MOTOmed下肢智能运动训练联合运动想象疗法对脑卒中偏瘫患者下肢功能、步行能力和躯干屈伸肌群肌力的影响

摘要 目的：探讨MOTOmed下肢智能运动训练联合运动想象疗法对脑卒中偏瘫患者下肢功能、步行能力和躯干屈伸肌群肌力的影响。方法：148例脑卒中偏瘫患者来源于我院2019年5月~2021年5月期间我院接收的患者，根据随机数字表法分为对照组（n=74，常规康复训练的基础上结合MOTOmed下肢智能运动训练）和研究组（n=74，对照组的基础上结合运动想象疗法）。两组均干预12周。对比两组下肢功能、步行能力和躯干屈伸肌群肌力变化。结果：两组干预12周后Fugl-Meyer运动功能量表（FMA）、Barthel指数（BI）、功能性步行能力分级量表（FAC）评分升高，且研究组高于对照组（P<0.05）。两组干预12周后步频、步速、跨步长比率升高，且研究组高于对照组（P<0.05）。两组干预12周后健侧腹直肌、竖脊肌表面肌电信号的均方根值未见明显变化，且组间同时点对比无差异（P>0.05）。两组干预12周后患侧腹直肌、竖脊肌表面肌电信号的均方根值升高，且研究组高于对照组（P<0.05）。结论：脑卒中偏瘫患者在MOTOmed下肢智能运动训练的基础上进行运动想象疗法，可促进下肢功能改善，提高步行能力，同时还可改善患侧躯干屈伸肌群肌力。

Effects of MOTOmed Lower Limb Intelligent Exercise Training Combined with Motor Imagination Therapy on Lower Limb Function, Walking Ability and Trunk Flexor and Extensor Muscle Strength in Stroke Patients with Hemiplegia

ABSTRACT Objective: To explore the effects of MOTOmed lower limb intelligent exercise training combined with motor imagination therapy on lower limb function, walking ability and trunk flexor and extensor muscle strength in stroke patients with hemiplegia. Methods: 148 stroke patients with hemiplegia who were treated in our hospital from May 2019 to May 2021 were selected. According to random number table method, they were divided into control group(n=74, combined with MOTOmed lower limb intelligent exercise training on the basis of routine rehabilitation training) and atudy group(n=74, combined with motor imagination therapy on the basis of control group). Both groups were intervened for 12 weeks. The changes of lower limb function, walking ability and trunk flexor and extensor muscle strength were compared between the two groups. Results: 12 weeks after intervention, the scores of Fugl-Meyer motor function scale (FMA), Barthel Index(BI), functional Ambulation Category (FAC) in two groups increased, and the study group was higher than the control group(P<0.05). 12 weeks after intervention, the step frequency, step speed and cross step ratio of the two groups increased, and the study group was higher than the control group (P<0.05). 12 weeks after intervention, there were no significant change in the root mean square value of surface electromyographic signals in the healthy side rectus abdominis muscle and healthy side erector spine muscle, and there was no difference between the two groups at the same time point(P>0.05). 12 weeks after intervention, the root mean square value of surface electromyographic signals in affected side rectus abdominis muscle and affected side erector spine muscle were increased, and the study group was higher than the control group(P<0.05). Conclusion: Stroke patients with hemiplegia can be rehabilitated by motor imagination therapy combined with MOTOmed lower limb intelligent exercise training, which can promote the improvement of lower limb function, improve walking ability, and improve the muscle strength of the trunk flexor and extensor muscle group on the affected side.
