摘　　要：目的探讨下肢区域性振动刺激对脑卒中偏瘫患者步行速度与稳定性的作用。方法脑卒中偏瘫患者26例,坐位下接受频率16 Hz、振幅4 mm的下肢区域性振动刺激10 min,评定振动前后小腿三头肌张力(改良Ashworth分级,MAS)、3 m计时起立行走时间(TUGT)和10 m最大步行速度(MWST),分析干预前后MAS、TUGT、10 m MWST差异性。结果振动后与振动前评定数值比较发现振动后小腿三头肌张力MAS评分没有显著性变化(P>0.05),TUGT及10 m MWST均增加,差异有统计学意义(P<0.05)。结论下肢区域性振动刺激能够提高脑卒中患者即刻的步行速度及稳定性,改善步行功能,而对缓解小腿三头肌痉挛没有显著作用。Objective To determine the effects of regional vibration stimulation （RVS） on walking speed and stability in the elderly patients with stroke. Methods Twenty-six patients with hemiplegie post-stroke were enrolled in this study. All of them received lower limbs RVS （ 16 Hz, 4 ram） on the bilateral foot soles for 10 rain in sitting position. The modified Ashworth scale （MAS） score for the triceps surae muscle tonus, Timed up and go test （TUGT） and 10 m maximum walking speed test （MWST） were perfonued before and after the vibration. Results After RVS, both TUGT and 10 m MWST showed significant improvements （P〈0. 05）. However, the MAS score did not have significant change （P〉0. 05）. Conclusions The lower limbs RVS on the bilateral foot soles in sitting position could increase the stability and velocity of locomotion in post-stroke hemiplegia. But, the muscle tonus on the calf could not be improved significantly.
