全身振动刺激对脑卒中偏瘫患者步行效率的影响

目的：观察全身振动训练对脑卒中偏瘫患者步行效率的影响。方法：脑卒中患者11例,均进行全身振动刺激,频率10Hz,振幅4mm,时间10min。振动刺激前后进行步态分析。结果：振动刺激10min后,11例患者步频、步速及患侧步长、患侧单支撑相时间、健腿摆动相时间、健侧髋关节最大屈曲角度、健患侧髋关节及膝关节最大屈曲角度、患侧踝关节最大背伸角度均较刺激前明显增加（P〈0.05）;步行周期、双支撑相时间显著缩短（P〈0.05）;健侧步长、健侧单支撑相时间、患腿摆动相时间刺激前后比较差异无统计学意义。结论：全身振动刺激可以显著改善脑卒中偏瘫患者步行时空参数,提高患者的步行能力。

Effects of whole body vibration on walking efficiency in hemiplegia patients

Objective：To investigate the effect of whole body vibration training on walking efficiency of the hemiplegia patients.Methods：Eleven patients with cerebral apoplexy accepted the whole body vibration for 10 min with vibration exciting frequency being 10 Hz,amplitude being 4mm.Gait spatial and temporal parameters containing step length,cadence,walking speed,single support phase time,swing time and double support phase with time and the largest maximum of lower joint angles were collected and calculated by gait analysis system before and after intervention.Results：After the whole body vibration stimulation,stride frequency,walking speed,walking cycle,double limb support phase,paretic swing phase,and step length were significantly increased（P〈0.05）.A significant increase in hemiplegia ankle dorsiflexion angle was associated with increased maximum hip flexion and knee flexion（P〈0.05）.Conclusion：Whole body vibration stimulation can significantly improve gait parameters and enhance lower limb walking ability of patients with stroke.
