The gait characteristics of blind travelers can provide information about their mobility skills. Previous attempts at measuring these characteristics have suffered because they either do not provide continuous monitoring or allow usage outside a laboratory setting. A new instrument has been developed to overcome these problems. The instrument allows continuous monitoring of interankle distance during walking. Records of interankle distance were analyzed to determine maximum interankle distance/step, step time, and cadence. With this system, gait parameters revealed differences between two groups of travelers (blind and blindfolded) and changes over a series of four trials on turns, straightaways, and over the whole route. This suggests the system is useful as an assessment device both for research and for rehabilitation training.
盲人行走者的步态特征能够提供有关他们移动技能的信息。以往测量这些特征的尝试存在缺陷，因为它们要么无法提供持续监测，要么不允许在实验室环境之外使用。一种新仪器已被开发出来以克服这些问题。该仪器能够在行走过程中持续监测两脚踝之间的距离。对两脚踝之间距离的记录进行分析，以确定最大两脚踝间距/步幅、步幅时间和步频。通过这个系统，步态参数揭示了两组行走者（盲人组和蒙眼组）之间的差异，以及在转弯、直道和整个路线上的一系列四次试验中的变化。这表明该系统作为一种评估工具，对研究和康复训练都很有用。
