肌电生物反馈治疗仪联合双侧运动训练对卒中后上肢运动功能障碍患者的影响

Effect of Myoelectric Biofeedback Therapeutic Apparatus Combined with Bilateral Exercise Training on Patients with Upper Limb Motor Dysfunction after Stroke

目的:探讨肌电生物反馈治疗仪联合双侧运动训练对卒中后上肢运动功能障碍患者的影响。方法:选取2022年2月—2023年1月江门市人民医院收治的62例卒中后上肢运动功能障碍患者作为研究对象。根据随机数表法将其分为对照组和观察组,各31例。对照组给予双侧运动训练,观察组给予肌电生物反馈治疗仪联合双侧运动训练。比较两组干预前、干预2周、干预4周时上肢运动功能、日常生活能力、腕伸肌积分肌电值(integrated electromyography,iEMG),干预前后运动功能分级。结果:干预2周、4周,两组上肢Fugl-Meyer运动功能评估量表(Fugl-Meyer assessment scale,FMAS)评分、Barthel指数(Barthel index,BI)评分均升高,观察组两组上肢FMAS评分、BI评分均高于对照组,差异有统计学意义(P<0.05)。干预后,观察组Ⅲ级、Ⅳ级率均低于对照组,Ⅴ级率高于对照组,差异有统计学意义(P<0.05)。干预2周、4周,两组腕伸肌iEMG均升高,观察组腕伸肌iEMG均高于对照组,差异有统计学意义(P<0.05)。结论:卒中后上肢运动功能障碍者接受肌电生物反馈治疗仪联合双侧运动训练,可进一步提升其上肢运动功能,进而改善其日常生活能力。

Objective:To explore the effect of myoelectric biofeedback therapeutic apparatus combined with bilateral exercise training on patients with upper limb motor dysfunction after stroke.Method:A total of 62 patients with upper limb motor dysfunction after stroke treated in Jiangmen People's Hospital from February 2022 to January 2023 were selected as the study objects.They were divided into control group and observation group according to random number table method,with 31 cases in each group.The control group was given bilateral exercise training,and the observation group was given myoelectric biofeedback therapeutic apparatus combined with bilateral exercise training.The upper limb motor function,daily living ability,wrist extensor integrated electromyography(iEMG)before,at 2 weeks and 4 weeks of intervention,and the motor function grading before and after intervention were compared between the two groups.Result:At 2 and 4 weeks of intervention,the scores of upper limb Fugl-Meyer assessment scale(FMAS)and Barthel index(BI)in both groups were increased,the upper limb FMAS scores and BI scores in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).After intervention,the rate of grade Ⅲ and Ⅳin the observation group was lower than that in the control group,and the rate of grade Ⅴ was higher than that in the control group,the differences were statistically significant(P<0.05).At 2 weeks and 4 weeks of intervention,the wrist extensor iEMG was increased in both groups,and the wrist extensor iEMG in observation group was higher than that in control group,the differences were statistically significant(P<0.05).Conclusion:The patients with upper limb motor dysfunction after stroke can further enhance their upper limb motor function and improve their ability of daily living by receiving myoelectric biofeedback therapeutic apparatus combined with bilateral exercise training.
