Who Is Step Width?

Step width was determined as the distance between the outer most borders of two consecutive footprints. Step time was determined as the time between initial foot-floor contact of one foot to the initial foot-floor contact of the contralateral side for two consecutive steps.

How do you determine the width of a step?

Stride width, also called base of support, is the distance between the heels of the two feet during double stance. Stride width is measured either between the medial-most borders of the two heels or between lines through the midline of the two heels.

Why is step width important?

The association between step width variability and fall risk has been inconsistent. Gabell and Nayak suggest that step width is related to balance control and that an increase in step width will lead to greater stability, a possible compensation for instability [4].
