研究目的:

意识障碍患者多由于丘脑-皮层及皮层-皮层神经环路的连接减弱或停止所致。对环路关键节点的调控干预可能通过激活脑网络而恢复意识。现普遍认为意识恢复取决于多个皮层和皮层下网络间动态相互作用的重现,即丘脑-皮层及皮层-皮层环路都保持较高水平方可恢复,但目前干预仍以单一靶点试图激活完整意识网络,临床证明效果差。本研究在前期研究基础上提出以MCS患者为对象使用taVNS及SCS增强丘脑-皮层连接,分别联合tDCS提高皮层-皮层连接水平以实现意识的稳定提高与恢复。同时能直接激活全脑神经网络的SCS联合tDCS调控范式是否优于传统的taVNS联合tDCS也值得我们进一步探究。  

Objectives of Study:

Patients with impaired consciousness are mostly due to weakened or discontinued thalamo-cortical and cortico-cortical neural loops connections. Moderating interventions at key nodes of the loops may restore consciousness by activating brain networks. It is now generally accepted that recovery of consciousness depends on the reproduction of dynamic interactions between multiple cortical and subcortical networks, i.e., high levels of both thalamocortical and corticocortical loops, but current interventions still attempt to activate the complete consciousness network with a single target, which has proven to be clinically ineffective. In this study, we propose to use taVNS and SCS to enhance thalamocortical connections and tDCS to enhance cortical-cortical connections in MCS patients in order to achieve a stable increase in consciousness and recovery.Meanwile, whether the SCS combined with tDCS regulation paradigm that can directly activate the whole brain neural network is due to the traditional taVNS combined with tDCS is also worth further exploration.

盲法:

taVNS(SDZ-IIB,苏州医疗用品厂)刺激部位为耳部的耳甲区,主要是耳甲艇和耳甲腔部分。一对外观相同的夹子被放置在两只耳朵上。夹子设计有三个碳浸渍的硅胶尖端,其中一个作为公共端,用于支持耳廓的后表面,另外两个尖端被设计为刺激两个皮肤表面点,一个在外耳,另一个在舟骨,在外耳点的两个硅胶尖端分别放置于耳甲腔和耳甲艇。刺激器提供电流为1-1.5mA的电脉冲和4/20Hz的疏密波,电流强度设置以患者耐受而不出现明显不适。 HD-tDCS(VC-8000F,Nanjing Wogao)刺激部位为楔前叶。中心电极被放置于国际10-20系统的Pz位置,四个返回电极距离中心电极的距离约为3.5cm,分别置于Cz、P3、P4 和 POz。刺激电流为2mA的恒定电流,波升时间30s,波降时间30s,而假刺激刺激参数与真刺激一致,区别在于电压上升到2mA后立刻衰减到0mA并持续到结束以模拟开机刺激时电压的波升与波降。 SCS假刺激电压设计为0.1V,开启1s后自动关闭。SCS电极开启采用家属程控仪,而该程控仪只显示A、B两种数字。 真刺激与假刺激启动按钮将分别被两个标签A、B完全覆盖。治疗师并不知道按钮对应具体功能,每位患者治疗前由实验负责者告知治疗师刺激所使用的按钮编号。

Blinding:

The auricular region of the ear was targeted as the taVNS (SDZ-IIB, Suzhou Medical Supplies Factory, Suzhou, China) stimulation site, including mainly the cymba conchae and cavum conchae. A pair of clips were placed on both ears. The clips were designed with three carbon-impregnated silicone tips, one of which served as the common end for supporting the posterior surface of the auricle, and the other two tips were designed to stimulate two skin surface points, one at the outer ear and the other at the navicular bone, with the two silicone tips at the outer ear point placed on the auricular cavity and the auricular boat, respectively. The stimulator provided electrical pulses of 1–1.5 mA and sparse waves frequency of 4/20 Hz with the current intensity set so that the patient does not show a visible painful expression. Two identically looking instruments were used: one was capable of normal stimulation as positive stimulation, whereas the other had no current output and served as sham stimulation. The precuneus was selected as the HD-tDCS (4x1-C2, Soterix Medical Inc., New York, NY, USA) stimulation site. The central electrode was placed at position Pz of the international 10–20 system, and the four return electrodes were placed at a distance of approximately 3.5 cm from the central electrode at Cz, P3, P4, and POz positions. A constant current of 2 mA with a wave rise time of 30 s and a wave fall time of 30 s was employed for stimulation. The stimulation parameters of the sham stimulation group were the same as those in the positive stimulation with, except for the increase of the voltage to 2 mA, followed by its immediate decrease to 0 mA when the instrument was turned on. The positive and sham stimulation start buttons were completely covered by two labels, A and B, respectively. The therapist was not aware of the specific function of each button. The SCS sham stimulation voltage is designed to be 0.1V, and automatically closes after 1s of opening. The SCS electrode is opened with a family programmable controller, which only displays A and B numbers. Finally, the therapist was informed of the HD-tDCS button number and the taVNS machine number that should be used for the treatment of each patient by the study leader before the treatment
