Robot-assisted gait training improves the pelvis control and walking function of hemiplegic stroke survivors

目的观察机器人辅助步行训练对脑卒中后偏瘫患者骨盆运动能力和步行功能的影响。方法选取嘉兴市第二医院2016年5月至2017年2月脑卒中后偏瘫患者30例,按随机数字表法分为治疗组(15例)和对照组(15例)。2组患者均接受常规临床药物和常规康复治疗,治疗组患者在以上治疗方案的基础上增加步行辅助机器人训练,每日1次,每次20min。于治疗前、治疗8周后(治疗后)对2组患者进行骨盆运动评估、10m最大步行速度(MWS)测试、移动能力评定(TUGT)和功能性步行分级(FAC)评估。结果治疗后,2组患者的侧向位移、高度位移、旋转、侧倾角度与组内治疗前比较,差异均有统计学意义(P<0.05),且治疗组上述各项指标均优于对照组治疗后,差异均有统计学意义(P<0.05)。治疗后,2组患者的MWS、TUGT、FAC与组内治疗前比较,差异均有统计学意义(P<0.05),且治疗组治疗后的MWS和TUGT分别为(38.7±5.2)m/min和(21.5±10.7)s,亦显著优于对照组治疗后,差异均有统计学意义(P<0.05)。结论机器人辅助步行训练可更有效地改善脑卒中偏瘫患者的骨盆控制能力和步行功能。

ObjectiveTo explore the effect of robot-assisted gait training on pelvis kinematics and the walking function of hemiplegic stroke survivors.MethodsThirty stroke survivors with hemiplegia were randomly divided into a treatment group and a control group,each of 15.Both groups were given routine clinical medication and rehabilitation training,while the treatment group was additionally provided with 20 minutes of robot-assisted gait training a day,6 d/wk for 8 weeks.Before and after the treatment,all of the patients′pelvis kinematics were assessed using 10 m walking speed(MWS),the timed up and go test(TUGT)and functional ambulation categorization(FAC).ResultsBefore the treatment there were no significant differences between the two group in any of the measurements.After the treatment,significant improvement was observed in both groups in the vertical displacement and rotation and tilt angles of the pelvis while walking,with significantly more improvement in the treatment group than in the control group.There was also significant improvement in the average walking speed,TUGT time and FAC score of both groups,with significantly more improvement in the treatment group.ConclusionRobot-assisted gait training can significantly improve the pelvis control and walking ability of hemiplegic stroke survivors.
