摘　　要：目的:探究虚拟情景互动训练对老年人跌倒风险的干预效果。方法:40例受试者随机分为对照组和训练组,各20例。对照组受试者仅进行预防跌倒的健康教育干预,训练组受试者在健康教育的同时进行虚拟情景互动训练3个月。训练前后2组受试者均进行动态步态指数(DGI)、记时起立行走测试(TUGT)和修订版跌倒功效量表(MFES)评价,并检测血清脑源性神经营养因子(BDNF)水平。结果:训练3个月后,训练组DGI和MFES评分均较训练前显著提高(P<0.01),并且均明显高于对照组水平(均P<0.05);训练组TUGT和总分较训练前均显著降低(均P<0.05),并且均明显低于照组水平(均P<0.05);训练组血清BDNF水平较训练前及对照组均显著升高(均P<0.01)。结论:虚拟情景互动训练能够改善老年人认知老化,提高步态稳定性和身体运动功能,促进大脑BDNF分泌,对降低老年人跌倒风险具有良好的干预效果。Objective:To investigate the intervention effect of virtual situational interactive training system reducing the falling risk in older adults.Methods:Forty older adults were randomly divided into control group and training group,20 cases in each group.The control group received education of falls prevention program.The training group received education of falls prevention program combined with virtual situational interactive training for three months.The dynamic gait index(DGI),time up and go test(TUGT),modified falls efficacy scale(MFES)and serum BDNF were recorded and evaluated before and after intervention,respectively.Results:After virtual svirtual situational interactive training,the DGI and serum BDNF of the older adults in training group were enhanced,and the results of TUGT and MFES were significantly improved as compared with those before intervention and the control group(all P<0.05),respectively.Conclusion:Virtual situational situational interactive training system can improve cognitive aging,gait stability,body movement function and BDNF levels of the older adults,and has a good intervention effect on reducing the falling risk of older adults.
