摘要
目的:探讨虚拟现实技术(virtual reality,VR)对脑卒中偏瘫患者平衡稳定性的影响。方法:采用随机数字表法,将40例脑卒中偏瘫患者随机分为试验组和对照组各20例,对照组给予传统平衡康复训练,试验组给予虚拟现实技术训练治疗。观察分析治疗前、治疗4周后部分核心肌群表面肌电图(surface electromyography,sEMG)、Berg平衡量表(Berg balance scale,BBS)、Dynstable系统中的“Assessment”(评测)程序稳定极限(limits of stability)、稳定时间(time to stability)。结果:治疗前两组受试者一般资料及s EMG、BBS、稳定极限、稳定时间无显著性差异(P>0.05)。治疗4周后,两组BBS较治疗前显著改善(P<0.05),且试验组优于对照组(P<0.05);竖脊肌、多裂肌以及腹直肌的s EMG、稳定极限及稳定时间均较治疗前改善(P<0.05),且试验组优于对照组(P<0.05)。结论:虚拟现实技术可更有效地改善脑卒中偏瘫患者平衡稳定性。
Objective:To explore the effect of virtual reality on balance control and standing stability of stroke patients with hemiplegia.Method:Based on random number method,40 stroke patients with hemiplegia were randomly divided into test group and control group,with 20 cases in each group.The test group was treated the virtual reality training while the control group was given the traditional balance rehabilitation treatment.The surface electromyography(sEMG)of some core muscles,Berg Balance Scale(BBS),and the limits of stability and time to stability of“Assessment”program in Dynstable system were observed and analyzed before and 4 weeks after the training.Result:There were no significant differences in general data,sEMG,BBS,limits of stability and time to stability between the two groups before training(P>0.05).After 4 weeks of training,BBS were significantly improved in both groups(P<0.05),and the test group was better than the control group(P<0.05).The sEMG of target muscles including erector spinae,multifidi and rectus abdominis,and limits of stability and time to stability were all improved in comparison to before training(P<0.05),and the test group improved more than the control group(P<0.05).Conclusion:Virtual reality technology can effectively improve balance stability in stroke patients with hemiplegia.
