目的:以非受累侧前运动皮质区(premotor cortex,PMC)为刺激靶点,比较不同治疗时程的重复经颅磁刺激(repeated transcranial magnetic stimulation,rTMS)对脑卒中患者上肢运动功能及脑功能连接的影响。方法:将60例缺血性脑卒中后上肢运...目的:以非受累侧前运动皮质区(premotor cortex,PMC)为刺激靶点,比较不同治疗时程的重复经颅磁刺激(repeated transcranial magnetic stimulation,rTMS)对脑卒中患者上肢运动功能及脑功能连接的影响。方法:将60例缺血性脑卒中后上肢运动功能障碍患者随机分到6周rTMS组、4周rTMS组和2周r TMS组以及对照组,每组15例。在治疗前后采用上肢Brunnstrom分期、Fugl-Meyer运动功能评分上肢部分(Fugl-Meyer assessment of upper extremity,FMA-UE)和Wolf运动功能评分(Wolf motor function test,WMFT)进行行为学评定,另外以非受累侧PMC为种子点采用静息态功能磁共振成像(resting state functional magnetic resonance imaging,rs-fMRI)进行功能连接分析。结果:治疗后,2周rTMS组的FMA-UE和WMFT的评分与4周及6周rTMS组间有显著性差异(P<0.05),但4周rTMS组的FMA-UE和WMFT的评分与6周rTMS组间无显著性差异(P>0.05)。非受累侧PMC区为种子点的功能连接分析显示,rTMS治疗后非受累侧PMC与同侧中央前回、对侧颞中回和楔前叶功能连接增强(P<0.05)。结论:研究结果表明,以非受累侧半球PMC为靶点的低频rTMS治疗可有效促进偏瘫上肢运动功能的恢复,其中与2周rTMS干预和6周rTMS干预相比,4周rTMS干预具有最佳的时间-效益比,这可能与其增强双侧半球间、非受累半球内皮质-皮质间的功能连接有关。展开更多
