Objective: To study the effects of virtual reality (VR) training on the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.
Methods: Thirty-five children with spastic diplegia cerebral palsy were randomly assigned to VR training group (n=19) and conventional training group (n=16). The conventional training group received conventional physical therapy and occupational therapy for three months. The VR training group received VR training and occupational therapy for three months. Grip and visual-motor integration subtests in Peabody Developmental Motor Scales-2 were used to evaluate the fine movement in patients before and after treatment. The D and E domains of the 88-item version of the Gross Motor Function Measure (GMFM-88), Modified Ashworth Scale (MAS), and Berg Balance Scale (BBS) were used to evaluate the gross movement in patients before and after treatment.
Results: Before treatment, there were no significant differences in grip, visual-motor integration, fine motor development quotient, scores of D and E domains of GMFM-88, MAS score, or BBS score between the two groups (P>0.05). After treatment, all the indices were significantly improved in the VR training group compared with the conventional training group (P<0.05).
Conclusions: VR training can effectively improve the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.
目的: 观察虚拟现实（VR）训练对痉挛型双瘫脑瘫患儿上肢精细运动和下肢粗大运动的影响。
方法: 选取痉挛型双瘫脑瘫患儿35例，随机分为VR训练组（n=19）和常规训练组（n=16），常规训练组给予3个月的常规运动疗法和作业疗法训练；VR训练组给予3个月的VR训练和作业疗法训练。采用Peabody运动发育量表的抓握、视觉-运动整合分测试对患儿治疗前后精细运动进行评价，采用88项粗大运动功能量表（GMFM-88）的D区及E区、改良Ashworth量表（MAS）、Berg平衡量表（BBS）对患儿治疗前后粗大运动进行评价。
结果: 治疗前两组患儿抓握、视觉-运动整合、精细运动发育商、GMFM-88之D区、E区评分、MAS评分、BBS评分无明显差异（P > 0.05）；治疗后，VR训练组抓握、视觉-运动整合、精细运动发育商、GMFM-88D区评分、E区评分、BBS评分、MAS评分较常规训练组明显改善（P＜0.05）。
结论: VR训练可有效提高痉挛型双瘫脑瘫患儿上肢精细运动功能和下肢粗大运动功能。
