混合现实技术下运动训练对脑卒中偏瘫患者的干预效果

Intervention effect of mixed reality technology exercise training on stroke patients with hemiplegia under hybrid reality technology

目的探讨混合现实技术下运动训练对脑卒中偏瘫患者的干预效果。方法选取西安医学院第一附属医院康复医学科2019年1月至2022年12月收治的265例脑卒中偏瘫患者,按照随机数字表法将其分为研究组(132例)和对照组(133例)。对照组采用常规治疗及肢体功能运动训练,研究组在对照组基础上采用混合现实技术下运动训练,两组均干预3个月。比较两组干预前后下肢运动功能、平衡功能、血清生化指标及大脑神经功能。结果干预过程中,研究组2例剔除(1例配合度较差,1例病情不稳),对照组4例剔除(3例自身原因退出,1例配合度较差),最终研究组、对照组分别纳入130例、129例。干预后,两组下肢Fugl-Meyer评定量表(FMA)评分、Berg平衡量表(BBS)评分和血清神经生长因子(NGF)、脑源性神经细胞营养因子(BDNF)水平均高于干预前,δ/α功率比(DAR)、脑对称指数(BSI)值低于干预前,且研究组FMA评分、BBS评分及血清NGF、BDNF水平均高于对照组,DAR、BSI值均低于对照组(P<0.05)。结论混合现实技术下运动训练可提高脑卒中偏瘫患者下肢运动功能、平衡能力,促进脑功能重塑。

Objective To explore the intervention effect of exercise training on stroke patients with hemiplegia under hybrid reality technology.Methods A total of 265 stroke patients with hemiplegia admitted to the Department of Rehabilitation Medicine,the First Affiliated Hospital of Xi’an Medical University from January 2019 to December 2022 were selected,they were divided into study group(132 cases)and control group(133 cases)by random number table method.The control group received routine treatment and limb functional exercise training,while the study group received mixed reality technology exercise training on the basis of the control group.Both groups were intervened for three months.The lower limb motor function,balance function,serum biochemical indicators,and brain nerve function were compared between the two groups before and after intervention.Results During the intervention process,two cases were excluded in the study group(one case with poor cooperation,one case with unstable condition),and four cases were excluded in the control group(three cases withdrew for their own reasons,one case with poor cooperation).Finally,130 cases were included in the study group and 129 cases in the control group,respectively.After intervention,the scores of lower limb Fugl-Meyer assessment scale(FMA),Berg balance scale(BBS),serum nerve growth factor(NGF),and brain-derived neurotrophic factor(BDNF)in the two groups were higher than those before intervention,and the values ofδ/αpower ratio(DAR)and brain symmetry index(BSI)were lower than those before intervention,and the FMA score,BBS score,and serum NGF and BDNF levels in the study group were higher than those in the control group,and the values of DAR and BSI were lower than those in the control group(P<0.05).Conclusion Mixed reality technology exercise training can improve lower limb motor function and balance ability in stroke patients with hemiplegia,and promote brain function remodeling.
