Stroke is a leading cause of death and disability worldwide. To find ways to reduce behavioral disabilities, researchers study animal models. By targeting ST-36 () and SP-9 (), this study investigated the effects of traditional acupuncture and electroacupuncture (EA) on motor behavior in gerbils following global cerebral ischemia.
Thirty-six male gerbils were randomly assigned to 6 groups ( = 6 in each): control (C); sham-surgical (S); ischemia (I); acupuncture (Ac); EA (Ea); and sham-EA (SEa). The animals were habituated in an activity cage (AC) 72 hours before surgery. After induction of global ischemia, the Ac, Ea, and SEa groups received bilateral stimulation at ST-36 and SP-9. In the Ea group, an alternating electrical current was used. The animals were tested in the AC 4 days after surgery, and the results were analyzed by Kruskal-Wallis, followed by Dunn's test.
Statistical analysis revealed increased distance traveled and sensors triggered by the I, Ea, and SEa groups, compared to the C, Ac, and S groups. The animals' movement tracks had a similar pattern between the I and Ea groups, with increased exploration along the walls of the AC. Meanwhile, the Ac, S, and SEa groups explored the AC similarly to the C group.
These findings suggest that acupuncture may normalize motor behavior in gerbils with ischemia and could be a promising treatment for stroke-induced motor deficits.
中风是全球范围内导致死亡和残疾的主要原因。为了找到减少行为残疾的方法,研究人员对动物模型进行了研究。本研究通过针对足三里(ST-36)和足临泣(SP-9),探讨了传统针刺和电针(EA)对全脑缺血后沙鼠运动行为的影响。
36只雄性沙鼠随机分为6组(每组n = 6):对照组(C);假手术组(S);缺血组(I);针刺组(Ac);电针组(Ea);假电针组(SEa)。在手术前72小时,将动物饲养在活动笼(AC)中使其适应环境。诱导全脑缺血后,Ac、Ea和SEa组在双侧足三里和足临泣接受刺激。在Ea组中,使用交流电。术后4天在活动笼中对动物进行测试,结果采用Kruskal-Wallis检验分析,随后进行Dunn检验。
统计分析显示,与C、Ac和S组相比,I、Ea和SEa组的移动距离增加,触发的传感器更多。I组和Ea组动物的运动轨迹模式相似,沿着活动笼壁的探索增加。同时,Ac、S和SEa组对活动笼的探索与C组相似。
这些发现表明,针刺可能使缺血沙鼠的运动行为恢复正常,可能是中风所致运动功能障碍的一种有前景的治疗方法。
