基于沉浸式VR技术的下肢运动训练对脑卒中患者下肢功能的临床疗效

Clinical efficacy of lower limb exercise training based on immersive VR technology on lower limb function in stroke patients

目的:探讨沉浸式虚拟现实技术(VR)结合下肢运动训练对脑卒中患者下肢功能的临床疗效及生活质量的影响。方法:选取2022年12月至2023年11月在永康市第一人民医院康复医学科接受住院康复治疗的初发脑卒中患者为研究对象,将符合纳入标准的60例患者按照随机数字表法分为对照组和VR组,每组30例。两组患者均接受常规药物和康复治疗,对照组在此基础上增加下肢运动训练,VR组在下肢运动训练时结合VR康复训练。每天训练20 min,每周5次,共3周。通过下肢Fugl-Meyer运动功能量表(FMA-LE)、功能性步行分级(FAC)、Berg平衡量表(BBS)、Barthel指数(BI),来评估两组患者治疗前后的下肢功能和生活能力变化。结果:治疗前,两组患者基线值及量表评分比较差异无统计学意义(P>0.05),训练3周后,两组患者FMA-LE、FAC、BBS及BI评分较组内治疗前均显著改善,差异有统计学意义(P<0.05)。治疗结束后,VR组FMA-LE、FAC、BBS及BI评分均显著优于对照组,差异均有统计学意义(P<0.05)。结论:结合沉浸式VR技术的下肢运动训练能明显改善脑卒中偏瘫患者的下肢功能和生活质量。

Objective:To explore the clinical efficacy of immersive virtual reality(VR)combined with lower limb exercise training on the lower limb function of stroke patients and their quality of life.Methods:Patients with initial stroke who received inpatient rehabilitation treatment at the Rehabilitation Department of the First People’s Hospital of Yongkang from December 2022 to November 2023 were selected as the study subjects.A total of 60 patients who met the inclusion criteria were randomly assigned to the control group(n=30)and VR group(n=30).Both groups received routine drugs and routine rehabilitation treatment.On this basis,the control group was supplemented with the lower limb exercise training and the VR group was combined with VR technology during the exercise training,with a duration of 20 minutes per day,5 times a week for 3 weeks.The lower limb motor function,walking ability and daily living ability of the patients were evaluated by the Fugl-Meyer assessment of the lower extremities(FMA-LE),functional ambulation category(FAC),the Berg balance scale(BBS)and the Barthel index(BI).Results:Prior to the treatment,there was no notable discrepancy in the baseline value or scale scores between the two groups.Over 3 weeks of training,both groups improved significantly in the scores of FMA-LE,FAC,BBS and BI,compared with those before treatment,showing statistical difference(P<0.05).Ater the treatment,the FMA-LE,FAC,BBS,and BI scores in the VR group significantly improved,compared with those in the control group,showing statistical difference(P<0.05).Conclusion:The combination of immersive VR technology with exercise training can significantly improve the lower limb function and quality of life in stroke hemiplegic patients.
