| Abstract: | The stride lengths, stride durations and walking speeds of visually impaired pedestrians were recorded under two conditions: firstly accompanied by a sighted guide, secondly walking independently. The same outdoor route was used for both conditions. When accompanied subjects walked at approximately the same speed as they would have on a force platform. However, when independent they were significantly slower (p = 0.051), with smaller strides (p = 0.083) which were of a longer duration (p = 0.062). Research into the gait of visually impaired pedestrians needs to take account of the effect of route conditions and the type of mobility aid being used. |
