摘  要:目的 观察足下垂刺激仪对脑卒中足下垂患者下肢运动功能的影响.方法 共选取30例脑卒中后伴下肢运动功能障碍患者,在常规药物及康复干预基础上,于患者步行过程中使用足下垂刺激仪对患侧下肢腓总神经、胫前肌进行电刺激.本研究采用自身对照方式,分别检测给予电刺激及不给予电刺激时患者下肢运动功能变化情况,具体检测指标包括平地10 m步行速度、爬10阶楼梯速度、步态不对称指数(GAI)、非偏瘫侧摆动时间变异性(STV)、生理消耗指数(PCI)及踝关节活动度(ROM)等.结果 入选患者步行过程中给予电刺激时,发现其10m步行速度[(17.15±3.03)m/s]、爬10阶楼梯速度[(5.90 ±0.55) m/s]、GAI(32.70 ±6.75)、STV(60.50±16.09)、PCI[(0.34 ±2.32)t/m]及踝关节ROM[背伸(15.00±13.03)°,屈曲(35.67±9.04)°,内翻(41.10±11.11)°]均较不给予电刺激时检查结果显著改善(P<0.05);而踝关节外翻角度在给予电刺激后无明显变化(P>0.05).结论 足下垂刺激仪能有效改善脑卒中患者足下垂,增加行走时踝关节背伸角度,减小内翻角度,对提高患者下肢运动功能具有重要促进作用.Objective To observe the effects of treatment with a foot drop stimulator on the lower limb motor function of patients with foot drop after stroke.Methods Thirty stroke survivors with lower limb motor function problems received stimulation of the peroneal nerve and the tibialis anterior muscle while walking.They also received conventional drugs and rehabilitation therapy.Lower limb motor function was assessed on the basis of walking velocity,stair climbing velocity,the gait asymmetry index (GAI),swing time variability (STV),a physiologic cost index (PCI) and ankle range of motion (ROM).Each was compared with the value when the same patient was not given foot drop stimulation.Results No significant difference was found in ankle eversion whether stimulation was given or not,but all the other measures were significantly improved after stimulation with 10 meters walking velocity at (17.15 ± 3.03)m/s,10 stairs climbing velocity at (5.90 ± 0.55)m/s,GAI of (32.70 ± 6.75),STV of (60.50 ± 16.09) and PCI of [(0.34 ±2.32)t/m],as well as ankle dorsiflexion of (15.00 ±13.03) °,plantarflexion of (35.67 ± 9.04) o and varus of (41.10 ± 11.11) ° respectively.Conclusions Foot drop stimulation can effectively improve ankle dorsiflexion and reduce the varus while walking for stroke patients.This gives better lower limb motor function for patients with foot drop.
