可穿戴式智能足底压力视觉反馈技术对脑卒中患者平衡功能的影响

目的:研究可穿戴式智能足底压力视觉反馈技术对脑卒中患者平衡功能的影响,并探讨此技术在临床平衡功能训练中的应用方式和价值。方法:选择病程为8个月内的脑卒中患者30例,随机分配到试验组和对照组,每组15例。对照组接受常规平衡训练,试验组在可穿戴式智能足底压力视觉反馈技术配合下进行平衡训练,每次30min,每周5次,共训练4周。比较训练前及训练4周后两组患者的平衡功能评分,包括Berg平衡量表(BBS),"起立—行走"计时测试(TUG)和采用可穿戴式智能足底压力视觉反馈鞋垫记录的睁眼和闭眼静态平衡率,以评估训练的有效性和对照组与试验组间训练效果的差异。结果:训练前两组患者的一般资料、BBS及TUG评分和静态平衡率均无显著性差异(P>0.05);训练后,试验组和对照组患者各观察指标与训练前相比均有显著改善(P<0.05)。试验组的训练后与训练前各平衡功能评分差值与对照组相较更大,且有显著性差异(P<0.05)。结论:应用可穿戴式智能足底压力视觉反馈技术进行平衡功能训练可以改善偏瘫患者的平衡功能,且较常规方法更有效。

Effects of wearable intelligent plantar pressure visual feedback technique in balance training for post-stroke patients: a randomized controlled trial

Abstract Objective: To observe the effect of wearable intelligent plantar pressure visual feedback technique in the balance training for post-stroke patients. To discuss the application method and value of this technique in clinical balance training as well. Method: Thirty hemiplegic patients with stroke less than 8 months were randomly allocated to experimental(n=15) or control group(n=15). The control group received the traditional balance training, while the experimental group participated in the balance training with the wearable intelligent plantar pressure visual feedback technique, for 30min once daily,5 days per week for 4 weeks. BBS score,TUG score and balance ratio were evaluated twice: one day before and 4 weeks after training to compare the difference in efficacy between two groups. Result: Before training, there were no significant differences in general information, BBS score, TUG score and balance ratio between two groups (P>0.05). After training, all the parameters show significant differences in both groups (P<0.01). In addition, the difference between post-training and pre-training of the groups were significant(P<0.05) with the bigger difference in the experimental group. Conclusion: Applying wearable intelligent plantar pressure visual feedback technique in balance training can improve the balance function of stroke patients and was more effective than the traditional training.
