摘要:

文题释义:
经颅直流电刺激:是一种利用恒定、低强度直流电(1.0-2.0 mA)调节皮质神经元活动的非入侵式脑神经调控技术。阳极经颅直流电刺激可促进神经元去极化产生兴奋,阴极经颅直流电刺激可导致神经元超极化产生抑制;阳极经颅直流电刺激能够提升人体在平衡任务中的运动表现,改善人体的平衡能力。
动态平衡能力:人体在运动过程中及特定的运动情境下,受外力作用时自动调整并维持身体姿势的能力。

背景:高精度经颅直流电刺激在促进认知和运动行为提升方面有巨大潜力,其可提升人体的静态平衡能力。
目的:探究高精度经颅直流电刺激对人体动态平衡能力的影响。
方法:招募沈阳体育学院36名健康学生为试验对象,男24名,女12名,随机数字表法分3组,分别接受电流强度为0(假刺激),1,2 mA的阳极高精度经颅直流电刺激,刺激20 min。刺激前及刺激后即刻、30 min,测试受试者的动态平衡能力。研究已经通过沈阳体育学院研究伦理委员会审查,伦理字[2020]12号。
结果与结论:①受试者接受1 mA阳极高精度经颅直流电刺激后即刻、30 min的双足动态稳定指数、右足动态稳定指数均显著降低(P < 0.05),刺激后30 min的偏移距离显著缩短(P < 0.05);②受试者接受2 mA阳极高精度经颅直流电刺激后30 min的双足动态稳定指数、右足动态稳定指数均显著降低(P < 0.05),刺激后即刻、30 min的偏移距离显著缩短(P < 0.05);③不同刺激强度的阳极高精度经颅直流电刺激改善人体动态平衡的效果无差异(P > 0.05);④结果表明,高精度经颅直流电刺激可以短暂提升人体的动态平衡能力,不仅可以促进双足站立和单足站立的动态稳定性,还可以促进主动运动过程中步态的稳定控制。

Abstract: BACKGROUND: High-definition transcranial direct current stimulation has great potential in promoting the improvement of cognition and motor behavior, which can improve the body’s static balance ability. 
OBJECTIVE: To investigate the effect of high-definition transcranial direct current stimulation on the body’s dynamic balance. 
METHODS: A total of 36 healthy students from Shenyang Sport University were recruited as test subjects, including 24 males and 12 females. They were divided into three groups by a random number table method, followed by anodic high-definition transcranial direct current stimulation with different current intensities of 0  (sham stimulation), 1, and 2 mA for 20 minutes. The dynamic balance ability was tested before stimulation and immediately and 30 minutes after stimulation. The study protocol was approved by the Institutional Review Board of Shenyang Sport University (approval No. [2020]12). 
RESULTS AND CONCLUSION: The subject’s bipedal dynamic stability index and right-foot dynamic stability index were significantly reduced immediately and 30 minutes after 1 mA stimulation (P < 0.05). The offset distance was significantly shortened at 30 minutes after 1 mA stimulation (P < 0.05). The subject’s bipedal dynamic stability index and right-foot dynamic stability index were significantly reduced 30 minutes after 2 mA stimulation (P < 0.05). The offset distance was significantly shortened immediately and 30 minutes after 2 mA stimulation (P < 0.05). Anodic high-definition transcranial direct current stimulation with different current intensities showed no different effects in improving the dynamic balance of the human body (P > 0.05). To conclude, high-definition transcranial direct current stimulation can temporarily improve the dynamic balance ability. It cannot only increase the dynamic stability when standing on single and both feet, but also promote gait stability during active exercises.
