摘要
目的 观察下肢外骨骼机器人联合踝关节康复训练对脑卒中后步行功能障碍患者步行功能的影响。 方法 将脑卒中患者45例按随机数字表法分为对照组、机器人组和联合组，每组患者15例。对照组采用常规康复训练，机器人组在常规康复训练的基础上增加下肢外骨骼机器人辅助的步行训练；联合组每日常规康复训练20 min，然后每日增加下肢外骨骼机器人辅助的步行训练10 min，和踝关节康复训练10 min。3组患者均每日训练1次，每周训练5 d，连续训练3周。治疗前和治疗3周后(治疗后)采用Fugl-Meyer运动功能量表评定下肢部分(FMA-LE)、Holden功能性步行分级(FAC)、步速和步频来评价3组患者的步行功能。 结果 治疗后，3组患者的FMA-LE评分、FAC分级、步速和步频均较组内治疗前均显著改善，差异均有统计学意义(P<0.05)。治疗后，机器人组的FMA-LE评分、步速和步频均显著优于对照组治疗后(P<0.05)，而联合组治疗后的FMA-LE评分、步速和步频分别为(22.67±1.63)分、(0.65±0.05)m/s和(80.80±4.28)步/min，均显著优于对照组和机器人组治疗后，差异均有统计学意义(P<0.05)。 结论 下肢外骨骼机器人联合踝关节康复训练可显著改善脑卒中后步行功能障碍患者的步行功能。 Objective To observe any effect of using a lower limb exoskeleton robot during ankle rehabilitation training on the walking ability of stroke survivors. Methods Forty-five persons with cerebral apoplexy were randomly divided into a control group, a robot group and a combination group, each of 15. In addition to routine rehabilitation training 5 days a week for 3 weeks, the robot group additionally trained for 10 minutes assisted by a lower limb exoskeleton. The combined group joined that training and additionally undertook 10 minutes of ankle rehabilitation training. Before and after the experiment all of the participants were evaluated using the Fugl-Meyer lower extremity scale (FMA-LE), the Holden functional walking scale (FAC), and for walking speed and step frequency. Results After treatment, significant improvement was observed in the average FMA-LE score, FAC grade, walking speed and step frequency in all 3 groups. The robot group′s average FMA-LE score, walking speed and step frequency were then significantly better than those of the control group (P<0.05). Moreover, the average FMA-LE score, step speed and step frequency of the combined group after treatment were (22.67±1.63) min, (0.65±0.05) m/s and (80.80±4.28) steps /min, respectively, significantly better than the other two groups (P<0.05). Conclusion Using an exoskeleton robot combined with ankle rehabilitation training can significantly improve the walking of stroke survivors.
