Background:People who have had hemiplegic stoke generally move more weight to the unaffected side than the affected side, resulting in asymmetrical posture and decreased ability in walking. Objectives:This study sought to investigate the effect of inducing a weight shift to the affected side by raising the shoe height of the less affected side using an insole during the execution of treadmill training on gait ability in people with chronic stroke. Methods:The subjects were randomly assigned into two groups: insole on less affected side for execution of treadmill walking training (ILTW) group and normal treadmill training (NTW) group. The treadmill training was conducted for 30 minutes per session, 5 times a week, for 4 weeks. A gait analyzer based on body center, Functional Gait Assessment (FGA), Figure-of-Eight Walk Test (F8WT), and 6 min Walk Test (6 MWT), was measured before first intervention and after twentieth treadmill training intervention (Trial registration number is KCT0003830). Results:The results revealed statistically significant differences between the two groups in the Speed, Cadence, Stride Length/Height, Stride Length, Double Support Duration, Single Support Duration, FGA, F8WT, and 6 MWT of the gait test. In the ILTW group, statistically significant improvements were observed in the Speed, Stride Length/Height, Stride Length, Stance Phase Duration, Swing Phase Duration, Double Support Duration, Single Support Duration, FGA, F8WT, and 6 MWT after execution of training, while in the NTW group, statistically significant improvements were observed only in Speed, Cadence, FGA, F8WT, and 6 MWT. Conclusions:ILTW, more than NTW, may improve walking ability in people with chronic stroke as it increases the weight-support ratio by adjusting the shoe height of the unaffected side using an insole.

跑步机行走训练中鞋垫对受累较小侧对慢性脑卒中患者步态能力影响的初步研究

背景：患有偏瘫的人通常比患侧更多地向健侧移动，导致姿势不对称和行走能力下降。目的：本研究旨在调查在跑步机训练期间使用鞋垫提高受影响较小一侧的鞋高，从而使体重转移到受影响一侧的效果。方法：将受试者随机分为两组：小患侧鞋垫执行跑步机步行训练（ILTW）组和正常跑步机训练（NTW）组。跑步机训练每节 30 分钟，每周 5 次，持续 4 周。基于身体中心的步态分析仪，功能步态评估（FGA），八字形步行测试（F8WT），和 6 分钟步行测试 (6 MWT)，在第一次干预之前和第二十次跑步机训练干预之后进行测量（试验注册号为 KCT0003830）。结果：结果显示，两组在步态测试的速度、步频、步长/高度、步长、双支撑持续时间、单支撑持续时间、FGA、F8WT和6 MWT方面存在统计学显着差异。在 ILTW 组中，执行训练后，在速度、步幅长度/高度、步幅长度、站立阶段持续时间、摆动阶段持续时间、双支撑持续时间、单支撑持续时间、FGA、F8WT 和 6 MWT 中观察到统计学显着改善，而在 NTW 组中，仅在 Speed、Cadence、FGA、F8WT 和 6 MWT 中观察到了统计学上的显着改善。结论：ILTW，超过NTW，
