摘　　要：目的观察并探讨基于运动表象的脑机接口(BCI)训练对亚急性期脑卒中偏瘫患者手功能康复的疗效。方法2020年6月至2021年12月,郑州大学第五附属医院康复医学科亚急性期脑卒中偏瘫患者40例随机数字表法分为对照组(n=20)和试验组(n=20)。两组均予药物治疗和常规综合康复,对照组采用手部康复机器人训练,试验组采用基于运动表象的BCI训练,共4周。治疗前后,采用Fugl-Meyer评定量表上肢部分(FMA-UE)、改良Barthel指数、改良Ashworth量表进行评定,表面肌电图检测患侧指浅屈肌、指伸肌和拇短展肌在最大等长收缩状态下的积分肌电值(iEMG)。结果对照组脱落2例,试验组脱落1例。治疗后,两组各项指标均改善(t>2.322,Z>2.631,P<0.05);除FMAUE腕评分外,其他指标试验组优于对照组(t>2.227,Z>2.078,P<0.05)。结论基于运动表象的BCI训练能有效改善亚急性期脑卒中偏瘫患者的手功能和日常生活活动能力。Objective To observe the effect of brain-computer interface(BCI)training based on motor imagery on hand function in hemiplegic patients with subacute stroke.Methods From June,2020 to December,2021,40 patients with hemiplegia in subacute stroke from Department of Rehabilitation Medicine,Fifth Affiliated Hospital of Zhengzhou University were divided into control group(n=20)and experimental group(n=20)using random number table.Both groups accepted medication and routine comprehensive rehabilitation,while the control group accepted hand rehabilitation robot training,and the experimental group accepted the robot training using motor imagery-based BCI,for four weeks.They were assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),modified Barthel Index,modified Ashworth scale,and measured integrated electromyogram of the superficial finger flexors,finger extensors and short thumb extensors of the affected forearm during maximum isometric voluntary contraction with surface electromyography.Results Two patients in the control group and one in the experimental group dropped off.All the indexes improved in both groups after treatment(t>2.322,Z>2.631,P<0.05),and they were better in the experimental group than in the control group(t>2.227,Z>2.078,P<0.05),except the FMA-UE score of wrist.Conclusion Motor imagery-based BCI training is more effective on hand function and activities of daily living in hemiplegic patients with subacute stroke.
