      摘要 目的：比较不同频率全身振动训练对脑卒中患者下肢功能的影响。 方法：将60例脑卒中患者随机分为10Hz组（n=20）、20Hz组（n=20）和30Hz组（n=20）。3组均接受常规康复训练，10Hz组在常规训练上给予10Hz全身振动训练，20Hz组在常规训练上给予20Hz全身振动训练，30Hz组在常规训练上给予30Hz全身振动训练。治疗前和治疗4周后，采用Fugl-Meyer下肢运动功能量表（Fugl-Meyer assessment scale-lower extremity，FMA-LE）、Berg平衡量表（Berg balance scale，BBS）、计时起立-行走测试（time up and go test， TUGT）、10m最大步行速度（10m maximum walking speed，MWS）进行评定。 结果：治疗4周后，3组患者的FMA-LE、BBS、TUGT和10mMWS均较治疗前显著改善（P＜0.05），30Hz组和20Hz组均显著优于10Hz组（P＜0.05），30Hz组各项指标改善最显著（P＜0.05）。 结论：3组不同频率全身振动训练均可改善脑卒中患者的下肢功能、平衡和步行能力，但30Hz全身振动训练效果最佳。

Abstract:

      Abstract Objective： To compare the effect of whole body vibration training with different frequencies on lower limb function of stroke patients. Method： A total of 60 stroke patients were randomly divided into 10Hz group（n=20），20Hz group （n=20） and 30Hz group（n=20）. Three groups received routine rehabilitation training. In addition the 10Hz group received 10Hz whole-body vibration training，20Hz group received 20Hz whole-body vibration training and the 30Hz group received 30Hz whole-body vibration training.Before and after 4 weeks training， Fugl-Meyer assessment scale-lower extremity （FMA-LE）， the Berg balance scale （BBS），timed up and go test（TUGT）and 10-meter maximum walking speed（10mMWS） were used to assess the lower limb function of patients. Result： After 4 weeks treatment，The results of FMA-LE， BBS， TUGT and 10mMWS assessment from three groups exhibited significant improvements compared with those before treatment （P＜0.05）. Moreover， the improvements of FMA-LE， BBS， TUGT and 10mMWS assessment in the 30Hz group and the 20Hz group were significantly better than those in the 10Hz group（P＜0.05）， and the improvements of various indexes in the 30Hz group were the most significant（P＜0.05）. Conclusion： Three groups of whole body vibration training with different frequencies can improve lower limb function， balance and walking ability of stroke patients，and the effect of 30Hz whole body vibration training was the most obvious.
