目的 观察下肢康复机器人训练对脑卒中偏瘫患者下肢运动功能的影响。 方法 采用随机数字表法将40例脑卒中偏瘫患者（病程<12周）分为治疗组及对照组。对照组患者给予常规康复干预，治疗组患者在常规康复干预基础上辅以下肢康复机器人步行训练，每天治疗1次，共连续治疗6周。于治疗前、治疗6周后分别采用简式Fugl-Meyer运动功能量表（FMA）下肢评分及上田敏式偏瘫下肢功能量表对2组患者下肢运动功能进行评定，同时采用功能性步行分级（FAC）评价2组患者步行能力改善情况。 结果 治疗前2组患者下肢FMA评分、上田敏式分级及FAC评分组间差异均统计学意义（P>0.05）；治疗6周后发现2组患者下肢FMA评分、上田敏式分级及FAC评分均较治疗前明显改善（P<0.05），并且治疗组患者下肢FMA评分［(28.14±3.37)分］、上田敏式分级［(10.29±1.69)级］及FAC评分［(3.86±0.77)分］均显著优于对照组水平［分别为（24.62±3.69）分、（8.85±1.73）级和（2.92±0.86）分］，组间差异均具有统计学意义（P<0.05）。 结论 在常规康复干预基础上辅以下肢康复机器人步行训练，能进一步提高脑卒中偏瘫患者下肢运动功能，该疗法值得临床推广、应用。 Objective To evaluate the effects of robot-assisted gait training on the lower limb motor functions of in hemiplegic stroke patients. Methods Forty stroke patients with hemiplegia were randomly divided into a treatment group and a control group. Both groups were treated with routine rehabilitation therapies for 60 min daily in 6 weeks. The patients in the treatment group were given robot-assisted gait training for 30 min daily for 6 weeks. The lower limb part of Fugl-Meyer assessment (FMA), the Ueda Satoshi standardized hemiplegic function scale and the functional ambulation categories (FAC) were used to evaluate the lower limb motor function before and after the six-weeks of therapies. Results There were no significant difference between the two groups before treatment with regard to all the three assessment measurements. After 6 weeks of treatment, both groups significantly improved in terms of the scores with FMA, the grade of Ueda Satoshi standardized hemiplegic function scale and the FAC (P<0.05). But the treatment group had significantly greater improvement than the control group (P<0.05). Conclusions The robot-assisted gait training can supplement the routine rehabilitation therapies in improving lower limb motor function in stroke patients
