研究目的:

(1)比较不同靶点rTMS(SMA、DLPFC)与安慰剂刺激对CNLBP患者姿势控制能力(以Biodex平衡系统OSI、APSI、MLSI为核心指标)及临床结局(疼痛强度NPRS、运动恐惧TSK)的改善效果。 (2)利用fNIRS技术,探究rTMS干预前后CNLBP患者在执行静态(睁眼稳定)与动态(睁眼不稳定)姿势控制任务时,运动相关皮层激活模式的变化,阐明不同靶点rTMS对中枢运动控制功能的特异性调控作用。 (3)分析CNLBP患者姿势控制能力的改善(Biodex指标变化)与运动相关皮层激活变化(fNIRS的HbO2浓度变化)之间的关系,验证“中枢神经功能重塑是姿势控制改善的基础”这一核心假设。  

Objectives of Study:

To compare the improvement effects of rTMS targeting different cortical regions (SMA, DLPFC) versus sham stimulation on postural control ability (with Biodex Balance System-derived OSI, APSI, and MLSI as core metrics) and clinical outcomes (pain intensity assessed by NPRS; kinesiophobia assessed by TSK) in patients with CNLBP. (2)? To employ fNIRS to investigate changes in the activation patterns of motor-related cortical regions in patients with CNLBP during the execution of static (eyes-open stable platform) and dynamic (eyes-open unstable platform) postural control tasks, before and after rTMS intervention. This aims to elucidate the target-specific regulatory effects of different rTMS protocols on central motor control function. (3)? To analyze the relationship between the improvement in postural control ability (changes in Biodex metrics) and alterations in motor-related cortical activation (changes in HbO? concentration measured by fNIRS) in patients with CNLBP. This analysis will test the core hypothesis that "central nervous system functional remodeling underlies improvements in postural control."

干预措施:

Interventions:

组别:

rTMS靶向于SMA组

样本量:

14

Group:

rTMS targeting the SMA Group

Sample size:

干预措施:

刺激强度设定为RMT的95%,即95%RMT,以10 Hz频率施加40列脉冲,每列50次,持续5秒,组间间隔为25秒,在20分钟内总共进行2000次刺激,每周5次,持续2周。在10 - 20系统中先定位Cz(正中线顶点),然后沿正中线向前移动约1.8?cm(约2?cm),即得到SMA的皮层投影位置。该定位已被用于tDCS/TMS研究中对SMA的刺激。操作过程中线圈平面与头部相切,线圈手柄指向后方,并与中矢线呈45°。

干预措施代码:

Intervention:

The stimulation protocol involved high-frequency 10?Hz repetitive transcranial magnetic stimulation, with 50 pulses per train, each train lasting 5?seconds, for a total of 40 trains (yielding 2000 total pulses), at an intensity set to 90% of the resting motor threshold (RMT), administered once daily for 10 consecutive days. The stimulation target was initially localized to the F3 electrode position according to the International 10–20 system, corresponding to approximately 10–20% of the scalp distance from the anterior-lateral aspect of the left frontal lobe; the Beam-F3 method was then applied to shift approximately 1?cm anterolaterally from the standard F3 point to better approximate Brodmann areas 9/46. During the procedure, the coil plane was maintained tangentially to the scalp, with the coil handle oriented posteriorly and forming a 45° angle with the midsagittal line.

Group:

rTMS targeting the DLPFC Group

Sample size:

干预措施:

高频10 Hz,脉冲序列50个,持续5秒,总序列数40组,总脉冲数2000个,刺激强度设定为静息运动阈值(RMT)的90%,每日1次,连续干预10天。采用国际10 - 20系统测量后得到的F3电极位置,即左额叶前外侧约10% - 20%的头皮距离。Beam - F3方法进一步在F3基础上向前外侧偏移约1?cm,以更贴近Brodmann 9/46区。操作过程中线圈平面与头部相切,线圈手柄指向后方,并与中矢线呈45°。

干预措施代码:

Intervention:

The stimulation protocol consisted of high-frequency 10?Hz repetitive transcranial magnetic stimulation, with 50 pulses per train, each train lasting 5?seconds, for a total of 40 trains (equivalent to 2000 total pulses), delivered at an intensity of 90% of the resting motor threshold (RMT), administered once daily for 10 consecutive days. The stimulation target was initially localized to the F3 electrode position as defined by the International 10–20 system, which corresponds approximately to 10–20% of the scalp distance from the anterior-lateral region of the left frontal lobe. The Beam-F3 method was then applied to shift the target approximately 1?cm anterolaterally from the standard F3 point to better approximate Brodmann areas 9/46. During the procedure, the coil plane was maintained tangentially to the scalp, with the coil handle oriented posteriorly and forming a 45° angle relative to the midsagittal line.

Intervention code:

组别:

假刺激组

样本量:

14

Group:

Sham Stimulation Group

Sample size:

干预措施:

对左侧SMA进行rTMS,使用与SMA组相同刺激,即95%RMT,以10 Hz频率施加40列脉冲,每列50次,持续5秒,组间间隔为25秒,在20分钟内总共进行2000次刺激,每周5次,持续2周。为实现盲法,安慰剂组将线圈倾斜约45°放置于头皮上,使磁场几乎不进入大脑,但仍保持线圈与头皮接触,从而产生与真实刺激相同的点击声和轻微振动,使受试者难以辨别真实与安慰剂刺激。

干预措施代码:

Intervention:

Repetitive transcranial magnetic stimulation (rTMS) was delivered to the left supplementary motor area (SMA) using identical stimulation parameters as the SMA group: intensity at 95% of the resting motor threshold (RMT), frequency of 10?Hz, 40 trains of pulses with 50 pulses per train, each train lasting 5 seconds, and an inter-train interval of 25 seconds, resulting in a total of 2000 pulses administered over 20 minutes. The intervention was applied 5 times per week for 2 consecutive weeks. For the sham (placebo) condition, blinding was achieved by tilting the coil approximately 45° relative to the scalp, which minimized magnetic field penetration into the brain while maintaining physical contact with the scalp. This configuration produced auditory clicks and mild tactile vibrations perceptually indistinguishable from active stimulation, thereby preventing participants from reliably distinguishing between real and sham stimulation.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列的产生:本研究采用区组随机化方法。由不参与本试验受试者招募、干预实施及结果评估的独立统计人员,使用统计软件(如:SPSS 26.0 或 R 语言)生成随机数字序列。区组长度设定为 6(即每6名受试者为一个区组,确保SMA组、DLPFC组与假刺激组在每个区组内人数均衡)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Random Sequence Generation? A block randomization method was employed in this study. An independent statistician, who was not involved in participant recruitment, intervention delivery, or outcome assessment, generated the random number sequence using statistical software (e.g., SPSS 26.0 or R). The block size was set to 6 (i.e., every six consecutive participants formed one block, ensuring balanced allocation of the SMA-targeted rTMS group, DLPFC-targeted rTMS group, and sham stimulation group within each block).
