虚拟现实平衡游戏训练对帕金森病患者平衡功能的效果

Effects of Virtual Reality Balance Game on Balance Function for Parkinson's Disease

目的：探讨虚拟现实平衡游戏训练对帕金森病患者平衡功能的影响。方法2013年10月~2016年1月，31例帕金森病患者随机分为治疗组（n=17）和对照组（n=14），治疗组采用虚拟现实平衡游戏训练，对照组进行常规平衡训练。治疗前及治疗4周后，采用Berg平衡量表（BBS）、计时“起立-行走”测试（TUGT）、改良Barthel指数（MBI）进行评定，采用平衡测试仪测量静态跌倒风险指数（SFI）、姿势稳定极限性（LOS）、动态跌倒风险指数评价（DFI）。随访患者治疗结束后6周内跌倒次数。结果治疗后，两组BBS、TUGT、SFI、LOS、DFI和MBI成绩均提高（P〈0.05），治疗组BBS评分（t=2.095）、TUGT时间（t=-2.091）、DFI （t=-2.182），LOS评分（t=2.202）、MBI评分（t=3.036）均优于对照组（P〈0.05）；BBS和MBI之间存在显著正相关（r=0.899, P〈0.001）。随访期间，治疗组平均跌倒次数少于对照组（P〈0.05）。结论虚拟现实平衡游戏训练可以促进帕金森病患者平衡功能恢复。

Objective To apply the virtual reality in balance function training for Parkinson＇s Disease （PD）. Methods From October, 2013 to January, 2016, 31 patients with balance disorders after PD were divided into two groups：the treatment group （n=17） received virtual reality balancing games training, while the control group （n=14） received routine balance training. They were assessed with Berg Balance Scale （BBS）, Timed Up and Go Test （TUGT）, static fall index （SFI）, limits of stability （LOS）, dynamic fall index （DFI） and modified Barth-el Index （MBI） before and four weeks after treatment. The frequency of falls in the next six weeks was recorded. Results The scores of BBS, TUGT, SFI, LOS, DFI and MBI improved significantly in both groups after treatment （P〈0.05）, and improved more in scores of BBS （t=2.095）, TUGT （t=-2.091）, DFI （t=-2.182）, LOS scores （t=2.202） and MBI （t=3.036） in the treatment group than in the control group （P〈0.05）. There was positive correlation between scores of BBS and MBI （r=0.899, P〈0.001）. The frequency of falls was less in the treatment group than in the control group （P〈0.05）. Conclusion Virtual reality balance training can improve the balance function for PD.
