核心肌群训练结合虚拟现实技术对脑卒中病人平衡能力的临床研究

目的：观察核心肌群训练结合虚拟现实(virtual reality, VR)技术对脑卒中病人下肢平衡能力的影响。方法：将72例脑卒中病人随机分为核心肌群训练组及VR组，每组36例。VR组采用常规康复训练配合VR训练，核心肌群训练组在VR组基础上增加核心肌群训练。于治疗前、治疗4周后、治疗8周后分别采用Berg平衡量表(BBS)、B-PHY型平衡能力检查训练仪、日常生活活动量表(ADL)对2组病人的BBS评分、ADL评分、压力中心(COP)椭圆面积进行分析比较。结果：治疗4周后，2组病人BBS评分、COP椭圆面积、ADL评分较治疗前均改善(P<0.05);治疗8周后，2组病人BBS评分、ADL评分均较组内治疗前、治疗4周后有显著改善(P<0.05～P<0.01);核心肌群组睁眼及闭眼时测定COP椭圆面积较同组治疗前、治疗4周后均有显著改善(P<0.05);组间同时期BBS评分、COP椭圆面积及ADL评分比较，核心肌群组均显著优于VR组(P<0.05～P<0.01)。结论：核心肌群训练结合VR技术可明显改善脑卒中病人平衡能力，提高生活质量，且简单易行。

Clinical study on balance ability of patients with cerebral apoplexy by core muscle training combined with virtual reality technology

ObjectiveTo observe the effect of core muscle training combined with virtual reality (VR) technology on lower limb balance ability of patients with cerebral apoplexy.MethodsA total of 72 patients with cerebral apoplexy were randomly divided into core muscles training group and VR technology group, 36 cases in each group.The VR group adopted routine rehabilitation training combined with VR training, and the core muscle training group added core muscle training on the basis of the VR group.Berg balance scale (BBS), B-PHY balance function examination and training instrument, and activities of daily living (ADL) were used to assess the two groups before treatment, 4 weeks and 8 weeks after treatment.ResultsAfter 4 weeks of treatment, BBS score, COP elliptical area and ADL score of patients in both groups were improved compared with those before treatment (P < 0.05).After 8 weeks of treatment, BBS scores and ADL scores of patients in both groups were significantly improved compared with those before and after 4 weeks of treatment (P < 0.05 to P < 0.01).Compared with the same group before treatment and after 4 weeks of treatment, the area of COP ellipse measured when the core muscle group opened and closed eyes was significantly improved (P < 0.05).In the same period, the BBS score, COP elliptical area and ADL score of the core muscle group were significantly better than those of the VR technology group (P < 0.05 to P < 0.01).ConclusionsCore muscle training combined with VR technology can significantly improve the balance ability of patients with cerebral apoplexy, improve the quality of life, and is simple and easy to operate.
