肌电生物反馈疗法对脑卒中偏瘫患者步态影响的临床研究

Clinical research of Electromyographic biofeedback therapy on the gait of hemiplegics post stroke

目的：通过步态分析，观察肌电生物反馈疗法对偏瘫患者步态的影响。方法：将40例脑卒中偏瘫患者随机分为试验组和对照组各20例，均予常规药物及康复治疗，试验组则在常规治疗基础上给予肌电生物反馈疗法，采用三维步态分析仪器分别于治疗前、治疗4周后采集两组患者步态参数评估疗效。结果：治疗后，试验组步速、步幅、步频、步行周期、步宽、双向支撑期改善程度均显著优于对照组（P〈0.05）。结论：肌电生物反馈疗法能有效改善患者偏瘫步态，提高患者下肢运动功能及步行能力。

Objective：To explore the effects of electromyographic biofeedback therapy on the gait of patients with hemiplegia through gait analysis. Method： Forty stroke patients with hemiplegia were randomly divided into two groups： observation group （n=20） and control group （n=20）. Both groups received conventional drugs and rehabilitation therapies, the patients in observation group received electromyographic biofeedback therapy in addition. Gait parameters were collected and calculated by gait analysis system before and 4 weeks post-treatment. Result：After treatment, the param-eters of observation group , such as step length, velocity, stride length, gait cycle, stride width and double limb support phase, were more improved more significantly than control group（P〈0.05）. Conclusion：Electromyographic biofeedback therapy can effectively improve the gait of patients with hemiplegia, improve patients with lower limb motor function and walking ability.
