目的 观察下肢康复机器人辅助步行训练对脑卒中偏瘫患者运动功能及步行能力的影响。方法 2015年1月至2016年10月,60例脑卒中偏瘫患者随机分为对照组(n=30)和实验组(n=30)。两组均接受常规训练,在此基础上,对照组予人工辅助步行训练,实验组予下肢机器人辅助步行训练。训练时间均为每次30 min,每周5次,连续训练8周。训练前后分别采用Fugl-Meyer评定量表下肢部分(FMA-LE)评测下肢运动功能,机器人评估系统评定屈髋肌群肌力(FHF)和伸膝肌群肌力(FKE),6分钟步行距离和10米步行时间评定步行能力。结果 训练前,两组间一般资料及各指标无显著性差异(P>0.05)。训练后,实验组各指标均提高(t>2.274, P<0.05);除FKE外,实验组各指标均优于对照组(t>2.095, P<0.05)。结论 下肢康复机器人辅助步行训练能够有效提高脑卒中偏瘫患者的运动功能与步行能力。
Objective To explore the effect of robot-assisted gait training on the lower limb motor function and gait ability in patients with hemiplegia after stroke. Methods From January, 2015 to October 2016, 60 patients with hemiplegia after stroke were randomly divided into control group (n=30) and experimental group (n=30). Both groups received conventional rehabilitation, while the experimental group was given robot-assisted gait training and the control group was given artificial assisted gait training, 30 minutes a day, five days a week for eight weeks. They were evaluated with Fugl-Meyer Assessment-Lower Limb (FMA-LE), muscle strength of hip flexion (L-FORCE/HIP/Flex, FHF) and knee extension (L-FORCE/KNEE/Ext, FKE), Six Minutes Walking Distance and Ten Meters Walking Time before and after training. Results There was no significant difference in general data and all indexes between two groups before training (P>0.05). The scores of all the indexes improved in the experimental group after training (t>2.274, P<0.05), and all of them were better in the experimental group than in the control group (t>2.095, P<0.05), except FKE. Conclusion Robot-assisted gait training can effectively improve the lower limb motor function and gait ability of patients with hemiplegia after stroke.
