本研究的目的是系统地调查不同的步行表面和鞋类特征油的能力，迅速终止步态在10名年轻人和26名老年人的影响。受试者以自选速度在三种表面上以八种随机鞋条件（标准鞋与高跟鞋、软底鞋、硬底鞋、高领鞋、喇叭底鞋、斜跟鞋和鞋底）行走：对照、不规则和潮湿。在每种条件下，受试者在8次步行试验中有3次被要求尽可能快地停止，以响应所有听觉提示。从使用两个CODA扫描仪单元收集的运动学数据计算最后一次脚接触的时间、总停止时间、停止距离、停止步数、提示后步长和步长以及总停止时的支撑长度的基础。与年轻受试者相比，老年受试者需要更多的时间和更长的距离进行最后一次足部接触，并且更频繁地被归类为使用三步或更多步停止策略。湿表面阻碍步态终止，如更大的总停止时间和停止距离所示。与标准鞋相比，软底鞋中的受试者需要更多的时间来终止步态。相比之下，高领鞋减少了油在湿表面上的总停留时间。这些研究结果表明，老年人比年轻人更难快速终止步态，并且在潮湿表面上进行具有挑战性的姿势任务时，鞋类可能会影响全身稳定性。(C)2009爱思唯尔有限公司版权所有。
The aim of this study was to systematically investigate the influence Of Various walking surfaces and footwear characteristics oil the ability to terminate gait rapidly in 10 Young and 26 older people. subjects walked at a self-selected speed in eight randomized shoe conditions (standard versus elevated heel, soft sole, hard sole, high-collar, flared sole, bevelled heel and tread sole) on three surfaces: Control, irregular and wet. In response to all audible cue, Subjects were required to Stop as quickly as possible in three out of eight walking trials in each condition. Time to last foot contact, total stopping time, stopping distance, number of steps to stop, step length and step width post-cue and base of support length at total stop were calculated from kinematic data collected Using two CODA scanner Units. The older subjects took more time and a longer distance to last foot contact and were more frequently classified as using a three or more-steps stopping strategy compared to the Young subjects. The wet surface impeded gait termination, as indicated by greater total stopping time and stopping distance. Subjects required more time to terminate gait in the soft sole shoes compared to the standard shoes. In contrast, the high-collar shoes reduced total stopping time oil the wet surface. These findings Suggest that older adults have more difficulty terminating gait rapidly than then, younger counterparts and that footwear is likely to influence whole-body stability during challenging postural tasks on wet surfaces.
