GAIT SPEED MEASURE: THE EFFECT OF DIFFERENT MEASURING DISTANCES AND THE INCLUSION AND EXCLUSION OF ACCELERATION AND DECELERATION.

The purposes of this study were to examine the effects of different distances and the inclusion and exclusion of acceleration and deceleration distances on the measurement of self-paced and fastest gait speeds in younger and older adults. The self-paced and fastest gait speeds of younger and older adults were measured over 4-m and 10-m walkways with the acceleration and deceleration distances included and excluded in the measuring distance. The results indicated gait speeds (both self-paced and fastest) measured over different distances were comparable only if a distance for acceleration and deceleration was excluded from the measuring distance to obtain stable and comparable gait speeds. Similar results were found for younger and older groups. [ABSTRACT FROM AUTHOR]
