目的观察虚拟现实训练对痉挛型脑瘫患儿下肢粗大运动功能及步行速度的影响。方法选取2013年3月-2015年10月在该院就诊的痉挛型双瘫患儿35例为研究对象,随机分为实验组(19例)和对照组(16例)。对照组行常规运动疗法和作业疗法训练;实验组行虚拟现实训练和作业疗法训练。治疗前后,采用GMFM-88粗大运动功能量表的D区及E区、改良Ashworth量表(MAS)、Berg平衡量表(BBS)对患儿粗大运动进行评价,采用步态周期、步行速度评价患儿步行功能。结果治疗后,两组GMFM-88D区评分、E区评分、BBS评分、步行速度均显著高于组内治疗前(P<0.05),实验组GMFM-88D区评分、E区评分、BBS评分、步行速度高于对照组(均P<0.05);两组MAS评分、步态周期均低于治疗前(P<0.05),实验组MAS评分、步态周期低于对照组(P<0.05)。结论虚拟现实训练可有效提高痉挛型双瘫患儿下肢粗大运动功能及步行功能。 Objective To observe the effects of virtual reality training on gross motor function and walking speed of lower extremities in children with spastic cerebral palsy. Methods Totally 35 children with spastic diplegia treated in our hospital from March 2013 to October 2015 were randomly divided into experimental group (n = 19) and control group (n = 16). The control group received routine exercise therapy and homework therapy training. The experimental group received virtual reality training and homework therapy training. Before and after treatment, the gross movement of the children was assessed by using the GMFM-88 Gross Motor Function Scale D and E, Modified Ashworth Scale (MAS) and Berg Balance Scale (BBS). The gait cycle and walking speed Children walking function. Results After treatment, the score of GMFM-88D, the score of E, the score of BBS and the speed of walking in the two groups were significantly higher than those before treatment (P <0.05). The GMFM-88D score, E score, BBS score, The walking speed was higher than that of the control group (all P <0.05). The MAS score and gait cycle in both groups were lower than those before treatment (P <0.05). The MAS score and gait cycle in the experimental group were lower than those in the control group (P <0.05). Conclusion Virtual Reality Training can effectively improve the motor function and walking function of lower extremities in children with spastic diplegia.
