运动想象联合生物反馈治疗对脑卒中患者上肢功能障碍的疗效观察

The efficacy of movement imagination with biofeedback for improving upper extremity dysfunction after stroke

目的探讨运动想象联合生物反馈治疗对脑卒中患者上肢功能障碍疗效的影响。方法将80例脑卒中患者按随机数字表法分为运动想象组（单纯采用运动想象治疗）和联合治疗组（采用运动想象联合生物反馈治疗），每组40例。在治疗前和治疗6周后，分别采用简化Fugl一Meyer上肢评分法评定上肢运动功能，采用改良Barthel指数（MBI）量表评定日常生活活动（ADL）能力并测定患侧腕指背伸时的肌电均值。结果治疗6周后，2组腕指背伸时的肌电均值、简化Fugl—Meyer上肢功能评分、MBI指数均较治疗前改善（运动想象组为P〈0．05；联合治疗组为P〈0．01）；而且联合治疗组各项评定指标改善较运动想象组更为明显，差异有统计学意义（P〈0．05）。结论运动想象联合生物反馈治疗能较好地改善脑卒中患者的上肢功能障碍，治疗作用优于单一的运动想象疗法。

Objective To study the efficacy of movement imagination combined with biofeedback for stroke patients with upper extremity dysfunction. Methods Eighty stroke survivors were recruited and randomly divided into a movement imagination group （n = 40） and a movement imagination combined with biofeedback group （n = 40）. Their EMG mean values during wrist dorsiflexion were amplified and calculated. Fugl-Meyer upper extremity function scores （FMAs） and the modified Barthl index （MBI） were recorded before and after 6 weeks of treatment. Results After 6 weeks of treatment the two groups had significantly higher mean EMG values, FMA scores and MBI scores, but the effects in the combination group were significantly better than those in the simple movement imagination group. Conclusion Movement imagination can be made more effective by combining it with biofeedback for promoting the recovery of stroke patients with upper extremity dysfunction.
