研究目的:
|
脑梗死后机体会自发启动内源性脑可塑性改变,其中,大脑结构保留度相对较高的患者,其患侧皮层临近区域间以及双侧半球间的竞争性抑制失衡,是导致肢体痉挛难以恢复的主要机制之一。以此为出发点,我们提出“提高脑梗死患者患侧病损区域皮层兴奋性,抑制健侧半球兴奋性”的治疗策略,使用电针联合低频rTMS治疗手段,观察其改善脑梗死后上肢痉挛的临床疗效,并基于脑可塑性理论明确其作用机制。

Objectives of Study:
|
After cerebral infarction, the body will spontaneously initiate endogenous brain plasticity changes. Among them, in patients with relatively high brain structure retention, the competitive inhibition imbalance between adjacent regions of the affected side cortex and bilateral hemispheres is one of the main mechanisms leading to the difficult recovery of limb spasm.Taking this as a starting point, we proposed a treatment strategy of "improving cortical excitability of the lesion area on the affected side of cerebral infarction and inhibiting the excitability of the healthy side hemisphere", using electroacupuncture combined with low-frequency rTMS to observe the clinical efficacy of improving upper limb spasm after cerebral infarction, and clarifying the mechanism of action based on the theory of brain plasticity.

药物成份或治疗方案详述:
|
A组:电针治疗:选穴:主穴参照《针灸治疗学》中风病篇选取阳经穴位肩峰、肩贞、肩髎、臂臑、手三里、曲池、外关、合谷,配穴依据辨证及其它伴发症状适当选取;针具:采用一次性针灸针(0.30mm×40mm毫针);针刺方法:直刺进针后调整针刺深度及角度待患者有酸、麻、胀、痛等得气感,主穴连接韩氏电针仪,采用连续波,频率50Hz(诸多研究表明,高频电针对改善上运动神经元引起的肢体痉挛临床疗效更佳),强度以患者能够耐受为度,留针30min;疗程:每周治疗5次,连续治疗4周。低频rTMS治疗:刺激部位:健侧运动皮层M1区;刺激频率:1Hz;刺激强度:80%MT值,每序列15个脉冲,共80个序列,每序列间隔5s;疗程:每周治疗5次,连续治疗4周。
B组:假电针治疗:穴位处方同电针组方案,安慰针具通过胶垫直刺向穴位刺入,刚一破皮后针尖迅速退回至软垫中,不直接接触患者皮肤,其余方案同电针组。低频rTMS治疗:治疗方案同组(1)rTMS治疗。
C组:电针治疗:同组(1)电针治疗。假低频rTMS治疗:将rTMS治疗线圈离开患者头部健侧运动皮层M1区10cm,即治疗效应区以外的位置,余方案同组(1)rTMS治疗。
试验期间,两组受试者除接受方案规定的治疗外,应同时进行必要的脑血管疾病二级预防和现代康复治疗。

Description for medicine or protocol of treatment in detail:
|
Group A: cupping treatment: choose acupuncture point: main point with reference to the acupuncture therapy in stroke article Yang meridians shoulder peak, chien cheng Er, shoulder liao, arm, hand three mile, li 11, outside, or valley, with acupuncture point according to syndrome differentiation and other symptoms with appropriate selection.Needle: disposable acupuncture needle (0.30mm x 40mm filiform needle);Acupuncture methods: adjust the Angle of acupuncture depth and straight into the needle after treat patients such as acid, hemp, bilge, pain QiGan, main point connection asaps cupping apparatus, adopt continuous wave, frequency 50 hz (many studies have shown that the high frequency electricity to improve on motor neuron caused by limb spasm clinical curative effect is better), strength for patients able to tolerate, retaining needle 30 min;Treatment course: 5 times a week for 4 weeks.Low frequency rTMS treatment: stimulation site: m1-area of lateral motor cortex;Stimulus frequency: 1Hz;Stimulus intensity: 80%MT value, 15 pulses per sequence, a total of 80 sequences, each sequence interval 5s;Treatment course: 5 times a week for 4 weeks.
Group B: sham electroacupuncture treatment: acupoint prescription was the same as that of electroacupuncture group. The comfort needle was directly inserted into the acupoint through the adhesive pad. After the skin was broken, the tip of the needle was quickly returned to the cushion without direct contact with the skin of the patient.Low frequency rTMS treatment: the treatment regimen was the same as group (1) rTMS treatment.
Group C: electroacupuncture treatment: same group (1) electroacupuncture treatment.Pseudo-low-frequency rTMS treatment: the rTMS treatment coil was removed from the M1 area of the healthy side motor cortex of the head by 10cm, that is, the location outside the therapeutic effect area. The remaining protocol was the same as group (1) rTMS treatment.
During the experiment, subjects in the two groups should receive the necessary secondary prevention and modern rehabilitation of cerebrovascular diseases in addition to the treatment prescribed by the program.
