重复经颅磁刺激
  • 文章类型: Journal Article
    背景:帕金森病(PD)常伴有睡眠障碍,影响患者的生活质量。虽然重复经颅磁刺激(rTMS)在改善自我报告的睡眠质量方面显示出希望,其对PD客观睡眠结构的影响仍未得到充分研究。睡眠障碍,包括快速眼动(REM)和慢波睡眠障碍,与认知功能下降和运动症状相关。这项研究调查了针对右背外侧前额叶皮质(DLPFC)的低频rTMS改善客观睡眠结构的效果,并探讨了PD患者的症状改善机制。
    方法:在本随机分组中,双盲,假对照试验,67名PD患者在右侧DLPFC上连续10天接受1-HzrTMS。多导睡眠图评估睡眠微观结构,而脑电图记录评估功率谱密度和睡眠纺锤活动。临床量表测量睡眠质量,运动症状,和基线时的认知,治疗后,rTMS后3个月。
    结果:rTMS组睡眠质量改善,运动症状,和认知后处理,坚持3个月的随访。rTMS后REM睡眠比例显着增加。在非REM睡眠期间,rTMS组表现出低频(0.5-2Hz)慢波脑电图频谱密度升高。认知增强与较低增量功率增加相关,而运动症状进展与纺锤频率和慢波睡眠百分比变化相关。
    结论:针对正确DLPFC的低频rTMS有望改善PD的临床症状和调节睡眠结构。这些发现表明症状改善与睡眠结构增强之间存在联系,强调需要进一步研究rTMS在PD管理中的治疗潜力。
    BACKGROUND: Parkinson\'s disease (PD) is often accompanied by sleep disturbances, impacting patients\' quality of life. While repetitive transcranial magnetic stimulation (rTMS) shows promise in improving self-reported sleep quality, its effects on objective sleep architecture in PD remain understudied. Sleep disturbances, including rapid eye movement (REM) and slow-wave sleep disturbances, correlate with cognitive decline and motor symptoms. This study investigated the effect of low-frequency rTMS targeting the right dorsolateral prefrontal cortex (DLPFC) modifying objective sleep architecture and explored symptom improvement mechanisms in PD patients.
    METHODS: In this randomized, double-blind, sham-controlled trial, 67 PD patients received 10 consecutive days of 1-Hz rTMS over the right DLPFC. Polysomnography assessed sleep microstructure, while electroencephalogram recordings evaluated power spectral density and sleep spindle activity. Clinical scales measured sleep quality, motor symptoms, and cognition at baseline, post-treatment, and 3 months post-rTMS.
    RESULTS: The rTMS group exhibited improvements in sleep quality, motor symptoms, and cognition post-treatment, persisting at the 3-month follow-up. There was a notable increase in the REM sleep proportion post-rTMS. The rTMS group exhibited elevated low-frequency (0.5-2 Hz) slow-wave electroencephalogram spectral density during non-REM sleep. Cognitive enhancement correlated with increased lower delta power, while motor symptom progression correlated with spindle frequency and slow-wave sleep percentage changes.
    CONCLUSIONS: Low-frequency rTMS targeting the right DLPFC holds promise for improving clinical symptoms and modulating sleep architecture in PD. These findings suggest a link between symptom improvement and sleep structure enhancement, highlighting the need for further investigation into the therapeutic potential of rTMS in PD management.

    各种非侵入性脑刺激(NIBS)干预对自闭症谱系障碍的疗效和可接受性尚不清楚。我们对NIBS减轻自闭症症状的随机对照试验(RCT)进行了系统评价(INPLASY202370003)。16篇文章(N=709)符合网络荟萃分析的纳入标准。效果大小报告为标准化平均差异(SMD)或比值比,具有95%置信区间(CI)。14项积极的NIBS干预措施,包括经颅直流电刺激(tDCS),重复经颅磁刺激,并对经颅脉冲刺激进行分析。与假对照(SMD=-1.40,95CIs=-2.67至-0.14)相比,只有左背外侧前额叶皮层的阳极tDCS与脑外位置的阴极tDCS(atDCS_F3ctDCS_E)显着改善了自闭症症状。NIBS干预措施均未显着改善自闭症参与者的社交症状或受限/重复行为。此外,与假对照相比,没有积极的NIBS干预表现出显著的脱落率差异,所有干预均未报告严重不良事件.
    The efficacy and acceptability of various non-invasive brain stimulation (NIBS) interventions for autism spectrum disorder remain unclear. We carried out a systematic review for randomized controlled trials (RCTs) regarding NIBS for reducing autistic symptoms (INPLASY202370003). Sixteen articles (N = 709) met the inclusion criteria for network meta-analysis. Effect sizes were reported as standardized mean differences (SMDs) or odds ratios with 95% confidence intervals (CIs). Fourteen active NIBS interventions, including transcranial direct current stimulation (tDCS), repetitive transcranial magnetic stimulation, and transcranial pulse stimulation were analyzed. Only anodal tDCS over the left dorsolateral prefrontal cortex paired with cathodal tDCS over an extracephalic location (atDCS_F3+ctDCS_E) significantly improved autistic symptoms compared to sham controls (SMD = -1.40, 95%CIs = -2.67 to -0.14). None of the NIBS interventions markedly improved social-communication symptoms or restricted/repetitive behaviors in autistic participants. Moreover, no active NIBS interventions exhibited significant dropout rate differences compared to sham controls, and no serious adverse events were reported for any intervention.

    重复经颅磁刺激(rTMS)是帕金森病(PD)的一种有效的非侵入性神经调节技术。然而,rTMS的疗效在个体之间差异很大。本研究旨在探讨PD患者对rTMS反应的相关因素。
    我们回顾性分析了70例特发性PD患者的反应,这些患者连续14天接受rTMS,以开放标记(n=31)或随机,双盲,安慰剂对照试验(RCT)(n=39)。采用帕金森病联合评定量表第三部分(UPDRSIII)对PD患者的运动症状进行评估。根据以前的研究,UPDRSIII分为六个症状群:轴向功能障碍,静止性震颤,刚性,影响左右四肢的运动迟缓,和姿势震颤。随后,分析了rTMS对不同运动症状群和临床预测因子的疗效。
    治疗14天后,在开放标签试验和RCT中,只有UPDRSIII总评分和刚性评分得到改善.多元线性回归分析结果表明,基线刚性评分(β=0.37,p=0.047)和RMT(β=0.30,P=0.02)正预测UPDRSIII的改善。基线刚度评分(β=0.55,P<0.0001)被确定为预测刚度改善的独立因素。
    这项研究表明,经过14天的治疗,UPDRSIII总评分和僵硬度得到了显着改善,基线刚性评分和RMT被确定为治疗反应的预测因子,强调个性化治疗的必要性。
    UNASSIGNED: Repetitive transcranial magnetic stimulation (rTMS) is an effective noninvasive neuromodulation technique for Parkinson\'s disease (PD). However, the efficacy of rTMS varies widely between individuals. This study aimed to investigate the factors related to the response to rTMS in PD patients.
    UNASSIGNED: We retrospectively analyzed the response of 70 idiopathic PD patients who underwent rTMS for 14 consecutive days targeting the supplementary motor area (SMA) in either an open-label trail (n = 31) or a randomized, double-blind, placebo-controlled trial (RCT) (n = 39). The motor symptoms of PD patients were assessed by the United Parkinson\'s Disease Rating Scale Part III (UPDRSIII). Based on previous studies, the UPDRSIII were divided into six symptom clusters: axial dysfunction, resting tremor, rigidity, bradykinesia affecting right and left extremities, and postural tremor. Subsequently, the efficacy of rTMS to different motor symptom clusters and clinical predictors were analyzed in these two trails.
    UNASSIGNED: After 14 days of treatment, only the total UPDRSIII scores and rigidity scores improved in both the open-label trial and the RCT. The results of multiple linear regression analysis indicated that baseline rigidity scores (β = 0.37, p = 0.047) and RMT (β = 0.30, P = 0.02) positively predicted the improvement of UPDRSIII. The baseline rigidity score (β = 0.55, P < 0.0001) was identified as an independent factor to predict the improvement of rigidity.
    UNASSIGNED: This study demonstrated significant improvements in total UPDRSIII scores and rigidity after 14-day treatment, with baseline rigidity scores and RMT identified as predictors of treatment response, underscoring the need for individualized therapy.

    UNASSIGNED: Executive dysfunction is a core symptom of vascular cognitive impairment (VCI), which seriously affects patients\' prognosis. This paper aims to investigate the effectiveness of rTMS on executive function in VCI.
    UNASSIGNED: The databases selected for this study included Pubmed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, China Science and Technology Journal Database (VIP), and China Biology Medicine Disc (CBM). The screening times were conducted from the time of library construction until August 23, 2023. The inclusion criteria for this meta-analysis were randomized controlled trials (RCTs) on rTMS for VCI, which include executive function scores. The primary metrics were executive subscale scores of the Cognitive Comprehensive Scale and total scores of the Executive Specificity Scale. The secondary metrics were subscale scores of the Executive Specificity Scale. The quality of each eligible study was assessed using the Cochrane Risk of Bias tool. Meta-analysis and bias analysis were performed using Stata (version 16.0) and RevMan (version 5.3).
    UNASSIGNED: A total of 20 high-quality clinical RCTs with 1,049 samples were included in this paper. The findings from the primary outcomes revealed that within the rTMS group, there were significantly higher scores observed for the executive sub-item on the cognitive composite scale (SMD = 0.93, 95% CI = 0.77-1.08, p < 0.00001, I 2 = 14%) and the total score on the executive specific scale (SMD = 0.69, 95% CI = 0.44-0.94, p < 0.00001, I 2 = 0%) compared to the control group. As for the secondary outcome measures, as shown by the Trail Making Test-A (time) (MD = -35.75, 95% CI = -68.37 to -3.12, p = 0.03, I 2 = 55%), the Stroop-C card (time) (SMD = -0.46, 95% CI = -0.86 to -0.06, p = 0.02, I 2 = 0%) and the Stroop-C card (correct number) (SMD = 0.49, 95% CI = 0.04-0.94, p = 0.03, I 2 = 0%), the experimental group shorts time and enhances accuracy of executive task in comparison to the control group. Subgroup analysis of the main outcome demonstrated that intermittent theta burst stimulation (iTBS), higher frequency, lower intensity, longer duration, and combined comprehensive therapy exhibited superior efficacy.
    UNASSIGNED: rTMS is effective in the treatment of the executive function of VCI. The present study has some limitations, so multi-center, large-sample, objective indicators and parameters are needed to further explore in the future.Systematic review registration:https://www.crd.york.ac.uk/prospero/, CRD42023459669.

  • 文章类型: Systematic Review
    背景:非侵入性脑刺激(NIBS)联合认知训练(CT)可能在改善阿尔茨海默病(AD)和轻度认知障碍(MCI)患者的认知功能方面显示出一定的前景。然而,涉及NIBS联合CT的临床试验或荟萃分析数据显示有争议的结果.本系统评价和荟萃分析的目的是评估NIBS联合CT对改善AD和MCI患者整体认知和其他特定认知领域的短期和长期影响。
    方法:本系统评价和荟萃分析按照系统评价和荟萃分析(PRISMA)指南的首选报告项目进行。五个电子数据库,包括PubMed,WebofScience,EBSCO,从成立到2023年11月20日,搜索了Cochrane图书馆和Embase。采用PEDro量表和Cochrane的偏倚风险评估对纳入研究的偏倚风险和方法学质量进行评价。所有统计分析均使用ReviewManager5.3进行。
    结果:我们纳入了15项研究,共685名患者。PEDro量表用于评估方法学质量,平均得分为7.9分。荟萃分析结果显示NIBS联合CT对改善AD和MCI患者的整体认知功能有明显的疗效(SMD=0.52,95%CI(0.18,0.87),p=0.003),尤其是重复经颅磁刺激(rTMS)联合CT(SMD=0.46,95%CI(0.14,0.78),p=0.005)。与NIBS联合CT组相比,AD可实现整体认知改善(SMD=0.77,95%CI(0.19,1.35),p=0.01)。经颅直流电刺激(tDCS)联合CT可以改善AD和MCI的语言功能(SMD=0.29,95%CI(0.03,0.55),p=0.03)。在评估后续行动中,rTMS联合CT在整体认知中对AD和MCI表现出更大的治疗反应(SMD=0.55,95%CI(0.09,1.02),p=0.02)。AD可以实现整体认知(SMD=0.40,95%CI(0.03,0.77),p=0.03)和注意力/工作记忆(SMD=0.72,95%CI(0.23,1.20),p=0.004)NIBS联合CT组评估随访后的改善。
    结论:总体而言,NIBS联合CT,特别是rTMS结合CT,对改善全球认知有短期和后续效应,主要在AD患者中。tDCS联合CT在改善AD和MCI语言功能方面具有优势。未来更多的研究需要评估NIBS联合CT对认知恶化患者其他特定认知领域的认知效果。
    Non-invasive brain stimulation (NIBS) combined with cognitive training (CT) may have shown some prospects on improving cognitive function in patients with Alzheimer\'s disease (AD) and mild cognitive impairment (MCI). However, data from clinical trials or meta-analysis involving NIBS combined with CT have shown controversial results. The aim of this systematic review and meta-analysis was to evaluate short-term and long-term effects of NIBS combined with CT on improving global cognition and other specific cognitive domains in patients with AD and MCI.
    This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five electronic databases including PubMed, Web of Science, EBSCO, Cochrane Library and Embase were searched up from inception to 20 November 2023. The PEDro scale and the Cochrane\'s risk of bias assessment were used to evaluate risk of bias and methodological quality of included studies. All statistical analyses were conducted with Review Manager 5.3.
    We included 15 studies with 685 patients. The PEDro scale was used to assess methodological quality with a mean score of 7.9. The results of meta-analysis showed that NIBS combined with CT was effective on improving global cognition in AD and MCI (SMD = 0.52, 95% CI (0.18, 0.87), p = 0.003), especially for patients accepting repetitive transcranial magnetic stimulation (rTMS) combined with CT (SMD = 0.46, 95% CI (0.14, 0.78), p = 0.005). AD could achieve global cognition improvement from NIBS combined with CT group (SMD = 0.77, 95% CI (0.19, 1.35), p = 0.01). Transcranial direct current stimulation (tDCS) combined with CT could improve language function in AD and MCI (SMD = 0.29, 95% CI (0.03, 0.55), p = 0.03). At evaluation follow-up, rTMS combined with CT exhibited larger therapeutic responses to AD and MCI in global cognition (SMD = 0.55, 95% CI (0.09, 1.02), p = 0.02). AD could achieve global cognition (SMD = 0.40, 95% CI (0.03, 0.77), p = 0.03) and attention/working memory (SMD = 0.72, 95% CI (0.23, 1.20), p = 0.004) improvement after evaluation follow-up from NIBS combined with CT group.
    Overall, NIBS combined with CT, particularly rTMS combined with CT, has both short-term and follow-up effects on improving global cognition, mainly in patients with AD. tDCS combined with CT has advantages on improving language function in AD and MCI. Future more studies need evaluate cognitive effects of NIBS combined with CT on other specific cognitive domain in patients with cognitive deterioration.

    UNASSIGNED: The rehabilitation of central post-stroke pain (CPSP) is a complex clinical challenge, and repetitive transcranial magnetic stimulation (rTMS) has been widely applied in the research of neurofunctional recovery following stroke. However, there is currently no reliable evidence-based medicine supporting the efficacy of rTMS in central post-stroke pain. This review aims to evaluate the effects of rTMS on central post-stroke pain.
    UNASSIGNED: Following the PRISMA guidelines, we conducted searches on PubMed, Cochrane Library, Embase, Web of Science, CNKI, and Wan Fang Data Knowledge Service Platform. We searched for randomized controlled trials (RCTs) investigating the use of rTMS in treating central post-stroke pain, and conducted screening based on inclusion and exclusion criteria. Characteristics of the included RCTs were extracted. The heterogeneity of the trials was assessed using the I2 statistic. Meta-analysis was performed using Stata 17 software. Bias risk and methodological quality were evaluated using the Cochrane RoB 2 tool and the Pedro scale.
    UNASSIGNED: A total of six randomized controlled trials involving 288 patients met our inclusion criteria. In our analysis, rTMS was more effective in treating patients with CPSP compared to the placebo group (SMD=-1.15, 95% CI: -1.69, -0.61, P < 0.001). Furthermore, results from subgroup analysis indicated no statistically significant difference in the improvement of pain for durations exceeding 6 months when comparing rTMS to conventional treatment (SMD=-0.80, 95% CI: -1.63, 0.03, P = 0.059).
    UNASSIGNED: TMS can alleviate pain in CPSP patients and improve their motor function, but its effects on depression, anxiety, and MEP-latency are not significant.

    本系统综述和荟萃分析旨在评估重复经颅磁刺激(rTMS)在带状疱疹后遗神经痛(PHN)中的疗效。
    通过在四个数据库中进行广泛搜索,直到2023年10月,我们选择了符合我们特定标准的五项随机对照试验,共涉及257名患者。对于连续的结果,计算标准化平均差(SMD).使用Cochran的I2和Q统计来评估研究之间的异质性,采用I2值超过50%的随机效应模型。为了评估潜在的出版偏见,我们利用了漏斗图和艾格测试。
    我们的分析发现,rTMS降低了总体视觉模拟量表(VAS)(SMD:-1.52,95%CI:-2.81至-0.23,p=0.02),治疗后1个月的VAS(SMD:-2.21,95%CI:-4.31至-0.10,p=0.04),治疗后3个月的VAS(SMD:-1.51,95%CI:-2.81至-0.22,p=0.02),以及与假rTMS组相比,患者的整体变化印象量表(PGIC)(SMD:-1.48,95%CI:-2.87至-0.09,p=0.04)和简短的McGill疼痛问卷(SF-MPQ)(SMD:-1.25,95%CI:-2.41至-0.09,p=0.03)。
    我们的研究表明,rTMS可能对PHN症状有潜在的缓解作用。然而,由于研究数量有限和RTMS参数的变化,涉及更多不同人群的更大样本研究,以及进一步澄清最合适的刺激方案,仍然需要。

    UNASSIGNED: This systematic review and meta-analysis aimed to evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in postherpetic neuralgia (PHN).
    UNASSIGNED: Through an extensive search in four databases until October 2023, we selected five randomized controlled trials adhering to our specific criteria, involving 257 patients in total. For continuous outcomes, the standardized mean difference (SMD) was calculated. Heterogeneity among the studies was assessed using Cochran\'s I 2 and Q statistics, adopting a random-effects model for I 2 values over 50%. For assessing potential publication bias, we utilized both funnel plot and Egger\'s test.
    UNASSIGNED: Our analysis found that rTMS reduced the overall visual analogue scale (VAS) (SMD: -1.52, 95% CI: -2.81 to -0.23, p = 0.02), VAS at 1 month post-treatment (SMD: -2.21, 95% CI: -4.31 to -0.10, p = 0.04), VAS at 3 months post-treatment (SMD: -1.51, 95% CI: -2.81 to -0.22, p = 0.02), as well as patients\' global impression of change scale (PGIC) (SMD: -1.48, 95% CI: -2.87 to -0.09, p = 0.04) and short-form McGill pain questionnaire (SF-MPQ) (SMD: -1.25, 95% CI: -2.41 to -0.09, p = 0.03) compared to the sham-rTMS group.
    UNASSIGNED: Our study suggests that rTMS might have a potential alleviating effect on PHN symptoms. However, due to the limited number of studies and variations in rTMS parameters, larger sample studies involving more diverse populations, as well as further clarification of the most appropriate stimulation protocol, are still needed.

    重复经颅磁刺激(rTMS)是一种治疗策略,有望改善创伤性脑损伤(TBI)后的临床后遗症。这些改善与神经元及其突触连接的神经可塑性变化有关。然而,据推测,rTMS也可能调节小胶质细胞和星形胶质细胞,可能增强他们的神经保护能力。这项研究旨在研究高频rTMS对小胶质细胞和星形胶质细胞的影响,这可能有助于其神经保护作用。采用Feeney减重法建立中度TBI大鼠模型。通过观察大鼠突触超微结构和神经元凋亡水平,评价高频rTMS对大鼠的神经保护作用。通过免疫荧光染色和蛋白质印迹评估小胶质细胞和星形胶质细胞中几种重要的炎症相关蛋白的水平。我们的发现表明,可以通过rTMS调节小胶质细胞和星形胶质细胞来挽救受损的神经元。这种调节在保持突触超微结构和抑制神经元凋亡中起关键作用。在小胶质细胞中,我们观察到rTMS抑制了促炎因子(CD16,IL-6和TNF-α)的水平,并促进了抗炎因子(CD206,IL-10和TNF-β)的水平。rTMS还降低了小胶质细胞内的焦亡水平和焦亡相关蛋白(NLRP3,Caspase-1,GSDMD,IL-1β和IL-18)。此外,rTMS下调星形胶质细胞中P75NTR的表达和上调IL33的表达。这些发现表明,小胶质细胞和星形胶质细胞的调节是rTMS减轻中度TBI后神经元炎症损伤的机制。
    Repetitive transcranial magnetic stimulation (rTMS) is a therapeutic strategy that shows promise in ameliorating the clinical sequelae following traumatic brain injury (TBI). These improvements are associated with neuroplastic changes in neurons and their synaptic connections. However, it has been hypothesized that rTMS may also modulate microglia and astrocytes, potentially potentiating their neuroprotective capabilities. This study aims to investigate the effects of high-frequency rTMS on microglia and astrocytes that may contribute to its neuroprotective effects. Feeney\'s weight-dropping method was used to establish rat models of moderate TBI. To evaluate the neuroprotective effect of high frequency rTMS on rats by observing the synaptic ultrastructure and the level of neuron apoptosis. The levels of several important inflammation-related proteins within microglia and astrocytes were assessed through immunofluorescence staining and western blot. Our findings demonstrate that injured neurons can be rescued through the modulation of microglia and astrocytes by rTMS. This modulation plays a key role in preserving the synaptic ultrastructure and inhibiting neuronal apoptosis. Among microglia, we observed that rTMS inhibited the levels of proinflammatory factors (CD16, IL-6 and TNF-α) and promoted the levels of anti-inflammatory factors (CD206, IL-10 and TNF-β). rTMS also reduced the levels of pyroptosis within microglia and pyroptosis-related proteins (NLRP3, Caspase-1, GSDMD, IL-1β and IL-18). Moreover, rTMS downregulated P75NTR expression and up-regulated IL33 expression in astrocytes. These findings suggest that regulation of microglia and astrocytes is the mechanism through which rTMS attenuates neuronal inflammatory damage after moderate TBI.

    背景:左角回的神经导航重复经颅磁刺激(rTMS)已被广泛研究用于治疗遗忘型轻度认知障碍(aMCI)。虽然在两个海马网络异常,前颞(AT)和后内侧(PM)网络,与aMCI一致,是rTMS的潜在治疗靶点,rTMS对海马网络连接的治疗作用的潜在机制仍然未知.这里,我们评估了左角回rTMS对这些网络活动的影响,并探讨了治疗反应是否归因于aMCI患者临床应用目标(组平均最佳部位)与个性化目标之间的距离.
    方法:在20次针对左角回的假对照rTMS治疗后,60名临床诊断为aMCI的受试者参与了这项研究。在rTMS前后进行静息状态功能磁共振成像和神经心理学评估。使用基于种子的功能连通性分析和双因素重复测量方差分析(ANOVA)评估PM和AT网络中的功能连通性改变。然后,我们计算了功能连通性变化与临床评定量表之间的相关性。最后,我们检查了临床应用目标和个性化目标之间的欧氏距离是否可以预测后续治疗反应.
    结果:与假手术组相比,活跃的rTMS组显示rTMS诱导的内侧颞叶-AT网络内的功能连接失活,与情景记忆得分变化呈负相关。此外,活动rTMS降低了PM和AT网络中变化的相互依赖性。最后,临床应用目标距离和个性化目标距离之间的欧氏距离可以预测活动rTMS组随后的网络杠杆反应.
    结论:神经导航rTMS选择性调节aMCI患者PM和AT海马网络中广泛的功能连接异常,调节海马-AT网络连接可以有效逆转记忆障碍。结果还强调了功能磁共振成像个性化目标的必要性。
    BACKGROUND: Neuro-navigated repetitive transcranial magnetic stimulation (rTMS) of the left angular gyrus has been broadly investigated for the treatment of amnestic mild cognitive impairment (aMCI). Although abnormalities in two hippocampal networks, the anterior-temporal (AT) and posterior-medial (PM) networks, are consistent with aMCI and are potential therapeutic targets for rTMS, the underlying mechanisms of the therapeutic effects of rTMS on hippocampal network connections remain unknown. Here, we assessed the impact of left angular gyrus rTMS on activity in these networks and explored whether the treatment response was due to the distance between the clinically applied target (the group average optimal site) and the personalized target in patients with aMCI.
    METHODS: Sixty subjects clinically diagnosed with aMCI participated in this study after 20 sessions of sham-controlled rTMS targeting the left angular gyrus. Resting-state functional magnetic resonance imaging and neuropsychological assessments were performed before and after rTMS. Functional connectivity alterations in the PM and AT networks were assessed using seed-based functional connectivity analysis and two-factor repeated measures analysis of variance (ANOVA). We then computed the correlations between the functional connectivity changes and clinical rating scales. Finally, we examined whether the Euclidean distance between the clinically applied and personalized targets predicted the subsequent treatment response.
    RESULTS: Compared with the sham group, the active rTMS group showed rTMS-induced deactivation of functional connectivity within the medial temporal lobe-AT network, with a negative correlation with episodic memory score changes. Moreover, the active rTMS lowers the interdependency of changes in the PM and AT networks. Finally, the Euclidean distance between the clinically applied and personalized target distances could predict subsequent network lever responses in the active rTMS group.
    CONCLUSIONS: Neuro-navigated rTMS selectively modulates widespread functional connectivity abnormalities in the PM and AT hippocampal networks in aMCI patients, and the modulation of hippocampal-AT network connectivity can efficiently reverse memory deficits. The results also highlight the necessity of personalized targets for fMRI.

    神经性吞咽困难是由中枢神经系统和周围神经系统的问题引起的吞咽困难。在帕金森病和中风等疾病中尤为普遍。它严重影响受影响个人的生活质量,并造成额外负担,比如营养不良,吸入性肺炎,窒息,甚至因饮食不当而窒息而死亡。物理疗法提供高疗效和低成本的非侵入性治疗。支持在吞咽困难治疗中使用物理疗法的证据正在增加,包括神经肌肉电刺激等技术,感官刺激,经颅直流电刺激,重复经颅磁刺激.虽然初步研究显示出了有希望的结果,具体治疗方案的有效性仍需进一步验证.目前,缺乏科学证据来指导患者选择,制定适当的治疗方案,并准确评估治疗结果。因此,这篇综述的主要目的是回顾现有研究的结果,总结物理治疗在吞咽困难管理中的应用,我们还讨论了物理治疗神经性吞咽困难的机制和治疗方法。
    A neurogenic dysphagia is dysphagia caused by problems with the central and peripheral nervous systems, is particularly prevalent in conditions such as Parkinson\'s disease and stroke. It significantly impacts the quality of life for affected individuals and causes additional burdens, such as malnutrition, aspiration pneumonia, asphyxia, or even death from choking due to improper eating. Physical therapy offers a non-invasive treatment with high efficacy and low cost. Evidence supporting the use of physical therapy in dysphagia treatment is increasing, including techniques such as neuromuscular electrical stimulation, sensory stimulation, transcranial direct current stimulation, and repetitive transcranial magnetic stimulation. While initial studies have shown promising results, the effectiveness of specific treatment regimens still requires further validation. At present, there is a lack of scientific evidence to guide patient selection, develop appropriate treatment regimens, and accurately evaluate treatment outcomes. Therefore, the primary objectives of this review are to review the results of existing research, summarize the application of physical therapy in dysphagia management, we also discussed the mechanisms and treatments of physical therapy for neurogenic dysphagia.
