目的 探讨兼有视觉运动反馈脑机接口技术的运动想象训练在脑卒中患者康复中的长期应用效果,为脑卒中患者的康复治疗提供依据.方法 选择2022 年8 月—2023 年8 月在安徽医科大学第二附属医院康复医学科住院的45 例脑卒中偏瘫患者作为研究对象.随机分为A组(对照)、B组(运动想象)、C组(脑机接口),均采用住院(2~3 周)、回家(2~3周)、住院(2~3 周)的模式进行康复.住院期间,A组仅采用常规康复治疗;B组在常规康复基础上嘱患者本人自行进行运动想象反馈治疗;C组在常规康复基础上使用脑机接口技术进行干预.比较三组患者治疗前后Fugl-Meyer下肢运动功能评定量表(Fugl-Meyer Assessment-Lower Extremity,FMA-LE)、改良Ashworth分级(Modified Ashworth Scale,MAS)、徒手肌力检测(Manual Muscle Test,MMT).结果 治疗前,各组FMA-LE、MAS、MMT比较,差异均无统计学意义(P>0.05).治疗后,各组观察指标均优于治疗前(P<0.05).组间比较结果显示:第一疗程后,C组FMA-LE优于对照组(P<0.05),MMT优于其他两组(P<0.05),第三疗程后,B组MMT优于对照组(P<0.05).结论 脑机接口技术在脑卒中下肢功能障碍患者中的应用能有效改善患者的下肢功能.
Objective To investigate the long-term application effect of motor imagination training based on visual motor feedback brain-computer interface technology in the rehabilitation of stroke patients,and to provide evidence for the rehabilitation treatment of stroke patients.Methods From August 2022 to August 2023,45 patients with stroke hemiplegia who were hospitalized in Rehabilitation Medicine Department of the Second Affiliated Hospital of Anhui Medical University were selected.They were randomly divided into A group(control),B group(motor imagination)and C group(brain computer interface),and were treated in hospital(2-3 weeks),home(2-3 weeks)and hospital(2-3 weeks).During hospitalization,group A only received conventional rehabilitation treatment.On the basis of routine rehabilitation,patients in group B were instructed to perform motor imagination feedback therapy by themselves.In group C,brain-computer interface technology was used to intervene on the basis of routine rehabilitation.Fugl-Meyer Lower Limb Motor Function Rating Scale(FMA-LE),Modified Ashworth scale(MAS)and manual muscle strength test(MMT)were compared before and after treatment in three groups.Results Before treatment,there was no significant difference in FMA-LE,MAS and MMT among all groups(P>0.05).After treatment,the observation indexes in all groups were better than before treatment(P<0.05).The results of inter-group comparison showed as follows:After the first course of treatment,FMA-LE and MMT in group C were better than those in the control group(P<0.05),and MMT in group B was better than those in the other two groups(P<0.05).Conclusion The application of brain-computer interface technology in stroke patients with lower limb dysfunction can effectively improve the lower limb function.
