背景:近年来,脑机接口技术通过对动作意图的识别实现对外部设备的操控,改变了人类与计算机的交互方式,可用于脑卒中后下肢功能的治疗,为脑卒中患者康复带来了新的希望。目的:分析和总结近些年脑机接口技术在脑卒中患者下肢运动功能康复中的应用,探讨脑机接口技术在脑卒中患者下肢功能康复中的临床应用价值。方法:以“脑卒中,脑机接口,下肢”为中文检索词,在中国知网进行相关文献检索;以“stroke,brain-computer interfaces,lower extremity”为英文检索词,在PubMed数据库进行相关文献检索,检索时间范围为2014年1月至2024年6月。结果与结论:脑机接口对脑卒中患者下肢运动功能恢复具有良好的应用前景,在康复医学应用领域正在不断扩大,但其机制尚未完全阐释清楚;此外,在采集患者脑电信号方面存在一定的局限,导致脑机接口系统精确识别肢体运动的能力较差,并且目前该技术的解码方法对识别步态周期存在局限性,不能精确定位到下肢各关节与肌肉的随意运动,阻碍了脑机接口技术的应用。未来的研究应该集中在阐明脑机接口技术对脑卒中患者下肢运动功能恢复的神经机制,增强大脑运动信号提取技术和设备,为个体患者制定多模态反馈实现更有效的运动康复,以期推动脑机接口技术在下肢运动功能康复领域的进一步发展,改善患者的康复效果,提高生活质量。

We use the wide-used Einstein Toolkit to solve the Einstein constraints and then simulate the expansion of primordial black hole lattices(PBHLs) with different value of f PBH and m PBH. We find that f PBH plays an important role during the evolution of PBHLs. Since the motion of primordial black holes(PBHs) caused by the expansion of PBHLs occurs at speeds close to that of light, we expect the emission of gravitational waves(GWs) during the expansion of PBHLs. We use both analytical estimates and numerical simulations to cross check the production of GWs in expanding PBHLs.

The application of data envelopment analysis （DEA） as a multiple criteria decision making （MCDM） technique has been gaining more and more attention in recent research. In the practice of applying DEA approach, the appearance of uncertainties on input and output data of decision making unit （DMU） might make the nominal solution infeasible and lead to the efficiency scores meaningless from practical view. This paper analyzes the impact of data uncertainty on the evaluation results of DEA, and proposes several robust DEA models based on the adaptation of recently developed robust optimization approaches, which would be immune against input and output data uncertainties. The robust DEA models developed are based on input-oriented and outputoriented CCR model, respectively, when the uncertainties appear in output data and input data separately. Furthermore, the robust DEA models could deal with random symmetric uncertainty and unknown-but-bounded uncertainty, in both of which the distributions of the random data entries are permitted to be unknown. The robust DEA models are implemented in a numerical example and the efficiency scores and rankings of these models are compared. The results indicate that the robust DEA approach could be a more reliable method for efficiency evaluation and ranking in MCDM problems.
