丰富平衡训练对脑卒中偏瘫患者平衡功能的影响

目的:探讨丰富平衡训练对脑卒中偏瘫患者平衡功能的影响。方法:选取40例符合入选标准的脑卒中偏瘫患者,随机分为2组各20例,常规组予以常规传统平衡训练,丰富组在常规训练的基础上,利用虚拟现实技术,模拟丰富环境,并结合任务导向性项目进行平衡训练;在治疗前、4周训练结束时评价2组患者Berg平衡量表评分(BBS)、平衡仪站立位睁眼静态平衡测试、"起立-行走"计时(TUGT)。结果:治疗4周后,2组BBS评分均较治疗前明显提高(P0.05,0.01),且丰富组更优于常规组(P0.05);2组TUGT评分、运动轨迹长度及外周面积均较治疗前明显减少(P0.05,0.01),且丰富组更低于常规组(P0.05)。结论:丰富平衡训练对卒中后偏瘫患者的平衡功能有很好的改善作用。

Effects of enriched balance training on balance function in stroke patients with hemiplegia

Objective: To investigate effects of enriched balance training on balance function in stroke patients with hemiplegia. Methods: Forty stroke patients with hemiplegia with balance dysfunction were enrolled. They were divided into a normal balance training group and an enriched balance training group (n=20 each). The normal balance training group only received conventional balance treatment. On the basis of conventional balance treatment, the patients in enriched balance training group received the task orientation program for balance training in enriched environment by using virtual reality technology. Berg balance scale (BBS) score, Timed Up and Go Test (TUGT) and the test of the standing balance in eye-opened condition by using the balance assessment equipment were used to evaluate the patients of both groups before and 4 weeks after treatment. Results: Before treatment, there were no significant differences in various indicators between the two groups (P>0.05). After treatment, all the indicators including BBS scores were significantly increased, and the sway length, area in eye-opened condition and TUGT were significantly reduced in both groups as compared with those before treatment (P<0.05 or P<0.01). The improving degrees of BBS scores, the sway length in eye-opened condition, the area in eye-opened condition and TUGT in the enriched balance training group were all better than those in the normal balance training group (P<0.05). Conclusion: Enriched balance training could obviously improve the balance function in stroke patients with hemiplegia.
