虚拟现实康复机器人对早期脑卒中患者步行功能的疗效观察

Effect of training with a robot-virtual reality system compared with a robot alone on the gait performance of individuals after sub-acute stroke

目的：探讨虚拟现实技术结合康复机器人训练对早期脑卒中偏瘫患者步行功能的治疗效果。方法：42例早期脑卒中偏瘫患者随机分为虚拟现实康复机器人组（实验组）和康复机器人组（对照组），每组各21例。2组均进行常规康复治疗基础上，实验组进行虚拟现实技术结合康复机器人训练，而对照组只进行传统的康复机器人训练，均为30min／次，5次／周，共进行8周。治疗前后采用Fugl-Meyer下肢评定表（FMA-LE）、10m步行能力测试（10MW），起立-步行测试（TUG）和6分钟步行能力测试（6MWT）进行评定。结果：治疗8周后，2组患者的FMA下肢评分、10MW、TUG和6MWT均较治疗前明显提高（P＜0．05），实验组除FMA下肢评分外，其它各项评定与对照组比较均具有显著差异（ P＜0．01）。结论：应用虚拟现实技术结合康复机器人步态训练对早期脑卒中偏瘫患者进行功能训练能提高患者的步行功能。

Objective：To investigate whether the training of gait to locomotion was greater using a virtual environment coupled with a robot or with the robot alone .Methods：42 subjects with sub -acute stroke participated in this study .They had conducted the rehabilita-tion therapy, and randomly assigned to experiment group （21 subjected） trained with the robot virtual reality system and the control group （21 subjects） trained with the robot alone, the 8 week training protocol：30 min per session, and 5 sessions per week.Outcome measures were included Fugl-Meyer of lower extremity （FMA-LE）, 10-meter walk test （10MW）, time up and go test （TUG）, and 6-minute walk test （6MWT）.Results：After 8-week training, the FMA-LE, 10MW, TUG and 6MWT were all significant difference （P〈0.05） compared with pre-treatment in two groups.Significant changes （P＆lt;0.01） in velocity and distance walked were demonstrated for the group trained with the robotic device coupled with the VR than training with the robot alone , expect the FMA-LE score.Conclusion：The study demonstrated that gait training of individuals with sub -acute hemiparesis using a robotic device coupled with virtual reality improved walking ability than robot training alone .
