摘　　要：目的:观察结合虚拟现实技术的平衡训练和传统平衡训练对脑卒中偏瘫患者平衡功能的影响方法:选取符合标准的60例脑卒中患者按照随机数字表法分成试验组(30例)和对照组(30例)。两组患者均给予常规的临床治疗、康复护理和康复训练,对照组患者在上述治疗项目外增加30min传统平衡训练,试验组患者则增加30min基于虚拟现实技术的平衡训练(3种VR游戏,每种游戏10min)。于治疗前、治疗2周后和治疗4周后分别采用Berg平衡量表(Berg balance scale,BBS)、TecnoBody(意大利产)的PK254平衡训练仪对其平衡功能进行评估。结果:治疗2周后,试验组和对照组患者的BBS评分均较治疗前有显著变化(P<0.01),但组间无显著差异(P>0.05)。两组患者应用TecnoBody的PK254平衡训练仪测试发现COP前后方向和左右方向的运动幅度的标准差、前后方向和左右方向的平均运动速度以及30s内COP的运动长度和运动面积均显著高于治疗前(P<0.05)。治疗4周后,试验组患者Berg评分显著高于对照组(P<0.001)。试验组COP参数均显著优于对照组(P<0.05)。与同组治疗后两周相比,差异具有显著性意义(P<0.05)。结论:结合虚拟现实技术的平衡训练能够改善脑卒中患者的平衡功能,且其训练效果优于传统平衡训练。Objective: To observe effects of balance training by virtual reality technology and routine balance training on the balance function in stroke patients with hemiplegia. Method: Sixty stroke patients were involved in our study and randomly divided into experimental group(30 cases) and control group(30 cases).Regular clinical treatments including rehabilitation nursing and rehabilitation training were provided for all these patients. Additional routine balance training for 30 minutes were provided for patients in the control group, and the balance training by Virtual Reality technology for 30 minutes were provided for patients in the experimental group. Before, after 2 weeks and 4 weeks training, the Berg balance scale(BBS) and the TecnoBody PK254 balance trainer were used for the evaluation of balance function of all subjects . Result: After 2 weeks training, the scores of BBS of experimental group and control group were significantly higher than that before training (P<0.01), but there was no significant difference between these two groups(P>0.05). The parameters of balance function of experimental group and control group from TecnoBody PK254 balance trainer, including the standard deviation of the forward and backward oscillation amplitude of the center of pressure(COP),the average motion velocity of forward and backward and left and right, the length and the area of the motion in 30s were significantly higher than that before training (P<0.05). After 4 weeks training, the scores of BBS of experimental group were significantly higher than that of control group (P<0.001). The parameters of COP of experimental group was significantly better than that of control group (P<0.05). Comparing the data of 2 weeks training, the difference was significant (P<0.05). Conclusion: Balance training based on virtual reality technology could effectively improve the balance function of stroke patients compared to routine balance training.
