Locomotion of children and adults with a visual impairment (ages 1-44, n = 28) was compared to that of age-related individuals with normal vision (n = 60). Participants walked barefoot at preferred speed while their gait was recorded by a Vicon(®) system. Walking speed, heading angle, step frequency, stride length, step width, stance phase duration and double support time were determined. Differences between groups, relationships with age and possible interaction effects were investigated. With increasing age overall improvements in gait parameters are observed. Differences between groups were a slower walking speed, a shorter stride length, a prolonged duration of stance and of double support in the individuals with a visual impairment. These may be considered either as adaptations to balance problems or as strategies to allow to foot to probe the ground.
比较了 28 名视力障碍儿童和成年人（1-44 岁）与 60 名年龄匹配的正常视力个体的运动方式。参与者赤脚以自然速度行走，同时使用 Vicon（®）系统记录他们的步态。确定了行走速度、朝向角度、步频、步长、步宽、支撑阶段持续时间和双支撑时间。研究了组间差异、与年龄的关系和可能的交互效应。随着年龄的增长，步态参数总体上有所改善。视力障碍个体的行走速度较慢，步长较短，支撑和双支撑阶段的持续时间延长。这些可能被视为平衡问题的适应，也可能是允许脚探测地面的策略。
