Abstract：
Post-stroke gait asymmetry leads to inefficient gait and a higher fall risk, often causing limited home and community ambulation. Two types of treadmills are typically used for training focused on symmetry: split-belt and single belt treadmills, but there is no consensus on which treadmill is superior to improve gait symmetry in individuals with stroke. To comprehensively determine which intervention is superior, we considered multiple spatial and temporal gait parameters (step length, stride time, swing time, and stance time) and their symmetries. Ten individuals with stroke underwent a single session of split-belt treadmill training and single belt treadmill training on separate days. The changes in step length, stride time, swing time, stance time and their respective symmetries were compared to investigate which training improves both spatiotemporal gait parameters and symmetries immediately after the intervention and after 5 min of rest. Both types of treadmill training immediately increased gait velocity (0.08 m/s faster) and shorter step length (4.15 cm longer). However, split-belt treadmill training was more effective at improving step length symmetry (improved by 27.3%) without sacrificing gait velocity or step length. However, this step length symmetry effect diminished after a 5-min rest period. Split-belt treadmill training may have some advantages over single belt treadmill training, when targeting step length symmetry. Future research should focus on comparing the long-term effects of these two types of training and examining the duration of the observed effects to provide clinically applicable information.
摘要：
中风后步态不对称导致步态效率低下，跌倒风险更高，经常导致有限的家庭和社区步行。两种类型的跑步机通常用于集中于对称的训练：分裂带跑步机和单带跑步机，但对于哪种跑步机能更好地改善卒中患者的步态对称性，目前尚无共识。综合判断哪种干预措施更优,我们考虑了多个时空步态参数(步长，跨步时间,摆动时间,和站立时间)和它们的对称性。10名中风患者在不同的日子接受了一次分裂皮带跑步机训练和单皮带跑步机训练。步长的变化，跨步时间,摆动时间,比较了站立时间和各自的对称性，以调查哪种训练在干预后和休息5分钟后立即改善了时空步态参数和对称性。两种类型的跑步机训练都立即增加了步态速度（快0.08m/s）和更短的步长（长4.15cm）。然而,在不牺牲步态速度或步长的情况下，分裂皮带跑步机训练在改善步长对称性（提高了27.3％）方面更有效。然而,这种步长对称效应在5分钟的休息期后减弱。分式皮带跑步机训练可能比单式皮带跑步机训练有一些优势，当瞄准步长对称时。未来的研究应侧重于比较这两种类型的训练的长期效果，并检查观察到的效果的持续时间，以提供临床适用的信息。
