摘　　要：目的:探讨功能性电刺激同步结合虚拟现实技术治疗脑卒中偏瘫患者下肢运动功能障碍的临床疗效。方法:将58例脑卒中后导致足下垂或足内翻的患者随机分为常规治疗组(对照组28例)和功能性电刺激结合虚拟现实技术治疗组(治疗组30例)。在治疗前、治疗4周后对所有患者进行肌张力、下肢运动、平衡功能及步行功能的评定,分别对患者进行肌张力评定(改良后Ashworth分级评定)、Fugl-Meyer下肢功能评定、"站起—走"计时测试评定、10m最大步行速度测试。结果:2组患者一般资料及治疗前各项评定结果差异无显著性意义;治疗4周后与治疗前比较,两组患者下肢运动功能、平衡功能、步行速度均有明显改善(P<0.01);治疗4周后2组比较,治疗组疗效更为显著(P<0.05),与对照组比较,治疗组患者的肌张力未见明显增高(P>0.05)。结论:功能性电刺激同步结合虚拟现实技术能改善脑卒中足下垂、足内翻患者的下肢运动功能、平衡功能及步行速度;与传统训练方法比较更利于促进患侧下肢运动功能的逐渐恢复,达到安全、省时、高效,值得在临床推广应用。Objective： To observe the clinical effect of functional electrical stimulation synctlrOnlzed wltn vlrtual reaJaty technology on lower limbs dysfunction of patients after stroke. Method：Fifty-eight stroke subjects with foot drop or strephenopodia were randomly divided into routine treatment group （the control group, n=28） and functional electrical stimulation synchronized with virtual reality technology treatment group （the therapy group, n=30）. Before treatment and at 4 weeks after treatment, muscle tone, lower limbs＇ motor function, balance function and walking function were assessed by modified Ashworth scales（MAS）, modified Fugl-Meyer lower limbs scales, the time “up ＆ go” as well as 10m maximum walking speed（10m MWS）. Result： Before treatment no significant difference was found in baseline data of each group. After 4 weeks＇ treatment, there were significant differences on improving lower limbs＇ motor function, balance function and walking speed of all patients （P〈0.01） and the therapy group had better effect（P〈0.05）. But there was no signif-icant difference on improving patients＇ muscle tone between the therapy group and the control group after 4 weeks＇ treatment（P〉O.05）.Conclusion： Functional electrical stimulation synchronized with virtual reality technology can improve lower limbs＇ motor function, balance function and walking speed of patients with foot drop and strephenopodia after stroke. It is a safe, time saving and high efficiency method for promoting the recovery of lower limbs＇ motor function gradually compared with the traditional training method and is worthy to widespread it＇s clinical application.
