操作性肌电生物反馈疗法对脑卒中患者运动功能恢复的DTI研究

目的:结合核磁共振弥散张量成像(DTI)技术探讨操作性肌电生物反馈疗法改善脑卒中患者运动功能的可能机制.方法:脑卒中患者37例,随机分为康复组19例和对照组18例,均给予常规药物和康复治疗,康复组辅以操作性肌电生物反馈治疗4周.治疗前、治疗4周后采用Fugl-Meyer运动功能评定量表(FMA)进行评估,同时进行DTI...

A DTI Study of Effectiveness of Operant-conditioning Electromyography Biofeedback Therapy in Improving Motor Function of Patients with Stroke

Objective:To investigate the effects of EMG biofeedback therapy on stroke patients by means of MRI.Methods:Thirty-seven patients with stroke were randomly divided into treatment and control groups.All patients received standard rehabilitation program.The patients in the treatment group have received additional EMG biofeedback treatment along with the conventional rehabilitation intervention.All the patients have been evaluated before the treatment and 4 weeks after the treatment using Fugl-Meyer motor assessment(FMA) for motor function.MR-DTI was used to measure the Fractional Anisotropy(FA) values in the brain white matter fibre bundles.Results:EMG biofeedback therapy treatment significantly improved the FMI scores and FA value relative to those in the control group.The change in FMI scores had a positive correlation with the increase of FA value.Conclusion:Operant-conditioning EMG-BFT contributes to the reorganization of brain structures and function by repeating directional induction.
