      摘要 目的：探讨基于交互式视觉反馈的姿势控制训练对脑梗死Pusher综合征患者静、动态平衡功能的影响。 方法：36例Pusher综合征患者根据随机数字表分配为试验组和对照组，各18例。对照组采用常规姿势镜反馈下的平衡训练；试验组采用基于交互式视觉反馈的姿势控制训练。治疗前后采用Burke倾斜量表（BLS）、Berg平衡量表（BBS）及Biodex平衡仪中的姿势稳定测试（PST）进行评定。 结果：治疗6周后，①倾斜程度：两组BLS评分均较治疗前明显降低（P＜0.05），且试验组较对照组明显降低（P＜0.05），差异有显著性意义（P＜0.05）；②静态平衡：两组睁、闭眼下PST中总稳定值（OSI）、前后值（API）及左右值（MLI）均较治疗前明显降低（P＜0.05），且试验组较对照组明显降低（P＜0.05），差异有显著性意义（P＜0.05）；③动态平衡：两组BBS评分均较治疗前明显提高（P＜0.05），且试验组优于对照组（P＜0.05），差异有显著性意义（P＜0.05）。 结论：基于交互式视觉反馈的姿势控制训练可明显提高脑梗死Pusher综合征患者静、动态平衡功能，且效果优于常规姿势镜反馈下平衡训练。

Abstract:

      Abstract Objective: To investigate the effects of interactive visual feedback-based postural control training on balance of cerebral infarction patients with Pusher syndrome. Method: Thirty-six cerebral infarction patients with Pusher syndrome were randomly assigned into the experimental group (n=18) and the control group (n=18). The control group received common balance training with posture mirror feedback, while the experimental group received interactive visual feedback-based postural control training. The Burke lateropulsion scale (BLS), the postural stability test (PST) of the Biodex balance system and the Berg balance scale (BBS) were the outcome measures. All patients were evaluated pre- and post-treatment. Result: After treatment for 6 weeks, a comparison of pre- and post-treatment assessment results revealed the following significant changes for both groups: ①Severity of pusher syndrome: decrease in scores of the BLS (P＜0.05); ②Static balance: decrease in the data of PST, including overall stability index (OSI), anterior posterior index (API) and medial lateral index (MLI) (P＜0.05); ③Dynamic balance: increase in scores of the BBS (P＜0.05). Furthermore, the experimental group produced significantly better outcomes in the improvement of balance ability compared with the control group (P＜0.05). Conclusion: The interactive visual feedback-based postural control training is more effective in enhancing static and dynamic balance ability of cerebral infarction patients with Pusher syndrome compared with the common balance training with mirror.
