虚拟现实技术联合下肢康复机器人训练对缺血性脑卒中患者下肢功能及平衡能力影响的研究

目的:探讨虚拟现实技术联合下肢康复机器人训练对缺血性脑卒中患者下肢功能及平衡能力的影响。方法:收集60例缺血性脑卒中下肢功能障碍患者,随机分为对照组和观察组各30例,对照组进行常规康复训练和Lokomat下肢机器人训练,观察组在此基础上再联合虚拟现实技术,治疗前和治疗4周后分别对2组患者进行Berg平衡量表(BBS)、Fugl-Meyer下肢运动功能量表(FMA-LE)、功能性步行量表(FAC)评定。结果:治疗4周后,2组患者BBS和FMA-LE评分较治疗前均明显提高(均P<0.01),且观察组以上评分均更高于对照组(均P<0.05);2组患者FAC分级较治疗前均明显改善(均P<0.01),且观察组分级较对照组改善更显著(P<0.05)。结论:虚拟现实技术联合下肢康复机器人训练能改善缺血性脑卒中患者的下肢功能及平衡能力。

Influence of virtual reality combined with lower limb rehabilitation robot training on lower limb function and balance ability in patients with ischemic stroke

Objective: To explore the effect of virtual reality combined with lower limb rehabilitation robot training on lower limb function and balance ability in patients with ischemic stroke. Methods: Sixty patients with lower extremity dysfunction of ischemic stroke were collected and divided into a control group and a treatment group (n=30 each). The control group received conventional rehabilitation training and Lokomat lower limb robot training, and the treatment group were given conventional rehabilitation training and Lokomat lower limb robot training combined with virtual reality as well. Berg Balance Scale (BBS) score, Fugl-Meyer Assessment Lower Extremity (FMA-LE) score, and Functional Ambulation Category (FAC) level were recorded before and after 4 weeks of treatment. Results: After 4 weeks of treatment, BBS and FMA-LE scores of patients in both groups were significantly higher than those before treatment (all P<0.01), and those in the treatment group were significantly higher than those in the control group (all P<0.05). The FAC grades of patients in both groups were significantly improved as compared with those before treatment (all P<0.01), and the grades in the treatment group were more significantly improved than those in the control group (P<0.05). Conclusion: Virtual reality combined with lower limb rehabilitation robot training can improve the lower limb function and balance ability of the patients with ischemic stroke.
