虚拟现实技术对小脑卒中患者静态平衡功能及稳定极限范围的影响

目的:观察虚拟现实技术(VR)对小脑卒中患者静态平衡功能及稳定极限范围的影响。方法:小脑卒中患者71例随机分为观察组36例和对照组35例,观察组接受VR游戏训练,对照组接受常规平衡训练。分别于训练前、训练4周后采用平衡测试仪对所有患者的身体压力中心移动面积和稳定极限进行测量。结果:治疗4周后,2组患者在睁眼和闭眼条件下的摆动有效面积、摆动路径长度、平均摆动速度值与治疗前比较均显著下降(均P0.05);2组间比较,在睁眼和闭眼条件下的平均摆动速度值无显著差异,但观察组摆动有效面积、摆动路径长度值下降更为显著(均P0.05)。治疗后,2组治LOS值均较治疗前显著提高(均P0.05),且观察组高于对照组(P0.05)。结论:基于VR的平衡训练较常规的平衡训练能更有效地改善小脑卒中患者的静态平衡功能和稳定极限范围。

Effect of virtual reality rehabilitation on static balance and limits of stability in patients with cerebellar stroke

Objective: To investigate the clinical effects of virtual reality (VR) training on static balance and limits of stability (LOS) in patients with cerebellar stroke. Methods: Seventy-one cerebellar stroke patients with balance function disorder were randomly divided into experimental group (n=36) and control group (n=35). The experimental group received balance training based on VR games, while the control group received routine balance training. Their postural stability and LOS were measured with BioRescue system before and 4 weeks after training. Results: Most of the parameters of postural stability and LOS were improved in both groups after training (P<0.05), more significantly in the experimental group than in the control group (P<0.05). Conclusion: Balance training based on VR is more effective than routine balance training on the static balance function of cerebellar stroke patients.
