110%,0.2Hz,在外周刺激后 25 毫秒精准触发。每次干预包含 180 对刺激(外周+中枢),总时长 15 分钟(5 秒/对 × 180 对),遵循 STDP 机制。神经导航整合个体高分辨率 T1 加权 MRI 数据,三维脑重建与实时红外追踪确保 M1 靶点定位,线圈切向放置并与中央前回轴线平行以优化电流流向。

干预措施代码:

Intervention:

Peripheral stimulation of the multifidus muscle will be performed using a CCY-IA magnetic stimulator (Wuhan Iridium Medical Devices Co., Ltd.) equipped with a figure-of-eight shaped coil (wing diameter 70 mm), which is positioned 2 cm adjacent to the L4-L5 spine, and parameterized in a single-pulse mode, with an intensity of 90% of the motor threshold (defined as the minimum intensity that evokes a slight contraction of the multifidus muscle), and triggered by peripheral stimulation every 5 seconds. Central stimulation was performed with a CCY-II magnetic stimulator (Wuhan Iridium), localized to the contralateral M1 zone of the multifidus representative area (verified by TMS-induced multifidus MEP ≥50 μV) by means of a neuronavigation system (LOCALITE), and parameterized in a single-pulse mode with an intensity of 110% of the resting motor threshold (RMT), 0.2 Hz, and triggered precisely 25 ms after the peripheral stimulation. Each intervention consisted of 180 stimulus pairs (peripheral + central) for a total duration of 15 minutes (5 s/pair × 180 pairs), following the STDP mechanism. Neuronavigation integrates individual high-resolution T1-weighted MRI data, 3D brain reconstruction with real-time infrared tracking to ensure M1 target localization, and coil placement tangential and parallel to the precentral gyrus axis to optimize current flow.

干预措施:

假干预的外周磁刺激采用CCY?IA磁刺激器配合垂直放置的非激活八字形线圈(翼直径70 mm),搭配隐藏式振动垫(强度 10%,低于感觉阈值)模拟肌肉触感,每 5 秒触发一次伪刺激,靶点同主动组(L4-L5 棘突旁 2 厘米)。中枢刺激通过 CCY-II 设备与 90°倾斜线圈(皮质电场衰减 >95%)模拟,靶点设为 M1 区手部“旋钮”区域(远离多裂肌代表区),强度为 RMT 的 10%,每 5 秒触发一次伪刺激并与外周伪刺激随机延迟(25ms±50ms),破坏 STDP 机制。神经导航坐标与主动组一致,但无真实神经调控效应,总时长、脉冲数与体感模拟均匹配主动方案。

干预措施代码:

Intervention:

Peripheral magnetic stimulation for the sham intervention was performed with a CCY-IA magnetic stimulator with vertically placed inactive figure-of-eight coils (wing diameter 70 mm) with hidden vibrating pads (intensity 10%, below sensory threshold) to simulate muscle touch, triggering pseudo-stimulation every 5 seconds, with the same target as in the active group (2 cm next to the L4-L5 spine). Central stimulation was simulated by a CCY-II device with a 90° tilting coil (cortical field attenuation >95%), targeting the "knob" area of the hand in the M1 region (away from the representative area of the multifidus muscle), with a strength of 10% of the RMT, and triggering pseudostimulation every 5 s with a randomized delay to peripheral pseudostimulation (25 ms ± 50 ms) to disrupt the STDP mechanism. that disrupted the STDP mechanism. The neuronavigation coordinates were consistent with those of the active group, but there was no real neuromodulation effect, and the total duration, number of pulses, and somatosensory simulation matched those of the active protocol.
