目的:通过Meta分析系统性评估间歇性Theta刺激改善脑卒中患者下肢运动功能、平衡功能以及日常活动能力的效果。方法:检索Cochrane Library、Scopus、PubMed、Embase、ProQuest、Web of Science、中国知网、中国生物医学、维普和万方数据...目的:通过Meta分析系统性评估间歇性Theta刺激改善脑卒中患者下肢运动功能、平衡功能以及日常活动能力的效果。方法:检索Cochrane Library、Scopus、PubMed、Embase、ProQuest、Web of Science、中国知网、中国生物医学、维普和万方数据库,选择各数据库建库至2024年11月期间间歇性Theta刺激治疗脑卒中的随机对照试验。其中,试验组接受小脑/M1区间歇性Theta刺激,对照组进行常规康复治疗。采用RevMan 5.3和Stata 16.0进行Meta分析。结果:共纳入12篇文献,444例患者。Meta分析表明,间歇性Theta刺激有助于提高脑卒中患者下肢Fugl-Meyer量表评分[WMD=2.87,95%CI(1.77,3.98),P<0.00001]、Berg平衡量表评分[WMD=5.79,95%CI(3.80,7.79),P<0.00001]以及改良Barthel指数[WMD=6.32,95%CI(4.02,8.44),P<0.00001]。亚组分析结果显示,相较于600脉冲刺激,1200脉冲刺激更有利于改善下肢Fugl-Meyer量表评分[WMD=4.31,95%CI(2.91,5.71),P<0.00001]、Berg平衡量表评分[WMD=8.12,95%CI(5.27,10.98),P<0.00001]和改良Barthel指数[WMD=8.50,95%CI(6.55,10.45),P<0.00001]。结论:间歇性Theta刺激能够提高脑卒中患者的下肢运动能力、平衡功能及日常生活能力评分。其中,1200脉冲间歇性Theta刺激在改善下肢运动能力、平衡功能和日常生活能力方面,可能具有更大益处。展开更多
