Abstract

BACKGROUND: Stroke often induces gait abnormality, such as buckling knee pattern, compromising walking ability. Previous studies indicated that an adequate trailing limb angle (TLA) is critical for recovering walking ability. OBJECTIVE: We hypothesized that correcting gait abnormality by immobilizing the knee joint using a knee orthosis (KO) would improve walking patterns and increase the TLA, and investigated whether walking training using a KO would increase the TLA in post-stroke patients. METHODS: In a randomized controlled trial, thirty-four participants were assigned to KO (walking training using a KO) and non-KO (without using a KO) groups. Twenty-nine completed the three-week gait training protocol. TLA was measured at baseline and after training. A two-way repeated ANOVA was performed to evaluate TLA increases with training type and time as test factors. A t-test compared TLA changes (ΔTLA) between the two groups. RESULTS: ANOVA showed a main effect for time (F = 64.5, p < 0.01) and interaction (F = 15.4, p < 0.01). ΔTLA was significantly higher in the KO group (14.6±5.8) than in the non-KO group (5.0±7.0, p < 0.001). CONCLUSION: Walking training using a KO may be practical and effective for increasing TLA in post-stroke patients.

使用膝关节矫形器进行训练后，偏瘫患者的后肢角度增大：随机对照试验

背景：脑卒中通常会导致膝关节屈曲等步态异常，从而影响行走能力。先前的研究表明，适当的后肢角度（TLA）对于恢复行走能力至关重要。目的：我们假设，通过使用膝关节矫形器（KO）固定膝关节来纠正步态异常，可以改善步行模式并增加 TLA，并研究使用 KO 进行步行训练是否会增加脑卒中后患者的 TLA。方法：在随机对照试验中，34 名参与者被分配到 KO 组（使用 KO 进行行走训练）和非 KO 组（不使用 KO）。29 人完成了为期三周的步态训练方案。在基线和训练后对 TLA 进行了测量。以训练类型和时间作为测试因子，采用双向重复方差分析来评估 TLA 的增加。通过 t 检验比较两组之间的 TLA 变化（ΔTLA）。结果：方差分析显示时间（F = 64.5，p < 0.01）和交互作用（F = 15.4，p < 0.01）具有主效应。KO组的ΔTLA（14.6±5.8）明显高于非KO组（5.0±7.0，P < 0.001）。结论：使用 KO 进行步行训练对于增加中风后患者的 TLA 可能是实用且有效的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
