步态不对称损害神经系统患者的日常生活活动，增加他们跌倒的风险，并导致合并症。需要可获得的长期康复方法来帮助神经系统患者恢复对称的行走模式。本研究旨在确定被动单侧髋关节外装是否可以改变诱导的不对称步行步态模式。我们假设在健康的年轻人中，被动式髋关节外装可以减少初次和后分离带跑步机行走的后遗症。我们将15名健康的年轻人平均分为三个实验组，每个实验组完成基线试验，每组有不同干预措施的适应期，以及适应后试验。为了分离外露服的贡献，我们将适应外露服和裂带跑步机的组（Exo-Sb）与适应外露服（Exo-only）和只适应裂带跑步机（Sb-only）的组进行了比较。使用3 × 5混合方差分析分析了5个时间点（基线、早期和晚期适应以及早期和晚期适应）的自变量步长、站立时间和摇摆时间对称性。我们发现步长、站姿时间和摆动时间对称性具有显著的交互作用和时间效应。与基线相比，Sb-only在早期适应时增加了步长不对称性（p < 0.0001），并且在适应后早期与基线相比增加了不对称性（p < 0.0001）。与基线相比，Exo-only在早期适应时增加了步长不对称性（与Sb-only相反）（p = 0.0392），但对参与者的影响不足以导致后效。Exo-Sb与Sb-only在相同方向上产生了相似的步长不对称变化（p = 0.0014）。然而，与单用sb相比，适应后早期与基线之间没有显著的后效（p = 0.0885）。该被动式外服成功地消除了Exo-Sb中分裂带跑步机引起的步长不对称后效。这些结果支持了被动式外套改变行走步态模式的能力。在线版本包含补充材料，可在10.1186/s12984-023-01212-w获得。
Asymmetric walking gait impairs activities of daily living in neurological patient populations, increases their fall risk, and leads to comorbidities. Accessible, long-term rehabilitation methods are needed to help neurological patients restore symmetrical walking patterns. This study aimed to determine if a passive unilateral hip exosuit can modify an induced asymmetric walking gait pattern. We hypothesized that a passive hip exosuit would diminish initial- and post-split-belt treadmill walking after-effects in healthy young adults. We divided 15 healthy young adults evenly between three experimental groups that each completed a baseline trial, an adaptation period with different interventions for each group, and a post-adaptation trial. To isolate the contribution of the exosuit we compared a group adapting to the exosuit and split-belt treadmill (Exo-Sb) to groups adapting to exosuit-only (Exo-only) and split-belt only (Sb-only) conditions. The independent variables step length, stance time, and swing time symmetry were analyzed across five timepoints (baseline, early- and late adaptation, and early- and late post-adaptation) using a 3 × 5 mixed ANOVA. We found significant interaction and time effects on step length, stance time and swing time symmetry. Sb-only produced increased step length asymmetry at early adaptation compared to baseline (p < 0.0001) and an after-effect with increased asymmetry at early post-adaptation compared to baseline (p < 0.0001). Exo-only increased step length asymmetry (in the opposite direction as Sb-only) at early adaptation compared to baseline (p = 0.0392) but did not influence the participants sufficiently to result in a post-effect. Exo-Sb produced similar changes in step length asymmetry in the same direction as Sb-only (p = 0.0014). However, in contrast to Sb-only there was no significant after-effect between early post-adaptation and baseline (p = 0.0885). The passive exosuit successfully diminished asymmetrical step length after-effects induced by the split-belt treadmill in Exo-Sb. These results support the passive exosuit’s ability to alter walking gait patterns. The online version contains supplementary material available at 10.1186/s12984-023-01212-w.
