虚拟现实联合跑台训练对脑卒中患者平衡功能和步行能力的效果

Effect of virtual reality treadmill training on balance and gait in stroke patients

目的 探讨虚拟现实联合跑台训练对脑卒中患者平衡功能和步行能力的影响。方法 2022年3月至2023年3月首都医科大学附属北京天坛医院康复科脑卒中患者40例,随机分为对照组和试验组,每组20例。两组均参加常规康复训练,对照组在普通跑台上进行步行训练,试验组在具有虚拟现实的跑台上进行步行训练,共2周。治疗前后采用Berg平衡量表(BBS)、计时起立-行走测试(TUGT)、包络椭圆面积、压力中心(COP)运动平均速度以及步长、步幅、步宽评价平衡功能和步行能力。结果 治疗后,两组BBS评分和TUGT时间均明显改善(|t|> 3.508, P <0.01),试验组明显优于对照组(|t|> 3.019,P <0.01);两组包络椭圆面积、COP运动平均速度、步宽无明显变化(P> 0.05);试验组步长和步幅明显改善(|t|> 4.008, P <0.01)。结论 虚拟现实联合跑台训练可以改善脑卒中患者的平衡功能和步行能力。

Objective To explore the effect of virtual reality treadmill training on balance and gait in stroke patients.Methods From March,2022,to March,2023,40 stroke patients in Beijing Tiantan Hospital,Capital Medical University were randomly divided into control group(n=20)and experimental group(n=20).Both groups received routine rehabilitation training.The control group received ordinary treadmill walking training,and the experimental group received treadmill walking training with virtual reality,for two weeks.They were assessed with Berg Balance Scale(BBS)and Timed Up and Go Test(TUGT),and the envelope ellipse area,center of pressure(COP)average speed of movement,step length,stride length and stride width were compared between two groups before and after treatment.Results After treatment,the scores of BBS and time of TUGT improved in both groups(|t|>3.508,P<0.01),and they were better in the experimental group than in the control group(|t|>3.019,P<0.01);there was no significant difference in the envelope ellipse area,COP average speed,and stride width between two groups(P>0.05);however,the step length and stride width improved in the experimental group(|t|>4.008,P<0.01).Conclusion Treadmill training with virtual reality can improve the balance and walking ability of stroke patients.
